ADIABATIC MATERIAL COMPRISING EXPANDED PERLITE AND POL YURETHANE AND METHOD OF
PREPARING THE SAME AND CONSTRUCTION MATERIALS COMPRISING THE ADIABATIC MATERIAL Technical Field
[1] The present invention relates to an adabatic material comprising expanded perlite and polyurethane, a method of preparing the same, and construction materials comprising the adabatic material. In particular, the present invention relates to an adabatic material of light weight, excellent adabatic performance, fire resistance and flame retardance, comprising expanded perlite and polyurethane, a method of preparing the same, and construction materials comprising the adabatic material. Background Art
[2] Generally, an adabatic material is used in making buildngs, and mainly comprises expanded polystyrene (hereinafter referred to as EPS) and expanded polyurethane (hereinafter referred to as EPU). The EPS and EPU are lightweight, for example 100 kg/m3 or less, and low-priced, enable easy construction, and have excellent adabatic performance, and thus they are used in large quantities as an adabatic material of various buildngs or a core material of a sandwich panel. However, they have ds- advantages of easy burning, flame propagation and harmful gas generation, and thus they are very poor at heat resistance and flame retardance.
[3] To solve the problems of the conventional adabatic material, various adabatic materials with flame retardance have been developed, for example, typically a glass fiber, asbestos/rock wool materials, a polyester-based fiber material with treatment for flame resistance, or a polyolefin-based foam. However, the adabatic materials do not satisfy the requirements of adabatic performance and acoustic absorption or they are not lightweight and environmentally friendly, and thus they do not satisfy all of the requirements for construction materials, such as light weight, flame retardance, adabatic performance and economical efficiency.
[4] And, conventionally an adhesive used to prepare an adabatic material is an inorganic, water glass-based sodum silicate, a cement, a two-component polyurethane or a synthesized rubber-based adhesive. However, the inorganic adhesive is liable to break, and an organic adhesive has a high viscosity, and thus it has dfficulty in
inducing to completely coat an uneven surface of a perlite foam. Therefore, it is difficult to design a molding process so that the adiabatic material has effective flame retardnace and adiabatic performance.
[5] Korean Patent Registration No. 10-0530015 discloses a lightweight fire resistant material prepared by mixing expandable perlite, diatomaceous earth, a loess powder and an activated carbon as an inorganic compound, sodium silicate and alumina sol as an inorganic binder, and a thermosetting phenol resin, and compression-molding the mixture at a high temperature. The ingredients have excellent flame retardance, but have a larger weight than EPS or EPU. And, the ingredients are molded into a molded product by a molding process of a high temperature of 25O0C or more, and thus it is difficult to form a large area molded product, and manufacturing costs are increased due to the high temperature molding process. Disclosure of Invention Technical Problem

The adiabatic material of the present invention includes the plurality of expanded perlite first particles and expanded perlite second particles, having excellent adiabatic performance, and polyurethan as a binder resin. And, the plurality of expanded perlite second particles are mainly located in voids between the plurality of expanded perlite first particles, and thus the adiabatic material is lightweight, and effectively retards the fire progression to exhibit excellent adiabatic performance, fire resistance and flame retardance.
[8] The adiabatic material of the present invention may include 50 to 600 parts by weight of the expanded perlite first particles and 50 to 300 parts by weight of the expanded perlite second particles based on 100 parts by weight of the polyurethane
binder, and alternatively the adiabatic material may further include at least one flame retardant selected from the group consisting of a phosphorus-based flame retardant, a melamine-based flame retardant and an inorganic flame retardant.
[9] And, according to another aspect of the present invention, a method of preparing an adiabatic material includes (Sl) mixing uniformly a liquid type one -component water- blown polyurethane, the plurality of expanded perlite second particles, and water to prepare a paste; (S2) aάϊng the plurality of expanded perlite first particles to the paste, and mixing them uniformly; (S3) providing water to the mixture of the step S2 to foam and cure the one-component water-blown polyurethane; and (S4) drying the cured material.

And, the present invention is not limited to a specific particle diameter of the expanded perlite first particles, however the expanded perlite first particles having an average particle diameter of 2mm or more have the optimum effect. For example, the average particle diameter of the expanded perlite first particles may be between 2mm and 15mm, however the present invention is not limited in this regard.
[15] Preferably, an average particle diameter of the expanded perlite second particles that

For example, the average particle diameter of the expanded perlite second particles may be between 0.01mm and 2mm, however the present invention is not limited in this regard.
[16] In the case that the adiabatic material according to the present invention includes 50 to 600 parts by weight of the expanded perlite first particles and 50 to 300 parts by weight of the expanded perlite second particles based on 100 parts by weight of the polyurethane binder, the adiabatic material may have the optimum effect designed by the present invention.

[21] And, to uniformly mix the polyurethane with the expanded perlite first particles and the expanded perlite second particles, viscosity of the paste may be reduced for high fluidity. For example, the paste may be a high fluidity paste having viscosity of 300 cps or less, and for this purpose, 60 to 200 parts by weight of water may be used to prepare the paste based on 100 parts by weight of a mixture of the polyurethane and the expanded perlite second particles.
[22] In the case that a flame retardant is further included, preferably the flame retardant is added to the polyurethane before the expanded perlite second particles are added to the polyurethane, which may exhibit a flame retardant effect best. The flame retardant is included with a predetermined content, and the predetermined content is determined according to necessity of ordinary persons, for example 10 to 30 parts by weight based on 100 parts by weight of the polyurethane.
[23] Next, the expanded perlite first particles are added to the paste including the one- component water-blown polyurethane, the expanded perlite second particles and water, and they are mixed uniformly (S2).
[24] The present invention is not limited to a specific particle size of the expanded perlite first particles, for example an average particle diameter may be 2mm or more as mentioned above. And, the expanded perlite first particles may be added with a predetermined content, and the predetermined content is determined appropriately according to necessity of ordinary persons. For example, 50 to 600 parts by weight of the expanded perlite first particles are added based on 100 parts by weight of the polyurethane, which is preferable for the optimum adiabatic performance and fire resistance and light weight of the adiabatic material of the present invention.
[25] After the expanded perlite first particles are added to the paste, water is provided to the mixture to foam and cure the one-component water-blown polyurethane (S3).
[26] In the case that the one-component water-blown polyurethane is foamed according to the present invention, the adiabatic material may be formed of a desired shape using an appropriate mold according to necessity.
[27] After the polyurethane is foamed, the cured material is dried to prepare the adiabatic material of the present invention (S4).
[28] In this case, the method may further include an additional foaming step before the drying step according to necessity.
[29] The adiabatic material prepared according to the present invention as mentioned above may be used in various fields, for example construction materials.
[30] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The description proposed herein is just a preferable example for the purpose of illustrations only, not intended to limit the scope of the invention, so it should be understood that other equivalents and modifications could be made thereto without departing from the spirit and scope of the invention. The preferred embodiments of the present invention are provided to help persons having ordinary skills in the art understand the present invention more completely.

[36] Table 2 [Table 2] [Table ]
[37] As shown in Table 2, all of the molded products manufactured through the examples 1 to 4 exhibited excellent compressive strength of 20 kgf/cnf or more and density of 500 kg/m3 or less, and thus they satisfy the requirements of light weight.
[38] Example 2: thermal conductivity [39] The thermal conductivity of each molded product manufactured through the examples 1 to 4 was measured according to the standard KS L 9016-05, and results are shown in the below Table 3.

[44] Table 4
[Table 4] [Table ]
[45] As shown in Table 4, according to the tests for thermal radiation and gas harmfulness, the foam molded products according to the examples 1 to 4 of the present invention exceed a standard value used to determine quasHncombustible materials. That is, it is found that the adiabatic material according to the present invention is a high performance adiabatic material corresponding to a quasHncombustible material. Industrial Applicability
[46] The adiabatic material of the present invention uses two kinds of expanded perlite particles having different average particle diameters, in which expanded perlite particles of a relatively smaller average particle diameter locate in voids between expanded perlite particles of a relatively larger average particle diameter. Thus, the adiabatic material is a quasi-incombustible material having light weight, excellent adiabatic performance, fire resistance and flame retardance and the reduced likelihood of harmful gas generation in the case of exposure to flame. And, the present invention uses a one-component water-blown polyurethane as a binder resin, and thus the polyurethane is induced to foaming and curing by water and has a low viscosity of fluidity, so that the expanded perlite particles and the polyurethane binder are easily mixed, consequently a method for preparing the adiabatic material is simple. And, the method does not use a solvent, and thus is environmentally friendly.
