Abstract
The invention provides an acrylates waterborne coating gum, belonging to the technical field of textile printing and dyeing agents. The acrylates waterborne coating gum mainly comprises the following components by mass percent: 5-10% of ethyl methacrylate, 10-20% of polyacrylic ammonia ester, 1-3% of acrylamide, 5-15% of methacrylic acid dimethyl ammonia ethyl ester, 5-10% of acetone, 1-2% of a conditioning agent and the balance of a diluent. The acrylates waterborne coating gum is good in waterproof property and moisture permeability, soft, wear resistant and low temperature resistant; and a compact firm film can be formed on the surface of the textile, so that the adhesive property is high; and the utilization rate of the raw materials is high, and the cost is relatively low.
Description
Technical field
The present invention relates to textile printing and dyeing material technology field, esters of acrylic acid aqueous coating glue and production method thereof that especially a kind of waterproof and moisture permeability is good, soft wear-resisting and low temperature resistant.
Background technology
Fabric is called the fabric coating finish agent again with coating adhesive, is a kind of macromolecule compound that evenly is applied to fabric face.He forms one or more layers film through adhesive effect at fabric face, not only can improve the look and feel of fabric, and ear can increase fabric functional, makes fabric have waterproof. water pressure resistance, ventilating and moisture-permeable, properties such as inflaming-retarding antifouling and shading reflection.Ancient china before two thousand years, fabric just uses with coating adhesive the sixth of the twelve Earthly Branches, is mostly native compounds such as raw lacquer, tung oil, is mainly used in the making of WATERPROOF FABRIC.
Up to modern age, the multiple synthetic polymer type coating glue of superior performance has appearred. and initial product exists the air-locked shortcoming of a waterproof, and feeling of oppression and heat is arranged when coated fabric is taken; Comfortableness is poor, has limited its range of application, for improving the ventilating and moisture-permeable property of coating adhesive; From since the seventies; People have developed some new coating adhesives through means such as chemical structure modification and conversion coat processing methods, and the esters of acrylic acid WP is one of coating adhesive commonly used at present, and the Fabric Style of its processing is soft, fast light; Gasproof marquis property is good; General various clothes, the decoration materials of being used for, by its synthetic method and product proterties, this type of coating adhesive has the branch of solvent-borne type and emulsion-type; The adherence of solvent-borne type product and fabric is strong, can form the compact and firm film at fabric face, but because contain organic solvent, can cause environmental pollution, initiation fire, and solvent recovery is very expensive, and cost is higher; And the residual meeting of emulsifying agent on emulsion-type surface causes leaking of converted goods and dust suction.In addition, the cohesiveness of emulsion type products and fabric is low, and film forming is also such fine and close not as the solvent-borne type product, and its wear-resisting cooling property is also relatively poor.
Summary of the invention
For above-mentioned problem, the object of the present invention is to provide good, the soft wear-resisting and low temperature resistant esters of acrylic acid aqueous coating glue of a kind of waterproof and moisture permeability.
The technical solution adopted for the present invention to solve the technical problems is: this esters of acrylic acid aqueous coating glue main component comprises EMA, polyacrylic acid ammonia ester, acrylamide, dimethylaminoethyl acrylate methyl base ammonia ethyl ester, acetone, conditioning agent, diluent, and the mass fraction of various materials is:
EMA: 5%-10%, polyacrylic acid ammonia ester: 10%-20%, acrylamide: 1%-3%, dimethylaminoethyl acrylate methyl base ammonia ethyl ester: 5%-15%, acetone: 5%-10%, conditioning agent: 1%-2%, all the other are diluents.
As preferably, said conditioning agent is a sodium chloride.
As preferably, said diluent is a soft water.
A kind of preparation method of esters of acrylic acid aqueous coating glue, adopt following steps:
One, in agitated reactor, adds excessive dimethylaminoethyl acrylate methyl base ammonia ethyl ester;
Two, in agitated reactor, add acetone, stir;
Three, in agitated reactor, continue to add acrylamide and be stirred to dissolving fully;
Four, gained liquid in heating steps three agitated reactors, high-speed stirred, acrylamide, dimethylaminoethyl acrylate methyl base ammonia ethyl ester generate polyacrylic acid ammonia ester through emulsion reaction;
Five, leave standstill gained mixed liquor in the cooling step four, add conditioning agent then, diluent stirs;
Six, the environment of oxygen barrier, lucifuge encapsulation preservation down.
Beneficial effect of the present invention is: this esters of acrylic acid aqueous coating glue waterproof and moisture permeability is good, soft wear-resisting and low temperature resistant, and fabric face can form the compact and firm film, and adherence is strong, and utilization ratio of raw materials is high, and cost is lower.
The specific embodiment
Below in conjunction with embodiment the present invention is further specified:
In an embodiment, esters of acrylic acid aqueous coating glue main component of the present invention comprises EMA, polyacrylic acid ammonia ester, acrylamide, dimethylaminoethyl acrylate methyl base ammonia ethyl ester, acetone, conditioning agent, diluent, and the mass fraction of various materials is:
EMA: 5%-10%, polyacrylic acid ammonia ester: 10%-20%, acrylamide: 1%-3%, dimethylaminoethyl acrylate methyl base ammonia ethyl ester: 5%-15%, acetone: 5%-10%, conditioning agent: 1%-2%, all the other are diluents.
This esters of acrylic acid aqueous coating glue is white runny thixotroping decentralized photo emulsion; Emulsion is an ion-type, and according to the difference of interpolation conditioning agent, said esters of acrylic acid aqueous coating glue is acid, alkalescence or neutral; Solution is than thickness; Become the little yellow in transparent back, this esters of acrylic acid aqueous coating glue answers starvation to preserve, and prevents to go bad; Contain greatly polar group in this esters of acrylic acid aqueous coating glue, bonding and good film-forming property can form durability and refuse the water film on fabric, and the effect of these polar groups makes stream molecule to move, and makes coated fabric have better poisture-penetrability.
Above-mentioned esters of acrylic acid aqueous coating glue adopts following steps in the preparation process:
One, in agitated reactor, adds excessive dimethylaminoethyl acrylate methyl base ammonia ethyl ester;
Two, in agitated reactor, add acetone, stir;
Three, in agitated reactor, continue to add acrylamide and be stirred to dissolving fully;
Four, gained liquid in heating steps three agitated reactors, high-speed stirred, acrylamide, dimethylaminoethyl acrylate methyl base ammonia ethyl ester generate polyacrylic acid ammonia ester through emulsion reaction;
Five, leave standstill gained mixed liquor in the cooling step four, add conditioning agent then, diluent stirs.
Six, the environment of oxygen barrier, lucifuge encapsulation preservation down.
Said conditioning agent is a sodium chloride; Sodium chloride exists with ionic condition in the esters of acrylic acid aqueous coating glue, and this hydrophobic grouping of dimethylaminoethyl can change hydrophilic radical into after the ionization; Through the regulator solution ions content what, can further regulate its hydrophilicity.
Said diluent is a soft water, and soft water does not contain or contain less solubility calcium, magnesium compound, be difficult for other solution in substance reaction produce scum silica frost, its ion concentration is less, can not influence the performance of this esters of acrylic acid aqueous coating glue.
