Description
Technical field
The invention belongs to field of air filtration, it is related to a kind of air filter paper, particularly to a kind of light-high-strength glass
Fiber filter paper and preparation method thereof.
Background technology
All-glass paper/felt has fabulous fire-retardant, sound-absorbing, heat-insulating property, be provided simultaneously with light weight, inexpensive the advantages of.Mesh
Before, all-glass paper is widely used in fields such as household decoration, building external wall energy-saving insulation, air cleanings.Glass
Fiber air filter paper is the key components of filtering element for air filter, and the performance such as its thickness, grammes per square metre, intensity, rigidity determines
The performance of air filter.Glass fibre air filter paper is mainly used in the air filtration under special environment, by the air
The oil molecule of diffusion stops or is trapped in outside by air filting material, and protection is polluted the space of environment by oil molecule.Due to
Filter be by glass fibre air filter paper through giving a discount, machine is converted into filter element, is fixed on housing through PUR is fixed-type
On, therefore the thickness of glass fibre air filter paper, intensity must are fulfilled for the requirement of filter applying working condition, so that filter is suitable for
In different wind speed, flow it is adaptable to different ambient temperatures requires.
A kind of high-strength glass fiber air filter paper is disclosed on the Chinese patent of Publication No. CN 103721477 A
And preparation method thereof, this high-strength glass fiber air filter paper is made up of with adhesive glass fibre, and glass fibre is at one
In plane, uniform random distribution, forms micron-sized gap between multiple glass fibre, and adhesive wraps between glass fibre
On intertwined point, form netted joint face.Glass fibre is made up of glass chopped silk and/or glass fibre cotton, adhesive by
Inorganic silica gel or colloidal alumina or combinations thereof, overcome existing all-glass paper low intensity, high temperature filtration effect bad etc.
Shortcoming, this kind of high-strength glass fiber air filter paper can be used as building, the heat insulating element in the field such as machinery, heat energy or heat-insulated fill out
Material is it is also possible to be used for air cleaner.But the filter paper unit weight of this method preparation is larger, and filter efficiency is poor.
A kind of high-strength glass fiber air filter paper is disclosed on the Chinese patent of Publication No. CN 102505554 A,
Add the organic fibers such as terylene, aramid fiber, acrylon, polypropylene, polyvinyl, fibre length preferably 3～15mm in organic fiber, fiber is straight
Footpath preferably 0.3～5dan.Not only increase the intensity under glass fibre air filter paper normality and deflection, be dispersed in simultaneously
Organic fiber in page is melted into binding agent in high temperature, compensate for because of forfeiture after acrylic adhesive pyrolytic
Intensity.The high resiliency of organic fiber is it is ensured that the breathability of air filter paper and filter efficiency are it is ensured that the efficient sky made simultaneously
Air filter continuously can work at a temperature of more than or equal to 250 DEG C.But it is larger still to there is filter paper unit weight in this design
Problem, causes equipment energy consumption higher during use.
