Abstract

The invention provides a glass fiber air filtration filter material treating agent and a preparation method. The glass fiber air filtration filter material treating agent is characterized by being prepared from, by weight, 298-307 parts of acrylic acid, 13-18 parts of hydroxyethyl methylacrylate, 56-60 parts of sodium methallyl sulfonate, 200-235 parts of water, 20-30 parts of isopropyl alcohol, 7-13 parts of sodium persulfate and 32-36 parts of acrylonitrile through a solution polymerization method. A glass fiber filter material is treated, the strength and anti-abrasion and anti-bending performance of the glass fiber air filtration filter material can be effectively improved, and the treated glass fiber filter material is good in oxidation resistance, good in film forming transparency and not prone to resurgence.

Description

technical field [0001] The invention relates to a treatment agent for glass fiber air filter material. After the treatment, the glass fiber filter material has high strength, good wear resistance and good folding resistance, and has good film-forming transparency, good oxidation resistance and is not easy to regain moisture. Background technique [0002] The filter materials of air filters are natural fibers, synthetic fibers and glass fibers. Glass fiber filter material has the following advantages: stable filtration efficiency, at least 1 times longer life than chemical fiber filter material, working temperature up to 110-120 degrees Celsius, good anti-static effect, and high fire rating. [0003] However, glass fiber also has its disadvantages when used, that is, its strength is low, and its wear resistance and folding resistance are poor. Therefore, it must be treated with a glass fiber treatment agent to improve its strength, wear resistance and folding resistance It i...
