Problems solved by technology

[0003] Car air conditioners are already an essential part of existing cars. They can circulate the gas in the car. The air filter in the air conditioner can absorb harmful particles in the air, but it cannot absorb and decompose harmful gases in the room. ; It is also possible to discharge harmful gases into the air by opening windows, and when the ambient temperature is too high or too low, this discharge method is restricted; or purchase absorbent substances to absorb harmful gases, but this kind of adsorption Most of the harmful substances can only adsorb indoor pollutants without degrading them, which will cause secondary pollution and still have great harm to the human body

[0013] The present invention also provides a method for preparing the air purification filter element for vehicles, comprising the following steps:

[0014] (1) Mix organic silicate and organic titanate uniformly to obtain mixed solution A, mix cetyltrimethylammonium bromide and soluble metal salt in water uniformly, and then add to the mixed solution under stirring Add the mixed solution A to the system dropwise. After the dropwise addition, add a pH regulator to adjust the pH of the system to 5.3-6.2, then seal the mixed system at 100-160°C for 1-4 hours, and centrifugally wash and dry the product to obtain an intermediate product 1;

[0015] (2) After polyepichlorohydrin dimethylamine is uniformly dispersed in water, intermediate product 1 is added, ultrasonically reacted for 15-25 minutes, and then centrifugally washed and dried to obtain intermediate product 2;

[0016] (3) Ultrasonic disperse the intermediate product 2 and the polymer emulsion in the solvent evenly, the...

Abstract

The invention relates to the technical field of parts of automobiles, in particular to an automotive air purifying filter element. The automotive air purifying filter element is prepared from the following substances in parts by weight: 1-5 parts of organic titanate, 3-12 parts of organic silicate ester, 0.005-0.02 part of soluble metal salt, 6-20 parts of polyepichlorohydrin dimethylamine, 5-15 parts of hexadecyl trimethyl ammonium bromide, 1-5 parts of a foaming agent, 10-50 parts of a polymer emulsion, 1-10 parts of a pH regulator, 1-3 parts of a chain extender and 10-50 parts of a solvent.The automotive air purifying filter element can enrich and effectively degrade the harmful gas in the automobile, and the purpose of purifying air in the automobile is achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an air purification filter element for a vehicle. Background technique [0002] With the development of social economy, automobiles have become a common means of transportation. Since the interior parts of automobiles are mostly plastic products, the interior of the automobile, especially the new automobile, contains a large amount of volatile organic compounds (VOCs). If the concentration of VOCs in the automobile is too high It is easy to cause acute poisoning, and mild cases may cause headache, dizziness, nausea, vomiting, drunkenness and other symptoms; severe cases may cause liver poisoning and even coma soon, and some may even be life-threatening. Long-term exposure to VOCs in the car environment can also cause chronic poisoning, damage the liver and nervous system, and some may cause endocrine disorders and even leukemia. [0003] Car air conditioners are already an es...
