Problems solved by technology
However, products with unqualified original filtration efficiency cannot effectively filter out dust and impurities harmful to the engine, which will cause early wear and tear of the engine of the motor vehicle, reduce service life, endanger the engine and even cause accidents
There are two main reasons for the failure of the filter: one is that the quality of the filter paper, the main raw material used to manufacture the filter, is not good, the pore size is too large, the thickness is uneven, or the number of folds of the filter paper is too small, and the fold width is too small. It cannot play the proper filtering effect, or the strength of the filter paper is too low, and it will be broken after a certain flow of air, and the filtration efficiency will be greatly reduced
The second is that the gluing process in production is not well mastered, or the quality of the adhesive itself is not good, so that the seal between the filter paper and the end cover cannot be maintained, so that dust flows through the gap
The traditional chlorinated rubber method, isocyanate method and other technologies can no longer meet the new requirements, and new adhesives are needed to improve the quality of rubber composite products
[0005] The traditional rubber adhesive can no longer meet the new requirements, and a rubber adhesive with better performance is urgently needed to improve the quality of the filter

The present invention discloses filter adhesive film containing nanometer attapulgite, which is prepared from the following raw materials: neoprene CR121, styrene, 2,4,6-tris(dimethylaminomethyl)phenol, polyvinyl alcohol, N-2-(aminoethyl)-3-aminopropyl trimethoxysilane, polyisobutylene, polytetrahydrofuran ether diol, nanomter attapulgite, modified tree ashes and the like. The filter adhesive film is good in heat resistance, high in shear strength and excellent in electrical insulation and aging resistance. The adhesive film after curing is smooth in surface, and good in toughness and anti-seismic effect. By the mixing of chlorosulfonated polyethylene rubber and neoprene, the anti-aging performance and toughness of the filter adhesive film are increased, and the nanometer attapulgite plays a very good role of filling and reinforcing.
Description
technical field [0001] The invention relates to the field of filter equipment, in particular to an adhesive film for filters containing nano-attapulgite. Background technique [0002] The engine has three types of filters: air, oil, and fuel, generally referred to as "three filters". They are respectively responsible for the filtration of the medium in the engine intake system, lubrication system and combustion system. The filter is originally used to filter harmful impurities so that the engine can work normally under various working conditions and can reach the specified service life. However, products with unqualified original filtration efficiency cannot effectively filter out dust and impurities harmful to the engine when used, which will cause early wear and tear of the engine of the motor vehicle, reduce the service life, endanger the engine and even cause accidents. The engine has three types of filters: air, oil, and fuel, generally referred to as "three filte...
