Problems solved by technology

In order to reduce production costs, some manufacturers purchase cheaper unqualified filter paper and adhesives, or short bonding time, too little or uneven glue application, etc., will cause the original filtration efficiency to be unqualified
[0004] Especially for the air filter, the adhesive used is epoxy resin as the main raw material, this type of adhesive is a liquid adhesive, It must be fully stirred before use, and then operated by dipping method, spraying method, brushing method, roller coating method, transfer method, etc., so the process is relatively complicated, and it is prone to uneven distribution of adhesives and waste; and , the adhesive is very brittle after curing, not resistant to impact, and is easily damaged during subsequent processing, transportation and installation, resulting in a short service life of the filter
[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

Embodiment Construction

[0015] A kind of filter adhesive film that contains nano barite powder, it is made by the raw material of following parts by weight (kg):

[0016] Neoprene (CR121) 133, styrene 14, 2,4,6-tris(dimethylaminomethyl)phenol 2, polyvinyl alcohol 10, N-2-(aminoethyl)-3-aminopropyl Trimethoxysilane 2.5, polyisobutylene 2.3, polytetrahydrofuran ether glycol 2, cis-1,4-polyisoprene rubber 16, n-butyl methacrylate 8, isooctyl dithioglycolate di-n-octyltin 1, Stearic acid 2, zinc oxide 2.3, magnesium oxide 2.5, nano silicon dioxide 8, nano barite powder 43, nano bentonite 23, antioxidant 1035 2, 3-aminopropyltrimethoxysilane 3.4, accelerator CBS 1.2 , anti-aging agent NBC 1.5, anti-aging agent 4010NA 1.2, ferrocene 0.9, modified tree ash 2.3;

[0017] The preparation method of described modified tree ash is:

[0018] (1) Soak tree ashes in 12% hydrochloric acid solution for 4 hours, then wash with deionized water until neutral, and dry;

[0019] (2) Add 3% nano-carbon, 1% 2,4,6-tris(di...

Abstract

The present invention discloses filter adhesive film containing nano barite powder, 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, nano barite powder, modified tree ashes and the like. The strength of the filter adhesive film is improved efficiently by adding the nano barite powder. The filter adhesive film is good in heat resistance, high in adhesive strength and shear strength, and excellent in aging resistance. The adhesive film after curing is smooth in surface and good in toughness.

Description

technical field [0001] The invention relates to the field of filter equipment, in particular to an adhesive film for filters containing nano barite powder. Background technique [0002] 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. [0003] The gluing process in production is not well mastered, or the quality of the adhesive itself is not good, so that the filter paper and the end cover of the filter cannot be kept in a sealed state, so that dust flows through the gap, resulting in unqualified filter quality. The selection and processing of filter paper and the gl...
