Abstract
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
The present invention relates to the purifier apparatus field, is exactly a kind of adhesive film for filter that contains nano-attapulgite.
Background technology
Engine has air, machine oil, three kinds of purifiers of fuel oil, generally is called " three filters ".They undertake respectively the filtration of engine aspirating system, oiling system and firing system medium.Purifier is by the filtering to detrimental impurity originally, engine can be worked under various operating modes, and can reach rated wear.Can not can cause the engine premature wear of motor vehicle with the harmful dust impurity of engine is carried out effective filtering when the underproof product of filtration efficiency uses, reduce work-ing life, the harm engine even leads to a disaster.Engine has air, machine oil, three kinds of purifiers of fuel oil, generally is called " three filters ".They undertake respectively the filtration of engine aspirating system, oiling system and firing system medium.Purifier is by the filtering to detrimental impurity originally, engine can be worked under various operating modes, and can reach rated wear.Can not can cause the engine premature wear of motor vehicle with the harmful dust impurity of engine is carried out effective filtering when the underproof product of filtration efficiency uses, reduce work-ing life, the harm engine even leads to a disaster.Cause that purifier is defective mainly contains two reasons: the one, for the manufacture of the poor quality of the main raw material(s) filter paper of purifier, aperture is excessive, became uneven, perhaps the broken number of filter paper is very few, folding is wide too small, can not play due filteration, perhaps the intensity of filter paper is too low, produce and break after the air effect of certain flow, filtering efficiency significantly reduces.The 2nd, the adhesion process in producing is not grasped, or the poor quality of tackiness agent own, thereby make between filter paper and end cap, can not keep sealed state that dust is flow through in gap.The selection of filter paper and complete processing, filter paper adhesion process are two crucial qualifying points in the purifier Production Flow Chart.Some producer, in order to reduce production costs, purchases more cheap underproof filter paper and tackiness agent, or the bonding time is short, brush coating is very few or inhomogeneous etc., all can cause filtration efficiency defective.
Especially for air filter, its tackiness agent that uses with epoxy resin as main raw material, the tackiness agent of the type is fluid binder, must fully stir before using, adopt again the methods such as pickling process, spraying method, spread coating, rolling method, transfer method to operate, therefore comparatively complicated on technique, be prone to adhesive distribution inhomogeneous and cause the phenomenon such as waste; And tackiness agent is very crisp, not shock-resistant after solidifying, and is easy to damage in following process, transportation and installation process, causes purifier short work-ing life.
In addition, develop rapidly along with rubber industry, rubber composite is widely used, in rubber and metal composite goods, the quality of tackiness agent is the key of composite product quality, along with increasing and the expansion of Application Areas of composite product kind, more and more harsher to the requirement of adhesive techniques.The technology such as traditional chlorinated rubber method, isocyanic ester method can not meet new requirement, need new tackiness agent to improve the quality of rubber composite product.
Traditional rubber cement can not meet new requirement, is badly in need of the better rubber adhesive of performance and improves the quality of purifier.
