The adhesive film after curing is smooth in surface, good in toughness and good in anti-seismic effect.

Description

A kind of chloroprene rubber and terpolymer EP rubber mixing and adhesive film for filter

Technical field

The present invention relates to the purifier apparatus field, be exactly a kind of chloroprene rubber and terpolymer EP rubber mixing and adhesive film for filter.

Background technology

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, thereby affect the work-ing life of purifier.

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.
