Problems solved by technology

[0002] At present, there are many composite filter elements in the field of filtration. The combination of filter elements with different filtering effects can make the filtering effect better and more convenient. This involves the bonding of matching filter elements. The bonding of filter elements uses adhesives. The current adhesives are heating curing type and room temperature curing type. The room temperature curing type does not need heating equipment and is suitable for small factories. The heating curing type requires heating, consumes energy, and has high production costs. Therefore, on the basis of increased production costs, how to It is very important to ensure the quality, so it is very necessary to develop a viscose that can complete the bonding of the filter element with high quality

Abstract

The invention a filter element adhesive for filter element connection, which is prepared from the following components in parts by weight: 90-100 parts of polyvinyl chloride paste resin, 15-35 parts of tackifying resin, 70-100 parts of plasticizer, 3-12 parts of modifier, 50-85 parts of filler and 10-40 parts of assistant. The polyvinyl chloride paste resin prepared by two methods is mixed as an binding agent, and has excellent comprehensive properties; the polyurethane resin is used as the tackifying resin, and has excellent tackifying property, technical properties and storage stability; the polyethylene terephthalate, epoxy resin oil and chlorinated paraffin used as the plasticizer are simultaneously used to obtain the optimal plasticity; the modifier is added to enhance the storage performance; the filler is added to lower the cost and the curing shrinkage; the assistant is added to improve the processibility of the adhesive; and thus, the adhesive has excellent binding effect, and can be used for binding different filter elements.
