Abstract

The invention discloses a polyvinyl chloride plastic adhesive, which comprises the following raw materials in parts by weight: 10-20 parts of PVC resin; 10-20 parts of CPVC resin powder; 30-40 parts of cyclohexanone; 30-40 parts of xylene 60-70 parts of dichloroethane; the present invention also relates to the preparation method of the polyvinyl chloride plastic adhesive, adopting CPVC resin powder and PVC resin to carry out dry mixing to obtain dry mixed resin, adopting dichloroethane as dry The primary dissolving solvent of mixed resin, dichloroethane realizes the rapid dissolution of CPVC resin powder in dry mixed resin, and after obtaining the primary dissolved adhesive, cyclohexanone and xylene are used to realize the dissolution of the primary dissolved adhesive again. Ultimate dissolution, less solvent consumption, no need to add additional additives, and the preparation process is simple, more importantly, the polyvinyl chloride plastic adhesive product prepared by the present invention has very excellent adhesion and durability It is very suitable as a large-scale preparation process route for high-end polyvinyl chloride plastic adhesive products.

Description

technical field

[0001] The invention relates to the field of adhesive preparation, in particular to a polyvinyl chloride plastic adhesive, and also relates to a preparation method of the polyvinyl chloride plastic adhesive. Background technique

[0002] Polyvinyl chloride plastic is widely used because of its light weight, high strength, excellent corrosion resistance, and good durability. In order to achieve the bonding application of polyvinyl chloride plastics, it is necessary to configure and consume a large amount of corresponding polyvinyl chloride plastic adhesives (commonly known as PVC adhesives). Therefore, the market capacity of polyvinyl chloride plastic adhesives is huge. of.

[0003] Specifically, the raw materials of existing polyvinyl chloride plastic adhesives usually consist of main resin, solvent and additives. Among them, the adhesive force and performance of polyvinyl chloride plastic adhesive mainly depend on the main resin. The performance of the mat...
