Abstract

The invention relates to a preparation method of a heat-resisting adhesive for connecting metal and PVC and belongs to the technical field of adhesives. The method comprises the following steps of, firstly, uniformly mixing and plasticating, by weight part, 50-70 parts of butyl rubber, 10-12 parts of acrylic resin, 5-10 parts of phenolic resin, 3-5 parts of polybutylene, 4-8 parts of tributyl phosphate, 10-20 parts of white carbon black on a rubber mixing mill, to obtain a mixture I; secondly, dissolving 5-10 parts of vinyl acetate resin into 10-20 parts of acetone and then uniformly mixing the mixture with antiager, stannous chloride and zinc oxide to obtain a mixture II; thirdly, adding and uniformly mixing the mixture I and the mixture II inside 70-90 parts of ethyl acetate to obtain the heat-resisting adhesive for connecting metal and PVC. The heat-resisting adhesive for connecting metal and PVC can still maintain relatively good adhesion strength after being used at high temperature.

Description

technical field [0001] The invention relates to a preparation method of a high-temperature-resistant adhesive used for connecting metal and PVC, and belongs to the technical field of adhesives. Background technique [0002] Adhesives for connecting metal to plastic can bond various difficult-to-stick transparent or white plastic products such as: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), ABS, nylon, sponge, film, foam Plastics, etc. It also has good adhesion to plexiglass, rubber, metal, bamboo wood, and fabric paper. It is especially unique in the mutual adhesion and cross-bonding of plastics, metals, and non-metallic materials. It is an ideal adhesive material for radio industry, decoration, packaging and printing industries. [0003] CN102585739 B discloses an adhesive used for bonding fluoroplastics and metals. The specific preparation method is to make acrylate containing -NCO by reacting hydroxyacrylate with diisocyanate, and seal -NCO with an e...
