Preparation method of acid and alkali resistant synthetic glue

Abstract

The invention discloses a preparation method of an acid and alkali resistant synthetic adhesive. The preparation method comprises the following process steps: S1, preparing a main agent, wherein the main agent comprises alicyclic isocyanate and polyol resin; s2, preparing a curing agent, wherein the curing agent is prepared from the following components in parts by mass: 15 to 20 parts of alicyclic isocyanate, 100 to 105 parts of polyol resin, 0.02 to 0.04 part of a catalyst, 0.2 to 0.6 part of an antioxidant, 14 to 17 parts of a chain extender, 50 to 65 parts of a solvent, 3 to 5 parts of an anti-aging agent, 7 to 10 parts of a corrosion-resistant agent, 0.6 to 0.9 part of a hydrolysis-resistant stabilizer and 0.2 to 0.6 part of a wear-resistant agent; and S3, preparation of the synthetic glue: mixing the main agent and the curing agent in proportion to obtain the synthetic glue. According to the invention, the main agent and the curing agent are mixed and then heated and cured, and the cured main agent and curing agent have excellent binding power; the antioxidant and the corrosion-resistant agent are added into the curing agent, so that the acid and alkali resistance of the synthetic adhesive is improved; and meanwhile, the anti-aging agent, the hydrolysis-resistant stabilizer and the wear-resistant agent are added into the curing agent, so that the application range of the synthetic adhesive is widened.

Description

technical field

[0001] The invention relates to the technical field of industrial adhesive tapes, in particular to a method for preparing acid and alkali resistant synthetic adhesives. Background technique

[0002] Industrial tape is a general term for tapes used in various industrial occasions. It is mainly used to fix and protect various products, as well as provide protection for the production process and so on. Industrial tapes are widely used in many fields in China, such as industry, transportation, electronic communication, security, commerce, medical care, personal care, electronics, electrical, construction, culture, education and consumption. There are many types of industrial tapes, including single-sided industrial tapes and double-sided industrial tapes. There are also many bonding materials for industrial tapes, such as acrylic glue and silica gel. However, most industrial tapes have single functions and cannot be used in certain occasions. , so we propose a...
