Problems solved by technology

However, due to the use of toxic organic solvents in traditional acoustic profile adhesives, the production environment is bad and seriously affects the health of production workers. At the same time, the finished products will slowly release toxic organic solvents for a long time, which seriously affects their wide application in home decoration and building materials.

Abstract

The invention belongs to the technical field of adhesives, in particular to an adhesive and a preparation method thereof. The adhesive is prepared from, by weight, 18-22 parts of polyvinyl butyral resin, 8-10 parts of aldehyde ketone resin, 78-82 parts of ethanol, 17-19 parts of n-butanol, 6-10 parts of an aqueous formaldehyde solution, 3-5 parts of melamine and 22-26 parts of dibutyl phthalate. The adhesive is low in cost, moderate in viscosity, high in bonding strength, safe, environmentally friendly and capable of being widely used for sound insulation, sound attenuation and other aspects of home improvement building materials, the strength of bonded acoustic profiles is high, and meanwhile the preparation method is simple and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to an adhesive and a preparation method thereof. Background technique [0002] With the development of society, people pay more and more attention to sound pollution. Acoustic profiles have good sound insulation and noise reduction effects, low cost, and excellent acoustic effects, so they are widely used in various aspects such as home decoration and building materials. However, due to the use of toxic organic solvents in traditional acoustic profile adhesives, the production environment is bad and seriously affects the health of production workers. At the same time, the finished products will slowly release toxic organic solvents for a long time, which seriously affects their wide application in home decoration and building materials. . Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an adhesive and a preparati...
