A kind of high bonding flame-retardant adhesive and preparation method thereof

Abstract

The invention discloses a high-adhesion flame-retardant adhesive and a preparation method thereof. The flame retardant adhesive is prepared from hydrophobic vinyl monomers, polar vinyl monomers, multiple hydrogen bond functional monomers and flame retardant functional monomers through radical copolymerization. The present invention simultaneously introduces multiple hydrogen bond functional monomers and flame retardant functional monomers, simultaneously improves the flame retardant performance, adhesive performance and film strength of the adhesive, and prepares a flame retardant film with high adhesion and high film strength. type adhesive.

Description

A kind of high-adhesion flame-retardant adhesive and preparation method thereof (1) Technical field [0001] The present invention relates to a flame retardant adhesive and a preparation method thereof. (2) Background technology With the advancement of science and technology and the development of economy, industries such as aviation, automobile, electronics and packaging have the adhesiveness of adhesives. The requirements for energy and flame retardant performance are getting higher and higher, and the development of high-adhesion flame-retardant adhesives has become an important development method for the adhesive industry. Towards. Mainly at present is to improve the flame retardant performance of adhesive by the method of adding flame retardant after, but the flame retardant added after The adhesive will precipitate due to poor compatibility with the adhesive, resulting in a decrease in the adhesive performance of the adhesive [Polymer2020, 122917.]. By refining...

AI Technical Summary

Problems solved by technology

[0003] At present, the flame retardant performance of the adhesive is mainly improved by post-adding the flame retardant, but the post-added flame retardant will precipitate due to poor compatibility with the adhesive, resulting in a decrease in the adhesive performance of the adhesive [Polymer2020, 122917.]

By refining large-particle flame retardants to submicron and nanometer scales, the surface energy can be increased, while maintaining good flame retardancy, it can also weaken its influence on the adhesive performance of the adhesive, but it still cannot meet the requirements of aviation. , automotive, electronics and other high-end fields require high viscosity
