High-temperature resistant anaerobic locking glue and preparation method thereof

Abstract

The invention relates to a high-temperature resistant anaerobic locking glue and a preparation method of the high-temperature resistant anaerobic locking glue. The anaerobic locking glue comprises 45 parts of (2) ethoxylated bisphenol A dimethacrylate, 20 parts of hydroxypropyl methacrylate, 15 parts of boric acid, 12.39 parts of bisphenol A fumaric acid polyester, 3 parts of fumed silica, 0.8 part of benzoic hydrazine, 0.6 part of o-benzene sulfonyl imine, 1.0 part of ethylenediamine tetraacetic acid disodium salt, 2.0 parts of cumene hydroperoxide, 0.2 part of fast red, and 0.01 part of para-benzoquinone. The anaerobic locking glue can be used for a short time at the temperature blow 230 DEG C and a long time at the temperature above 200 DEG C. The thermal aging resistance of the anaerobic locking glue at 230 DEG C is improved significantly. The anaerobic locking glue has a wide range of application and overcomes the defects that the existing ordinary anaerobic glue can not adapt to the high-temperature working condition.

Description

technical field [0001] The invention relates to anaerobic adhesives, in particular to high temperature resistant anaerobic adhesives suitable for occasions requiring a certain locking torque at high temperatures and a preparation method thereof. The anaerobic adhesive can be used in various industrial fields such as automobile manufacturing, aviation, military industry, general machinery, transportation machinery, oil fields, industrial and civil pipelines, and mold manufacturing. Background technique [0002] With the development of modern science and technology, anaerobic adhesives have played an increasingly important role in people's lives. Especially in the automobile manufacturing industry and the rail transit industry, anaerobic adhesives have replaced the traditional anti-loosening sealing methods, which not only ensures the quality, but also reduces the cost and facilitates the operation of workers. However, most of the current anaerobic adhesives are traditional a...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the above-mentioned problems. By adding a certain amount of boric acid to cooperate with other monomers, initiators, accelerators, surfactants and stabilizers, an anaerobic adhesive with high temperature resistance is prepared to solve the problem of common anaerobic problems. Due to the problem that the glue cannot withstand high temperature, the temperature resistance of the anaerobic glue can reach above 230°C, and it has long-term heat aging resistance;
