Anaerobic oxygen rubber composition

Abstract

The invention relates to an adhesive compound with an anaerobic curing nature. An anaerobic adhesive compound comprises the following compositions according to the following mass percentage: 70 to 98 percent of a monomer or oligomer containing vinyl, 0.01 to 0.05 percent of a chelating agent, 0.5 to 5 percent of an organic peroxide initiator, 0.1 to 1 percent of organic hydrazide, 0.3 to 5 percent of saccharin, 0.01 to 0.5 percent of an inhibitor, and 0.001 to 0.5 percent of 1, 2, 3, 4-tetrahydroquinoline or derivatives thereof. The monomer used in the invention consists of acylic ester or methacrylic acid ester containing one to a plurality of base groups of -OH, -OCH3, -OCH2CH2-. The anaerobic adhesive compound which is characterized in low volatility, low odor and low toxicity can be widely applied to the locking and sealing of threads or the retention of cylindrical parts.

Description

technical field [0001] The present invention relates to adhesive compositions having anaerobic curing properties. Background technique [0002] The research on anaerobic adhesives began in the 1940s. The first practical variety was reported in the United States in 1953. After that, the technology became more and more perfect. In the mid-1960s, the American Loctite Company commercialized the product. Although companies from various countries have competed with it in the past ten years, Loctite is still the largest producer of anaerobic adhesives in the world, accounting for more than 80% of the total sales. Other manufacturers include companies such as Three Bond and 3M. The development of anaerobic adhesives in my country began in the early 1970s, and the first practical variety was developed in 1972 (XQ-1 Dalian), which promoted the attention and application of anaerobic adhesives by the Ministry of Machinery Industry. In the following ten years, Jinan (BN), Shanghai (Anc...
