Problems solved by technology

As a commonly used filling material, precipitated silica has the characteristics of environmental protection, non-toxicity, low price, and reinforcement. It is used as a filler for anaerobic adhesives, which can reduce costs, increase hardness, and increase strength. But at the same time, due to precipitation Silica is easy to deposit as the storage time prolongs, resulting in stratification, resulting in a short storage time for anaerobic adhesives

Abstract

The invention discloses an anaerobic adhesive and a preparation method thereof. The anaerobic adhesive is composed of the following raw materials in parts by weight: 20-25 parts of hydroxyethyl methylacrylate, 8-15 parts of polyurethane acrylate, 8-12 parts of epoxy acrylate, 40-45 parts of precipitated silicon dioxide, 4-5 parts of a thixotropic agent, 1-2 parts of hydroxyethyl acrylate, 1-1.5 parts of trimethylolpropane triacrylate, 0.1-0.3 part of acrylic acid, 1-3 parts of isopropyl benzene hydroperoxide, 1-3 parts of N,N-dimethylaniline, 0.3-0.8 part of o-benzoic sulfimide, 0.5-1 part of a polymerization inhibitor, 0.1-0.5 part of a coupling agent and 0.01-0.05 part of disodium ethylene diamine tetraacetate. The anaerobic adhesive disclosed by the invention has the characteristics of being low in cost of raw materials, high in strength, high in hardness, high in viscosity and good in storage stability.

Description

technical field [0001] The present invention relates to the field of adhesives used in industry. More specifically, the present invention relates to an anaerobic adhesive and a preparation method thereof. Background technique [0002] In recent years, the development of anaerobic adhesives is getting faster and faster, and the market competition is also increasing. In this case, it is necessary to study an anaerobic adhesive with superior performance, low price and environmental friendliness. As a commonly used filling material, precipitated silica has the characteristics of environmental protection, non-toxicity, low price, and reinforcement. It is used as a filler for anaerobic adhesives, which can reduce costs, increase hardness, and increase strength. But at the same time, due to precipitation Silica is easy to deposit as the storage time prolongs, resulting in stratification, resulting in a short storage time for anaerobic adhesives. Contents of the invention [000...
