Problems solved by technology

However, the general accelerator primer only has a good curing acceleration effect on the surface of active metals, but the effect on the surface of non-metallic materials (plastics, etc.) is very poor, which cannot meet the needs of rapid assembly and fixing of modern industrial assembly line operations.

Abstract

The invention discloses an anaerobic adhesive promoting primer and a preparation method thereof. The anaerobic adhesive promoting primer mainly comprises a volatile organic solvent, organic metal salt, an accelerator and methacrylate. The preparation method of the anaerobic adhesive promoting primer comprises the following steps of: adding moderate methacrylate, organic metal salt and accelerator to the volatile organic solvent; stirring until the materials are dissolved completely; filtering the impurities to obtain the finished product. By adopting the anaerobic adhesive promoting primer, the positioning speed of the anaerobic adhesive can be raised by multiples during the process of adhering a nonmetal material, nearly 100% curing time is shortened, and the adhering intensity of the anaerobic adhesive to the nonmetal material is greatly improved. The anaerobic adhesive promoting primer also has the advantages of being fast in volatile speed, low in irritation to a human body, and small in environmental pollution.

Description

Technical field [0001] The invention belongs to the technical field of anaerobic adhesives, and in particular relates to an anaerobic adhesive accelerating primer and a preparation method thereof. Background technique [0002] Anaerobic adhesive sealant (anaerobic adhesive for short) is in a liquid state in the presence of oxygen. When used for assembling and fixing various mechanical parts, it solidifies quickly due to isolation from the air to achieve the purpose of bonding and sealing. Therefore, anaerobic adhesives are widely used in various machinery manufacturing and maintenance industries to prevent loosening, leakage prevention and bonding of parts. However, anaerobic adhesives currently on the market generally have problems with slow curing speed and short storage period. Although anaerobic adhesives can be applied as a single component on active metal surfaces such as copper and iron, their curing speed is slow on inert materials. Slow, especially more difficult t...
