Abstract

The present invention is a high temperature resistant pre-coating anaerobic adhesive, which is composed of two components A and B, wherein, component A is composed of the following components according to the mass percentage: water 35%~55%? Wt; water-soluble thickener 3%~10%? Wt; Adhesive 1%~5%? Wt; polymerization accelerator 0.01%? Wt? ~3%? Wt; red pigment 0.1%~2%? Wt; filler 3%~15%? Wt; methacrylate monomer 25%~50%? Wt; heat-resistant additive 1%~20%? Wt; B component is the microcapsule initiator. The invention is suitable for thread locking under the high temperature condition of 200°C. The heat aging resistance of the product has been significantly improved, and has a wide range of application fields, which meets the needs of the current common pre-coated anaerobic adhesives that cannot adapt to the high temperature condition. , especially the inadequacies that cannot meet the conditions for locking at high temperatures.

Description

technical field [0001] The invention relates to a precoatable anaerobic adhesive and a preparation method thereof, which can be cured anaerobically and can be used in automobile manufacturing, aviation, military industry, general machinery, transportation machinery, oil fields, industrial and civil pipelines, and mold manufacturing Locking and sealing of various industrial threaded fasteners. Background technique [0002] The pre-coated anaerobic adhesive is composed of anaerobic emulsion and initiator-containing microcapsules. Compared with traditional liquid anaerobic adhesives, the sizing process can be carried out in advance and in a concentrated manner, eliminating the need for numerous coating equipment and construction personnel on the production line, and simplifying the production process. On-site operation improves production efficiency and ensures the quality of sizing. Therefore, pre-applied adhesives have made great progress in the field of modern machinery indu...
