Abstract

The invention discloses a high-temperature-resistant anaerobic borosilicate resin hybrid acrylate adhesive and a preparation method thereof, and relates to a modified anaerobic acrylate adhesive and a preparation method thereof. The invention aims at solving the problems of low heat-resistance temperature and complex preparation process of the existing anaerobic acrylate adhesives. The adhesive is prepared from an anaerobic acrylate monomer, a stabilizer, heat-resistant additive, an accelerant, a cure activator, borosilicate resin and an initiator. The preparation method comprises the following steps of: adding the stabilizer in the anaerobic acrylate monomer; then sequentially adding the accelerant and the cure activator, stirring and dissolving, and then adding the heat-resistant additive and the borosilicate resin; and finally adding the initiator, and uniformly stirring to obtain the high-temperature-resistant anaerobic adhesive. The high-temperature-resistant anaerobic adhesive disclosed by the invention is capable of being cured at a room temperature, simple in production process, capable of achieving a heat-resistance temperature of 350-400 DEG C, and good in adhesive performance. The high-temperature-resistant anaerobic adhesive disclosed by the invention is mainly applied to the field of adhesives.

Description

technical field [0001] The invention relates to a modified acrylate anaerobic adhesive and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of high-tech industries such as aerospace, aircraft manufacturing, precision electronics, and machining, higher requirements have been placed on the high strength and heat resistance of adhesives, such as sensors for internal combustion engines, rocket engines, and nuclear reactors. The locking of threaded parts such as joints, flanges and pipe threads all requires high temperature resistant adhesives. [0003] Anaerobic adhesives have the characteristics of high bonding strength, small volume shrinkage, room temperature curing and wide applicability, so they have been widely used in various fields. However, due to the relatively poor heat resistance of anaerobic adhesives, for example, the long-term use temperature of commercially available anaerobic adhesives is 150°C, and after a...
