Problems solved by technology

Traditional adhesives include acrylic adhesives, natural rubber adhesives and synthetic rubber adhesives. Among the three adhesives, synthetic rubber adhesives have the worst high temperature resistance, while acrylic adhesives have better high temperature resistance, but at higher temperatures, acrylic adhesives The heat resistance becomes worse and worse. As the temperature rises to 100°C, the peel strength of the tape will gradually decrease and the holding force will also decrease significantly.

Abstract

The invention relates to the technical field of refractory materials, in particular to a preparation method of anti-seismic and high-temperature-resistant glue. The preparation method comprises stepsas follows: step one, nitrile rubber is added to a stirrer and stirred uniformly, and is mixed and stirred uniformly with vinyltriisopropenyloxysilane, phenyltrimethoxysilane, octadecyl acrylate and ethylene glycol dimethacrylate; step two, nano-silica, polyvinyl alcohol, vinyl phenyl silicone oil, an emulsifier and a vulcanizing agent are added to an extruder for extrusion; step three, an extrudate and deionized water are added to the stirrer for continuous mixing and stirring; step four, a stirred substance is subjected to high-temperature desulfurization for a period of time, and plastic rubber is obtained; step five, the desulfurized plastic rubber passes through an open mill and a refining mill in sequence, and the anti-seismic and high-temperature-resistant glue is obtained. With theadoption of the technical scheme, the anti-seismic and high-temperature-resistant glue has good binding property, is not prone to falling off, has temperature resistance up to 200-300 DEG C, can be used for a long time and has certain anti-seismic capacity.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a preparation method of shock-resistant and high-temperature-resistant glue. Background technique [0002] What is heat-resistant glue? There is no strict classification standard at present. Generally speaking, high-temperature resistance should be evaluated according to whether it can maintain the bonding strength required by the design in a specific temperature, time and medium, or have a certain strength retention rate. However, the requirements of various industries are not exactly the same. If someone starts from the requirements of aircraft manufacturing, it is considered that the adhesive that can be used for a long time above 150 degrees is a high temperature resistant adhesive. Some people think that after 100 hours of heat aging, the heat aging temperature at which the strength retention rate is above 30% is the high temperature resistance of the adhesive....
