Abstract

The invention provides an epoxy resin-modified silicone rubber composite and applications thereof. The silicone rubber composite is prepared by mixing the following active ingredients in parts by weight: 80 parts of room-temperature vulcanized silicone rubber, 19-21 parts of EP01441-310 epoxy resin, 0.9-1.1 parts of KH-550 coupling agent, 1.3-1.7 parts of triethylene tetramine, and 2-4 parts of 501 reflux liquid. The epoxy resin-modified silicone rubber composite has the advantages of being cured at room temperature, having elasticity and high strength, and being good in metal bonding property and easy to repair; the epoxy resin-modified silicone rubber composite can be applied to encapsulate devices under the conditions of use temperature being minus 55 DEG C-120 DEG C, humidity being 95% below, anti-vibration power spectral density being 0.04g<2> / Hz, and all performance indexes can achieve the requirements of insulating, airtight and anti-vibration materials. The traditional silicone rubber is modified by adopting epoxy resin to meet the encapsulation and reinforcement requirements of devices such as cable plugs, sockets and the like applied in the industrial fields of aerospace, chemistry and the like, so that the devices can work normally under the severe environment conditions such as high temperature and low temperature, high humidity, mechanical vibration and the like.

Description

technical field [0001] The invention relates to a silicone rubber modified composition, which belongs to the field of adhesives such as insulation, sealing, and anti-vibration. Specifically, it relates to a silicone rubber composition modified by epoxy resin and its application. The silicone rubber composition It can meet the requirements of insulation, sealing and anti-vibration. Background technique [0002] Components used in aerospace, chemical and other industries need to work under harsh environmental conditions such as high and low temperature, high humidity, and mechanical vibration. For example, plugs and sockets of cables, resistors and capacitors on printed board assemblies and other components. In order to ensure that such components can work normally and reliably under harsh environmental conditions such as high and low temperature, high humidity, and mechanical vibration, it is key to use adhesives with certain elasticity and strength for potting and reinforce...
