Abstract

The invention discloses an alcohol-type adhesive double-effect assistant and a preparation method thereof. The alcohol-type adhesive double-effect assistant comprises the following raw materials: vinyltrimethoxysilane, 1,2-bis(trimethoxysilyl)ethane, 3-(2,3-epoxypropoxy)propyltrimethoxysilane and water. The single-component alcohol-type RTV (room-temperature vulcanizing) adhesive produced from the alcohol-type adhesive double-effect assistant can be used for firmly binding FR-4, glass, plastic, metal, ceramic and various other materials, and can implement quick deep curing under low-temperature dry conditions and other extreme climates. The alcohol-type adhesive double-effect assistant disclosed by the invention is safe, simple and environment-friendly to manufacture, and can overcome the defects of poor binding performance and slow deep curing (vulcanizing) in the national alcohol-type RTV adhesive.

Description

technical field [0001] The invention relates to a double-effect auxiliary agent for alcohol type glue, in particular to a preparation method and application of the double-effect auxiliary agent for alcohol type glue. Background technique [0002] Room temperature vulcanized silicone rubber is one of the main products of organic silicon. In my country, room temperature vulcanized silicone rubber is mainly divided into three types: dealcoholized, deacidified and deoximated. Dealcohol-type silicone rubber crosslinking agent is alkoxysiloxane (such as methyltriethoxysilane), vulcanization depends on the action of moisture in the air, slow vulcanization speed, poor storage performance, poor bonding performance; deacidification type The silicone rubber crosslinking agent is acetoxysiloxane (such as methyltriacetoxysilane), which releases acetic acid during the vulcanization process, which has a corrosive effect on metals and is not suitable for some precision equipment; deoximatio...
