Problems solved by technology

However, there is a fatal shortcoming in the method of using silane coupling agent as surface treatment agent, that is the instability of silane coupling agent, it is very easy to hydrolyze, so the environment of instant noodle treatment has a great influence on the bonding effect , must be processed in a low-humidity environment, and the bonding operation must be carried out immediately after processing, otherwise the bonding quality will fluctuate. In addition, the prepared processing agent must be kept in a strict seal, and it will fail if you are not careful. , it is difficult to adopt this method in the environment of factory mass production

Abstract

The invention discloses a fluorosilicone-metal adhesive and a preparation method thereof. The adhesive comprises epoxy resin, liquid polysulfide rubber, silicon dioxide, gamma-aminopropyl triethoxy silane, chlorosulfonated polyethylene, nitrile rubber, mica powder, vinyl triethoxy silane, dimethylformamide, diamino diphenyl sulfone, phthalate anhydride, 2-ethyl-4-methylimidazole, glycol methacrylate, a curing agent and an organic solvent. The preparation method comprises the following steps: adding epoxy resin, liquid polysulfide rubber, silicon dioxide, gamma-aminopropyl triethoxy silane, chlorosulfonated polyethylene, nitrile rubber, vinyl triethoxy silane, dimethylformamide and phthalate anhydride into an organic solvent to obtain a mixture I; mixing dimethylformamide, glycol methacrylate and the curing agent to obtain a mixture II; and mixing the mixture I and the mixture II and adding residual components to obtain the adhesive. The adhesive can be used for adhering fluorosilicone with various common metals such as copper, steel and aluminum.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a fluorosilicone rubber-metal adhesive and a preparation method thereof. Background technique [0002] Fluorosilicone rubber is a type of elastomer with siloxane (Si-O-Si) as the main chain and fluoroalkyl or fluoroaryl groups introduced into the side chains. Due to the introduction of the latter, this rubber not only It has many excellent properties unique to silicone rubber, such as: superior high and low temperature resistance, good flexibility, and it also has contact oil resistance and various chemical resistance like fluororubber. It is particularly worth mentioning that this rubber material has excellent stability for various petroleum-based fuels, lubricating oils, hydraulic oils and some synthetic oils, no matter at normal temperature or at high temperature. Therefore, its application scope is expanding day by day in modern aerospace, aviation, automobile,...
