Abstract

Silicone sealing materials, including: fillers, methyltrichlorosilane, chain extenders, crosslinking curing agents, aluminum hydrate ions and modifiers. The invention has stable performance, is not easy to be oxidized and yellowed, increases the polarity, greatly improves the adhesion of the silicone sealing material to the base material, realizes the coatability of the oil-soluble coating on the silicone sealing material and is suitable for various The base material has high adhesion.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to organic silicon sealing materials. Background technique [0002] Room temperature vulcanized silicone rubber is a common sealant with excellent high and low temperature resistance, aging resistance, and ultraviolet resistance, and is widely used in the construction industry. However, silicone sealants have low surface energy and low surface tension, and generally do not infiltrate paints. Even with paint applied, the adhesion is very low and comes off very easily. This greatly limits its development in the decoration industry. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides silicone sealing materials, including: [0004] Filler, methyltrichlorosilane, chain extender, crosslink curing agent, aluminum hydrate ion and modifier. [0005] The filler used is light CaCO treated with oleic acid, stearic a...
