Abstract

The invention discloses a two-component bonding nylon silica gel, belonging to the technical field of silicone rubber materials. The two-component bonding nylon silica gel comprises, by weight, 100 parts of methyl vinyl rubber containing 0.25% by mol of vinyl groups, 30-80 parts of fumed silica, 3-6 parts of hydroxyl silicone oil, 3-6 parts of vinyl triethoxysilane, 2 to 4 parts of stearic acid 1801, 3 to 5 parts of a binder, 0.5 to 5 parts of hydrogen-containing silicone oil, 0.5 to 5 parts of an inhibitor and 0.5 to 5 parts of a platinum complex. The two-component a bonding nylon silica gelprepared in the invention has excellent bonding performance with nylon, sufficient strength and good processing properties, is not prone to deformation, and can fully meet the requirements of food tableware.

Description

technical field [0001] The invention relates to the technical field of silicone rubber material manufacturing, in particular to a two-component bonding nylon silicone and a preparation method. Background technique [0002] Silicone rubber / nylon kitchen utensils are made of silica gel on the surface and nylon inside. They have many excellent properties such as environmental protection, high temperature resistance and chemical stability, and are more and more favored by consumers. Addition-type silicone rubber has a series of advantages: fast vulcanization speed, basically no small molecular substances are released during the vulcanization process, non-toxic and tasteless, and does not require secondary vulcanization, so it is widely used in food tableware. However, it is difficult to meet the requirements for the bonding strength of silicone rubber to be applied to the bonding of two-component and nylon. Therefore, it is of great significance to study the bonding of nylon and...
