Abstract

The invention discloses a self-adhesive organic silicon liquid silicone rubber for bonding a glass substrate and a forming process thereof. The self-adhesive organic silicon liquid silicone rubber comprises a component A, a component B and a component C. The component A comprises following components in parts by weight: 95.40-98.64 parts of a base material, 0.3-1.5 parts of a catalyst, 0.3-1.8 parts of an alkynol inhibitor and 0.5-2.0 parts of a binder. The component B is prepared from the following components in parts by weight: 89.72 to 97.74 parts of a base material, 1 to 8 parts of a crosslinking agent, 0.55 to 2.8 parts of a binding agent and 0.3 to 1.8 parts of an alkynol inhibitor; wherein the base material comprises the following components in parts by weight: 60-80 parts of vinylsilicone oil and 20-30 parts of white carbon black; the catalyst is a platinum catalyst, and the purity of the platinum catalyst is 1500 ppm. The cross-linking agent and the bonding agent are adopted,so that the self-adhesive organic silicon liquid silicone rubber can be powerfully combined with the surface of a glass substrate, and the adhesive force is enhanced.

Description

【Technical field】 [0001] The invention relates to the technical field of self-adhesive liquid silicone rubber, in particular to a self-adhesive liquid silicone rubber bonded to a glass substrate and a molding process thereof. 【Background technique】 [0002] Addition-type liquid silicone rubber has the characteristics of non-toxicity, good fluidity, small linear shrinkage, and rapid forming at high temperature. When processing it, liquid injection molding can be used. Liquid silicone rubber is accurately measured and continuously The feed enters the injection molding machine for vulcanization to produce the required silicone rubber products. Liquid silicone rubber injection molding process is simple, fast forming, high-quality products, widely used in automotive parts, electronic appliances, baby products, tableware and other fields. [0003] A significant shortcoming of addition-type liquid silicone rubber is that it has poor adhesion to most substrates. Improving its bondi...
