Abstract

The invention discloses a liquid silicone rubber and a preparation method thereof. The silicone rubber comprises the following components: alpha, omega-divinyl polysiloxane, alpha, omega-dyhydroxyl polydimethylsiloxane, divinyl tetramethyl disiloxane, a catalyst, an inhibitor, a filler and a crosslinking agent. The preparation method comprises the following steps: adding the alpha, omega-divinyl polysiloxane, the alpha, omega-dyhydroxyl polydimethylsiloxane, the catalyst and the filler in a reaction device by adopting a quantitative feeding device, performing thermal treatment at a temperature of 80-90 DEG C for 0.5-3h, adding the divinyl tetramethyl disiloxane, the crosslinking agent and the inhibitor, curing for 0.1-5h, after cooling by adopting a cooling device, filtering by means of a filtering device, and then filling and storing by adopting an automatic filling device. In order to overcome the defect of the prior art, the invention provides a liquid silicone rubber which is reasonable in components and ratio and good in adhering property, and a preparation method of the liquid silicone rubber.

Description

technical field [0001] The invention relates to a liquid silicone rubber; the invention also relates to a method for preparing the liquid silicone rubber. Background technique [0002] Adhesive refers to a kind of natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through the adhesion and cohesion of the interface, collectively referred to as glue. Adhesives, also known as adhesives, are customarily referred to as glue. In short, an adhesive is a substance that can bind adherends together through bonding; traditional adhesives have poor adhesion due to unreasonable formula ratios and cannot meet the needs of use. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a liquid silicone rubber with reasonable components and ratio and good bonding performance. [0004] Another object of the present invention is to provide a method for pr...
