LIQUID SILICONE RUBBER COMPOSITION AND PREPARATION METHOD THEREFOR

摘要

Disclosed are a liquid silicone rubber composition and a preparation method therefor. The liquid silicone rubber composition comprises 100 parts by weight of polydimethylsiloxane terminated with vinyl; 1-400 parts by weight of an inorganic reinforcing agent; 1-20 parts by weight of polydimethylsiloxane having a low viscosity and containing a vinyl on a side chain; 0.01-10 parts by weight of a crosslinking agent; 1-30 parts by weight of polydimethylsiloxane terminated with hydroxyl; and a platinum catalyst for curing the liquid silicone rubber composition. The liquid silicone rubber composition is applicable to an elastomer, a pressure roller, an image heating and fixing device in a copier and a laser printer, and some silicone rubber products.
