FLUOROSILICONE RUBBER COMPOSITION AND MOLDED ARTICLE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a liquid addition-curing type fluorosilicone rubber composition not adhering to a metal and capable of strongly adhering to a specific thermoplastic resin (a polyester-based resin and a polycarbonate resin) even without formulating a special adhesiveness-imparting agent or the like, to provide a fluorosilicone rubber molded article obtained by heat-curing the composition, and to provide an integrated molded article comprising a fluorosilicone rubber layer obtained by heat-curing the composition, and a thermoplastic resin layer.;SOLUTION: There is provided a fluorosilicone rubber composition containing the following components (A) to (D), and not adhering to a metal and capable of strongly adhering to a polyester-based resin and a polycarbonate resin: (A) 100 pts.mass of an organopolysiloxane represented by general formula (I) (wherein, R¹ to R⁴ are each a monovalent hydrocarbon group; and n is an integer of 150-500), and having a viscosity of 15,000-300,000 mPa s at 25°C; (B) an organohydrogenpolysiloxane containing two or more silicon atom-bonded hydrogen atoms in one molecule in an amount in which the number of the silicon atom-bonded hydrogen atoms contained in the component (B) is 0.5-10 per silicon atom-bonded alkenyl group in the component (A); (C) an addition reaction catalyst in an effective amount; and (D) 0-500 pts.mass of an inorganic filler. As a result, the liquid addition-curing type fluorosilicone rubber composition not adhering to the metal and capable of strongly adhering to a specific thermoplastic resin (polyester-based resin and polycarbonate resin) can be provided.;COPYRIGHT: (C)2013,JPO&INPIT
