摘要： [Problem]
A purpose of the present invention is to provide a crosslinked organic silicon resin that can be dissolved in an oil agent that is liquid at room temperature, the crosslinked organic silicon resin becoming liquid, gum, or solid at room temperature when the oil agent is volatilized; and a method for preparing the same. Another purpose is to provide a cosmetic having exceptional applicability and richness and an excellent feeling on use, the cosmetic forming an emulsified product having a highwater content, freshness, and excellent stability over time, and to provide a crosslinked organic silicon resin that is capable of imparting a sunscreen effect and is less likely to form white residue or cause whitening in cosmetics that contain a UV scattering agent.
[Solution]
The present invention provides a crosslinked organic silicon resin represented by the average composition formula (1) and the method for preparing the same, wherein R1 is, independently of each other, unsubstituted or substituted, an alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, or an aralkyl group having 7 to 30 carbon atoms, R2 is, independently of each other, a polyoxyalkylene-containing group, a polyhydric alcohol-containing hydrocarbon group having two or more hydroxyl groups and/or alkoxy groups, or a group selected from the groups for R1, one or more of R2 in each R23SiO1/2 unit are a polyoxyalkylene-containing group or a polyhydric alcohol-containing hydrocarbon group having two or more hydroxyl groups and/or alkoxy groups, R3 is, independently of each other, an organopolysiloxane-containing group or a group selected from the groups for R1, each R33SiO1/2 unit has one or more organopolysiloxane-containing group, X is a divalent polyoxyalkylene-containing group represented by the formula (2) or a divalent group represented by the following formula (3), some of R2, R3 and X are optionally a hydroxyl group, a1, a2, a3, a4, b, c and d are numbers satisfying equations 0

摘要： The present invention provides addition-curable silicone rubber composition including: (A) 100 parts by mass of alkenyl-group-containing organopolysiloxane having two or more alkenyl groups bonded to a silicon atom within one molecule; (B) 0.2 to 20 parts by mass of organohydrogenpolysiloxane containing two or more hydrogen atoms bonded to a silicon atom within one molecule; (C) catalytic amount of a platinum-based catalyst; (D) 0.01 to 5.0 parts by mass of thermally-dissociative blocked (poly)isocyanate; and (E) 0.01 to 10.0 parts by mass of a heat resistance-imparting agent. The above can provide addition-curable silicone rubber composition and silicone rubber cured material which can produce a cured material having a low compressive set even under high temperature conditions of 200°C or more.
