Silicone rubber powder and method of manufacturing thereof |
摘要 |
A silicone rubber powder obtained by curing a condensation-curable silicone rubber composition in a dispersed state in water, having an epoxy equivalent measured by a titration method equal to or lower than 3,000 and an average particle size in the range of 0.1 to 100 μm; and a method of manufacturing a silicone rubber powder comprising the steps of dispersing in water a silicone rubber composition comprising at least components (A) through (C) listed below; adding component (D); and curing the mixture: (A) a diorganopolysiloxane capped at both molecular terminals with silanol groups and having in one molecule 30 or less silicon atoms; (B) an organopolysiloxane having in one molecule at least two silicon-bonded hydrogen atoms; (C) an epoxy-containing alkoxysilane; and (D) a condensation-reaction catalyst. The silicone rubber powder has low epoxy equivalent and possesses excellent dispersibility in organic resins, and the method is efficient in manufacturing of the aforementioned powder. |
