Title:
A METHOD FOR PREPARING ORGANOPOLYSILOXANE RESINS
Document Type and Number:
WIPO Patent Application WO/2017/185737
Kind Code:
A1
Abstract:
The present invention discloses a method for preparing organopolysiloxane resins, comprising the steps below: (1) use alkoxysilane, capping agent and an acidic compound as raw materials; (2) mix all the raw materials till uniform, herein capping agent, alkoxysilane and acidic compound have a mole ratio from 0 to 40: 1: 0.2 to 5; (3) polycondensation reaction occurs on temperature 40～150°C in 2～20h; (4) adjust the condensation product to neutral, and obtaining a product of organopolysiloxane resin after purification. Preparation of organopolysiloxane resins with the present invention method has benefits on less environmental pollution, low energy consumption, efficient productivity, high yield of silicone resin with excellent performance.
