Title:
LIQUID RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2018/105704
Kind Code:
A1
Abstract:
Provided is a liquid resin composition which does not generate a toxic cyanogen gas when fired and is capable of maintaining flexibility even at low temperatures, and which is able to complete expansion molding in a short time by means of mixing at room temperature. A liquid resin composition which contains 100 parts by weight of a base resin (A), from 2 parts by weight to 100 parts by weight (inclusive) of a chemical foaming agent (B) and from 1 part by weight to 30 parts by weight (inclusive) of water (C). A polymer which has a hydrolyzable group bonded to a silicon atom, while containing at least one silicon group that is able to be crosslinked by forming a siloxane bond in the molecular chain, and which contains an oxyalkylene-based unit as a main chain constituting unit is used as the base resin (A). A bicarbonate (B-1) and an acidic compound (B-2) having an acid dissociation constant pKa of 3.0 or less are used as the chemical foaming agent (B). Consequently, a modified silicone resin foam which does not generate a toxic cyanogen gas when fired and is capable of maintaining flexibility even at low temperatures, while being able to be expansion molded in a short time by means of mixing at room temperature is able to be achieved.
