Title:
POLYURETHANE ELASTOMER-FORMING COMPOSITION, INDUSTRIAL MACHINE COMPONENT USING SAME, MOLD RELEASE AGENT COMPOSITION USED FOR RESIN MOLDING, AND POLYURETHANE RESIN MOLDED ARTICLE WHICH IS MOLDED USING SAID MOLD RELEASE AGENT COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/035865
Kind Code:
A1
Abstract:
To provide a thermosetting polyurethane elastomer which is free from the occurrence of bleeding and blooming, and which has extremely low coefficient of friction.
The present invention solves a problem by introducing, into a thermosetting polyurethane elastomer-forming composition, at least one substance selected from the group consisting of polyoxyethylene alkyl ethers and linear aliphatic alcohols having 20-40 carbon atoms and a melting point of 90°C or less, and additionally octadecyl isocyanate in order to achieve a better effect, or alternatively, by introducing an aliphatic amide and at least one substance selected from the group consisting of polyoxyethylene alkyl ethers, linear aliphatic alcohols having 20-40 carbon atoms and a melting point of 90°C or less and octadecyl isocyanate. The present invention solves another problem by using, for resin molding, a mold release agent composition which contains an organopolysiloxane having at least one carboxylate selected from the group consisting of quaternary ammonium and quaternary phosphonium in the molecular structure.
