Title:
RESIN POWDER COMPOSITION FOR SLUSH MOLDING AND MOLDING
Document Type and Number:
Japanese Patent JP3909322
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain thermoplastic polyurethane resin powder for slush molding by finding an antiblocking agent not to cause mold deposit and using the antiblocking agent by considering that an antiblocking agent has a problem of causing mold deposit, increasing mold release resistance with it, reducing gloss on the surface of obtained skin and deteriorating an appearance in slush molding.
SOLUTION: The resin powder composition for slush molding comprises thermoplastic polyurethane resin powder as a main component and contains powder of fine particles of a maleimide copolymer not melting at a molding temperature and having crosslinked structure. For example, a copolymer of N-cyclohexylmaleimide and 2-hydroxyethyl (meth)acrylate, which is crosslinked with hexamethylene diisocyanate and/or isophorone diisocyanate is used as the fine particle powder.
