Polyolefin composite resin spherical particles, coating compositions, and, coated product
2010
By using the paint has a matte effect and soft feel, and to provide a polyolefin composite resin spherical particles can be obtained a coating film having excellent scratch resistance. Further, the coating composition containing the said polyolefin-based mixed resin spherical particles and coating resins, and to provide a coated product obtained by coating a coating composition to a substrate. The present invention, 100 parts by mass polyolefin resin, and water from 40 to 1,500 parts by mass, the ethylene oxide / propylene oxide copolymer 3 to 30 parts by weight of the weight average molecular weight from 4,000 to 30,000 are mixed, the best of the polyolefin resin after emulsification at a temperature above the melting point, at least 25 ° C. higher temperature than the maximum crystallization temperature of the polyolefin resin, to at least 25 ° C. lower temperature than the lowest crystallization temperature of the polyolefin resin, 0.2 ° C. a spherical particles obtained by cooling in / min or faster, the polyolefin-based resin, an ethylene / polyolefin composite resin vinyl acetate copolymer partially saponified to a composite resin containing 5 to 70 wt% it is a spherical particle.
