PREPARING METHOD FOR WATER DISPERSABLE SILICON-ACRYL-URETHANE RESIN AND AQUEOUS COATING COMPOSITION FOR AUTOMOBILE CONTAINING SAID WATER DISPERSABLE SILICON-ACRYL-URETHANE RESIN

摘要

The present invention is a silicone-acryl-relates to an automotive water-based coating material containing the preparation and the dispersed resin of the polyurethane dispersion of the resin composition, more particularly the core portion is made of a silicone acrylate and hydrophobic acrylic monomer shell part is made of a urethane silicone chain-it relates to a car for water-based coating composition containing a production method and the dispersion of the polyurethane resin dispersion of the resin-acrylic. Acrylic-silicon according to the production method of the present invention urethane dispersion resins are not only while maintaining the excellent properties of conventional acryl urethane resin has excellent adhesion, abrasion resistance, and chemical resistance by applying a silicon compound, conventional acrylic - there is a time of formation is improved the disadvantage of the water resistance of the polyurethane coating film gloss and stain resistance, excellent heat resistance benefits.
