POLYPROPYLENE RESIN COMPOSITION AND METHOD FOR COATING MOLDED PRODUCTS OF THE RESIN COMPOSITION |
摘要 |
A polypropylene resin composition comprises (A) a polypropylene, (B) an ethylene-propylene-diene terpolymeric rubber having a Mooney viscosity, ML1+4 (100 DEG C), ranging from 5 to 50 and an iodine value of not less than 15, the component (B) ranging from 10 to 50% by weight on the basis of the total weight of the components (A) and (B), and optionally (C) an inorganic filler in an amount ranging from 0 to 40 parts by weight per 100 parts by weight of the sum of the components (A) and (B). A coating method comprises the steps of applying a primer coating to a molded product obtained by molding the foregoing polypropylene resin compostion or irradiating the molded product with plasma without degreasing and washing the product with a halogen atom-containing organic solvent and then applying a top coat to the product. Another coating method comprises the steps of degreasing and washing a molded product obtained by molding the foregoing polypropylene resin composition and then applying a top coat to the product without applying a primer coating to the molded product or irradiating the molded product with plasma. The coated film obtained according to the foregoing methods has good bond strength to the molded product. |
