Title:
GLASS FIBER-REINFORCED POLYAMIDE RESIN COMPOSITION, AND MOLDED ARTICLE FOR VEHICLE INTERIOR OR VEHICLE EXTERIOR COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/170909
Kind Code:
A1
Abstract:
The present invention is a glass fiber-reinforced polyamide resin composition that comprises a crystalline aliphatic polyamide resin (A), an amorphous polyamide resin (B), an acrylic resin (C), mica (D), glass fibers (E) and a carbon black masterbatch (F) at a mass ratio of (17-30):(10-16):(3-8):(10-25):(20-50):(1-8), wherein the mass ratio (B)/(A) of the (A) and (B) components is 0.50-0.61, and a copper compound is included at a proportion of 0.005-1.0 parts by mass if the total content of the (A)-(F) components is taken as 100 parts by mass. The glass fiber-reinforced polyamide resin composition is capable of forming a molded article that has a significantly superior surface appearance (textured surface uniformity) and has weather resistance such that the superior surface appearance can be maintained even after a weathering test.
