Abstract

The invention discloses a high-gloss spray-free PP automobile bumper guard plate material and a preparation method thereof. Including the following components by weight percentage: polypropylene resin 36.6%-73.3%, MCPP resin 3.0%-8.0%, hydrogenated petroleum resin 5.0%-20.0%, toughening agent 3.0%-6.0%, antioxidant 0.2%-0.6 %, dispersant 0.2%-0.8%, inorganic filler 15.0%-25.0%, metal pigment 0.3%-3.0%. The preparation method includes compounding and extrusion granulation. The high-gloss spray-free PP automobile bumper guard plate material has relatively high gloss.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-gloss spray-free PP automobile bumper guard plate material and a preparation method thereof. Background technique [0002] PP resin with metallic pigments such as pearl powder, copper powder, and aluminum silver bars can be extruded and granulated to produce high-gloss metallic PP materials. Due to the reflection of metal pigments on light, this material has the characteristics of high gloss and metallic texture. It can replace spray paint materials in the fields of electronic appliances, cosmetic packaging, automotive materials, etc., thereby reducing environmental pollution and reducing costs. [0003] In recent years, with the increasingly stringent environmental protection regulations, the filling PP materials used in automobile materials for bumpers, bumper guards, and automobile side skirts have gradually begun to use spray-free materials. However, the ino...
