Abstract

The invention discloses a low-odor sterilizing micro-foaming spray-free polypropylene composite material and a preparation method thereof. The polypropylene composite material is prepared from high crystalline polypropylene, micro-ball foaming agent, scratch-resistant resin, low volatile substance adsorbent, encapsulated enzyme, nano photocatalyst, a lubricant, and antioxidant according to parts by weight. The low volatile substance adsorbent has very strong adsorption and can effectively prevent forming parts of the composite material from generating low volatile harmful gases; the encapsulated enzyme and nano photocatalyst can decompose the low volatile harmful gases of the material into harmless carbon dioxide and water; and the high crystalline polypropylene has lower density, higher elasticity and proper rigidity after micro-ball foaming treatment. The material prepared by the method has good mechanical property, is light, resists heat and aging, is weather resistant, scratch resistant, and antistatic, has low odor, and contains low TVOC, thereby being applied to fields like automotive interior and high-grade decoration.

Description

technical field [0001] The invention relates to the technical field of modification of polypropylene materials, in particular to a micro-foaming spray-free polypropylene composite material with low odor and bactericidal function and a preparation method thereof. Background technique [0002] High crystalline polypropylene (HCPP) is a high-performance special resin with high surface hardness, low density, 0.9-0.91 g / cm3, isotacticity of 98%-99%, crystallinity of more than 70%, and high strength. , high heat resistance, high rigidity, excellent gloss, wear resistance, good bending fatigue resistance, performance close to engineering plastics. Since the crystallization temperature of HCPP is higher than that of ordinary polypropylene products, the product molding cycle can be greatly shortened, and the extremely low density makes it easy to make the manufactured products thinner and lighter. The disadvantage is that the shrinkage rate is large and it is relatively not scratch-...
