Abstract

The invention relates to the technical field of PP (polypropylene) materials, particularly to a velvet surface antibacterial PP reinforced material and a preparation method thereof. The PP reinforced material comprises raw materials in parts by weight as follows: 60-80 parts of PP resin, 3-7 parts of a POE (polyolefin elastomer), 10-20 parts of filler, 2-4 parts of a surfactant, 0.5-1.5 parts of an antibacterial agent, 0.5-1.5 parts of a lubricant, 0.5-1.5 parts of a weather resistance agent, 0.3-0.7 parts of a coupling agent and 0.2-0.8 parts of an antioxidant. The raw materials are adopted, the weight ratio of the raw materials is strictly controlled, the prepared PP reinforced material has the velvet surface, can inhibit breeding of bacteria on the surface of a product, is clean and environment-friendly, and has the excellent comprehensive performance.

Description

Technical field [0001] The invention relates to the technical field of PP materials, in particular to a fleece surface antibacterial PP reinforcement material and a preparation method thereof. Background technique [0002] Polypropylene (PP material) is a kind of thermoplastic resin material made by polymerization of propylene. It is an important variety among the five general synthetic resins. PP has the smallest density among all synthetic resins, only 0.90-0.91g / cm 3 Among the five general-purpose plastics, PP has excellent heat resistance, PP is a non-polar polymer, has good electrical insulation, and PP has very low water absorption, and electrical insulation will not be affected by humidity. [0003] Therefore, polypropylene is made into various products through injection molding, extrusion, blow molding, and thermoforming methods, and is widely used in packaging, automobiles, home appliances, building materials, and chemicals. However, the existing PP materials cannot meet ...
