Abstract

The invention provides an antibacterial oil-stain-resistant polypropylene material and a preparation method thereof, and the antibacterial oil-stain-resistant polypropylene material comprises the following raw materials in parts by weight: 72-88 parts of polypropylene, 1-4 parts of antibacterial master batch, 1-3 parts of a hydrophobic and oleophobic agent, 8-20 parts of an inorganic filler, 0.4-1 part of an antioxidant and 0.3-1 part of a processing aid, the hydrophobic and oleophobic agent is a fluorine-containing acrylate polymer prepared by radiation emulsion polymerization of methacrylic acid perfluoroalkyl ethyl ester or methacrylic acid perfluoroalkyl butyl ester and lauryl acrylate according to a mass ratio of 4: (5-7). The antibacterial activity is improved by compounding the inorganic antibacterial agent and the organic antibacterial agent, and the hydrophobic and oleophobic agent has excellent low surface tension, so that the product is high in antibacterial activity and excellent in oil stain resistance, and the influence on the mechanical property of the material is very small.

Description

technical field [0001] The invention belongs to the technical field of polypropylene materials, and in particular relates to an antibacterial and oil-resistant polypropylene material and a preparation method thereof. Background technique [0002] As a general-purpose plastic, polypropylene has the characteristics of low density, good mechanical properties, non-toxicity, heat resistance, easy processing and molding, and low price. It has been widely used in automobiles, home appliances, packaging and other fields. Polypropylene resin is non-polar, and the oil stains produced in the kitchen are also non-polar. The use environment of home appliances is a high-temperature environment with high oil fumes and high humidity. Oil stains and oil spots are easily generated on the surface of polypropylene products. A large number of bacteria harmful to human health. In recent years, with the continuous improvement of modern society and living standards, people have higher and higher r...
