Abstract

The invention discloses broad-spectrum antimicrobial fragrant polypropylene resin for a washing machine. The resin is prepared from the following raw materials in percentage by weight: 60-84 percent of polypropylene, 0.2-1 percent of small molecule organic antibacterial agent, 0.2-1 percent of inorganic antimicrobial agent, 0.1-1 percent of freshener, 10-30 percent of glass fiber, 5-10 percent of compatilizer, 0.1-2 percent of dispersing agent and 0.1-1 percent of antioxygen. The invention further provides a preparation method of the broad-spectrum antimicrobial fragrant polypropylene resin for the washing machine. The broad-spectrum antimicrobial fragrant polypropylene resin for the washing machine has a broad-spectrum, efficient and lasting antibacterial function, and is higher in safety; washing machine water stirring blades or an washing machine inner barrel made of the resin provide clothing with specific fragrance; as the adding of the glass fibers, the resin has a stronger comprehensive mechanical property, and has low probability of deformation in the using process; the preparation process of the resin is simple, convenient, clean and efficient.

Description

technical field [0001] The invention relates to the technical field of polymer modification, in particular to a broad-spectrum antibacterial and fragrant polypropylene resin for washing machines and a preparation method thereof. Background technique [0002] As one of the five general-purpose plastics, polypropylene (PP) has the advantages of low density, low production cost, good comprehensive mechanical properties, non-toxic, corrosion resistance, easy processing and recycling, and is widely used in various fields, such as Household appliances, automotive interior and exterior trim, fitness equipment, office supplies, daily necessities, toys and sanitary ware, etc. Polypropylene products are exposed to bacteria and mold spaces, and a large number of bacteria will grow on the surface, which seriously endangers people's health. With the advancement of science and technology and economic development, people's awareness of health and environmental protection has gradually rea...
