Problems solved by technology

The bactericidal mechanism of titanium dioxide and zinc oxide is that they need to produce free radicals under light conditions, and then complete the sterilization. In some actual use occasions, the conditions of insufficient light may not be able to effectively sterilize.
Although the antibacterial melt-blown non-woven fabric uses chitosan, a natural antibacterial agent, the patent is to prepare an antibacterial melt-blown cloth through a post-processing method. For the use of natural antibacterial agents, the technology of directly obtaining antibacterial melt-blown materials is still rare

Abstract

The invention relates to an antibacterial melt-blown polypropylene material and a preparation method thereof. The antibacterial melt-blown polypropylene material is prepared from the following raw materials in parts by weight: 100 parts of polypropylene powder; 0.2 to 1.2 parts of an antioxidant; 0.2 to 1.2 parts of a lubricant; 0.2 to 0.7 part of peroxide; 0.4 to 1.8 parts of alkyl glycoside; the melt index of the polypropylene powder is 10 to 40 g / 10 min. The antibacterial melt-blown polypropylene material has good short-acting and long-acting antibacterial properties and excellent processability, and can be applied to the fields of air and liquid filtering materials, isolation materials, mask materials, thermal insulation materials and the like.

Description

technical field [0001] The invention relates to the field of materials, in particular to an antibacterial melt-blown grade polypropylene material and a preparation method thereof. Background technique [0002] Melt-blown polypropylene material is mainly used to prepare melt-blown cloth, which can be widely used in air, liquid filter materials, isolation materials, mask materials, thermal insulation materials and other fields. However, at present, the antibacterial efficiency of the melt-blown cloth prepared by ordinary melt-blown polypropylene material is low, and cannot meet the requirements of high-efficiency antibacterial. [0003] At present, a large number of antibacterial meltblown fabrics made of antibacterial meltblown polypropylene materials on the market are mainly realized by adding antibacterial agents to the raw materials. From the perspective of antibacterial agents, it can be divided into inorganic antibacterial agents, organic synthetic antibacterial agents ...
