Problems solved by technology

[0003] The existing PVC edge banding has good heat resistance and corrosion resistance, but it has less water content and poor conductivity. During the preparation process of PVC edge banding, it needs to go through operations such as kneading and extrusion. There will be different degrees of friction during the process, and when the edge banding is applied on the desktop or wardrobe, it will often rub against the clothes, causing the PVC edge banding to generate static electricity. According to the principle of mutual attraction of opposite charges, PVC with static electricity Edge banding is easy to absorb bacteria and dust in the air, which affects the appearance and quality of PVC edge banding

Abstract

The invention relates to the field of composite materials, and particularly discloses an antibacterial and antistatic edge band and a preparation method thereof. The edge band is prepared from, by weight, 45-55 parts of PVC resin, 20-30 parts of stone powder, 3-8 parts of a lubricant, 5-15 parts of a stabilizer, 1-3 parts of dye, 8-12 parts of a plasticizer, 5-10 parts of an antibacterial agent and 5-10 parts of an antistatic agent. The antibacterial agent is a nano-liposome dispersion liquid coated with chitosan quaternary ammonium salt; the antistatic agent is prepared by wrapping nano silver powder with mesoporous nano silicon dioxide, sodium dodecyl sulfate and mica powder. The edge band has antibacterial and antistatic effects. The preparation method comprises the following steps of weighing the raw materials in proportion, mixing, granulating, carrying out extrusion molding, and drying the printed pattern to obtain the edge band finished product. The method has the advantages ofsimple operation and easy production.

Description

technical field [0001] The application relates to the field of composite materials, more specifically, it relates to an antibacterial and antistatic edge banding and a preparation method thereof. Background technique [0002] Edge banding is a material for protecting, decorating and beautifying the section of furniture panels and other panels. Its main function is to seal the section of the panel to avoid damage to the panel due to adverse factors in the environment and during use, and to prevent The formaldehyde inside the board volatilizes, and at the same time achieves the effect of making a piece of furniture show clear wood grain and colorful decoration. [0003] The existing PVC edge banding has good heat resistance and corrosion resistance, but it has less water content and poor conductivity. During the preparation process of PVC edge banding, it needs to go through operations such as kneading and extrusion. There will be different degrees of friction during the proc...
