Abstract

The invention belongs to the technical field of PVC plastic plates, and particularly relates to a PVC wood-plastic foaming antibacterial plate and a preparation method thereof. Raw materials comprisePVC resin powder, a foaming regulator, a filler, wood flour, a foaming agent, an antibacterial agent, a stabilizer, a lubricant, a matting agent and an ink absorption agent. According to the PVC wood-plastic foaming antibacterial plate, the wood powder filler is added into the formula of the plate, so that the specific gravity of the plate is reduced, and the plate is good in size stability, goodin rigidity, low in weight, high in strength and strong in wood texture; the matting agent compounded by silicon dioxide and a polypropylene graft is added, so that the prepared plate is low in surface reflectance and soft in gloss, the matt effect can improve the comfort level of the light environment, and people are not prone to visual fatigue; and the plate surface gloss is uniform and consistent, secondary processing and painting are not needed, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of PVC plastic boards, and in particular relates to a PVC wood-plastic foamed antibacterial board and a preparation method thereof. Background technique [0002] At present, with the development of social economy, people's living standards have been greatly improved, and the requirements for living environment and quality are getting higher and higher. Coupled with the international emphasis on environmental protection, traditional wooden decoration and decoration materials have gradually been replaced by artificial materials. , PVC plastic sheet is one of the products, it has been widely used in decoration, decoration, medical and health and transportation and other fields. However, due to the inherent defects of PVC plastics, PVC plastic sheets have some quality shortcomings, such as: mold and mildew spots on the sheet when it is damp and used for a long time; the sheet has low strength, low hardness, and ...
