Antibacterial PVC wood plastic plate and preparation method thereof

Abstract

The invention discloses an antibacterial PVC wood plastic plate. The antibacterial PVC wood plastic plate is prepared from, by weight, 100 parts of PVC-1300, 20-30 parts of PVC-1000, 10-20 parts of C 9 petroleum resin, 40-50 parts of modified nano calcium carbonate, 6-8 parts of corn straw powder, 0.5-1 part of AC foaming agents, 0.3-0.6 part of sodium bicarbonate, 1-3 parts of calcium and zinc stabilizers, 2-3 parts of silane coupling agents KH550, 2-3 parts of ACR, 0.2-0.5 part of microcrystalline wax, 0.2-0.5 part of stearic acid, 3-4 parts of PVC foaming regulators ZB-530, 4-5 parts of molybdenum oxide, 0.5-1.0 part of ammonium polyphosphate, 1-1.5 parts of zinc borate, 0.2-0.4 part of nanometer titanium dioxide and 3-4 parts of polyhexamethyleneguanidine phosphate. Extrusion shaping is performed through a conventional extruding machine. The PVC plate has good antibacterial performance, meanwhile has good impact resistance and tensile strength and has the advantages of being resistant to chemical corrosion and low in cost.

Description

technical field [0001] The invention relates to the field of PVC boards, in particular to an antibacterial PVC wood-plastic board and a preparation method thereof. Background technique [0002] Wood-plastic composite materials are called wood-plastic composite materials in some occasions, and are called WoodPlasticComposite in many foreign materials, or WPC for short. Wood-plastic composite materials are made of plastic and wood fiber (or rice husk, wheat straw, corn stalk, peanut shell, etc.) Natural fiber) is a composite material made by adding a small amount of chemical additives and fillers and processed by special compounding equipment. It has both the main characteristics of plastic and wood, and can replace plastic and wood in many occasions, which has great development value for our country, which is seriously scarce in wood resources.

AI Technical Summary

Problems solved by technology

[0003] There are a large number of polar C-Cl bonds in the molecular chain structure of PVC resin in PVC wood-plastic composite boards, and there is a large force between molecules. Therefore, compared with other general-purpose resins, PVC is a hard and brittle material with low impact strength. , and has notch sensitivity, it is easy to be brittle when subjected to external impact, and it is difficult to be used as a structural material

These shortcomings greatly limit the development of PVC in the field of high performance. In order to expand its application range, it is necessary to toughen and modify rigid PVC.

Commonly used elastomer tougheners can better improve its impact resistance, but at the same time it will significantly reduce the rigidity of the material itself.
