Environment-friendly nano antibacterial PVC wood-plastic panel

Abstract

The invention discloses an environment-friendly nano antibacterial PVC wood-plastic panel. The environment-friendly nano antibacterial PVC wood-plastic panel is prepared from the following raw materials in parts by weight: 30-40 parts of wood flour, 120-150 parts of PVC, 2-4 parts of stearic acid, 10-14 parts of tributyl citrate, 0.5-1 part of polybenzimidazole, 10-15 part of an AC foaming agent and 20-30 parts of a chitin doped POSS modified bacteriostatic material. According to the environment-friendly nano antibacterial PVC wood-plastic panel, the dispersion property of a composite materialamong all base bodies can be well improved, POSS has good mechanical properties, and the mechanical strength of finished products can be effectively improved. The material of the environment-friendlynano antibacterial PVC wood-plastic panel has good environmental protection properties, does not contain toxic plasticizer raw materials, and has high use safety.

Description

technical field [0001] The invention belongs to the field of PVC materials, and in particular relates to an environment-friendly nano antibacterial PVC wood-plastic plate. Background technique [0002] Wood-plastic materials have good processing performance: wood-plastic composite materials contain plastic and fibers, so they have processing properties similar to wood, can be sawed, nailed, and planed, and can be completed with woodworking tools, and the nail-holding force Significantly better than other synthetic materials. Mechanical properties are superior to wood materials; good strength properties, wood-plastic composites contain plastic, so they have a better modulus of elasticity. In addition, because it contains fibers and is fully mixed with plastic, it has physical and mechanical properties equivalent to hardwood such as compression and bending resistance, and its durability is significantly better than ordinary wood materials; it has water resistance, corrosion r...

AI Technical Summary

Problems solved by technology

Long service life, up to more than 50 years; excellent adjustable performance: through additives, plastics can undergo changes such as polymerization, foaming, curing, modification, etc., thereby changing the characteristics of wood-plastic materials such as density and strength, and can also achieve Anti-aging, anti-static, flame retardant and other special requirements; it has ultraviolet light stability and good coloring properties: its biggest advantage is that it can turn waste into treasure, and can be 100% recycled and reproduced. It can be decomposed and will not cause "white pollution". A real green product; a wide range of raw materials: the plastic raw material for the production of wood-plastic composites is mainly high-density polyethylene or polypropylene, and the wood fiber can be wood flour, rice bran or wood fiber, and a small amount of additives and other processing aids are also required. It can be made into any shape and size according to the needs; at present, wood-plastic materials are often heavy as handicraft materials, which increases the cost of installation, handling and processing, and the dispersion of inorganic fillers in wood-plastic materials is poor, and the finished product The storage stability is not good, and at present, most wood-plastic materials do not have antibacterial properties, and wood-plastic furniture products are often placed in relatively humid areas. Therefore, how to improve the antibacterial properties of wood-plastic panels is very important
