Abstract

The invention discloses an environment-friendly and antibacterial polypropylene plastic-wood composite board for buildings. The composite board is made from the following components by weight: 60-80 parts of polypropylene, 60-79 parts of rice straw powder, 40-50 parts of acrylic resin, 8-10 parts of caustic soda, 20-30 parts of urea, 12-18 parts of ammonium hydroxide, 5-9 parts of an acrylonitrile-butadiene styrene copolymer, 4-8 parts of calcium stearate, 2-5 parts of methyl ethyl ketoxime, and 4-8 parts of molybdenum dithiocarbamate. Compared with ordinary plastic sheets, the environment-friendly and antibacterial polypropylene plastic-wood composite board provided by the invention has more excellent antibacterial and anti-mildew performance, does not mildews or rots during use, has longer service life, and can be widely used in decoration, municipal gardens, docks and other occasions.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environment-friendly and antibacterial polypropylene-wood-plastic composite board for buildings. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly building material that has only emerged in recent years, and it has just started abroad. The raw materials used in wood-plastic products can be used as base materials such as waste plastics, waste wood, agricultural and forestry straws and other plant fibers, and do not contain any additional harmful ingredients. Moreover, it can be recycled and reused, which can be called a novel product of environmental protection, energy saving, and resource recycling in the true sense. [0003] "Wood-plastic material", also called "wood-plastic composite material", as the name suggests, can be understood as mainly using plastic as raw material, adding wood powder, rice...
