Abstract

The invention discloses a PP plastic-wood composite board for a building. The PP plastic-wood composite board is made from the following components in parts by weight: 60-70 parts of PP, 60-70 parts of Chinese scholartree wood powder, 10-15 parts of EVA, 2-6 parts of aluminum sulphate, 3-7 parts of sodium borate, 4-8 parts of kaolin, 2-6 parts of diphthalate formic anhydride, 30-40 parts of peanut oil, 1-5 parts of bis(1-(tert-butylperoxy)-1-methylethyl)-benzene, 1-5 parts of glyceryl monoaliphatic ester and 3-5 parts of paraffine. A polypropylene plastic wood formula is unique and reasonable in design, under the premise that the shaping quality of PP plastic wood is guaranteed, original strength characteristics of the PP are reserved, and the production efficiency is greatly improved. Compared with a traditional PP formula technology, the PP plastic-wood composite board is notably improved and increased in a breakthrough manner.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a PP plastic-wood composite board for building. 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 straw 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 husk, straw and other waste plant fibers to mix into...
