Abstract

The invention relates to a polyethylene wood plastic and a preparation method thereof and belongs to the technical field of plastic compound modifying processing. The invention provides a formula of the polyethylene wood plastic and a preparation method for a section bar; extruding temperature and extruding speed are increased; a polyethylene wood plastic section bar produced according to the preparation method has excellent high-temperature resistance; and according to the technical scheme, the polyethylene wood plastic comprises the following raw materials in parts by weight: 30-40 parts of polyethylene, 50-70 parts of wood flour, 0.5-2 parts of maleic anhydride grafted polyethylene, 0.8-1.5 parts of polyethylene wax, 1-3 parts of zinc stearate, 2-6 parts of toner, 0.5-1 part of antioxidant, 0.4-0.9 part of anti-ultraviolet light absorber UV-531 and 0.5-1.2 parts of stearic acids. The preparation method provided by the invention is suitable for the extruding molding of the polyethylene wood plastic section bar.

Description

technical field [0001] The invention discloses a polyethylene wood-plastic and a preparation method thereof, belonging to the technical field of plastic compound modification processing. Background technique [0002] Forest resources play a vital role in protecting the ecological environment on which human beings depend. my country's wood consumption is very large, and more than 200,000 mu of forests need to be felled every year to meet the needs. Due to the deforestation of forest resources and the destruction of natural vegetation, the ecological environment is deteriorating day by day, and soil desertification is getting worse day by day. If a wood-like plastic factory is built, it can produce the equivalent of 1667m 3 The wood-plastic material of logs is equivalent to the wood output of about 174 mu of forest. In order to protect the ecological environment, people put forward the slogan of "give the forest to future generations" and put forward the request not to cut ...
