Abstract

The invention discloses a formula of a plastic-wood board and a preparation method of the plastic-wood board. The plastic-wood board is prepared from, by weight, 40-60 parts of wood flour, 30-40 parts of plant fibers, 8-15 parts of an antifouling agent, 6-8 parts of zinc stearate, 4.2-6.4 parts of talcum powder, 2-6 parts of an antioxidant, 2-4 parts of a coupling agent, 2-4 parts of paraffin, 0.8-1.6 parts of a dispersing agent and 0.6-1.5 parts of a foaming agent. The plastic-wood board has the advantages that the plastic-wood board has good strength and corrosion resistance and is not prone to damage under severe conditions, and the application range of the plastic-wood board is broadened; the plastic-wood board also has thermoplasticity and is suitable for volume production.

Description

technical field [0001] The invention relates to a formula of a plastic wood board and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the awareness of environmental protection has also increased, and plastic wood panels have emerged as the times require. Plastic wood panels, with their good performance, gradually replace the original wood. The common wood-plastic boards on the market are obtained by combining PVC and wood chips. The compatibility of the wood-plastic board system in this way is poor, and once it encounters water or other harsh environments, it will have a greater impact on the board itself. Contents of the invention [0003] In order to solve the defects of the prior art, the object of the present invention is to provide a formula of wood-plastic board and its preparation method. [0004] The present invention is realized by adopting the following technical proposals: a formula of plastic wood ...
