Abstract

The invention discloses a wood-plastic board, which is composed of raw materials in the following weight ratios: PVC resin powder: 100 parts; plant fiber powder: 25-60 parts; calcium filler: 40-90 parts; plasticizing regulator: 0.5 ‑5 parts; processing aid superfine wollastonite powder: 0.5‑5 parts; environmental stabilizer: 3‑9 parts; ACR processing aid: 3‑12 parts; foaming agent: 0.5‑4 parts; internal and external lubricants: 0.5-3.5 parts, the particle size of the superfine wollastonite powder is at least 1500 mesh, and the upper material is mixed, heated, shaped and cut. The invention also discloses a production process. It is environmentally friendly, low in cost, and the cut surface of the product is neat, dense and free of pores, and its hardness, strength, and nail holding force are higher than the national standard, which can meet the effects of various post-processing requirements of the product.

Description

technical field [0001] The invention relates to a wood-plastic board, in particular to a wood-plastic board and a production process. Background technique [0002] With the improvement of people's awareness of environmental protection and energy saving, they are no longer satisfied with the wood waste of solid wood flooring and the high formaldehyde release of laminate flooring. There is an urgent need for a new type of building material that is energy-saving, low-cost, and easy-to-care. [0003] Wood-plastic composite material is a new type of material. It is made by mixing processed waste wood, sawdust, crop straw, and nut shells with thermoplastic materials in a certain proportion and treated with high temperature and high pressure. It has acid and alkali resistance. Will rot and other advantages. [0004] However, the quality of the current wood-plastic composite materials varies, and in terms of performance, they have different advantages and disadvantages in terms of ...
