Embodiment Construction

[0035] The preferred embodiments are cited below, and the present invention is described in detail as follows.

[0036] The raw material that following embodiment adopts is:

[0037] PVC: produced by Qilu Petrochemical Company, brand SG-8;

[0038] CPE: Produced by Jiangsu Tianteng Chemical Co., Ltd., brand CPE135;

[0039] Titanate coupling agent: produced by Shanghai Nuotai Chemical Co., Ltd., brand LH-22;

[0040] Wood powder: moisture content is 1%, fineness is 30 mesh;

[0041] Wood grain masterbatch: produced by Guangdong Changsheng Chemical Co., Ltd., brand F38.

Abstract

The invention relates to a PVC plastic-wood material which has large wood powder consumption, high strength and smooth appearance. The PVC plastic-wood material comprises the following components in parts by mass:100 parts of PVC, 30-50 parts of wood powder, 5-10 parts of chlorinated polyethylene, 0.1-0.3 part of methyl methacrylate, 0.3-0.5 part of AC foaming agent, 1-5 parts of plasticizer, 1-5 parts of foaming adjusting agent, 1-3 parts of calcium-zinc stabilizing agent, 0.2-0.5 part of octadecanoic acid, 0.5-2 parts of ceresin wax, 10-20 parts of light activated calcium carbonate, titanate coupling agent, maleic anhydride and 1-3 parts of antioxygen, wherein the mass ratio of the titanate coupling agent to the wood powder is 1:100-8:100, and the mass ratio of the maleic anhydride to the wood powder is 1:100-8:100. By adopting the proportion of the materials in the invention, the wood powder doping amount can be effectively improved, and the obtained PVC plastic-wood material has high strength and smooth appearance.

Description

technical field [0001] The invention relates to a PVC plastic wood material. Background technique [0002] WPC, as the name suggests, is a combination of solid wood and plastic. It not only maintains the affinity of solid wood, but also has good moisture-proof, water-resistant, acid and alkali resistance, anti-fungal, anti-static, anti-moth and other properties. A series of wood-plastic composite materials produced from waste such as sawdust, straw, and waste plastics are gradually entering the fields of decoration and construction. At present, the main product is PVC wood-plastic material obtained by combining wood chips and PVC. However, due to the poor compatibility of the system after adding wood powder, the strength of the product is reduced and the appearance is not smooth. Therefore, the amount of wood powder in general PVC wood-plastic materials is about 20% of that of PVC. Contents of the invention [0003] The invention provides a PVC wood-plastic material, whi...
