Problems solved by technology

Traditional wood-plastic materials need to add more than or equal to 50% wood materials, the products are easy to absorb moisture, and the waterproof performance needs to be improved; in order to achieve the effect of imitating wood grain, it is generally necessary to carry out surface modification after molding, and the process is relatively cumbersome
However, the fully recyclable and recyclable wood-like materials prepared by the polymer resin are seldom reported.

Abstract

The invention discloses a fully plastic wood-imitation material and a preparation method thereof and relates to a wood-imitation material and a preparation method thereof. The fully plastic wood-imitation material comprises the following components in parts by weight: 100 parts of polystyrene, 20-40 parts of high impact polystyrene, 10-15 parts of resin, 2-5 parts of inorganic filling material, 0.5-2 parts of colorant and 1.5-3 parts of addition agent. The addition agent is mixed with the colorant to obtain a mixed material A; the resin and the inorganic filling material are dried; the polystyrene, the high impact polystyrene, the resin, the mixed A and the inorganic filling material are mixed to obtain a mixed material B; and the mixed material B is granulated, and then the obtained granules are molded to obtain the fully plastic wood-imitation material. Compared with the conventional wood-imitation material, the fully plastic wood-imitation material contains no wood component and no heavy metal, is waterproof, moistureproof, insect-resistant, anticorrosive and environment-friendly and contains low carbon. By injection or extrusion molding, the fully plastic wood-imitation material can be used without polishing, and products can be recovered by 100% and recycled.

Description

technical field [0001] The invention relates to a wood imitation material and a preparation method thereof, in particular to an all-plastic wood imitation material with plastic as the main raw material and a preparation method thereof. Background technique [0002] Imitation wood materials refer to a class of materials that have similar appearance, texture, physical and mechanical strength, and mechanical processing performance to wood materials. They can replace traditional wood materials in some fields such as home furnishing, garden construction, and logistics. [0003] Traditional wood-like materials mainly include wood-like materials on the surface of reinforced concrete, wood-like steel pipe materials, wood-plastic materials, etc., such as Huang Bangeng (referring to Chinese patent CN 1559770A) invented a kind of manufacturing method of wood-like prefabricated components for construction, which is to first Carry out shape processing, burning treatment, and then use woo...
