Problems solved by technology

[0002] Wood-plastic composite materials are prepared by mixing plastic and wood powder and other fibers, and have the characteristics of plastic and wood fibers at the same time, which not only improves the mechanical properties and processing properties of the material, reduces costs, expands the application range, but also improves the recycling of materials At the same time, compared with pure plastic materials, wood-plastic composite materials contain lignocellulose. In the case of relatively humid environment, the composite materials are easy to mildew and breed bacteria. Usually, pigments are added during the preparation of composite materials. Pigments of different colors can be added according to the color requirements of wood-plastic materials to prepare wood-plastic composite materials of different colors. Fades easily over time

Abstract

The invention discloses a wood plastic composite material with mixed-color flow lines. The wood plastic composite material is prepared from the raw materials comprising the following components: 55 to 65% of wood powder, 20 to 35% of high-density polyethylene, 7 to 12% of talcum powder, 2 to 3% of a grafted compatibility, 2.5 to 3.5% of a composite lubricant, 0.2 to 0.5% of an antioxidant, 0.2 to 0.5% of an ultraviolet adsorbent, 0.5 to 1% of a mould-proof antibacterial agent, and 0.2 to 0.5% of mixed-color flow line master batch. According to the wood plastic composite material disclosed by the invention, the prepared mixed-color flow line master batch is added in a production process of the wood plastic composite material, so that the color of the wood plastic composite material can be changed; and moreover, the prepared wood plastic composite material is bright in color and cannot fade under a long-term using condition.

Description

technical field [0001] The invention belongs to the field of preparation of wood-plastic composite materials, and relates to a flow pattern mixed-color wood-plastic composite material. Background technique [0002] Wood-plastic composite materials are prepared by mixing plastic and wood powder and other fibers, and have the characteristics of plastic and wood fibers at the same time, which not only improves the mechanical properties and processing properties of the material, reduces costs, expands the application range, but also improves the recycling of materials. At the same time, compared with pure plastic materials, wood-plastic composite materials contain lignocellulose. In the case of relatively humid environment, the composite materials are easy to mildew and breed bacteria. At the same time, the existing wood-plastic composite materials are designed to improve the appearance of materials , Usually, pigments are added during the preparation of composite materials.
