Abstract

The invention provides a preparation method of wood-plastic composite material surface decoration based on UV-ink-jet 3D printing. The preparation method comprises following steps: cleaning and flattening the surface of a wood-plastic composite material, and putting the wood-plastic composite material in a UV-ink-jet 3D printer with the clean and flattened surface facing upwards; and adjusting patterns for surface decoration and printing parameters of the UV-ink-jet 3D printer, printing a resin material on the surface of the wood-plastic composite material, and preparing the UV-ink-jet 3D printing decoration on the surface of the wood-plastic composite material. According to the method, the surface decoration of the wood-plastic composite material is performed through UV-ink-jet 3D printing, problems that the surface of the wood-plastic composite material is difficult to decorate, the process is complex, the cost is high and the like are solved, and the method has very important significance in expanded application and high-added-value utilization of the wood-plastic composite material.

Description

technical field [0001] The invention relates to a preparation method for surface decoration of wood-plastic composite materials, in particular to a preparation method for surface decoration of wood-plastic composite materials based on UV-inkjet 3D printing, and belongs to the field of material decoration processing. Background technique [0002] Wood-plastic composite material is an environmentally friendly composite material prepared by compounding wood fiber materials and thermoplastics. Its raw materials can be agricultural and forestry waste (wood chips, wheat straw, etc.) Ethylene phthalate, etc.), which provides an effective way for the recycling of agricultural, forestry and plastic resources. Wood-plastic composites have the advantages of both wood and plastic, namely high strength, wear resistance, water resistance, corrosion resistance, durability, and no formaldehyde release. They have been widely used in construction, fences, floors, wall panels, etc. [0003] H...
