Embodiment 1

[0027] A preparation process of PVC wood-plastic composite decorative board includes the following steps:

[0028] (1) Wood flour drying treatment:

[0029] The rubber wood powder is dried first, and dried until the overall water content is 4%, and then screened until the mesh size is 40-60 meshes for use;

[0030] (2) Wood flour modification treatment:

[0031] a. Put the rubber wood powder treated in step (1) into a steam explosion machine for steam explosion treatment, take it out and then immerse it in the silane coupling agent aqueous solution for 40 minutes, and finally take it out and dry it for use;

[0032] b. Immerse the rubber wood powder treated in operation a into the modified aqueous solution, and filter it out for use after immersion treatment for 25 minutes. The substances and their weight percentages in the modified aqueous solution are: 5% nano titanium dioxide, 0.8% Sodium hydroxide, the balance is water;

[0033] (3) Mixing and extrusion:

Description

Technical field [0001] The invention belongs to the technical field of material processing, and specifically relates to a preparation process of a PVC wood-plastic composite decorative board. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly material. It uses plant wood powder or wood fiber as a reinforcing filler. After pretreatment, it is mixed with thermoplastics (1 or more), and some other additives are added at the same time. After hot pressing , Extrusion, injection molding and other methods. Wood-plastic composite material has the dual characteristics of wood and plastic, and can be processed into a variety of colors. The texture and processing performance are similar to wood. At the same time, it also has stable chemical properties, high strength, good insect resistance, and can be recycled. The advantage is that it is an ideal substitute wood material. Excellent comprehensive properties make wood-plastic composite m...
