Embodiment 1

[0022] The wood-plastic composite material floor of this embodiment is composed of the following materials by weight percentage:

[0023]

[0024] In this example, the following methods are used to prepare wood-plastic composite flooring:

[0025] Step 1, mixing materials, PVC plastic powder, wood fiber, mineral filling, foaming agent, foaming regulator, lubricant, titanium dioxide and pigment according to the stated ratio, first add PVC powder, stabilizer and stir until the friction heat When the temperature of the material rises to 40-60°C, add foaming regulator, mineral filler, and plant fiber. When the friction heat makes the material rise to 60-70°C, add lubricant and pigment (selected according to needs), and wait until the friction heat rises to 60-70°C. When the material rises to 100°C, add foaming agent, mix to 120-130°C, discharge the material into the cold mixer, and release the material when stirring and cooling to 20-70°C, to obtain plastic-wood mixture;

Abstract

The invention relates to a composite material floor and a preparation method, belonging to the technical field of materials. According to the invention, the plant fibers are continuously extended and distributed in the polyolefin wood-plastic profile. When the plastic-wood profile is stressed during use, the continuously extending fibers can quickly transmit the local force to the entire profile, thereby greatly improving the plastic-wood profile. strength and impact resistance. In addition, coconut shell powder or palm fiber is used in plant fibers, which is more environmentally friendly. The invention also helps to improve the surface oxidation resistance of plastic-wood composite materials by co-extruding the surface material, and at the same time improves the effect of scratch resistance and wear resistance, and co-extrudes the PVC soft rubber strip at the buckle to achieve excellent sealing. effect.

Description

technical field [0001] The invention relates to a composite material floor and a preparation method, belonging to the technical field of materials. Background technique [0002] Wood-plastic composite material is an emerging environmentally friendly, low-carbon composite material. It mainly uses recycled plastics and agricultural and forestry wastes as raw materials, which are processed into planks, guardrails, or indoor and outdoor decorations. However, due to the low mechanical properties of wood-plastic composite materials, they cannot be widely used in the construction field, especially for force-bearing parts or structural parts. At the same time, due to the limitations of the structural design and installation method of the current plastic wood flooring, the sealing of the installation interface cannot be guaranteed. The application of plastic-wood composite materials at home and abroad is currently in the development stage. How to enhance the performance of plastic-...
