Embodiment 1

[0022] Three different fillers are used to make wood-plastic products, namely wood powder, bran powder and bamboo powder. And test the physical properties of three different products. Batching by weight, wherein the consumption of PVC resin powder is 100 parts, and the consumption of wood powder or bran powder or bamboo powder is 30 parts, and the consumption of calcium powder is 30 parts, and the consumption of chlorinated polyethylene is 10 parts, The consumption of rare earth composite stabilizer is 5.0 parts, the consumption of polyethylene wax is 1.0 parts, the consumption of stearic acid is 3.0 parts, the consumption of foaming agent is 1.0 parts, and the consumption of acrylic foaming aid is 8 parts , the consumption of antioxidant is 0.5 part, the consumption of toner is 1.0 part, and the consumption of weather resistance agent is 0.5 part. Put the above materials into a high-temperature mixer, mix and dry them, and then put them into a twin-screw extruder for extrusi...

Embodiment 2

[0026] The products are extruded from three different plastics, namely high-density polyethylene (HDPE), polypropylene (PP), and polyvinyl chloride (PVC), and the physical properties of the three wood-plastic products are tested. Ingredients by weight, wherein the consumption of PVC or HDPE or PP resin powder is 100 parts, the consumption of wood powder (more than 80 orders) is 50 parts, the consumption of calcium powder is 30 parts, and the consumption of chlorinated polyethylene is 50 parts. 10 parts, the consumption of rare earth composite stabilizer is 4.0 parts, the consumption of polyethylene wax is 0.5 part, the consumption of stearic acid is 1.0 part, the consumption of blowing agent is 0.8 part, the consumption of the foaming auxiliary agent of acrylate 6 parts, the consumption of the reinforcing agent is 1.0 parts, the consumption of the toner is 1.2 parts, and the consumption of the weather resistance agent is 0.5 parts. Put the above materials into a high-temperatu...

Abstract

The invention relates to a novel wood plastic composite decorative building material and a manufacturing method thereof. The novel wood plastic composite decorative building material comprises the following components in part by weight: 100 parts of polyvinyl chloride (PVC) resin powder, 30 parts of mixture formed by mixing one or more of wood powder, bamboo powder, rice bran powder and crop straw powder in an arbitrary ratio, 30 parts of calcium powder, 5 to 10 parts of chlorinated polyethylene or MBS resin, 2 to 6 parts of rear earth compound stabilizer, 0.5 to 3 parts of polyethylene wax or oxidized polyethlene wax, 0.5 to 3 parts of stearic acid, 0.5 to 2.0 parts of foaming agent, 5 to 10 parts of blowing promoter, 0.5 to 1 part of antioxidant, 0.5 to 1 part of reinforcing agent, 1 to 3 parts of toner and 0.5 to 1 part of weather resistant agent. PVC plastic is modified by adding the auxiliaries, and the influence of unstable components (such as a vinyl chloride monomer, hydrogen chloride gas and the like) in the PVC on the performance of the building material is eliminated, so that the building material has better performance and environmental protection characteristics on the basis of keeping the original performance.

Description

technical field [0001] The invention relates to a novel wood-plastic composite decorative building material and a manufacturing method thereof. Background technique [0002] Wood-plastic composite material is a new type of composite material made of wood powder, bamboo powder, bran powder or crop straw powder and PVC, PE resin as the main raw materials through mixing and molding. It has the following characteristics: (1) can be processed and installed like wood, and can be painted; (2) durable, long life, similar to wood appearance, high hardness; (3) has excellent physical and mechanical properties, dimensional stability than wood Good, there will be no cracks and warping, no knot marks and twill lines of wood, and various colorful products can be made by adding colorants or composite surfaces; (4) Easy to shape, and can be shaped and processed with general plastic processing equipment (5) Not afraid of insect bites, aging resistance, corrosion resistance, low water absorp...
