Problems solved by technology

However, when the existing wood-plastic materials are applied to door and window products, especially when they are applied to aluminum-clad wood-plastic doors and windows, the strength of the doors and windows is not high enough, and they are prone to deformation. Performance and bending resistance put forward higher requirements

preparation example Construction

[0057] In a second aspect, the present invention provides a method for preparing a wood-plastic material, comprising the following steps: weighing each raw material in a formula amount, and then raising the temperature of resin, wood powder, rice husk powder, particle reinforcing agent and fiber reinforcing agent and stirring once, and finally adding the rest of the raw materials for second heating and second stirring to obtain the wood-plastic material. The above preparation method is simple and easy, and the produced wood-plastic material has the advantage of high strength.

[0058] In a preferred embodiment, the temperature is raised to 70-90°C once;

[0059] Preferably, the speed of a stirring is 150-500r / min;

[0060] Preferably, the temperature is raised to 90-120°C for the second time;

[0061] Preferably, the speed of secondary stirring is 700-1200r / min.

[0062] The formulation of the above parameters has fully considered the physical and chemical properties of eac...

Embodiment 1

[0067] A wood-plastic material, comprising the following raw materials in parts by weight: 35 parts by weight of PVC resin, 50 parts by weight of ash wood powder, 15 parts by weight of rice husk powder, 3 parts of aluminum oxide, 4 parts of carbon fiber, dibasic phthalic acid 2 parts of lead, 0.5 part of dioctyl phthalate, 2 parts of titanate coupling agent and 0.2 part of anti-aging agent.

Embodiment 2

[0080]A wood-plastic material, comprising the following raw materials in parts by weight: 35 parts by weight of PVC resin, 50 parts by weight of ash wood powder, 15 parts by weight of rice husk powder, 3 parts of aluminum oxide, 6 parts of carbon fiber, dibasic phthalic acid 2 parts of lead, 0.5 part of dioctyl phthalate, 2 parts of titanate coupling agent and 0.2 part of anti-aging agent.

[0081] The difference from Example 1 is that the weight ratios of alumina and carbon fibers are different.

Abstract

The invention relates to the fields of wood plastic materials and application thereof, and in particular provides a wood plastic material, aluminum-clad wood plastic window and door, and a preparation method thereof. The wood plastic material comprises the following raw materials in parts by weight: 30 to 40 parts of resin, 40 to 60 of wood powder, 10 to 20 parts of rice hull powder, 2 to 5 parts of a granule enhancer, 2 to 8 parts of a fiber enhancer, 1 to 3 parts of a heat stabilizer, 0.1 to 1 part of a plasticizer, 1 to 3 parts of a coupling agent, and 0.1 to 0.3 part of an anti-ageing agent. According to the wood plastic material, the granule enhancer and the fiber enhancer are added, so the comprehensive advantages of the granule enhancer and the fiber enhancer are completely exerted; the granule enhancer, the fiber enhancer and other components are reasonably coordinated, so that the hardness, the tensile resistance and the bending resistance of the wood plastic material can be obviously improved.

Description

technical field [0001] The invention relates to wood-plastic materials and the application field thereof, in particular to a wood-plastic material, aluminum-clad wood-plastic doors and windows and a preparation method thereof. Background technique [0002] Wood-plastic material is a modified thermoplastic material that is filled and reinforced with wood fiber or plant fiber, and made by hot-compression compounding, melt extrusion and other processing methods. In recent years, with the depletion of global resources, social awareness of environmental protection has been increasing, and higher requirements have been put forward for the application of wood and petrochemical products. In this context, wood-plastic composite materials can not only take advantage of the advantages of each component in the material, overcome the limitations of use caused by low wood strength, large variability, and low elastic modulus of organic materials, but also make full use of it. Waste wood a...
