preparation example Construction

[0036] The present invention also provides a preparation process for the aforementioned paper-wood-plastic material, including:

[0037] A. Mix wood flour, waste paper scraps, recycled PP plastics, recycled PE plastics, fillers, and coupling agents, stir and heat to 90°C, add antioxidants and lubricants, stir and heat to 100°C;

[0038] B. Cold mixing for 5-10 minutes to remove moisture;

[0039] C. After cooling, the paper-wood-plastic material can be obtained.

[0040] The present invention also provides the application of the above-mentioned paper-wood-plastic material, which is used to prepare the paper-wood-plastic floor: the above-mentioned paper-wood-plastic material is transferred to a granulator for granulation, and then passed through an extruder equipped with a floor mould. Out of the machine, it is extruded into paper wood-plastic floor profiles.

Abstract

The present invention provides a paper wood-plastic composite material, a preparation process and application thereof. The material includes wood flour, paper scrap, recycled PP plastics, recycled PE plastics, an antioxidant, a filler, a lubricant and a coupling agent. The preparation process of the present invention includes the steps of: mixing wood flour, paper scrap, recycled PP plastics, recycled PE plastics, the filler and the coupling agent; stirring and heating to 90 DEG C; adding the antioxidant and lubricant, stirring and heating to 100 DGE C; conducting cold mixing for 5-10 min; and cooling to obtain the paper wood-plastic composite material. The added paper scrap is from wastepaper with low quality requirements, so as to eliminate the sorting process of the waste paper products and save energy.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a paper-wood-plastic material, its preparation process and its application. Background technique [0002] Wood-plastic material is a composite material filled with thermoplastics with wood powder, wood fiber or other plant fibers. [0003] Most of the wood-plastic materials currently used outdoors are made of PE plastic and wood powder as raw materials. [0004] In the prior art, in order to save cost and energy, the PE plastic used is recycled PE plastic, but the heat distortion temperature is low, which is not conducive to the use at a higher temperature. Contents of the invention [0005] In view of this, the present invention provides a paper-wood-plastic material, its preparation process and its application. By adjusting the formula, PP plastic and paper scraps are added, and the heat distortion temperature increases through the addition of paper scraps. At the same ti...
