Problems solved by technology

[0002] Wood-plastic composite materials are widely used due to the dual advantages of plastic and wood fiber. It uses PP, PE, PVC and other resins instead of adhesives, and mixes them with more than 50% waste wood fibers, and then extrudes and molds them. , injection molding and other processes to produce profiles, compared with traditional wooden profiles, it has the advantages of water resistance, beauty, corrosion resistance, and not easy to crack. Currently, the structure of wood-plastic composite molding boards on the market is relatively simple. In order to highlight the woody feeling, Most of them directly use diamond brush and steel wire brush to directly polish the bright layer on the surface, and the texture formed is unnatural, which affects the appearance of the profile. Moreover, when some wood-plastic materials are molded, the flow effect of the molten material is poor, which affects the molding effect.

Abstract

The invention relates to an embossed and embossed wood-plastic profile which is prepared by the following steps: adding wood flour into a mixer in parts by weight, stirring at a constant speed, heating to 85-90 DEG C, adding lubricating particles, continuously stirring for 10 minutes, heating to 110 DEG C, adding high-density polyethylene and ethylene-acrylic acid copolymer, stirring at a constant speed for 5 minutes, adding inorganic filler, continuously stirring for 5 minutes to prepare a mixture, preparing a molten material, extruding and molding, and packaging to obtain the embossed and embossed wood-plastic profile. Adding the mixture into a screw extruder, extruding, forming a profile through a mold with a specific end surface, and forming embossment lines on the surface of the profile through embossment embossing equipment; according to the present invention, by blending to form the molten material, molding, and forming the embossment lines on the profile surface through the embossment embossing equipment, the specific embossment lines can be formed on the profile surface according to the requirements, and the lubricating particles are added during the molding process so as to easily improve the fluidity of the molten material, such that the molding is convenient, and the molding effect is improved.
