Problems solved by technology

[0004] The current anti-static wood-plastic profiles are prepared by one-time extrusion molding, and then apply anti-static paint on the surface of the prepared profiles. The paint will generate certain harmful gases and the service life of the paint is not long, and the paint surface is easy Shedding, limited anti-static ability

Embodiment 1

[0023] A method for preparing an antistatic wood-plastic composite profile, mainly comprising the following steps:

[0024] S1 material pretreatment: select waste and old recycled plastics, use a washing and drying machine to clean and dry the recycled plastics, and then pulverize them with a pulverizer, heat and soften the pulverized recycled plastics, and prepare them into a spherical shape with a radius of 0.5cm through a mold Structure, after cooling treatment, the surface of the formed plastic is polished and internally punched to make it contain through holes, and 200-mesh carbon fiber powder anti-static material particles are selected and ground into a powder with a radius of 400-500 mesh , waste plastics are: a mixture of low-density polyethylene, high-density polyethylene and polyethylene terephthalate;

[0025] S2 Preparation of anti-static plastic: put anti-static material powder and molded plastic into a vacuum defoaming high-speed oscillating mixer, set the vibrat...

Embodiment 2

[0030] The difference from the first embodiment is that the stabilizer in the present embodiment S4 adopts a composite lead salt stabilizer, and its lead content is 45%, and the oxidized PE wax is processed in conjunction with the composite lead salt stabilizer to make it thermally stable and electrically insulated The performance is better, and the antistatic performance of the prepared antistatic outer plate is improved by 8%.

Embodiment 3

[0032] The difference from the second example is that the temperature settings of the C1-C4 sections of the twin-screw extruder barrel in this example S4 are 185°C, 180°C, 165°C, and 155°C respectively, and the temperature settings of the mold D1-D4 sections are The temperature is set at 155-160°C, and the wood-plastic board extruded through the segmental heating method in Example 3 has stronger foaming texture, plastic resistance and ultraviolet resistance.

Abstract

The invention discloses a preparation method of an antistatic wood-plastic composite profile, mainly comprising the following steps of: selecting recycled plastic, preparing and molding the recycled plastic, punching the molded plastic, and stirring antistatic powder and the molded plastic in a vacuum defoaming high-speed oscillation stirrer; heating and stirring the selected materials in a heating furnace and then outputting to a pre-designed plate mold to be subjected to extrusion forming and shaping in a cooling liquid, and polishing the surface of the prepared plate to be smooth; controlling the water content of crop fibers, adding the crop fibers and kaolin into a high-speed mixer, sequentially adding auxiliaries, then adding the mixture into a double-screw extruder for extrusion shaping, and then heating and extruding the mixture into plates; and bonding the two plates through a hot melt adhesive. The wood-plastic composite profile disclosed by the invention has relatively stronganti-static capability and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of manufacturing wood-plastic composite profiles, in particular to a method for preparing antistatic wood-plastic composite profiles. Background technique [0002] Wood-plastic composite profiles are a reversible and recyclable basic material that has emerged in recent years. Wood-plastic composite materials have better quality than individual wood materials and plastic products. They are ideal substitutes for solid wood. Its appearance can Reducing the pollution of waste wood and plastics to the environment also adapts to the law of compound development of modern materials. [0003] Wood-plastic composite materials are based on primary biomass materials such as sawdust, wood chips, bamboo chips, rice husks, wheat straw, rice bran, soybean hulls, peanut shells, bagasse, and cotton straw. The characteristics of filling modification, compounding a certain proportion of plastic base materials, and processing a...
