On-line embossed high-strength antiskid plastic-wood composite material plate and preparation method thereof

Abstract

A on-line embossed high-strength antiskid plastic-wood composite material plate is prepared from high-density polyethylene plastic particles, a substituted benzamide nucleating agent TMB-5, oily woodflour, modified graphene, calcium carbonate powder, terpene resin, butyl stearate and oxidized polyethylene. The plate is prepared by following steps: uniformly mixing the high-density polyethylene plastic particles with the substituted benzamide nucleating agent TMB-5, carrying out melt extrusion to form a crystalline plastic material flow; uniformly mixing high-density polyethylene plastic particles, oily wood powder, modified graphene, calcium carbonate powder, terpene resin, butyl stearate and oxidized polyethylene, carrying out melt extrusion to obtain a plastic-wood material flow; uniformly mixing the two material flows in a mixing machine head, extruding to form a plastic-wood plate; and rolling and embossing the plastic-wood plate for two times at a certain temperature. The production is convenient, the mechanization degree is high in the production process, the required labor force is little, the cost is low, and the plate is environment-friendly, strong in wood texture, freeof deformation, water resistant, aging resistant, mildew resistant, cracking resistant and worm damage resistant, strong in modifiability, good in stability and anti-skid.

Description

technical field [0001] The invention relates to a plastic-wood composite material, in particular to an online embossed high-strength anti-slip plastic-wood composite material plate and a preparation method thereof. Background technique [0002] People have an affinity for wood, but wood itself also has shortcomings, such as easy shrinkage and cracking, easy deformation when exposed to water, easy to mold when exposed to moisture, and easy to burn when exposed to fire. If it is used indoors, toxic and harmful gases such as formaldehyde and VOC will also damage the Indoor pollution. It is very necessary to invent a kind of novel plate to replace timber. Among them, wood powder, agricultural straw powder and other plant fibers and plastics are the main raw materials, and wood-plastic composite materials processed by advanced technology are one of them. [0003] Wood-plastic composite materials have a wide range of raw materials, are environmentally friendly, renewable, and re...

Problems solved by technology

Although this operation can leave lines on the surface of the plastic-wood board, there are also shortcomings. The most prominent two points are, first, the rolling pressure of the roller must be very high, otherwise no clear lines will be left on the surface of the plastic-wood board. Therefore, the pressure roller and its bracket used must be able to withstand high pressure, and the material performance requirements for the pressure roller and its bracket are relatively high, and the production cost of the pressure roller and its bracket is relatively high; second, the plastic wood board has been cooled and shaped , Although the external force of the pressure roller can produce lines on the surface of the plastic wood board, the stability of the lines is poor. After the pressure roller is removed under high pressure, the lines produced are easily deformed and recovered due to relaxation. After a period of use , the texture gradually blurs, or even disappears, losing its decorative and anti-slip effects
