Thermal insulation plastic-wood composite material plate and preparation method thereof

Abstract

The invention relates to a thermal insulation plastic-wood composite material plate and a preparation method thereof. The plate is suitable for manufacturing wallboards, apron boards, doors, window frames, auxiliary windows and the like. A thermal insulation plastic-wood core layer plate is arranged in the middle, and a foaming plastic-wood shell layer coating sleeve is arranged on the periphery.The thermal insulation plastic-wood core layer plate is formed by a material flow formed by uniformly mixing high-density polyethylene, maleic anhydride grafted polyethylene, wood flour, modified expanded perlite particles, zinc oxide and zinc stearate. The foamed plastic-wood shell layer coating sleeve is formed by a material flow formed by uniformly mixing polyvinyl chloride, modified wood powder, polyurethane powder, hydrogenated polybutadiene-g-polymethyl methacrylate, oily hollow glass beads, terpene resin, zinc stearate and oxidized polyethylene. The plate has the advantages of convenient production, strong production continuity, high efficiency, water resistance, corrosion resistance, worm damage resistance, no cracking, no aging, no color difference, no paint shedding in the use process, no formaldehyde or other toxic VOCs, light weight, heat insulation, heat preservation, more energy saving after use and the like.

Description

Technical field [0001] The invention relates to a plastic-wood composite material, in particular to a thermal insulation plastic-wood composite material board and a preparation method thereof. A thermal insulation plastic-wood composite material board is suitable for making wall panels, skirt panels, doors, window frames, auxiliary windows and the like. Background technique [0002] Sheets have been widely used in interior decoration and construction. Traditionally, these boards are generally made of wood, particle board, metal, stone, and resin materials. The use of these traditional materials to make boards has certain limitations, such as: the waterproof and anti-corrosion properties of boards made of wooden materials Poor, easy to be eroded by termites, and the surface paint layer is easy to fall off. Trees need to be cut down during the production process, which is not conducive to water and soil conservation and environmental protection. Particle board boards, such as part...

Problems solved by technology

Traditionally, these boards are generally made of wood, particle board, metal, stone, and resin materials. There are certain limitations in the use of these traditional materials to make boards, such as: the waterproof and anti-corrosion performance of boards made of wood materials Poor, easy to be eroded by termites, the surface paint layer is easy to fall off, trees need to be cut down in the production process, which is not conducive to water and soil conservation and environmental protection, etc. Particle boards, such as particle boards, composite floors, etc., have low strength, are easily broken, and are easily damaged by water Swelling, may contain formaldehyde or other toxic VOC, etc.; metal plates are bulky, difficult to manufacture, poor in modifiability, poor heat insulation effect, etc.; stone plates are fragile, poor in touch, difficult to form, and low in production efficiency , poor heat insulation effect, etc.; resinous boards are easy to deform, poor in modifiability, high in cost, and easy to cause environmental pollution in the production process, etc.
