Problems solved by technology

However, the existing wood-plastic panels have high requirements for raw materials, and recycled waste plastics cannot be used, and new plastics are required, so the cost is relatively high
In addition, the existing wood-plastic door panel molding process is complicated, and the formed door panel has poor waterproof, moisture-proof and corrosion resistance. After a certain period of use, the sheet will crack, and the strength and toughness are low, which is difficult to meet the needs of people today.

Abstract

The invention discloses a dampproof and anti-cracking PVC wood plastic door plank and a preparation method thereof, and relates to the technical field of novel energy-saving door plank production. Thewood plastic door plank is prepared from the following raw materials of PVC resin powder, enveloped calcium silicon powder, chlorcosane, ardealite, aerated aluminum powder, aluminum silicate fiber, lignocellulose, a calcium-zinc stabilizer, a foaming agent, a foam stabilizer, a dry strength agent, a plasticizer and a coupling agent. The preparation method of the PVC wood plastic door plank comprises the steps of uniform mixing of the raw materials, extrusion, modeling, cutting, engraving, deburring, transfer printing, stoving varnish, solidifying, inspecting and the like. The PVC wood plasticdoor plank is simple in preparation technology and low in raw material cost, has the properties of environmental protection, watertightness and moisture resistance, corrosion crack resistance and high strength and toughness, and is long in service life and wide in application range.

Description

technical field [0001] The invention relates to the technical field of production of new energy-saving door panels, in particular to a moisture-proof and crack-proof PVC wood-plastic door panel and a preparation method thereof. Background technique [0002] With the development of society, composite materials are widely used in various industries. Among them, wood-plastic material is a kind of composite material. Because wood-plastic has both the texture of plastic and wood, it has become an outdoor building material with excellent performance and durability; it can also replace wooden components used in ports, docks, etc., and can also be used to replace wood to make various packaging materials , pallets, warehouse backing boards, etc. are too numerous to mention, and they are extremely versatile. Wood-plastic board, which combines many advantages of plant fiber and plastic polymer materials, can replace wood in large quantities, and can effectively alleviate the contradi...
