Problems solved by technology

[0003] Traditional bathtub walls generally use the same acrylic fiberglass composite material or wooden material as the inner wall of the bathtub. The acrylic glass fiber composite bathtub wall is very heavy and is easily damaged during transportation. It takes up a lot of space during transportation or storage and is difficult to place; and Wooden material is used as the bathtub wall, which is in contact with water for a long time, and the wood is easy to mold and deform, so it cannot be used for a long time, which will reduce the service life of the bathtub

Abstract

The invention discloses a wood-plastic composite material and bathtub wall plates using the same. The wood-plastic composite material comprises, by weight, 30-37 parts of polyethylene, 40-43 parts ofwood flour, 6-10 parts of activated calcium carbonate, 0.5-3 parts of plasticizers, 0.8-3.6 parts of antioxidant, 1-3 parts of bentonite, 1-2.5 parts of calcium stabilizers, 0.4-0.7 parts of foaming stabilizer zinc stearate, 0.5-3 parts of polyamide, 0.2-0.4 part of sodium hexametaphosphate and 0.1-0.24 parts of ultraviolet light absorbers. The wood-plastic composite material is simple in preparation method, wide in source, low in cost, good in environmental friendliness, the wood-plastic composite material serves as the bathtub wall plates, transportation is convenient, assembly can be achieved according to requirements, breaking strength is high, temperature is resistant, the wood-plastic composite material cannot deform when being used for a long time, the wood-plastic composite material has good appearance of wood materials and is applied to bathtub wall plates of outdoor bathtubs.

Description

technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to a wood-plastic composite material and a bathtub wall plate using the wood-plastic composite material. Background technique [0002] Thermoplastic wood-plastic composite material is a thermoplastic material made of wood fiber and plastic fiber by hot pressing. It combines the advantages of wood and plastic. Advantages such as recycling. [0003] Traditional bathtub walls generally use the same acrylic fiberglass composite material or wooden material as the inner wall of the bathtub. The acrylic glass fiber composite bathtub wall is very heavy and is easily damaged during transportation. It takes up a lot of space during transportation or storage and is difficult to place; and Wooden material is used as the bathtub wall, which is in contact with water for a long time, and the wood is easy to mold and deform, so it cannot be used for a long time, which will reduce th...
