Problems solved by technology

However, with the intensification of air pollution, acid rain is becoming more and more harmful. The service life of existing wood-plastic composite materials is reduced due to acid and alkali corrosion, and the floor damaged by acid rain corrosion becomes waste garbage, polluting the urban environment and affecting the appearance of the city. cityscape

Abstract

The invention discloses a wood plastic floor resistant to acid and alkali corrosion and a production technology thereof, and belongs to the technical field of construction materials. The wood plastic floor is prepared from the following raw materials in parts by weight: 20 to 40 parts of waste and old PVC aggregate, 3 to 8 parts of PVC plastic particle, 40 to 70 parts of waste and old wood powder or fiber powder, 5 to 10 parts of active calcium carbonate, 1 to 3 parts of filler, 5 to 10 parts of processing aid, 1 to 5 parts of anti-aging auxiliary agent, 0.1 to 0.15 part of copper powder, 0.01 to 0.02 part of molybdenum disulfide, and 5 to 10 parts of PTFE pellet. The raw materials mentioned above are subjected to steps of granulating, mixing, extruding, and moulding to produce the wood plastic floor. Compared with the conventional wood plastic floors, the provided wood plastic floor has the advantages of good mechanical properties, strong performance on resisting acid and alkali corrosion, and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to an acid and alkali corrosion-resistant wood-plastic floor and a production process thereof. Background technique [0002] Wood-plastic composite material is a new type of material made of wood and plastic as raw materials, adding modification additives such as coupling agent, and making through different processing methods such as hot pressing compounding and melt extrusion. This material can not only give full play to the advantages of each component in the material, overcome the use limitations caused by the low strength of wood, large variability, etc., but also overcome the use defects of organic materials such as low elastic modulus, and can improve the quality of the material. Physical and chemical properties. my country is a country with relatively poor forest resources, and the supply of wood is facing a huge gap. At the same time, the problem of "white pollut...
