Hemihydrate gypsum base material imitation wood floor and preparation method thereof

Abstract

The invention relates to the technical field of chemical building materials, in particular to a hemihydrate gypsum base material imitation wood floor and a preparation method thereof. By properly proportioning and designing raw materials such as hemihydrate gypsum, cement, a coagulation accelerator and the like, the quality of the hemihydrate gypsum is improved, the activity of the hemihydrate gypsum is improved, the toughness and plasticity of a product made from the hemihydrate gypsum are improved, the flexural and compressive strength of a base material made from the hemihydrate gypsum as a raw material is enhanced, the freeze-thaw resistance of a phosphogypsum product is improved, and the weather resistance and corrosion resistance of the phosphogypsum product are improved; by combination with control on technical parameters in a preparation process after the raw materials are properly proportioned, the compatibility of the hemihydrate gypsum, the cement, the coagulation accelerator, fibers and the like is relatively good, holes of the product are uniform in size, and the waterproof and dampproof performance and mechanical strength of the hemihydrate gypsum base material are improved.

Description

technical field [0001] The invention relates to the technical field of chemical building materials, in particular to a hemihydrate gypsum base material imitation wood floor and a preparation method thereof. Background technique [0002] Wood profiles are the main materials for indoor and outdoor furniture, pavement or decoration, but the growth cycle of wood is long, resources are few, and production costs are high. There are many products that use composite materials instead of wood on the market today. However, these composite materials simply cannot meet the needs of wood products, nor can they achieve the performance and quality of wood products. At present, wood-plastic composite materials are mainly used in the alternative production of wood panels. This is an environmentally friendly material that has the advantages of plant fibers and plastics and can cover all logs, plastics, plastic steel, aluminum alloys and other similar composites. The field of use of the mate...

AI Technical Summary

Problems solved by technology

However, the above-mentioned materials in the prior art are still difficult to meet the performance requirements of the wood itself, which leads to shorter service life and poorer quality of the wood materials used for lignified furniture, paving or decoration, and the performance of the products produced is relatively poor. Poor; especially poor corrosion resistance and weather resistance

[0003] At the same time, products made of hemihydrate gypsum have better thermal insulation performance, lighter product quality, and the obtained products have better corrosion resistance and weather resistance. However, there is currently no use of hemihydrate gypsum as a raw material to make imitation products. In addition, gypsum is also one of the wastes with a large stockpile in the world. These stockpiles will cause a large amount of environmental pollution and cause damage to large areas of land resources.
