Problems solved by technology

[0003] (1) Solid wood flooring, the resources are becoming more and more scarce, the price is high, the physical properties are poor, the installation and maintenance are complicated, and the non-combustibility is poor;
[0004] (2) Solid wood composite flooring has poor non-combustibility and high price. When the cost is reduced, the adhesive may have free formaldehyde;
[0005] (3) Laminate flooring reduces texture and comfort;
[0006] (4) The performance and comfort of bamboo flooring are average, the installation and maintenance are more complicated, the service life is short due to mildew, and the non-combustibility is poor;
[0007] (5) PVC flooring is mainly a by-product of the petroleum industry, with average texture and comfort. It is widely used in public places, and its non-combustibility is not the highest;
[0008] (6) Traditional floors are rarely used in ground radiant heating environments. On the one hand, the problem of deformation, discoloration, cracking, and abnormal noise has not been completely resolved; key performance

Abstract

The invention relates to the field of composite building decoration materials, particularly to a novel magnesium-based cementing material and a magnesium-based cementing material floor preparation method, wherein the raw materials of the magnesium-based cementing material comprise, by weight, 100 parts of magnesium oxide powder, 15-25 parts of sericite powder, 6-7 parts of an Al2O3 filler, 25-32 parts of bamboo chips, 5-7 parts of perlite, 0.2-1 part of citric acid, 0.5-1 part of a composite phosphate, and 45-60 parts of a composite sulfate. According to the present invention, the magnesium-based cementing material floor has the substantially improved physical property, can solve the disadvantages of fire intolerance, and easy deformation, cracking and discoloration after contacting of water and heat sources of the traditional floor, has advantages of simple installation, simple maintenance, heat storage, temperature adjustment, humidity adjustment and the like, and has the improved utilization rate in the case of the increasingly-reduced forest resources.

Description

technical field [0001] The invention relates to the field of composite building decoration materials, in particular to a novel magnesia cementitious material and a preparation method for the magnesia cementitious material floor. Background technique [0002] Commonly used floors include wood flooring and PVC flooring. Wooden flooring is mainly divided into solid wood flooring, solid wood composite flooring, laminate flooring, and bamboo flooring. Advantages of flooring, and excellent physical properties; Laminate flooring is wear-resistant and easy to take care of; Bamboo flooring is beautiful and practical, saving wood resources; PVC flooring is more wear-resistant, stain-resistant, environmentally friendly and non-toxic, etc., but the existing flooring products are also different to varying degrees There are the following technical defects: [0003] (1) Solid wood flooring, the resources are becoming more and more scarce, the price is high, the physical properties are poo...
