A kind of phosphogypsum base material imitation marble floor and preparation method thereof

Abstract

The invention relates to the technical field of chemical engineering building materials and especially relates to a phosphogypsum base material marble-imitation floor and a preparation method thereof. By means of a proper mixing proportion of phosphogypsum, yellow phosphorus furnace slag, quick lime, a coagulant, glass fibers and cement with technical parameters during the matching process controlled, activation among the raw materials can be carried out accurately, and especially a strong activation is carried out during the mixing process between the phosphogypsum and the quick lime, thereby increasing the activity of the phosphogypsum and improving the performance of the phosphogypsum. In addition, by limitation and control of the contents of sodium and soluble impurities in the phosphogypsum, the phosphogypsum is improved in solidification performance and enhanced in strength, so that a defect of a poor strength of the phosphogypsum base material due to pulverization on the surface of the phosphogypsum due to excessive high content of sodium is avoided. Furthermore, by means of the combination of a marble-imitation coating for painting the phosphogypsum base material, the surface of the phosphogypsum base material has a marble-imitation appearance and the performances of the phosphogypsum base material are improved.

Description

technical field [0001] The invention relates to the technical field of chemical building materials, in particular to a phosphogypsum-based imitation marble floor and a preparation method thereof. Background technique [0002] The floor is usually a kind of floor tile designed when building on the indoor ground. The floor tile has the requirements of high flexural and compressive strength, strong wear resistance, strong weather resistance, and strong corrosion resistance. With the development, and the continuous demand for floor performance improvement, the requirements for the floor's thermal insulation performance, moisture absorption and corrosion resistance are also getting higher and higher. However, it is difficult for the floor in the prior art to meet the overall requirements of the above-mentioned technical problems, and the quality of the floor in the prior art is relatively heavy, it is also inconvenient to install the floor, and it consumes a lot of manpower; The...

Problems solved by technology

[0005] However, although the products made of phosphogypsum have the above-mentioned technical characteristics, they are still only used in the preparation process of some simple building materials, such as making them into hollow blocks, thermal insulation blocks, hollow bricks, thermal insulation bricks, etc. And so on, and then there is no need to design and manufacture it as a floor building; at the same time, imitation marble technology has been developed and changed around the world, and the process of imitating marble products is the process of painting the surface of the substrate, and this The process of painting paint varies with the type of paint and substrate, and the method of painting is different. Because phosphogypsum products are easily affected by sodium elements, crystal flowers are formed on the surface of phosphogypsum products, that is, pulverization. The process of making phosphogypsum as the base material is seriously affected, and the preparation technology of imitating products using phosphogypsum as the base material has not been reported, especially the technology of using phosphogypsum as the base material to imitate marble floors has not yet been reported.
