Problems solved by technology

Although this patent solves the problems of phosphogypsum pulverization and other problems, the preparation method of the imitation marble floor disclosed by it is complicated and costly. The activation reaction of phosphogypsum is realized by quicklime, and the activation degree and solidification performance are improved slowly and the effect is not obvious. , the overall improvement of imitation marble substrate is not enough

Embodiment 1

[0028] The preparation of phosphogypsum-based marble-like high-strength architectural decorative boards, the steps are as follows:

[0029] a. Grinding plant ash into nano-level fine powder with a particle size of 10-100 nm using a nano-grinding machine, and dispersing it in a fluidized device, the fluidized device includes at least one fluidized bed and a wall arranged on the fluidized bed The internal ice water circulation system is fed with water vapor at a temperature of 130°C, so that the plant ash fine powder is in full contact with the water vapor, and soaked in the water after the water vapor has condensed to form a leachate;

[0030] b. Simultaneously spray low-temperature rice husk ash with a temperature of 15° C. into the leachate prepared in step a, stir, mix evenly, quickly freeze and form, and pulverize, so that the pores on the surface of the rice husk ash are loaded with plant ash fine powder to obtain a composite powder;

[0031] c. Add 20 parts by weight of t...

Abstract

The invention belongs to the technical field of imitation-marble building material preparing, and particularly relates to a phosphogypsum-based imitation-marble high-strength architectural decorationplate and a preparing method. According to the phosphogypsum-based imitation-marble high-strength architectural decoration plate and the preparing method thereof, plant ash and lime are efficiently and firmly adsorbed through a porous structure of low-temperature rice husk ash, the obtained product is evenly dispersed for neutralizing treating phosphogypsum, the sodium content and the content of soluble impurities in the phosphogypsum are further controlled, the solidification performance of the phosphogypsum is thus promoted, the strength of a phosphogypsum base material is enhanced, and thedefect that as the sodium content is over high, the pulverization phenomenon appears on the phosphogypsum surface, and the strength of the phosphogypsum base material is poor is overcome; by combiningwith coating of a simulation coating again, the imitation-marble-effect morphology with good dirt resistance, high elasticity, high self-cleaning performance and excellent weather resistance can be formed on a surface layer, and the performance of the phosphogypsum base material is improved accordingly; meanwhile, raw materials such as phosphogypsum, coal ash, yellow phosphorus slag and waste textile fibers are used, pollution on the environment is reduced, radioactivity is avoided, the preparing method is simple, ingredients are low, and the operability is high.

Description

technical field [0001] The invention belongs to the technical field of preparation of stone-like building materials, and in particular relates to a phosphogypsum-based high-strength marble-like building decoration plate and a preparation method thereof. Background technique [0002] In recent years, the growth momentum of the decoration market has always been strong, but the construction and decoration industry is a rapidly developing and updating industry. Among them, exterior wall decoration is one of the important contents of architectural decoration. Its purpose is to improve the ability of the wall to resist the invasion and damage of various factors in nature such as dust, rain, snow, freezing, and sunlight, and to meet the requirements of the wall structure together. Insulation and exterior wall decoration are one of the important contents of architectural decoration. Its purpose is to improve the ability of the wall to resist the invasion and damage of various factor...
