Problems solved by technology

Although granite stone powder has the incomparable structural strength advantage of natural stone, it is difficult to be widely used in the field of decorative engineering. In addition, its processing technology is complicated and the maintenance conditions are harsh, so the processing cost is high, so the application field is limited.

preparation example Construction

[0028] A preparation method for preparing granite decorative plates by using granite sawing mud, comprising the following steps:

[0029] (1) Surface material configuration: The surface material is composed of the following materials by mass: PO42.5 white / ordinary Portland cement 90-110 parts, granite washed fine sand 50-130 parts, granite stone powder 10-30 parts, Fe3O4 magnetic 2-5 parts of iron ore powder, 1-3 parts of aluminum silicate, 0.5-10 parts of inorganic oxidation pigment;

[0030] (2) Forming of the surface layer material: select the surface layer material according to the proportion of step (1), after the above materials are fully mixed, add 20-30% clear water accounting for PO42.5 white / ordinary portland cement weight, and fully mix the material After the viscous paste is synthesized, it is poured into the mold for paving. The average thickness of the paving is not more than 3mm. After paving, the double vibrator platform is vibrated, and the vibrating time is n...

Abstract

The invention discloses a preparation method for preparing a granite decorative plate from granite sawing mud. The method comprises the steps of surface layer material preparation, surface layer material forming, base layer material preparation, base layer material forming, composite material secondary forming and product maintenance. The machine-made fine sand and stone powder produced by processing granite solid waste are adopted to replace quartz sand and quartz powder, and the product cost can be effectively reduced on the basis that granite sawing mud is massively applied and the environmental influence is eliminated; after the product is formed at a time, the product is free of cracks in appearance and deformation in structure, and is excellent in stability, and has the advantages ofhigh strength, high bending resistance, low water absorption, acid and alkali resistance, fire resistance, weather resistance and the like of an RPC composite material, all indexes are superior to those of natural stone, and the product service life reaches 50 years or longer.

Description

technical field [0001] The invention relates to the technical field of plate preparation, in particular to a preparation method for preparing granite decorative plates by using granite sawing mud. Background technique [0002] During the cutting process of natural granite, about 5% of sawing mud will be produced. Because these sawing mud contains chemicals such as coolants and suspending agents, and materials with a diameter of ≤75 μm account for more than 80% of its weight ratio, there is still no great success in China. Applying the mature technology of granite sawing mud, most of the sawing mud is dumped randomly, resulting in serious water pollution; at the same time, sawing mud powder has a certain cohesive force and is repeatable, even if it is plowed or applied with farmyard manure, it cannot be completely eliminated. In the soil, it will make the soil harden quickly, and the air permeability, moisture retention and internal structure of the soil will lead to damage, ...
