Abstract

The invention provides a stone treatment agent which consists of hydrogen chloride, hydrogen fluoride, hydrogen peroxide, sulfuric acid, water, a corrosion inhibitor and water. The preparation method comprises the following steps: treating the liquid containing the components by using a decolorizing agent, thereby obtaining the stone treatment agent product, wherein the hydrogen chloride accounts for 5-20 mass percent, the hydrogen fluoride accounts for 10-20 mass percent, the hydrogen peroxide accounts for 10-30 mass percent, the corrosion inhibitor accounts for 5-15 mass percent, the sulfuric acid accounts for 1-10 mass percent, and the rest is water; and the use amount of the decolorizing agent is 10-30Kg/ton of the liquid. According to the stone treatment agent provided by the invention, the treatment operations in aspects of removing impurities on the stone surface, removing stains and impurities on the cutting surface and the polishing surface, flattening the surface, engraving the stones can be effectively realized, a phenomenon that a layer of colored oxides is attached to the surface of the stone is avoided, the oxides are easy to clean and remove, and the subsequent treatment difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a natural stone treatment agent. Background technique [0002] At present, with the development of the construction industry, the application of stone in decoration and sculpture has also increased rapidly. Common surface processing methods for natural stone include mechanical polishing, matte treatment, rough grinding, and machine cutting. Pickling is a chemical treatment method, which uses strong acid to corrode the surface of the stone to make it have small corrosion marks, and the appearance is more rustic than the polished surface. Most stones can be pickled, but the most common are marble and limestone. Acid washing is also a way to soften the luster of granite. [0003] The current chemical treatment method for stone is still the traditional nitric acid and concentrated sulfuric acid treatment. After this method, there is a layer of colored oxides attached ...
