Abstract

The invention relates to a stone etching solution and a preparation method thereof, and belongs to the technical field of stone processing. The preparation method comprises the following steps modifying corncobs through a pre-emulsification technology in emulsion polymerization to prepare alkali-treated corncob powder grafted acrylate emulsion; then compounding the alkali-treated corncob powder grafted acrylate emulsion with a corrosion solution; diluting with water to prepare the stone etching solution. According to the stone etching solution and the preparation method thereof, etched surfaces of stones are rapidly wetted, small-particle dust covers the stones while the stones are corroded and softened, and films are formed on the surfaces of the stones so as to effectively prevent the small-particle dust in subsequent treatment from flying off, reduce the dust rising rate and reduce damages, caused by the dust in a stone etching process, to workers; the stone etching solution and thepreparation method thereof have the advantages of high working efficiency, simple technology, labor saving and time saving, and raw material saving and have a wide application prospect.

Description

technical field [0001] The invention relates to a stone etching solution and a preparation method thereof, belonging to the technical field of stone processing. Background technique [0002] Stone corrosion carving is a new carving process developed in recent years. It uses chemical corrosion liquid to react with stone to achieve the purpose of carving. Compared with the traditional mechanical engraving method, corrosion engraving has the advantages of low labor intensity and high engraving speed, especially for complex and difficult engravings that cannot be solved by hand. The shortcomings of corrosion engraving are mainly manifested in the poor performance of three-dimensional engraving. In addition, due to the wide variety of stone types, components, and properties, the corrosive agents selected are also very different, which increases the difficulty of its application. However, with the continuous improvement of etching technology, it will show the incomparable super...
