In order to achieve the purpose, the invention adopts the technical scheme that:

a method for manufacturing glass with a slush effect comprises the following steps:

1) Preparing a glass etching solution;

2) Covering and protecting the surface of the glass original sheet which does not need to be etched by using an instant protective film;

3) And cleaning one surface of the glass original sheet needing the etching of the ice effect by using deionized water, soaking the glass original sheet in the etching solution for 5-10 minutes in a wet state, and taking out the glass original sheet to obtain the etched glass.

Further, the glass etching solution is composed of the following raw materials in percentage by mass: NH ₄ HF ₂ 20-25%、NH ₄ F 8-15%、H ₂ SO ₄ 10-15%、 HNO ₃ 8-15%、CuSO ₄ 3-8%、ZnCL ₂ 3-5%、Na ₂ B ₄ O _7• 10H ₂ 0.5-0.8% of O, 4-6% of cane sugar and H ₂ O15-25%, and when in specific preparation, the H is ₂ SO ₄ Slowly adding into water to prevent splashing, cooling to normal temperature, sequentially adding other raw materials, fully stirring to supersaturated state, standing at room temperature, and aging for 24-72 hr.

Further, the etching glass in the step 3) is taken out of the etching solution and then washed by deionized water, and then the etching glass is naturally dried or baked.

Further, the room temperature is 20-25 ℃.

The invention has the advantages that: the invention adopts the immersion etching process to manufacture the glass with the slush effect, optimizes the components and the content of the formula of the etching solution special for the glass with the slush effect, mixes the proper surface active substance and the viscosity regulator, realizes the etching treatment on the surface of the soda-lime glass according to the proper formula proportion, forms the natural slush effect pattern on the surface of the glass, selects the proper etching raw material to prepare the etching solution according to a certain proportion, carries out the immersion etching treatment on the glass sheet, leads the surface of the glass to present the natural slush fantasy visual effect, and leads the glass product with the slush effect to have the excellent performances of reflecting light resistance, scratch resistance, dust resistance, fingerprint resistance and the like; the fluoride in the formula of the etching solution has an etching effect on glass, the shapes of frosted particles generated by reaction with the surface of the glass in acid solutions with different concentrations and different types are different, the frosted microcrystalline particles formed by complex chemical reaction belong to silicate complex polymers, and different crystal form effects of the frosted microcrystalline particles on the surface of the glass can be realized by adding different types of salt substances, so that the desired etching effect on the surface of the glass is realized ₂ B ₄ O ₇ •10H ₂ O belongs to a surface active substance and aims to promote the etching solution to realize uniform and consistent chemical reaction on the surface of the glass, and the purpose of adding the sucrose is to adjust the viscosity of the etching solution and keep the stability and the suspension effect of the supersaturated etching solution.
