[0051] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer are used. Where the manufacturer of the reagents or instruments is not specified, all are conventional products that can be purchased commercially.

[0052] The formula of the glass bottle according to the embodiment of the present invention and the preparation method thereof are described in detail below.

[0053] An embodiment of the present invention provides a formula for a glass bottle, comprising a plurality of raw materials, including, by weight, 20-30 parts silicate, 10-20 parts borate, 5-15 parts aluminate, 10-20 parts carbonate, 5-14 parts tin salt, 2-9 parts titanium salt, 10-20 parts oxide, 5-10 parts chloride, 12-15 parts basalt fiber, and 4-9 parts other auxiliary components. It should be noted that, in the embodiment of the present invention, by rationally configuring the tin salt, titanium salt, oxide, chloride, and basalt fiber in a certain proportion within the silicate, borate, aluminate, and carbonate, the glass bottle simultaneously exhibits excellent heat resistance, mechanical strength, and thermal insulation properties. Furthermore, by rationally configuring other auxiliary components, such as rare earth metal salts, clarifiers, and fluxes, the glass bottle further enhances its heat resistance and mechanical strength while maintaining its transparency and chemical stability, while also reducing the difficulty of its preparation process.

[0054] Furthermore, in preferred embodiments of the present invention, the oxides are sodium oxide, barium oxide, and / or magnesium oxide, and the chlorides are sodium chloride and / or potassium chloride. It should be noted that in the glass bottle formulations provided in the embodiments of the present invention, the oxides are primarily used to lower the softening point of the glass and enhance its stability and mechanical strength. Furthermore, the chlorides primarily serve to lower the melting point of the glass and can also react with certain components in the glass (such as oxides) to form low-melting-point compounds, facilitating the processing and molding of the glass. Furthermore, the chlorides can also improve the tensile strength and corrosion resistance of the glass.

[0055] More specifically, in a preferred embodiment of the present invention, the tin salt comprises at least one of tin sulfate, stannous sulfate, and stannous chloride. It should be noted that the addition of a tin salt in a certain proportion to glass primarily functions to form a network structure in the form of tin dioxide within the glass, thereby increasing the strength and stability of the glass. It also improves the glass's weather resistance and heat resistance, imparting excellent light transmittance, UV resistance, and thermal insulation properties. Furthermore, the tin salt enhances the chemical stability of the glass, preventing oxidation and mold growth on the surface of glass products, thereby extending the service life of the glass.

[0056] Furthermore, in a preferred embodiment of the present invention, the multiple raw materials preferably include, by weight, 25-28 parts silicate, 14-19 parts borate, 9-12 parts aluminate, 15-20 parts carbonate, 5-10 parts tin salt, 4-9 parts titanium salt, 10-16 parts oxide, 5-9 parts chloride, 14-15 parts basalt fiber, and 4-6 parts other auxiliary components. It should be noted that the raw materials provided according to this preferred embodiment have good compatibility and synergistic effects, resulting in the glass having superior heat resistance, thermal insulation, chemical stability, and mechanical strength.

[0057] More specifically, in a preferred embodiment of the present invention, the titanium salt is sodium titanate and / or potassium titanate. It should be noted that adding titanium salt to the formula of the glass bottle can react with certain components in the glass to make the glass have anti-ultraviolet and infrared properties, improve the weather resistance and heat resistance of the glass, and at the same time enhance the chemical stability of the glass, prevent the surface of the glass product from oxidation and mold, thereby further improving the service life of the glass. Specifically, the titanium salt reacts with the silicate to form a titanium silicate complex, which makes the glass have anti-ultraviolet and infrared properties and improves the weather resistance and heat resistance of the glass; the titanium salt reacts with the tin salt to form titanium stannate, which improves the chemical stability of the glass, prevents the surface of the glass product from oxidation and mold, and improves the service life of the glass; the titanium salt reacts with the barium oxide to form barium titanate, which can enhance the impact resistance of the glass and improve the strength and hardness of the glass.

[0058] Furthermore, in a preferred embodiment of the present invention, the other auxiliary components include at least a rare earth metal salt, a clarifier, and a flux. Specifically, preferably, the rare earth metal salt is at least one of cerium nitrate and lanthanum nitrate, the clarifier is at least one of white arsenic, sodium sulfate, and sodium nitrate, and the flux is cryolite, sodium fluorosilicate, and / or tin phosphide. Furthermore, the ratio of the rare earth metal salt, the clarifier, and the flux is 1:2:2 by weight. It should be noted that in this embodiment of the present invention, through the rational combination of the other auxiliary components, such as the rare earth metal salt, the clarifier, and the flux, the heat resistance and mechanical strength of the glass bottle are further enhanced while maintaining its transparency and chemical stability, while also reducing the difficulty of its production process. It is important to emphasize that the small amount of rare earth metal salt in the other auxiliary components not only acts as a decolorizer, namely, after decolorizing the glass, making it more translucent, bright, and crystal white, but also improves the strength and heat resistance of the glass, preventing it from discoloring even under long-term exposure to the sun.

[0059] An embodiment of the present invention further provides a method for preparing a glass bottle, which comprises the following steps:

[0060] S1. Mix, by weight, 20-30 parts of silicate, 10-20 parts of borate, 5-15 parts of aluminate, 10-20 parts of carbonate, 5-14 parts of tin salt, 2-9 parts of titanium salt, 10-20 parts of oxide, 5-10 parts of chloride, 12-15 parts of basalt fiber, and 4-9 parts of other auxiliary components to obtain a raw material mixture. It should be noted that in the embodiments of the present invention, nitrogen gas is introduced during the high-temperature melting process for protection to suppress the generation of impurity oxides, thereby improving the quality of the glass bottles while also protecting the environment and reducing pollution.

[0061] S2. Melting the raw material mixture at a high temperature to form molten glass. It should be noted that the high temperature melting temperature is 1240-1390°C. The reason for limiting the high temperature melting temperature in the embodiments of the present invention is that temperature control during the melting process is crucial to the quality and performance of the final glass. Specifically, by controlling the melting temperature, bubbles, cracks, or other defects in the final glass can be avoided during the melting process of the raw material mixture, the raw materials can be fully mixed and homogenized during the homogenization process of the raw material mixture, and bubbles and impurities can be completely removed during the clarification process of the raw material mixture.

[0062] S3. Form the molten glass into a glass bottle and perform annealing treatment and room temperature cooling. Particularly, the temperature during the process of forming the molten glass into a glass bottle is 220-340°C; during the annealing treatment, the temperature is 310-390°C, and the cooling rate during the annealing treatment is 18°C ​​per hour. It should be noted that, in the embodiment of the present invention, the internal stress in the glass can be eliminated through annealing treatment, thereby preventing the deformation and cracking of the glass bottle products during processing and use, and improving the strength, heat resistance and stability of the glass; and, in the embodiment of the present invention, the full annealing method is adopted to limit the cooling rate of annealing, which can not only eliminate the internal stress in the glass, but also avoid the generation of new internal stress.

[0063] It should be further explained that in order to give full play to the effect of the basalt fiber in the glass bottle formula of the present application on improving the heat resistance, heat insulation and mechanical strength of the glass bottle, in a preferred embodiment of the present invention, the basalt fiber is prepared by the following method:

[0064] 1) crushing the basalt rock to obtain basalt fine powder with a particle size of 1-5 microns;

[0065] 2) adding the basalt fine powder into a reaction kettle containing a sodium hydroxide solution with a mass percentage concentration of 10% to 30%, and performing a hydrothermal reaction at a temperature of 150-250° C. for 1-3 hours;

[0066] 3) centrifuging the reaction solution at a speed of 3000-5000 rpm to obtain a first basalt fiber matrix;

[0067] 4) drying the first basalt fiber matrix to obtain a second basalt fiber matrix, wherein the drying is performed at a temperature of 100-200° C. for 1-3 hours;

[0068] 5) The dried basalt fiber second matrix is ​​subjected to surface treatment to obtain basalt fiber. The surface treatment is performed in an aqueous solution containing a silane coupling agent with a mass percentage concentration of 1% to 10%, and the treatment time is 1 to 3 minutes.
