However, the surface of the glass sprayed with anti-mold liquid will leave fog marks, and glass companies and users are not easy to accept this protection method; although the anti-mold film has a better protective effect on glass packaging, but the price is high, which greatly increases the cost of glass.
[0003] In addition, pressure-resistant glass does not have the function of heat resistance and fire prevention. Once a fire breaks out, the pressure-resistant glass will break in a short time, causing the fire to spread, and people's life safety and property are seriously threatened.
At present, the fire prevention method of glass is mainly made of two or more layers of single glass sandwiched with fireproof materials, but after a long time of use, mildew, yellowing and foaming will appear The reason is that the long-term storage will cause glue flow, which will affect the service life of the pressure-resistant glass. Moreover, although most of the glass meets the fireproof effect, it cannot guarantee the integrity of the glass when it encounters a fire. Once the glass bursts, it will also promote Flame burns, based on this, we invented a glass that is fireproof, mildew-proof, and heat-shock-resistant

Abstract
The invention discloses a fireproof and pressure-resistant glass and a preparation method thereof, and relates to the technical field of glass. The preparation method comprises the following steps: modifying a raw material, and carrying out graded vacuumizing, pressurizing and founding to remove bubbles; then, carrying out heating treatment by utilizing induction plasma, pulse current and electromagnetic induction to form a grid structure, so as to improve the mechanical property and thermal shock resistance of the glass; performing compression molding, coating with a self-made fireproof coating, and pressurizing again to reduce a gap, so as to obtain the glass. The silicon dioxide is modified by using the hydroxyundecanol acetate and the carbobenzoxy nitrile, so that the breeding of glass microorganisms is effectively reduced, the moisture adsorbed on the surface of the glass is reduced, and the glass has a mildew-proof effect; AND according to the self-made fireproof coating, dendritic charcoal microspheres are supported by calcium carbonate, walnut shell powder and fatty alcohol glyceryl sulfonate through electric spark sintering, differential pressure flash evaporation, microwaves and an electrostatic field, so that the glass has fireproof and thermal shock resistant effects. The fireproof AND pressure-resistant glass prepared by the invention has fireproof, mildew-proof and thermal shock-resistant effects.
Description
technical field [0001] The invention relates to the technical field of glass, in particular to fireproof and pressure-resistant glass and a preparation method thereof. Background technique [0002] Pressure-resistant glass refers to a special glass whose overall structure remains intact and does not break under a certain pressure impact. Pressure-resistant glass is made of special materials, and its compressive performance is 10 to 20 times that of ordinary glass. It is an ideal window material for high-pressure containers, valves, pipes, liquid level gauges, and instruments. It is widely used in chemical industry, petroleum, electric power, and pharmaceuticals. , machinery manufacturing and other fields. Because pressure-resistant glass is often used in a liquid environment, under the influence of certain temperature, humidity, and chemical atmosphere, pollution-induced mildew will occur, which greatly affects the quality of the glass, and sometimes causes the entire equip...
