Embodiment 1

[0048] A fireproofing liquid comprises the following components in parts by weight: 10 parts of potassium nitrate, 1.5 parts of potassium fluoride, 5 parts of potassium bicarbonate, 1.5 parts of rubidium nitrate, 1.5 parts of rubidium carbonate and 80 parts of water.

[0049] A preparation method of fireproof glass, comprising the steps of:

[0050] Acid solution pretreatment: Put the glass in a hydrofluoric acid solution with a concentration of 7%, soak it at room temperature for 1-2 minutes, take out the glass, clean it with deionized water, and dry it for later use.

[0051] Place the glass upright on the glass rack, and spray the above-mentioned fireproof liquid on the glass surface until the glass surface is uniformly foggy.

[0052] Standing for one time: place the glass at room temperature for 40min.

[0053] Second standing: place the glass at a temperature of 160°C for 40 minutes.

[0054] Cleaning: Clean the glass again after taking it out.

[0055] Physical tempe...

Embodiment 2

[0057] A fireproof liquid, which comprises the following components in parts by weight: 15 parts of potassium nitrate, 2 parts of potassium fluoride, 3 parts of potassium hydroxide, 2 parts of rubidium nitrate and 65 parts of water.

[0058] The preparation method of the fireproof glass in Example 2 is basically the same as that of Example 1, the difference being that the concentration of the hydrofluoric acid solution is: 9%; the time of standing for one time is 90min; the temperature of standing for the second time is 150°C Place it at 650°C for 30 minutes; temper it at 650°C for 5 minutes.

Embodiment 3

[0060] A fireproof liquid, which comprises the following components in parts by weight: 20 parts of potassium nitrate, 1 part of potassium fluoride, 2 parts of potassium acetate, 2 parts of potassium bicarbonate, 2.5 parts of rubidium carbonate and 72 parts of water.

[0061] The preparation method of the fireproof glass in Example 3 is basically the same as that in Example 1, except that the concentration of the hydrofluoric acid solution is 8%;

Abstract

The invention discloses fireproof liquid, fireproof glass and a preparation method of the fireproof glass. The fireproof liquid comprises potassium nitrate, potassium fluoride, an alkaline additive, rubidium salt and water. According to the fireproof liquid, potassium nitrate serves as a main agent, potassium fluoride, an alkaline auxiliary agent and rubidium salt serve as accelerators for assisting exchange reaction, and the fireproof liquid is sprayed to the surface of glass so that an exchange layer can be formed on the surface of the glass. According to the preparation method of the fireproof glass, the fireproof liquid is directly sprayed on the surface of glass, and secondary standing is carried out. Compared with an existing salt bath method, the replacement reaction time is greatly shortened, a potassium ion exchange layer of 30-40 microns is formed on the surface layer of the prepared fireproof glass, the Vickers hardness is larger than 710 kg.mm<-2>, the surface stress is larger than 480 mPa, the bending strength is larger than 400 mPa, the fire endurance grade is 2.00 h, and the light transmittance is good.

Description

technical field [0001] The invention relates to the technical field of fireproof liquid, glass and preparation methods, in particular to a fireproof liquid, fireproof glass and a preparation method thereof. Background technique [0002] With the improvement of people's awareness of fire prevention, the application of fireproof glass in buildings is becoming more and more extensive, and the requirements for the weight, quality and fireproof level of fireproof glass are also getting higher and higher. Traditional composite fireproof glass is used in several It is formed by filling organic matter between pieces of glass, which is bulky and poor in light transmission. After a long time in the sun, it is easy to weather; or pouring inorganic gel or organic gel fireproof liquid between several pieces of glass, after curing Fireproof glass is formed, but the inorganic / organic gel is prone to bubbles during the curing process, and the bubbles not only affect the fireproof ability, b...
