Problems solved by technology

Although the fireproof glass prepared by this method improves the fireproof performance of the glass to a certain extent, the adhesion of the fireproof liquid is low, which makes the compatibility between the fireproof liquid layer and the glass poor, and often occurs during long-term use. The problems of anti-detachment and anti-aging properties of glass affect the fireproof performance. With the continuous development of the construction industry, the utilization rate of fireproof glass is increasing. It is required that the fireproof liquid can ensure that the glass still has the fire protection under long-term use conditions. good fire performance

Embodiment 1

[0056] 1. Prepare fireproof liquid

[0057] 1-1) Prepare raw materials according to the following weight ratio (g)

[0058]

[0059] 1-2) Pour the raw materials potassium nitrate, cesium nitrate, Swiss seven-eight, methacrylic acid, acetone, and table salt into a plastic container filled with water in sequence, stir with an electric stirrer, and perform mixing treatment, wherein the stirring rate is 120rpm ( Usually 60-120rpm); stirring time is 1.5h;

[0060] 1-3) Stir and mix the mixed solution for 1.5 hours, and place it still at a temperature of 25° C. to allow it to fully fuse with each other and undergo a chemical reaction. After standing for 48 hours, the glass fireproof composition liquid is obtained.

[0061] 2. Replacement treatment

[0062] 2-1) Evenly spray the fireproof composition for glass on the surface of float glass with a thickness of 12mm, spray evenly on both sides of the glass, spray 12g (usually 10-15g) fireproof composition per square meter of glass...

Embodiment 2

[0080] 1. Prepare fireproof liquid

[0081] Same as Example 1

[0082] 2. Replacement treatment

[0083] Except for the thickness of the float glass which is 8mm, the spraying amount of the fireproof composition is 10g / m 2 , except that all the other are identical with embodiment 1;

[0084] 3. Cleaning and drying

[0085] Same as Example 1

[0086] 4. Tempering treatment

[0087] Except the preheating temperature in step 4-1) is 475°C; the glass reciprocates in the furnace at a speed of 80-300mm / s, and the preheating is 260s; the top hot air convection intensity: within the convection heating time interval of 1% to 50% (that is, from the time when the glass enters the tempering furnace to the 130s after entering), the convective pressure intensity of the top hot air is 3.6bar; the convective pressure of the top hot air is 50% to 70% of the convective heating time interval (that is, from the 130s to 182s after entering the tempering furnace). The strength is uniformly re...

Abstract

The invention discloses a method for preparing fireproof glass. The method of the invention includes performing a tempering treatment on the surface of the glass after using a fireproof liquid. The fireproof glass prepared by the method of the invention has good high temperature resistance, high fire resistance, and It has strong impact performance, excellent mechanical properties, and high safety in use, providing an effective time guarantee for human escape and fire extinguishing in a fire environment; moreover, the method of the invention is simple to operate, and the preparation process conditions are mild, which reduces the production cost of fireproof glass .

Description

technical field [0001] The invention relates to a method for preparing glass, in particular to a method for preparing fireproof glass, and belongs to the field of fireproof glass production. Background technique [0002] Fire-resistant glass is a special glass that can maintain its integrity in the prescribed fire-resistant test. Its role in fire prevention is mainly to control the spread of fire or to isolate smoke. It is a measure-type fireproof material. Performance is evaluated. It is a special glass that has been processed and treated by a special process and can maintain its integrity and heat insulation in the specified fire resistance test. The original glass of fireproof glass can be made of float flat glass, toughened glass, and the composite fireproof glass can also be made of single piece of fireproof glass. [0003] There are five main types of fireproof glass, which are laminated composite fireproof glass, wire fireproof glass, special fireproof glass, hollow...
