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

Abstract

The invention discloses a method for preparing fire-resistant glass. The method of the invention includes using a fire-proof liquid to perform a replacement reaction on the surface of the glass, and then performing a tempering treatment. The fire-resistant 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...
