Problems solved by technology

In addition to the bubbles that are prone to appear during the production process, the perfusion fireproof glass will quickly turn milky white under the action of ultraviolet rays and flames, and lose the permeability of the glass.
This also determines the complex production process of composite fireproof glass; the weight is heavier, the installation cost is higher; the disadvantages of poor weather resistance

Abstract

The invention provides a single-layer fireproof tempered glass preparation method, and relates to the technical field of building materials. The preparation method comprises the following steps: (1) performing acid treatment on the surface of glass by using a mixed acid solution of nitric acid and hydrofluoric acid, then washing the acid treated glass, and performing drying and preheating; (2) sending the pre-processed glass in the step (1) into a glass tempering furnace to perform glass tempering, wherein the glass tempering temperature is in a range of 650-730 DEG C and the glass tempering time is in a range of 1-2 hours; (3) when the glass is tempered with heating, spraying a cesium-potassium salt solution with a certain composition twice, wherein a second spraying is performed 10-15 min after a first spraying is finished; and (4) taking out the tempered glass and performing air cooling molding, and finally performing cooling to obtain the single-layer fireproof tempered glass. The single-layer fireproof tempered glass provided by the invention is simple in preparation process, convenient in installation, high in impact resistance and high in weatherability.

Description

field of invention [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of single-layer fireproof tempered glass. Background technique [0002] Fire-resistant glass 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-resistant test. The main role in fire prevention is to control the spread of fire or to isolate smoke. It is a measure-type fireproof material. Fireproof glass has the properties of light transmission, fire prevention (smoke, fire, and heat radiation), sound insulation, and impact resistance. It is suitable for architectural decoration of steel and wood fire doors, windows, upper lights, partition walls, lighting roofs, and smoke-blocking vertical walls. , see-through floors and other building components that require both transparency and fire protection. The original glass of fireproof glass c...
