Problems solved by technology

Special monolithic fireproof glass refers to the glass whose glass substrate is a special composition, mainly including borosilicate fireproof glass, aluminosilicate fireproof glass, and microcrystalline fireproof glass. It has a high softening temperature and a small thermal expansion coefficient. Generally, it will not burst or deform due to high temperature under flames. It is a high-quality fire-resistant glass, but the production cost is high and the market price is expensive. At present, composite laminated fire-resistant glass and ordinary single-piece fire-resistant glass are still the main products in the market.
[0005]Single-piece fire-resistant glass is generally processed by super-strong physical tempering technology, with high surface stress, poor stability, no heat insulation, easy self-explosion, and low yield in random inspection High, there are safety hazards when used in building exterior windows
The composite fire-resistant glass produced by the grouting method has good heat insulation, but poor weather resistance, and it is easy to turn white after exposure to light, and the permeability is affected. It cannot be used in batches for outdoor energy-saving fire-resistant windows.
At present, most domestic fireproof liquids for composite fireproof glass are generally made by direct mixing of water and water glass, and there are defects such as easy occurrence of air bubbles, poor weather resistance, insufficient hardness, and low visible light transmittance, which affect the performance of external windows in buildings. use on

Abstract

The invention relates to the technical field of manufacturing of glass products, and particularly relates to a piece of non-heat insulation type composite fireproof glass and a manufacturing method of the non-heat insulation type composite fireproof glass. The non-heat insulation type composite fireproof glass comprises a fire facing glass layer and a fire backing glass layer, wherein a support spacing body is arranged between the fire facing glass layer and the fire backing glass layer, a fireproof sealant is filled at the periphery of the support spacing body; a closed cavity enclosed by the fire facing glass layer, the fire backing glass layer and the support spacing body is filled with an inorganic transparent fireproof adhesive layer. The non-heat insulation type composite fireproof glass has the characteristics of good appearance quality, good weather fastness, good heat resistance, high visible light transmittance and high strength, when a fire disaster occurs, the inorganic transparent fireproof adhesive layer absorbs a large quantity of heat and is foamed and expanded to become a non-transparent white fireproof adhesive plate after the fire facing glass layer is broken, the heat produced in the combustion is effectively prevented from conducting and spreading to the side back to fire from the fire facing side, the fireproof integrity is further kept, the roles in protecting life and wealth of people are played, and the non-heat insulation type composite fireproof glass is suitable for fireproof glass for an external window of a building.

Description

technical field [0001] The invention relates to the technical field of glass product manufacturing, in particular to a non-heat-insulating composite fireproof glass and a manufacturing method thereof. Background technique [0002] With the progress of the society and the rapid development of the construction industry, high-rise buildings have sprung up one after another. The higher the building is, the higher the requirements for building glass materials are. Various safety glass and special glass have gradually entered people's field of vision. If a fire breaks out in a high-rise building, it will be fatal. The "May 25 Henan Nursing Home Fire Accident" in 2015, the "11.15 Fire Accident" in Jing'an District, Shanghai in 2010, and the "2.3 Dynasty Wanxin Hotel Fire" in Shenyang in 2011 are all blood. The lessons of fire and fire are vivid and shocking. Relevant ministries and commissions of the state pay special attention to the requirements of building fire protection. [0...
