Inorganic heat-insulation fireproof plate

Abstract

Disclosed is an inorganic heat-insulation fireproof plate, namely a silica bead fireproof heat-insulation plate. The fireproof plate is made of vitrified small balls and xonotlite, the weight ratio of the vitrified small balls to the xonotlite ranges from 1:2 to 1:5, in addition, waterproof materials with the weight ranging from 1% to 5% of the total weight of the fireproof plate and gel materials with the weight ranging from 8% to 10% of the total weight of the fireproof plate are added, and the fireproof plate is manufactured via working procedures including preparation, screening, pressure forming and drying. The vitrified small balls replace traditional common expanded perlite and traditional common polyphenyl particles to be used as lightweight aggregates of dry mixed heat-insulation mortar, shortcomings that the expanded perlite is high in water absorption and easy in pulverization and is high in volumetric shrinkage during slurry stirring, accordingly, low long-term strength, hollowing and cracking of a product are caused easily, and the like are overcome, defects of flammability, poor fireproof performance, harmful gas generation at a high temperature, low ageing resistance and weather fastness, high rebounding during construction and the like of the polyphenyl particles are also overcome, and comprehensive performances and construction property of the heat-insulation mortar are improved. In addition, the hydrophobic vitrified small balls cannot be degraded at a high temperature and are not easy to deform, and the flame retardant property of a polymer can be improved when the vitrified small balls are used as filling materials of the polymer.

Description

technical field [0001] The invention relates to a building plate, in particular to a new type of plate with the function of heat preservation and fire prevention. Background technique [0002] As my country's modernization develops faster and faster, there are more and more high-rise buildings in cities, and the fire prevention problems of high-rise buildings are becoming more and more serious. The tragedy caused by the high-rise fire in Shanghai in 2011 is even more serious. Alarm bells were ringing. In order to reduce the casualties caused by fire as much as possible, the outer walls of high-rise buildings are usually made of fireproof boards, but most of the materials used in the current fireproof boards are polystyrene particles or expanded perlite as the skeleton raw material, because of its light weight and The effect of fire prevention, but polyphenylene particles are organic materials, once burned, it will cause the release of toxic gases, which may cause greater cas...

Problems solved by technology

In order to reduce casualties caused by fire as much as possible, the exterior walls of high-rise buildings are usually made of fireproof boards, but most of the materials used in the current fireproof boards are polystyrene particles or expanded perlite as the skeleton raw material, because of its light weight and The effect of fire prevention, but polyphenylene particles are organic materials, once burned, it will cause the release of toxic gases, which may cause greater casualties, while expanded perlite has high water absorption and is easy to pulverize, and its volume shrinkage rate is large during slurry mixing , It is easy to cause low strength and hollowing cracking in the later stage of the product

Therefore, there are certain defects in the current fireproof boards.
