Abstract

The invention provides a magnesium oxysulfate light-body fireproof heat-insulation plate. The magnesium oxysulfate light-body fireproof heat-insulation plate is prepared through the modes that a polystyrene foaming heat-insulation material serves as a base material and the surface of the polystyrene foaming heat-insulation material is covered with an inorganic membrane, and the mass ratio of the polystyrene foaming material to the inorganic membrane is 1:(12-25); and the inorganic membrane contains magnesium hydroxide powder and magnesium sulfate, and the mass ratio of the magnesium hydroxidepowder to the magnesium sulfate is 1:(0.1-0.8). The magnesium oxysulfate light-body fireproof heat-insulation plate meets the A2 standard of 'GB50016-2014 code of design on building fire protection and prevention', and the strength of plates can be obviously improved. The magnesium oxysulfate light-body fireproof heat-insulation plate is low in cost, the comprehensive technology effect of the plate manufactured by combining the vacuum adsorption technology and other technologies is good, and the magnesium oxysulfate light-body fireproof heat-insulation plate has the expected huge economic value and social value.

Description

technical field [0001] The invention relates to the technical field of preparation and application of a fireproof heat preservation board, and in particular provides a magnesium oxysulfide lightweight fireproof heat preservation board. Background technique [0002] In the prior art, due to frequent fire accidents related to building thermal insulation materials in recent years, all walks of life have paid great attention to thermal insulation and fire prevention. Many fires of insulation materials are generated during the construction process, such as: electric welding, open flames, bad construction habits, etc. During the burning process of these materials, the molten droplets and toxic smoke are continuously produced, and the harm to the environment of the released gases such as chlorofluorocarbons, hydrofluorocarbons, and freons cannot be ignored. For this reason, the Ministry of Housing and Urban-Rural Development and the Ministry of Public Security jointly issued the "...
