Description
Technical Field
The invention relates to the technical field of building materials, in particular to a gypsum-based vitrified micro-bead insulation board for the internal insulation of an external wall and a processing method thereof.
Background
The building energy-saving wall system comprises an outer wall outer heat-insulating wall system, an outer wall inner heat-insulating wall system and a sandwich composite heat-insulating wall system; the three systems are different in the position of the heat-insulating layer in the wall body; if the heat-insulating layer is arranged on the outer side of the main body wall structure, the heat-insulating layer is called external wall external heat-insulating; if the heat insulation structure is arranged on the indoor side of the main wall, the heat insulation structure is called as outer wall inner heat insulation; if the heat insulation plate is arranged between two layers of dense structure walls on the same outer wall, the sandwich composite heat insulation is called. At present, the heat insulating materials can be divided into two types from the composition: thermal insulation mortar and thermal insulation boards; the material can be divided into organic and inorganic heat-insulating materials. The thermal conductivity coefficient of the thermal insulation mortar is relatively low, but the thermal insulation mortar must be stirred on a construction site; the construction period is long. The heat-insulating board can be prefabricated, cut and assembled on site; the construction efficiency is high.
The external wall external insulation has potential safety hazards of easy falling and flammability; in recent years, fire accidents and falling-off injury accidents of external wall external insulation are frequent, so that the internal insulation construction process of the external wall is emphasized and popularized and applied in various places. The traditional construction process of the polyphenyl particle thermal insulation mortar for the inner wall is complicated, the construction period is long, the leveling is difficult in the construction process, and the strength is poor. The polyphenyl particle thermal insulation mortar is an organic thermal insulation mortar material prepared by taking polyphenyl particles as a lightweight aggregate and polyphenyl particle thermal insulation rubber powder materials according to a certain proportion. The material can be applied to construction by adding water and stirring into slurry on a construction site, and can be used for internal and external heat preservation of building external walls. The polystyrene particles are all called expanded polystyrene foam particles; due to the material of the material, the material belongs to a flammable thermal insulation material, and the flame retardant grade can only reach B2 grade; the flame-retardant and fire-retardant properties are relatively poor. The vitrified microsphere insulation board is a board compressed by vitrified microsphere raw materials, and has the characteristics of very stable physical and chemical properties, strong aging resistance and weather resistance, excellent heat insulation, fire prevention and sound absorption because the surface is vitrified to form certain particle strength.
The vitrified micro bubble insulation board in the prior art still has a complex processing mode; the processing technology period is long; the strength is insufficient; poor fire-proof performance.
