Problems solved by technology

The traditional EPS polystyrene board is processed to obtain ordinary flame-retardant insulation boards of B1 and B2 grades. When exposed to fire, it shrinks, melts, emits black smoke, and the flame is easy to penetrate; graphite polystyrene board: polyphenylene particles added graphite after processing The obtained flame-retardant B1-level insulation board shrinks when exposed to fire, melts, flame-retardant, emits black smoke, and the flame is easy to penetrate; modified polystyrene board is also called thermosetting polystyrene board, which is ordinary polystyrene particles modified by special The flame-retardant B1 grade insulation board obtained after the phenolic resin and other materials coating film is vacuum-dried and cut, does not shrink when exposed to fire, does not melt, is flame-retardant, is not easily penetrated by flames, but emits black smoke , has a pungent smell, and the market mostly pretends to be A2 grade

Abstract

The invention discloses an inorganic foamed building heat insulation board and a making method thereof. The heat insulation board is produced from modified expanded perlite used as a main material through stirring, mixing and molding of a foaming agent and an inorganic slurry. The inorganic foamed building heat insulation board has the characteristics of extremely good temperature stability and chemical stability, no cracking, no shedding, energy saving, environmental protection, no pollution, good fireproof and non-combustible safety, and high strength, can be widely applied to heat insulation materials of various building exterior walls, fireproof isolation strips and roofs, and also has the advantages of simplicity in construction, short construction period, good quality, and great prolongation of the service life of buildings.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and energy-saving building thermal insulation materials, and more specifically relates to an inorganic foamed building thermal insulation board and a preparation method thereof. Background technique [0002] China's external wall insulation industry is a huge market. After repeated entanglements in the building insulation industry about fire safety and energy-saving efficiency, the industry has accumulated a lot of positive and negative experiences and lessons. Although in the past we paid a heavy price for the practice of only focusing on energy saving and ignoring fire prevention, but in recent years, the practice of only focusing on fire prevention and ignoring energy conservation and system security has ignored many safety hazards. No matter other organic insulation materials such as foamed polyphenylene or foamed urethane, they all have defects such as flammability, short dur...
