Abstract
The invention discloses a composite magnesia heat insulation board for an external wall and a manufacturing method of the heat insulation board. The heat insulation board is prepared from the following raw materials in parts by weight: 20-25 parts of magnesia, 3-6 parts of cryolite powder, 1-3 parts of zircon powder, 3-6 parts of egg shell powder, 2.5-3.5 parts of manganese residue particles, 0.5-0.8 part of sodium silicate, 0.8-1.9 parts of magnesium stearate, 6-10 parts of polyphenyl particles, 15-30 parts of water, 0.3-0.8 part of a foaming agent, 0.5-1 part of a water retardant, 5-7 parts of pineapple fiber stuff and 1-7 parts of a compound additive. The composite magnesia heat insulation board for the external wall has a series of excellent characteristics of light weight, porosity, sound insulation, heat resistance, acid resistance, stable chemical property and the like; the fire resistance rating of the heat insulation board reaches requirements of level A; and the heat insulation board has high fire resistance, high weatherability and high durability, and a good sound absorption effect and is free from potential safety hazards.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a magnesite composite exterior wall insulation board and a manufacturing method thereof. Background technique [0002] Building heat insulation is an important aspect of saving energy, improving the living environment and using functions. At present, external thermal insulation technology of external walls is a necessary and key measure for energy saving of building envelope structures. From the perspective of domestic and foreign development, external thermal insulation and fire protection of external walls Safety requirements should be the first choice for the application of this technology. The current insulation board is still difficult to meet high temperature resistance, low temperature resistance, corrosion resistance, wear resistance, sound insulation, heat insulation, flame retardant, waterproof, fire prevention, heat insulation, high strength, impact resistan...
