Problems solved by technology

[0003] Most of the insulation materials in the current construction market are made of organic materials, such as EPS-polystyrene foam, XPS-extruded polystyrene foam, PU polyurethane foam and polystyrene particle insulation slurry. The biggest disadvantage of this type of insulation material is The fire performance is poor, and it is easy to produce a large amount of toxic gas after burning, which is easy to cause casualties

Abstract

The invention relates to a super-light autoclaved inorganic thermal-insulation plate and a preparation method thereof. The super-light autoclaved inorganic thermal-insulation plate comprises, by weight, 250-300 parts of quartz ore powder, 100-120 parts of portland cement, 130-150 parts of lime, 10-15 parts of desulfurized gypsum, 20-25 parts of a thermal-insulation agent, 1-2 parts of a polycarboxylic acid high-efficiency water reducer, 1-2 parts of aluminum paste powder and 500-600 parts of water. The preparation method comprises the following steps of adding all the raw materials but aluminum paste powder into a mixer, carrying out mixing for 4min, adding 1-2 parts by weight of the aluminum paste powder into the mixture, carrying out stirring for 1min, pouring the mixture into a mold, and carrying out precuring, cutting, autoclaving and maintenance to obtain the super-light autoclaved inorganic thermal-insulation plate. Compared with the prior art, the super-light autoclaved inorganic thermal-insulation plate has the advantages of light unit weight, low heat conduction coefficient, sound insulation, noninflammability, no poison gas at a high temperature, acid rain resistance, high strength and construction simpleness.

Description

technical field [0001] The invention belongs to the field of building heat preservation, and in particular relates to an ultra-light autoclaved inorganic heat preservation board and a preparation method thereof. Background technique [0002] The ultra-light autoclaved inorganic insulation board is made of quartz mineral powder, Portland cement, lime and desulfurized gypsum as the main raw materials, and aluminum paste powder as the foaming agent after batching, stirring, pouring, pre-curing, cutting, autoclaving and curing The fine and porous ultra-light sand aerated concrete products made by it have the advantages of light bulk density, low thermal conductivity, sound insulation, non-combustibility, no toxic gas under high temperature, acid rain resistance, high strength, and simple construction; suitable for buildings Fire prevention, heat preservation and heat insulation. [0003] Most of the insulation materials in the current construction market are made of organic mat...
