Fireproof A1 level inorganic interior and exterior wall heat insulation board and production method thereof

Abstract

The invention discloses a fireproof A1 level inorganic interior and exterior wall heat insulation board and a production method thereof. The heat insulation board comprises 60-80wt% of Portland cement, 0-21wt% of slag powder, 10-35wt% of fly ash, 1.4-2wt% of a waterproof agent, 1-2wt% of iron oxide black, 0.1-0.34wt% of fiber, 0.01-0.8wt% of cellulose, 0.3-1.2wt% of an early strength agent, and 7-12wt% of a foaming agent. The invention also provides a production method of the fireproof A1 level inorganic interior and exterior wall heat insulation board. The heat insulation board is produced by adopting inorganic materials, so the heat insulation board has the advantages of certain compressive strength and tensile strength, light weight, water and fire proofing, corrosion proofing, sound insulation, heat insulation, non-toxicity, no peculiar smell, small heat conduction coefficient, freeze and thaw resistance, and good weather ability, has same life with a unit building, and is a most rational exterior heat insulation material. Repeated construction, repeated investment and repeated pollution are avoided in the invention. The heat insulation board and the production method have good economic, social and environmentally friendly benefits.

Description

technical field [0001] The invention relates to the field of thermal insulation board insulation wall, in particular to a fireproof A 1 A grade inorganic interior and exterior wall insulation board and a preparation method thereof. Background technique [0002] Before 2011, organic thermal insulation materials accounted for 97% of the entire thermal insulation material market, which is also the main reason for the high incidence of fires, and organic materials themselves are a product of energy conversion (energy-based materials), so there are many problems. Waste of energy, easy to age, continuous pollution to the environment, easy to fall off, poor weather resistance, short life, poor fire resistance, difficult construction, repeated 2-4 times of construction within the life of a unit building, inevitably leading to repeated pollution, Repeated construction, repeated investment. At present, both at home and abroad are stepping up the development of alternative products, ...

AI Technical Summary

Problems solved by technology

[0003] The existing thermal insulation materials are basically organic, and the main materials are based on organic materials, that is, energy materials, and have a short service life, are flammable, toxic, polluting, and have poor freeze-thaw resistance. The service life is only 15-20 years. high price
