A kind of inorganic fireproof and thermal insulation rock mud and using method thereof

Abstract

The invention belongs to the fields of heat insulation, sound insulation and a fireproof material for internal and external parts of wall building construction, and relates to an inorganic fireproof insulation rock mud and an application method thereof. The inorganic fireproof insulation rock mud comprises the following components by weight ratio: a component A fiber gelling powder material comprising 97.55-92.1% of Portland cement, 0.5-1% of fly ash, 1-2% of silicon ash, 2-3% of mineral fiber, 0.05-0.2% of polypropylene fiber, 0.05-0.1% of wood fiber, 0.05-0.1% of fiber meerschaum, 0.1-0.4% of ultrafine inorganic fiber, 0.1-0.3% of hydroxypropyl methyl cellulose, 0.3-0.5% of an alkali resistance agent, 0.2% of re-dispersible latex powder, and 0.1% of a water repellent; and a lightweight aggregate B comprising B1 aggregate expanded perlite with vibration compaction weight being 90-120 kg / <3>, or B2 aggregate closed cell perlite with vibration compaction weight being 95-140 kg / <3>. The application method is characterized by smearing and machinery spray processes. According to the invention, a plurality of materials can be used for preparation in a scientific and reasonable mode, after moulding, the rock mud has a fiber disordered and netted multidimensional stereo tensioning structure, the fireproof grade of the material is high, the heat conduction coefficient is low, the heat insulation performance is good, and the weatherability is strong.

Description

technical field [0001] The invention belongs to the field of thermal insulation, sound insulation, and fireproof materials for wall building structures, in particular to an inorganic fireproof and thermal insulation rock mud composite wall construction material, in particular to an inorganic fireproof and thermal insulation rock mud and its use method . Background technique [0002] In recent years, my country's high-rise buildings have developed rapidly, and the number ranks first in the world. These high-rise buildings are high in height, large in size, and have complex functions and structural insulation systems. The fire safety of the building, stable economy, heat preservation and environmental protection. [0003] At present, my country's construction market is divided into organic and inorganic according to categories; organic such as: EPS polystyrene board, polyurethane, XPS extruded board, phenolic board and other thermal insulation material building construction sy...

AI Technical Summary

Problems solved by technology

[0004] The technical disadvantages of the organic insulation board material building structure system are: at the junction of the organic insulation board material and the wall structure, the cold and hot water does not circulate to produce condensation, resulting in freeze-thaw damage, cracking and falling off of the material structure, especially when some organic insulation board materials are used. Combustible insulation materials, if a fire occurs, toxic and harmful gases will be produced, which will easily cause heavy casualties and property losses

[0005] There are also 5% to 10% inorganic fireproof and thermal insulation mortar construction system materials; such as: a modified expanded perlite thermal insulation mortar and a kind of inorganic vitrified microbead external wall thermal insulation mortar as representatives: poor thermal insulation performance and its thermal conductivity Generally W / (m.K)=0.06, the use of a single ingredient for inorganic fibers is unreasonable and the amount of organic colloidal materials is too large, which makes the material poor weather resistance, easy to pulverize, crack, fall off, and out of sync with the life of the building structure
