Inorganic fireproof thermal insulation plate and preparation method thereof

Abstract

The invention discloses an inorganic fireproof thermal insulation plate and a preparation method thereof. The inorganic fireproof thermal insulation plate is characterized by comprising a hollow ceramic bead surface layer, a fiberglass gridding cloth layer, an expanded perlite composite layer, a fiberglass gridding cloth layer and a hollow ceramic bead bottom layer in sequence from top to bottom. A pit slot is formed in the hollow ceramic bead surface layer; and a groove is formed in the hollow ceramic bead bottom layer. Non-woven fabric layers are respectively arranged on the hollow ceramic bead surface layer and the hollow ceramic bead bottom layer. The hollow ceramic bead surface layer and the hollow ceramic bead bottom layer are made of hollow ceramic bead slurry; and the expanded perlite composite layer is made of expanded perlite composite layer slurry. The preparation method comprises the following steps of preparing the hollow ceramic bead bottom layer, flatly laying the fiberglass gridding cloth layer, preparing the expanded perlite composite layer, flatly laying the fiberglass gridding cloth layer, preparing the hollow ceramic bead surface layer, compacting and molding these layers, and demolding and curing these layers. The invention is advantaged in that the thermal insulation performance of the inorganic fireproof thermal insulation plate is good, the heat conductivity coefficient of the inorganic fireproof thermal insulation plate is low, flame retardant grade and fireproofing grade of the inorganic fireproof thermal insulation plate are high, the inorganic fireproof thermal insulation plate is green and environment-friendly, and the integral compressive strength of the inorganic fireproof thermal insulation plate is greatly enhanced and so on.

Description

technical field [0001] The invention relates to a fireproof heat preservation material for building and a preparation method thereof, in particular to an inorganic fireproof heat preservation board and a preparation method thereof. Background technique [0002] At present, under the impetus of my country's energy conservation and emission reduction policies and energy conservation standards, the building insulation industry has developed rapidly, but insufficient attention has been paid to the fire safety of building materials. Most domestic high-rise buildings use polystyrene foam boards, expanded polystyrene boards (EPS boards), extruded polystyrene boards (XPS boards), polyurethane foam boards, phenolic resin boards, and rock wool boards as external insulation materials. layer. Existing polystyrene boards and polyurethane boards cannot meet the national building fire protection requirements, and phenolic resin boards have certain flame retardant properties, but their fir...

AI Technical Summary

Problems solved by technology

Existing polystyrene boards and polyurethane boards cannot meet the national building fire protection requirements. Phenolic resin boards have certain flame retardant performance, but the fire performance is not good.

The above materials release a large amount of toxic gas in case of fire, and have poor strength and high cost

As an inorganic material, rock wool board is on the verge of being eliminated due to defects such as large water absorption, general thermal insulation performance, difficult construction, and environmental pollution, although its fire resistance performance meets the standards.
