Inorganic fireproof heat insulation board and preparation method thereof

Abstract

The invention discloses an inorganic fireproof heat insulation board and a preparation method thereof. The inorganic fireproof heat insulation board is characterized by including a hollow ceramic bead surface layer, a glass fiber grid cloth layer, an expanded perlite composite layer, a glass fiber grid cloth layer and a hollow ceramic bead bottom layer from top to bottom; potholes are arranged on the hollow ceramic bead layer, and grooves are arranged on the hollow ceramic bead bottom layer; non-woven cloth layers are arranged respectively on the hollow ceramic bead surface layer as well as the bottom layer; further, 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 includes the following steps: preparing the hollow ceramic bead bottom layer; spreading the glass fiber grid cloth; preparing the expanded perlite composite layer; spreading the glass fiber grid cloth; preparing the hollow ceramic bead surface layer; compacting for formation; and demoulding and solidifying. The inorganic fireproof heat insulation board has the advantages of excellent heat insulation performance, low thermal conductivity, fire resistance and high fireproofing grade, environmental protection and the like; further, the integral compression strength is greatly improved.

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.

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.
