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.

Embodiment

[0010] A thermal insulation board, as shown in the accompanying drawings, from top to bottom is a hollow ceramic bead surface layer 3, a glass fiber mesh layer 4, an expanded perlite composite layer 5, a glass fiber mesh layer 6, and hollow ceramic beads Bottom 7.

[0011] The upper surface of the hollow ceramic bead surface layer 3 is provided with several pits 2, and the outer surface of the hollow ceramic bead bottom layer 7 is provided with several grooves 8. In this embodiment, the purpose of the pits 2 is to When installing, the fixed anchor piece is used. The purpose of the groove 8 is to prevent slippage when bonding the body of wall, and the arrangement is much denser than the pit groove 2. The upper surface of the hollow ceramic bead surface layer 3 and the lower surface of the hollow ceramic bead bottom layer 7 are respectively provided with non-woven fabric layers 1 and 9 made of non-woven fabric. processed.

[0012] In this embodiment, the hollow ceramic bead su...

Abstract

The invention discloses an insulation board. The insulation board sequentially comprises a hollow ceramic bead surface layer, a glass fiber gridding cloth layer, an expanded perlite composite layer, a glass fiber gridding cloth layer and a hollow ceramic bead bottom layer from top to bottom. A plurality of pit slots are formed in the upper surface of the hollow ceramic bead surface layer. A plurality of grooves are formed in the lower surface of the hollow ceramic bead bottom layer from top to bottom. Non-woven fabric layers made from non-woven fabrics are arranged on the upper surface of the hollow ceramic bead surface layer and the lower surface of the hollow ceramic bead bottom layer correspondingly. The insulation board has the advantages of good heat insulation performance, low heat conductivity coefficient, fire resistance, high fireproofing grade, environmental friendliness and the like, and the overall compressive strength is greatly improved.

Description

technical field [0001] The invention relates to a fireproof and thermal insulation material for buildings, in particular to a thermal insulation board. 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 fire resistance performance is not good. The above materials all release a large a...
