Reflective thermal insulation energy-saving brick

Abstract

The invention relates to a reflective heat-insulating energy-saving brick, which comprises a hollow brick body or a hollow block body provided with a plurality of through holes, each of which is a rectangular hole, and the rectangular holes of the hollow brick body or hollow block body are at least A layer of reflective heat insulating material is provided on the inner wall facing the outer wall or on the rib wall separating the through holes. The reflective heat preservation and heat insulation energy-saving brick of the present invention applies heat preservation and heat insulation principles to the interior of hollow bricks or hollow blocks. The reflective heat preservation and heat insulation energy-saving brick has no exposed flammable materials, which not only improves heat preservation and heat insulation Performance, but also improve the fire effect.

Description

technical field [0001] The invention relates to a material for an energy-saving wall, in particular to a reflective heat-insulating energy-saving brick. Background technique [0002] At present, building thermal insulation is mainly to increase the thermal resistance by adding thermal insulation materials to the outer wall of the building, so as to achieve the purpose of thermal insulation. However, most of the insulation materials installed on the exterior walls of buildings are flammable materials, and polystyrene boards (including EPS and XPS) are used more, accounting for about 80%; polyurethane boards (PU) account for 10%, and other new types Material is about 10%. Among them, EPS, XPS, and PU materials account for the largest market share. Even if a large amount of flame retardants are added to EPS, XPS, and PU materials, although they can reach B2 level, the cost will increase greatly. On September 25, 2009, the Ministry of Public Security and the Ministry of Housin...

AI Technical Summary

Problems solved by technology

Therefore, adding a large amount of flame retardants to EPS, XPS, and PU materials will bring about a substantial increase in costs on the one hand, and on the other hand, there are still difficulties in quality supervision of materials from the perspective of construction practice.

Flammable EPS, XPS, PU and other materials are widely used in the market as insulation materials for building exterior walls, which poses serious safety hazards. Once a fire occurs, EPS, XPS, PU and other materials will release a large amount of poisonous gas when burning, and the consequences will be very serious. serious
