Problems solved by technology

The price of polystyrene board is low, and its thermal insulation performance is relatively good, but the material is flammable. For example, the fire in the CCTV building in Beijing, the fire in the teacher's apartment in Jing'an District, Shanghai, and the fire in Shenyang Dynasty Hotel caused huge loss of personnel and property.
Foamed polyurethane board has excellent flame retardant and thermal insulation performance, but it is expensive and unacceptable in the market
The other type is inorganic materials mainly rock wool. Although rock wool is grade A non-combustib

Abstract

The invention discloses a composite rockwool panel with flexible surface layers and a preparation method of the composite rockwool panel, belonging to the technical field of building insulation materials. The composite rockwool panel with the flexible surface layers has a stratified structure, which comprises one flexible surface layer, a bonding layer, a middle insulating layer, a bonding layer and the other flexible surface layer from bottom to top; the middle insulating layer and the flexible surface layers are connected by the bonding layers; the middle insulating layer is made from rock wool, the bonding layers are made from foam polyurethane, and the flexible surface layers are made from a cement coating glassfiber mat or cement coating cloth. The invention also provides the preparation method of the composite rockwool panel with the flexible surface layers. Compared with a composite rockwool panel in the prior art, the composite rockwool panel provided by the invention has the advantages that the heat conductivity coefficient is low, the binding is firm, and the dampproof and crack-proof properties are realized; furthermore, the simple preparation process of the composite rockwool panel allows assembly line large-scale production.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a flexible surface layer composite rock wool board and a preparation method thereof. Background technique [0002] Insulation materials are indispensable materials in the construction field. Since 2004, the country has attached great importance to building energy conservation. From the original recommended use to the current mandatory use and the release of energy-saving regulations, higher requirements have been put forward for energy-saving products. After more than 10 years of market selection, there are mainly two types of insulation materials on the market, one is organic materials, mainly polystyrene boards (foam boards), and foamed polyurethane boards. The price of polystyrene board is low, and its thermal insulation performance is relatively good, but the material is flammable. For example, the fire in the CCTV building in Beijing, the fire i...
