Basalt fiber reinforced foam base composite heat-preservation layer and producing method thereof

Abstract

The invention relates to a production method for a basalt fiber reinforced foam base composite heat-preservation layer. The production method is characterized by comprising the following steps: 1, producing a compressed plate; 2, arranging a heat-preservation layer on the compressed plate; 3, performing detection and aftertreatment. By adopting the production method provided by the invention, compressed plates made of basalt fiber fabrics / needled felt in a compressing manner are added on two sides of a foam plate, so that the properties of heat insulation, noise reduction and flame retardancy improvement, of the heat-preservation layer can be improved, the loss caused by fire hazard can be reduced, a comfortable and quiet rest environment can be provided for people in daily life, and meanwhile, the strength of the heat-preservation layer is improved to a certain extent when being compared with that of a pure foam plate heat-preservation layer.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a basalt fiber reinforced foam-based composite thermal insulation layer and a manufacturing method thereof. Background technique [0002] At present, most of the insulation layers used for the exterior walls of houses are foam boards. This kind of foam insulation layer can usually keep the indoor temperature in a comfortable range for the human body, but the use of foam insulation layers will reduce the fire resistance of the building. At present, the relatively mature external insulation layers for houses on the market are EPS (expanded polystyrene board) and polystyrene foam insulation boards, but EPS has the disadvantages of poor strength and easy cracking. The polystyrene foam insulation board will go through a period of maturity when it leaves the factory, and it needs to be placed for a period of time before it can be used. At the same time, its own strength is limited and...

Problems solved by technology

[0004] Patent CN 102817415A proposes a novel method for manufacturing basalt fiber wall insulation boards, but since the structure as a whole is made of basalt fibers, the overall quality is relatively heavy, which is not conducive to transportation and application, and the cost is too high. suitable for mass production

Although the foam-based insulation layer is relatively light in weight, its flame resistance is relatively poor. Therefore, the present invention proposes a basalt fiber reinforced foam-based insulation layer for external use in houses. Compared with the patent CN 102817415A, the quality and cost will be greatly reduced. The flame resistance of the foam insulation layer of the structure will be significantly improved
