Description

A composite insulation board

technical field

These two mortar layers have their own advantages in addition to making the insulation board have a fireproof function and enhancing the structural strength of the insulation board.

Background technique

Existing composite insulation boards are usually composed of high-density boards and polystyrene foam layers compounded between high-density boards. Although this polystyrene foam composite board has the advantages of light weight and good sound insulation effect, its fireproof effect is poor. The polystyrene foam inside the composite board is very easy to burn in case of fire, fueling the fire and posing safety hazards. In order to solve the problem of fire prevention, a new type of inorganic composite insulation board has appeared on the market. The insulation board is made of perlite or vitrified microbead material, and has a good fireproof effect. It is easy to break during handling and use. In addition, due to its low strength, it is impossible to produce large-sized insulation boards, which brings great inconvenience to production and use.

How to design a thermal insulation board, which not only has the function of fire prevention, but also has higher strength, so as to be easy to process and use, is a key problem to be solved urgently by those skilled in the art.

Utility model content

The purpose of the utility model is to provide a composite thermal insulation board, which not only has the function of fire prevention, but also has higher strength, so that it is easy to process and use. In order to achieve the above object, the utility model provides the following technical solutions:

A composite insulation board, comprising:

Insulation layer, the insulation layer is an inorganic material insulation layer;

A mesh cloth layer, the mesh cloth layer is adhered to at least one surface of the heat preservation layer;

Inorganic material insulation layer has better fireproof function. The mesh cloth layer can improve the toughness and strength of the entire composite insulation board, and at the same time facilitates the application of the mortar layer. The smearing of the mortar layer can not only improve the strength of the entire composite thermal insulation board, but also enhance the fireproof function of the composite thermal insulation board. Therefore, the composite thermal insulation board has high strength while having good fireproof function, so that it is easy to process and use.
