Foam composite panels are phenolic resin and flame retardants and curing agents and other auxiliaries in the scientific formula made of closed cell rigid foam, its outstanding advantages are fire and heat preservation. As a new type of thermal insulation material, compared with the traditional thermal insulation material, it has the characteristics of fire resistance, low smoke and high temperature resistance. Even when it is burning, it only burns on the surface and then forms a protective layer on the opposite foam.
It has the characteristics of corrosion resistance and aging resistance, almost all inorganic acids and organic solvents. Moreover, there are many other characteristics, such as small bulk density and light weight. Precisely because of this, it can reduce the self weight of the building, reduce the load of the building, reduce the structural cost, and the construction is simple and fast, which can improve the work efficiency. Moreover, this kind of thermal insulation material has another excellent performance, that is, it can absorb sound, It can cut off the noise to a great extent.
Foam composite board is a kind of metal plate covered on a layer of foam board to achieve the effect of saving resources and reducing costs without reducing the use effect (corrosion resistance, mechanical strength, etc.). Composite methods usually include composite method, rolling composite, rolling composite, etc. Composite materials can be divided into composite plate, composite pipe, composite rod, etc. It is mainly used in anti-corrosion, pressure vessel manufacturing, power construction, petrochemical, pharmaceutical, light industry, automobile and other industries.
A nonwoven polystyrene foam composite board for thermal insulation of engineering is composed of composite nonwovens on the upper and lower surfaces of polystyrene foam plastic plates. It can be used directly in the process of extruding foamed polystyrene foam board to heat the nonwovens directly. The electricity can be applied to the surface of the cooling molded polystyrene foam board, and the adhesive is formed by bonding the nonwoven fabric.
The utility model uses the non-woven fabric on the surface of the polystyrene foam plastic plate as the adhesive medium for the insulating layer and the base and the decorative surface layer. During the construction, through the good permeability of the nonwoven fabric to the adhesive, the solid combination of the polystyrene foam plastic plate with the matrix and the decorative surface layer can be realized. Compared with the current insulation board, not only the bonding strength is significantly improved, but also the bonding construction can be carried out with ordinary cement glue, and the treatment processes such as adding glass fiber mesh and surface grinding are omitted, so as to improve the construction efficiency and greatly reduce the project cost
