With glue binding metal plate, when use, easily comes off because of high temperature, greatly affected using effect, and manufactured composite board
Intensity it is general, comprehensive function is poor, it is therefore desirable to is improved.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of metal U.S. core plate, it is novel in design, instead of traditional
Multi-layered board, is combined with each other by the mode that glue bonds by the way of hot pressing polymeric membrane, obtained composite board weight
Gently, intensity is big, is provided simultaneously with the multiple functions such as fire prevention, waterproof and sound-absorbing, environmentally protective.
To realize above-mentioned technical purpose, present invention employs following technical solution：
A kind of metal U.S. core plate, it is characterised in that：Including set gradually bottom, the first macromolecule membranous layer, U.S. core layer, second
Macromolecule membranous layer and surface layer, the bottom and surface layer are made of metallic plate, the first macromolecule membranous layer and the second polymeric membrane
Layer uses polymeric membrane that polymeric membrane is compound in the two sides of U.S. core layer, high score respectively by way of hot pressing for material
Sub- film is heated and bonds adjacent layer.
Preferably, U.S.'s core layer is wavy shaped configuration in X-axis and Y direction, it is all provided with the two directions
There is corrugated change structure, further enhancing the overall construction intensity of plate.
Preferably, it is equipped with sound-absorbing ply of paper and acoustical cotton layer, sound-absorbing ply of paper and surface layer on the surface layer successively from the inside to the outside
Between, connected by viscose glue between acoustical cotton layer and sound-absorbing ply of paper.
Preferably, the sound-absorbing ply of paper uses sound absorbing paper, acoustical cotton layer is using the acoustical cotton being installed in cloth bag.
Preferably, the metallic plate uses aluminium sheet, steel plate, copper coin or stainless steel plate.
Preferably, U.S.'s core layer is aluminium core plate, steel core plate, copper core plate or stainless steel core plate.
Preferably, the bottom is punched-plate.
Preferably, the temperature range of the hot pressing is 110 ~ 130 DEG C, make the thawing of polymeric membrane, bond effect more preferable.
By adopting the above-described technical solution, the present invention has the following technical effect that：Metal U.S. core plate substitution of the present invention
The method that traditional glue bonds, by the way of polymeric membrane thermo-compression bonding, its layer of structure is novel in design, firm effect
It is good, it is light-weight, intensity is big, suitable for a variety of building materials fields.
