Abstract

According to the solvent-free three-in-one compound equipment based on double-sided coating of the middle layer, a middle-layer base material roll is unwound on a first unwinding unit, and a surface-layer base material roll and an inner-layer base material roll are unwound on a second unwinding unit and a third unwinding unit respectively; the middle-layer base material enters the first coating unit to be glued on the front side, the outer-layer base material or the inner-layer base material is compounded for the first time in the first compounding unit to form a double-layer composite film, the double-layer composite film enters the second coating unit, and the second coating unit is used for gluing the back side of the double-layer composite film; and the outer-layer base material or the inner-layer base material and the double-layer composite film are compounded for the second time in the second compounding unit to form the three-layer composite film with the double-side coated middle-layer base material. The three-in-one composite process can be suitable for double-sided gluing of the middle-layer base material.

Description

technical field [0001] The invention relates to a solvent-free composite device, in particular to a solvent-free three-in-one composite device based on double-sided coating of an intermediate layer. Background technique [0002] Solvent-free three-in-one lamination refers to the process of completing solvent-free lamination of three-layer substrates at one time. It has the advantages of high production efficiency, high yield and avoiding the disadvantages of some double-layer lamination processes. Its application is constantly expanding. The usual solvent-free three-in-one composite process is to apply glue twice and apply it on the surface of the two substrates to complete the composite, but in different fields in reality, the surface layer and inner layer of the three-layer composite structure cannot be glued. Or for applications where the glue coating effect is not good, in order to complete this three-layer composite structure, it is necessary to develop a process that c...
