Description

Technical Field

[0001] The invention belongs to the technical field of foam product processing equipment, and specifically relates to a foam back adhesive laminating and pressing device. Background Art

[0002] Foam is generally made of polymer materials such as polyurethane, polyethylene, and polypropylene, and forms a porous structure through physical or chemical foaming methods. In many applications, such as packaging, heat insulation, and acoustic treatment, it plays an important role. The function of foam adhesive is to improve its adhesion so that the foam can be better connected to other materials. During the preparation process, the foam adhesive and the foam may not be tightly connected. This may be related to the following factors: Surface pretreatment: The surface state of the foam has a significant effect on the adhesion of the adhesive. If there are pollutants or grease on the surface of the foam, the glue may not be able to fully penetrate, resulting in a weak bond. Foaming process control: During the foaming process, if the temperature, pressure and other parameters are not properly controlled, the pore structure inside the foam may change, affecting the bonding effect with the adhesive. Glue curing time and temperature: Factors such as the curing time of the adhesive and the ambient temperature will also affect the bonding strength. If the curing is insufficient or the temperature is too high, the connection will be weak. In order to improve the connection strength between the foam adhesive and the foam, it is necessary to design a foam adhesive laminating and pressing device, through which the foam is pressed again to improve the connection strength between the foam and the foam adhesive.
