Embodiment Construction
[0022] Below in conjunction with specific embodiment, further illustrate the present invention.
[0023] Such as figure 1 The PVC film gluing system shown includes:
[0024] The PET unwinding roll 1 also includes a heating roll 2, an upstream pressing roll 3 and a downstream pressing roll 4 used in conjunction with the heating roll 2; the PET film 11 is unwound by the PET unwinding roll 1 and wound around the heating roll 2, and passes through the upstream An embossing roller set 13 is also provided at the end of the pressing roller 3 , the downstream pressing roller 4 , and the heating roller 2 .
[0025] The upstream PVC unwinding roller 5 is used in conjunction with the upstream PVC unwinding roller 5 and is used in conjunction with the upper chute 6 for containing the PVC paste resin 10, and the first upper feeding roller 7 is arranged on the upper chute 6; the PVC film 12 is unwound from the upstream PVC After unwinding at the roller 5, go through the feeding roller 7 t...

The invention relates to a production process of a PET (Polyethylene Tterephthalate) advertisement material. In the conventional process procedure, a PET film is long in production procedure and needs multiple guide wheels, so that the rate of finished products is low, and the rate of finished products is generally about 70%. The production process is characterized by comprising the following steps: adopting a PVC (Polyvinyl Chloride) sizing system for sizing; firstly, coating PVC paste resin on an upstream PVC film roller and subsequently pressurizing and compounding a single side hot roller of the PET film; secondly, coating the PVC paste resin on a downstream PVC film roller and subsequently pressurizing and compounding a hot roller of the PET film on the other side, wherein the temperature for pressurizing and compounding the hot roller is 180-190 DEG C; and calendaring, cooling and coiling up the finished products after the PET film is compounded with the PVC film. By utilizing the PVC paste resin provided by the invention, the tight combination of the PVC with the PET is ensured, and a process procedure that the PET film is sized with PU (Poly Urethane) adhesive and is further baked in an oven is omitted, so that the machining process procedure for producing the PET advertisement material is effectively shortened, and machining steps for the PET film are reduced. In the process for producing the PET, the PET only passes through about ten guide wheels, and the structure is greatly simplified due to the new PEV sizing system, so that the production efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to a production process of PET advertising materials. Background technique [0002] PET material has the characteristics of high hardness, poor elasticity, and no ductility. It is not suitable for long-distance transportation during the production process (prone to wrinkling and discounting). Such as figure 1 As shown, at present, when producing PET advertising materials, the PET film is first exported, preheated and ironed by the preheating roller, and then coated with PU glue on the front and back of the PET film, and then guided by multiple guide wheels into the oven for drying. Finally, it is laminated with PVC film. In this process, the PET film has to pass through a total of more than 30 guide wheels up and down. The production process is long, there are many guide wheels, and because of the PET material, it is difficult to control the wrinkling and discounting of PET during the production process, resulting in a low prod...
