The release paper mainly comprises a substrate layer, an isolation layer and a release layer. Wherein, the substrate layer has the functions of supporting and printing, and is generally selected from 60g/m2In the above paper, the bulk and heat resistance of the base paper need to be controlled; the isolating layer has the function of preventing the release agent from penetrating into the paper and isolating the paper substrate layer from the release agent layer, and the processing method mainly comprises a film spraying method (also called plastic coating) at present and generally adopts Polyethylene (PE); the release layer mainly plays a role in preventing adhesion, and a silicon-based release agent is generally adopted. The traditional production process of the release paper generally comprises the following steps: printing is firstly carried out on the substrate layer, then an isolation layer is formed on the substrate layer in a laminating mode, and then silicon coating is carried out to form a release layer. However, in the production process, especially in the production process of the double-sided laminating release paper, in the process of silicon coating (i.e. coating the release agent), due to the characteristics of solvent volatilization and self-curing of the release agent, higher energy, i.e. higher temperature, is required in the process, however, higher temperature in the process of silicon coating can cause evaporation of moisture in the substrate layer (especially the paper substrate), and further cause the phenomena of bubbles, delamination and the like on the surface of the laminating layer, which affects the stable proceeding of the silicon coating process and even causes product rejection.
In order to solve the above problems, in the conventional processing technology, the substrate layer is generally dried before the lamination. However, in the actual production process, the energy consumption of the added drying procedure is very large and can reach 60 kW/hour, so that the production cost is greatly increased, the energy consumption is overlarge, and the aims of environment-friendly production and high efficiency and energy conservation are difficult to achieve.
