[0019] Example 1
[0020] The invention proposes a production process of a double-sided film-coated color steel plate for construction, which comprises the following steps:
[0021] S1: Select the substrate roll material, and the weight of the substrate roll material is greater than 300kg, and carry out preliminary cleaning of the substrate roll material, and then synchronously and evenly roll-coat the weather-resistant and environmentally friendly transparent glue on the front and back sides of the substrate roll material. During the roll coating process, The production line speed is 30 m / min, and it enters the oven after roller coating;
[0022] S2: Then, the front and back surfaces of the substrate coil are heated in an oven, and the heating temperature is 204°C. After passing through the oven, an adhesive layer can be formed on the front and back surfaces of the substrate coil, and the adhesive The thickness of the layer is 4 μm;
[0023] S3: The substrate coil processed...

[0028] Example 2
[0029] The invention proposes a production process of a double-sided film-coated color steel plate for construction, which comprises the following steps:
[0030] S1: Select the substrate roll material, and the weight of the substrate roll material is greater than 300kg, and carry out preliminary cleaning of the substrate roll material, and then synchronously and evenly roll-coat the weather-resistant and environmentally friendly transparent glue on the front and back sides of the substrate roll material. During the roll coating process, The production line speed is 33 m / min, and it enters the oven after roller coating;
[0031] S2: Then, the front and back surfaces of the substrate roll are heated in an oven, and the heating temperature is 210° C. After passing through the oven, an adhesive layer can be formed on the front and back surfaces of the substrate roll, and the adhesive The thickness of the layer is 5 μm;
