Problems solved by technology
However, this kind of board needs to go through the electroplating process in production, which will cause inevitable environmental pollution and consume precious metals. At the same time, it will also consume a lot of energy. The subsequent processing of organic coatings will consume a lot of heat and release a lot of volatilization. Organic solvents that pollute the environment
What is even more unfavorable is that during the use of the packaging body used for packaging food, the coating on the inner layer that is in contact with food may precipitate certain chemical components and contaminate the food. At the same time, the acidity or other components of the contained items will also affect Corrosion of interior coatings shortening their shelf life

Embodiment Construction
[0023] like figure 1 As shown, the environment-friendly polyester composite steel plate of the present invention includes a steel plate body 3, and polyester films 1 and 2 are bonded on the upper and lower surfaces of the steel plate body 3, respectively. The steel plate body 3 can be cold-rolled thin plate, tin-free steel plate (TFS), 08AL, Q195, Q195L, SPCC, SPCD, SPCE, etc. The thickness of the steel plate body 3 is 0.1mm-0.5mm, preferably 0.2mm-0.5mm. Polyester film 1, 2 is PET polyester film, and thickness is 5um~100um, and its preferred thickness is 10um~50um, when the thickness of polyester film is less than 5um, then easily produce pinhole, and it is difficult to ensure the durability of polyester composite steel plate. Corrosion, when its thickness is greater than 100um, because it is too thick, the film will peel off or crack in the deep processing of the product, and the cost will also increase. Polyester film can be mixed with various resin additives in polyester ...

Abstract
The invention discloses an environment-friendly polyester clad steel plate and a manufacturing method thereof. The steel plate comprise a steel plate body which is subject to degreasing cleaning and surface passivation treatment to form a layer of passivation film, polyester film is adhered to the upper surface and the lower surface of the steel plate body respectively. The environment-friendly polyester clad steel plate has the functions of acid resistance, alkali resistance, water resistance, solvent resistance and the like, can be processed by bending, stretching, beading and the like, and the aims of rust resistance, decoration and protection can be achieved by one-time processing. The production process avoids environmental pollution and a great deal of energy consumption caused by a plating process. The steel plate has high production efficiency and low cost.
Description
technical field [0001] The invention relates to an environment-friendly polyester composite steel plate and a manufacturing method thereof. Background technique [0002] At present, the vast majority of canning and packaging plates in my country are cold-rolled thin plates made of tin-plated or chrome-plated plates (TFS plates, tin-free plates) by electroplating, and then coated with one or more layers of organic coatings on both sides or one side. For protection and decoration, and then made into various cans, barrels, boxes and other packaging bodies. With the improvement of people's living standards year by year in our country, the demand for this packaging material is also increasing. However, this kind of board needs to go through the electroplating process in production, which will cause inevitable environmental pollution and consume precious metals. At the same time, it will also consume a lot of energy. The subsequent processing of organic coatings will consume a lot...
