Description

Technical Field

[0001] The invention belongs to the technical field of PET films, and in particular relates to an intelligent production line for surface treatment of PET films. Background Art

[0002] PET film, the full name of which is polyethylene terephthalate film, is a high-performance plastic film. PET film has high durability and firmness, and can resist the impact and wear of the external environment. PET film has excellent toughness and can maintain its integrity under various stress conditions. PET film has excellent heat resistance and cold resistance, and can remain stable at a high temperature of 240°C. At the same time, it still shows good toughness and tenacity in the range of minus 70 degrees Celsius to minus 220 degrees Celsius. PET film has good resistance to a variety of chemicals, such as excellent oil resistance and acid resistance, but poor alkali resistance. PET film has excellent electrical insulation properties and is suitable for insulation protection of various electronic components. PET film is usually a colorless, transparent, and glossy film with good transparency, but poor UV protection. PET film is easy to recycle and meets environmental protection requirements; Surface treatment of PET film is a key step to improve its surface properties and meet specific application requirements. Corona treatment, principle: by applying high-frequency, high-voltage power between the metal electrode and the corona treatment roller, the air is ionized and a large amount of ozone is formed. At the same time, high-energy electric sparks impact the film surface, which increases the surface wet tension of the PET film and is conducive to the attachment of foreign objects. However, corona treatment has time-limited problems, especially in high temperature and high humidity environments, the film tension is easy to decay. It is widely used in pre-printing treatment of PET film to improve printing quality and firmness. Flame treatment, principle: through the flame treatment head on the PET surface The flame treatment method is to cover the PET film surface to make it reach high temperature instantly. Under high temperature, the macromolecules on the PET surface undergo oxidation reaction to produce polar groups, which increases the adhesion of the PET film. However, the flame treatment temperature and the distance between the flame and the PET need to be precisely controlled to avoid under-burning or burning the PET surface. Coating method, principle: a layer of special treatment agent is applied on the surface of the PET film, such as water-soluble polymers, acrylic emulsions, polyurethane aqueous solutions, etc., to increase the surface tension of the PET film, improve printing adaptability, strengthen the bonding force between the aluminum coating layer and the PET base film, etc. It can be used to make high barrier films, antistatic films, etc. Oxygen Chemical treatment, principle: expose the PET film to oxygen or oxidants to cause an oxidation reaction on its surface to form an oxide layer, thereby increasing the surface energy of the PET film and enhancing its wettability and adhesion. Plasma treatment, principle: expose the PET film to plasma to cause a chemical reaction on its surface to form a new surface layer, thereby increasing the surface energy of the PET film and improving its wettability, adhesion and printability. Chemical treatment: immerse the PET film in a specific chemical solution to cause a chemical reaction on its surface to form a new surface layer, thereby increasing the surface energy of the PET film. Silane coupling Agent treatment, principle: Silane coupling agent is coated on the surface of PET film to make its surface chemically react, improve the surface energy of PET film, enhance wettability and adhesion. The surface energy of PET film after surface treatment is significantly improved, which is conducive to the adhesion of ink, adhesive and other materials. Surface treatment methods such as coating and plasma treatment can improve the printing adaptability of PET film, improve printing quality and firmness. Flame treatment, coating and other methods can enhance the adhesion of PET film to other materials. Through specific surface treatment methods, such as coating, special functional films such as high barrier film and antistatic film can be produced; If the surface treatment involves the use of chemical reagents, the drying / curing device is particularly important. This device is used to dry or cure the treated PET film to ensure the durability of the treatment effect; After searching, a drying device for PET protective film production with publication number CN215724945U is found, which includes a drying box, a rack and a telescopic hose.

A plurality of connecting pipes are provided on the upper and lower sides of the protective film, a horizontal pipe is provided at the rear end of the connecting pipe, and connecting blocks are symmetrically provided at the lower end of the horizontal pipe. The technical solution passes the protective film through the through hole on the drying box, starts the exhaust fan 2 to draw the outside air into the air inlet pipe, and then starts the heating pipe to heat the outside air, and the heated air enters the telescopic hose. , cross pipe and connecting pipe, and then blow the protective film through the air outlet, so as to achieve the effect of drying the protective film, and at the same time start the motor to drive the rotating shaft and gear to rotate, and the gear drives the rack, connecting block and connecting pipe to move left and right, so as to facilitate the air outlet to carry out all-round drying treatment on the protective film, and improve the drying efficiency of the protective film. The protective film stays in the drying box for a short time, resulting in a shorter drying time, which affects the drying quality of the protective film and needs to be improved. Therefore, it is particularly important to design an intelligent production line for surface treatment of PET film to solve the above defects. Summary of the invention
