Description

Technical Field

[0001] This utility model relates to the field of fluoroplastic film preparation technology, and in particular to a coating device for preparing a fluoroplastic film for foamed silicone. Background Technology

[0002] Foamed silicone is a new type of polymer material made through a special foaming process. It has a soft and comfortable feel, as well as good elasticity and resilience, allowing it to quickly return to its original shape after being compressed. Its lightweight texture and significantly lower density than ordinary silicone give it a clear advantage in applications where weight is a concern. Furthermore, foamed silicone possesses excellent resistance to high and low temperatures, resisting deformation, hardening, and embrittlement. It also exhibits good chemical stability, resisting most chemicals and being less susceptible to corrosion and aging. Foamed silicone has wide applications in numerous fields. In the medical field, due to its non-toxic, odorless, and biocompatible properties, it is often used to make medical mattresses and pillows, providing comfortable support for patients. In the electronics field, it can serve as a cushioning pad and sealant for electronic devices, effectively reducing shock, noise, and dust, protecting electronic components from external environmental influences. In the automotive industry, silicone foam is used to manufacture car seats, headrests, and interior seals to improve ride comfort and vehicle sealing. It can also be found in everyday products, such as high-end yoga mats and sports protective gear, where its softness and elasticity provide users with a good experience and protection.

[0003] Fluoroplastic films for foamed silicone use polytetrafluoroethylene (PTFE) as the main raw material. Its unique molecular structure endows the fluoroplastic film with excellent chemical stability, low surface energy, and resistance to high and low temperatures. During preparation, PTFE resin undergoes molding and extrusion pre-forming treatment, followed by a biaxial stretching process to arrange the molecular chains in both longitudinal and transverse directions, forming a film material with a unique microporous structure. This microporous structure effectively prevents the foamed silicone from sticking together during vulcanization, while ensuring smooth heat and gas transfer, guaranteeing the uniformity and stability of silicone foaming. However, without coating during preparation, the film is more prone to aging and oxidation, thus affecting its performance. With technological advancements, coating equipment mainly consists of a feeding system and a coating... The coating system consists of a coating mechanism, a transmission system, and a control system. The feeding system includes a tank for storing the fluoroplastic material solution and a precision metering pump, which can accurately control the amount of material supplied to ensure uniform coating. The coating mechanism typically employs a doctor blade type, a roller coating type, or a spray coating type. The doctor blade type coating device precisely controls the coating thickness by adjusting the gap between the doctor blade and the fluoroplastic film substrate. The roller coating type uses the rotation of the roller to evenly coat the material onto the substrate surface. The spray coating type can atomize the material to allow it to adhere quickly and evenly. The transmission system is responsible for driving the fluoroplastic film substrate to move smoothly and ensure the continuity of the coating process. However, this type of coating mechanism cannot coat evenly, resulting in insufficient coating in some areas, which in turn leads to aging during use and affects the performance.
