Description
Technical Field
The invention relates to the field of film deep processing, in particular to a production line device and a production process for LCP film heat treatment deep processing.
Background
With the advent of the 5G era, various 5G communication devices have higher frequencies and higher transmission speeds, and thus have made higher demands on dielectric constants, dielectric dissipation factors, and the like of electronic materials used for the devices. The traditional epoxy-based copper clad laminate and polyimide-based copper clad laminate cannot meet the electrical performance requirements necessary for high-frequency communication, and the Liquid Crystal Polymer (LCP) high Polymer material becomes the most important basic material for producing the copper clad laminate in the 5G era due to low moisture absorption, good chemical resistance, high gas barrier property and extremely low dielectric constant and dielectric loss factor.
The LCP molecules have the forming characteristic of strong self-orientation along the melt rheological direction, so that the LCP molecules are easily oriented along the stress direction under low shear stress to form a fibrous structure, the orderliness of chain accumulation is formed, the heat resistance and excellent mechanical property of the LCP material are ensured by the rigid rod-shaped molecule homodromous fiber texture, and the obvious self-reinforcing effect is realized in a solid state. On the other hand, however, the texture of the microfibers is extremely disadvantageous for plastic processing into films. If a certain included angle is formed between the stress direction of the fiber orientation plastic processing, the film is easy to crack, and the continuous production of the film cannot be realized, and the LCP film with continuous and regular appearance can be produced only by specially developing and designing a reverse double-rotation die head and a matched processing technology. Analysis shows that the key points of the film blowing process are as follows: firstly, after a high-temperature molten extruded material enters a rotary die head, the orientation regularity of the LCP melt surface layer fibrous body needs to be broken as much as possible through the reverse rotation of an inner die head and an outer die head; and secondly, adjusting the thickness and the production speed of the film by controlling the process parameters such as the rotating speed, the blow-out angle of the melt, the viscosity and the flow of the extruded melt and the like. Through the analysis of the technological characteristics of the film blowing process, the blown bottle-shaped film has certain film thickness fluctuation deviation and a thickness direction layered structure (the difference between the film surface layer and the film middle layer is obvious) after being cut, and the gradient change of the temperature in the film blowing process is superposed, so that the key performance indexes of the produced film, such as the Coefficient of Thermal Expansion (CTE) and the dielectric constant (D) of the film, required by the subsequent processing and application are causedk) And plastic processing and forming and the like have larger fluctuation and serious anisotropy and cannot meet the use requirement, so that the blown film can meet the performance requirement under a high-frequency high-speed service environment only by performing thickness structure reforming and matched heat treatment optimization.
The existing LCP film on-line heat treatment technology is monopolized by a few foreign enterprises, adopts a sectional treatment mode, and has high price and long delivery time.
