Problems solved by technology

[0006] There is a phenomenon that it is not convenient to carry out rapid two-way rotation production, which is not conducive to centralized production operations, which will cause certain inconvenience in operation. At the same time, there is also the fact that the inner end is not convenient for the production of the overall output, which is not conducive to the integrated processing output. Improve

Embodiment 1

[0054] A low dielectric loss high-frequency transmission LCP film, prepared from the following raw materials in parts by weight: 90 parts of functional liquid crystal polymers, 14 parts of conductive particles, 17 parts of vinyl ester resin, 56 parts of polyethylene glycol, methyl 32 parts of silicone rubber, 3 parts of dioctyl phthalate, 2 parts of graphene, 1.3 parts of p-phenylenediamine, 0.7 parts of antimony trioxide and 6 parts of γ-aminopropyl triethoxysilane.

[0055] A kind of preparation method of low dielectric loss high-frequency transmission LCP film, such as figure 1 shown, including the following steps:

[0056] a. Prepare functional liquid crystal polymers. The functional liquid crystal polymers are shell-type liquid crystal polymers, the main chain is polyacrylate, and the side groups are phenyl ester mesogens. There is a carbonyl group between the side groups and the flexible side chains. Spacer;

[0057] a. Prepare conductive particles, add the mixed acid ...

Embodiment 2

[0073] On the basis of Example 1, such as Figure 12 As shown, the first workpiece 16 also includes a connecting rod 38 and a contact collar 39, the connecting rod 38 is fixedly connected to the side end position of the material inlet 21, and the side end position of the connecting rod 38 is in phase with the contact collar 39. Fixed connection.

[0074] When this embodiment is in use, the user can help to fix the connecting rod 38 through the setting of the contact collar 39, and the contact collar 39 is used for the side limit work of entering and exiting the membrane body, so as to realize the rapid movement of the membrane body. For production and cooling processing, the connecting rod 38 can help to erect and fix the feeding interface 21, realize mutual connection, and help to perform better processing and production operations.
