Embodiment 1-9

[0062] A preparation method for extruding and calendering polyphenylene sulfide (PPS) copper-clad laminate material, comprising the following steps:

[0063] (1) After preparing the materials according to the components and ratios described in Examples 1-9, except for the glass fiber, mix at high speed for 5 minutes through a high-speed mixer;

[0064] (2) The above-mentioned mixed material is granulated through a twin-screw extruder, glass fibers are added downstream of the twin-screw extruder, the twin-screw speed is 550 rpm, and the temperature is 295°C;

[0065] (3) Finally, the above-mentioned granules are melted and plasticized by a twin-screw extruder, extruded from a die (1.0mm thick), shaped by a calender, and coated with copper online to form a PPS copper-clad laminate of a certain thickness.

Abstract

The invention relates to an extruded and rolled polyphenylene sulfide copper-clad plate material and a preparation method thereof. The PPS material is specifically prepared from 40 to 70 parts of PPS resin, 5 to 15 parts of PAR resin, 10 to 30 parts of PPO resin, 5 to 20 parts of LCP resin, 0 to 40 parts of glass fiber, 2 to 5 parts of compatilizer, 0 to 20 parts of inorganic filler, 0.2 to 1.5 parts of lubricant and 0.2 to 1.5 parts of antioxidant. Compared with the prior art, the extruded and calendered polyphenylene sulfide copper-clad plate material disclosed by the invention can be used for continuously producing a copper-clad PPS material by using an extrusion calender through a one-step method, has excellent binding power with a copper foil, and has the advantage of lower cost; meanwhile, the ceramic has the excellent characteristics of high heat resistance, low dielectric constant and dielectric loss, low water absorption rate, low thermal expansion coefficient and the like meeting high-frequency use, and can be applied to an SMT (Surface Mount Technology) process. The method is especially suitable for various devices such as 5G base station antenna arrays and filter carrier plates.

Description

technical field [0001] The invention relates to the technical field of preparation of copper-clad laminate materials, in particular to an extruded and calendered polyphenylene sulfide copper-clad laminate material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) material has extremely high mechanical strength and low water absorption, and it has low dielectric constant and dielectric loss, which ensures the reliability of the material under the use of high-frequency signals, and can also meet the requirements of SMT process. Compared with metal devices, it has a one-time molding process, reduces the installation process, has higher processing accuracy, and is lighter in weight, which is more conducive to saving costs. Therefore, PPS has a very cost-effective advantage in 5G base stations as antenna oscillators and filter carrier boards. However, the current PPS sheet mainly has two usages, one is to use electroplating or LDS laser...
