Embodiment approach
[0063] As an optional embodiment of the present invention, the preparation method of LCP composite resin comprises the following steps:
[0064] The LCP matrix raw material and the high polymer gel are mixed, and the polymerization reaction is carried out to obtain the LCP composite resin.
[0065] It can be understood that the LCP composite resin uses LCP resin as the main resin, and polymer gel is added in the process of forming (polymerizing) the LCP resin from the LCP matrix raw material. There is no limitation as to whether the high polymer gel is added at the initial stage of formation (initial stage of polymerization reaction) or at the end stage of formation (final stage of polymerization reaction).
[0066] It should be noted that the high polymer gel is added during the polymerization reaction, not after the polymerization reaction is completed. The timing of adding a specific polymer gel is selected to ensure that the polymer gel is uniformly dispersed in the LCP r...
Embodiment 1
[0101] The present embodiment provides a kind of electroplating grade LCP composite material, comprises the raw material of following mass fraction:
[0102] LCP composite resin 79%, reinforcing filler 20% and coupling agent 1%.
[0103] Among them, the LCP composite resin uses the LCP resin formed by the LCP matrix raw material as the main resin, and the high polymer gel is uniformly dispersed in the LCP resin; the repeating units included in the LCP resin include p-hydroxybenzoic acid, 4,4-biphenol, Terephthalic acid and isophthalic acid, the polymer gel is polyphenylene ether resin (the number average molecular weight is 10000, the terminal hydroxyl content is 900), with LCP composite resin as a whole, the combination of LCP resin and polymer gel The mass ratio is 90%:10%; the reinforcing filler is quartz fiber; the coupling agent is titanate coupling agent (Nanjing Shuguang Chemical Group, model: SG-TnBT).
[0104] The preparation method of LCP composite resin comprises t...
Embodiment 2
[0112] This example provides an electroplating-grade LCP composite material, except that the polymer gel in the LCP composite resin is replaced by a polyphenylene ether resin with a number average molecular weight of 10,000 and a terminal hydroxyl content of 900 with a number average For the polyphenylene ether resin with a hydroxyl content of 300, the rest of the raw materials and dosage are the same as in Example 1.
[0113] After testing, the initial flow temperature of the LCP composite resin is 320°C, the dielectric constant is 2.8, and the dielectric loss is 0.0011.
[0114] The preparation method of the electroplating-grade LCP composite material provided in this example is the same as that in Example 1.
