Embodiment 1
[0053] Take the raw material according to the mass fraction of each component in Example 1 in Table 1; first PEI Ultem 1000 is dissolved in dimethylacetamide (DMAc) organic solvent, and configured into a PEI solution with a solid content of 10wt%, and then the PEEK is finely powder Add 150UF10, glass fiber and ultra-fine fully vulcanized powder acrylate rubber VP-301 into the solution in turn, and stir evenly. Then, the mixed solution was slowly added to deionized water to precipitate, and then boiled and washed with deionized water at 90°C for 3 times, and then dried in an ordinary oven to obtain PEI, PEEK, glass fiber and ultrafine fully vulcanized acrylate rubber. mixed powder. Then mix the powder with PC, BMP-BMI, melamine polyphosphate, tricyclohexylphosphine oxide, octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate, 2 , 2'-oxalamido-bis[ethyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)]propionate, stearic acid, pentaerythritol stearate were added to the high-speed m...
Embodiment 2
[0055] According to the mass fraction of each component in Example 2 in Table 1, the raw materials are weighed; first, PEI Ultem 1010 is dissolved in the DMAc organic solvent, configured into a PEI solution with a solid content of 12wt%, and then the PEEK fine powder Add KT-820UFP, glass fiber and ultra-fine fully vulcanized powder acrylate rubber into the solution in turn, and stir evenly. Then, the mixed solution was slowly added to deionized water to precipitate, and then boiled and washed with deionized water at 85°C for 4 times, and then dried in an ordinary oven to obtain PEI, PEEK, glass fiber and ultrafine fully vulcanized acrylate rubber. mixed powder. Then mix the powder with PC, BMP-BMI, melamine cyanurate, triphenylphosphine oxide, tetrakis[β-(3,5-di-tert-butyl,4-hydroxyphenyl)propionate]pentaerythritol Ester alcohol, tris(2,4-di-tert-butylphenyl) phosphite, N,N'-ethylenebisstearamide, and silicone powder are added to a high-speed mechanical blender and stirred e...
