Problems solved by technology

But the disadvantage is that the glass transition temperature Tg (143 ° C) is relatively low, and the price is expensive, and the cost of use is high, which limits its application.
[0003] At present, in the prior art, the following improvements or researches have been proposed to address the above-mentioned shortcomings of the single material. "Study on properties and mechanical properties" shows that the polyether ether ketone / polyphenylene sulfide blend system has good processing fluidity in the molten state, but it is in a state of phase separation in the solid state, and the mechanical properties decline seriously. Affected its application after molding
Another example is the Chinese invention patent CN201610343123.4 which discloses a PPSU (polyphenylene sulfone) and PEEK alloy material. 5 to 15 parts; the binary alloy material combines the characteristics of PEEK and PPSU materials, but with the increase of PPSU content, the tensile elastic modulus of the alloy material decreases seriously, and the rigidity and other properties are insufficient, which seriously limits the application of the alloy material
