聚酯和聚酰胺共混改性塑料及其制备方法
摘要：
本发明涉及一种聚酯和聚酰胺共混改性塑料及其制备方法，该聚酯和聚酰胺共混改性塑料是由PTT、PA-6、PE-g-MAH组成；制备包括：(1)干燥PTT、PA-6和PE-g-MAH；(2)干燥好的PTT、PA-6、PE-g-MAH按质量比为20～50∶80～50∶3～4混合均匀；(3)将混合物置于双螺杆挤出设备中，熔融共混，挤出造粒；(4)将所得粒子烘干，烘干即得PTT/PA-6共混改性塑料粒料。该聚酯和聚酰胺共混改性塑料和PA-6塑料相比，吸水性降低，力学稳定性明显改善，因此可应用于工程结构材料等工业领域。
摘要（英）：

The invention relates to a polyester and polyamide blend modified plastic and the preparation method; wherein the polyester and polyamide blend modified plastic comprises the PTT, the PA-6 and the PE-g-MAH; the preparation method is that (1) drying the PTT, the PA-6 and the PE-g-MAH; (2) the dried PTT, the PA-6 and the PE-g-MAH are well-mixed at the rate of 20 to 50: 80 to 50: 3 to 4 in mass; (3)the mixture is put in a double-screw extrusion equipment for extrusion pelletization after melt blending; (4) the particles are dried and the PTT/PA-6 blend modified plastic is got. The polyester andpolyamide blend modified plastic has the advantages of lowed water absorption, improved mechanical stability, thereby is suitable in the engineering structure material industrial fields.
