Technical Field

However, with the rapid development of electronic and electrical and automobile industries in recent years, the demand for engineering plastics with high strength and high toughness is increasing, and the commonly used polyamide engineering plastics cannot meet the performance requirements of many parts of automobiles and electrical appliances due to the defects of large water absorption, poor dimensional stability, and low impact strength at low temperature and dry state. And the polyamide is blended and modified by acrylonitrile-butadiene-styrene (ABS for short), so that the defects of the polyamide can be improved to a certain extent, and the application field of the polyamide is enlarged. The PA/ABS alloy obtained by blending has the oil resistance and heat resistance of PA and the toughness and rigidity of ABS, so that the impact strength and the fluidity are improved.

When the pyrene red coloring PA/ABS is used, the maleic anhydride grafting auxiliary agent and the pyrene dye are subjected to chemical reaction in the blending process, the mechanical property of the PA/ABS alloy is severely reduced, and the composite material cannot meet the severe weather environment and has poor mechanical property.

According to the analysis of the test data, the test data of the example 13 is optimal comprehensively, compared with the test data of the example 12, when the stabilizer and the light stabilizer are added into the components simultaneously, the dosage of the ultraviolet absorbent is reduced, and the stabilizer has the precipitation risk, so the test data of the examples 1-11 are not added with the ultraviolet absorbent; in example 13, a light stabilizer is added alone, the amount of the ultraviolet absorber added is increased, better performance can be achieved, the DE value is less than 3, the color change rate is low, better weather resistance is achieved, and the light aging performance is strong. Meanwhile, the embodiment 13 has better mechanical properties, which are reflected in notch impact, tensile yield strength, elongation at break, bending strength and bending modulus, and has better wear resistance while improving compatibility through the synergistic effect of PA6, ABS, glass fiber, a second compatilizer and a second wear-resistant agent, and the prepared alloy material has improved mechanical properties; the surface hardness of the alloy material is increased, and the surface friction coefficient is reduced.
