Description
Technical Field
The invention belongs to the technical field of high polymer materials, and relates to a high-strength high-toughness ABS material.
Background
Polypropylene (PP) is a general plastic with wide application, light weight, low cost, easy processing, higher heat distortion temperature, capability of being used at a high temperature of 120 ℃, and has the defects of insufficient strength and rigidity, poor low-temperature toughness and larger molding shrinkage rate. ABS (acrylonitrile-butadiene-styrene) has excellent mechanical properties compared with PP, can be used in the range of-40-100 ℃, has better dimensional stability, and is widely applied to safety guards such as helmets, shields and the like. However, the cost is high, and the processing fluidity and heat resistance are inferior to those of PP. The two are blended to complement the performance and widen the application range. However, the compatibility of the nonpolar PP and the polar ABS is poor, and a certain amount of compatilizer is needed to be added to improve the compatibility of the nonpolar PP and the polar ABS, so that the plastic alloy with better performance can be obtained.
Glass fiber is a common stiffening filler, but when the glass fiber is directly applied to an alloy, the phenomenon of floating fiber easily occurs, the appearance is affected, and meanwhile, the floating fiber is not beneficial to post-processing such as paint spraying, water transfer printing and the like. Talc is another common stiffening filler that imparts high rigidity to the material, and small additions do not affect the appearance of the part, but can significantly reduce the toughness of the material.

Table 1 test results
As can be seen from Table 1, examples 1 to 3 had tensile strengths of about 36.5MPa and elongation at break exceeding 300%. Comparative example 1 the use of PP instead of modified PP increases the cohesion and energy dissipation capacity of the material, effectively preventing crack propagation, and thus comparative example 1 has poor elongation at break. Comparative example 2 uses nano talc powder instead of modified nano talc powder, and its tensile strength is poor. The compatilizer in comparative examples 3-4 is one of maleic anhydride grafted PP and butadiene-styrene block copolymer, which results in reduced compatibility of raw material components, poor interfacial bonding strength and poor tensile property.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
