Background ABS material has excellent mechanical properties, but its solvent resistance is poor. Acid solvents are prone to cracking, which will affect the normal use of the product. Technical research is needed to improve this performance defect and solve the technical bottleneck of poor solvent resistance of ABS material, so as to meet the technical demand of energy and other fields and improve the market application field of ABS material. Subject Using ABS and POK resin alloy as matrix resin, a high performance flame retardant ABS alloy material was prepared by developing a high efficiency flame retardant system of brominated antimony. Methods The mechanical properties, crystallization behavior, wear resistance, solvent resistance and heat resistance of the alloy materials were characterized by Fourier infrared spectroscopy, differential scanning calorimeter, universal testing machine, scanning electron microscope and friction tester. Result ABS has a good compatibility with POK, and the alloy material containing 20% POK has excellent mechanical properties and heat resistance, good ice acetic acid resistance and excellent solvent resistance. Through the DSC curve of the alloy material, the relationship between the melting peak area and the content of POK resin was obtained. POK resin can significantly improve the wear resistance of ABS and has a good glossiness retention rate. |
