Study on Influencing Factors of Properties of Heat-resistant ABS Resin
The acrylonitrile butadiene styrene(ABS)resin was modified,and the effects of different contents of heat-re-sistant agent(MS-NB),different types of compatibilizers(HPC-20,KT-22),and different processing conditions on the properties of heat-resistant ABS resin were investigated.The results show that with the increase of heat-resistant agent con-tent,the heat resistance and bending strength of ABS resin increase,while the tensile yield strength and flow property decrease,and the bending modulus is not affected.Compatibilizer HPC-20 can improve the mechanical properties and fluidity of heat-resistant ABS resin,while KT-22 has the opposite effect.The processing conditions have no effect on the heat resistance of the material.When the main engine speed is high,the bending property of the material is excellent.However,when the bending property and flow property are better at low speed at medium shear strength.The impact strength increases with the increase of shear strength.The mechanical properties and heat resistance of the material decreased with the increase of the temperature of extrusion section.
