Abstract
Nanoparticles of SiO2 have a large specific surface area and are often used as inorganic fillers to enhance the properties of resins.The study investigates the effects of nanoparticle SiO2 as a reinforcement phase on the properties of acrylonitrile-butadiene-styrene(ABS)ternary copolymer photosensitive resin.A comprehensive investigation of the morphology and elemental distribution of ABS/SiO2 resin was carried out using various characterization methods,including energy-dispersive spectroscopy(EDS),scanning electron microscopy(SEM),viscosity testing,and tensile testing.The thermal stability of the samples was tested using a thermogravimetric analyzer.The results show that after surface modification of ABS resin with nanoparticle SiO2,the mechanical properties of the material are significantly improved.When the mass fraction of nanoparticle SiO2 is 1.0％,the mechanical properties of the specimen are optimal,with tensile strength and elongation at break increasing by 12.7％and 20.0％respectively compared to the matrix,while the Shore hardness remains at 86.Moreover,the addition of nanoparticle SiO2 can enhance the thermal resistance of ABS resin.When the mass fraction of nanoparticle SiO2 is 1.0％,the 50％weight loss temperature,maximum weight loss rate temperature,and residual carbon content of ABS resin increased by 5.0℃,4.5℃,and 1.18％,respectively.SEM analysis results indicate that the surface of the ABS resin matrix sample is smooth,while the roughness of the sample containing SiO2 increases,the crack propagation path is deflected,and the toughness is enhanced.关键词
