摘要
UPR/Al2O3 composite particles were synthesized from unsaturated polyester resin(UPR) and nanometer/ultra-fine Al2O3 powders by means of suspension polymerization.The effects of Al2O3 with two different particle diameters on the density and hardness of the composite particles during the synthesis were studied.The results show UPR/Al2O3 composite particles synthesized by suspension polymerization are spherical,smooth,with a yield of 60%～75%(wt),and the particle diameters are 140～250μm;Al2O3 can effectively improves the density and hardness of the composite particles;when the contet is the same,effect of ultra-fine Al2O3 on the density and hardness of the composite particles is better than that of nanometer Al2O3;When the mass fraction of Al2O3 is 55%,the maximum hardness of ultra-fine Al2O3 composite particles and nanometer Al2O3 composite particles are 39.42HV and 25.66HV respectively.
