摘　　要：在拉挤环氧树脂中添加不同粒径、相同种类的Al(OH)3填料和相同粒径、不同种类的填料,来研究填料粒径和填料种类对拉挤环氧树脂浇铸体的力学性能及玻璃化转变温度的影响。结果显示:在加入相同填充量、不同粒径、相同种类填料的情况下,加入的Al(OH)3填料粒径为5μm时,拉挤环氧树脂浇铸体的拉伸和压缩强度最高;加入相同填充量、相同粒径、不同种类填料的情况下,加入重质碳酸钙的拉挤环氧树脂浇铸体的拉伸和压缩强度最高,其弯曲强度差别不大。加入填料后拉挤环氧树脂的玻璃化转变温度均得到了提高,其中加入粒径为1μm的Al(OH)3填料和煅烧高岭土时的玻璃化转变温度较高。In order to study the effect of filler particle size and filler type on the mechanical properties and glass transition temperature of pultruded epoxy resin castings,different size,same type of Al(OH)3 filler and the same particle size,different kinds of filler are added into the epoxy resin in the present study.The results show that the tensile and compressive strength of the pultruded epoxy resin castings with the Al(OH)3 filler particle size of 5μm is the highest when the same filling amount,different particle size and the same kind of filler are added.When the same filling amount,the same particle size,and different kinds of fillers are added,the tensile and compressive strength of the pultruded epoxy resin casting body which contains the heavy calcium carbonate is the highest,and the bending strength is not much different.The glass transition temperature of the pultrusion epoxy resin is increased after the addition of the filler,and the glass transition temperature is higher when the Al(OH)3 filler with a particle size of 1μm or the calcined kaolin is added.
