【摘要】：采用硅膠對制備的HAP晶須進行表面改性形成SiO_2顆粒附著,然后以硅膠改性的HAP晶須為填料混合甲基丙烯酸酯制備復(fù)合樹脂材料。二氧化硅對晶須改性是通過形成凝膠顆粒與晶須結(jié)合并通過熱處理形成牢固的結(jié)合。通過XRD、FT-IR光譜和SEM以表征微結(jié)構(gòu)、鍵性質(zhì)以及表面相組成。結(jié)果表明:經(jīng)硅膠改性的HAP晶須表面有SiO_2小顆粒附著,隨著煅燒溫度的增加,SiO_2顆粒的數(shù)量明顯增多,尺寸有變大的趨勢。復(fù)合樹脂材料的彎曲強度隨改性晶須煅燒溫度的增加而增加,以600℃煅燒的改性晶須為原料制備的樹脂樣品,其彎曲強度最高,達到89.46 MPa。
[Abstract]:HAP whiskers were modified by silica gel to form SiO_2 particles, and then HAP whiskers modified by silica gel were used as fillers to prepare composite resin materials. Silica modifies the whisker by forming the gel particles and the whisker and heat treatment to form a strong bond. The microstructure, bond properties and surface phase composition were characterized by XRD- FT-IR and SEM. The results show that there are small SiO_2 particles on the surface of HAP whiskers modified by silica gel, and the number of SiO2 particles increases obviously with the increase of calcination temperature, and the size tends to become larger. The flexural strength of the composite resin increases with the increase of the calcination temperature of the modified whisker. The flexural strength of the resin sample prepared by calcining the modified whisker at 600 鈩，
