摘要 以硫脲、乙氧基次甲基丙二酸二乙酯和甲基丙烯酸ω-羟癸酯为主要原料合成了一种新的粘接性单体10-甲基丙烯酰氧癸基-2-硫脲嘧啶-5-羧酸酯。用1H NMR、MS和FT-IR测试技术对产物结构进行了表征,通过剪切强度的测试评价了其对复合树脂与高含金合金、钛合金和钴铬合金之间的粘接所起到的作用。结果表明,10-甲基丙烯酰氧癸基-2-硫脲嘧啶-5-羧酸酯能够促进复合树脂与高含金合金的粘接,当其质量分数为0.5%时,剪切强度达到最大22.4 MPa,但此单体并不能促进钛合金和钴铬合金与复合树脂之间的粘接,剪切强度分别为12.1和13.7 MPa。 10-Methacryloyloxydecyl-2-thiouracil-5-carboxylate was synthesized from the reaction of thiouracil with diethyl ethoxymethylene malonate and ω-hydroxy-decyl-methacrylate. The structure of the product was characterized by ^1H NMR, MS and FT-IR, and the effect of this product on the bond durability between composite resin with Au alloy, Ti alloy or Co-Cr alloy was evaluated. The product significantly elevated the bonding strength between composite resin and Au alloy, and the shear strength was 22.4 MPa when the mass fraction of this product was 0. 5%. But this product could not enhance the bonding strength of the composite resin with Ti alloy and Co-Cr alloy; the shear strength was 12. 1 MPa, 13.7 MPa respectively.
