选用３Ｇ（二甲基丙烯酸二缩三乙二醇酯）、ＥＤＭＡ（甲基丙烯酸乙二醇酯）两种稀释剂，并设计４０％、５０％、５５％、６０％、７０％、８０％６种不同重量比例封闭剂配方，测定粘结性能（包括粘度值、渗透性、抗剪粘结强度）、机械性能（包括表面硬度、抗压强度、径向抗张强度）、吸水性和耐磨性。结果表明：３Ｇ作稀释剂优于ＥＤＭＡ，不同稀释剂比例（在４０％～６０％范围内）对封闭剂性能影响不大，总体评价，以４０％～５０％配方比例为最好。
Choose two kinds of thinner such as 3G (ethylene dimethacrylate) and EDMA (ethylene glycol methacrylate), and design 40%, 50%, 55%, 60%, 70%, 80% 6 kinds of different weight ratio of sealing agent formula, the determination of the adhesive properties (including viscosity, permeability, shear bond strength), mechanical properties (including surface hardness, compressive strength, radial tensile strength), water absorption and resistance Grindability. The results showed that: 3G as a diluent is better than EDMA, the different diluent ratio (within the range of 40% to 60%) has little effect on the performance of the blocking agent, the overall evaluation of 40% to 50% formula ratio is the best.
