Development of resin adhesive system by novel ceramic primer

为了了解市售陶瓷底漆的脱气机理，我们设计了由γ-甲基丙烯酰氧基丙基三甲氧基硅烷（γ-MPTS）和4-Meta、MDP或盐酸（HCl）组成的新型陶瓷底漆。通过测量在热循环之前和之后与由新型陶瓷底漆硅烷化的陶瓷的剪切粘结强度来检查树脂的陶瓷粘结耐久性。与4-META或MDP相比，HCl的应用允许更有效地增加陶瓷粘结耐久性，因为HCl提供比4-Meta或MDP更大量的质子化质子以加速γ-MPTS的有机硅官能团中的甲氧基部分的水解。使用HCl可提高树脂的陶瓷粘结耐久性。

In order to understand the degtadation mechanisms of commercially available ceramic primers,we designed novel ceramic primers,consisting of γ-methacryloyloxypropyltrimethoxysilane (γ-MPTS) and 4-META,MDP or hydrochloric acid (HCl). The ceramic bond durability of resin was examined by measuring the shear bond strength to the ceramic silanated by novel ceramic primers,before and after thermo-cycling. Application of HCl allowed for an increase in the ceramic bond durability more effectively than 4-META or MDP did,since HCl provided greater amounts of protonated proton than 4-META or MDP to accelerate a hydrolysis of the methoxy portion in the silicone-functional group of γ-MPTS. Use of HCl increases the ceramic bond durability of resin.
