The invention relates to a novel silane coupling agent according to Formula (1) below, wherein Y = a chain composed of aliphatic, cyclic or aromatic groups, furthermore comprising an additional reactive group chosen from the series of a secondary amine, a amine linked to a secondary or tertiary carbon atom or a hydroxyl group linked to a primary, secondary or tertiary carbon atom. R, R'= CH3 or C2H5, n = 3-15, q = 1, 2 or 3 and p = 3-q. The invention also relates to the use of the coupling agent according to the invention in a composite, for example in a dental application. The invention further relates to a process for the preparation of a silane coupling agent by reacting, at a temperature lower than 150° C, a carbonyl bislactamate with a silane compound containing at least one amino group. The invention moreover relates to nano particles, in particular nano silicate particles, obtained by hydrolysis of the coupling agent according to the above formula in the presence or absence of tetraethoxysilane and to the use of such particles in a coating.
本发明涉及一种新型硅烷偶联剂,其化学式如下(1),其中Y=由脂肪族、环状或芳香族基组成的链,还包括来自于次级胺、连接到次级或三级碳原子的胺或连接到一级、二级或三级碳原子的羟基等系列中的额外反应基团。R,R'= CH3或C2H5,n= 3-15,q= 1、2或3,p= 3-q。本发明还涉及将该偶联剂用于复合材料中,例如在牙科应用中。本发明还涉及通过在低于150°C的温度下反应含有至少一个氨基的硅烷化合物和羰基双乳酰胺制备硅烷偶联剂的方法。本发明还涉及通过在存在或不存在四乙氧基硅烷的情况下水解上述化学式的偶联剂获得的纳米颗粒,特别是纳米硅酸盐颗粒,并将其用于涂层中。
