Disclosed are silazane compounds having two fluoroalkyl groups, represented by the following general formula (1):
wherein R
f
and R
f
′ are each a fluoroalkyl group, R
1
is a hydrogen atoms or an aliphatic monovalent hydrocarbon group, R
2
and R
3
are each an aliphatic monovalent hydrocarbon group, R
4
is a hydrogen atom or an aliphatic monovalent hydrocarbon group, a and b are each 0 or 1, m, n and p are each an integer of 0 to 6, q is an integer of 1 to 6, and r is 1 or 2. By treating an inorganic material with the silazane compound having two fluoroalkyl groups, high water and oil repellency and high sliding properties can be imparted to the inorganic material in good balance.
本发明涉及具有两个氟烷基团的
硅氮烷化合物,其通式(1)表示如下:
其中,Rf和Rf'均为氟烷基团,R1为氢原子或脂肪族一价碳氢基团,R2和R3均为脂肪族一价碳氢基团,R4为氢原子或脂肪族一价碳氢基团,a和b均为0或1,m、n和p均为0到6的整数,q为1到6的整数,r为1或2。通过使用具有两个氟烷基团的
硅氮烷化合物处理无机材料,可以在良好平衡下赋予无机材料高
水和油抗性以及高滑动性。
