1、有机硅的定义凡是含Si-C键的化合物通称为有机硅化合物,习惯上也常把那些通过氧、硫、氮等使有机基与硅原子相连接的化合物也当作有机硅化合物。其中,以硅氧键(—Si—O-Si—)为骨架组成的聚硅氧烷,是有机硅化合物中为数最多,研究最深、应用最广的一类,约占总用量的90%以上。由于有机硅兼备了无机材料与有机材料的性能,因而具有耐高低温、电气绝缘、耐臭氧、耐辐射、难燃、憎水、耐服饰、无毒无味以及生理惰性等优异特性,广泛运用于电子电气、建筑、
1, the definition of silicone Si-C bond containing compounds commonly known as the organosilicon compounds, customary also often those through oxygen, sulfur, nitrogen and other organic compounds and silicon atoms connected to the organic compounds are also used as. Among them, the silicones (-Si-O-Si-) as the backbone of the polysiloxane composition, is the largest number of organic silicon compounds, the most studied, the most widely used category, accounting for more than 90% of the total amount . Silicone has excellent properties such as high and low temperature resistance, electrical insulation, ozone resistance, radiation resistance, flame retardancy, water repellency, resistance to clothing, non-toxic and tasteless as well as physiological inertia due to the combination of inorganic materials and organic materials.
