Description

一种高性能玻璃纤维
技术领域:
本发明涉及玻璃纤维丝技术领域,具体涉及一种高性能玻璃纤维。
背景技术:
在国内外的玻璃纤维丝生产过程中,玻璃配方主要有无碱和中碱两种,C玻璃即中碱玻璃,是用于生产连续玻璃纤维常用的玻璃成分。中碱玻璃成分的基础是SiO2-CaO-Na2O三元系统,其组分及重量百分比含量为:SiO2 68~82%;CaO 6~16%,Na2O:12~18%,生产的产品普遍通用,但是产品的性能主要是强度不高,一般都在0.3N/tex~0.4N/tex之间。
发明内容:
本发明的目的是提供一种高性能玻璃纤维,它引入了钛和锂,导致玻璃纤维的结构发生变化,以SiO2-Al2O3-CaO三元系统为基础,有利于改善玻璃的机械强度、耐高温性及化学稳定性,同时具有相对较低的成型温度和液相线温度,减少了玻璃失透的危险,有利于玻璃纤维的良好拉制,同时该玻璃纤维还保持了较高的机械强度。
为了解决背景技术所存在的问题,本发明是采用以下技术方案:它的组成成分及组分含量重量百分比如下:SiO2:54.8~56.2%、Al2O3:10.5~12.5%、CaO:19.8~21.3%、MgO:3.2~4.5%、RO=CaO+MgO:23~25%、TiO2:2.9~4.1%、K2O:0.5~2.0%、ZnO:1~3%、Fe2O3:0.1~0.5%、Li2O:1~2%。
本发明的操作步骤如下:
一、各组成物从适当的原料中获取(如石英纱中的SiO2,石灰石中的CaO),按适当比例将各种原料进行混合,使各成分达到最终的预期重量百分比;
二、将混合后的配合料在池窑中熔化并澄清,形成的玻璃液通过通路流至位于通路底部的纤维成型漏板,玻璃液通过漏板上的漏嘴被拉出从而形成玻璃纤维,玻璃纤维被牵引绕到拉丝机旋转机头上形成原丝饼或纱团,这些玻璃纤维可用常规方法进行深加工以符合预期要求。
本发明具有以下有益效果:它引入了钛和锂,导致玻璃纤维的结构发生变化,以SiO2-Al2O3-CaO三元系统为基础,有利于改善玻璃的机械强度、耐高温性及化学稳定性,同时具有相对较低的成型温度和液相线温度,减少了玻璃失透的危险,有利于玻璃纤维的良好拉制,同时该玻璃纤维还保持了较高的机械强度。
具体实施方式:
本具体实施方式采用以下技术方案:它的组成成分如下:SiO2:55%、Al2O3:11.5%、CaO:20%、MgO:3.5%、RO=CaO+MgO:23.5%、TiO2:3.5%、K2O:1.5%、ZnO:2%、Fe2O3:0.3%、Li2O:1.5%。
所述的(CaO+MgO)与MgO的比例范围为:5<(CaO+MgO)/MgO<15。
本具体实施方式的操作步骤如下:
一、各组成物从适当的原料中获取(如石英纱中的SiO2,石灰石中的CaO),按适当比例将各种原料进行混合,使各成分达到最终的预期重量百分比;
二、将混合后的配合料在池窑中熔化并澄清,形成的玻璃液通过通路流至位于通路底部的纤维成型漏板,玻璃液通过漏板上的漏嘴被拉出从而形成玻璃纤维,玻璃纤维被牵引绕到拉丝机旋转机头上形成原丝饼或纱团,这些玻璃纤维可用常规方法进行深加工以符合预期要求。
本具体实施方式具有以下有益效果:它引入了钛和锂,导致玻璃纤维的结构发生变化,以SiO2-Al2O3-CaO三元系统为基础,有利于改善玻璃的机械强度、耐高温性及化学稳定性,同时具有相对较低的成型温度和液相线温度,减少了玻璃失透的危险,有利于玻璃纤维的良好拉制,同时该玻璃纤维还保持了较高的机械强度。
