Abstract

The invention relates to a glass formula applicable to production of glass fiber textile yarns. The glass formula comprises components including SiO2, Al2O3, CaO, MgO, K2O, Na2O, TiO2 and Fe2O3; the ratios of the components to a glass design are as follows: (1) the content of the SiO2 is 59.7 to 60.1 percent; (2) the content of the Al2O3 is 12.85 to 19.15 percent; (3) the content of the CaO is 22.4 to 22.8 percent; (4) the content of the MgO is 2.7 to 3.1 percent; (5) the content of the K2O and the NaO is 0.6 to 0.75 percent; (6) the content of the TiO2 is 0.35 to 0.5 percent; (7) the contentof the Fe2O3 is 0.28 to 0.33 percent. By adopting the glass formula provided by the invention, the problems of existing glass fibers that the tensile strength is low and the requirements on performance of the high-performance glass fiber textile yarns cannot be met are solved.

Description

technical field [0001] The invention belongs to the field of glass fiber glass formulations, in particular to a glass formulation of glass fiber textile yarns. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields. [0003] The proportion of each component introduced in glass will directly affect the performance of glass fiber, which is very important to the manufacture of glass fiber, and determines the performance of fiber and the performance of fiber in composite materials. Its main components are silica, alumina, calcium oxide, magnesium oxide, iro...
