Abstract

The invention discloses a high-strength glass fiber with low thermal expansion coefficient, which belongs to the technical field of glass fiber. The glass fibers of the present invention consist of the following components: SiO 2 59.0~69.0%, Al 2 o 3 13.5~25.0%, MgO 6.0~10.0%, B 2 o 3 1.0~6.0%, CeO 2 0.5~2.0%, ZnO 0.1~4.5%, TiO 2 0.1~4.0%, ZrO 2 0.1~3.0%,H f o 2 0.1~2.0%, Li 2 O 0.1~2.0%; of which TiO 2 , ZrO 2 、H f o 2 The sum of the contents is 1.0-5.0%. The low expansion coefficient high strength glass fiber of the present invention does not add CaO, K 2 O, Na 2 O component, add B 2 o 3 , ZnO, TiO 2 , ZrO 2 、H f o 2 , while increasing the content of silicon and aluminum, reducing the content of boron and magnesium, and adding an appropriate amount of CeO 2 , under the premise of ensuring that the difficulty of production is appropriate, glass fibers with low expansion coefficient and high strength can be obtained.

Description

technical field [0001] The invention relates to the technical field of glass fibers, in particular to a glass fiber with low thermal expansion coefficient and high strength. Background technique [0002] Glass fiber is an excellent inorganic non-metallic material with good insulation, strong heat resistance, good corrosion resistance, and a wide variety. With the development of economy, glass fiber has become an indispensable material in construction, transportation, electronics, electrical, chemical, metallurgy, aviation, national defense and other industries. [0003] However, with the development of science and technology, the performance requirements of glass fiber in printed circuit boards, national defense, aviation, etc. are getting higher and higher. The strength, elastic modulus, and thermal expansion coefficient of existing glass fibers can no longer meet the performance requirements, and the strength, elastic modulus, and thermal expansion coefficient of glass fi...
