Abstract

The invention belongs to the technical field of glass fibers, and specifically relates to a low-bubble low-dielectric glass fiber composition and a production process thereof. The composition comprises the following components: 55.0-58.0% of SiO2, 19.0-21.0% of B2O3, 13.5-15.0% of Al2O3, 2.5-4.5% of MgO, 3.0-5.0% of CaO, 3.0-3.3% of ZrO2, less than or equal to 0.5% of K2O+Na2O and less than or equal to 0.5% of Fe2O3. The invention further provides the production process of the composition. The production process provided by the invention solves problems of poor melting property and poor homogenization and clarification effect of low-dielectric glass fibers by strictly regulating the grain size grade of each raw material and controlling the grain size dispersity of each raw material, and solves problems of high viscosity and easy phase separation of the low dielectric glass fibers by adjusting the proportion of each component through optimizing the formula.

Description

technical field [0001] The invention belongs to the technical field of glass fibers, and in particular relates to a low-bubble and low-dielectric glass fiber composition and a production process thereof. Background technique [0002] Due to a series of excellent properties such as high temperature resistance, corrosion resistance, high strength, low specific gravity, low moisture absorption, small elongation and good insulation, glass fiber has been widely used in electronics, communications, nuclear energy, aviation, aerospace, weapons, ships and marine development. , genetic engineering and other high-tech industries, but due to the high dielectric constant of E glass, printed circuit boards using glass fibers drawn from E glass as reinforcing materials cannot meet the requirements of today's high-density and high-speed information processing. [0003] In order to increase the signal transmission speed of printed circuit boards and meet the high-speed calculation needs of ...
