Embodiment 1
[0011] The total content of each component in this example is slightly less than 100%. It is understood that the residual amount is trace impurities or components that cannot be analyzed; the specific preparation process is as follows: each raw material is proportioned according to the components in Table 1, and after mixing evenly, put platinum Crucible, melting and heat preservation at 1550-1600°C for 3 hours, pour the prepared glass into water to make broken glass, put it into the crucible furnace after drying, and flow out through the porous platinum leak plate for wetting agent coating Draw again with a wire drawing machine to obtain the original silk cake or yarn ball of the glass fiber composition, and then use conventional methods to carry out deep processing to meet the expected requirements; use a high-temperature glass viscometer to measure the forming viscosity (log3 temperature); in a platinum-alloy ship, by exposing the glass to an isothermal gradient for 8 hours,...

Abstract
The invention belongs to the technical field of glass fiber and relates to an enhancement type spinning high-strength and high-modulus glass fiber composition applied to the fields of electromechanics, chemical engineering, aircrafts and the like. The enhancement type spinning glass fiber composition is prepared from, by weight, 56-65% of SiO2, 15-21% of Al2O3, 9-18% of MgO, 5-13% of CaO, 0.1-4% of Y2O3, 0-0.8% of Li2O, 0.1-1% of K2O+Na2O, and 3% or less of other impurities. The enhancement type glass fiber composition is prepared through a tank furnace technological process, by means of optimization and combination of the oxide components and particularly the introduction of Y2O3, the melting temperature, the clarification temperature and the shaping temperature of the enhancement type glass fiber composition are reduced under the situation that high strength and high modulus are guaranteed, the temperature difference between the shaping temperature and the liquidus temperature is increased, the wiredrawing situation is improved, and the enhancement type glass fiber composition is beneficial to the industrial production of high-strength and high-modulus fibers.
Description
Technical field: [0001] The invention belongs to the technical field of glass fiber preparation and relates to a reinforced textile high-strength and high-modulus glass fiber composition, which can be used in the fields of electromechanical, chemical and aircraft as a new type of material. Background technique: [0002] Glass fiber is an inorganic non-metallic material with excellent performance. It is usually used in various fields of the national economy such as reinforcing materials in composite materials, electrical insulation materials, heat insulation materials, and circuit substrates. High-strength and high-modulus glass fibers were originally used in the field of national defense and military industry. With the development of science and technology, high-strength and high-modulus glass fibers are now widely used in wind blades, high-pressure vessels, offshore oil pipelines, automobiles and aviation. Typical high-strength and high-modulus glasses mainly include S-glas...
