Embodiment Construction

[0041] In the laboratory, the following formula is used to prepare batch materials, melt into glass blocks, and perform performance testing. In order to further verify the present invention, the glass composition of the inventive composition is experimentally produced in the company's tank kiln production device.

[0042] The performance is as follows:

[0043]

[0044] Through the comparison of the above data, it can be found that SiO 2 An increase in the content can effectively increase the strain point and softening point temperature of the glass, that is, improve the temperature resistance of the glass, and broaden the application of the product in the fields of high temperature, acid and alkali resistance, environmental protection engineering, motor vehicle muffler and other fields. The softening point of the glass fiber in the present invention is above 920°C, which is 70-80°C higher than that of ordinary E glass fiber, the strain point is 80°C higher, and the tempera...

Abstract

The invention relates to a chemical corrosion-resistance, high-strength and high-modulus glass fiber composition. The above glass fiber has high strength, high modulus, high temperature resistance, corrosion resistance and other comprehensive performances. The composition can be widely applied in high-performance composite materials and in heat and corrosion resistant environment. The composition is characterized in that 0.5-1.5wt% of ZrO2 is added, and no Li2O, TiO2 or F2 is added, so the high strength and the high modulus of the composition are guaranteed, and the acid and alkali resistance of glass is improved. The glass fiber composition adopts a SiO2-Al2O3-CaO-MgO four-component system as a main component, and mainly comprises 59.0-62.0wt% of SiO2, 16.0-19.0wt% of Al2O3, 8.0-13.0wt% of CaO, 9.0-11.0wt% of MgO, 0.5-1.2wt% of R2O and 0.5-1.50wt% of ZrO2. The glass fiber composition can realizes tank furnace process direct production.

Description

technical field [0001] The invention relates to a chemical corrosion-resistant high-strength and high-modulus glass fiber composition, in particular to the field of high-performance composite materials where E glass fiber cannot meet the requirements, and can be used in wind power blades, gas cylinders, chemical pipelines, heat-resistant and corrosion-resistant environmental protection It is widely used in the field of engineering and power engineering. Background technique [0002] With the increasing expansion of glass fiber in the fields of transportation, industry, construction, and environment, in special fields such as higher strength, modulus, acid and alkali resistance, and aging resistance, ordinary alkali-free glass fibers have been eliminated due to their performance defects. Can not meet market demand. At present, there are many kinds of high strength and high modulus glass fibers on the market. For example, S-2 and R glass fiber, the tensile strength of the fi...
