Problems solved by technology

[0003] Glass fiber is an inorganic non-metallic material with excellent performance. It has good insulation, heat resistance and corrosion resistance, and high mechanical strength. The existing glass fiber composite materials have excellent acid and alkali resistance, rigidity, aging resistance and oxidation resistance All need to be improved. Among many polymer composite materials, fiber reinforced composite materials have excellent comprehensive properties, while glass fibers have good corrosion resistance, heat resistance, good mechanical strength, and low raw material prices. Advantages, it is widely used in composite materials for reinforcement purposes. Since composite materials are made by combining two or more materials through auxiliary methods, there are often phase interfaces between materials due to different properties. Ultimately results in poor performance of the composite due to changes in interlayer shear forces at the interface

Description

technical field [0001] The invention belongs to the technical field of glass fiber materials, and in particular relates to a preparation method of corrosion-resistant glass fiber materials. Background technique [0002] Glass fiber has excellent properties such as good insulation, low thermal conductivity, and strong sound absorption. In recent years, it has been widely used in aerospace, military chemical and other fields. Glass fiber is characterized by excellent physical properties but poor corrosion resistance, which has great limitations in the application of corrosion resistance fields such as construction, chemical corrosion, thermal insulation materials, and high-end packaging materials. Corrosion-resistant glass fiber was invented by a Ph.D. from the British Institute of Architecture, and it was developed and industrialized in the 1970s in cooperation with Pilkington Glass Company of the United Kingdom to produce products. It is mainly used to strengthen cement conc...
