Abstract

The invention relates to a preparation method for glass fiber. The method comprises the following steps: 1) mixing and fusing raw materials, and wiredrawing to form a crude fiber product; 2) putting the crude fiber product into a muffle furnace, removing water attached to the glass fiber surface, and then performing acid-base immersion cleaning, thereby acquiring a refined glass fiber product; 3) soaking the refined glass fiber product into a NaOH solution and then taking out, washing with distilled water, taking out and dispersing in absolute ethyl alcohol of a coupling agent KH570, regulating pH and dispersing with an ultrasonic meter, thereby acquiring a semi-finished product of glass fiber; 4) removing surface alkali liquor by spraying the surface of the semi-finished product of glass fiber with warm water, then soaking in clean water, and washing with the assistance of a hot water pump till the pH value is less than 6, thereby acquiring a to-be-finished product of glass fiber; 5) performing thermal shaping treatment on the to-be-finished product of glass fiber, and performing gumming, grouting and drying on the surface, thereby acquiring the end product. The preparation method has the advantages of simple structure, low cost and suitability for large-scale industrial manufacturing.

Description

technical field [0001] The invention belongs to the technical field of glass fiber production, and in particular relates to a glass fiber preparation method. Background technique [0002] With the continuous development of the economy, the demand for glass fiber in industrial smelting, welding and other industries has increased sharply. At present, some alkali-free glass fibers are used, which have a very short life and poor heat insulation. Damaged, thereby endangering personal safety, its acid and alkali resistance, rigidity, anti-aging, high temperature resistance properties need to be improved. [0003] Among many polymer composite materials, fiber-reinforced composite materials have attracted widespread attention because of their excellent comprehensive properties, such as high impact resistance, high modulus, high mechanical properties, and high wear resistance. Glass fiber has the advantages of good corrosion resistance, heat resistance, good mechanical strength, and...
