A kind of preparation method of glass fiber sizing agent

Abstract

The invention discloses a preparation method of a glass fiber impregnating agent. The method includes the following specific steps of 1, preparing a hydrolysis solution; 2, preparing a dispersion liquid; 3, preparing a lubricant liquid; 4, preparing a mixed solution, wherein a bonding agent, the lubricant liquid, an antistatic agent and an epoxy emulsion are sequentially added into the dispersionliquid and stirred; 5, conducting dilution and homogenizing, wherein the mixed solution is added into soft water to obtain a diluent, and the diluent is placed in a homogenizer for being stirred and refined uniformly to obtain a finished product. The lubricant is processed from an emulsion to the liquid and then added, an active water molecule additive is added into the impregnating agent, and thesolution is added into the homogenizer, so that the effect of adjusting the performance of epoxy aqueous solution series is achieved, the surface energy of an interface between glass fiber monofilaments and the impregnating agent is reduced, the adsorption of the raw filaments is easier in an impregnating process, the adsorption surface is more uniform, the disadvantages of high shutdown rate andeasy damage of fibers are avoided, and economic benefits of a producer can be increased.

Description

technical field [0001] The invention relates to the field of glass fiber production, in particular to a preparation method of a glass fiber sizing agent. Background technique [0002] Glass fiber is an inorganic non-metallic material with superior performance. Glass fiber products have excellent strength, rigidity, portability, corrosion resistance, durability, weather resistance and other characteristics. It is made of glass balls or waste glass. Manufactured by high-temperature melting, wire drawing, winding, weaving and other processes, the diameter of its single filament is several microns to more than 20 microns, which is equivalent to 1 / 20-1 / 5 of a hair. Fiber precursors are composed of hundreds or even thousands of monofilaments, and are widely used in construction, transportation, electronics, electrical, chemical metallurgy, environmental protection, national defense and other fields. Sizing agents are a key factor in the production of these products. [0003] At ...

AI Technical Summary

Problems solved by technology

[0003] At present, the sizing agent used for 7781# glass fiber cloth generally adopts epoxy aqueous solution series, and the lubricant is in the form of emulsion. This kind of sizing agent is easy to cause the line wheel to stick to the original wire during the wire drawing process, resulting in high shutdown rate and easy fiber damage. Disadvantages, which reduce the economic benefits of glass fiber producers
