Glass fiber antistatic composition and application thereof

Abstract

The invention relates to a glass fiber antistatic composition, which belongs to the technical field of glass fiber surface treatment. The composition comprises 1-35 parts by mass of an antistatic agent, 55-99 parts by mass of a polar organic solvent, and 0.02-1 part by mass of a wetting agent, wherein the wetting agent is an alkynediol ethyoxyl compound; the polar organic solvent has volatility. The invention also relates to application of the antistatic composition in preparation of antistatic glass fibers. Compared with the prior art, the composition has advantages that the composition can achieve uniform coating of the antistatic agent, the antistatic performance of the glass fibers is remarkably improved, and the problem that the product quality is influenced due to the fact that the dispersity of the glass fibers is reduced as moisture of an existing antistatic agent is not easy to volatilize can be avoided.

Description

technical field [0001] The invention belongs to the technical field of glass fiber surface treatment, in particular to a glass fiber antistatic composition and the application of the antistatic composition in preparing antistatic glass fibers. Background technique [0002] Static electricity is generally formed through the redistribution of charges caused by friction. Its hazards are caused by electrostatic force and electrostatic sparks. The most serious electrostatic discharge can cause fire and explosion of combustibles, resulting in major casualties and property damage accidents. The accumulation of static electricity and materials It is related to the nature of the material, the better the insulation performance of the material, the easier it is to generate static electricity. [0003] Glass fiber is a composite material with good insulating properties. In order to reduce or avoid the accumulation of static electricity on its surface, it is usually coated with a thin la...

AI Technical Summary

Problems solved by technology

Since most antistatic agents contain organic groups with relatively large molecular weight, the effect of dispersion in water is not very good, and the compatibility between water and the sizing coating on the surface of glass fiber is not high, so the coating effect is not ideal; and because Due to the effect of surface tension, the antistatic agent is easy to accumulate on some places on the surface of the glass fiber, and the rest of the place cannot be effectively coated; the above defects lead to poor antistatic effect of the product

In addition, because the moisture is not easy to volatilize, the processing time and difficulty of the subsequent process are increased, and the production efficiency is greatly reduced.
