The invention discloses a glass fiber impregnating compound. The glass fiber impregnating compound comprises effective components and water, the solid content of the impregnating compound is 5.5-12%; the effective components comprise a coupling agent, a wetting agent, an auxiliary agent, a lubricant, a film-forming agent and a pH value regulator; the impregnating compound comprises the following effective components in percentage by mass: 12-17% of a coupling agent, 2-4.5% of a wetting agent, 0.05-0.5% of an auxiliary agent, 7-14.5% of a lubricant, 60-74% of a film-forming agent and 3-5.5% of a pH value regulator, wherein the solid mass of the coupling agent accounts for 12-17% of the total solid mass of the impregnating compound; wherein the film-forming agent is one or a combination of more of epoxy resin emulsion and modified epoxy resin emulsion. A glass fiber product produced by coating the glass fiber impregnating compound has the characteristics of low resin absorption amount, less hairiness and good i
