Abstract

The invention discloses a glass fiber impregnating compound and a preparation method thereof. The preparation method comprises the following steps: sequentially adding a coupling agent B, a compatilizer, glacial acetic acid, a coupling agent A, a lubricating agent, a main film forming agent and a moisturizing agent to deionized water; fully stirring; carrying out a reaction to obtain the impregnating compound product; the impregnating compound product comprises the following components in percentage by weight: 0.05-0.2% of glacial acetic acid, 0.2-0.6% of a coupling agent A, 0.4-0.9% of a coupling agent B, 0.2-0.5% of a compatilizer, 0.4-0.8% of a lubricating agent, 15-25% of a main film forming agent, 0.1-0.4% of a moisturizing agent, and the balance of deionized water. With the adoptionof the impregnating compound, the technical problems of low stability, low impregnating effect and low impregnating efficiency of a conventional impregnating compound can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of glass fiber surface treatment, and in particular relates to a glass fiber sizing agent and a preparation method thereof. Background technique [0002] The sizing agent is an indispensable surface treatment material in the production of glass fiber. The quality of the glass fiber and the variety of varieties depend to a large extent on the sizing agent. Without a good sizing agent, it is impossible to produce High-quality, wide variety of fiberglass. [0003] At present, there are many kinds of glass fiber sizing agents on the market, but these glass fiber sizing agents have the problem of uneven mixing of the formula, which not only has poor stability, but also has a serious impact on the wetting effect. In addition, when the glass fiber is infiltrated, due to its poor dispersion, it cannot be infiltrated quickly and completely, the infiltration efficiency is low, and the interface is not well bonded, wh...
