Embodiment Construction

[0021] The present invention is specifically described below through specific examples, but the protection scope of the present invention is not restricted by the following examples.

[0022] The specific formulation of the wetting agent is shown in the following table (the data in the table are the percentages of the weight of the components in the total mass of the wetting agent): the coupling agent is a silane coupling agent produced by Tengjiao Company, and the product grades are KH-570 ;

[0023] The lubricant is a mixture of water-soluble modified alkyl compound emulsion and cationic lubricant, both of which are purchased from Yixing Zhonghe Chemical Co., Ltd., and the product grades are BX005 and 6760 respectively;

[0024] Described film-forming agent polyvinyl acetate emulsion, specifically Airflex 410, U.S. Air Products and Chemical Company;

[0025] Described film-forming agent polyester emulsion, RD-1135B, is purchased from U.S. PPG company;

[0026] The pH regul...

Abstract

The invention discloses an enhanced glass fiber sizing agent and a preparation method thereof. During the preparation, coupling agents, glacial acetic acid, lubricating agents, main film forming agents and wetting agents are sequentially added into deionized water; after sufficient stirring and reaction, a finished product of the sizing agent is obtained. The finished product is prepared from 0.05to 0.2 percent of glacial acetic acid, 0.2 to 0.6 percent of coupling agents A, 0.4 to 0.9 percent of coupling agents B, 0.4 to 0.8 percent of lubricating agents, 15 to 25 percent of main film forming agents and the balance of deionized water. By using the sizing agent provided by the invention, the technical problems of poor stability, poor sizing effect and low sizing efficiency of a conventional sizing agent 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...
