DIRECT ROVING IMPREGNATION AGENT FOR GLASS FIBER MULTI-AXIAL FABRIC, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

摘要

Disclosed is a direct roving impregnation agent for a glass fiber multi-axial fabric. The impregnation agent contains the following components, and the percentage of the solid mass of each component to the total solid content of the impregnation agent is shown as follows: 0.1-5.0% of a first silane coupling agent; 2.5-11.0% of a second silane coupling agent; 3.0-20.0% of a first film forming agent; 45.0-75.0% of a second film forming agent; 0-5.0% of plasticizer; 0.2-4.0% of a first lubricant; 5.0-20.0% of a second lubricant; and 0.01-3.0% of a pH value regulator, the first film forming agent being a multifunctional epoxy emulsion, and the second film forming agent being a small-molecular-weight liquid epoxy emulsion. The impregnation agent has a suitable dissolution rate in a resin and good compatibility with the resin; and wind blades produced by the glass fiber multi-axial fabric produced by the impregnation agent have the advantages of stable mechanical strength, good fatigue resistance, long service life, etc.
