Abstract

The invention relates to a glass fiber yarn impregnating compound as well as a preparation method and application thereof. The glass fiber yarn impregnating compound is prepared from the following materials: acetic acid, a silane coupling agent, modified waterborne epoxy resin, epoxy modified polyester, modified waterborne polyurethane and water. The preparation method comprises the following steps: adding part of water and acetic acid into a container, stirring until the pH value is 2.5-5, dropwise adding a silane coupling agent, and completely hydrolyzing to obtain hydrolysate; uniformly stirring the modified waterborne epoxy resin, the epoxy modified polyester, the modified waterborne polyurethane and water to obtain a resin mixed solution; and adding the resin mixed solution into the hydrolysate, adding water, and continuously stirring to obtain the glass fiber yarn impregnating compound. The environment-friendly glass fiber yarn impregnating compound provided by the invention can meet the operation requirements of forming, twisting, weaving and the like of glass fibers; after the silane coupling agent is applied to glass fiber yarns and before a composite material is prepared, the dielectric constant and strength requirements of the insulating composite material can be met without removing the silane coupling agent.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber yarn sizing agent and a preparation method and application thereof. Background technique [0002] Glass fiber (hereinafter referred to as glass fiber) is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Poor sex. Commonly used as reinforcement in composites, electrical insulation and thermal insulation. Glass fiber products are widely used in various fields of the national economy, among which electronics, transportation and construction are the three most important application fields, and also represent the development trend of the world glass fiber industry in the next few years. Baby bottle yarn is textile-type glass fiber or reinforced textile type. It is named after the yarn is shaped like a baby bot...
