Abstract

The invention provides a glass fiber impregnating compound. The glass fiber impregnating compound comprises a coupling agent, a lubricant, an unsaturated polyester emulsion, a polyvinyl acetate emulsion, an epoxy emulsion, a polyurethane emulsion, a pH value regulating agent and water. The content of each of the above components is studied in the invention. The glass fiber impregnating compound provided by the invention can change the physical and chemical properties of the surface of glass fiber, effectively improves the flowability and splitting performance of the glass fiber, and enhances the compatibility of the glass fiber with matrix resin; and a prepared SMC product has the characteristics of uniform glass fiber distribution, a smooth surface without lines, good mechanical properties, etc. The invention also provides application of the glass fiber impregnating compound to manufacturing of grid beams.

Description

technical field [0001] The invention relates to the field of sizing agents, in particular to a glass fiber sizing agent and its application. Background technique [0002] Sheet molding compound (SMC) is a molding compound for dry manufacturing unsaturated polyester resin FRP products. It was first introduced by Bayer in Germany in the early 1960s. Around 1965, the United States and Japan successively developed this process, and then it quickly entered various application fields because of its excellent productivity, strength characteristics, heat resistance, and surface properties. [0003] As people's requirements for the appearance and decoration of SMC products become more and more diverse and strict. Uniform color tone inside and outside, excellent appearance effect, SMC products with rich color and long-lasting color have become one of the main directions of current SMC research and application. [0004] The physical performance requirements for general coloring SMC p...
