Abstract

The invention provides a glass fiber sizing agent. The glass fiber sizing agent is prepared from the following components in mass by percentage: 0.1 to 0.5% of coupling agent, 0.1 to 0.5% of lubricant, 2.0 to 12.0% of polyvinyl acetate emulsion, 1.0 to 6.0% of epoxy emulsion, 0.05 to 0.5% of crosslinking agent, 0.05 to 0.5% of pH adjusting agent, and 80.0 to 96.7% of water. The epoxy emulsion is abisphenol A type epoxy resin emulsion, and the polyvinyl acetate emulsion comprises a crosslinked polyvinyl acetate and a plasticized modified polyvinyl acetate, wherein the mass ratio of the crosslinked polyvinyl acetate and the plasticized modified polyvinyl acetate is (1 to 1) to (5 to 1). By using the sizing agent of the invention, the produced glass fiber yarn can not only improve the colorand breaking strength of the yarn, but also effectively improve the fluidity of the glass fiber and improve the compatibility with a matrix resin, and an SMC material for a sewage degrading tank obtained by reinforcing the glass fiber sizing agent can be improved has the advantages of uniform glass fiber distribution, smooth surface, high product yield and good mechanical properties.

Description

technical field [0001] The invention relates to the field of glass fiber production, in particular to a sizing for coating glass fibers, in particular to a glass fiber sizing for a sewage degradation tank and application thereof. Background technique [0002] Sewage degradation tank refers to the equipment specially used to treat domestic sewage made of synthetic resin as the matrix and glass fiber reinforced material. It is a composite material product actively promoted by the country. Because of its light weight, high strength, good toughness, corrosion resistance, bright colors, and mirror-like finish, it is widely used in chemical, petroleum, construction, environmental protection and other fields, and is mainly suitable for industrial enterprise living areas and urban residents' lives Purification and treatment of domestic sewage in residential buildings and other civil buildings. [0003] Early sewage degradation tanks were mostly formed by mechanical winding, which w...
