Abstract

The invention relates to a polyester resin impregnating agent which is widely suitable for glass fiber enterprises. The polyester resin impregnating agent is prepared by the following raw materials inparts by weight: 100-200 of dicyclopentanediol, 90-180 of neopentyl glycol, 90-200 of trimethylolpropane, 120-200 of dihydromethyl propionic acid and 70-160 of tetrafluorophthalic anhydride. The invention has high hardness, toughness, tensile strength, bending strength and dissolubility in styrene, trends to refinement in the synthesizing process, improves the feed and temperature control precision and realizes numerical control; the synthesizing process is carried out by from a one-step method to a multistep method so as to enable a molecule chain structure of a polyester film forming agentto be more reasonable and regular, and the molecular weight is as high as more than ten thousand; and the polyester resin impregnating agent is widely applied to the impregnating agent of chopped strand mat, jet, BMC and SMC yarns.

Description

technical field [0001] The invention relates to a sizing agent, in particular to a polyester resin sizing agent, which is widely applicable to glass fiber enterprises. Background technique [0002] At present, a considerable number of small and medium-sized fiberglass companies do not have the ability to develop and debug sizing formulations. Old formulas such as paraffin-type sizing, 711, and 811 sizing are still in use for decades, and the quality of glass fiber products is at a high level. Loops in the low level range. However, some high-end glass fiber products that are urgently needed and promising in the market, such as roving for LFTP, high-quality chopped yarn, jet, SMC yarn, and winding roving for reinforcing high-pressure epoxy pipes, are still in comparison with foreign products. big gap. Although the production of small and medium-sized crucible glass fibers has the advantages of small batches, quick replacement of varieties, and no need for splitting and split...
