ら成るガラス繊維用サイズ剤に係る。As a result of extensive research, the present inventors discovered that the above-mentioned problems could be solved by limiting the ratio of each monomer component in a glycidyl (meth)acrylate-vinyl acetate copolymer to a specific range, and were able to complete the present invention. Ta. That is, the present invention provides a glycidyl (meth)acrylate component/
The present invention relates to a glass fiber sizing agent comprising an emulsion of a glycidyl (meth)acrylate-vinyl acetate copolymer in which the weight ratio of the vinyl acetate component is 3/97 to 30/70, preferably 5/95 to 15/85.

えると、共重合させるのが困難となる。In the sizing agent made of the copolymer emulsion of the present invention, if the weight ratio of glycidyl (meth)acrylate component/vinyl acetate component is less than 3797, the hardness of the copolymer film decreases, and the cohesiveness of glass fibers as a sizing effect decreases. The amount of fuzz decreases, and the amount of fuzz generation increases, and the adhesion between the copolymer film and glass decreases, resulting in a decrease in the boiling resistance of the GFRP molded product. On the other hand, if this value exceeds 30/70, it becomes difficult to copolymerize.
