Zusammenfassung:The invention discloses modified vinyl ester resin and a preparation method thereof. The modified vinyl ester resin comprises the following raw materials by mass: 100 parts of vinyl ester resin; 0.5-5 parts of strong acid; 0.1 to 10 parts of a retarder; 10 to 100 parts of a low-volatility active solvent; the active components of the vinyl ester resin comprise styrene and alkyl acrylate-epoxy vinyl ester. The preparation method comprises the following steps: weighing the raw materials; preparing a modifier; adding a modifier; and adding a low-volatility active solvent. The strong acid is used as the initiator, styrene cationic polymerization can be pointedly initiated in the existing styrene-containing vinyl ester resin, styrene is converted into polystyrene to lose volatility, and the problems that in the application of the vinyl ester resin, styrene volatilization harms the health of operators and pollutes the environment are solved from the source. 本申请公开了一种改性乙烯基酯树脂及其制作方法。改性乙烯基酯树脂,包括如下质量比例的原料:乙烯基酯树脂:100;强酸:0
