The invention relates to the field of C09D133/00 of IPC classification, in particular to a water-based folding-resistant highlight composite coating and a preparation method thereof. The water-based folding-resistant high-brightness composite coating is prepared from the following raw materials in parts by mass: 80 to 120 parts of epoxy modified composite emulsion, 10 to 50 parts of organic acid resin, 50 to 300 parts of diluent and 4 to 15 parts of functional additive. The prepared coating has good folding resistance, corrosion resistance and high laser brightness, the adhesion force of the coating and a PET corona base film is effectively improved, and the coating is suitable for being popularized in the field of packaging materials and has wide development prospects. 本发明涉及IPC分类的C09D133/00领域，尤其涉及一种水性耐折高亮复合涂料及其制备方法。一种水性耐折高亮复合涂料以质量份计，原料包括以下成分：环氧改性复合乳液80～120份，有机酸树脂10～50份，稀释剂50～300份，功能助剂4～15份。本申请制备的涂料具有良好的耐折性，防腐蚀性以及较高的镭射亮度，并且有效提高了其与PET电晕基膜的贴附力，适宜在包装材料领域推广，具有广阔的发展前景。
