Two-component recyclable surface printing matting oil for BOPP (biaxially-oriented polypropylene) treatment-free surface printing

The invention relates to the technical field of matting oil preparation, in particular to two-component recyclable surface printing matting oil for BOPP (biaxially-oriented polypropylene) treatment-free surface printing. The matting oil comprises a PVB connecting material, polyurethane resin, a filler, a wetting dispersant, a curing agent, an adhesion promoter, ethanol, isopropanol, ethyl ester, n-propyl ester and matting powder, the matting oil prepared by the method can be recycled, the use cost is greatly reduced, and meanwhile, the matting oil can be printed on a BOPP (Biaxially-Oriented Polypropylene) non-treated surface and has 95% of non-shedding adhesion, and the matting oil has a good application prospect. The market prospect is excellent. 本发明涉及消光油制备技术领域，具体关于一种用于BOPP免处理面印刷的双组份可循环使用表印消光油；该消光油中包含PVB连接料、聚氨酯树脂、填料、湿润分散剂、固化剂、附着力促进剂、乙醇、异丙醇、乙酯、正丙酯和消光粉，通过本方法制备的消光油可循环使用，大大降低了使用成本，同时能满足印刷在BOPP免处理面且有95％不脱落的附着力，具有优异的市场前景。
