172nm excimer UV (ultraviolet) spraying skin-touch varnish and preparation and use methods of 172nm excimer UV spraying skin-touch varnish

The invention relates to the technical field of photocureable coatings, in particular to the field of IPC C09D 175, and more particularly relates to 172nm excimer UV spraying skin-touch varnish as well as a preparation method and a use method thereof. The coating comprises the following components in percentage by weight: 50-80% of polyurethane acrylic resin, 1-5% of organic silicon resin, 0.5-3% of a photoinitiator, 0.5-3% of matt powder, 0.5-3% of an auxiliary agent and the balance of a diluent. The photoinitiator comprises an MBF initiator and a TPO initiator, the weight ratio of the MBF initiator to the TPO initiator is 1: (2-3.5), and an excellent matte skin feeling effect can be obtained by using 172n m ultraviolet light for radiation. 本发明涉及光固化涂料技术领域，尤其涉及IPC C09D 175领域，更具体的，涉及一种172nm准分子UV喷涂肤感清面漆及其制备与使用方法。按重量百分比计，组分包括：聚氨酯丙烯酸树脂50-80％，有机硅树脂1-5％，光引发剂0.5-3％，哑粉0.5-3％，助剂0.5-3％，稀释剂补足余量。所述光引发剂包括MBF引发剂和TPO引发剂，所述MBF引发剂和TPO引发剂重量比为1：(2-3.5)，并使用172n m紫外光辐射，可获得极佳的哑光肤感效果。
