Title
(EN) Water-based coating composition
(ZH) 一种水性涂料组合物
Abstract
(EN) The invention relates to a water-based coating composition, preparation and application of the composition, a two-component coating system containing the composition and application of the two-component coating system, and a product obtained by coating with the composition or the two-component coating system. The water-based coating composition comprises: an aqueous UV resin; a nano silicon oxide compound subjected to silane treatment; and a photoinitiator. The solid content of the water-based UV resin per kilogram contains not less than 3 mol of olefinic unsaturated groups, and the weight ratio of the solid content of the nano silicon oxide compound to the solid content of the water-based UV resin is 11: 20 to 73: 100. A coating formed by the water-based coating composition has high hardness and good adhesive force, and is especially suitable for electronic, electrical and communication equipment in the 5G field.
(ZH) 本发明涉及一种水性涂料组合物、组合物的制备和应用、包含该组合物的双组分涂料体系及其应用，以及使用该组合物或双组分涂料体系涂覆得到的制品。该水性涂料组合物包含：一水性UV树脂；一经过硅烷处理的纳米氧化硅化合物；和一光引发剂；每千克所述水性UV树脂的固体分包含不少于3mol的烯属不饱和基团，所述纳米氧化硅化合物的固体分与所述水性UV树脂的固体分的重量比为11∶20‑73∶100。本发明的水性涂料组合物形成的涂层具有高硬度和良好的附着力，特别适用于5G领域的电子、电气和通信设备。
