    • PURPOSE: A water-based paint is provided to be baked at a low temperature, to prevent fluorinated resin coating from being molten, and to prevent the generation of bubbles in a process of drying the paint due to pseudoplasticity. CONSTITUTION: A water-based paint is obtained by adding an acetylenic diol surfactant having a HLB value of less than 8 to the water-based paint. A polyether sulfone-based resin is mixed with water in a ratio of 90-150 parts by weight. An addition ratio of the acetylenic surfactant to the water-based paint is 0.5-8 parts by weight. A composite coating layer is comprised of a single or double coating layer and a coating layer which is formed using the water-based paint.
    • 目的:提供在低温下烘烤的水性涂料,以防止氟化树脂涂层熔化,并防止由于假塑性而使涂料干燥的过程中产生气泡。 构成:通过向水性涂料中加入HLB值小于8的炔属二醇表面活性剂得到水性涂料。 聚醚砜类树脂以90-150重量份的比例与水混合。 炔属表面活性剂与水性涂料的添加比例为0.5-8重量份。 复合涂层由单层或双层涂层和使用水性涂料形成的涂层组成。
