摘要： The present invention provides a recyclable cold curing aqueous coating composition, comprising (a) an oxidative-polymerizable, modified epoxy resin with an acid value of 25 to 60, comprising 20 to 70 percents by weight of an epoxy resin based on the total weight of said modified epoxy resin, of which a particle size is not more than 200 nm in an aqueous medium, (b) an anticorrosive pigment and/or an ampholytic metal oxide and (c) a drier. The recyclable cold curing aqueous coating composition of the present invention can provide a coating film having improved water resistance and corrosion resistance, and repeatedly reuse by recycling and readjusting. The present invention also provides a method for recycling the cold curing aqueous coating composition.

摘要： Material balance is maintained in a recycling system for aqueous paint by controlling a liquid amount within the recycling system while spray-coating an article. A recycling method includes: coating an article with aqueous paint in a water-curtain-type coating booth; collecting an over-spray paint, that does not adhere to the article, by virtue of a water curtain; sending a collected solution of paint and water to a condensation bath through a booth circulation water bath; separating this solution by an ultra-filtration apparatus into condensed paint and filtrate, with the condensed paint being transferred to a paint tank; and removing condensed paint from the paint tank, if necessary for adjustment of aqueous paint, followed by coating this aqueous paint onto an article, wherein a total amount of liquid present within the recycling system is controlled to be constant during spray-coating of an article.
摘要翻译：通过在喷涂物品的同时控制回收系统内的液体量，将物料平衡保持在用于水性涂料的再循环系统中。回收方法包括：将水性涂料的物品涂布在水帘式涂布室中; 通过水幕收集不附着物品的喷涂漆; 通过展位循环水浴将收集的油漆和水溶液送至冷凝水; 将该溶液通过超滤装置分离成浓缩的油漆和滤液，将冷凝的油漆转移到油漆罐中; 并且如果需要调整水性涂料，然后将该水性涂料涂覆到制品上，则从油漆罐中除去浓缩的油漆，其中在制品的喷涂过程中将存在于再循环系统内的液体的总量控制为恒定。

摘要： The present invention provide a recyclable cold curing aqueous coating composition comprising an acrylic group-modified epoxidized ester resin with acid vale of 25 to 60, which is formed from an epoxy resin (a), a fatty acid (b) and an ethylenically unsaturated monomer (c) in a component (a)/component (b)/component (c) weigh % ratio of 20 to 70/20 to 50/3 to 50, the sum of (a), (b) and (c) being 100 weight %, and a method for reusing it. For the method of the present invention, the coating composition has improved recycling properties by optimizing the properties such as acid value of the resin, the pH of a collecting solution for use to collect the coating composition and a content of a hydrophilic solvent in the collecting solution.
