いで品質を設計することが望まれている。(Prior Art and its Problems) Conventionally, it is known that toxic metal compounds such as lead compounds and chromium compounds are used in cationic electrodeposition paints in order to obtain high rust prevention properties. In particular, lead compounds not only passivate the paint film surface and improve rust prevention properties (but also act as curing catalysts that promote paint film formation). However, harmful metal compounds such as lead compounds These heavy metals may be dissolved and mixed into the wastewater generated from the line, and their content may exceed the official pollution control range for such heavy metals, potentially causing pollution.For this reason, these toxic metal compounds are not used. It is desirable to design with quality.

。(Means for Solving the Problems) In order to obtain a coating film with high rust prevention properties without using harmful metal compounds such as lead compounds, the present inventor has determined that the total amount of resin in the cationic electrodeposition paint should be increased. On the other hand, when 3 to 50% by weight of iron oxide was added, the formation of a coating film was greatly promoted and the coating surface became extremely dense. It has been found that a coating film can be obtained that maintains the same rust prevention properties as those of the conventional method and has excellent coating surface smoothness.

着塗料である。That is, the present invention is a non-polluting cationic electrodeposition paint in which iron oxide is blended in an amount of 3 to 50% by weight based on the total amount of resin.

が損なわれるので好ましくない。The blending amount of the acid/iron oxide used in the present invention is the above blending amount with respect to the total resin amount in the cationic electrodeposition paint, and the blending amount is 5 to 25%.
Vehicle volume % is preferred. If the amount of iron oxide is too small (less than 3% by weight), the rust prevention properties will decrease, whereas if it is too large (more than 50% by weight), the dispersibility will decrease and the stability of the paint will be impaired. So I don't like it.

る心配がなく無公害化を実現できた。(Effects of the Invention) According to the present invention, curing of the resin in the electrodeposition paint is promoted by incorporating an appropriate amount of iron oxide into the cationic electrodeposition paint. In this way, coating film formation is completed at a lower temperature and in a shorter time, resulting in a denser coating surface, which provides excellent rust prevention properties without the use of harmful metal compounds such as lead compounds and chromium compounds. Furthermore, there is no need to worry about harmful metal compounds being mixed into the wastewater, making it pollution-free.
