Abstract
PURPOSE: To solve the difficulty of handling caused by the flotation of waste powder coating compound and to shorten the time and labor to treat the waste extremely, by treating a specific waste coating compound with a basic aqueous solution, dispersing the coating compound into water uniformly.
CONSTITUTION: A waste powder coating, comprising a resin system consisting of a resin (preferably thermosetting polyester type or thermosetting acrylic type) and a curing agent (e.g., diepoly compound) wherein at least one of them has a carboxyl group, is treated with a basic aqueous solution, and the powder coating compound is uniformly dispersed and suspended into water, to give a slurry. The pH of the basic aqueous solution dispersing the waste powder coating compound is maintained preferably at 7.3W10, methyl amine of organic type, ammonia of inorganic type, etc. may be cited a the basic compound used in the aqueous solution.
EFFECT: Contributing to the preservation of the encironment, save of resources, etc.
