Preparation process of negative oxygen ion thermosetting powder coating for purifying air

Abstract

The invention relates to a preparation process of a negative oxygen ion thermosetting powder coating for purifying air, and relates to the technical field of coating preparation. The preparation process comprises the steps: when monazite powder and water are mixed and then subjected to pickling for a first preset duration, obtaining the pH value variation of a mixed material in a mixed reaction kettle; determining whether pickling is completed or not according to a comparison result of the pH value variation and a preset pH variation, bleaching when it is judged that pickling is completed, and adjusting ultrasonic vibration frequency when it is judged that pickling is not completed, so as to accelerate pickling of the monazite powder in the mixed reaction kettle; and during bleaching of the mixed materials, according to a comparison result of the color difference value and a preset color difference value, determining whether bleaching is completed or not, and when the bleaching is not completed, adjusting the adding amount of calcium hypochlorite or oxalic acid, so as to further improve the control precision of the pickling process of the mixed reaction kettle, and further improve the quality of the prepared negative oxygen ion thermosetting powder coating.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a preparation process of air-purified negative oxygen ion thermosetting powder paint. Background technique [0002] Medical experiments have confirmed that negative oxygen ions can activate cells, purify blood, restore fatigue, stabilize the autonomic nervous system, enhance disease resistance, inhibit tumor cells, resist radioactive substances and electromagnetic radiation, and have analgesic effects. Improve allergies. [0003] As a new type of coating, negative oxygen ion coatings can release negative oxygen ions indoors to purify the indoor air. The existing technology for preparing negative oxygen ion coatings and the prepared negative oxygen ion coatings can make the coatings It achieves a high release of negative oxygen ions when used. [0004] However, in the process of preparing negative oxygen ion coatings in the prior art, the waste liquid after pickling an...
