Abstract

The invention provides a coating. The coating is prepared from, by weight, 1 part of nanoscale negative oxygen ion compound powder, 1 part of ozone water and 20-24 parts of micro dialysate. The nanoscale negative oxygen ion compound powder comprises 40-50 parts of tourmaline powder, 20-30 parts of titanium dioxide, 10-20 parts of zinc oxide and 1-10 parts of rare-earth complex. The micro dialysate comprises 15-20 parts of methyl sodium silicate, 20-30 parts of siloxane, 15-20 parts of polytetrafluoroethylene and 20-30 parts of water. The grain size of the nanoscale negative oxygen ion compound powder is smaller than 450 nanometers. The invention further provides a preparation method of the coating. The coating and the preparation method thereof have the advantages that according to the coating prepared through the preparation method, and through the cooperation of the nanoscale negative oxygen ion compound powder, the ozone water and the micro dialysate, the air purifying and bacterium resisting effects are good; negative oxygen ions can be released into the environment for a long time; the coating is good in abrasion resistance and toughness and high in bonding strength.

Description

Technical field [0001] The invention relates to paint, in particular to an antibacterial and negative oxygen ion-releasing paint and a preparation method thereof. Background technique [0002] As we all know, fresh air rich in oxygen-rich ions is a kind of air that is particularly beneficial to human health. Medical research has shown that it is the small particle size negative ions that have medical and health effects on the human body. Because only small-sized negative ions can easily penetrate the blood-brain barrier of the human body and exert their biological effects. The reason why air anions in nature create many longevity villages is because the proportion of small particle size anions is high. Small particle size anions form a negative ion bath environment over longevity areas due to their high activity and long migration distance. Relevant experts found that, The air in Bama contains a large amount of negative oxygen ions, which is one of the important reasons for the ...
