Problems solved by technology

[0008] In practical application, there is a defect in the use of negative ion liquid sprays. The negative ion liquid with high content of negative ions has a strong acidic pH value, generally between 1.0-3.0, and is corrosive. When sprayed on the metal parts of automobiles and furniture, it will Oxidizing the surface of the metal will corrode the metal surface and affect the performance of the metal. In severe cases, it will cause safety hazards

Abstract

The invention discloses a negative ion air purification solution, which comprises the following components by weight: 80-96 parts of a negative ion mother liquor, 0.2-1 part of a dispersant, 3-10 parts of a weakly alkaline additive, 0.5-3 parts of a film-forming agent and 0.1-0.7 part of a film-forming additive. The negative ion air purification solution has pH of 6.0-7.2 and a negative ion concentration of 2000-30000 / cubic centimeter. The negative ion air purification solution is added with the dispersant and weakly alkaline additive, the dispersant has high calcium tolerance and can effectively prevent the deposition of various salts, and the weakly alkaline additive can neutralize the acidity of the negative ion mother liquor and make the pH of the negative ion air purification solutionapproach or reach neutral. The negative ion air purification solution does not corrode metal parts during use, and does not require constructors to wrap metal parts with a protective film in advance,thus saving labor and being safe.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an anion air purification solution. Background technique [0002] For air treatment, in addition to fresh air systems, air purifiers, and photocatalyst photocatalysis technologies, there are also negative ion air purification technologies, such as negative ion diatom mud technology, negative ion paint, negative ion tiles, negative ion sprays, etc. Among them, spraying negative ion liquid is a new material and the simplest method of passive purification. By spraying negative ion liquid on the surface of the carrier, a layer of transparent functional film is formed after the surface of the carrier is dried. Under the electric effect, it can release high-concentration negative ions for a long time, reaching the standard of the World Health Organization for clean air: no less than 1000-1500 per cubic centimeter. [0003] Negatively charged negative ion materials can neutralize positi...
