Abstract

The invention relates to the technical field of functional building paint and provides negative ion texture paint. The negative ion texture paint is prepared from 20-40 parts by weight of negative ion basic paint, 60-80 parts by weight of quartz sand and 5-20 parts by weight of a thickening agent aqueous solution by mixing. The thickening agent aqueous solution contains 0.5-10 parts of solids and contains at least one of hydroxyethyl cellulose, an alkali swollen acrylic acid thickening agent and sodium-based bentonite. Through use of the negative ion additive, the coating film has a negative ion continuous-release function. The preparation method is simple and convenient and is conducive to reduction of an industrial production cost. The negative ion texture paint has low VOC (volatile organic compound) content, can greatly reduce environmental pollution, is environmentally friendly, has good negative ion release performances and decorativeness, is especially suitable for occasions such as residential buildings, commercial buildings and common buildings and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of functional architectural coatings, in particular to a negative ion texture coating. Background technique [0002] Negative ions play an important role in human health and have become an important parameter to measure air quality. After negative ions are inhaled into the human body, through the respiratory system and blood circulation system, they can improve the human respiratory function and endocrine function, promote metabolism, and enhance the body's immunity. At the same time, due to the neutralization effect of negative ions on positive ions, it can have the effects of deodorization, dust removal, anticorrosion, antibacterial, decomposition of formaldehyde and smog, and air purification. However, due to industrial waste discharge, garbage incineration, toxic chemical components, electromagnetic radiation pollution and other reasons in the urban environment, ions have dropped sharply, which is not c...
