Abstract

The invention relates to the technical field of functional building paint and provides negative ion-containing antibacterial haze-cleaning paint. Through raw material grinding and mixing, the negative ion-containing antibacterial haze-cleaning paint is prepared from 15-40 parts by weight of a film-forming emulsion, 8-30 parts by weight of a negative ion additive, 0.5-20 parts by weight of a silver ion additive, 5-35 parts by weight of a pigment and a filler, 5-15 parts by weight of an assistant and 20-50 parts by weight of deionized water. Through use of the negative ion additive, the coating film has a negative ion continuous-release function and can purify air so that a PM 2.5 concentration is reduced. The silver ion additive has lasting antibacterial and mildew-resistant functions. The preparation method is simple and convenient and is conducive to reduction of an industrial production cost. The negative ion-containing antibacterial haze-cleaning paint has low VOC (volatile organic compound) content, can greatly reduce environmental pollution, is environmentally friendly, 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 an anion antibacterial and haze-cleaning coating. Background technique [0002] Air pollution, especially PM2.5, which continues to exceed the standard, has seriously threatened the physical and mental health of residents. PM2.5 mainly causes damage to the respiratory system and cardiovascular system, including respiratory irritation, coughing, dyspnea, reduced lung function, aggravation of asthma, chronic bronchitis, arrhythmia, non-fatal heart disease, heart and lung disease patients die prematurely. The elderly, children, and patients with heart and lung diseases are sensitive groups to PM2.5 pollution. Meteorologists and medical experts believe that hazy weather caused by fine particles is even more harmful to human health than sandstorms. Particles with a particle size of 10 microns or more will be kept out of the human nose; particles with a par...
