Abstract

The invention relates to the technical field of functional architectural coatings, and aims to provide a negative ion based paint. The negative ion based paint is prepared by mixing the following raw materials in parts by weight: 20-50 parts of synthetic resin emulsion; 5-30 parts of a negative ion additive; 15-30 parts of filler; 5-10 parts of an aid and 20-40 parts of deionized water; the negative ion based paint can be used as a main raw material for preparation of negative ion texture coatings, and is a new type coating ingredient product. By introduction of a negative ion additive into the negative ion based paint, a film forming matter of a final coating product has continued negative ion releasing function. At the same time, the preparation method of the negative ion based paint is simple and convenient, and can reduce the industrial production cost. In addition, the negative ion coatings prepared from the negative ion based paint have low VOC (volatile organic compounds) content, can greatly reduce the environmental pollution, are environmentally-friendly, can be used for residential buildings, commercial buildings, public buildings and other places, and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of functional architectural coatings, in particular to a negative ion base paint. 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 conduc...
