Dope with negative ion function for air purification, and prepartion method

Abstract

This invention discloses a method for producing anion-generating paint for air purification. The paint uses acrylic acid emulsion, additive, titanium dioxide, heavy calcium carbonate, kaolin, light calcium carbonate, talcum powder, dispersant, antifoam, thickener, film-forming agent and water as the raw materials. The method comprises: mixing the raw materials, stirring, grinding by three rollers, stirring, regulating the color, filtering and packaging. The paint can permanently generate anions so that the concentration of indoor anions can reach the requirement of human bodies, thus can be used for indoor sterilization and air purification, and is good for human health.

Description

technical field [0001] The invention relates to a building material, in particular to a negative ion air-purifying functional paint and a preparation method thereof. Background technique [0002] Coating is a commonly used building material, it is mostly used in the decoration of buildings, such as interior wall paint for interior decoration of buildings, and also for decoration of exterior walls of buildings With the advancement of technology in the construction field, there are more and more functional coatings. These functional coatings are usually added with some functional substances in the coating composition, so that the coating can be used in general On the basis of decoration, it also has a certain functional effect, and the recently emerging paint with the addition of substances that release negative air ions is one of them. [0003] With the rapid development of our country's national economy and the substantial improvement of people's living standards, a large n...

Problems solved by technology

[0003] With the rapid development of our country's national economy and the substantial improvement of people's living standards, a large number of wood-based panels, construction glue, artificial carpets, paints, paints, and more and more household appliances have been invited into the home during the decoration process. While decoration and facilities provide people with enjoyment and convenience, they also bring indoor air pollution and a decline in indoor air quality. Especially after many families adopt air conditioners, the concentration of negative ions in the indoor air drops sharply, which is far below The concentration of negative ions required by the human body, and then lead to the occurrence of various diseases, causing the human body to have symptoms such as fatigue, headache, dizziness, memory loss, etc., and serious canceration, especially for the elderly and children, in order to avoid indoor negative ion concentration The drawbacks brought about after the decline, the existing way is to install a negative ion generator indoors, through the negative ions produced by the negative ion generator, to increase the indoor air negative ion concentration, but this method requires both indoor In the limited space, it needs to increase the cost of equipment and power consumption, and the operation of switching on and off every day, which brings inconvenience to people's use

Therefore, a kind of air-cleaning functional coating that contains negative ion coating additive just arises at the historic moment, but, existing negative ion functional coating adopts light-activated mode to produce negative air ion usually, and this method must just could produce negative air ion under illumination, and Expensive, which affects the popularization and application of negative ion functional coatings
