Negative-ion air purifying wall paint and production process thereof

Abstract

The invention discloses negative-ion air purifying wall paint and a production process thereof. The wall paint comprises the following components in parts by weight: 8-10 parts of nano negative-ion powder, 13-15 parts of talcum powder, 8-10 parts of micro silicon powder, 6-8 parts of titanium dioxide, 1-3 parts of an antifoaming agent, 2-3 parts of an emulsifier, 15-25 parts of ethyl acetate, 30-40 parts of a polyurethane emulsion, 20-30 parts of deionized water, and 3-5 parts of a thickening agent. According to the production process disclosed by the invention, the nano negative-ion powder isused as a negative-ion release source and used as a raw material for production of the wall paint, through the ultrasonic wave mixing action, the talcum powder, the micro silicon powder, the titaniumdioxide, the ethyl acetate, the polyurethane emulsion and the deionized water can be fully mixed, so that quality of a basic liquid of the wall paint can be improved; through homogenization dispersion by a homogenizer, the nano negative-ion powder can be uniformly mixed in the basic liquid to form the stable wall paint; and the wall paint disclosed by the invention facilitates long-term emissionof negative ions, can have a long-lasting effect on elimination of formaldehyde, purify air, and be beneficial to human health.

Description

technical field [0001] The invention belongs to the technical field of wall paint, and in particular relates to a negative ion air-purifying wall paint and a production process thereof. Background technique [0002] Wall paint is top paint, also known as latex paint, which is one of the main decorative materials used for walls in home decoration. It accounts for a considerable proportion of the basic decoration cost. Choosing a good quality wall paint is very important. Although the current wall paint can achieve the goal of environmental protection, due to the simple composition and poor functionality of the current wall paint, it cannot release negative ions after use, and cannot eliminate harmful gases such as formaldehyde in the environment, which is not conducive to people's health and has poor functionality. . [0003] For example, the patent application number CN201711015598.1 discloses an ecological wall paint that releases negative ions and purifies the air, incl...

Problems solved by technology

[0004] However, the above-mentioned scheme has the following defects in use: when producing wall paint, it is difficult to fully and evenly mix the components by simple mixing, which is not conducive to the uniform and long-term emission of negative ions by the negative ion source, which is harmful to formaldehyde and the like. Elimination of gas is not conducive to long-term protection of human health
