Water-based paint coating with air purification function and preparation method of water-based paint coating

Abstract

The invention provides a water-based paint coating with an air purification function. The water-based paint coating is prepared from the following components in parts by weight: 10 to 20 parts of a first air purification functional component, 8 to 14 parts of a second air purification functional component, 5 to 10 parts of a titanate coupling agent, 90 to 150 parts of water-based resin, 30 to 50 parts of water, 0.5 to 1 part of a de-foaming agent and 0.5 to 1.5 parts of a dispersing agent, the first air purification functional component is prepared from 8 to 10 parts of three-dimensional network graphene, 1 to 3 parts of nano silicon dioxide, 1 to 3 parts of nano titanium dioxide, 0.3 to 0.5 part of nano manganese dioxide and 10 to 20 parts of absolute ethyl alcohol; and the second air purification functional component is prepared from 5 to 8 parts of shell powder, 0.8 to 1.5 parts of tourmaline and 0.2 to 0.5 part of sepiolite. The water-based paint coating prepared by the preparation method disclosed by the invention is sufficient in coating loading, firm in combination, high and lasting in purification performance, capable of better purifying air and more widely applied to decoration materials.

Description

technical field [0001] The invention relates to the technical field of water-based paint preparation, in particular to an air-purifying functional water-based paint and a preparation method thereof. Background technique [0002] As an indispensable material in decoration, paint is more and more important for its environmental protection and safety. Water-based paint is a paint with water as the diluent. It does not contain benzene, toluene, xylene, formaldehyde, and free TDI toxic heavy metals. It is non-toxic, non-irritating, harmless to the human body, and does not pollute the environment. It has the characteristics of good flexibility, fast drying, and convenient use, and has attracted people's attention. [0003] Indoor decoration materials will release formaldehyde, benzene, xylene and other harmful substances, causing damage to people's respiratory system and nervous system, reducing human immunity and quality of life, and seriously threatening people's health.

Problems solved by technology

People often use physical adsorption or chemical decomposition to purify the air. The usual physical adsorption materials mainly include activated carbon. Due to its large specific surface area, activated carbon can easily absorb harmful gases in the air, but its adsorption capacity is limited, and only Adsorption does not decompose harmful substances; in the research of chemical decomposition, the characteristics of limited decomposition amount and slow decomposition speed are often referred to, and some additional conditions such as light and PH value are required, and the purification performance is not sustainable. For example, the patent CN1021101008A discloses Soaking inorganic adsorption materials in 5-20% inorganic oxidant aqueous solution for 18-36 hours and then drying can improve the purification effect; but only by soaking to load oxidant, the load is not sufficient and firm, and the purification performance shown cannot last
