Problems solved by technology

At present, in the decoration and decoration materials of children's rooms, a large amount of organic solvents are used in wall coatings, which contain a large amount of organic volatile compounds (VOC), heavy metals, alkylphenol polyoxyethylene ethers (APEO) and formaldehyde, etc., and the paint The antibacterial performance is poor. In the moldy and rainy season, a large number of microorganisms are easy to breed on the wall. However, children's immunity is weaker than that of adults, and they are in the growth and development period. The resistance to bacteria or various harmful substances is relatively low. Children and this type of wall Direct contact with the surface paint can easily cause allergies and cause hidden dangers to children's health

Abstract

The invention discloses child aldehyde-free antibacterial water-based diatom coating and a preparation method thereof. The child aldehyde-free antibacterial water-based diatom coating takes deionizedwater as a solvent and does not contain organic solvents, titanium dioxide, nano-ZnO loaded diatomite and nano-WO3 loaded diatomite are added, formaldehyde is further effectively absorbed and decomposed, allergy harm of the coating to children is effectively reduced and eliminated, and the coating is safe and environmentally friendly; and nano ZnO and nano WO3 compounding is adopted in the diatomite, and thus the good synergistic antimicrobial and durable antimicrobial performance is achieved. By reasonably adjusting the proportion of all components, the compatibility of all the components ofthe coating is good, the stability of the coating is improved, the mechanical properties of a coating film can be effectively improved, and the coating is resistant to scratching and scrubbing.

Description

technical field [0001] The invention relates to the technical field of water-based diatom mud coatings, in particular to a formaldehyde-free antibacterial water-based diatom mud coating for children and a preparation method thereof. Background technique [0002] In recent years, with the refinement of the market, more and more users have paid more and more attention to the environmental protection of home decoration materials. Among children's room decoration and decoration materials, materials with poor environmental protection have greater safety hazards, so , The environmental protection and safety of wall coatings in children's rooms are becoming the focus of consumers' attention. At present, in the decoration and decoration materials of children's rooms, a large amount of organic solvents are used in wall coatings, which contain a large amount of organic volatile compounds (VOC), heavy metals, alkylphenol polyoxyethylene ethers (APEO) and formaldehyde, etc., and the pai...
