Multifunctional interior wall coating and preparation method and application thereof

Abstract

The invention belongs to the technical field of coatings and relates to a multifunctional interior wall coating and a preparation method and application thereof. The multifunctional interior wall coating comprises a material A-front-end dispersed slurry, a material B-composite nanometer zinc oxide prefabricated slurry and a material C, wherein the material A-front-end dispersed slurry comprises adry film mildew inhibitor, namely, a mildew inhibitor containing BCM, an OIT and a diuron; the material B-composite nanometer zinc oxide prefabricated slurry comprises the following raw materials in percentage by weight: 45 to 55 percent of water, 0.1 to 0.4 percent of first thickener, 0.01 to 0.2 percent of first pH regulate agent, 0 to 0.2 percent of first preservative, 0.1 to 0.4 percent of first defoaming agent, 1.0 to 3.0 percent of first dispersant, 0.1 to 0.5 percent of first wetting agent and 40 to 60 percent of nano-composite zinc oxide powder. At that same time, the coating has the multifunctional characteristic of mildew-proof and antibacterial, yellowing-resistant, high-efficient removal of formaldehyde, toluene, TVOC and other harmful gas shelf, and has low odor effect.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a multifunctional interior wall coating and its preparation method and application. Background technique [0002] With the development of social economy and the improvement of people's living standards, people pay more and more attention to their own health, have higher and higher requirements for living environment, and higher and higher requirements for interior decoration materials. The quality of indoor air quality directly affects the health of the human body, and interior wall coatings, as an important part of building decoration materials, play an important role in establishing a beautiful, comfortable and healthy living environment, so the more environmentally friendly functional building interior wall coatings are are getting more and more attention. [0003] In recent years, relevant companies or researchers have done a lot of exploratory research work on ...

Problems solved by technology

However, the existing products or technologies cannot guarantee the full dispersion of nano-components, and fail to give full play to the due effects of nano-components

On the one hand, the purification performance and actual purification effect of traditional products or functional interior wall coatings that can remove harmful gases are very limited; on the other hand, traditional functional interior wall coatings have single functions and can play a single role

Therefore, it has become a market trend to study coating products with anti-mildew, high-efficiency formaldehyde removal and indoor TVOC functions. However, existing coatings with similar functions will produce yellowing, and the anti-mildew effect cannot achieve "mildew-proof and anti-mildew" or The effect of "anti-mold and antibacterial", and the clean taste or low odor are not satisfactory, so that its practical application is greatly limited

[0004] Therefore, how to overcome the problems existing in the existing coatings, that is, the effect of "mildew and mildew prevention" cannot be achieved, the coating itself cannot achieve clean or low odor, and cannot efficiently remove formaldehyde and various VOCs in the room. The problem of not being able to achieve the anti-yellowing effect is a major challenge for researchers in this field
