Problems solved by technology

Another example is CN03126626.6, which uses rutile titanium dioxide and anatase silicon dioxide to prepare a super-weather-resistant, stain-resistant low-pollution coating with silicon-acrylic emulsion. Insufficient air purification
The reason is that these patents mainly modify traditional coatings by adding nano-type antibacterial particles. These nanoparticles have different degrees of poor dispersion, large particle aggregation and migration problems in coating configuration, storage and use, making it difficult to play their role. , and cause an increase in coating costs

Abstract

The invention relates to an environment-friendly antimicrobial odorless healthy latex paint applicable to internal and external wall application. The environment-friendly antibacterial paint is composed of inorganic / nanoparticle modified acrylate emulsion, nano metal oxide, anatase nano titanium dioxide, aluminum oxide, pigment and filler, thickening agent, dispersant, leveling agent and film-forming assistant. By using the dual functions of the inorganic nanoparticle / modified acrylate composite emulsion and nano metal oxide, the paint is endowed with high performance, and has the functions of environment protection, sterilization, air cleaning, deodorization and the like. The paint has the characteristic of excellent application property, and is antimicrobial, ecological and environment-friendly.

Description

technical field [0001] The invention relates to an environment-friendly antibacterial, odor-free and healthy latex paint suitable for painting interior and exterior walls. Background technique [0002] With the rise of modern high-rise buildings, the requirements for water resistance, anti-aging, stain resistance and self-cleaning performance of coatings are getting higher and higher. For outdoor decoration and high-rise buildings exposed to the outdoors for a long time, it is hoped that the coating has excellent stain resistance anti-aging and self-cleaning properties; at the same time, with the enhancement of environmental protection awareness, it is required that the coatings be green, have no harm to people's health and the environment, and are antibacterial, sterilizing, and purify the air. Therefore, high-performance, green and healthy water-based Coatings become the focus of research. [0003] At present, green environmental protection coatings and nano coatings have...
