Problems solved by technology

However, due to the low photocatalytic efficiency of photocatalytic materials in the visible light field, and the low life and efficiency of photocatalytic materials, it cannot meet the purification and treatment requirements of serious chemical pollutants in building interiors.
Adsorption-type active materials are passive purification materials that only rely on adsorption to treat pollutants. First, there is a problem of adsorption saturation. Second, the adsorbed pollutants will be released under certain conditions, so it has not really solved the problem of indoor chemical pollution.
In addition, in terms of the permeability of small molecule gases (such as formaldehyde, toluene, etc.) No related research work has been carried out so far

Abstract

The invention discloses a self-adsorption interior-wall-decoration environment-friendly composite coating material as well as a preparation method and an application thereof. The coating material is a multiple-layer coating material and consists of a bottom-layer coating material and a surface-layer coating material, wherein the bottom-layer coating material consists of a cementing material, a mineral material, a basic material and necessary auxiliary materials which react with one another so as to form an interlaced network structure; the surface-layer coating material consists of a resin material, a mineral material, an inorganic material and an additive which react with one another so as to form a loose network structure full of tiny holes. According to detection, the composite coating material, which is a novel self-adsorption interior-wall-decoration environment-friendly composite coating material for environment-friendly building interiors, is efficient, long-acting and environment-friendly and integrates functions of purification, permeation, diffusion and the like.

Description

technical field [0001] The invention belongs to environmental protection functional materials in the field of building materials, in particular to a novel, environment-friendly composite coating material for building decoration and decoration and a preparation method thereof. In addition to the basic functions of decoration and decoration of building coatings, the coating also has high-efficiency It has the functions of removing indoor chemical pollutants, purifying the air, and allowing small molecule gases to pass through efficiently. Background technique [0002] People spend more than 85% of their lives indoors. Therefore, indoor air quality is closely related to human health and living comfort. The presence of pollutants in the environment directly endangers human health, life expectancy and safety. Formaldehyde has always been the primary pollutant in the indoor environment. As early as 1995, formaldehyde was identified as a carcinogen by the International Agency for R...
