Abstract

The invention provides dust absorption and dust falling decorative paint for an internal wall and a preparation method thereof, belonging to the building material field. The paint in every 100 weight portion at least comprises 1 to 40 weight portions of a sorbing material, 2 to 15 weight portions of a nanometer material and 20 to 60 weight portions of an inorganic filling material. The paint which takes a crystalline material with the pyroelectric effect such as tourmaline, triglycine sulfate, and lead lanthanum zirconate titanate as an adsorption function material and the paint is obtained by adding nanometer materials such as nanometer titanium dioxide, etc., has the eight times dust collection and dust falling capacities of the prior paint, has the contact angle less than 45 degrees, and the scrubbing resistance more than 4,500 times, meets the requirement of the internal wall paint high-class products, is applied to the surface of the building, and has the functions of dust absorption, dust falling, and easy cleanness besides the function of the inside surface decorative material.

Description

technical field [0001] The invention belongs to the field of building materials and relates to a novel coating material for interior wall decoration. In addition to the basic functions of interior wall decoration and decoration materials, the coating can also effectively remove dust particles in the air, and is easy to clean. It can achieve the purpose of purifying the air by vacuuming and reducing dust. Background technique [0002] The rapid economic development, on the one hand, has greatly improved people's living standards, on the other hand, it has brought huge negative effects on the living environment. The massive discharge of industrial waste, the increasing destruction of environmental vegetation, and frequent human activities all pollute the environment on which people live to varying degrees. One of the important manifestations is the large number of dust particles in the air. According to statistics, in an indoor environment, the number of dust particles larger...
