Abstract

The invention provides a compound nanometer paint as well as a preparing method thereof and a used sprayer and relates to the technical field of paints. The problems that a conventional nanometer paint is low in dispersity, poor in use effect and inconvenient to spray are solved. The compound nanometer paint comprises 1-5 wt% of a compound nanometer oxide, 0.01-0.1 wt% of nanometer aluminum powder, 40-60 wt% of an acrylic acid emulsion, 1-5 wt% of a film forming agent, 1-5 wt% of a dispersant, 1-10 wt% of a defoaming agent, 1-10 wt% of a thickener, 1-2 wt% of a flatting agent, 20-40 wt% of a filler and 10-20 wt% of deionized water and other raw materials, is prepared through mixing, dispersing and grinding and is sprayed by the sprayer with an extension rod. The compound nanometer paint is high in anti-aging performance, long in service life and high in dispersing performance. The used sprayer is convenient to use, good in spraying effect and good in lustre and brightness and cannot have sagging phenomena.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a composite nano coating, a preparation method thereof and a spraying machine used for spraying. Background technique [0002] Due to the small size effect, surface effect, quantum size effect and macroscopic tunnel effect of nanoparticles, they present characteristics that conventional materials do not have in terms of magnetism, light, electricity and sensitivity. Therefore, nanoparticles have broad application prospects in magnetic materials, electronic materials, optical materials, sintering of high-density materials, catalysis, sensing, and ceramic toughening. [0003] With the development of science and technology and the improvement of living standards, people pay more and more attention to a healthy and safe lifestyle. Coatings fill all aspects of people's production and life. Existing coatings either contain a large amount of organic solvents, or the selected materials...
