Abstract

The invention belongs to the technical field of coatings, and particularly relates to a preparation method of stain-resistant real stone paint. The carbon nano tubes and the argil are coated, so thatthe pigment in the color sand is not radiated by light rays; titanium dioxide also has the function of absorbing and converting ultraviolet rays, so that the stone-like paint has good ultraviolet aging resistance; a layer of fluorosilane molecules is formed on the surface of the titanium dioxide nanoparticles in the real stone paint coating; fluorine atoms in fluorosilane molecules of the coatinglayer are high in electronegativity, so that the bond energy of a single bond formed by the fluorosilane molecules and other elements is larger than that of a single bond formed by carbon atoms and other elements, and due to the fact that the carbon chains in the fluorosilane molecules are protected by the original space barrier effect, fluorosilane has good chemical stability and low surface freeenergy. The fluorosilane surface coating layer reduces the Van Der Waals' force of titanium dioxide nanoparticles on water and the effect of hydrogen bonds and greatly increases the contact angle ofthe surface of a paint film, so that the product shows super-hydrophobicity. The preparation method can obviously improve the stain resistance of the real stone paint, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a preparation method of stain-resistant real stone paint. Background technique [0002] In view of the application status and existing problems of exterior wall decoration materials in our country, measures are taken to gradually limit the use of exterior wall decoration materials with high energy consumption, poor safety and environmental pollution, and give priority to the use of high-performance exterior wall coatings. Advocate the application of architectural coatings in decoration projects such as residential buildings, industrial buildings, public buildings and structures. The exterior wall decoration of multi-storey residential buildings, general industrial buildings and public buildings should use architectural coatings with a service life of more than 5 years, and high-rise buildings should have a service life of 5 years. Architectural coatings over 10 years...
