Problems solved by technology

[0002] Currently, acrylic resins are commonly used in the market for finishes, but acrylic resins have major deficiencies in weather resistance and stain resistance. The service life of acrylic finishes can be guaranteed for about 5 years. With the continuous deterioration of the environment, Air pollution and man-made pollution are becoming more and more serious, and the acrylic resin overlay basically cannot achieve the function of anti-staining

Abstract

The invention discloses an inorganic overcoat resin which comprises an inorganic nano material having a solid content of 42-46%, wherein the inorganic nano material is synthesized through a sol-gel method process from the following components in parts by weight: 1-30 parts of ethyl orthosilicate, 1-10 parts of methyltrimethoxy silane, 1-50 parts of mixture of silicon dioxide, aluminum oxide, titanium dioxide and zirconium dioxide and 1-50 parts of water-alcohol mixture; the weight ratio of the silicon dioxide, aluminum oxide, titanium dioxide and zirconium dioxide in the mixture thereof is 50:20:20:10; and the water-alcohol weight ratio of the water-alcohol mixture is 65:35. According to the invention, the inorganic overcoat resin is prepared from the pure inorganic nano material, and the service life can be kept at 15 years or above; and the composition adopts a methyl introduction manner, so that the overcoat has hydrophobic / oleophobic properties, thus ensuring that self cleaning of a decorative layer can be realized by rainfall.

Description

technical field [0001] The invention relates to the field of finish paint / resin technology, in particular to an inorganic finish resin and a preparation method thereof. Background technique [0002] Currently, acrylic resins are commonly used in the market for finishes, but acrylic resins have major deficiencies in weather resistance and stain resistance. The service life of acrylic finishes can be guaranteed for about 5 years. With the continuous deterioration of the environment, Air pollution and man-made pollution are becoming more and more serious, and the acrylic resin overlay basically cannot achieve the function of anti-staining. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and to provide an inorganic overlay resin composed of inorganic nano-materials with super long durability and stain resistance and a preparation method thereof. [0004] In order to realize the above-mentioned purpose...
