Problems solved by technology

[0002] The metal paint surface protection layer on the market today is basically made of acrylic, polyurethane varnish, high temperature baking varnish and UV varnish, etc., which are cured at room temperature. Their hardness is usually only 1H to 3H, so the surface of the metal paint is very easy to be scratched. The hydrophobic angle Usually less than 90 degrees, it is easy to be polluted outdoors, not easy to clean, and has poor yellowing resistance. In a high temperature environment of 400 degrees, the paint surface will be scorched, blistered, and peeled off.

Abstract

The invention discloses a metal paint surface crystal-plated material. The metal paint surface crystal-plated material is prepared from the following components in parts by weight: 35 to 45 parts of organic silicon resin, 0.1 to 0.2 part of amino silane, 53 to 63 parts of an organic solvent, 0.3 to 0.5 part of a fluorine-containing surfactant, 0.2 to 0.3 part of an ultraviolet light absorber, 0.2to 0.3 part of polydimethylsiloxane, 0.001 to 0.005 part of a catalyst and 0.1 to 0.2 part of isocyanate. The metal paint surface crystal-plated material disclosed by the invention is a polymer whichtakes repeated Si-O bonds as a main chain and of which silicon atoms are directly connected with organic groups, high-temperature solidification in a baking room is not required, the metal paint surface crystal-plated material can be solidified into a crystal glass crystal-plated layer which takes SiO2 as a main component just by generating a chemical reaction-crystallization with water in air, and the metal paint surface crystal-plated material is very good in yellowing resistance, hardness, hydrophobicity, acid-base resistance and the like. Meanwhile, the invention provides a preparation method of the metal paint surface crystal-plated material.

Description

technical field [0001] The invention relates to a surface crystal plating material and a preparation method thereof, in particular to a metal paint surface crystal plating material and a preparation method thereof. Background technique [0002] The metal paint surface protection layer on the market today is basically made of acrylic, polyurethane varnish, high temperature baking varnish and UV varnish, etc., which are cured at room temperature.
