Problems solved by technology

However, the stability of the superhydrophobic surface obtained by this method is poor, and it is easy to lose hydrophobicity when it is heated and applied outdoors, and there are also some deficiencies in the crack resistance and damage resistance of the coating, so it is difficult to apply it directly. In the field of bronze sculpture surface anticorrosion treatment

Embodiment Construction

[0015] A kind of superhydrophobic anticorrosion paint of low temperature resistance and antifreeze bronze sculpture, is prepared from the component raw material of following weight (kg):

[0016] EP-44 water-based epoxy resin emulsion 40, carboxylated styrene-butadiene latex 3, benzotriazole 0.1, mesoporous silica hollow sphere 3, methyltrimethoxysilane 2, silane coupling agent KH-560 0.5, iso Propanol 6, sucrose fatty acid ester 0.1, epoxy octyl stearate 0.5, nano magnesium hydroxide 0.5, coconut acid glycol amide 0.1;

[0017] The particle size of the mesoporous silica hollow spheres is 1.0-1.5 μm.

[0018] A method for preparing a low-temperature-resistant and anti-freezing bronze sculpture superhydrophobic anti-corrosion coating, comprising the following steps:

[0019] (1) Disperse mesoporous silica hollow spheres evenly in absolute ethanol at a solid-to-liquid weight ratio of 1:10, then add benzotriazole and stir at room temperature for 12 hours, and obtain a composite ...

Abstract

The invention discloses a low-temperature-resistant anti-freezing bronze sculpture super-hydrophobic anticorrosive coating. The low-temperature-resistant anti-freezing bronze sculpture super-hydrophobic anticorrosive coating is prepared from, by weight, 40-60 parts of EP-44 water-based epoxy resin emulsion, 3-5 parts of carboxylic butadiene-styrene latex, 0.1-0.5 part of benzotriazole, 3-5 parts of mesoporous silica hollow spheres, 2-4 parts of methyl trimethoxy silane, 0.5-1 part of silane coupling agent KH-560, 6-8 parts of isopropanol, 0.1-0.2 part of sucrose fatty acid ester, 0.5-1 part of epoxy ethylhexyl stearate, 0.5-1 part of nano-magnesium hydroxide and 0.1-0.15 part of coconut oil ethanediol amide. A super-hydrophobic coating can be formed on the surface of a bronze base through the anticorrosive coating, has the advantages of being excellent in anticorrosive performance, good in coating stability and durable in hydrophobic effect, has good low-temperature-resistant anti-freezing performance, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of anticorrosion of bronze sculptures, in particular to a superhydrophobic anticorrosion coating for low temperature and antifreeze bronze sculptures and a preparation method thereof. Background technique [0002] Sculpture is an important part of Chinese culture, and bronze sculpture is one of the most important forms of sculpture, with extremely high artistic value. Bronze is an alloy with high hardness, good plasticity, bright color and good wear resistance. However, when exposed to the atmosphere for a long time or in the case of high air humidity for a long time, various rust layers will be formed on the surface of the bronze, and even under certain conditions, it will continue to corrode to the deep layer until it festers and perforates, affecting the quality of bronze products and even life. Therefore, in order to ensure the appearance and service life of bronze sculptures, it is necessary to carry ...
