Abstract

The invention provides a preparation method for a surface hydrophobic and oleophobic film of a bronze drum, and belongs to the technical field of anticorrosion of metalware. The method comprises the following steps that (1) the newly cast bronze drum is cleaned up through a cleanser solution to remove grease and pollutants covering the surface, and then the surface of the bronze drum is repeatedly purged with clean water; (2) the purged bronze drum is soaked in a polyhydric alcohol ethanol solution, and ultrasonic equipment is used for conducting ultrasonic treatment on the bronze drum; (3) a perfluoro fatty acid organic solution is prepared; and (4) the bronze drum subjected to the ultrasonic treatment is placed in the perfluoro fatty acid organic solution to be soaked, so that the coating film is formed on the surface of the bronze drum. Through the simple and effective two-step solution self-assembling grow method, the method for obtaining the hydrophobic and oleophobic film on the surface of the bronze drum is provided, the surface of the bronze drum has the oil pollution resistance and self-cleaning functions, the corrosion resistance of the surface of the bronze drum is improved, and the water discharging, oil discharging and self-cleaning properties of the surface of the bronze drum are improved.

Description

[0001] 【Technical field】

[0002] The invention relates to the technical field of anticorrosion of metal products, in particular to a method for preparing a hydrophobic and oil-repellent film on the surface of a copper drum.

[0003] 【Background technique】

[0004] The Bronze Age was the first era in which humans utilized metals, and archaeologically marked an important stage in the development of human culture. Bronze ware has extremely high historical value, artistic value and scientific value. However, due to the fact that the bronze material itself is prone to corrosion in humid air, and the ancient bronzes have experienced thousands of years of long years, and the environment they are in is complex and diverse, these precious cultural relics have suffered irreversible damage. Therefore, establishing an effective protection method is a demand and a common problem faced by the protection of precious bronze cultural relics in the museum.

[0005] In recent years, the constr...
