Abstract

The invention discloses a superhydrophobic self-cleaning alkyd protecting paint and belongs to the technical field of chemical industry. A formula comprises a gasoline solution of alkyd resin, cobalt manganese rare earth, iron oxide red, copper stearate, fine silica powder, ultrafine polytetrafluoroethylene wax powder, ethylene glycol monobutyl ether, diatomaceous earth, and sec-butyl acetate. The superhydrophobic self-cleaning alkyd protecting paint provided by the invention can be applied to surfaces of wood structures, steel structures, railway systems, ships, bridges, and various outdoor hardware equipment, is used as a coating for protection, has micro-scale and nano-scale double rough structure so as to have a superhydrophobic self-cleaning function of lotus effect, is used to protect surfaces of objects from erosion by wind and rain, to keep the surfaces bright as new, to have no need of manual cleaning and re-brushing for returning to new for long term, and to save a lot of manpower and material resources, has service life 3 times that of an ordinary alkyd protecting paint, and is indeed a superhydrophobic self-cleaning alkyd protecting paint with long service life and excellent performance.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to an alkyd paint, in particular to a superhydrophobic self-cleaning alkyd protective paint. Background technique [0002] Alkyd protective paint is a kind of corrosion-prone environment that can be used in high temperature, air pollution and seaside high salinity. Protective coatings for structural structures. However, the ordinary alkyd protective paint coating has no hydrophobic and self-cleaning function. It needs manual cleaning and repainting in a short period of time. The service life is not long, which wastes manpower and material resources. [0003] content of the invention [0004] The purpose of the present invention is to provide an alcohol with lotus leaf effect, self-cleaning function, no need for manual cleaning for a long time, repainting and renewing, saving a lot of manpower and material resources, not being eroded by wind and rain, long service life and excellent ...
