Abstract

The invention discloses super-hydrophobic polyester protective paint, and belongs to the technical field of chemical engineering. The super-hydrophobic polyester protective paint is characterized by being composed of a styrene solution of polyester resin, whitewater, methyl ethyl ketone peroxide, a paraffin styrene solution, zinc oxide micropowder, ultrafine Fischer Tropsch wax micropwder, dimethyl ketone, a dispersing agent 904S, calcium carbonate and kaolin. The finished product super-hydrophobic polyester protective paint can be applied to resisting corrosion of steel materials and wood materials, and resisting carbonation of concrete, and can be also applied to surfaces of various kinds of outdoor and indoor ironmongery goods in ships, bridges and the like as the paint for protecting the surfaces. The super-hydrophobic polyester protective paint has both a micro-scale coarse structure and a nano-scale coarse structure, and thus has the super-hydrophobic function with a lotus leaf effect. After the super-hydrophobic polyester protective paint is utilized, the surface of an object does not need to be artificially cleaned and painted repeatedly so that the object can be returned to a new one for a long time, and thus a lot of labor and materials are saved; meanwhile, the super-hydrophobic polyester protective paint is not eroded by wind and rain, and the service life of the super-hydrophobic polyester protective paint is three folds that of common polyester protective paint, and thus the super-hydrophobic polyester protective paint is indeed the paint which is long in service life and excellent in performance.

Description

technical field [0001] The invention belongs to the chemical industry field, and the invention relates to a polyester paint, in particular to a superhydrophobic polyester protective paint. Background technique [0002] Polyester protective paint is a kind of protective coating that can be applied to steel anti-corrosion, wood anti-corrosion, concrete anti-carbonization, ship bottom anti-plankton, deck anti-wear and other structures. However, the polyester protective paint coating has no hydrophobic and self-cleaning function. In the short term, it needs to be manually cleaned and repainted to renew it. 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 a superhydrophobic polyester protective coating with self-cleaning function, no need for manual cleaning for a long time and repainting, saving a lot of manpower and material resources, not being eroded by wi...
