Abstract

The invention provides a long-acting anticorrosive weatherproof functional coating and a preparation method thereof. The coating is prepared by taking bisphenol A type epoxy resin as a main base material, dimethylbenzene and n-butyl alcohol as solvents, as well as a nano-titanium based hybrid material (a titanium and organic polymer grafted product) as a main filler, adding pigments and fillers such as a mica powder and a talcum powder as well as assistants such as a defoamer, a plasticizer and a leveling agent at the same time, uniformly mixing by mechanical stirring, and carrying out spray coating by a spray gun. The coating contains organic polymers and nano-inorganic small molecules; all the components have the advantages of excellent compatibility, high corrosion resistance and excellent ageing resistance. According to the long-acting anticorrosive weatherproof functional coating provided by the invention, by introducing the titanium based hybrid material, the crosslinking densityof the coating can be improved, a binding force between the hybrid material and a matrix can be improved, the defects of short corrosion-resisting cycle and low ultraviolet resistance of a traditional organic coating are improved, and the corrosion resisting and weathering resistance of the coating are remarkably improved. The coatings with different types can be prepared by regulating and controlling parameters of a preparation technology according to an application environment.

Description

technical field [0001] The invention belongs to the technical field of preparation of nanometer functional coatings, and in particular relates to a long-acting anti-corrosion and weather-resistant functional coating and a preparation method thereof. Background technique [0002] Equipment will be affected and affected by environmental factors during its service. Especially when it is in a harsh environment of high temperature, high humidity, high salt spray, and strong ultraviolet light, chemical, electrochemical or physical reactions will inevitably occur, causing it to be damaged or invalidated and corroded. According to statistics, the global annual loss due to corrosion is as high as 1.4-2.2 trillion US dollars, and the weight of steel products scrapped due to corrosion is equivalent to 1 / 3 of the steel output; The loss amounted to 2.13 trillion yuan, accounting for 3.34% of GDP that year. Corrosion will not only bring huge losses to the national economy, but catastrop...
