Abstract

The invention discloses a powder coating containing modified nanocarbon and a preparation method of the power coating. The powder coating consists of the following raw materials: modified epoxy resin, tetraphenol ethane tetraglycidyl ether epoxy resin, p-hydroxybenzoic acid hydroquinone diglycidyl, modified nanocarbon, crylic acid type leveling agent, film-forming resin, polydimethylsiloxane, benzoin, aluminite powder, acrylic resin, ultra-fine titanium dioxide, diethylenetriamine, resorcinol and dioctyl ester. The powder coating is a green and environmental-friendly coating, has no toxicity, has high-temperature resistance, contains no solvent and has no VOC (Volatile Organic Compounds) emission; and furthermore, the modified nanocarbon is added in the powder coating, so that the compatibility of the modified epoxy resin, the tetraphenol ethane tetraglycidyl ether epoxy resin and the p-hydroxybenzoic acid hydroquinone diglycidyl is enhanced, the surface leveling of the powder coating is improved, the powder coating has the advantage of high gloss retention and the decorative property of the powder coating is enhanced; and the qualified rate of the finished product obtained by preparing is high and the industrial mass production can be realized.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a powder coating containing modified nano-carbon and a preparation method thereof. Background technique [0002] With the continuous and stable growth of my country's economy and the continuous improvement of people's living standards, the powder coating business of metal components is also increasing, especially in industries such as household appliances, instruments and meters, transportation facilities, aluminum profiles, various vehicles, and daily hardware. , powder coating can provide metal with excellent anti-corrosion protection and decorative properties, but due to the unsatisfactory anti-pollution performance of existing coatings used in the above-mentioned fields, various types of dust, dirt and even oil are often attached to the coating; anti-sticking ability It is also not ideal, and the coating formed by the existing powder coating is prone to blistering, cracking, ...
