Environment-friendly fluorine-carbon corrosion-prevention coating and preparation method thereof

Abstract

The invention provides environment-friendly fluorine-carbon corrosion-prevention coating. The environment-friendly fluorine-carbon corrosion-prevention coating is prepared from the following components in parts by weight: 80-100 parts of acrylic modified fluorine-carbon resin emulsion, 2-4 parts of an alkynol auxiliary agent, 3-6 parts of graphene oxide powder, 6-10 parts of nano silicon dioxide powder, 10-15 parts of a film forming auxiliary agent, 3-7 parts of a salt mist resisting agent, 6-12 parts of a pigment, 5-15 parts of talcum powder and 50-80 parts of de-ionized water. The product provided by the invention has extremely high adhesive force; the binding force between a coating layer and a matrix is high; in a coating composition, a dense interface transition layer is formed by the coating layer with the help of a metal oxide nano material and graphene powder, so that the comprehensive thermodynamic property of the coating is matched with the matrix; and the coating can be sprayed and molded on any curve surface, any inclined surface and any vertical plane and does not have a sagging phenomenon.

Description

technical field [0001] The invention belongs to the field of water-based coatings, in particular to an environment-friendly fluorocarbon anticorrosion coating and a preparation method thereof. Background technique [0002] Environmental problems are becoming more and more serious in today's world. A large amount of harmful substances are released during the processing and production of coatings, which will cause environmental pollution and damage the health of construction workers. In order to control pollution and protect the health of construction workers, my country has formulated a series of measures to limit the use of high VOC coatings. Therefore, environmentally friendly anti-corrosion coatings have become the focus of coating development. Among many environmentally friendly coatings, water-based coatings are an important direction of development. However, there are still some technical problems in the current water-based coatings, so improving the corrosion resista...
