Problems solved by technology

However, due to the poor dispersion of graphene in the coating, when there are slight cracks or scratches in the coating, its high conductivity will aggravate the electrochemical corrosion rate of the metal surface. Dry at 400°C, and many substrates of marine monitoring devices are not suitable for high-temperature baking, such as some cables, probes with sensors or monitoring modules, etc.

Abstract

The invention discloses a preparation method for a graphene-based coating for an ocean monitoring device and belongs to the field of coatings. The graphene-based coating is prepared from the followingcomponents in parts by weight: 50-70 parts of combined epoxy resin, 20-30 parts of a diluent, 4-10 parts of graphene, 5-8 parts of fumaric acid, 2-4 parts of caster oil, 10-15 parts of talc powder, 4-9 parts of long chain quaternary ammonium salt, 90-120 parts of polyamide resin and 5-8 parts of graphene oxide. The combined epoxy resin is tetraphenol ethane tetraglycidyl ether epoxy resin and bicyclopentadiene dioxide. The graphene-based coating for the ocean monitoring device can enhance weather resistance of the ocean monitoring device, including compactness, antibacterial property, corrosion resistance and the like. The preparation method is easy to operate, and the obtained graphene-based coating is suitable for the surface of the ocean monitoring device and is coated to be cured in anatural condition, so that the using difficulty and the later coating cost are lowered greatly.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a preparation method of graphene-based coatings for marine monitoring devices. Background technique [0002] The ocean accounts for about 71% of the earth's surface area, and it is rich in resources. The sustainable development of marine resources has also become an important guarantee for human survival. In the past 30 years, people have realized the seriousness of the damage to marine ecology in the past. Many coastal countries and regions Different types of marine protected areas have been successively established to carry out marine protection activities. The monitoring of sea water quality is the basis for carrying out various protection measures. Only after understanding the water quality characteristics of different sea areas can we find the key to the problem and implement corresponding measures. When monitoring seawater quality, the marine monitoring devices used, such as floatin...
