Abstract

The invention discloses a marine-weather-resistant powder coating containing graphene, the marine-weather-resistant powder coating containing the graphene comprises the following components by mass: 60-80 parts of polyester resin; 4-6 parts of Triglycidyl isocyanurate; 0.5-3 parts of the graphene; 0.3-0.6 part of a leveling agent; 3.5-5 parts of a matting agent; 0.1-0.3 part of a catalyst; 1.2-1.7 parts of a pigment, 5-10 parts of titanium dioxide and 0-20 parts of a filler. The high salt fog resistance powder coating with low price is prepared based on the graphene and the polyester resin, compared with traditional epoxy resin anticorrosive powder coatings, marine-weather-resistance of the marine-weather-resistant powder coating significantly is improved, marine weather resistance, corrosion resistance, environmental friendliness and high cost performance can be all taken into account, and the marine-weather-resistant powder coating greatly promotes the technological upgrading of metal anti-corrosion coatings along the sea area.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a graphene-containing marine climate-resistant powder coating and a preparation method thereof. Background technique [0002] Seawater is a natural electrolyte solution with the largest amount and strong corrosiveness in nature. The climate in coastal areas is characterized by high temperature, rainy and strong wind convection, which leads to long-term high salt spray environment for building materials and engineering equipment in the offshore and ocean. Atmospheric salt spray corrosion is extremely serious. Under the comprehensive effect of strong atmospheric corrosion, electrochemical corrosion and airflow erosion, the service life of various metal components is much lower than that of the general inland environment. The use of conventional powder coatings often causes severe corrosion within half a year. , had to use extremely high-priced fluorine coatings, which constituted a ...
