Abstract

The invention relates to highly weather-resistant lead-free catalyst alkyd resin finish, which comprises the following compositions with the contents (weight): 55 to 75 percent of alkyd resin, 10 to 20 percent of pigment, 3 to 5 percent of a film forming additive, 3 to 5 percent of a drier, 0.3 to 1.0 percent of an anti-skinning agent, and the balance being a petroleum solvent (based on 100 percent of the total weight). Compared with the prior art, the alkyd resin finish has excellent weather resistance, can be repaired in an on-line mode, more adapts to flow coating of the prior containers, and forms a continuous coating membrane when the finish is coated on the outer surfaces of the containers; and the coating membrane has more excellent weather resistance and more durable color retention, and is more environment-friendly due to the fact that used film forming materials do not contain heavy metals.

Description

technical field [0001] The invention relates to a non-aqueous medium outer paint suitable for the outer surface of a container, in particular to a highly weather-resistant lead-free catalyst alkyd resin top paint. Background technique [0002] At present, the container manufacturing industry is mainly concentrated in China. China has brought together more than 80% of the global container manufacturing activities. As the world's coating industry is accelerating its transfer, my country, as one of the world's largest coating production countries, has taken the lead in container manufacturing along with the development of the container industry. The field of coatings has achieved a leading position. The container is an international means of transportation between the inland and the sea. Therefore, the container coating must not only withstand any harsh climate conditions on the earth, but also adapt to any mode of transportation on the sea and land. It must have the following c...
