Problems solved by technology

The epoxy coatings in the above-mentioned patents are all formulated with solid petroleum resin, which has the following disadvantages: First, because the solid petroleum resin has no reactive functional groups, it appears in the state of a mixture in the coating and does not participate in the curing reaction, so it is easy to ooze out. Seriously affect the interlayer adhesion
Secondly, since most petroleum resins are aromatic, they are easily yellowed

Abstract

The present invention is one kind of paint composition for ship ballast tank and belongs to the field of paint chemical technology. The paint composition with special liquid petroleum resin modified epoxy resin has excellent performance, including high water tolerance, high corrosion resistance, excellent flexibility, great adhesion force and high leaching resistance. It consists of special liquid petroleum resin 5-30 %, epoxy resin-1 10-40 %, epoxy resin-2 10-40 %, titanium white powder 18-30 %, talcum powder 10-40 %, antisagging agent 0.5-1.5 %, anti-setting agent 0.5-2 %, xylene 2-10 %, and curing agent 15-39 %, where, the special liquid petroleum resin is liquid petroleum resin with hydroxyl group content as high as 1.0-10.0.

Description

【Technical field】 [0001] The invention relates to an anti-corrosion coating obtained by modifying epoxy resin with special liquid petroleum resin, in particular to a coating composition for ballast tanks of ships traveling at sea, and belongs to the coating chemical industry. 【Background technique】 [0002] In the development of my country's reform and opening up for nearly 30 years, my country's shipbuilding industry and maritime transportation industry have leapt to the forefront of the world. Cargo ships traveling on the sea bear the heavy responsibility of transporting container goods by sea. The sea ships responsible for freight have the process of carrying goods for a long time, and also have short periods of empty load. The lower part of the hull is a semi-spindle-shaped hull, which requires certain stability and "waterline" when submerged in seawater, and the ballast tank at the bottom of the hull is responsible for maintaining the stability of the hull and the water...
