Wear-resisting type paint for dry bulk carrier cargo hold

Abstract

The invention discloses wear-resisting type paint for a dry bulk carrier cargo hold. The wear-resisting paint comprises raw materials of components in percentage by weight as follows: 18%-30% of epoxy resin adopting one of E-54 epoxy resin, E-51 epoxy resin, E-42 epoxy resin and E-20 epoxy resin, 36%-55% of powder filler, 0.2%-5% of an auxiliary adopting one of organobentonite, fumed silica, hydrogenated castor oil or polyamide wax, 0.5%-5% of a tinting pigments adopting one or two of iron oxide red, iron oxide black and titanium dioxide, 10%-20% of solvents adopting one or two of n-butanol, dimethylbenzene and trimethylbenzene as well as 10%-18% of an epoxy curing agent adopting a polyamide curing agent or a phenol-aldehyde amine curing agent. The paint has good mechanical performance, a test result meets and far exceeds GB / T9262 marine cargo hold paint specifications, as a special paint, the wear-resisting type paint can effectively protect steel plates on the bottom layer and side walls of the dry bulk carrier cargo hold for more than five years, the maintenance time of a dry bulk carrier is shortened, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of industrial coatings, in particular to a wear-resistant coating suitable for cargo holds of dry bulk cargo ships. Background technique [0002] A large number of transport ships are used in the process of sea transportation. Dry bulk carrier is one of the ship types. It is a ship used to load unpackaged bulk cargo. It is specially used to transport bulk materials such as coal, sand, grain, fertilizer, cement, and steel. . During the loading, unloading and transportation of the cargo, the hard particles of the cargo will scratch and scratch the coating surface of the cargo compartment, causing some mechanical damage, thereby affecting the protective effect of the paint coating on the cargo compartment surface, and causing the steel plate in the cargo compartment to rust , Corrosion, resulting in shortened service life of the ship. Therefore, the wear resistance of cargo hold coatings plays a very importan...

AI Technical Summary

Problems solved by technology

[0003] At present, in the marine coating market, cargo hold coating products are mainly alkyd, modified epoxy or pure epoxy products, which are better suited for carrying soft cargo such as grains, fertilizers, and cement in bulk. However, hard bulk cargo, such as coal, sand, steel, etc., will seriously damage the coating on the surface of the cargo hold, and if the bottom and side wall steel plates of the cargo hold are corroded, it will seriously affect the normal operation and service life of the dry bulk carrier
