Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] The protective coating for the outer hull of a ship and the application method thereof of the present invention comprise a grease-decomposing agent coating 1, a phenylsilane coupling agent coating 2, an acrylic resin coating 3, an aramid staple fiber coating 4 and a polysiloxane coating 5. Grease decomposition agent coating 1 is coated on the outer hull, and the grease decomposition agent coating 1 is first coated on the outer hull to play the function of cleaning the grease on the surface of the outer hull; the phenylsilane coupling agent coating 2 is coated on the On the grease decomposition agent coating 1, the second step is to coat the phenylsilane coupling agent coating 2, which can improve the adhesion and corrosion resistance of the subsequent coating; the acrylic resin is coated on the phenylsilane coupling agent coating 2, The acrylic r...

Abstract

The invention discloses an outer ship hull protective coating. The protective coating comprises a grease decomposer coating, a phenylsilane coupling agent coating, an acrylic resin coating, an aramidshort fiber coating and a polysiloxane coating, wherein an outer ship hull is coated with the grease decomposer coating; the grease decomposer coating is coated with the phenylsilane coupling agent coating; the phenylsilane coupling agent coating is coated with the acrylic resin coating; the acrylic resin coating is coated with the aramid short fiber coating. The protective coating has the advantage that the outer ship hull can be prevented from being eroded by sea water for a long time.

Description

technical field [0001] The invention relates to a protective coating for the outer hull of a ship and an application method thereof, and belongs to the technical field of hull anticorrosion. Background technique [0002] Ships sailing in seawater are extremely vulnerable to corrosion by seawater, causing the outer hull of the ship to be corroded, causing cracks in the outer hull and affecting the normal running of the ship. The current hull protective coating can protect the outer hull of the ship in a short time, but the hull is long If immersed in the sea for a long time, it will still be eroded by sea water, and the protection effect is not good. In order to solve the above-mentioned difficulties, it is necessary to develop a protective coating for the outer hull of a ship that can protect the outer hull of the ship from being eroded by seawater for a long time and its application method. Contents of the invention [0003] It is an object of the present invention to pr...
