Problems solved by technology

Most of the coating protective materials used are imported materials, which are expensive and there is no relevant technology in China.
[0003] Most ships, warships, and offshore drilling platforms now use epoxy resin materials. The materials are hard and easy to crack under collision, causing damage to the coating layer, causing the hull and platform to be corroded by sea water, and causing economic losses.

preparation example Construction

[0048]In the preparation method of the above-mentioned protective coating material for ships, warships and offshore drilling platforms, the preparation method of component A comprises the following steps:

[0049] Step 1. Turn on the vacuum system to make the vacuum in the reactor reach -0.09MPa. Open the stirring system of the reactor, open the suction valve at the bottom of the reactor, absorb the polypropylene oxide polyether polyol MN-3050DF and polypropylene oxide ether glycol DL-4000D according to the formula, and start the heating system of the reactor , heating while stirring, so that the temperature of the material is raised to 80 ° C, and the viscosity of the polypropylene oxide polyether polyol and the polypropylene oxide ether glycol is reduced.

[0050] Step 2. Then turn on the vacuum system to make the vacuum degree in the reactor reach -0.09MPa, and then open the suction valve at the bottom of the reactor to absorb the flame retardant and antioxidant according t...

Abstract

The invention discloses a protective coating material for ships, naval vessels and offshore drilling platforms, and a preparation method thereof, and relates to the field of coatings. The protective coating material comprises a component A and a component B. The component A comprises 425-450 parts of hydroxyl-terminated polyether polyol, 180-210 parts of isocyanate, 190 parts of a flame retardantand 45 parts of an antioxidant; and the component B comprises 330-355 parts of hydroxyl-terminated polyether polyol, 120 parts of a curing agent, 130-180 parts of a flame retardant, 1-5 parts of a silane coupling agent, 21-27 parts of an ultraviolet light absorber, 24-34 parts of a multifunctional auxiliary agent and a proper amount of a pigment. The coating has relatively high bonding strength and hardness, also has flexibility, is not easy to crack, and has long-term waterproof, anticorrosive and fireproof effects. The material has the advantages of no change in performance after being soaked in water for a long term, favorable water resistance and fireproof function, and has the oxygen index of 30 or above. And the smoke is non-toxic, so that secondary injury to personnel is avoided.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a protective coating material for ships, warships and offshore drilling platforms and a preparation method. Background technique [0002] At present, the development of domestic ships, ships, and offshore drilling is on the rise. Most of the coating protection materials used are imported materials, which are expensive and have no relevant technology in China. [0003] Most of the ships, warships, and offshore drilling platforms now use epoxy resin materials. The materials are hard and easy to crack under collision, causing damage to the coating layer, causing the hull and platform to be corroded by sea water, and causing economic losses. Therefore, increasing the tensile strength, improving the wear resistance of the coating, and ensuring the material has a certain degree of flexibility are of great significance for the development of this type of material.
