Problems solved by technology

On large ships such as aircraft carriers, the method of "exchanging space for protection effect" can be adopted to set up isolation compartments to enhance the protection effect of the hull itself. However, for light ships such as destroyers and frigates, improving the protection performance by improving the existing structure will involve Many complex factors, such as the re-layout of the ship structure, have certain limitations in its application, and at the same time, it seems unable to improve the protection performance of active ships

Embodiment 1

[0037] An anti-underwater explosion impact coating material is composed of A component and B component, and its composition and mass parts are shown in Table 1.

[0038] Table 1

[0039]

[0040]

[0041] A kind of preparation method of anti-underwater explosion impact coating material of the present invention, described method step is as follows:

[0042] (1) Add polytetrahydrofuran ether glycol into reaction kettle Ⅰ with nitrogen protection, heat to 120°C under stirring, dehydrate under vacuum -0.05MPa for 2 hours, remove the vacuum, and add diphenylmethane- 4,4'-diisocyanate, react at 110°C for 2.5 hours, cool down to below 60°C, add propylene carbonate, stir well to obtain component A.

[0043] (2) The amino-terminated polyoxypropylene ether JEFFAMINE T-5000, the amino-terminated polyoxypropylene ether JEFFAMINED-2000, the amino-terminated polyoxypropylene ether JEFFAMINE D-400, the amine chain extender diethyltoluene diamine, and the coupling agent Add Z6040, fil...

Embodiment 2

[0054] The anti-underwater explosion impact coating material and its preparation method described in this embodiment are the same as those in Embodiment 1.

[0055] A kind of application of the anti-underwater explosion impact coating material described in this embodiment: the H-20 / 35 spraying equipment produced by GUSMER is used for spraying construction, and the two components of A and B are separated from the material barrel according to the volume by the respective pumps. The ratio of 1:1 is sent to the host for metering, pressurization, temperature rise, and then sent to the spray gun. The flow of materials in the spray gun is absolutely controlled and free flow is not allowed, so that the materials are mixed in the mixing chamber of the spray gun in the fastest way, and then sprayed on the primer on the surface of the ship hull to form a layer of anti-underwater explosion Impact coating with a thickness of 6mm, then covered with a layer of fiber fabric, and then sprayed ...

Abstract

The invention relates to an underwater explosion shock resistant coating material, a preparation method and an application of the material, and belongs to the technical field of ship protection materials. The material comprises a component A and a component B, wherein the component A comprises 30-65 parts of isocyanate, 30-40 parts of polyether polyol and 0-20 parts of diluents, and the componentB comprises 20-70 parts of amine-terminated polyether, 30-40 parts of amine chain extenders, 0-8 parts of coupling agents, 0-10 parts of fillers and 2-8 parts of auxiliaries. The volume ratio of the component A to the component B is 1:(0.97-1.03). The component A and the component B are prepared, and mixed and then sprayed onto ship shell surface primer by a bi-component high-temperature high-pressure impact mixed airless spraying device to form an underwater explosion shock resistant coating. The dynamic mechanical property of a protection structure under explosive load can be improved by thestrain rate sensitivity of the coating.

Description

technical field [0001] The invention relates to an anti-underwater explosion impact coating material, a preparation method and an application thereof, and belongs to the technical field of ship protection materials. Background technique [0002] At present, the underwater anti-blast and anti-shock capability of my country's active surface ships is only determined by the structural strength of the hull steel plate, and no additional effective anti-shock protection treatment has been carried out. On large ships such as aircraft carriers, the method of "exchanging space for protection effect" can be adopted to set up isolation compartments to enhance the protection effect of the hull itself. However, for light ships such as destroyers and frigates, improving the protection performance by improving the existing structure will involve Many complex factors, such as the re-layout of the ship structure, have certain limitations in its application, and at the same time, it seems powe...
