Problems solved by technology

With the development of high-efficiency damage warhead technology, new challenges have been put forward for the anti-damage performance of oil tanks / oil tanks, such as the development of high-speed kinetic energy penetrators and energetic fragments. Compared with traditional damage elements, the penetration of high-speed kinetic energy , Explosion or burning chemical damage aftereffect greatly increases the damage probability of oil tanks / oil tanks, so the traditional protection measures of oil tanks / oil tanks can no longer meet the protection performance requirements against modern means of damage

Embodiment 1

[0038] An anti-explosion and anti-ballistic coating material is composed of A component and B component, and its composition and mass parts are shown in Table 1.

[0039] Table 1 Composition of A component and B component

[0040]

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

[0042] (1) Add polytetrahydrofuran ether glycol PTMEG 2000 into the reaction kettle I protected by nitrogen, heat to 120°C under stirring, dehydrate under vacuum 0.085MPa for 1.2 hours, remove the vacuum, and add diphenylmethane after cooling down to room temperature -4,4'-diisocyanate, react at 95°C for 3.5 hours, cool down to below 60°C and add propylene carbonate JeffsolTM PC, get A component after stirring evenly.

[0043] (2) Add amino-terminated polyoxypropylene ether JEFFAMINE T-5000, amino-terminated polyoxypropylene ether JEFFAMINED-2000, amino-terminated polyoxypropylene ether JEFFAMINE D...

Abstract

The invention relates to an anti-knock bulletproof coating material and a preparation method and application thereof and belongs to the technical field of protective materials. The anti-knock bulletproof coating material comprises a component A and a component B; the component A comprises 40-80 parts of isocyanate, 20-55 parts of polyether polyol and 0-10 parts of diluent; the component B comprises 50-88 parts of amine-terminated polyether , 25-50 parts of amine chain extender, 0-5 parts of packing and 0-5 parts of additives. The volume ratio of the component A to the component B is 1 to 0.97-1.03. The component A and the component B are prepared respectively, and are mixed and sprayed to the surface of the base body of an oil tank or oil box by a double-component high-temperature high-pressure impact mixing airless spraying equipment so as to form the anti-knock bulletproof coating. The unique strain rate sensitivity of the anti-knock bulletproof coating can improve the dynamic mechanics performance of the oil tank / oil box under explosive load, and anti-knock anti-impact performance can be improved by reducing structural transformation of the oil tank / oil box.

Description

technical field [0001] The invention relates to an anti-explosion and bullet-proof coating material, a preparation method and an application thereof, belonging to the technical field of protective materials. Background technique [0002] The anti-explosion and ballistic measures of traditional oil tanks / oil tanks are composed of rubber-coated fabric layers, nylon isolation layers and self-sealing natural rubber layers, etc., which make the oil tanks / oil tanks have certain protective properties to a certain extent. With the development of high-efficiency damage warhead technology, new challenges have been put forward for the anti-damage performance of oil tanks / oil tanks, such as the development of high-speed kinetic energy penetrators and energetic fragments. Compared with traditional damage elements, the penetration of high-speed kinetic energy The aftereffect of chemical damage caused by explosion or combustion greatly increases the damage probability of oil tanks / oil tank...
