Abstract

The invention discloses an explosion-proof energy-absorbing polyurea elastic coating and a preparation method thereof. The explosion-proof energy-absorbing polyurea elastic coating comprises an ingredient A and an ingredient B. The ingredient A comprises, by weight, 40-80 parts of isocyanate, 15-35 parts of polyether polyol, 0-10 parts of a chain extender and 5-15 parts of a diluent. The ingredient B comprises, by weight, 40-80 parts of amine-terminated polyether, 20-40 parts of an amine chain extender, 0-10 parts of a filler and 0-10 parts of an auxiliary agent. The invention discloses the preparation method of the explosion-proof energy-absorbing polyurea elastic coating. A coating layer obtained by spray-coating of the explosion-proof energy-absorbing polyurea elastic coating has ultrahigh strength and good flexibility, can effectively resist explosive shock wave and fragments and is especially suitable for being used as a weapon equipment composite armour and a protective coating of military facility.

Description

technical field [0001] The invention relates to an elastic coating and a preparation method thereof, in particular to an explosion-proof energy-absorbing polyurea elastic coating and a preparation method thereof. Background technique [0002] Military vehicles such as tanks, armored vehicles, and off-road vehicles are easily penetrated by explosive fragments due to the strong rigidity of the metal materials used, causing serious injuries to personnel inside. In addition, military facilities such as warehouses and fortifications are also easily damaged by the shock wave of explosives, causing greater losses. [0003] Due to its high strength and high toughness, the sprayed polyurea elastic material can absorb energy well without damage. Combined with the composite armor at the bottom of the vehicle, it can effectively resist the damage to the bottom of the vehicle by explosive fragments; after spraying on the surface of military facilities, it will greatly improve the protec...
