Abstract

The invention provides a carbon nanotube modified polyurea explosion-proof material. The preparation method includes: preparing functionalized carbon nanotubes, preparing a polyurea elastomer material, and mixing the functionalized carbon nanotubes with the polyurea elastomer material to obtain the carbon nanotube modified polyurea explosion-proof material. Carbon nanotubes are functionalized in advance, the functionalized carbon nanotubes are connected into polyurea elastomer resin by means of combining conventional physical dispersion with chemical reaction, and the whole process does not contain non-reactive pigment and filler, so that physical reinforcing of filler to the material is abandoned, and the defect that the material is poor in low-temperature flexibility due to the fact thatthe material is reinforced by increasing hard segment content in a resin system is avoided. The carbon nanotube modified polyurea explosion-proof material can be used in military facilities and explosion-proof energy-absorbing protection equipment, has good actual effect and practical value, can resist shock waves and fragments caused by explosion and meets basic requirements of military equipment.

Description

technical field

[0001] The invention relates to the technical field of explosion-proof material compositions, in particular to a carbon nanotube modified polyurea explosion-proof material and a preparation method thereof. Background technique

[0002] Spraying polyurea materials are widely used in the fields of submarine pipeline, buried pipeline anticorrosion, storage tank anticorrosion, concrete protection, waterproof, military skin, chassis protection, etc. because of its solvent-free environmental protection, high mechanical strength, and quick construction. Applying it to the field of military anti-ballistic and explosion-proof protective materials requires that the coating not only have super high physical strength, but also exhibit good tear resistance under high-speed impact, but it is difficult for conventional polyurea products to achieve the above-mentioned Require. The current conventional solution is to add special fillers to the polyurea resin system or use a ...
