Problems solved by technology

[0011] Problems in the prior art: (1) Most of the existing explosion-proof polyurea coatings use graphene oxide as a reinforcing material
(2) If the addition of inorganic fillers has not undergone reasonable surface treatment, two fatal defects will be found under microscopic observation, one is uneven dispersion and agglomeration, and the other is that it is not tightly combined with polymers, or even It is a state of micro-separation (with a gap)
This leads to the separation of the inorganic filler and the high molecular polymer during high-speed impact, and the strength decreases rapidly, and the filler will not be able to enhance physical properties and tear resistance.
The method of increasing the hardness of the hard segment through organic modification will lead to excessive hardness of the material, which is not flexible at low temperature and is easy to break

Abstract

The invention relates to a preparation method of explosion-proof bulletproof high-strength special coating. The coating is prepared from a component A and a component B, wherein the component A and the component B are respectively prepared; the component A is a prepolymer generated by reaction of aliphatic isocyanate, polyester polyol and aminated mixed filler fibers (carbon nanotubes and a high-strength carbon fiber material); and the component B is a product generated by reaction of aspartate, amine-terminated polyether, an amine chain extender, a polyurea modified composite reinforcing material and a catalyst. When in use, the component A and the component B are subjected to construction by spraying equipment or brush coating or roller coating according to a ratio of 1: 1. The obtainedcoating is stable in performance, good in tear resistance and very high in tear strength under high-speed impact due to addition of the amination modified carbon nanotubes and the carbon fibers, and the polyurea modified composite reinforced material has super-strong wear resistance and high physical strength and keeps relatively high strength under the condition of high-speed large deformation. The filling material participates in the cross-linking chemical reaction of the paint coating after surface modification, so that the filling material has tight bonding property with the paint coatingand better flexibility is achieved at low temperature.

Description

Technical field: [0001] The technology of this invention patent relates to the following fields: [0002] 1. Coatings and adhesives involving explosion-proof and bullet-proof; [0003] 2. Metal surface heavy anti-corrosion field; [0004] 3. It can be used as thermal insulation coating; [0005] 4. Used as anti-ultraviolet, wear-resistant, high-strength, waterproof and anti-seepage coating. [0006] 5. Used for anti-static coatings with high conductivity requirements. Background technique: [0007] Explosion-proof: The development of the current world situation poses a certain threat to personal safety, and various accidental or deliberate explosion attacks occur from time to time. When the explosive detonates, the overpressure of the surrounding shock wave can reach tens of GPa, so the buildings and objects around the explosion source will be damaged to a certain extent by the shock wave. The most important point is that the damage caused by the shock wave to personal s...
