Coating with bulletproof and explosion-proof functions

Abstract

The invention discloses a coating with bulletproof and explosion-proof functions. The composition comprises the following raw materials by mass: 30 to 85 parts of polyurethane, 40 to 85 parts of polyurea, 0.3 to 8 parts of conductive polymer, 5 to 15 parts of nano silicon powder, 0.1 to 2.5 parts of compatilizer, 0.1 to 2.5 parts of defoaming agent, 0.1 to 2.5 parts of macromolecular polyamide-amine dendrimer (PAMAM) dispersion mixing agent, 0.1 to 2.5 parts of flatting agent and 0.1 to 1.5 parts of toner. The polyurethane is any one compound or a composition of several selected from polyesterpolyurethane, polyether polyurethane and epoxy polyurethane, preferably 40-80 parts. The impact resistance of the coating is improved by utilizing mesoporous nano silicon oxide, and zinc carboxylate,bismuth carboxylate and the like are accommodated in a nano cavity of the polyamide-amine dendrimer (PAMAM), so that the uniform dispersion and stabilization effects among organic-inorganic element components and among polyester, polyurea macromolecules, other fillers and additives are promoted; therefore, the coating with excellent bulletproof performance, corrosion resistance and conductivity is prepared.

Description

technical field [0001] The invention relates to the related technical field of functional coatings, in particular to a coating with bulletproof and explosion-proof functions. Background technique [0002] Polyurethane and polyurea two-component functional coatings have good adhesion, chemical corrosion resistance, excellent wear resistance and impact resistance, and are widely used in chemical, military, aviation, navigation and other fields. Based on this principle, the US LINE- The super tough protective coating product developed by X Company - LINE-X, the material can be coated on the wall to prevent blasting, bullets only leave holes but not penetrate, and can be coated on the surface of watermelon and eggs without breaking. As we all know, traditional polyurethane and polyurea functional coatings are mixed with polyurethane, polyurea, conductive polymer, compatibilizer, defoamer, dispersant, leveling agent, toner, etc., and can be formulated by proper combination of the...
