Abstract

The invention discloses a high-flame-retardancy polyurethane composite material. The high-flame-retardancy polyurethane composite material is prepared from hydroxyl-terminated polybutadiene, 4,4'-diphenyl-methane-diisocyanate, toluene diisocynate, epoxy resin, acrylic resin, pentaerythritol triallyl ether, anilmomethyl triethoxy silane, 1,4-butanediol, dibromoneopentyl glycol, dibutyltin dilaurate, dimethythiotoluene diamine, nano-silica, white carbon black, iron-doped nano titanium dioxide, expanded vermiculite, epoxidized natural rubber and a flame retardant, wherein the flame retardant is prepared from expandable graphite, zinc stannate, tri(2-chloroethyl)phosphate, di(4-aminobenzene)phenyl phosphine oxide, tri(2,4-di-tert-butylphenyl)phosphite, aluminum hydroxide and zinc borate. The high-flame-retardancy polyurethane composite material has high intensity and excellent flame retardancy, and can meet use requirements in various fields.

Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a highly flame-retardant polyurethane composite material. Background technique [0002] Polyurethane is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. It has excellent properties such as wear resistance, oil resistance, tear resistance, and chemical corrosion resistance. It has a wide range of uses and can replace rubber, plastic, and nylon. etc., used in airports, hotels, building materials, automobile factories, coal mines, cement factories, high-end apartments, villas, landscaping, colored stone art, parks and other fields. However, ordinary polyurethane materials are extremely flammable, and there are great fire safety hazards in the application process, which greatly limits the practical application of polyurethane materials. Contents of the invention [0003] Based on the technical problems in the background techn...
