Abstract
The invention belongs to the field of materials and discloses a waterproof core-shell structure flame retardant and application of the flame retardant to preparation of a polyurethane composite. The flame retardant forms a core-shell structure by taking ammonium polyphosphate as a capsule core and taking a copolymer of melamine formaldehyde prepolymer and multiamino polyether as a capsule wall material. Since a shell of the system is hydrophobic resin, water resistance is highly improved as compared with that uncoated flame retardant particles, loss rate of ammonium polyphosphate particles sealed with filter paper reaches 98.0%, loss rate of the prepared waterproof flame retardant particles under the same conditions is lower than 8.50%, and the polyurethane composite prepared from the waterproof core-shell structure flame retardant has good flame retardant effect and can still keep efficient flame retardance under the condition of long-time water soaking.
