preparation example Construction

[0052] With regard to the preparation of the intumescent flame retardant of the present invention, it can be achieved by known means, for example simply mixing the four components. Or it can be prepared by first mixing carbon source and acid source into a composition (for example, commercially available VISIL) and gas source and antioxidant to form a composition, and then mixing the two compositions.

[0053] Flame retardant polymer composition and its preparation

[0054] The flame retardant polymer composition of the present invention comprises:

[0055] As the aforementioned flame retardant of the present invention; and

[0056] A polymer precursor that forms a polymer material when cured by heat.

[0057] Preferably, the polymer precursor includes an epoxy resin containing 1,4-butanediol diglycidyl ether and a cycloaliphatic amine-modified hardener.

[0058] Preferably, the polymer material contains one or more of epoxy resin, nylon, polyolefin, and polycarbonate.

Abstract

The invention relates to an expansive type fire retardant, a flame retardation polymer composition containing the fire retardant and a fiber enhanced polymer-based flame retardation composite material prepared by the flame retardation polymer composition. The expansive type fire retardant comprises a carbon source, an acid source, a gas source and an anti-oxidant which contains dis(octadecyl)pentaerythritol diphosphite and / or hexadecyl pentaerythritol diphosphite. The composite material comprises the flame retardation polymeric material body and the continuous fiber positioned in the flame retardation polymeric material body, the flame retardation polymeric material body and the continuous fiber are integrated, the flame retardation polymeric material body can be obtained by solidifying the flame retardation polymer composition containing the fire retardant, and the prepared fiber enhanced polymer-based flame retardation composite material has excellent thermodynamics performance after being burned.

Description

technical field [0001] The invention belongs to the field of intumescent flame retardants and fiber-reinforced polymer-based composite materials, and in particular relates to a quaternary intumescent flame retardant, a flame-retardant polymer composition containing the flame retardant, and a compound prepared by using the composition Continuous fiber reinforced polymer based flame retardant composites. Background technique [0002] Fiber-reinforced polymer-based composites are widely used in aviation due to their high specific strength, high specific modulus, strong designability, good fatigue resistance, and ease of large-area integral molding at low temperatures (when the temperature is lower than 100°C). Aerospace, national defense, ships and transportation and other fields have been widely used. Because the matrix material of the polymer matrix composite material - the polymer softens and melts at a temperature higher than the glass transition temperature, and the molec...
