Problems solved by technology

[0002] Existing water-based polyurethane resins basically have no flame retardancy. In order to achieve flame retardancy, a large amount of flame retardants must be added, and the addition of a large amount of flame retardants will inevitably affect product performance.
If the amount of flame retardant added is large, the amount of film-forming resin is relatively small, and the fastness is poor; in order to improve the fastness, the amount of resin must be increased, the amount of flame retardant is relatively reduced, and the flame retardancy is reduced

Abstract

The invention discloses flame retardant waterborne polyurethane resin which comprises a component A and a component B. The component A is prepared from the following ingredients in parts by weight: 30-50 parts of diethylene glycol phthalic anhydride polymer, 40-60 parts of polybutylene glycol, 15-30 parts of diphenylmethane diisocyanate, 5-10 parts of chain extender, 2-5 parts of triethylamine, 1-2 parts of dibutyltin dilaurate, and 300-500 part of water. The component B is prepared from the following ingredients in parts by weight: 10-20 parts of melamine polyphosphate, 20-30 parts of piperazine phosphate, 10-20 parts of piperazine pyrophosphate, 10-20 parts of tetraphenyl pyrophosphate, 30-40 parts of halogen alkyl phosphate, and 10-20 parts of bisphenol A phosphate. The weight mixing ratio of the component A to the component B is 1:(0.5-1). The flame retardant waterborne polyurethane resin, disclosed by the invention, is high in flame retardance and high in film-forming property.

technical field [0001] The invention relates to a flame-retardant waterborne polyurethane resin. Background technique [0002] Existing water-based polyurethane resins have basically no flame retardancy. In order to achieve flame retardancy, a large amount of flame retardants must be added, and adding a large amount of flame retardants will inevitably affect product performance. If the amount of flame retardant added is large, the amount of film-forming resin is relatively small, and the fastness is poor; in order to improve the fastness, the amount of resin must be increased, the amount of flame retardant is relatively reduced, and the flame retardancy is reduced. Contents of the invention [0003] The object of the present invention is to provide a flame-retardant water-based polyurethane resin, aiming at solving the above problems. [0004] In order to achieve the above object, the technical solution of the present invention is to design a flame-retardant water-based p...
