The invention discloses an inflaming retarding
coating. The inflaming retarding
coating comprises a component (1), namely an
isocyanate pre-
polymer, a component B (2), namely a
fire retardant which comprises inflaming retarding polyether selected from
acrylonitrile modified polyether and organic
nitrogen compound modified polyether, and a component (3), namely a chain
extender containing an amino. The inflaming retarding
coating provided by the invention does not contain
halogen elements, is high in
solid content, low in
moisture sensitivity and small in
viscosity, needs a small quantity of diluting agent, causes small environmental
pollution and has an environment-friendly effect; the inflaming retarding effect is prominent, and the
adhesive force and the anti-fatigue performance are good; the migration and separation of the
fire retardant are greatly relieved. More importantly, the coating provided by the invention does not lower the mechanical performance and the elasticity of a base material (such as a rubber element) and has low
smoke and low
toxin.
