Description
Technical field
The present invention relates to paint field, a kind of aqueous polyurethane anti-flaming dope and preparation method are disclosed.
Background technique
Fireproof flame-retardant coating is coated on flammable substrates surface, can reduce by the combustibility of painting material surface, block fire
Rapid sprawling, or be coated on structural material surface, for improving the fire endurance of component；Fireproof coating generally by base-material,
Decentralized medium, fire retardant, filler, auxiliary agent (plasticizer, stabilizer, waterproofing agent, anti-blushing agent etc.) composition, have been widely used in and have built
It builds, the vehicles such as vehicle, aircraft, tire, historical relic's protection, electric appliance, cable, warehouse, military project, word boat etc..
Anti-flaming dope is generally divided into two class of intumescent and non-expansion type according to fire-retardant principle, and Non-expansive fireproof paint is to lean on
Its own high fire retardant or noninflammability achievees the purpose that fire-retardant fireproof, and the flameproof effect to reach must apply very thick,
Addition largely containing fire retardants such as halogen, nitrogen, phosphorus, generates a large amount of toxic gases, expanding fire-proof paint is exactly film expanded by heating
Honeycomb charring layer is formed, flame heat regulating is isolated and reduces or slow down the transmitting to ground, while coating at high temperature
