Fire-resistant coating, also known as flame-retardant coatings Hydraulic block

Its main function is an object of fire retardant protective effect, it can be from the following aspects to destruction of the combustion-shaped
Into the conditions, so as to achieve fire retardant protective effect of: (1) the use of expansion and charring formed by charring and foaming agent
Layer to block the heat conduction;
By melt Shuo caprock to cut off the air; (3) to reduce the heating temperature endothermic reaction; ④ use of halogen-containing
The organics to stop the combustion chain reaction; (5) the use of the decomposition of an inert gas to dilute the combustible gas; ⑥
Changed the thermal decomposition reaction process, to prevent the large amount of exothermic complete combustion reactions. Press the coating composition Classified

Intumescent fire retardant coating and non-intumescent two categories. Models of non-intumescent fire retardant coating self-extinguishing resin,
The Lin Suancu and borate flame retardants, antimony trioxide flame retardant preparation, embarrassed flammable paint. Models
Non-intumescent fire retardant coating is made of silicate and refractory filler, with a non-flammable. Intumescent fire retardant coating is a
Flame-retardant coating, the base material the use of water-based resin, melamine-formaldehyde resins and flame retardant resin chloride, poly-P
Acid money the borate into carbon catalyst, polyol charring agent, the trimer wear amines and other nitrogen-containing blowing agents and fiber-reinforced
Agent. To prevent the plastic ignition and prevent the spread of combustion, can be used alone or in combination the above types of flame retardants
, These transimpedance A agent can be dispersed into the plastic internal, can also be added to the coating, then the coating material is applied to the plastic surface
