Abstract
The invention discloses an intumescent fire retardant coating. The coating comprises, by mass, 20-25 parts of ammonium polyphosphate, 2-3 parts of ammonium triphosphate, 3-5 parts of pentaerythritol, 1-2 parts of wollastonite in powder, 5-7 parts of cyano-guanidine, 1-2 parts of diatomite and 10-15 parts of toluene. The coating adopts a reasonable formula, has a low production cost, can prevent flame from spreading effectively once a fire disaster happens so as to protect combustible base materials, and has a thermal insulation function.
Description
Technical field
The present invention relates to a kind of coating, be specifically related to a kind of prescription rationally, the expanding fire-proof paint of low production cost.
Background technology
Expanding fire-proof paint can expand under flame or high temperature action when presence of fire, forms insulated foam coating, and thickness can be tens times of former coat-thickness, intercepted the thermogenic action of external heat source to base material effectively, stops incendiary to continue to spread.
Expanding fire-proof paint of the prior art exists prescription complicated, and production cost is higher, and foaming is even inadequately during presence of fire, can not protect base material effectively.
Summary of the invention
Goal of the invention: the present invention provides a kind of prescription reasonable, the expanding fire-proof paint of low production cost in order to solve deficiency of the prior art.
Technical scheme: a kind of expanding fire-proof paint of the present invention comprises the raw material of following mass fraction: ammonium polyphosphate 20-25 part, triphosphoric acid ammonium 2-3 part; Tetramethylolmethane 3-5 part, wollastonite powder 1-2 part, cyanamid dimerization 5-7 part; Zeyssatite 1-2 part, toluene 10-15 part.
Beneficial effect: formulation for coating material of the present invention is reasonable, low production cost, in case when fire takes place then can effectively stop fire spreading, thereby reach the purpose of the flammable base material of protection, have can be heat insulation effect.
