Description
Technical field
The present invention relates to paint field, particularly, the present invention relates to a kind of fireproofing flame-resistant protective system.
Background technology
Frie retardant coating is for flammable substrates surface, can reduce by the rapid spread of the combustibility of painting material surface, retardance fire, in order to improve by a kind of speciality coating being coated with material fire endurance.Frie retardant coating is coated in substrate surface, except having fire retardation, also has antirust, waterproof, anticorrosion, wear-resisting, heat-resisting and coating tenacity, tint permanence, adhesion, the easily performance such as dryness and certain gloss.
The fireproofing mechanism of frie retardant coating roughly can be summarized as following 5 points:
(1) frie retardant coating itself has flame retardancy or uninflammability, and protected base material is not directly contacted with air, postpones the speed that object catches fire and reduces burning.
(2) frie retardant coating is except itself having flame retardancy or uninflammability, and it also has lower thermal conductivity, can postpone the transmission of flame temperature to protected base material.
(3) frie retardant coating decomposes goes out and does not fire rare gas element, waters down the inflammable gas that protected object decomposes goes out, and makes it nonflammable or combustionvelocity slows down.
(4) nitrogenous frie retardant coating decomposes goes out NO, NH
3deng group, with organic radical chemical combination, interrupt chain reaction, reduce temperature.
(5) expanding fire-proof paint expanded by heating foaming, forms carbonaceous foam thermofin and closes protected object, postpone the transmission of heat and base material, stops the strength degradation that object ignition or Yin Wendu raise and cause.
Frie retardant coating numerous at present, be no matter solvent-borne type or water-based have a common defects: poor water resistance, and can only indoor scenarios be used in, be rarely used in outdoor, because wet, chance water (snowy and rainy day) paint film meeting bubbling, paint film can be damaged in the course of time, and the life-span is protected in impact, more seriously run into fire alarm, because the inefficacy of resistance fire material of preventing fires in paint film or loss can affect rescue.
The defect of existing frie retardant coating is: poor water resistance, can only be used in indoor scenarios, not fire-resistant, poor adhesive force, anti-intensity difference.Major cause is: fire retardant in formula, to become carbon skeleton agent mostly to have water-soluble and not water-fast.Resin glue is organism, has incendivity and not fire-resistant.Certainly, chlorinated rubber, supervinyi chloride resin, because it contains chlorine atom, have burning difficulty and can extend one section of light-off time, but eventually can burn.And all there is the drawbacks such as poor adhesive force, anti-intensity difference is not enough in above-mentioned base-material.
CN101880486A relates to a kind of epoxy intumescent fire retardant paint and manufacture method, by the lower molecular weight bisphenol A type epoxy resin of polymerization degree < 2, bisphenol f type epoxy resin, saturated polyester resin and ethylene propylene acid esters join dimethylbenzene, propyl carbinol, mibk, in the mixed solvent of solvent oil, add ammonium polyphosphate again, trimeric cyanamide, tetramethylolmethane, antimonous oxide, clorafin, aluminium hydroxide, zinc borate, Rutile type Titanium Dioxide, sericite in powder, benzotriazole phenol, polyacrylic ester interpolymer solution, poly-methyl alkyl siloxane solution, through mixing, stir, epoxy intumescent fire retardant paint A liquid is made in grinding, by polymeric amide, talcum powder, expanded graphite joins dimethylbenzene, in the mixing solutions of propyl carbinol, through mixing, stir, epoxy intumescent fire retardant paint B liquid is made in grinding, by two component mixing during use.But the water tolerance of this coating and poor adhesive force, can not meet the needs of outdoor utility.
Therefore, provide a kind of water-fast, can use in indoor and outdoor, the technical barrier that fire-resistant, sticking power good, the coating of anti-excellent strength is affiliated field.
