Abstract
The invention discloses a kind of intumescent flammable substrate surface fireproof coating and preparation method thereof, including 40-50 parts of polyester resin, 25-60 parts of ammonium polyphosphate, 25-60 parts of aluminum trihydrate, 15-25 parts of powdered whiting, 5-20 parts of phosphorus flame retardant, 15-30 parts of silica flour, 5-8 parts of water-reducing agent, 2~8 parts of dispersing agent, 4~15 parts of adhesive and 160-200 parts of water.For aluminum trihydrate (ATH) when encountering high temperature, gas hydrate synthesis vapor can reduce the temperature of initial fire disaster in the study on formula of fireproof paint；Powdered whiting is able to carry out the absorbing and storing of moisture in coating, can form vapor at high temperature, reduces temperature；Ammonium polyphosphate can form carbon-coating on the surface, and it is reacted with coating other compositions, ammonium polyphosphate dehydration after heated forms polyphosphoric acid, the carbonization of polyester resin surface production can be promoted fire-retardant in turn, substrate can be covered by decomposing the phosphorous oxides generated, it influences construction material by oxygen supply, prevents the intensity of a fire from further spreading.
Description
Technical field
The invention belongs to Surface Engineering field, specifically a kind of intumescent flammable substrate surface fireproof coating and preparation side
Method.
Background technique
Currently, fire-fighting fire-proof engineering ever more important, the major accident as caused by building fire is more and more every year, especially
It is electrical equipment use and building in art work be mostly combustible material, can be using anti-therefore after completing construction
Fiery coating is brushed, and existing fireproof coating is broadly divided into intumescent and non-expansion type, and most popular at present is expansion
Type fireproof coating generates expansion in heat combustion process, and thickness is sharply increased to several times even tens times of original coating,
And charring layer is formed, outgoing oxygen, heat are separated, main lethal factor is asphyxia, existing fire prevention in fire
Coating mostly uses greatly ammonium polyphosphate-pentaerythrite-melamine (APP-PER-MEL) type flame-retardant system, this flame-retardant system
Fireproof coating weatherability and water resistance are poor, in use, its fire retardant in the environment or wet environment directly contacted with water
Water-soluble, phenomena such as saltouing easily occurs, causes fireproof coating to fail, and in the actual production process of coating, to these three former materials
Expect necessary ball milling mixing, leads to energy consumption increase and production hour extends, virtually increase production cost, existing water expansion
Fireproof coating charring layer expansion height is low, and preventing fires, the time is short, adhesion property is poor.
Publication number CN106479297A discloses a kind of aeroge Water-borne inflation type refractory coating and preparation method thereof, fire prevention
Coating includes following components by weight: 10-50 parts of lotion, 30-70 parts of expansion type flame retardant, and the first 0.1-10 parts of neutralizer,
1-10 parts of plasticizer, 2-20 parts of fluxing agent, the first 0.1-10 parts of dispersing agent, the first 0.1-10 parts of stabilizer, aeroge slurry 5-
20 parts and 5-60 parts of pigments and fillers；Wherein, the lotion is hud typed organosilicon-modified acrylate emulsion and pure-acrylic emulsion
Mixture, formula preparation process is complicated, and does not have the function of absorbing moisture between coating and substrate.
Publication number CN105038482A discloses a kind of preparation method of super fire resisting Water-borne inflation type refractory coating, this method
It is raw material using acrylonitrile, vinylacetate, acrylic acid-2-ethyl caproite, emulsifier is added, forms pre-emulsion and sulfurous
Sour hydrogen sodium is mixed to form the base-material of fireproof coating, obtains mixture after the agitated dispersions such as some auxiliary agents are added according still further to formula, to
Polyacrylamide is added in it, and stirring, drying, grinding obtain a kind of super fire resisting Water-borne inflation type refractory coating, this method its in tide
Under wet environment, anti-water energy is poor, and internal effective fire retardant compounds are easy to appear decomposition, and the fire-retardant suppression of the combination between flammable substrate
Fuel efficiency fruit is poor.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of intumescent flammable substrate table
Face fireproof coating and preparation method, the absorption that Environmental Water is carried out by the way that coarse whiting is arranged in coating are matched when encountering high temperature
It closes aluminum trihydrate and decomposes generation vapor, carry out the diffusion of heat, meanwhile, ammonium polyphosphate is formed surface by thermal response and separated, into
And extend heat-resistant time.
In order to achieve the above object, the technical solution adopted by the present invention is as follows:
A kind of intumescent flammable substrate surface fireproof coating, including following component by weight: polyester resin 40-50
Part, 25-60 parts of ammonium polyphosphate, 25-60 parts of aluminum trihydrate, 15-25 parts of powdered whiting, 5-20 parts of phosphorus flame retardant, silica flour
15-30 parts, 5-8 parts of water-reducing agent, 2~8 parts of dispersing agent, 4~15 parts of adhesive and 160-200 parts of water.
Specifically, the polyester resin is unsaturated polyester resin, concrete model 7901, S-906, TM302, in 317
Any one.
The phosphorus flame retardant includes any one or more in phosphate, phosphite ester, phosphate and organophosphorated salt
Mixture.
