Desulphurization high-temperature oxydation, to eliminate CaSO3Adverse effect form CaSO4, make full use of CaSO therein4It is filled out as constitution face
The required component of material, the semi-dry desulphurization ash after simultaneous oxidation are filled in the mechanics that carburization zone can be improved in Intumescent Retardant System
Performance and fire protecting performance.Therefore, by metallurgical solid waste --- coating is added as pigments and fillers after peroxidating in semi-dry desulphurization ash can
To be prepared into intumescent high-performance fire-resistant anti-flaming dope, recycling for solid waste resource is realized, promote reducing enterprise cost.
Summary of the invention
It is difficult to the status that big argument synthesization utilizes for metallurgical solid waste semi-dry desulphurization ash, in order to realize semi-dry desulphurization
The value added applications of ash, prepare a kind of intumescent high-performance fire-resistant anti-flaming dope, improve the skill of existing fireproof flame-retardant coating
The production cost of fireproof flame-retardant coating is effectively reduced in art performance.The present invention using acrylic resin, high chlorinated polyethylene resin,
Composite catalyst, foaming-carbon forming agent, dispersing agent, turpentine oil, anti-heavy agent, semi-dry desulphurization ash micro mist prepare intumescent high-performance
Fireproof flame-retardant coating, while calcination temperature, calcination atmosphere, calcination time, mixing speed, mixing time etc. are controlled, with
Phase realizes that the high added value of semi-dry desulphurization ash recycles.
In order to solve the above technical problems, the present invention is achieved by the following technical programs.
The present invention provides a kind of intumescent high-performance fire-resistant anti-flaming dope, coating raw material by weight percentage is as follows:
The acrylic resin is technical pure；The high chlorinated polyethylene resin is technical pure；The composite catalyst is
The mixture of boric acid, guanylurea phosphate and ammonium polyphosphate, mass ratio 1:1:1~1 of boric acid, guanylurea phosphate and ammonium polyphosphate:

Promote calcium sulfite to be changed into calcium sulfate and forms oxidation sweetening ash micro mist.Utilize CaSO in oxidation sweetening ash micro mist4Replace carbonic acid
Calcium, talcum powder are as constitution pigments and fillers.
(2) due to ammonium polyphosphate can too fast curing acrylic resin and high chlorinated polyethylene resin, using boric acid with
Guanylurea phosphate substitutes part ammonium polyphosphate and is formed using boric acid, guanylurea phosphate and ammonium polyphosphate as the composite catalyzing of primary raw material
Agent, one side boric acid and guanylurea phosphate can alleviate ammonium polyphosphate to the too fast of acrylic resin and high chlorinated polyethylene resin
Solidification；Another aspect boric acid can float on film coated surface, quickly formed and caused during film is thermally decomposed into charcoal foaming and intumescing
Close barrier layer, prevents heat transfer and gas exchanges, and with other components synergistic flame-retardant smoke inhibition；Guanylurea phosphate may be used also simultaneously
Effectively to capture the harmful substances such as free formaldehyde in film, the environmental-protecting performance of coating is improved.
(3) intumescent flame retardant mechanism is as follows: melamine is by thermal decomposition C first3H3(NH2)3=NH3+ C releases noninflammability gas
Body NH3, form expanded foamed layer；Secondly composite catalyst reacts with pentaerythrite, and charcoal bone is formed in expanded foamed layer
Frame；Finally the oxidation sweetening ash micro mist after high-temperature calcination enters charcoal skeleton and forms fine and close hard honeycomb into layer of charcoal, prevents
Only expanded foamed layer is broken through by flame.
Compared with prior art, the invention has the following advantages:
