Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of antifouling anti-flaming dope and its construction method.
Background technique
It is exactly coated on body surface and is formed by the fiery expanded by heating formation thermal insulation layer of coating chance by fireproof flame-retardant coating
Achieve the purpose that fire protection flame retarding.Fireproof flame-retardant coating be used for flammable substrates surface, can reduce by the combustibility of painting material surface,
Block the rapid sprawling of fire；For non-combustible substrate surface, to improve by a kind of extraordinary painting of painting material fire endurance
Material.Fireproof flame-retardant coating be coated in substrate surface, in addition to fire retardation, also have antirust, waterproof, anti-corrosion, it is wear-resisting and
Heat resistance, coating have toughness, coloring, adhesion, easy stemness and certain gloss.
The fire-retardant principle of fireproof flame-retardant coating is as follows: 1. fireproof flame-retardant coating itself has fire retardant or noninflammability, makes to be protected
The substrate of shield not direct contacted with air and postpone substrate ignition；2. fireproof flame-retardant coating is met, fire is heated to decomposite noninflammability
Inert gas, water down the oxygen in the inflammable gas and air decomposited by protection base material heated, inhibit burning；3. fire prevention resistance
Burning coating material heat can generate the free radical for slowing down and terminating combustion chain reaction；4. fireproof flame-retardant coating heat expand, formed every
The oxygen-impermeable expansion carbon-coating of heat, prevents substrate ignition.Fire retardant is the pass that fireproof flame-retardant coating can play the role of fire protection flame retarding
Key component.Fire retardant can absorb a large amount of heat when heated, release free radical and non-flammable gases that capture burning generates, or
Form the very low expansion carburization zone of heat-insulated oxygen barrier and thermal conductivity.Common fire retardant has following several: (1) halogenated flame retardant, such as
Chlorinated paraffin, decabromodiphenyl oxide, tetrabromobisphenol A etc.；(2) phosphorus flame retardant, such as phosphate, phosphite ester, phosphorus-containing polyol；
(3) halogen-phosphorus flame retardant, such as phosphoric acid trichloroacetaldehyde ester and other halogenated organophosphorus esters；(4) inorganic fire retardants, such as hydrogen-oxygen
Change magnesium, aluminium hydroxide, zinc borate, aluminium borate, antimony oxide, zirconium oxide, barium metaborate, zinc oxide, calcium carbonate, inorganic silicic acid
Salt etc.；(5) expansion type flame retardant, it is a fire protection flame retarding system, this system is by dehydrating agent (acid source), carbon forming agent (carbon
Source), foaming agent (heated decomposite non-flammable gases) composition.As fire protection flame retarding safety standard and environmental regulation are more and more tighter
Lattice have the shortcomings that smoke amount is big, halogenated flame retardant of toxicity is gradually replaced halogen-free flame retardants.Due to organic silicon fibre retardant
It is assigning except the excellent flame retardant property of substrate, moreover it is possible to improve other performances (such as processing performance, mechanical performance, heat-resisting of substrate
Performance etc.), ecology is friendly, and the recycling effect of fire proofing is preferable, is able to satisfy strict demand of the people to fire retardant, close several
Year organic silicon fibre retardant and its flame-retarded technology have obtained faster development.Organic silicon flame-retardant technology mainly there are several types of: (1) add
Add silicone powders；(2) macromolecule silicone oil is used in combination with metallic compound；(3) silicon rubber and organo-metallic compound, White Carbon black be simultaneously
With；(4) polysiloxane grafted or siloxanes containing active function groups and monomer copolymerizable, introduce silicon atom in the molecule.It is siliceous fire-retardant
After polymer introduces halogen or P, flame retardant effect is even more ideal, the reason is that halogen, P and Si have flame retardant synergistic effect.Under high temperature,
Halogen or P facilitate the production of charcoal, and Si increases the stability of layer of charcoal；Also, when replacing silane with siloxanes, the resistance of two element of P/Si
Combustion synergistic effect further strengthens.But there are the following problems for current fireproof flame-retardant coating: (1) fireproof flame-retardant coating does not have generally
Standby antifouling self-cleaning effect is not able to satisfy urban construction, required antifouling automatically cleaning and fire-retardant need in city management
It asks；Traditional fireproof flame-retardant coating generally added by flame retardant amount it is very big, and meet that fiery smoke amount is big, generates gas toxicity
Greatly, all harmful to environment and human body.
Therefore, it develops a kind of with antifouling automatically cleaning and more environmentally friendly anti-flaming dope has great importance.
