The product has favorable film formation,strong impact-resistant ability and high viscosity, has favorable physical performances of fire resistance, acid resistance, alkaline resistance, salt fog resistance, and the like, and can be widely used for large-scale industrial production of steel structure, and the like. The invention also discloses a preparation method of the fireproofing paint.
Description
Technical field
The present invention relates to technical field of coatings, relate in particular to a kind of fireproofing paint for steel structure and preparation method thereof.
Background technology
At present, because structure iron has intensity height, good toughness, easy to make, series of advantages such as speed of application is fast, building cycle is short, so obtain more and more widely application already in modern architecture.But its fire performance is the focus that people are concerned about always, because its fire performance is poor, traditional way is to apply frie retardant coating in the above, and this method is not only simple and convenient, and economic and practical.Can only increase the coat-thickness of coating in order to improve fire resistance, increase the coefficient of expansion, strengthen fire prevention, preservative effect and reduce cost.Coating ubiquity on the domestic market that the physicochemical property instability maybe can only prevent fires can not be simultaneously antiseptic and rustproof; Though the world market coat have fire prevention simultaneously, antiseptic and rustproof performance, high surprising of price is not suitable for the China market development need.In addition, existing frie retardant coating all adopts the additive flame retardant system, and filmogen does not have flame retardant effect, and the additive flame retardant system is because relative molecular mass is little, form and stripping easily to take place after the coating, ooze out and phenomenon such as volatilization, thereby reduced the fire prevention effect of frie retardant coating.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of film forming is good, viscosity is strong, the fireproofing paint for steel structure of fire prevention, Corrosion Protection excellence.
Another technical problem that the present invention solves provides a kind of preparation method who prepares fireproofing paint for steel structure.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of fireproofing paint for steel structure, form by following materials of weight proportions:
The amino modified resin 4-9 of acrylic acid modified resin 15-25 part part Resins, epoxy 7-15 part
Dimethylbenzene 2-5 part titanium dioxide 2-6 part melamine 3-7 part
Clorafin 2-6 part tetramethylolmethane 2-8 part polyphosphoric acid amine 10-25 part
Zinc phosphate 2-4 part antimonous oxide 1-5 part zinc oxide 2-4 part
Sodium hydroxide 2-4 part auxiliary agent 3-8 part.
Optimum weight proportioning of the present invention is:
11 parts of 6.5 parts of Resins, epoxy of 20 parts of amino modified resins of acrylic acid modified resin
5 parts of 4 parts of melamines of 3.5 parts of titanium dioxides of dimethylbenzene
17 parts of 5 parts of polyphosphoric acid amine of 4 parts of tetramethylolmethanes of clorafin
3 parts in 3 parts of zinc oxide of 3 parts of antimonous oxides of zinc phosphate
5 parts of 3 parts of auxiliary agents of sodium hydroxide.
Described auxiliary agent is made up of the following weight proportion raw material:
Dispersion agent 1-2 part flow agent 0.5-1 part defoamer 1-1.5 part
Softening agent 1-2.5 part.
The method for preparing above-mentioned coating is:
1) earlier acrylic acid modified resin and amino modified resin, Resins, epoxy are dropped in the dispersion machine with above-mentioned formula ratio, add dimethylbenzene then and stir, and resin is fully dissolved;
2) add various raw materials in the prescription successively by the prescription order, a kind of raw material of every adding all makes it its stirring fully wetting and homodisperse;
3) treat that last a kind of raw material adds after, redispersion stirred 30 minutes, then finely dispersed mixture stream was gone in the ball mill;
4) material ground in ball mill 6 hours;
5) filter discharging.
Acrylic acid modified resin and amino modified resin, Resins, epoxy have the effect that film forming is good, viscosity is strong, by they are mixed, as solvent, make the paint coatings of allotting charing expanded very high, and charring layer intensity are also very high with dimethylbenzene;
Titanium dioxide has reinforcement, anti-aging, filling effect;
Trimeric cyanamide is as whipping agent, meets can decompose when hot to discharge non-flammable gases, and these non-flammable gases expand coating, form spongy porous foam structure in coating;
Clorafin have low volatility, fire-retardant, electrical insulating property is good, advantage such as inexpensive, can be used as fire retardant;
Tetramethylolmethane can be heated into charcoal separately or under the carbonifying catalyst effect as char-forming agent, is the basic substance that coating at high temperature forms the foam charring layer of nonflammable three-D space structure, the foam charring layer is played the effect of skeleton;
Polyphosphoric acid amine is as carbonifying catalyst, major function is the thermolysis process that promotes and change coating, isolates shielded base material and burning things which may cause a fire disaster, reduces the inflammable substance that thermolysis produces, discharge water vapour simultaneously, stop the generation of the big oxidation of coal reaction of thermal discharge;
Zinc phosphate has good preservative activity;
Antimonous oxide at high temperature can generate antimony chloride with chlorine-containing resins reaction, can stop spreading of flare and reaches the fp effect.Normal and zinc oxide, sodium hydroxide etc. are used in the plastic cement fireproof system as the synergist of bromide fire retardant.
Zinc oxide impels dope viscosity slightly to improve and reduced precipitation, except having tinting strength and opacifying power, is again sanitas and the luminous agent in the coating;
Sodium hydroxide is used in fireproof system as the synergist of bromide fire retardant.
After having adopted technique scheme, the beneficial effect that the present invention obtains is: have after acrylic acid modified resin and amino modified resin, Resins, epoxy are mixed that film forming is good, a strong shock resistance, effect that viscosity is strong, and physicals such as product resistivity against fire, acid resistance, alkali resistance, salt fog resistance is good, can be widely used in large-scale industrial productions such as steel construction.
