Abstract
The invention discloses a kind of steel rust prevention coating, it comprises the component of following massfraction: acrylic resin 20 ~ 35%; Phenylformic acid 25 ~ 40%; Polyamide wax 10 ~ 20%; Modification aluminium triphosphate 15 ~ 20%; Petroleum-sulfonate composite antirust agent 5 ~ 10%.This steel rust prevention coating has low viscosity, high flash point, flame retardant properties and antistatic property.After tested, under the condition that thickness is 45 ± 5 μm, salt spray resistance reaches non-foaming, not corrosion in 650 ~ 690 hours.
Description
Technical field
The present invention relates to rust proof paint, particularly relate to the rust proof paint of steel anti-corrosive, the invention still further relates to the preparation method of this rust proof paint.
Background technology
Most of rust proof paint of the prior art is all water-borne coatings or water-based paint, such as, disclosed in Chinese patent CN1083834, CN1456602A.As its name suggests, water-borne coatings take water as the coating that solvent or dispersion medium are made, and water-borne coatings mainly comprises water soluble paint and water latex paint two class.Its maximum feature is that whole or most of water instead of organic solvent, and filmogen is dispersed or dissolved in water by different way equably, and the rear paint film of dry or solidification has the water-fast of similar solvent based coating and physicals.But the composition of water-borne coatings is much more complicated than coatings volatile organic compounds, and the water volatile ratio solvent evaporates in water-borne coatings needs to absorb more heat, so energy consumption is higher.Therefore, be necessary to prepare a kind of environmentally safe, solvent based coating that energy consumption is low.
And from antirust aspect, the water capacity in water-borne coatings easily causes hardware corrosion, and organic solvent is not easy to form corrosion to hardware on the one hand, also can dissolve some water-fast materials on the other hand.Such as Chinese patent CN1085926A discloses a kind of antirust coatings, and the component that this coating comprises has epoxy system resin and polyvinyl acetal, phosphoric acid, Weibull, phosphoric acid salt, lead salt, ferriferous oxide, talcum powder and organic solvent.Although this coating strengthens toughness and the stability of paint film, the resistance to neutral salt spray performance of coating and corresponding anti-corrosion time are not disclosed.
Summary of the invention
First technical problem to be solved by this invention is the steel rust prevention coating providing a kind of salt spray resistance excellent for the state of the art.
Second technical problem to be solved by this invention is to provide a kind of preparation method of steel rust prevention coating.
The present invention solves the technical scheme that above-mentioned first technical problem adopt: a kind of steel rust prevention coating, comprises the component of following massfraction:
Wherein, steel rust prevention coating also comprises the calcium phosphate that massfraction is 5 ~ 10%.
Wherein, steel rust prevention coating also comprises the zinc sulfide white that massfraction is 5 ~ 10%.
Wherein, steel rust prevention coating is made up of the component of following massfraction:
Wherein, steel rust prevention coating is made up of the component of following massfraction:
Wherein, described petroleum-sulfonate rust-preventive agent comprises petroleum sodium sulfonate, barium mahogany sulfonate and dinonyl naphthalene barium mahogany sulfonate.
The present invention solves the technical scheme that above-mentioned first technical problem adopt: a kind of preparation method of steel rust prevention coating, is characterized in that, comprise the steps:
(1) according to the weight percent of component each in described rust proof paint, the weighing of each component is carried out;
(2) in reaction vessel, first phenylformic acid is loaded, lead to and be steam heated to 80 ~ 85 DEG C, add acrylic resin again, be incubated 1 ~ 2 hour, continue to be warming up to 100 ~ 105 DEG C, be incubated 1.5 ~ 2.5 hours, be cooled to 40 ~ 48 DEG C again, add the agent of petroleum-sulfonate composite antirust and modification aluminium triphosphate and urethane wax, insulation, cooling, obtained rust proof paint.
The present invention solves another technical scheme that above-mentioned first technical problem adopt: a kind of preparation method of steel rust prevention coating, is characterized in that, comprise the steps:
(1) according to the weight percent of component each in described rust proof paint, the weighing of each component is carried out;
(2) in reaction vessel, first phenylformic acid is loaded, lead to and be steam heated to 80 ~ 85 DEG C, add acrylic resin again, be incubated 1 ~ 2 hour, continue to be warming up to 100 ~ 105 DEG C, be incubated 1.5 ~ 2.5 hours, be cooled to 40 ~ 48 DEG C again, add the agent of petroleum-sulfonate composite antirust and modification aluminium triphosphate, urethane wax, calcium phosphate and zinc sulfide white, insulation, cooling, obtained rust proof paint.
Compared with prior art, the invention has the advantages that: this steel rust prevention coating has low viscosity, high flash point, flame retardant properties and antistatic property.After tested, under the condition that thickness is 45 ± 5 μm, salt spray resistance reaches non-foaming, not corrosion in 650 ~ 690 hours.
