Technical field:
The invention belongs to the light industry technical field, more particularly, relate to a kind of fire-resistant anticorrosion paint and preparation method thereof.
Background technology:
High-temperature resistant coating as its name suggests, is exactly can be in a specified time; in the certain temperature section; stand the coating of oxidation corrosion and other dielectric corrosion under the hot environment, can generally divide organosilicon series and inorganic silicon series in the purpose of works better under the hot environment thereby reach the protection coated article.Accordingly, (between 100-1500 ℃) can reach anti-oxidant, corrosion-resistant and anti-thermal shock, can bear certain performance coating such as mechanical load under hot environment, and we are referred to as high-temperature resistant coating.
Being used for resistant to elevated temperatures heat stable resin has tetrafluoroethylene, polyarylsulphone (ether), polyimide, organosilicon etc., and silicone resin is a class that is most widely used in the heat resisting coating.The resistance toheat of coating is not only relevant with resin (base-material) with antiseptic property, simultaneously confidential relation is also arranged with pigment, stopping composition etc., pure silicone resin can use 300 ℃ of short-terms at 200～250 ℃ of life-time service, and heatproof can be up to 700～800 ℃ behind the adding thermotolerance color stuffing.But with the coating that common silicone resin is made, sticking power, shock-resistance, chemically-resistant and physical strength are not good.
Summary of the invention:
The present invention is exactly at the problems referred to above, and a kind of efficient, stable fire-resistant anticorrosion paint and preparation method thereof is provided.
In order to realize above-mentioned purpose of the present invention, proportioning of the present invention is: the A component: wilkinite is 1.0～2.0%, and N-BUTYL ACETATE is 3.0～6.0%; The B component: Resins, epoxy is 6.0～10.0%, and aminoresin is 4.0～6.0%; The C component: silicone resin A is 28.0～32.0%, silicone resin B is 3.0～7.0%, organic inhibitor is 1.0～3.0%, colour carbon black is 1.0～2.0%, and titanium dioxide is 1.0～2.0%, and graphite is black to be 10.0～15.0%, the high temperature iron oxide black is 2.0～6.0%, talcum powder is 10.0～17.0%, and aluminium triphosphate is 3.0～7.0%, and isopropylcarbinol is 3.0～6.0%.
Preparation method of the present invention is:
The preparation of A component: it is complete that organobentonite is diluted to volumetric expansion with N-BUTYL ACETATE;
The preparation of B component: Resins, epoxy is mixed fully with aminoresin;
The preparation of C component: silicone resin, color stuffing, auxiliary agent, solvent are measured in the adding shredder in accordance with regulations, be ground to fineness less than 30 μ m;
A, B are added among the C, continue to grind dispersion 5～10min, filtration, sealing, packing.
Beneficial effect of the present invention:
1. the present invention has good sticking power, impact resistance, chemical resistant properties and physical strength, and the resistance to elevated temperatures of having a mind to;
2. easy construction of the present invention can be widely used in the various high temperature resistant equipment;
Embodiment:
The present invention is to be base-material with the modified organic silicone resin, adding thermostable rustproof color stuffing, auxiliary agent and solvent composition.
Proportioning of the present invention is: the A component: wilkinite is 1.0～2.0%, and N-BUTYL ACETATE is 3.0～6.0%; The B component: Resins, epoxy is 6.0～10.0%, and aminoresin is 4.0～6.0%; The C component: silicone resin A is 28.0～32.0%, silicone resin B is 3.0～7.0%, organic inhibitor is 1.0～3.0%, colour carbon black is 1.0～2.0%, and titanium dioxide is 1.0～2.0%, and graphite is black to be 10.0～15.0%, the high temperature iron oxide black is 2.0～6.0%, talcum powder is 10.0～17.0%, and aluminium triphosphate is 3.0～7.0%, and isopropylcarbinol is 3.0～6.0%.
Graphite is black, high temperature is iron black, talcum powder, aluminium triphosphate be as main filler, and its effect is thermotolerance, the physical strength that improves coating.
Talcum powder, chemical formula are 3MgO4SiO
