Abstract
The invention discloses a silicone resin heatproof paint, which is mainly composed of silicone resin and is prepared by adding a coloring pigment, a body pigment, an anti-settling agent, and a curing agent into the silicone resin. The silicon resin heatproof paint has the characteristics of high heat resistance temperature, good anticorrosion performance, strong adhesive force, and resistance to acid, alkali, and gasoline; and can be applied to heatproof and corrosion-resistant coating of high temperature heat engines or products such as heat exchanger, engine shell, heating equipment, articles for daily use, and the like.
Description
The present invention belongs to heat-resisting, the anti-corrosion coating of a kind of specific function of chemical field.
Existing silicon resin, heat-resistant paint, has good thermotolerance and solidity to corrosion must adopt lower painting and the two-layer different coating of upper painting.The heat resisting coating for thermo-mechanical equipment that Japan's " Industrial materials " the 23rd volume o.11 magazine is reported to, the P20 heat resisting coating that lower painting adopts, upper painting adopts M-18-K heat resisting coating, but does not see the detailed composition of coating in document.In two coatings, lower painting mainly plays preservative activity, and upper painting mainly plays high temperature resistant effect, is 35-40 μ at the thickness of substrate surface two coating of coated article.But take Secondary coating process, cause coating process complexity, coating consumption many, thus painting cost is high.
In order to overcome the shortcoming of existing heat resisting coating, provide a kind of be coated with one deck can meet high temperature under the good coating of the physical property such as heat-resisting, anti-corrosion, be object of the present invention.
Silicon resin, heat-resistant paint provided by the present invention is made up of neat silicone, sex change epoxy silicone, tinting pigment, pigment extender, glass powder, zinc powder, anti-settling agent, solidifying agent, solvent materials.According to the coating specification of coated article, black, white, the red, yellow, and green look pigment (see table 1) with heat-resisting function can be selected.Pigment extender can adopt kaolin, talcum powder, barium sulfate, mica powder, calcium carbonate, aluminium powder etc.Anti-settling agent adopts bentonite.Solidifying agent adopts naphthenate or the zincate of iron, cobalt, manganese.Solvent adopts the organic solvents such as toluene, dimethylbenzene, alcohols, ketone, ester class, glycols.The present invention adopts above-mentioned raw materials to make the proportioning of coating in the proportioning of table 2. by raw material described in table 2, can be made into the heat resisting coating required by 200 DEG C of-600 DEG C of differing tempss.
Heat resisting coating of the present invention, adds the organic solvent of 10-15% again before using, after making coating be diluted to certain viscosity, and the substrate surface spray gun spraying of thing in transit or the rete of electrostatic spraying one deck 20-40 μ, and then dry 20-30 minute at 180 DEG C of temperature.The metallic surface of coated article, preferably carries out diamond spar inject process before spraying.So not only can reach the object of derusting of metallic surface, and the roughness of metallic surface can be increased, to improve the sticking power of heat resisting coating in metallic surface.

Silicon resin, heat-resistant paint provided by the present invention, has that heat resisting temperature high (can reach 600 DEG C), non-corrosibility are good, strong adhesion, and the feature such as acidproof, alkaline-resisting, resistance to gasoline.The present invention is widely used in the heat-proof corrosion-resistant application of the various high temperature services such as vapor pipe, sound damper, stove, heat exchanger, heating facilities, engine case, pot.
One of embodiments of the invention.By the silicon resin, heat-resistant paint described in table 2, adopt Cr

4the black pigment of mixture, physique is talcum powder in the eyes, and solidifying agent adopts manganese naphthenate, and solvent is the mixture of toluene and alcohol.The coating that concrete proportioning makes by table 3 proportioning in table 3., uses and adds 60 grams of same solvents again and fully stir, and on after metal testing plate, that is coated with the thickness of one deck 20-40 μ, then dries 20 minutes at son 180 DEG C of temperature.Test piece after oven dry is constant temperature 5 hours at 200 DEG C, 300 DEG C, 400 DEG C, 500 DEG C, 550 DEG C, 600 DEG C temperature respectively.Test film obtained like this, through physical property measurement, shows that thermotolerance under all temps, solidity to corrosion, petrol-resistance are all good.If add a little smooth agent raw material in coating, then coatingsurface is more smooth.
