Abstract
The invention discloses a solvent type organosilicon open fire resisting coating. The coating comprises the following components: 45 to 70 percent of pure silicone resin, 15 to 50 percent of mica powder, and 2 to 18 percent of high temperature resisting pigment. The solvent type organosilicon open fire resisting coating is prepared from the components and the method, and has freely regulated gloss from 0 to 100 and hot hardness reaching 7H; as no heavy metal pigment is used, the coating meets the environmental protection requirements of Rohs Instruction; the coating has good oxidation resisting capability and does not give off no smoke and is non-discolored when the coating is burnt by open fire; and simultaneously the coating has good protective, decorative and anticorrosion properties, and obviously reduces the painting cost compared with a conventional coating.
Description
Technical field
The present invention relates to a kind of coating, particularly a kind of solvent-type organosilicon coating.
Background technology
As everyone knows, the outer resistance to high temperature oxidation protection that contact naked light or high temperature position such as is coated with of heating board, oven, high-grade pot realizes by applying the anti-naked light burning of organosilicon coating usually.Traditional organosilicon open fire burning-resistant coating mainly adopts following prescription to form: silicone resin, white (titanium dioxide); Black (graphite, carbon black and other high temperature resistant glass ceramic are black); Green (chromic oxide etc.); Red (cadmium red, red iron oxide etc.); Yellow (cadmium yellow, iron oxide yellow etc.).Be characterized in: but the heat resisting coating Air drying of this resin preparation is particularly useful for the application of main equipment, has avoided the trouble of main equipment baking inconvenience.Its Good Heat-resistance is applicable to the heat resisting coating in 500～800 ℃ of temperature ranges of preparation.
The shortcoming of tradition organosilicon open fire burning-resistant coating is: 1, use cadmium red, heavy metals such as chromoxide green, serious harm environment and HUMAN HEALTH; 2, the coating total thickness reaches 60～80um, and painting cost is higher; 3, products such as the heating board of traditional silicone resin coating application, oven can be emitted the extremely strong taste of a large amount of pungencys when using for the first time, if room ventilated is bad, very easily cause danger.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of solvent type organosilicon open fire burning-resistant coating, does not use heavy metallic pigment, can safeguard environment and HUMAN HEALTH, reduces painting cost, and is safe and reliable.
In order to solve the problems of the technologies described above, a kind of solvent type organosilicon open fire burning-resistant coating of the present invention, the component of described coating comprises: pure silicone resin 45～70%, mica powder 15～50%, high-temperature resisting pigment 2～18%.
As improvement of the technical scheme, the component of described coating also comprises: organobentonite 0.5～1.5%, propylene glycol carbonic ether 5～10%; The component of described coating also comprises: organic polymer dispersion agent 0.1～0.5%, fluorine modified silicone flow agent 0.05～0.5%, aerosil 0.5～1.5%; The component of described coating also comprises: propylene glycol monobutyl ether 5～15%, ethyl acetate 5～10%, dimethylbenzene 5～20%.
As further improvement in the technical proposal, the production method of described coating is as follows:
A. behind the organobentonite and propylene glycol carbonic ether pre-mixing dispersion with described content, add pure silicone resin and mix;
B. add organic polymer dispersion agent, fluorine modified silicone flow agent, aerosil, mica powder and the high-temperature resisting pigment of described content, be ground to fineness 10～15um after mixing;
C. add in the step B gained mixture after propylene glycol monobutyl ether, ethyl acetate, dimethylbenzene being pressed described content pre-mixing, adjusting viscosity is to obtain finished product behind 25～35S.
The invention has the beneficial effects as follows: this solvent type organosilicon open fire burning-resistant coating adopts said components and method to make, and gloss can be adjusted arbitrarily between 0～100, and hot hardness can reach 7H; Do not use heavy metallic pigment, meet the environmental requirement of Rohs instruction; Have good resistance of oxidation, naked light burns the nondiscoloration of not smoldering, and also has good protection, decoration and antiseptic property simultaneously, and painting cost obviously reduces than traditional coating.
