Background technology
Face the future the development trend of " low-carbon (LC) ", and high temperature organosilicon paint industry early has preparation in fact.In recent years, coating industry is devoted to exploitation low stain, high solid or solvent-free (comprising powder, photocuring) coating, water-borne coatings (organosilicon heat-resistant lacquer) always; The anti-soil technology of exploitation low environment risk and antifouling paint; The rust-stabilising pigment of exploitation non-lead, chromium and substitute develop the process for cleanly preparing of titanium dioxide, iron oxide pigment; Positive formulation coating industry process for cleanly preparing judgement criterias etc., to promote the development of coating industry novel process, novel material and new technology.In addition, the new coatings such as the glass energy-saving coating developed in recent years, heat loss through radiation High tailored coating, sunshade thermal insulation coating, high temperature resistant sealing paint, efficient resistance to stained solar heat absorbing coating, also on " low-carbon (LC) " road, new opportunity to develop is brought for coating industry, but in high-temperature resistant coating for comparatively high temps as 600 degree with the weathering resistance of coating, especially erosion resistance, still Shortcomings.
Summary of the invention
The invention provides a kind of preparation method of resistant to elevated temperatures organosilicon coating, the corrosion resistant performance that its obtained coating has still had when 800 degree of temperature.
A preparation method for high-temperature resistant silicone coating, comprises the following steps:
(1) get grafted-organosilicon resin 45-60% by mass parts, auxiliary agent 2%-4% puts in dispersion cylinder and stirs, and stirring velocity is that 400-500 turns/min, stirs 8-12 minute obtained uniform pre-composition;
(2) get heat resistant pigment aluminium powder 35-45% by mass parts adds in the obtained pre-composition of step (1) under whipped state, adjusting rotary speed is that 400-600 turns/min, churning time is 25-50 minute, control dispersion cylinder temperature≤45 DEG C, inspection viscosimetric≤95s, Gu Han Liang≤75%, obtained organosilicon coating.
Wherein said grafted-organosilicon resin is for containing moisture curing organic resin.
The organosilicon coating that the preparation method of high-temperature resistant silicone coating obtains, containing grafted-organosilicon resin 45-58%(weight part), heat resistant pigment aluminium powder 35-45%(weight part), auxiliary agent 2%-4%(weight part).
The preparation method of high-temperature resistant silicone coating of the present invention prepares on production line at existing coating and just can realize, do not need to increase new facility investment, and obtained high-temperature resistant silicone coating can adopt spraying coating process, brush, roll coating process is constructed, 800 degree of high temperature can be stood for a long time, and there is corrosion resistant performance.
