Automobil coating network reported, a world first, energy saving heat preservation can be used in the space of high temperature resistant coatings, heat-resistant up to 1800 ℃, paint main pigment composition for inorganic one component, the author analysis, the inorganic one-component paint for metal oxide miscible pigment pigment (MMO), in the world can so high temperature pigment and has the functions such as shielding infrared non MMO pigment.
It is reported that the coating using special solution without peculiar smell. Temperature tolerance range (80-80 ℃), coefficient of thermal conductivity is only 0.03 W/m.K, can effectively inhibit and block infrared radiation and heat conduction, heat insulation inhibition efficiency can reach 90%, inhibits the thermal radiation and heat loss of high temperature object, the low temperature object to be effective for cold and inhibit the cold environment radiant heat and cause losses, also can prevent the condensation of the object. High temperature resistant coating can also do the high temperature resistant adhesive, this kind of paint can be 1800 ℃ or higher temperature resistance, can be used as coating materials such as ceramic, glass, metal, also can be used as adhesive, such as ceramics, glass, metal is widely used in metallurgy, petroleum, gas, aerospace and other industrial fields. Room temperature daub on metal surfaces, such as drying at low temperature or room temperature from dry, and the adhesion of the metal is very good, very hard, not with blades are and strength after high temperature calcination is more significant, and no crack, resistant to high temperature 1800 degrees, can be used in metallic iron, steel, aluminum, ceramic, glass surface, etc.
The performance characteristics and application scope of extract is as follows:
Appearance: gray slurry, sticky.

Minimum recoat interval: 2 hours
Hardness: 8 h.
High temperature resistant coatings, good oil resistance; Acid and alkali resistance.
Zs high temperature resistant coating, coating thickness: according to customer needs, can be arbitrary thickness, but in the process of construction must be one layer of spray or brush, if you need the thickness of the thicker coating, can put the first layer, the thickness can be controlled in 1 mm, then in the low temperature about 70 ℃ or room temperature after thoroughly dry, may continue to apply the second layer construction, in the third and the fourth floor. Only after the thorough drying can be used into the high temperature condition.
Range of application
All steel products as a shop primer, heavy anti-corrosion coating primer, more suitable for high temperature hot blast stove inside and outside wall, chimney and flue, baked road, exhaust pipe, high temperature heat pipe heat, heating furnace, and other metal coating for high temperature resistant anticorrosive equipment.
The inorganic high temperature resistant coatings, inorganic high temperature resistant adhesive, can also do this kind of paint can be 1800 ℃ or higher temperature resistance, can be used as coating materials such as ceramic, glass, metal, also can be used as adhesive, such as ceramics, glass, metal is widely used in metallurgy, petroleum, natural gas drilling, aerospace and other industrial fields.
Widely used in ceramics, metal products. When the paint is water-based coating, the use of room temperature dry molding, drying hardness can reach more than 5 h after forming. On substrate surface should be clean and dry, no oil, dirt, salt and other impurities, the damaged area should be manual cleaning and repairing, when used according to the specific requirements, can be applied to a few centimeters thickness 0.1 mm, after the test: in the high temperature piping, equipment, furnace (inside and outside), the surface of the container, can effectively inhibit thermal radiation and heat loss.
1, coating on the surface of the object that 1100 ℃ with 8 mm, surface temperature can be reduced to less than 100 ℃.
2, both inside and outside the furnace kiln surface only 6 mm thick coating of high temperature heat insulation coating can reduce heat loss more than 30%.
3, coating on the inner wall of the furnace and kiln is better than any material surface level off is smooth and flame infrared reflection function, reduce the heat furnace wall, furnace flame temperature increase.
4, 30 ℃ below zero in the box with 10 mm thick, high temperature resistant heat insulation coating body temperature is not higher than 0 ℃ in 24 hours.
5, the content of chlorine ion coating is zero, still can prevent the air or process of chloride, sulfide into contact with the metal surface, have very good antiseptic effect on metals, and does not lead to welding the weld metal embrittlement.
6, coatings available on the flue, wind, wind deflector, coating has good wear resistance and impact resistance.
7, coating insulation coefficient is high, has good heat insulating effect.
8 no peculiar smell, coating at high temperature, not deformation, don't break down.
High temperature heat insulation coating waterproof, anti-cracking, fire prevention, sound insulation, fire retardant, insulation, wear resistance, acid and alkali resistance, light weight, convenient construction, long service life, etc.
1, insulation, can effectively prevent heat transfer, keep the object inherent temperature and energy, such as heat insulation, heat preservation, cold, frost, etc.
100% 2, adhesion, adhesion, strong cohesive force, can be thoroughly and material bonding, firmly attached to the object surface.
3, scalability, can prevent the base material at different temperatures caused by cold/hot expansion and contraction, has good tensile strength and elasticity.
4, harmfulness, no peculiar smell, does not contain or does not produce harmful substance composition, carcinogenic substances and other harmful polymers, decomposition and by-products.
5, stability, stable chemical performance, does not react with any material that is not affected by acid, alkali and corrosive substances.
6, abrasion resistance, coating ceramic particles close packing, solvent after composite reinforcement, wearability.
The product price
According to heat temperature section, the basic price for each additional baidu rise 10 yuan/kg, if the poor working conditions the corresponding higher prices.
The construction technology
(1) pretreatment: the surface of the base material must use sandblasting, reach Sa2.5 level;
(2) scrubbing with thinner surface;
(3) using dedicated thinner, adjust the viscosity of coating, thinner, using special diluent, dosage of roughly: airless spraying - about 5% (in coating weight gauge); Air spray - about 15-20% (in coating weight gauge); Brush - about 10-15% (in coating weight gauge);
(4) construction method, airless spray, air spray or brush. Note: construction when the substrate temperature must be higher than 3 ℃ above the dew point, but shall not be higher than 60 ℃;
(5) coating curing: shi and put into use after natural curing under normal temperature or room temperature drying 0.5-1.0 hours, then put in 180-200 ℃ oven bake 0.5 hours, remove to cool.
Prospects for development
As aviation, spaceflight, automobile, and the rapid development of the industry such as weapons, in the aerospace, petrochemical, metallurgy, electric power, military system has been widely used, for the chimney flue, high temperature steam pipe, heat exchanger, high temperature furnace, high temperature desulfurization equipment, petroleum and petrochemical cracking equipment, engine parts and exhaust pipe corrosion, so the performance requirements for the use of metal material is higher and higher, need not only in the use of higher temperature and more harsh corrosive environment, but also has the vibration resistance, fatigue resistance, temperature shock resistance and scouring resistance, organic polymer materials has been difficult to meet the use requirement. With the continuous development of industrial technology, the purpose of the high temperature resistant anticorrosive coatings will be gradually expanded.
The author, the high temperature resistant coatings available marks the high-end technology products in our country, especially in the field of high-end inorganic paints and coatings, has made gratifying progress, has led the world. Take this opportunity to high-end inorganic pigment and coating to expand to a wider range of application fields, deeper for the defense industry and civilian industry and other special industry to contribute.
