Description
Technical field
The present invention relates to fire-resistant anticorrosion paint field, more particularly, to a kind of dura mater casting high temperature resistant based on asbestos
Anticorrosive paint and preparation method thereof.
Background technology
With scientific and technological progress, high-temperature resistant coating more and more appears in every field, for example, jet chimney, high temperature furnace,
Engine components and Metal surface anti-corrosion.Current market sales of high-temperature resistant coating substantially divides organosilicate coating and inorganic
Two series of silicate paint, for the fire-resistant anticorrosion paint of organic series mostly using organosilicon as carrier, its maximum temperature is general
No more than 400 degrees Celsius, it will be carbonized or soften more than this temperature, and inorganic serial high-temperature-resistant adhesive can be held
Widely used by least 1000 degrees Celsius of high temperature, shallow layer can play good anti-oxidation corrosion-resistant effect, and thick coating is not
But good anti-oxidation corrosion-resistant effect can be played, heat insulation and preservation effect can also be played.Ceramics, glass, gold can be used as
The coating materials such as category, are widely used in metallurgical furnace, quartz heating-pipe plates white, coal-burning power plant's pulverized coal preparation system anti-impact corrosive wear coating
Many industrial circles such as coating, automobile engine spark plug ceramic coating anti-carbon deposition, pyroceram ink, aerospace.Often
Temperature spraying is in the body surfaces such as glass, ceramics, metal, low temperature drying or normal temperature self-drying, heavily fortified point very good with the adhesive force on surface
Hard wear-resisting damage resistant, does not crack, function admirable.
Asbestos are also known as " asbestos ", refer to high-tensile, high flexible, chemically-resistant and thermal etching, electric insulation and with can
The silicates mineral products for the property spun.It is the general name of natural fibrous silicates mineral matter, including chrysotile,
Amphibole asbestos, actinolite asbestos, antophyllite, amosite, tremolite asbestos etc..Asbestos are by tow groups into and fiber
Beam is formed by growing very much the very thin fiber that can be separated from each other again.Asbestos have extremely fireproof, electrical insulating property and thermal insulation, are weights
Fire prevention, insulation and the thermal insulation material wanted.Be mainly used for machine driving, braking and insulation, fire prevention, heat-insulated, anti-corrosion, sound insulation, absolutely
Edge etc., wherein more it is important that the manufacturing sector such as automobile, chemical industry, electrical equipment, construction industry.Asbestos fibre has good
Heat resistance, heated generally below 300 DEG C 2 it is small when weight loss it is less, if being heated at a temperature of more than 1700 DEG C 2 small
When, the weight loss of chrysotile asbestos fibre is more, other species asbestos fibre weight loss are less.It is easy how a kind of raw material is prepared
, of low cost, preparation process is easy, and has notable high temperature resistant, and corrosion resistant coating is that high-temperature resistant coating industry needs to solve
A problem certainly.
The content of the invention
In order to solve the technical problems such as conventional method, the present invention provides a kind of raw material and is easy to get, of low cost, preparation process letter
