Description
Technical field
The present invention relates to a kind of Antistatic, high-temperature-resandant andant explosion-proof coating, the invention still further relates to the preparation method of this coating.
Background technology
Traditional coating is in long-time dispersion or long-distance transport process, and due to dispersion, rock, electrostatic can be gathered in coating inside, if electrostatic can not be derived in time, runs up to and to a certain degree may cause combustion explosion.Traditional coating only devises high-temperature resistant organic silicon resin and high-temperature resisting pigment, and only has one paint film protection ground.
People devise antistatic coating to overcome electrostatic, as disclosed a kind of antistatic coating in the Chinese invention patent specification sheets of application publication number CN102690582A, described coating comprises: E-12 epoxy resin, vibrin, silicone resin, pigment and static inhibitor.Although also with the addition of static inhibitor in this antistatic coating, have certain effect of deriving electrostatic, if will reach desirable Hangzhoupro electrostatic efficiency, so the addition of static inhibitor can be relatively very large, thus make do not have advantage on cost.In general coating, static inhibitor is all generally with particle form distribution in coating, can not reach the dispersion of molecular level, make its antistatic effect not good.
And general antistatic coating with the addition of high-temperature resistant organic silicon resin and high-temperature resisting pigment, still only have one paint film protection ground.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and provide a kind of antistatic effect good, addition is low, and cost is low, the Antistatic, high-temperature-resandant andant explosion-proof coating that resistance to elevated temperatures is good.
The present invention's adopted technical scheme that solves the problem is: this Antistatic, high-temperature-resandant andant explosion-proof coating, and its special character is: be made up of mixture first and mixture second;
Described mixture first comprises the component of following weight part: nano-level conducting mica powder 6-8 part, nanometer scale ceramics powder 8-10 part, diacetone alcohol 18 parts, 2 parts, static inhibitor;
Described mixture second comprises the component of following weight part: high-temperature resistant organic silicon resin 56-62 part, silane coupling agent 1 part, high temperature resistant inorganic pigment 5 parts.
Present invention also offers the preparation method of this Antistatic, high-temperature-resandant andant explosion-proof coating, its special character is to comprise the following steps:
1) nano-level conducting mica powder and nanometer scale ceramics powder being soaked 2h with diacetone alcohol ensures fully wetting, then adds static inhibitor, then with dispersion machine in speed be 800-1000r/min rotating speed under stir 5min to be uniformly dispersed, make mixture first;
2) high-temperature resistant organic silicon resin and silane coupling agent are stirred 5min under the rotating speed of 1200-1400r/min, then add high temperature resistant inorganic pigment, stir 10min, make mixture second;
3) by mixture first and the mixing of mixture second.
The present invention compared with prior art, has the following advantages and effect: the high thermal resistance of this Antistatic, high-temperature-resandant andant explosion-proof coating paint film is good, and this coating can be widely used in the high-temperature corrosion environments such as thermal power plant, boiler, smelting.
Antistatic, high-temperature-resandant andant explosion-proof coating of the present invention, static inhibitor and nano-level conducting mica powder is added in formula, the conductive network running through whole coating inside is formed by the functional groups of static inhibitor and nano mica particle, effectively can improve the electroconductibility of coating under liquid or solid state, thus the electrostatic energy of coating accumulated inside can be guided to the packaging container of metal of coating, then by packaging container of metal, electrostatic is caused external static conducting device.The amount of the static inhibitor that coating of the present invention adds and nano-level conducting mica powder can not produce obviously impact to paint film quality.
Antistatic, high-temperature-resandant andant explosion-proof coating of the present invention, devise two pipe protections, nanometer scale ceramics powder is with the addition of in formula, nanometer scale ceramics powder melts gradually in high temperature environments and can form the first layer enamel protective layer by emersion coating surface, enamel protective layer can strengthen the physical strength of film, thermostability, dielectric strength and prevent the erosion of liquid, gas, effectively can ensure that paint film can not cross thermal spalling under high temperature (800 DEG C) condition; And the rear second protective layer that formed of the solidification such as high-temperature resistant organic silicon resin, high temperature resistant inorganic pigment in coating of the present invention, twice protect system effectively improves the work-ing life of paint film.
