Description
Technical field
The present invention relates to a kind of antistatic high temperature resistant explosion-proof coating, the invention still further relates to the preparation method of this coating.
Background technology
Traditional coating long-time disperse or the long-distance transport process in owing to disperseing, rocking, static can be gathered in coating inside, if static can not in time be derived, runs up to a certain degree and may cause combustion explosion.Traditional coating has only designed high-temperature resistant organic silicon resin and high-temperature resisting pigment, and only has paint film protection ground one.
People have designed antistatic coating in order to overcome static, disclose a kind of antistatic coating in the Chinese invention patent specification sheets such as application publication number CN 102690582 A, described coating comprises: E-12 Resins, epoxy, vibrin, silicone resin, pigment and static inhibitor.Although also added static inhibitor in this antistatic coating, have the effect of certain derivation static, if reach desirable Hangzhoupro electrostatic efficiency, the addition of static inhibitor can be relatively very large so, thereby so that do not have advantage at cost.In the general coating, static inhibitor generally all is to distribute with particle form in coating, can not reach the dispersion of molecular level, so that its antistatic effect is not good.
And the interpolation of general antistatic coating 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 the prior art, and provide a kind of antistatic effect good, addition is low, and cost is low, the antistatic high temperature resistant explosion-proof coating that resistance to elevated temperatures is good.
The present invention addresses the above problem the technical scheme that adopts: this antistatic high temperature resistant explosion-proof coating, and its special character is: be comprised 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, 18 parts of diacetone alcohols, 2 parts in static inhibitor;
