Abstract
The present invention relates to a process for preparing static preventing coating, which belongs to the field of nonmetallic material. The present invention particularly relates to static preventing coating which can be used for packing coating for ammunition surfaces and ammunition and can also be used for the field of construction, warehouses, traffic, etc. Natural scale graphite sieved by a sieve of 160 mu m, concentrated sulphuric acid and potassium dichromate are mixed by the proportion of 1 to (0.3 to 6.0) to (0.08 to 1.1); after being immersed and oxidized in a reaction still at 25 to 80 DEG C for completing a reaction, the natural scale graphite, the concentrated sulphuric acid and the potassium dichromate are deacidified in a centrifugal deacidifying machine, washed to neutrality, dewatered and dried; prepared and produced material is cracked and expanded at the high temperature of 900 to 1200 DEG C for preparing expanded graphite material; the expanded graphite material is mixed with a film forming substance, pigment, an auxiliary agent and a solvent, and is processed by adjusting a color for preparing the static preventing coating. The material of the present invention replaces an ordinary paint product or a coating product in the field of static discharge, and has the advantages of good static preventing performance, good flame retardant performance, strong adhesive force and easy construction.
Description
Technical field:
The invention belongs to field of non-metallic materials, particularly a kind of Antistatic Paint can be used for ammunition surface and ammunition with package coating, also can be used for fields such as building, warehouse, traffic.
Background technology:
Static discharge is in the daily life and common a kind of phenomenon, and in the exsiccant environment, human body can feel to have electricity when the contacting metal object sometimes, also can see electrical spark once in a while, static discharge phenomenon that Here it is, just ESD phenomenon.Because the phase mutual friction between object is easy to generate electrostatic accumulation, static hazard takes place, disturb the works better of robot calculator, precision instrument, also can explosion caused and fire when serious.Static discharge can produce of short duration discharging current and very strong discharge magnetic field.Can cause the electronics flase operation of operation, even inner components and parts are damaged, cause the equipment loss of function.
One of approach that reduces static hazard is exactly to increase electric-charge-dissipating speed to prevent that electric charge from gathering, and surface resistivity is reduced.The coating major part is the poor conductor of electricity, at present, metal-doped electrically conducting coating is arranged.Doping composition in the electrically conducting coating should have good electroconductibility, and the general doping composition of selecting is silver or copper, but silver and copper are noble metal, and preparation cost is higher.Simultaneously, the scale resistance of metallic conduction coating is very poor, has grown copper powder, silver powder duration of service and has easily formed zone of oxidation, and the electroconductibility of dopant changes, and makes it become isolator from conductor, thereby loses or reduced conductivity.
Carbon material is a kind of good conductor, and it is mixed with common coating, can reach both to have made the surface produce electric charge to spread faster and leak, can not cause the purpose of material discharging again.
Graphite can be avoided metal-doped defective as a kind of carbon material.But the adulterated electrically conducting coating of present Graphite Powder 99 has influenced other performance of coating, for example: color and luster of ADHESION OF PAINTS power, coating or the like because the Graphite Powder 99 doping is bigger.
Summary of the invention:
The present invention seeks to solve with 50 order crystalline flake graphites is that the expanded graphite of feedstock production Antistatic Paint poor adhesive force, the surface aesthetic of making are poor, the problem that color and luster is bad.
A kind of Antistatic Paint, it is characterized in that the present invention produces expanded graphite meterial earlier, the manufacture craft of expanded graphite meterial is: will cross the natural flake graphite of 160 μ m sieve and the vitriol oil, potassium bichromate with 1: (0.3-6.0): mixed (0.08--1.1), in the time of 25--80 ℃ in reactor oxide impregnation to react completely the back in centrifugal acid extractor depickling and washing to neutral, in centrifuge, dewater, dry in moisture eliminator in the time of 80--120 ℃, drying time is about 1-2 hour.It is expanded to prepare material Pintsch process in the time of 900-1200 ℃ of producing afterwards, makes expanded graphite meterial.
The expanded graphite meterial of making of above-mentioned technology has a lot of nano apertures, and specific surface area is very big, have good flame, conduction, anticorrosive, inhale characteristics such as ripple.With organic binder matter, pigment, auxiliary agent, solvent, can make Antistatic Paint through toning processing.
With the expanded graphite meterial for preparing, single-component polyurethane varnish, the special-purpose solvent or diluent of single-component polyurethane varnish, single-component polyurethane varnish special-used colour starch with 1: (14--20): (1--5): ratio (10--15) joins in the agitator, in agitator, stir, promptly make the mono-component polyurethane Antistatic Paint.
With the expanded graphite meterial for preparing, bi-component acrylic/polyurethane lacquer, the special-purpose solvent or diluent of bi-component acrylic/polyurethane lacquer, bi-component acrylic/polyurethane lacquer special-used colour starch, bi-component acrylic/polyurethane lacquer special curing agent with 1: (14--20): (0.1--2): (10--17): 3.0 ratio joins in the agitator, in agitator, stir, promptly make bi-component acrylic/polyurethane antistatic coating.
With the expanded graphite meterial for preparing, single component acrylic varnish, the special-purpose solvent or diluent of single component acrylic varnish, single component acrylic varnish special-used colour starch with 1: (30--40): (5--10): ratio (25--30) joins in the agitator, in agitator, stir, promptly make single component vinylformic acid Antistatic Paint.
With the expanded graphite meterial for preparing, alkyd varnish, the special-purpose solvent or diluent of alkyd varnish, alkyd varnish special-used colour starch with 1: (15--25): (10--15): ratio (10--17) joins in the agitator, in agitator, stir, promptly make the alkyd Antistatic Paint.
Material of the present invention replaces the product of common paint or coating in the static discharge field, good anti-static performance and good flame performance are arranged, and very strong sticking power is arranged and be easy to construction.

Novel electrostatic prevention coating is through the test of national authority electrostatic test mechanism, and surface resistivity is equal to or greater than 10
5Ω/sq, and less than 10
12Ω/sq meets the anti-electrostatic requirement.And because through modification, the usage quantity of carbon material has seldom kept the good smooth finish of coating surface.And ADHESION OF PAINTS power is uninfluenced, and the carbon material after the modification has the structure of nanotube, has good nano-meter characteristic, and more common coating time of drying of Antistatic Paint is shortened dramatically, and has reduced the engineering time, can save the building time.
Through water tolerance, volatility resistance solvent, resistance to acids and bases, weathering resistance experiment, the more common coating of novel electrostatic prevention coating is good.Because the carbon material that uses is anti-fire-retardant material more than 1000 ℃, the flash-point of this novel electrostatic prevention coating is very high, has the good flame performance.
