Description
Technical field
The present invention relates to coating, especially a kind of antistatic coating and preparation method thereof.Be applicable to the covering with paint of electronics, container conduit, upholstery, furniture etc.
Background technology
About the definition of macromolecule conducting material, up to the present still there is not unified standard both at home and abroad.Broadly, generally with volume specific resistance less than 10
10(or surface resistivity is less than 10 for Ω cm
11Macromolecular material general designation macromolecule conducting material Ω) wherein can be divided into polymeric antistatic material (10 again
6～10
10Ω cm), be mainly used in elimination static; Semiconducting Polymer Materials (10
0～10
6Ω cm), be mainly used in heating, electrode, resistance; Macromolecule conducting material (＜10
0Ω cm), be mainly used in conduction, electromagnetic shielding.
From the difference of the raw material that adopts and the difference of manufacture method, macromolecule conducting material can be divided into structure-type (eigenmode) macromolecule conducting material and compound (dosing type) macromolecule conducting material again.The former gets by chemosynthesis, as the polyacetylene that occurs after the seventies, poly-adjoin cough up, Polythiophene, poly quinoline, polyparaphenylene etc.The cost height of present this class electro-conductive material, its practicality wait to expand.The latter is that method is compound makes by blending or lamination etc. with conducting material and macromolecular material, has both had conducting function, has the excellent specific property of macromolecular material again; And cost is lower, good manufacturability, thereby obtained to use widely.Wherein electrically conducting coating is the big classification of one in the conducting polymer composite.
Coating plays the macromolecular material that protection, decoration etc. act on as a kind of article surface that is coated in, and is widely used in the covering with paint of hardware, upholstery, furniture etc.Common coating is because its electrical insulation capability height in use easily produces accumulation of static electricity.Might cause dust suction seriously to be difficult to purify and destruction ultrapurification environment, thereby influence the operation of product appearance or precision instrument; Static discharge can make various precision instruments, electronic devices and components are breakdown and scrap; In industries such as explosive, colliery, oil, chemical industry, weaving, static discharge causes the on fire or blast of inflammable and explosive substances, causes huge serious accident.The Application Areas of antistatic coating is expanded just year by year.
The serious potential safety hazard that causes for the coating accumulation of static electricity, the resistivity that each state all resists static coating all has strict regulation.The surface resistivity of China's standard GB 15599 regulation tank inner wall coatings is not more than 10
9Ω, volume specific resistance is not more than 10
8Ω cm.GB/T 16906-1997 has also made detailed regulation to the measuring method of Oil Tank static conductive coating resistivity.Along with various standards, standard formulation, the production of antistatic coating moves to maturity gradually, and performance also improves gradually.This has expanded the Application Areas of antistatic coating greatly.
Dosing the conductive filler material that uses in the type antistatic coating comprises: metal system, charcoal system, burning system.The ratio of metal system and burning system conductive filler material is great, easily sinks to the bottom caking during heavy addition, is not easy to construction.Charcoal system adopts superfine graphite, super-normal structure black etc., and existing related application or application can be satisfied the anti-electrostatic requirement, and be little to the influence of coating physicals.
Summary of the invention
At above-mentioned present situation, the purpose of this invention is to provide a kind of antistatic coating and preparation method thereof, be intended to make antistatic coating by the biomass charcoal that adds high conductivity, make its antistatic property and anti-static plastic suitable, antistatic property is permanent stable, and the variation with humidity, time does not change; Raw material easily obtains, technology simple, cost is lower and be renewable raw materials.
The technical solution adopted in the present invention is: the main composition of antistatic coating is to be conducting medium with the conductive biomass carbon particle, with the resene tackiness agent is matrix, wherein: the weight percent of biomass charcoal particulate is 2～50, and surplus is resene tackiness agent and solvent.
Described tackiness agent is urethane resin, resol, acrylic resin, Synolac.
In described resene tackiness agent, also can add weight percent and be 0.1～1 carbon black disperser and weight percent and be 0.1～1 coupling agent.
The preparation method of described antistatic coating is: the raw material sources of biomass charcoal is in all kinds of timber, bamboo and other draft class plants, starting material secluding air calcining in 750～1200 ℃ high temperature became biomass charcoal in 5～20 hours, and in powder processing unitss such as ball mill, grind to form the powder particulate that particle diameter is 5～50 μ m, the volume specific resistance that carbon particle is measured after abundant compacting is controlled at 0.1～100 Ω cm, get weight percent and be 2～50 carbon particle, resene tackiness agent with its surplus, solvent phase mixes, and can adopt conventional construction technologies such as spray or brushing.
The percentage composition of described solvent or mixed solvent is 15～50.
Above-mentioned preparation method can add weight percent again when mixing be that 0.1～1 carbon black disperser and weight percent are 0.1～1 coupling agent.
The invention has the beneficial effects as follows: the first, use this coating that body surface is carried out application, consumption is few, and raw material drawing is easy, and preparation cost is low, and its antistatic property and anti-static plastic are suitable; The second, use this coating when increasing the antistatic property of object, not destroy other performance of object inherent (as mechanical mechanics property etc.); The 3rd, permanent the stablizing of antistatic property of using the coating of this coating, the variation with humidity, time does not change; The 4th, use the surface resistivity of this coating to carry out suitable adjusting by the change of filling a prescription as required.
