Description
Technical field
The present invention relates to the preparation method of a kind of coating dedicated biomass antistatic filler, belong to antistatic material preparation neck
Territory.
Background technology
Static discharge is a kind of phenomenon the most common in daily life, and in a dry environment, human body is in contact sometimes
Can feel there is electricity during metal object, the most also can be appreciated that electric spark, here it is static discharge phenomenon, namely ESD phenomenon.Quiet
Discharge of electricity can produce of short duration discharge current and the strongest electric discharge magnetic field, can cause the electronic equipment misoperation of operation, even interior
Portion's components and parts are damaged, and cause equipment loss of function.One of approach reducing electrostatic hazard increases electric-charge-dissipating speed exactly,
Prevent charge buildup, reduce surface resistivity.
Coating major part is the non-conductor of electricity, at present, has metal-doped electrically-conducting paint.Being doping in electrically-conducting paint
Dividing and should have good electric conductivity, the doping component being typically chosen is silver or copper, but silver and copper are precious metal, are prepared as
This is higher.Meanwhile, the oxidative resistance of metallic conduction coating is very poor, uses time length copper powder, argentum powder to be easily formed oxide layer, doping
The electric conductivity of material changes, and makes it become insulator from conductor, thus loses or reduce electric conductivity.Carbon system filler tool
There are superior weatherability and chemical-resistant, low cost, abundance, as consumption is proper, the physical property of coating affected not
Greatly, thus carbon conductive filler is most widely used in anti-static coatings.But have stronger cohesiveness between carbon system particle, he and have
Between the coating matrixs such as machine macromolecule, affinity is weak, is difficult to dispersed in coating and mixing, and the most common carbon system leads
Electricity filler is graphite and carbon black, and they are with non-renewable oil fossil energy as raw material, and the leading of biomass carbon material
The most weak, therefore prepare a kind of efficient biomass carbon antistatic filler and there is splendid application prospect.
Summary of the invention
The technical problem that present invention mainly solves: have stronger cohesiveness between current carbon system antistatic particle, it and have
