Description
Technical field
The present invention relates to technical field of coatings, particularly a kind of Anti-static emulsion paint.
Background technology
Electrostatic is a kind of objectively spontaneous phenomenon, and the mode of generation is multiple, as contact, friction etc.The action of human body self or the contact with other objects, be separated, and the factors such as friction or induction, can produce the electrostatic of several kilovolts of volts even up to ten thousand.Along with improving constantly of people's living standard, the rate of utilization of household electrical appliance increases day by day, because household electrical appliance are by the restriction of putting the many factors such as place, volume, make household electrical appliance that the anti-static device of fine anti-static effect cannot be installed, but contact that is frequent because of people and household electrical appliance, make in household electrical appliance often with electrostatic, electron device in household electrical appliance can puncture by electrostatic inadvertently, cause short circuit or the open circuit of household electrical appliance, not only cause the infringement of household electrical appliance, also very easily cause the electric shock of personnel.
Antistatic coating is divided into addition type and eigenmode two class, and eigenmode antistatic coating technology is still immature, and thus a large amount of antistatic coating used is generally addition type coating at present.Addition type antistatic coating is in non-conductive binder resin, add the function that certain conductive filler material realizes static conductive, only has the volume fraction of conductive filler material to reach certain degree and could form conductive network or path, embody the character of conduction.Conventional conductive filler material has: carbonaceous material (carbon black, graphite etc.), metal-powder (silver powder, copper powder, nickel powder etc.), metal oxide semiconductor (stannic oxide, ferric oxide, zinc oxide), conducting nanoparticles and anti-electrostatic auxiliary agent etc.Wherein metal-powder density is large, and forming conductive path needs larger volume fraction, and top layer is oxidizable, can reduce and even lose electroconductibility, and corrosion-resistant, thus affect other performances of coating, therefore metal-powder is subject to a definite limitation as the application of conductive filler material; Static inhibitor temperature tolerance, water tolerance, oil-proofness, erosion resistance, poor durability, antistatic property is unstable; Early stage antistatic coating generally adopts carbonaceous material as conductive filler material, along with the development of science and technology, engender the novel conductive fillers such as metal oxide semiconductor and nanometer conductive powder, and applied in electrostatic coatings, this kind of material color is shallow, is easy to toning, enrich the colour system of antistatic coating, but addition is large when this kind of material is used alone, and dispersion stabilization is poor, coating and and the performance of coating can be affected.
Patent CN104356888A discloses the Anti-static emulsion paint that a kind of dispersion stabilization is good, coating performance is good, a kind of Anti-static emulsion paint, be made up of the component of following weight parts: conductive titanium dioxide 15 ~ 25 parts, 25 ~ 35 parts, zinc oxide, acrylate and vinyl acetate emulsion 40 ~ 50 parts, filler 3 ~ 7 parts, emulsion paint auxiliary agent 0.3 ~ 1.2 part.Although this emulsion paint has good electrostatic discharge ability, its ageing resistance is poor, and this has had a strong impact on the life-time service of emulsion paint.
