Said pH value regulator is water-soluble amine solvent.
Said aqueous promoter comprises dispersion agent, skimmer and flow agent, and wherein the parts by weight of dispersion agent are that the parts by weight of 0.5-1, said skimmer are that the parts by weight of 0.05-0.3, flow agent are respectively 0.1-1.5.
Said dispersion agent is phosphoric acid ester dispersion agent, dimethylaminoethyl methacrylate or polycarboxylate sodium's dispersion agent.
Said skimmer is at least a in mineral oil defoaming agent, the ZGK 5 defoamer.The preferred siloxanes of said skimmer.
Said flow agent is acrylic acid or the like flow agent, silicone based flow agent or fluorocarbon class flow agent.
The preferred silicone based flow agent of said flow agent.
Said electric charge adjustment agent is the compound of quaternary ammonium salts.
The present invention with aqueous polyurethane emulsion as matrix resin; Add acetylene black and electric charge adjustment agent as static eliminator; Add low-molecular-weight alcohol, water-based system auxiliary agent, silane coupling agent and deionized water simultaneously and mix by a certain percentage, make coating of the present invention through mechanical stirring, sand milling, filtration etc.
It is solvent and do not adopt organic solvent that waterborne conductive coating of the present invention adopts deionized water, in preparation and the use, does not have the evaporable organic solvent, can environment not polluted, and be a kind of environmentally friendly coating.Waterborne conductive coating of the present invention has good adhesive to the vulcanite charging roller; The coating of processing applies on charging roller that dried coating is wear-resisting, anti-stain characteristic is strong and compactness is fine; The printing test life-span is very long; Can not pollute photosensitive drums, on performance, satisfy the requirement of laser printer vulcanite charging roller (PCR).
The present invention can satisfy the requirement of coating electroconductibility through the addition of regulating static eliminator acetylene black and electric charge adjustment agent.
Low-molecular-weight alcohol mixes the water-based paint solvent with the miscible formation of deionized water; But the air-dry speed ratio water in low-molecular-weight alcohol spraying back is slow; Therefore adopt low-molecular-weight alcohol and reduced air-dry speed as mixed solvent is corresponding, reach good coating result thereby can make filming of spraying keep stablizing with deionized water is miscible.
Adopting pH value modulator effect is to regulate the whole acid of masking liquid, makes masking liquid keep neutral, and pH value regulator and solvent are combined together, and help curing of coating effect and coating performance effect.
The silane coupling agent effect has 2 points: 1. let the discrete maintenance of coating each component well dissolve each other before the spraying, then can make after keep in balance state 2. sprayings and the curing to combine between each component closely, keep good physical properties.
Deionized water, low-molecular-weight alcohol, pH regulator agent and aqueous promoter synergy; Let the preceding coating of spraying have suitable viscosity and the good characteristic of dissolving each other; Help spraying operation, spraying back levelling is abundant, makes the respond well zero defect of filming; Coating dry solidification relief coating obtains high compactness, high-wearing feature, and keeps its good, stable conductivity.
