30%;
Lower floor's (adjacent color layers) is main body resin bed, and its thickness is 0.6 ~ 0.8 μm, is made up of high imino group melmac.
The preparation method of described battery label printing carbon ribbon, comprises the steps:
(1) first, it is coated with back coating in base band one side surface, standby after drying;
During coating back coating, by quality ratio, can be in solvent: the ratio of back of the body varnish (back coating material)=8:2, by back coating thing
It is coated after material dissolved dilution, during drying, drying temperature may be designed as 80 ~ 100 DEG C again;
(2) secondly, another side surface of the base band of coating back coating is coated with color layers in step (1), standby after drying;
During coating color layers, by quality ratio, can be in toluene: the ratio of vistanex=4:1, with toluene by polyolefin tree tree
After liposoluble solution, add pigment and auxiliary agent to be ground, be coated again after being ground drying, drying temperature is designed as 80 ~ 100
℃;
(3) the 3rd, in proportion using organic solvent by after Abietyl modified maleic acid resin and aqueous paraffin wax liquor dissolved dilution, apply
Cloth, on the color layers in step (2), makes catalyst layer after drying, standby;Described organic solvent is, for example, specifically second
Alcohol;
During organic solvent dissolving material, by quality ratio, ethanol: (Abietyl modified maleic acid resin+wax liquor)=5:1(is with mass ratio
Meter, Abietyl modified maleic acid resin: wax liquor=5:1), drying temperature is preferably arranged to 90 ~ 100 DEG C;
(4) the 4th, in proportion using organic solvent by after high imino group melmac dissolved dilution, it is uniformly coated on step
(3) catalyst layer surface, is battery label printing carbon ribbon provided herein after drying;
During coating, by quality ratio, organic solvent: high imino group melmac=8:2, described organic solvent is concrete for example
For isopropanol.
One of main innovation point of the present invention is to employ the adhesive layer structure with certain latency reaction solidification,
In this Rotating fields, because so that the waxiness (aqueous paraffin slurry) in catalyst layer is free in catalyst layer the reason preparation temperature
Surface, serves preferably buffer action to Abietyl modified maleic acid resin and high imino group melmac, so that
Can preserve for a long time when battery label printing carbon ribbon is below 50 DEG C;And when specifically used, because when thermal transfer operates, temperature is relatively
Wax can preferably be melted by high (TRANSIENT HIGH TEMPERATURE is up to 180 DEG C), so that Abietyl modified maleic acid resin and high imino group three
Cymel combines and reacts solidification, and then bonds in printing material, thus making it have stronger firmness.
In general, battery label printing carbon ribbon provided by the present invention has high adhesion force, organic solvent-resistant wipes, resistance to
The advantages of high temperature, specifically, through conventional taber instrument wear testing, battery label printing carbon ribbon Rubbing number of the present invention reaches
More than 200 times (existing tradition carbon ribbon is at 50 times about), resistance to alcohol performance reaches more than 100 times, and (existing tradition carbon ribbon is at 50 times
Left and right);Further application experiment shows, battery label is through, in high temperature (110 ~ 150 DEG C) coating process, adhesive layer is again
Solidified, be further ensure that trace is indeformable, not damaged;Simultaneously as battery label provided by the present invention prints carbon
Band its preparation method easy it is easy to popularization and application, thus there is preferably application value.
