Thermal sublimation and transfer digital paper with high ink suction amount

ActiveCN103397576AIncrease ink absorptionQuick ink absorptionSurface covering paperCoatingsCalcium carbonatePolyacrylamide
The invention belongs to the field of transfer paper and particularly relates to a piece of thermal sublimation and transfer digital paper with high ink suction amount. The thermal sublimation and transfer digital paper comprises a piece of substrate paper, a hydrophobic layer coated on the surface of the substrate paper, an ink suction layer coated on the surface of the hydrophobic layer, and a surface layer on the upper surface of the ink suction layer. In terms of calculation by weight, the ink suction layer is a composite material of an inorganic material and cationic polyacrylamide cellulose interpenetrating network resin, wherein the inorganic material is one or a combination of two of porous silicon dioxide or porous calcium carbonate or porous alumina. The hydrophobic layer is organosilicone modified acrylic resin. According to the thermal sublimation and transfer digital paper, the composition material which is one or the combination of two of the porous silicon dioxide or the porous calcium carbonate or the porous alumina is added into the ink suction layer, the solid porous structure can rapidly and sufficiently absorb dye molecules, and the ink suction amount of the thermal sublimation and transfer digital paper is remarkably increased.

Finger print structure in digital products, its authentication and digital products issue system

InactiveCN1834973AEnhanced construction flexibility and fingerprint security and robustnessImprove reliabilityProgram/content distribution protectionMarketingSystem safetyFingerprint
The invention relates to an in-digital product fingerprint constructing and verifying method, and the constructing method obtains purchase secret information from a purchaser, and uses a copyright server to construct an evidence fingerprint unable to be forged, and then uses a copyright issuing server to construct an ID fingerprint with license issued by the copyright server and sale information, and finally adopts fusion technique to construct a fingerprint-containing copy. And the verifying method extracts the ID fingerprint stored in the digital product to check the product license and identify the ID of the purchaser, and then checks and confirms the belonging relation by comparability of the evidence fingerprint. Correspondingly, the invention provides a digital product issuing system, comprising purchasing device, copyright issuing server and copyright server. And it provides a user-friendly and simple-to-apply method, largely improving safety and extendibility of the existing system.

Nanometer silver wire conductive silver paste and preparing method thereof

The invention discloses a nanometer silver wire conductive silver paste. According to the nanometer silver wire conductive silver paste, nanometer silver wires are used for replacing silver powder on the basis of conventional conductive silver paste. The nanometer silver wire conductive silver paste comprises 28 wt%-32 wt% of conductive silver wires, 25 wt%-40 wt% of resin, 20 wt%-30 wt% of organic solvents, 1 wt%-10 wt% of glass powder and 1 wt%-10 wt% of additives. The small quantity of the nanometer silver wires replace 65 wt% to 75 wt% of silver powder in the conventional conductive silver paste, cost is reduced, and the nanometer silver wires can form a good conductive network so that resistance can be reduced and the electrical conductivity can be improved. Besides, because metal silver content is reduced, the cohesiveness of the prepared conductive silver paste is improved to a certain extent. The combined additives of 20 wt% of carbon nanotubes, 20 wt% of carbon fibers, 20 wt% of nanometer palygorskite, 10 wt% of polyether diol and 30 wt% of tetraethyl titanate are added in, and therefore the conductivity of the conductive silver paste is optimized better while the processability of the conductive silver paste is guaranteed.

Nitrogen/fluorine-doped titanium dioxide photocatalyst and application thereof in degrading organic pollutants under visible light

The invention relates to a nitrogen / fluorine-doped titanium dioxide photocatalyst and application thereof in degrading organic pollutants under visible light. The technical scheme is as follows: the preparation method comprises the following steps: while evenly stirring, slowly and dropwisely adding tetrabutyl titanate into an ethanol-glacial acetic acid mixed solution, dropwisely adding a hydrofluoric acid solution, and stirring to form a transparent mixed solution A; mixing ammonia water and ethanol, and regulating the pH value to 2 to obtain a solution B; slowly and dropwisely adding the solution B into the solution A to obtain a uniform and transparent sol; aging the uniform and transparent collosol in air to obtain a solid gel; and drying, grinding into powder, and roasting in a muffle furnace at 400-500 DEG C for 40 minutes to 1.5 hours, thereby obtaining the nitrogen / fluorine-doped titanium dioxide photocatalyst. The invention widens the visible light response range of TiO2, and reduces the combination of electrons and holes, thereby increasing the utilization ratio of TiO2 for solar power and enhancing the photocatalytic activity.
