An inkjet printing fluid composition comprising water, colorant, acrylic latex polymer, and a water dispersible polyurethane additive having an acid number greater than 50, preferably between 50 and 150, more preferably from 60 to 100, and most preferably from 60 to 90. The invention provides inkjet printing fluid compositions, such as pigment-based inkjet printing inks, which contain an acrylic latex polymer which provides increased optical density for printed images, and a water dispersible polyurethane additive that enables the latex-containing printing fluid to be recirculated for extended periods in a recirculating printing fluid printing system without significant fluid destabilization or pressure build up or filter clogging. The invention further provides a method for printing an inkjet image comprising: I) providing an inkjet printing fluid according to the invention; and II) jetting the inkjet printing fluid in the form of ink drops onto a recording element to form a printed image.

The invention discloses a colorful acid and alkali resistant laser printing ink and a preparation method thereof. The printing ink is composed of the following components in parts by weight: 0 to 30 parts of butanone, 10 to 30 parts of isopropanol, 2 to 6 parts of curing agent, 10 to 15 parts of pigment, and 10 to 30 parts of glycidyl ether epoxy resin. The glycidyl ether epoxy resin is adopted to produce the printing ink, aliphatic polyamine is further chosen as the curing agent, the acid and alkali resistant performance of the printing ink is strengthened through optimizing the formula, thus the shortage that the colorful laser printing ink is lost when being mixed with acid and alkali is overcome, moreover, the color of the laser printing product is more abundant, and the patterns are more clear.

The invention discloses a partially-aluminized packaging film and a manufacturing method thereof. The partially-aluminized packaging film structurally comprises a transparent plastic film, an aluminizing layer and a printing ink layer, wherein the plastic film is made of any one material of OPP, BOPP and PET, and the aluminizing layer is provided with at least one opening. The manufacturing method of the partially-aluminized packaging film includes the following process of coating of a water-based complex adhesive, vacuum aluminizing, washing and printing, wherein any water-based complex adhesive for food packaging can serve as the water-based complex adhesive, and any of offset printing, intaglio printing and silk-screen printing can be adopted as the printing mode. The partially-aluminized packaging film has the advantages that the manufacturing process is simple, cost is low, and no pollution is generated.

The invention discloses a rotary lifting type printing ink conveying plate tank device which comprises a bottom plate. A rotary column is arranged above the bottom plate, a guide rod is arranged on the bottom plate, the guide rod is an external threaded rod, a sleeve is arranged at the bottom of the rotary column, the sleeve is an internal threaded rod, the sleeve is in threaded matching connection with the guide rod, a support column is arranged on the rotary column, the sleeve, the rotary column and the support column are arranged in a cross shape, and a storage plate is arranged on the support column. The storage plate is horizontally arranged, the storage plate is provided with a plurality of printing ink storage tanks, the printing ink storage tanks are in a cylindrical shape, the plurality of printing ink storage tanks are arranged on the storage plate side by side, the two ends of the bottom plate are provided with a third tensioning wheel and a fourth tensioning wheel correspondingly, the two ends of the storage plate are provided with a first tensioning wheel and a second tensioning wheel correspondingly, and the first tensioning wheel, the second tensioning wheel, the third tensioning wheel and the fourth tensioning wheel are connected through tensioning ropes. The printing ink storage tank is used for storing printing ink, so that an up-down lifting function can be realized, and the printing ink can be conveyed more conveniently.

The invention relates to a method for improving the stability of an organic silicon emulsion, raw materials for preparing the emulsion comprise polysiloxane, polyether modified polysiloxane, a cross-linking agent, a basic catalyst, silicon dioxide, an emulsifier, a thickener, water and a preservative, and the emulsion is obtained by polymerization, cross-linking, grinding and dispersion. Compared with an emulsion prepared by a common method, the organic silicon emulsion has more excellent high-temperature resistance, low-temperature resistance, dilution resistance and shear resistance, and can be used in the fields of buildings, electronics and electrics, textiles, automobiles, machinery, leather, papermaking, metal processing, printing ink, coatings and the like.

The invention provides efficient and accurate daily porcelain 3D soft silica gel transfer printing ink and application thereof. The printing ink is prepared from 100 parts of stamp-pad ink and 60-120 parts of ceramic toner, the stamp-pad ink is prepared from the following components: 80 to 120 parts of sodium polyacrylate-aluminum sol composite liquid, 10 to 15 parts of thermocuring phenolic resin, 3 to 5 parts of guar gum, 5 to 10 parts of tripolyglycerol, 3 to 6 parts of Span 60 and 1.5 to 3 parts of castor oil. The printing ink has balanced plate-sticking, glue-sticking and ceramic-sticking performance and plate-separating and glue-separating performance, the transfer printing speed is high, the precision is high, the adaptability to the performance of domestic porcelain glaze is good, and the transfer printing effect is basically not affected by environment temperature and humidity fluctuation; and the printed and fired ornamentation is accurate in color, fine in line and clear in edge.
