Water - based ink is also known as water - based (oil) ink, referred to as ink.Water-based ink is made of water-soluble or water-dispersed polymer resin, colorant, surfactant and other related additives through chemical process and physical processing. Water - based ink containing a small amount of alcohol water as solvent, ink stability.Therefore, it is especially suitable for food, medicine and other packaging industries. Water-based ink can be cleaned with water, non-flammable, non-explosive, no adverse effects on the atmospheric environment and the health of workers, and no fire hazards caused by static electricity and flammable solvents, with production safety. Water-based ink is a new type of printing ink with high color concentration, no longer soluble, good gloss, strong printability, good leveling and high solid content.Water-based ink is easy to operate. In printing, only according to the demand in advance to add tap water allocation of good ink. In the printing process directly add a proper amount of new ink, do not need to add additional water solvent, can prevent the color of different shades. Water-based ink dry after the general no longer soluble in water. When printing, the printing plate must be immersed in the water-based ink to keep rotating at all times. Otherwise, the water-based ink on the printing plate will dry quickly, causing the plate roller to be blocked, resulting in the inability to print. In view of the increasing price of organic solvents caused by the depletion of petroleum resources, the cost of solvent ink production and environmental use will be increasing. The solvent of water-based ink mainly uses tap water, and because of the high concentration of water-based ink, gravure printing depth can be shallow. Therefore, from the cost point of view, although the price of water-based ink is high, its comprehensive use cost is estimated to save about 30% than solvent ink, and there are few concerns about residual toxicity of solvents on the surface of printing materials. Water-based ink has successfully explored the application of plastic intaglio printing, which is undoubtedly a good news for color printing and packaging factories.

The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will make the defoaming work of high viscosity ink especially difficult, this type of ink has its own special defoaming agent.The drying time of ink film is closely related to the selection of defoamer. In the printing process, the ink film is required to dry quickly, so the defoaming agent with strong defoaming power should be selected in ink painting. Latex ink has a high pH value.Not good for controlling bubbles.Emulsion polymer is used as film forming agent in acrylic ink, usually the particle of emulsion is very fine, resulting in defoaming work is difficult.Pigment particles such as carbon black, phthalocyanine blue and phthalocyanine green organic pigments have a tendency to increase foam in water-based ink, which is also caused by the pigment particles are too fine, and defoaming is also difficult. Because many defoamer will affect the dispersion of pigment, pigment particles will adsorb defoamer particles, so the selection of defoamer, storage stability test must be carried out.The addition of filler in ink and wash also affects the existence of foam, for example, the use of silica instead of talc foam will increase. But this problem can be solved by increasing the amount of antifoaming agent.

Water-based adhesion enhancer Product introduction Water-based adhesion enhancer, a water-based chlorinated PP acrylic emulsion, used to improve the adhesion effect of water-based paint and ink on polypropylene (PP) material. Suitable for PP substrate, can do bottom, surface coating paint. Product specifications Composition: acrylic modified emulsion Appearance: Milky white viscous liquid Non-volatile: 38-40% Solvent: Water Specific gravity: 1.03 PH value: 7-9 Viscosity (mPa.s) : 100 ~ 1000 TG: 65 Product feature Improve the adhesion effect of PP material, good adhesion to special PP plastic substrate, as adhesion base, paint resin. High gloss, chemical resistance, weather resistance and water resistance Pigment wetting dispersion is good, high hardness; Abrasive color paste. Water - based sealing varnish, solvent - based varnish, UV - curing varnish. Applications Waterborne coatings and inks for PP Adding method and amount Directly as the only resin or with other resins for the manufacture of PP primer, before use to test compatibility and add amount. Curing conditions: Thin coating or brush can be self-drying. Performance guarantee, the need for low temperature 75-85 degrees bake for 30 minutes to form a good film. High temperature about 120 degrees Celsius baking time can be shortened. Additive amount Alone as a resin or account for 35-80% of the total resin Packaging Net weight 25kg/50kg store If the container is sealed in a cool, dry and ventilated place below 35℃, the shelf life will be significantly shortened under high temperature or exposure. The shelf life is six months from the production date without opening the can.

Polyurethane is the short form of polyurethane (PU). It is a block polymer formed by addition polymerization. It is a polymer compound with flexible and elastic polyether or polyester as soft segment and rigid and hard carbamate as hard segment. It contains a considerable number of ammonia ester bonds. Waterborne polyurethane has been successfully applied in the textile printing and dyeing industry, it can give fabrics excellent softness, fullness, wash resistance, wear resistance, good resilience, smooth, good feel, antistatic, etc. Waterborne polyurethane in textiles mainly plays the following roles. Waterproof and permeable coating agent Waterborne polyurethane film forming property is good, the fabric after coating finish can form a durable film, has better water resistance, water droplets are not easy to penetrate, because the molecular structure of waterborne polyurethane contains more polar groups, water vapor can be diffused to the surface through the polyurethane amorphous area, so that the coated fabric has waterproof and moisture permeability function, can be used to manufacture clothing, raincoat, tent and other textiles. At the same time, it can be crosslinked with functional groups such as hydroxyl to improve the washing resistance. After forming a film, the fabric is more tightly organized and the gap is closed. After making a down jacket, pillowcase and quilt, the feathers are not easy to Pierce out. Wash and wear finisher In the traditional process, most of the anti-wrinkle finishing agents used are formaldehyde finishing agents. This finishing agent is harmful to the ecological environment and human body, and there are serious problems of fabric damage. Low molecular weight carbamate - based block copolymerization of elastic polymers can meet people's needs. This resin does not contain formaldehyde, has good film forming property and elasticity, is expected to give the fabric a certain wrinkle resistance, and improve the strength of the fabric, can greatly improve the wrinkle recovery Angle of finishing, wear resistance, and give the fabric excellent feel, it is effective on cotton, polyester cotton, polyester viscose and other fibers. Anti-shrinkage finishing agent for wool There are many resins used for wool shrinkage finishing, such as polyurethane, polyamide surface chlorol condensation, polyacrylate, polysiloxane and so on. Polyurethane anti-shrinkage agent finishing can be in place in one step, no pollution, anti-shrinkage agent molecular chain contains active groups, after finishing the surface of the wool fiber formed with a cross-linked network structure of polymer film, and the wool fiber between the chemical bond connection, so it has excellent anti-shrinkage effect, and anti-shrinkage durability is quite good. Anti-pilling agent Resin finishing is an effective way to improve the resistance of fabric to fuzz and pilling. The principle is that the fiber surface is coated with a layer of wear-resistant resin film, and t...
