The soluble carrier of water-based plastic composite ink is water. Because water is used as the soluble carrier, water-based plastic composite ink has significant environmental protection and safety characteristics. It is safe, non-toxic, non-flammable and non-explosive, and almost no volatile organic gas is generated. No pollution to the atmosphere because of water-based plastic composite ink water as a solution carrier, so whether in its production process, or used for printing, almost no volatile organic gas to the atmosphere. Reduce print surface residual poisons to ensure food health and safety water-based plastic composite ink completely solves the toxicity problem of solvent-based ink, because it does not contain organic solvents, so that the print surface residual toxic substances are greatly reduced, this feature in tobacco, wine, food and beverage drugs Children's toys and other hygienic conditions require strict packaging and printing products reflect a good health and safety. Reduce resource consumption and reduce environmental protection costs due to the inherent characteristics of water-based plastic composite ink with higher isomorphic content, can be deposited in a thinner ink film, printing the same number and specifications of printed matter, water-based plastic composite ink consumption is reduced compared with solvent-based ink. To improve the safety of the working environment and ensure the operating personnel contact the health of the solvent in the manufacturing process and during printing ink is pretty dangerous, organic solvents and solvent ink itself is flammable liquid, organic solvent is quite volatile, can form explosive mixture gas in the air, after reaching concentration explosive limits in that Mars will explode Therefore, the risk of fire and explosion in the production environment is quite high, and the use of water-based plastic composite ink fundamentally avoids such risks.

Water-based ink resin is the carrier of pigment in ink, is the core material of ink, its quality, will directly affect the performance of ink, because water-based ink resin to a large extent determines the viscosity of ink, dry fluidity and other properties.Anti - viscosity is an important physical property index of printing ink.Intaglio printing is a kind of printing with high order ink supply, good reproducibility and fast printing speed.After the ink plate transfer to the substrate, through the drying channel, to be fast volatile organic solvent drying that rewinding. As we all know, through high temperature drying after rewinding, printing film surface temperature is generally between 40 ~60, at the same time because of the existence of rewinding pressure, if the ink itself anti anti viscosity is not good, it will lead to serious rewinding adhesion quality accident, causing irreparable economic losses to ink customers In addition to the thoroughness of solvent gradient volatilization in the printing process, the anti-viscosity of ink is also directly related to the film formation and molecular properties of water-based ink resin.Good film forming water-based ink resin can give the ink good dry, in the solvent volatilization and thorough drying, film forming thoroughly, after winding anti anti viscosity excellent.

What is water-based adhesive Water-based adhesives are environmentally friendly adhesives made of natural or synthetic macromolecule as adhesives and water as solvent or dispersant instead of toxic organic solvents that pollute the environment.Existing water-based adhesives are not 100% solvent-free and may contain limited vocs as additives for their aqueous media in order to control viscosity or fluidity.Advantages are mainly non-toxic, pollution-free, non-burning, safe and easy to achieve clean production process, etc. Disadvantages include slow drying speed, poor water resistance and poor anti-freezing. The water based adhesive series has become a hot product of Sinograce Chemical.Sinograce Chemical's adhesive binder is commonly praised in the market due to good materials, fine workmanship, reliable quality, and favorable price.As for customer service management, Sinograce Chemical insists on combining standardized service with personalized service, so as to fulfill different needs of customers. This enables us to build a good corporate image.This is our email sales@sinogracechem.com, welcome to consult.

The most important application indexes of water-based adhesives in the packaging and printing industry mainly include four aspects: bonding strength, high/low temperature resistance, moisture resistance and viscosity holding.In practical application, defects such as weak adhesion and brittle degumming film are basically caused by the above four application indicators are not up to standard.In practical application, defects such as weak adhesion and brittle degumming film are basically caused by the above four application indicators are not up to standard.When choosing water-based adhesive, quality first and price second should be the principle. However, some packaging and printing enterprises have a one-sided view, mistakenly thinking that the higher the price of water-based adhesive, the better the quality; The other way around, the worse the quality actually, it's not absolute.When choosing water-based adhesives, we should first understand the characteristics of processed products and choose adhesives with higher cost performance, which is a reasonable way to choose and buy. The solid content of modified waterborne polyurethane adhesive sold in the market is generally 15%-35%, which increases the cost of transportation and drying, and affects the bonding property.So how to improve the solid content has become a hot research topic at home and abroad.At present, sulfonates are mainly used as hydrophilic chain extenders in the synthesis of water-based polyurethane with high solid content, and carbonates and carboxylate are also used as hydrophilic chain extenders.By introducing the ionic group (-COOH) to the end of the molecular chain through molecular design, stable waterborne polyurethane with low ionic group content and high solid content is prepared, which also provides a new idea for the development of waterborne polyurethane with high solid content.UV curing modified waterborne polyurethane adhesive with water as diluent, non-flammable environmental protection; And does not contain dilute monomer, is conducive to improve the adhesion of the film to the substrate.So get vigorous development in recent years Natural polymer modified waterborne polyurethane modified, such as nano cellulose fiber is one of the most abundant natural polymer materials in the nature, and nanometer fiber has higher strength of the modified waterborne polyurethane can not only reduce the cost, but also can obtain very good mechanical properties. With economic development, China's annual use of adhesives up to 600,000 tons, more than 90% of solvent-based adhesives, such adhesives contain a lot of toluene xylene butanone acetone ethyl acetate alkane and other organic solvents, the amount of glue accounted for 80% or more of the total weight.These organic solvents have certain toxicity, and some inferior adhesives are even produced with benzene, which is more toxic.These organic solvents have a certain toxicity, some inferior adhesives even use benzene to produce, its mo...
