Now, people's environmental awareness is getting stronger and stronger, and many glue manufacturers are also seeking to transform themselves. Some water-based glue or oil-based glue are produced. Today, we will take water-based glue and oil-based glue as an example to talk about the difference between them. First, the difference between water-based glue and oily glue The first difference is that their solvents are different. The main solvent of water-based watering is water, and acrylic acid, etc., which is made into a kind of glue. And the main solvent of oily glue is oily solvent, toluene, and acrylic acid dissolved. The second difference is the environmental performance. The environmental performance of water-based glue is more prominent than that of oily glue, mainly because oily glue uses oily solvent. If you use a poor oily solvent, it will cause pollution to the environment, and the solvent of water-based glue is relatively healthy and environmentally friendly. The third difference is that the price is different. It is because of their different solvents that the price of oily glue is slightly more expensive and the cost is larger. Two, Oily glue is good or bad The viscosity of oily glue will be prominent. Another advantage is that if you accidentally touch our hands, you can flush them with water after using them. If you compare the degree of adhesion between the two, the strength of oily glue does not transfer water glue, drop a drop can solidify, do not need to paste repeatedly, later is not easy to fall off the phenomenon. And after sticking, even if it comes into contact with water, it is not easy to crack, so the range of application is very wide. Conclusion: Through analysis, I believe that we have a deeper understanding of the difference between water-based adhesive and oily adhesive, mainly in the solvent and environmental performance and price.

Pressure sensitive adhesive in addition to the adhesive, but also to add adhesive and other auxiliary substances. 1.The adhesive of the pressure sensitive adhesive has rubber or synthetic resin and other materials, its role is to give the adhesive layer enough cohesion strength and adhesion, the dosage is 30%-50%. 2.Viscosifier. Viscosifier rosin and its derivatives, petroleum resin, etc., its role is to increase the adhesive layer adhesion. Its dosage is 20% to 40%. 3.Plasticizer. The plasticizer used is the plasticizer used for general plastic processing, and its role is to increase the fast viscosity of the adhesive layer. Its dosage is 0-10%. 4.Anti-aging agent. General rubber, plastic antiaging agent can be used, the role is to improve the service life, the dosage is 0-2%. 5. Packing. The filler used is the general plastic filler, the effect is to improve the cohesion strength of the rubber layer, reduce the cost, the dosage is 0-40%. In addition, some pressure sensitive adhesive, also need to add viscosity regulator, vulcanizing agent and solvent.

Due to the printing speed is too fast, add too much, high hardness of tap water, ink solvent surface tension size is different, excessive circulation stirring and other reasons lead to the production of foam, ink texture is uniform to ensure printing quality, bubble is destroyed uniformity, will reduce production efficiency.After the foam overflow in the tank, the foam flows into the roller, wet the printing paper, and the printing press cannot work normally. Ink printing industry use common problems 1.Ink texture uniform to ensure printing quality, bubbles that destroy the uniformity 2.Causes the printing surface defect, causes the printing paper the pattern cannot print the complete 3.After the foam overflow in the tank, the foam flows into the roller, wet the printing paper, and the printing press cannot work normally 4.Will the original performance be lost after adding antifoaming agent (such as insufficient viscosity, late fading) 5.The dispersion is not good, the solubility is not strong, and the stock solution is not very good Will it change the original color of the product

Compared with traditional glue, water-based coated glue is made of imported raw materials, with high solid content, low viscosity, good process applicability, strong adhesive force, non-toxic and other advantages are suitable for aluminum foil (OPA), pretreated polyethylene (HDPE,LDPE), polypropylene (OPP, CPP), polyester (PET), polyamide (PA,ONY) film, A two-component solvent-based polyurethane adhesive coated with metal film and cellophane. Use can enhance the brightness of printed matter, increase the light resistance of printed ink, increase the ability of ink layer to prevent heat and moisture, play a role in protecting blot and beautifying products. The water-based laminating glue has environmental protection and no pollution, so that the high quality of waterproof performance makes it widely trusted by consumers.
