Water -based optical oil refers to a liquid that uses water as a carrier and is painted online with a printing machine online or an upper light machine to increase the gloss, water resistance, and abrasion resistance of paper printing.At present, coating technology has been adopted by more and more printing manufacturers, which has prompted the demand for optical oil to continue to rise.Due to the discharge, low cost, low cost, and wide source of raw materials due to the hydrophilic oil that is non -toxic, odorless, strong, transparent, and no organic volatilization (VOC).Abrasion resistance and chemical resistance.
Water -based optical oil technology
Water -based light oil, it is actually a liquid.When using it, it also relies on water as a carrier, which is mainly used on the printing machine or on the light machine.Its position in the market is becoming more and more important, and it has been used more and more frequently.Water -based optical oil, we can divide it into three types according to the purpose of its products, namely high gloss, ordinary luster, and sub -gloss.Secondly, we can also divide it into four types according to its processing technology, namely the light technology, the light technology of the water bucket, the dedicated light machine on the light, and the online light process.
Water -based optical oil price
The price of water -based optical oil is generally about 20 yuan per kilogram.Pay attention to the following points in use: (1) Paper quantity requirements.Because the paper will absorb water after the light, the low amount of paper will be easily deformation after light. If the two sides are on the two sides, the paper volume is generally required to be more than 135g/m2.(2) Requirements for printing ink.Due to the weak alkalinity of water -based optical oil, the ink with poor alkali resistance will cause color problems such as discoloration and insufficient sharpness of the outlets. Therefore, during use, you should try to choose ink with good alkali resistance.
Water -based optical oil formula
Water -based optical oil is mainly composed of three categories: main agent, solvent, and auxiliary agent.a. Main agent.The main agent of water -based light oil is film formation resin, which is the film formation substance of an optical agent. It is usually synthetic resin. It affects and supports the various physical properties and the light quality of the film layer, such as gloss, attachmentSexuality, dryness, etc.b. Additive.The auxiliary is to improve the physical and chemical performance and processing characteristics of water -based optical agents.The types of auxiliary are: curing agent.Improve the film formability of water -based main agents, increase the intensity of the membrane layer; surface active agent.Reduce the surface tension of water -based solvents and improve flowing; foaming agent.It can control the foam of the upper light agent to eliminate the quality defects such as fish eyes and pinhole; desiccant.Increase the drying speed of the water -based photonic agent and improve the adhesive of paper seals; adhesives.Improve the adhesion capacity of membrane substances and printers; wet decentrals.Improve the decentralization of the main agent, prevent dirt and abrasion resistance; other additives are plasticizers that can improve fold resistance.c. Solvent.The main role of solvent is decentralized or dissolved synthetic resin and various additives.
