New environmentally friendly product of polyurethane resin: alcohol soluble polyurethane resin

　　The project product"alcohol soluble polyurethane resin"developed by the Shanxi Institute of Applied Chemistry uses"green solvent"ethanol as the solvent,which can reduce environmental pollution and human harm.It is currently an environmentally safe and less harmful gravure printing ink resin,which is in line with the development trend of green,environmentally friendly,and health safe food and pharmaceutical packaging materials.The project product has completed pilot production and has high cost-effectiveness,It can form favorable competition with similar products and create better social and economic benefits.At the same time,it meets the market demand for environmental protection in the packaging and printing industry,and has broad prospects for promotion and application.It has a good promoting effect on the development of the packaging and printing industry in our province,and also contributes to the development of functional polymer materials in our province.

　　With the development of the economy and social progress,people not only pay attention to the safety and hygiene of food and drugs themselves,but also put forward higher requirements for the safety and hygiene of food and drug packaging materials and environmental protection during production.

　　At present,the main printing inks in Shanxi Province are mainly lithographic and gravure inks,with gravure ink enterprises mainly concentrated in the southern and central parts of our province.The ink products are mostly ketone soluble and ester soluble.The widespread use of solvents with relatively high toxicity has brought certain pressure to the development of the environment,ecology,human health,and related industries in our province.Under the industrial adjustment and urgent demand for environmental protection,health and safety in our province,as well as the market competition of the ink industry itself,some ink manufacturers are gradually developing and producing alcohol based polyurethane ink,but a considerable portion of the polyurethane resin produced by ink manufacturers comes from other provinces and foreign products.
