< p > Description: solvent based surface treatment agents are commonly used in leather making and synthetic leather industry both at home and abroad. The solvents used are: butanone, toluene, xylene, two methyl formamide, cyclohexanone, and so on. < /p >
< p > < a > href= > //m.pmae.cn/news/index_c.asp > solvent > /a > surface treatment agent and diluent. The toxic and harmful solvent content is about 90%, which is directly discharged into the atmosphere when used. < /p >
< p > development of environmentally friendly sanitary surface treatment agent is the research focus and development direction of this industry. However, due to the difficulty of technology, there are few successful examples at home and abroad. < /p >
< p > the largest surface treatment plant in the world, the waterborne surface treatment agent developed by Stehr, USA, has the defects of difficult construction, poor leveling, hard drying and high price. < /p >
"P" and some of the domestic water-based surface treatment agents for synthetic leather and synthetic leather, which also have poor adhesion and hard drying, are difficult to be widely promoted. < /p >
< p > < < a href= > //m.pmae.cn/news/index_c.asp > Artificial Leather > /a > a href= > //m.pmae.cn/news/index_c.asp > synthetic leather > /a > surface treatment agent with environmentally friendly and hygienic alcohol solvent. It has the advantages of no change in user habits, strong adhesion, quick drying, excellent appearance performance and low cost. Only plant 500m2, power 150KW, equipment investment less than 2 million yuan. Gross profit margin 5000 yuan / ton. < /p >

< p > in view of the problems of flammability and brittleness existing in PLA at present, a PLA flame retardant chain extender is prepared by means of synthetic reaction flame retardant chain extender. < /p >
< p > by introducing a small number of reactive halogen-free flame retardants and nanocomposite technology, the flame retardant polylactic acid with excellent flame retardancy is obtained. The results show that the flame retardant polylactic acid, compared with the ordinary additive flame retardant on the market, shows little influence on the mechanical properties of the matrix, and has high flame retardant efficiency. < /p >
< p > and through the compound toughening technology, the flame retardant polylactic acid has good toughness. The new technology has made the polylactic acid high added value, excellent performance and suitable for electronic and electrical products. < /p >
< p > application area and market demand analysis: the product can be applied to the field of electronic and electrical appliances, automobile industry and so on. Because of its high technology content, good flame retardancy and excellent mechanical properties, it is an environmentally friendly and high-performance plastic product with market competitiveness and can create enormous economic and social benefits. < /p >
