Information
  In December 2019, the company signed a long-term strategic cooperation agreement with the Institute of Process Technology, Chinese Academy of Sciences, and adopted advanced ionic liquid method (prepolymer and polymer are dissolved in ionic liquid to prepare a membrane solution) to develop and develop high-grade melamine film , Film.
  The research and development of this project is led by Academician Zhang Suojiang of the Institute of Processes of the Chinese Academy of Sciences, and Dr. Xiangping Zhang, Dr. Nie Yi, and Dr. Zeng Shaojuan are the deputy team leaders, leading 8 R&D personnel including Sun Yikai, forming the domestic top ionic liquid R&D, melamine fiber, and high-end packaging R&D. With the application team, Chen Defu, General Manager of Sainty Chemical Company, is the project leader, and the R&D department, technical department, equipment department and finance department are members of the R&D team to jointly establish a R&D group to jointly promote the research and development of this project. The project established a small-scale research and development platform in the Zhengzhou branch of the Institute of Process Engineering of the Chinese Academy of Sciences, and established a film tensile test production line in the Hengshui Institute.
  As a major agricultural country, my country's agricultural plastic film output ranks first in the world, with an annual output of about 600,000 tons of mulching film, and an area of ​​about 144.7 million hectares covered by mulching film. However, due to the consideration of production cost and economy, my country's commercial agricultural mulch films are mainly PE, PVC and other extremely difficult-to-degrade plastic films. With the large-scale use of plastic mulches, the accumulation of discarded plastic mulches in cultivated land is increasing. , Not only affects the agricultural ecological environment, but also forms a barrier layer in the soil, reduces soil permeability, hinders the development of crop roots and the absorption of water and nutrients in the soil, resulting in a serious reduction in crop production. Therefore, in order to solve the pollution problem of the remaining plastic film on the soil, the degradable agricultural film with the same function has attracted more and more attention. However, the current commercially available degradable films have the problems of processing difficulties, poor mechanical properties and poor water resistance. .
  Moreover, melamine has flame-retardant and insulating properties. If it is made into a high-grade melamine film and used as agricultural mulch, it is of great significance to reduce fire accidents in agricultural production and protect people's lives and property.
This project uses melamine as the basic raw material to replace the polyethylene raw materials on the market. It is transformed into a film with high temperature resistance characteristics through ionic liquid preparation, chemical synthesis, raw material blending, and green film forming technology. After the adjustment of the process method, It can realize the production of packaging film and agricultural film.
The prepared high-grade melamine film has the functions of flame retardant, insulation and degradability. After the research and development is successful, the dosage of melamine added is ≥50%, the limiting oxygen index (LOI) flame retardant performance is ≥25%, self-extinguishing from fire, and film tensile load Reaching 1.5N, it can be completely degraded within half a year to 1 year. The process technology is advanced, which is the first domestic research and development, the cost of raw materials is low, and the production process is green and environmentally friendly. Has the following advantages:
  1. The green synthesis process technology of ionic liquid method newly developed by the Institute of Process Technology of Chinese Academy of Sciences is adopted, and the production process is environmentally friendly;
  2. Melamine film has the characteristics of flame retardant and high temperature resistance, the use temperature is greater than 150℃, 300℃ does not melt or shrink;
  3. The melamine film does not contain plasticizers, is non-toxic and harmless, and no additives ooze out during use;
  4. Melamine film is degradable and can be completely degraded within six months to one year, which can effectively solve the problem of soil pollution caused by residual plastic film.
  5. Compared with the traditional film production process, the melamine film has low raw material consumption, which can effectively reduce production costs, reduce farmers' planting costs, and improve market competitiveness.
  The R&D and application project of high-grade melamine packaging film is a domestic initiative. First, it can effectively develop melamine middle and downstream products, broaden the application market of melamine products, and solve the problems in the development of middle and downstream products in the melamine industry. Second, use domestic advanced ionic liquid spinning. Technology and degradable plastic film production technology, the produced melamine film has high-quality properties of flame retardancy, insulation and degradability, which can effectively replace polyethylene raw materials and reduce film production costs.
