The Nano-Polypropylene Pipe Special Materials (NPP-R) jointly developed by Chengdu Zhengguang Technology Co., Ltd. and the State Key Laboratory of Engineering Plastics, Institute of Chemistry, Chinese Academy of Sciences, passed the technical appraisal organized by Sichuan Science and Technology Agency in Chengdu on August 16th. . Academician Wang Fosong, Member of the Standing Committee of the National People's Congress and Vice President of the Chinese Academy of Sciences, Professor Zeng Zongneng, Chief Scientist of Zhengguang Science and Technology Institute, Professor of the Institute of Chemistry of the Chinese Academy of Sciences, Professor Cai Xingxian of the College of Polymer Science and Technology of Sichuan University, and other well-known experts in nanotechnology and polymer materials participated in the appraisal At the meeting, experts gave extremely high evaluations on the application of nanometer-scale polypropylene pipe materials.
According to reports, this nano-polypropylene pipe special material preparation principle is the use of intercalation composite technology, the inorganic montmorillonite by organic treatment, with melt intercalation method, with nano-size uniform dispersion in the polypropylene matrix to form polypropylene nanometer Composite material. Due to the nano size effect of organic montmorillonite dispersed in polypropylene, the combination of large specific surface area and strong interface, the special material for nano-polypropylene pipe shows a particularly excellent technical performance, and is a new high-tech new material.
Experts of the appraisal committee unanimously believed that this special material for polypropylene pipe made with nanotechnology is the first in the country and its performance has reached the international advanced level. It can replace the imported PP-R pipe special material and has unique bactericidal function, so it is extremely A wide range of applications. Nano PPR will be mainly used in construction areas such as hot and cold water pipes, drinking water pipes, floor heating pipes, especially plastic covers for sanitary wares; automotive fields such as steering wheels, dashboards, body covers, etc.; civil and military helmets; and The use of modified polypropylene products can also be replaced with nano-PPR; in particular applications requiring sterilization.
With the rapid development of the domestic construction industry, there are 250-300 million meters of hot and cold water pipes every year that require the use of high-performance plastics. At present, most of the polymer-specific materials used in hot and cold water pipes, drinking water pipes, and automobile plastic products produced in China are imported, and such special materials do not have bactericidal functions. The National Chemical Industry Synthetic Resins and Plastics Quality Supervision and Inspection Center and the Sichuan Province Product Quality Supervision and Inspection Institute have verified that such nano-polypropylene pipe special materials and their pipe materials have exceeded the import in terms of strength, heat resistance, anti-shrinkage and other technical indicators. PP-R material. Tested by the Sichuan Provincial Health and Anti-epidemic Station, the material has a unique bactericidal function, the sterilization rate reached 100%.
Xue Jinglun, Chairman of Zhengguang Technology Company, Vice Chairman Rong Changrong, and Wang Jin, Deputy General Manager Wu Tinglu and other company leaders and technical experts attended the appraisal meeting.
