Green plastic flame retardant masterbatch has made a major breakthrough

In recent years, with the improvement of environmental protection awareness, environmentally friendly plastic flame retardant masterbatches have become the development trend of flame retardant technology. It is understood that the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences and Zhejiang Fenghong New Materials Co., Ltd. jointly established the "Zhongke-Fenghong Functional Organoclay Engineering Technology Research and Development Center" to develop the preparation technology of flame-retardant functional clay and its application in polymers. Since the establishment of the center, under the leadership of associate researcher Li Juan and researcher Xue Lixin, the research work of green plastic flame retardant masterbatch for nylon 6 has been carried out.

After more than a year of research, we have mastered the flame retardant modification technology of clay, successfully obtained two kinds of flame retardant functionalized clay, and developed a special green plastic flame retardant masterbatch for nylon 6. Under the condition that the flame retardant content is less than 10%, its LOI reaches 29, and its vertical combustion reaches V-0 level. Due to the reduction of the content of the flame retardant, other properties of the flame retardant nylon material are effectively improved. Compared with similar products on the market, it has the advantages of high efficiency and low cost. It is estimated that the cost can be reduced by 4,000-8,000 yuan per ton, and it has strong competitiveness. At present, the laboratory test has been completed, and the pilot test and industrialization are being promoted. .

The development of green and environmentally friendly flame-retardant organic functional clay/nylon plastic flame-retardant masterbatch mainly provides one-stop service for modified material manufacturers in Zhejiang Province and even the whole country, saving the energy of the majority of downstream manufacturers, and hereby On the basis of continuous improvement and development of a series of products. This achievement is applying for a patent, and it will promote the development of high-efficiency, halogen-free, low-smoke, low-toxicity, and anti-melting droplet environmentally friendly flame retardants and flame retardant technologies after they are put into production in the future. In addition, Zhejiang Fenghong New Material Co., Ltd. is the largest refined clay producer in Asia and the third largest in the world. The research of this project will simultaneously promote the development of clay organic modification technology, enhance the competitiveness and international influence of enterprises, and broaden the application of clay in the field of polymers.

The greening of flame-retardant materials has increasingly become an important non-tariff barrier and technical barrier in international trade. The European Union has issued WEEE and ROHS directives, requiring all electronic and electrical equipment put on the EU market to meet the environmental protection standards required by the EU .

In order to protect the safety of people's lives and properties, our country made more stringent requirements on wall insulation materials in Document No. 65 issued in 2011. China is a big material country, and polymer materials occupy a very important position in the entire industry. Therefore, the development of green flame-retardant technology for polymer materials is a very critical topic.
