Recently, a new nano-ceramic flame-retardant functional masterbatch material developed by Jianxi New Materials Co.
, Ltd.
Technology Research Institute has completed the pilot test, and will build a new production line with an annual output of 5,000 tons
.
According to Li Yiwei, chairman of the company, the technology uses nano-ceramic materials, nano-glass beads, and aluminum hypophosphite to synergize, and cross-linking agents are used to pretreat the ceramic materials.
The functional groups containing polar R can interact with the carrier silicone rubber.
The organic groups of the side chains of the nanoparticle form chemical bonds, so that the nanoparticles are uniformly distributed in the multi-dimensional network structure and improve the dispersion effect
.
In addition, the technology also completes the chemical crosslinking and melting of the barrel through the continuous banbury extrusion process, and prepares high-concentration flame-retardant masterbatch materials with a mass fraction of 85% to 88%
Based on the development of tunnels, railways, urban railways, aviation and other industries, there is an urgent need for environmentally friendly rubber and plastic products with high flame retardancy and low smoke generation
.
The flame retardant system represented by halogen + antimony, phosphorus + nitrogen has the problem of high smoke generation, and the smoke toxicity is limited by the testing standard
To this end, the technical team of the Technology Research Institute of Jianxi New Materials Co.
, Ltd.
cooperated with McMaster University in Canada and the Hong Kong Polytechnic University to develop a nano-low temperature ceramic flame retardant function based on the carbon formation and temperature resistance of ceramic materials.
masterbatch
.
The flame-retardant masterbatch material can be efficiently flame-retardant, has the advantages of low smoke, halogen-free, high flame-retardant grade, and makes up for the deficiencies of other flame-retardant systems
