AI Technical Summary

Technical Problem

Conventional flame retardants for polymer materials, such as antimony trioxide, are costly, affect mechanical properties, and cause color inconsistency, limiting their application in industries like military, aerospace, and transportation.

Method used

A highly dispersed flame retardant masterbatch comprising a composite of antimony trioxide, borate, and an organophosphorus-nitrogen complex, with additives like polycaprolactone-modified nanocalcium carbonate, liquid calcium zinc stabilizer, and metal soap-based lubricants, enhances dispersibility and thermal stability while maintaining mechanical properties.

Benefits of technology

The composite flame retardant system provides superior fire resistance, improved dispersibility, thermal stability, and reduced mechanical property degradation, enabling broader industrial application of polymer materials.

Abstract

The objective is to provide a highly dispersed flame-retardant masterbatch and a method for manufacturing the same. [Solution] The present invention belongs to the field of polymer materials and relates to a highly dispersed flame retardant masterbatch and a method for producing the same. The highly dispersed flame retardant masterbatch comprises, by weight, 8 to 30 parts by weight of a polymer, 30 to 95 parts by weight of a composite flame retardant containing antimony trioxide, borate, and an organophosphorus-nitrogen complex, 6 to 20 parts by weight of a plasticizer, and 0.1 to 15 parts by weight of an auxiliary agent, wherein the organophosphorus-nitrogen complex is one or more of a mixture of DOPO and MCA, polyphosphate melamine, and ammonium polyphosphate. The present invention significantly improves the flame retardant performance of the material by optimizing the recipe of the flame retardant.
