Dallin L. Smith, Kathleen Floyd, Margaret J. Karim, James Batteas, Jaime C. Grunlan
TL;DR
Vibratory ball milling makes a flame-retardant material more effective by reducing its particle size, allowing it to be used in polymer emulsions.
Contribution
A new method using vibratory ball milling to enhance the performance of solid polyelectrolyte complexes as flame-retardant additives.
Findings
Vibratory ball milling reduces the particle size of the polyelectrolyte complex by an order of magnitude.
The processed material achieves self-extinguishing behavior and a V-0 rating in UL 94 flame testing.
Abstract
Vibratory ball milling reduces the particle size of a polyallylamine, poly(sodium phosphate) containing polyelectrolyte complex (PEC) by an order of magnitude for use as a flame‐retardant additive in a polymer emulsion to achieve self‐extinguishing behavior and a V‐0 rating with UL 94 flame testing. This demonstrates a new approach for using solid PECs as flame‐retardant additives. Vibratory ball milling reduces the particle size of a solid polyelectrolyte complex (PEC) by an order of magnitude, enabling its use as a flame‐retardant additive in a polymer emulsion to achieve self‐extinguishing behavior. This work demonstrates a new approach for using solid PECs as flame‐retardant additives.
