Devastating residential blazes and wildfires take a terrible toll in terms of deaths and injuries, as well as property loss. Today, researchers will report on a new type of coating that could limit the flammability of wood used in construction, potentially providing more time to escape fires and also curbing their spread. The environmentally friendly flame retardant could also be used for other flammable materials, such as textiles, polyurethane foam and 3-D-printed parts.
for these materials."This type of treatment, which could be deposited via dipping, spraying or pressure treatment, could make homes much safer," he says."The coating could reduce flame spread and smoke production, which could limit damage and give people more time to evacuate." Unlike most current fire retardant treatments, its ingredients are environmentally benign, and it might also cost less, notes Jaime Grunlan, Ph.D., the project's principal investigator.
Kolibaba wanted to extend this treatment to wood, but the multistep process wasn't feasible for manufacturers because wood takes too long to soak up these chemicals. Through further research he adapted another Grunlan technique, thereby cutting the number of steps down to two: one dip to coat the wood, followed by a dip in a different solution to cure the coating by changing the pH.
