摘要:
A method for making fire retardant material including fire retardant cellulosic insulation including an arrangement for adding one or m feedstocks and a fire retardancy chemical compound to a common blend tank prior to feedstock drying. The one or more feedstocks may include at least one virgin pulp stock feed and at least one recycled material stock feed. The amount and type of both the virgin feedstock and the recycled material feedstock is selectable. Old newsprint may be one type of recycled material feedstock. Another suitable type of recycled material feedstock is old corrugated containers. The method further includes retaining the fiber feedstock an the chemical compound together for enough time to ensure adherence or impregnations of enough of the chemical to the fibers after the drying process. Fluffing or fiberizing of the treated fibers may be accomplished under less severe conditions than ordinarily employed when making conventional cellulose insulation.

A composite flame barrier includes a woven or nonwoven fiber sheet material including flame resistant fibers of oxidized polyacrylonitrile; a mineral hydrate material at least partially embedded within the fiber sheet material. The fiber sheet material may be covered on one or two sides with an outer laminar material. The composite flame barrier is particularly useful in fire-rated wall assemblies, especially those designed to provide two, three and four hour fire-ratings, when tested according to ASTM E-119 or similar testing methods and standards.
摘要:
The present invention relates to the use of ionic liquids as flame retardants. The compounds of the invention may be used as flame retardants in various materials without causing damage to the environment and or health of humans or animals. Ionic liquid flame retardants maybe applied alone or in combination with traditional flame retardants. Ionic liquid flame retardants can be applied to finish textile, plastic, leather, paper, rubber or as wild fire flame retardants.
