Definitions

  • the present invention relates to resinous powder fire retardant compositions and, more particularly, relates to powders whereby an aldehyde, an ammonium phosphate, a hydroxy reactant, a urea, reactant, an ammonium or alkaline earth metal compound, and phosphoric acid are sequentially reacted in selected proportions to yield a resinous powder composition providing unique fire retardant properties and/or characteristics when applied to various cellulosic, animal product and synthetic substrates and when incorporated into materials during their manufacture.

  • the product is a fine white solid powder which preferably will not pass through a +200 mesh screen. It is insoluble in hot and cold water and is not soluble in ordinary solvents.
  • the ratios given above should not deviate from the stated amount by more than 15 percent because the unique properties of the polymer may be affected, and to this extent, the ratios are critical. Further, the solid materials should be mixed together first, then added to the liquids which have been premixed in the sequence described herein.
  • the fire retardant powder of the present invention provides a number of advantages over fire retardants of the prior art, including those of my prior patents and applications discussed above. Thus, since it is a powder rather than an aqueous solution, shipping costs are lower because the solvent does not have to be shipped. Further, more fire retardant per pound is obtained. Further, airing is not required although the composition may have to be dried, either by air drying or by application of heat. Further, the powder resin does not stiffen or weaken fibers.
  • the powder may be applied to paper, wood, plastic, or other substrates, or mixed with other compositions, such as paints. It may be colored with a pigment or dye and may be mixed with i ⁇ 2 or carbon black. It may also be mixed with other fillers. An especially important advantage is that the powder does not leave residual formaldehyde odors on the treated substrates.
  • the powder is used by mixing with water to form a suspension. Any desired concentration may be used, e.g., from 5 to 50 parts of powder per 100 parts of water. To impregnate fabrics, about 10 to 15 parts of powder in 100 parts of water is preferred.
  • the powder may be used to coat wood and plastic substrates where a binder is included in the composition. Suitable binders include lacquers and acrylic resins. When using a binder of this type, the binder is the carrier so that water is not necessary.
  • the powder is usually mixed with about 5 to 50 parts of binder.
  • the powder can also be incorporated into fibers and plastic systems, such as po lyur e thane , to provide fire retardant properties in situ.
  • ammonium phosphate, ammonium or alkaline metal compound, and urea reactant are used in the solid form which is available commercially. Equivalent materials may, of course, be used provided the same results are achieved.
  • the phosphoric acid is preferably added as an 85 percent aqueous solution, as this form is commercially available.
  • the urea reactant is selected from the group comprising of urea, substituted ureas and cyclized ureas, including but not limited to urea, thiourea, ethylene urea, dimethylol ethylene urea, melamine, or other substituted urea, including mixtures. Urea is preferred.

However, the sample regained 4 percent of this weight loss after exposure to the air for 48 hours. The weight loss may, therefore, be attributed to moisture.
