  • Patent number: 8814998
    Abstract: The present invention teaches a three-step method for an aqua based chemical composition for flame retardation. The composition comprises: Sodium Borate, Boric Acid, Guanylurea Phosphate, Hydrogen Peroxide, Magnesium Chloride, and Sodium Silicate. The referenced salts are dissolved in distilled water, and the resultant flame retarding solution is coated on substrate surfaces to be protected against flame retardation. The flame retarding composition solution from step-1 alone may be used on non-prepared substrate surfaces. The flame retarding composition solution fully satisfies the Federal Aviation Regulation (FAR) 25.853(a) vertical burn test, and Federal Aviation Regulation (FAR) 25.853(d) heat release test. The utility of the present invention extends to numerous commercial and non-commercial applications.

Furthermore, zinc pyrithione used as an antifouling agent for ship-bottom paints is eluted from a coating film at a high rate and thus results in poor long-term antifouling effect, so that it is also required to devise a way to decrease the solubility thereof in seawater. These problems could be solved at once by an antibiotic composition obtained by adsorbing zinc pyrithione or a zinc pyrithione/zinc oxide composite compound to hydrous titanium oxide.

Fibers are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. Recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.

  • Patent number: 6517748
    Abstract: A phosphate and ammonia free composition for treating an object (i.e., lumber, plywood and other wood products) is described. The treating solution may be applied to the object by dipping, soaking, brushing, spraying, etc., however, vacuum and/or pressure techniques may be used to impregnate the object according to the method of this invention, including both the empty-cell process and the full-cell process. The composition achieves fire retardant qualities without object degradation when the treated object is subjected to heat and humidity over time. The composition of this invention includes nitrogen in a predetermined ratio to boron.

  • Patent number: 6387300
    Abstract: A method for producing products for treating wood and other cellulose products to improve the flame retardancy, and the insecticidal and fungicidal properties of the products. A calcium borate ore, such as colemanite, is reacted first with an acid such as acetic acid. The reaction products, including calcium in solution, are then treated with ammonia, producing ammonium pentaborate. The resulting composition is applied to the wood or other cellulose products by methods such as pressure, diffusion, or immersion and/or dipping treatment. The products have superior leach resistance to water when compared to conventional treatment compounds.
