Patent number: 6635697Abstract: The present invention provides a flame-retardant which is not only excellent in flame-retarding property but also devoid of lowering moisture-resisting property specially in the course of molding of a resin so that the flame-retardant has little limitation for the molding method, the molding conditions and the intended use thereof. What is characterized is a flame-retardant comprising (a) an aliphatic amine salt of a phosphoric ester with 2-25 carbon atoms in the ester moiety thereof having a melting point of at least 100° C. but not more than a molding temperature of a thermoplastic resin and (b) a salt of phosphoric and/or polyphosphoric acid, the proportion of the component (a) to the component (b), i.e. (a)/(b) being 1/2-5/1 by weight ratio.Type: GrantFiled: January 24, 2001Date of Patent: October 21, 2003Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Tetsuo Kuwaki, Yasunobu Nakamura, Yasuhiro Muneuchi

Publication number: 20030139492Abstract: A moldable elastomeric intumescent material comprises chlorinated polyethylene, plasticizers, phosphate based foaming agents, char forming materials, antioxidants, intumescent materials, flame retardant materials, and graphite and/or expandable graphite. A curing agent, and optionally a co-curing agent or an accelerator, may further be incorporated into the material to improve the rigidity of the material when it is exposed to fire. The composition also possesses enhanced intumescence and flame retardancy properties by the addition of graphite, and preferably expandable graphite, to the composition.Type: ApplicationFiled: January 23, 2002Publication date: July 24, 2003Inventor: Ismat A.

Patent number: 6596202Abstract: Cellulosic materials such as wood chips, textile fibers and the like are treated to produce products such as particle board having enhanced fire and heat resistant properties. For example, wood chips are saturated with an eqimolar aqueous solution of monoammonium phosphate and diammonium phosphate. A metal hydroxide is added to the solution. The saturated wood chips are dried and mixed with a modified glue composition. The glue that which contains urea formaldehyde and/or phenolic resin is in powdered form and dissolved in water. The treated wood chips and modified glue is then mixed, formed into a mat and placed under pressure at about 120° C. for 8 to 15 minutes. The pressure may range from about 300 to 400 psi.Type: GrantFiled: December 18, 2000Date of Patent: July 22, 2003Assignee: Cool Dot Ltd.Inventor: Ghassan F. Afiouni
