  • Patent number: 10486970
    Abstract: A method for preparation of graft modified ammonium polyphosphate with ultra-low hydroplaning and resistance to hydrolysis belongs to the field of the preparation of flame retardant. Ammonia water is used as hydrolytic agent of amino silane. In the early stage of synthesis of ammonium polyphosphate with phosphorus pentoxide, diammonium hydrogen phosphate and melamine as raw materials, hydrolyzed amino silane ammonia mixture is added, and continues warming reaction, when the temperature drops to a certain temperature, melamine is added to maintain high temperature reaction for a certain period of time, then cools to obtain graft modified ammonium polyphosphate with ultra-low hydroplaning and resistance to hydrolysis. The present disclosure grafts ammonium polyphosphate with two kinds of amino grafting in stages, and the modified ammonium polyphosphate products after grafted basically have no hydroplaning when meets water.

  • Patent number: 10443153
    Abstract: The invention relates to molded cellulose bodies, in particular fibers, filaments, directly spun nonwovens, films, or foams which have flame-resistant properties. The fibers and filaments can be further processed as textiles into yarns, wovens, knitted fabrics, and nonwovens. The molded bodies are produced from solutions of cellulose and melamine cyanurate or cellulose and crosslinked or partially crosslinked melamine resin particles in an organic solvent. The melamine cyanurate or the melamine resin particles provide the molded cellulose bodies with flame-retardant properties. The molded cellulose bodies made of cellulose and melamine cyanurate or melamine resin particles can further contain flame retardants, in particular flame retardants which act synergistically, in a particulate form. The obtained textile fibers and nonwoven materials have a soft touch and can be processed or finished as filaments or yarns on conventional textile machines.

  • Patent number: 7429290
    Abstract: The present invention relates to a fire-resistant coating and method thereof, which confers enhanced flame and heat resistance to substrate such as building materials. The invented coating is especially applicable to cellulose-based building materials including but not limited to fiberboards, wallboards, roofing materials, particleboards, ceiling tiles, soundproofing boards and hardboards. This novel composition is also useful in providing a fire-resistant coating for concrete, metals, foamed polymeric materials, gypsum and other substrates. A preferred embodiment generally comprising: mono potassium phosphate, magnesium oxide, silica powder, calcium silicate, rice hull ash and water. A method for imparting fire-retardancy to substrates using the invented composition is also described.

  • Patent number: 7211293
    Abstract: A closed-loop system and process is used for applying fire retardant chemicals to fibers. 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.
