  • Patent number: 8246866
    Abstract: Composition protective against fire and use comprising: Water: 25-42% by weight; Ultramarine Blue: 0.015-0.025% by weight; Preservative: 0.09-0.15% by weight; Vegetable Binder: 1.6-2.7% by weight; Spanish White: 6-10% by weight; Calcium Carbonate: 33-56% by weight; Sulphate of Lime: 9-15% by weight, having a dual function, acting as a protective substance against fire as well as a fire-combating substance, such that as protective substance against fire, through application or spraying thereof on a surface to be protected, should it be reached by fire, it acts as protective barrier preventing fire from destroying or damaging it, while as fire-combating substance, through application or spraying thereof on a surface in flames, the fire is quenched and extinguished. The composition is breathable and absolutely wholly ecological, and consequently does not affect plant varieties, permitting the creation of totally effective firebreak “barriers”.

  • Patent number: 8246865
    Abstract: The flame retardant viscose is obtained by adding silica to the viscose and subsequently fixing the silica to the fiber, such that the final flame retardant fiber will have regenerated cellulose and a silica polymer providing the fibers with flame retardant properties. Conventionally, the regeneration of the viscose mixture is carried out using zinc sulphate, while the final phase of washing of the fiber is accomplished using sulphuric acid. Both zinc and sulphuric acid are highly contaminating products from the environmental point of view. The invention consists, on the one hand, of replacing the zinc sulphate with aluminum sulphate and, on the other, of replacing the sulphuric acid with hydrogen peroxide or oxygenated water, this minimizing the contaminating effect of the process to an extraordinary extent.

  • Patent number: 8246733
    Abstract: The present disclosure describes various building materials used in the building and construction industry, and to buildings or objects constructed therefrom, and to methods of making these building materials. The building materials comprise a polymeric material, such as sodium alginate and/or calcium alginate which confers significant flame-, fire- and heat-resistance or imperviousness to the materials. Other substances can be added to the materials to improve cross-linking and/or to produce resistance to fungal degradation. The building materials which can be produced, processed, or treated using the alginate polymers of the invention include, but are not limited to, wood products; masonry products; wall, roofing, flooring and siding products; and paint products. Further, sodium alginate in the form of a gel may be used as a firebreak to effectively stop the advance of grass fires, wildfires, and forest fires.

  • Patent number: 8133583
    Abstract: The present invention provides a fire retardant antiflux fiber, the fiber is composed of the following components: cellulose 60˜80% by mass, silicon fire retardant (calculated as silicon dioxide) 15˜36% by mass, tourmaline 0.1˜5%. The present invention also provides a process of producing fire retardant antiflux fiber, in the adding step, the silicon fire retardant is added into the cellulose xanthate in the xanthation step or the viscose which was prepared after the xanthation step, the level of adding the silicon fire retardant is 19˜30%, calculated as silicon dioxide. The fire retardant antiflux fiber of the present invention has high fire retardant antiflux effect, high fiber strength and excellent negative ion generating efficacy. At the same time, the viscose also maintains excellent filtering performance in the procedure using above production process, reducing the production standstill caused by the viscose blocking up filter screen, improving production efficiency.

  • Patent number: 8088310
    Abstract: Each year wildfires, forest fires and out of control camp fires do untold damage to millions of acres of land, while causing billions of dollars in damages to property, wild life, and human life. The Orr Formula is designed to aid in, and assist the extinguishment of such fires. The Orr Formula is a composition that comprises: 1) 10% by weight Calcium Phosphate which acts as a binder; 2) 10% by weight Corn Starch which aids in flaking of the remaining composition off the site to which the composition was applied after the fire has been extinguished and cooled; and 3) 80% by weight of a mixture of Sodium Silicate with a base exchange Silicate of Sodium Aluminum.
