  • Patent number: 9181130
    Abstract: Redispersible polymer powder compositions which include a polyglycol in admixture with a redispersible polymer powder (RDP), which powder includes a codried mixture of a carboxylated, water insoluble film-forming styrene butadiene polymer and a colloidal stabilizer, results in cement compositions having unexpectedly superior overall bonding strength and adhesion after water immersion. Use of the polyglycol provides good workability or ease of troweling during application. In addition, the RDP composition, which includes the RDP and the polyglycol, provides the cement-based composition with excellent abrasion resistance, surface appearance, and color. Also, the RDP composition provides for at least a 30% reduction, for example a 50% or more reduction in the amount of retarder or retardant employed in the dry mix formulation for cement compositions, such as self leveling flooring compounds or compositions, and cement-based tile adhesives.

  • Patent number: 9006314
    Abstract: Use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of thermoset polymer particles is disclosed. One method is the application of post-polymerization process steps (and especially heat treatment) to advance the curing reaction and to thus obtain a more densely crosslinked polymer network. The other method is the incorporation of nanofillers, resulting in a heterogeneous “nanocomposite” morphology. Nanofiller incorporation and post-polymerization heat treatment can also be combined to obtain the benefits of both methods simultaneously. The present invention relates to the development of thermoset nanocomposite particles.

  • Patent number: 8716370
    Abstract: A roof sloping compound for creating an auxiliary slope over a wide variety of roof membranes and substrates. The compound includes a dry mixture of aggregate, cement and a redispersible dry polymer adapted to be mixed with water to define a substantially self-leveling consistency enabling the compound to be readily screeded into place in a desired thickness. The aggregate comprises dolomite or limestone and the redispersible dry polymer can comprise a binder based on a copolymer of ethylene vinyl acetate. In a lightweight embodiment of the compound, the aggregate includes lightweight fillers comprising perlite and low density glass granules and a superplasticizer is added to the dry mixture to reduce water demand.

    Abstract: A flame retardant composition is produced by mixing a flammable organic material with an inorganic phosphorus-inorganic phosphoric oxyacid compound or its salts. The inorganic phosphorus-inorganic phosphoric oxyacid compounds are produced by reacting an inorganic phosphorus compound having a valence of 3-4 with an inorganic phosphorus oxyacid with a valence of 5. Carbonization auxiliaries, metal-containing compound having a carbonization acceleration effect, a comb-like polymer and a filler may be added with the flame retardant composition.

  • Publication number: 20140060388
    Abstract: Ultra-high-performance cementitious materials are made using suitably functionalized and relatively low-cost carbon nanofibers and graphite platelets. Polyelectrolytes and surfactants are physisorbed upon these graphite nanomaterials in water, and dispersion of nanomaterials in water is achieved by stirring. Stable and well-dispersed suspensions of nanomaterials in water are realized without using energy-intensive and costly methods, and also without the use of materials which could hinder the hydration and strength development of ultra-high-performance cementitious materials. The water incorporating dispersed nanomaterials is then mixed with the cementitious matrix and, optionally, microfibers, and cured following standard concrete mixing and curing practices. The resulting cementitious materials incorporating graphite nanomaterials and optionally microfibers offer a desired balance of strength, toughness, abrasion resistance, moisture barrier attributes, durability and fire resistance.
