  • Patent number: 9382401
    Abstract: The problem to be solved is to provide a nondrying polymer hydrogel, which is not dried under atmospheric conditions and has excellent mechanical properties, and a method for producing the nondrying polymer hydrogel. A nondrying polymer hydrogel having both excellent nondrying properties and mechanical properties (e.g., excellent elongation properties, compression properties, and surface adhesiveness) can be produced by using a nondrying polymer hydrogel including a deliquescent substance in such a manner that the water vapor pressure shown by the polymer hydrogel is equal to or lower than the water vapor partial pressure in the atmosphere, in particular, by allowing a deliquescent substance to be contained at a high concentration in a polymer hydrogel having a network structure formed by a polymer of a water-soluble radically-polymerizable organic monomer having a specific chemical composition and a delaminated water-swellable clay mineral.

  • Patent number: 9328216
    Abstract: The present invention relates to improved clayey barriers, such as compacted clay liners or geosynthetic clay liners, which can be used, among other uses, to isolate waste liquids from the environment. More in particular, the present invention relates to clay which is treated with an anionic polymer and is subsequently dehydrated before it is used as a barrier. The latter improved clays are surprisingly well, and for a long term, protected from chemical attack by aggressive electrolyte solutions present in, for example, sea water or waste liquids.

  • Publication number: 20120146297
    Abstract: The present invention refers to a textile formed by fiberglass impregnated with a water base elastomeric mixture, to substitute the aromatic base solvent elastomeric mixture and other types (acetates, ketones, alcohols, aliphatics, gas solvents, chlorates, glycoethers and mixtures such as Thinner Standard) used in the entire world and by doing so, offer a non-contaminating product to both the environment as well as to humans, given that it can cause brain, movement, cognitive, and learning problems through the inhalation of the solvent in the environment as it acts as a VOC contaminant given the high carbon content and the evaporation at room temperature which the solvent exhibits.

  • Patent number: 8168698
    Abstract: A method for producing random form of nanosilicate platelets comprises mixing and acidifying an exfoliating agent with an inorganic acid to form an acidified exfoliating agent; intercalating layered inorganic silicate clay with the acidified exfoliating agent to form a mixture; and dissolving the mixture in a solvent and reacting it with a hydroxide or chloride of alkali metal or alkaline-earth metal. The hyperbranched polyamines serving as the exfoliating agent are prepared by polymerizing poly(oxypropylene)-triamine and diglycidyl ether of bisphenol-A (DGEBA). Hydrophilic amine groups of the exfoliating agent are acidified and then reacted with the layered inorganic silicate clay through cation exchange reaction and physical clay exfoliation to give random form of nanosilicate platelets.

  • Publication number: 20110272641
    Abstract: A method of incorporating an additive into a polymer composition includes the step of melt blending a polymer with a dispersion comprising a liquid carrier, an unmodified clay, and an additive. Using the dispersion rather than a polymer-based additive masterbatch saves energy. Like a polymer-based masterbatch, the dispersion provides the additive in a diluted form and therefore preserves the masterbatch's advantages of providing more uniform distribution additive in the plastic and avoiding direct handling of additives in the final compounding step. The dispersion is also described.
