  • Patent number: 10968355
    Abstract: We have demonstrated reversibly reducing metal-ion crosslinkages in polymer systems, by harnessing light, creating a dynamic and reversible bond. The reduction induces chemical and physical changes in the polymer materials. Some variations provide a polymer composition comprising: a polymer matrix containing one or more ionic species; one or more photosensitizers; and one or more metal ions capable of reversibly changing from a first oxidation state to a second oxidation state when in the presence of the photosensitizers and light. Some embodiments employ urethane-based ionomers capable of changing their crosslinked state under the influence of a change in counterion valance, using light or chemical reducing agents. This invention provides films, coatings, or objects that are reversible, re-mendable, self-healing, mechanically adjustable, and/or thermoplastic/thermoset-switchable.

  • Patent number: 10745510
    Abstract: The present invention discloses a phosphorylated polycondensate high-performance water-reducing agent with a phosphorylated melamine derivative, instead of a conventional carboxyl group or sulfonic group, as a main adsorption group. The use of aryl alkoxypolyether as a side chain of the polymer provides a strong steric effect to improve the dispersibility and dispersion-retaining properties of the polymer. A polycondensate high-performance water-reducing agent and a method for preparing the same provided by the present invention have excellent overall performance, high adaptability for current low-grade raw materials of concrete, strong market demands, and vast application prospects. Additionally, the polycondensate has an advanced preparation process provided with the characteristics of industrially scalable production, which offers the prospect of a core technology in the field of water-reducing agent of concrete so as to promote development of the industry.

  • Publication number: 20130345340
    Abstract: The present invention relates to compositions which are suitable for optimizing mineral building material compositions so that the flow behaviour and the deaeration of the compositions is positively influenced, as a result of which very smooth, virtually pore-free surfaces can be achieved. The compositions can consist of a mixture or comprise a mixture which contains at least one component (a) which comprises a compound N which displays a wetting action in aqueous cement-containing binder systems and contains at least one further component (b) which comprises a compound E which has antifoam properties in aqueous cement-containing binder systems. The compound N in component a) can preferably be a nonionic or amphoteric surfactant, preferably an alkyl alkoxylate or a betaine. The compound E in component b) can preferably be a polyetherpolysiloxane on a support material.

  • Publication number: 20130330532
    Abstract: The subject of the present invention is a gypsum containing aqueous slurry containing a phosphate based polycondensate as sole agent with dispersing properties. With a phosphated polycondensate according to the invention as sole dispersing component an improved efficiency was found in comparison with the polycondensates known in the prior art. As additional favorable effect a significantly decreased retardation of the setting and hardening of the various construction compositions and especially of gypsum based slurries compared to other dispersants is to be observed, independently from the dosage of the dispersing component. This effect of the polycondensate component as well as an expedient influence on the pore structure surprisingly can be observed.

  • Publication number: 20130231415
    Abstract: The invention relates to copolymers effective as slump retention agents for hydraulic compositions such as cement, mortar and concrete. The copolymers are formed by reacting monomers A, B and C, wherein monomer A is a compound of formula I, monomer B is a compound of formula II, and monomer C is a compound of formula III or IV as shown herein. The copolymers may be used alone or in combination with a water reducing agent or slump retaining agent, e.g. a superplasticizer such as PNS or PMS or a low range water reducer such as lignosulfonate. The copolymer includes a group that is hydrolyzable at elevated pH (e.g. around pH 12) typically present in hydraulic compositions, so that the group hydrolyzes when present in such compositions and forms a charged group that provides extended slump retention properties without introducing undesirable air-entraining characteristics.

  • Publication number: 20130146286
    Abstract: A self-adaptive cement formulation includes cement, water and thermoplastic block-polymer particles. The set cement demonstrates self-healing properties when exposed to methane, and is particularly suited for well-cementing applications. After placement and curing, the self healing properties help maintain zonal isolation should bonding be disrupted between the set cement and the formation or a casing string, should cracks or defects appear in the set-cement matrix, or both.
