  • Patent number: 8343392
    Abstract: A composite material is constituted by fine nano-oxide particles, a dispersant, and a transparent resin material. The dispersant includes a polymer of vinyl monomer having a binding acidic group. When ? is a dimensionless number defined by an average particle size (nm) of the fine nano-oxide particles divided by nm, the polymer has a degree of polymerization of an integer of 3 or more and 8×? or less with the proviso that the integer is a numerical value obtained by dropping a decimal fraction. The composite material is produced through a step of obtaining a dispersant comprising a polymer by polymerizing a vinyl monomer having a binding acidic group in the presence of polyamine or in an aqueous dilute dispersion, and a step of mixing the dispersant, fine nano-oxide particles, and a transparent resin material.

  • Publication number: 20120329934
    Abstract: A composite material comprises aggregate and an elastomeric composition. The elastomeric composition comprises the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate component comprises a polymeric isocyanate, and optionally, an isocyanate-prepolymer. The isocyanate-reactive component comprises a hydrophobic polyol and a chain extender having at least two hydroxyl groups and a molecular weight of from about 62 to about 220. The chain extender is present in the isocyanate-reactive component in an amount of from about 1 to about 20 parts by weight based on 100 parts by weight of the isocyanate-reactive component. The aggregate may be rock, crumb rubber, and/or glass. The composite material has excellent physical properties and may be formed underwater, used in various locations, and used in various applications, such as for pavement, revetments, etc.
