Принадлежит: GWANGJU INSTITUTE OF SCIENCE AND TECHNOLOGY

The present invention relates to a porous polyurea material and a method for preparing the same. The porous polyurea material may be prepared by polymerization and crosslinking of tetra(4-aminophenyl)methane with a monomer two to four isocyanate (—NCO) groups. The method includes: mixing an organic solution of tetra(4-aminophenyl)methane with an organic solution of a monomer having two to four isocyanate groups; reacting the mixed solution under a nitrogen atmosphere; and drying a semi-solid or solid material formed by gelation of the reaction solution, or adding the reaction solution to a non-solvent before gelation of the reaction solution to form a precipitate, followed by drying, or applying the reaction solution to a substrate before gelation of the reaction solution, followed by drying. According to the present invention, the introduction of the monomer having a tetrahedral structure can impart good chemical resistance, heat resistance and durability to the porous polyurea material.

(canceled)15. (canceled) The present invention relates to compositions for the preparation of a polymeric foam with improved thermal properties, and to a foamed polymeric article obtainable therefrom, and to a method for preparing such a polymeric foam or article.In response to environmental concerns, there has been an evolution from using hydrochlorofluorocarbon (HCFC) foam blowing agents to using carbon dioxide and/or hydrocarbons and alcohols. Unfortunately, as a result of this change, the thermal conductivity of foam materials has increased due to the higher conductivity of these new blowing agents. This results in insulation foams that no longer fulfill the required product specifications unless additional steps are taken to increase the thermal resistance of these insulation foams.It is known that an infrared attenuation agent (IAA) can be used to improve an insulation foam. An effective infrared attenuation agent favors increased reflection and absorption and decreased transmission of heat radiation as much as possible. Traditionally, inorganic materials have been used as IAA to reduce the portion of heat radiation. This includes, for example, graphite, aluminum, stainless steel, cobalt, nickel, carbon black, and titanium dioxide. As an example for several ...
