    摘要: The present invention relates to a polyurea system, the use of such a polyurea system for sealing, linking, gluing, or covering of cellular tissue, and a dosing system having two chambers for a polyurea system such as this. The polyurea system comprises as components: A) an isocyanate-functioning prepolymer, which can be derived by reacting aliphatic isocyanates with polyoles, and B) an amino-functioning ester of aspartic acid. According to the invention, water and/or tertiary amine is added to the system, in order to increase the reacting speed of the prepolymer with the amino-functioning ester of aspartic acid while decreasing the setting time at the same time.

    摘要: The present invention relates to a reaction system for preparing polyurethane microcellular foam, a polyurethane microcellular foam and the use thereof. The reaction system for preparing polyurethane microcellular foam comprises isocyanate prepolymer, polyols, catalysts and chain extenders. The isocyanate prepolymer is a reaction product of polyisocyanates and polyester polyols, wherein the polyester polyols comprise 10-60 wt. % succinic acid units, based on 100 wt. % of the polyester polyols, the NCO content of the isocyanate prepolymer is 13-30 wt. %, based on 100 wt. % of isocyanate prepolymer. By using the reaction components provided in the present invention, the demould time for preparing the polyurethane microcellular foam can be reduced. The obtained polyurethane microcellular foam, which possesses good physical and mechanical properties, is particularly suitable to prepare shoes.
