Process for producing molded particulate articles utilizing a self-releasing binder based on a sulfonic acid modified isocyanate |
摘要 |
The present invention relates to a substantially anhydrous binder having a self-releasing effect for the production of pressed articles comprising: (A) a polyisocyanate; and (B) a sulfonic acid corresponding to the general formula: R-SO3H)n wherein n represents an integer of 1 or 2; R represents an aromatic hydrocarbon radical having from 6 to 14 carbon atoms, an aliphatic hydrocarbon radical having from 10 to 18 carbon atoms, a cycloaliphatic hydrocarbon radical having from 6 to 15 carbon atoms, an araliphatic hydrocarbon radical having from 7 to 15 carbon atoms or an alkaromatic hydrocarbon radical having from 7 to 24 carbon atoms; and the equivalent ratio of the components (A) and (B) is 100:0.5 to 100:20. The invention is also directed to the use of such binders in the production of shaped articles by the hot pressing of a wide variety of organic and/or inorganic materials.
