Abstract
Inorganic or organic particles or fibers are bonded together with an organic polyisocyanate containing ionic groups to form a composite material for filling cracks, joints or the like or for making panels or other products used in the building industry.
Claims15
A process for the production of a composite material which comprises:
- A. mixing
- i. from 1-90 percent by weight of an organic polyisocyanate which contains 2-200 milliequivalents of ionic groups or groups which are capable of forming ionic groups in the presence of alkaline or organic basic compounds, per 100 grams of polyisocyanate,
- ii. from 10-99 percent by weight of an organic or inorganic particulate or fibrous material, and
- B. allowing the resultant mixture to react.
As a new article of manufacture, a shaped product comprising particles or fibers bonded together by a reaction product of an organic polyisocyanate containing 2-200 milliequivalents of ionic groups or groups capable of forming ionic groups in the presence of alkaline or organic basic compounds per 100 grams of polyisocyanate.
