Non-porous thermoformable polyurethane solid

摘要

The subject disclosure presents systems and methods for manufacturing a non-porous thermoformable polyurethane solid by combining an uncured polyurethane resin with Aluminum Trihydrate (ATH), a plurality of particulates, molecular sieves, and color particulates. This combination is mixed in a vacuum for a time period sufficient to initiate an exothermic reaction within the mixture. After the time period, the exothermically reacting mixture is allowed to cure to form the polyurethane solid. The curing may occur in a mold, i.e. by pouring or injecting the mixture into the mold. Alternatively, the mixture may be sprayed on to a surface and allowed to cure.

主权项

1. A thermoformable, non-porous, polyurethane material, comprising:
a mixture comprising an isocyanate, a polyol, alumina trihydrate (ATH), and molecular sieves; wherein a temperature of an exothermic polymerization reaction of the mixture under vacuum is maintained at a maximum temperature at no greater than 10 degrees F. over an ambient temperature to prevent the mixture from boiling prior to being cured.
