The system of polyisocyanurate traction extrusion process for the preparation of a polymeric composite reinforced fiber of polyisocyanurate cured, and the product of polyisocyanurate

摘要

"The process of extrusion traction for the preparation of a composite reinforced by fibers cured system of reaction for the preparation of a composite reinforced by fibers, and,The product of composite solid ".The invention relates to a polyisocyanurate systems, extrusion traction of those systems to produce composite matrix reinforced polyisocyanurate.And the composites produced from the same. The polyisocyanurate systems include a polyol component, an optional chain extender, and an isocyanate.The polyisocyanurate systems have a long time of initiation, about 5 minutes to about 30 minutes at room temperature and can be easily cured.
