Process of recycling a fiber-reinforced polymeric material and related apparatus

摘要

The present invention is related to a process of recycling fiber-reinforced polymeric material including the following steps: a) crushing the material so as to reduce it into fragments; b) mixing the material obtained in the previous step with a liquid adhesive; c) pouring the mixture obtained in step b) into a mold; d) applying a pressure. In particular, the mixing step b) is carried out by nebulizing some adhesive and simultaneously stirring the particles of the fiber-reinforced polymeric material so that a thin layer of adhesive will deposit on the surface of basically each particle of the fiber-reinforced polymeric material. Furthermore, the present invention relates to an apparatus for carrying out the process.

1. Process of recycling a fiber-reinforced polymeric material comprising the following steps
a) crushing said material so as to reduce it into fragments; b) mixing the material obtained in the previous step with a liquid adhesive, said step b) being carried out by nebulizing said adhesive and simultaneously stirring the particles of the fiber-reinforced polymeric material so that a thin layer of adhesive is deposited on the surface substantially of each particle of fiber-reinforced polymeric material; c) pouring the mixture obtained in step b) into a mold; d) applying a pressure, following said first step a), it is provided a step a′) of grinding at least a portion of the fragments obtained in said step a) so as to obtain granules of dimensions between 2 and 8 mm, and subsequent to said step a′), it is provided a step a″) of pulverizing at least a portion of the granules obtained in step a′) so as to obtain particles of dimensions smaller than 1 mm.
