Abstract

The invention relates to an aqueous sizing composition for reinforcing charges, preferably glass fibers, comprising a silane coupling agent, an epoxy film forming polymer comprising 2-8 reactive epoxy groups per chain and compatible with thermoplastic polyester matrix resin selected from PET and PBT, and a hypophosphite in an amount of 5 to 30 w% of the composition, preferably 7 to 25 w%, more preferably 10 to 20 w% and most preferably 12 to 18 w% of the composition. A thermoplastic polyester resin reinforced with glass fibers coated with a sizing composition of the invention shows improved resistance to staining and improved tensile elongation at break. The sizing composition further improves processability of the sized fibres.

Description

Background of the invention [0001] The present invention relates to a sizing composition for a reinforcing material or feed intended for use as a polymeric matrix material (more specifically a thermoplastic polymeric material such as a thermoplastic polyester material, more specifically a polymeric Polyethylene phthalates, such as polyethylene terephthalate (PET) or polybutylene terephthalate (PBT)), particulate feed for reinforcements, including glass or sand, natural fibers such as bamboo fibers) or mineral fibers (more specifically basalt, carbon or glass fibres). The present invention further relates to reinforcement materials, more specifically mineral fibers (preferably glass fibers) treated with the sizing composition of the present invention , and with respect to thermoplastic polymeric materials (such as polyester materials, more specifically polyethylene terephthalate, such as polyethylene terephthalate, such as polyethylene terephthalate) reinforced with these feeds...
