Filling mother particle for spinning resin

A filling mother particle for spinning resin is made from spinnning resin (50-85%) which may be polyester, PET, polymide or polypropylene resin, clay (10-50%) which may be montmorillonite, kaolinite and powdered ore and has 0.01-2 microns of size, and disperser (1-6%) which may be amino acid or other through mixing, fusion and granulating, and features high dispersity easily being machined, wide frequency response and 85-90% of radiation rate.

Surface treatment agent of glass fiber for strengthening polyethelene terephthalate and its preparing method

The invented surface treatment agent is prepared by mixing bifunctional epoxy resin, emulgent, coupling agent, film former, and lubricant. Said surface treatment agent can improve the bonding property of the interface between polyethylene terephthalate (PET) and glass fibers to raise the tensile strength of the material, meanwhile it can also improve the shock resistance property of the material, because said surface treatment agent forms a definite thickness soft interface on the interface of glass fiber and PET engineering plastics.

Composite nanometer-level polyamide/graphite material and its preparation

The composite material is prepared by inserting amide monomer into between graphite layers before in-situ polymerization at 250-260 deg.C. Because graphite is sliced into homogeneously dispersed nanometer-level layers in polyamide plastics, the composite nanometer-level material has high conductivity and relatively lower graphite content while maintaining the excellent physical, mechanical and machining performance of polyamide plastics.
