Abstract

The invention discloses a method for preparing a silver-containing PET based composite resin material. In the method, a monomer of terephthalic acid (PTA) or dimethyl terephthalate (DMT) for synthesizing PET and a precursor silver glycol colloid solution are polymerized in situ to prepare the material. The PET / Ag composite resin material prepared by the method has high spinnability and antibacterial property, and the preparation method has smart concept, simple process, short preparation period and low production cost without pollution, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a composite material, in particular to a method for preparing a silver-containing PET-based composite resin material. Background technique [0002] Polyethylene terephthalate (PET) is a thermoplastic with the advantages of high rigidity and strength, creep resistance and good dimensional stability. It is widely used in fiber, film, packaging materials and other fields. In recent years, people have used inorganic nanoparticles to modify PET to prepare PET-based organic-inorganic nanocomposites with multifunctional uses to meet the needs of diversified functionalization. There are a large number of research reports at home and abroad, mainly to improve PET Mechanical properties, thermal properties, crystallization properties, etc. The reported studies on inorganic nanoparticles modified PET mainly include nano-montmorillonite, nano-calcium carbonate, nano-silicon dioxide, nano-titanium dioxide, and nano-zinc oxide. [0003] Nan...
