Embodiment 1

[0036]Example 1 Preparation of metal oxide particles 20 grams of zirconium oxychloride and 8 grams of ammonium hydroxide (ammonia water) were reacted between 60 ° C and 80 ° C, and the stirring speed and the concentration of the reactants were controlled to control the precipitation and agglomeration The particle size of the substance does not exceed 100 nanometers. The obtained product only needs to remove the ammonium salt according to a conventional method, and is directly used in the present invention without drying. The physical parameters of the obtained inorganic materials are shown in Table 1

Abstract

The invention provides a polyester and inorganic substance nano composite material and method for making it, wherein the particles of metallic oxide, inorganic non-metallic oxide or their composite oxides in nano scales is first pre-processed for reaction, then is placed in polymerization reaction device along with the intermediate of polytetramethylene terephthalate (PET) for blending, obtaining the nano composite material integrating inorganic substance and polyester base through chemical bonds dispersed in nano scales evenly.

Description

technical field [0001] The invention provides a polyester and inorganic nanocomposite material. Metal oxides, inorganic non-metallic oxides or their composite oxide nanoscale particles are pretreated and reacted with polyethylene terephthalate (PET) or polybutylene terephthalate (PBT) ) intermediates are co-mixed in the reactor to obtain a nanocomposite material in which inorganic substances are combined with the polyester matrix through chemical bonds and uniformly dispersed at the nanometer scale. [0002] The invention particularly relates to a preparation method of a polyester and inorganic nanocomposite material. Nanoscale particles of metal oxides, inorganic non-metal oxides or their composite oxides are dispersed in organic solvents, water solvents or composite solvents, and then react with the precursor reagent of another oxide added to obtain metal oxides. A nanocomposite system in which oxides, inorganic non-metallic oxides or their composite oxide nanoscale partic...
