Polymer-based nano-composite material for headset wire and preparation method of polymer-based nano-composite material

Abstract

The invention discloses a polymer-based nano-composite material for a headset wire. The polymer-based nano-composite material is prepared from the following components in parts by weight: 20-30 parts of aqueous polyurethane nano-composite emulsion, 30-40 parts of an oil plasticizer, 6-10 parts of sodium stearate and 10-20 parts of calcium carbonate, wherein the aqueous polyurethane nano-composite emulsion contains organic modified medical stone dispersion liquid, a polymer dihydric alcohol, an HDI tripolymer, water-soluble chitosan, a catalyst dibutyltin dilaurate, trimethylolpropane, an antioxidant 1010, triethylamine, deionized water and ethanediamine in a mass ratio of 0.05:2.8:1.2:2.3:0.03:0.3:0.015:0.2:10:0.04. The invention further discloses a preparation method of the polymer-based nano-composite material for the headset wire. As organic modified medical stone and deacetylation chitosan are adopted to modify aqueous polyurethane, the polymer-based nano-composite material has the properties such as water resistance, aging resistance, yellowing resistance, contamination resistance, wearing resistance, bacterium resistance and radiation resistance, and is applicable to a coating material of the head set wire, and the comprehensive property of the headset wire can be improved.

Description

technical field [0001] The invention relates to the field of nanocomposite materials, in particular to a polymer-based nanocomposite material for earphone wires and a preparation method thereof. Background technique [0002] The polymer-based composite material not only maintains various excellent properties of the polymer matrix itself, but also can give full play to the specific performance of the nano-units, and can also inhibit the oxidation and aggregation of the nano-units, so that the system has high long-term stability. Nano-modified waterborne polyurethane materials overcome the defects of waterborne polyurethane water resistance and weather resistance, improve the material's water resistance, aging resistance, stain resistance, thermal stability and wear resistance, and can also make waterborne polyurethane antibacterial and radiation resistant , deodorant and other properties. [0003] Medical stone is a compound mineral or medicinal rock that is non-toxic and ha...

Problems solved by technology

[0004] Existing polymer-based nanocomposites and their preparation methods often have extremely high surface energy and a strong tendency to agglomerate due to the high surface energy of inorganic nanoparticles. It is originally a dispersed equilibrium state, and what is often obtained is that the nanoparticles are agglomerated into composite materials with a scale of hundreds of nanometers or even micrometers, thus losing the unique functions and effects of nanoparticles.
