The invention also discloses a preparation method of the polymer-based nanocomposite material for the earphone wire. The invention uses organically modified medical stone and chitosan to modify the water-based polyurethane, which has the properties of water resistance, aging resistance, yellowing resistance, stain resistance, abrasion resistance, antibacterial and radiation resistance, and is suitable for Applied to the outer coating material of the earphone wire to improve the overall performance.

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.
