Abstract

The invention discloses a production process of antibacterial fat cotton, wherein the antibacterial fat cotton comprises a polyurethane group, polyether, ethylene glycol, silicone oil, phenol, dichloromethane, a polysiloxane copolymer, a nano zinc oxide antibacterial particle group and chitosan quaternary ammonium salt, and the nano zinc oxide antibacterial particle group comprises more than 90% by mass of nano-zinc oxide. The process comprises: heating ethylene glycol to 185-190 DEG C, adding nano zinc oxide antibacterial particle group, fully and uniformly stirring, cooling to 80-95 DEG C, adding chitosan quaternary ammonium salt, and fully and uniformly stirring to obtain an antibacterial mixed group; and putting into a foaming reaction kettle for foaming reaction to obtain the antibacterial fat cotton. According to the invention, the dispersion requirement of nano antibacterial particles in the fat cotton can be met through the antibacterial mixing group, so that the subsequent foaming distribution uniformity is better, and the antibacterial fat cotton has very excellent antibacterial and bacteriostatic effects; and the foaming process is participated by adopting staged investment, so that the effective distribution uniformity of an antibacterial mixed group is improved while the porosity requirement is met, and the antibacterial and bacteriostatic effective time of the fat cotton is prolonged.

Description

technical field [0001] The invention relates to a production process of antibacterial fat cotton, and belongs to the technical field of antibacterial sponge materials. Background technique [0002] Apparel linings include cups, elastic gaskets, joint surrounds, etc., which need to provide relatively reliable elastic support, and must also meet the performance of water resistance and anti-discoloration. [0003] Traditional clothing linings are made of TDI and other materials through foaming process, but TDI and other materials have poor oxidation resistance, and anti-yellowing agents need to be added during the production process. Generally, phenol is used as an anti-yellowing agent, which will produce yellowing when it meets water. Irritant odor and irritating substances will remain in the foam sponge. In addition, the elastic recovery of the foam sponge made of TDI and other materials is insufficient, and there will be deformation after long-term use, which will affect the...
