Abstract

The invention discloses tin antimony oxide dispersion liquid for improving the fiber conduction performance, a preparation method of the tin antimony oxide dispersion liquid and a preparation method of conductive regeneration cellulose fiber. The dispersion liquid is prepared by mixing ammonium polycarboxylate solution, soft water, ATO powder and sodium hexametaphosphate according to the weight ratio of (4 to 8):(2 to 6):(0.5 to 3):(0.1 to 0.5); the pH value of the dispersion liquid is 8 to 12. The dispersion liquid is added into prepared spinning viscose according to the addition quantity that the ATO powder in the dispersion liquid accounts for 3 to 10 weight percent of the methylcellulose in the spinning viscose; after the uniform mixing, the blending viscose raw liquid is obtained. Theblending viscose raw liquid is subjected to coagulating bath spinning shaping; then, refining and drying are performed to obtain the conduction regenerated cellulose fiber. The tin antimony oxide dispersion liquid is used for modified preparation of the conductive fiber; the addition quantity of the conductive powder is low; the conductive body and the cellulose are tightly combined; falling cannot easily occur in the subsequent use and processing process.

Description

technical field [0001] The invention relates to the technical field of modified cellulose fibers, in particular to a regenerated cellulose fiber with conductive modification properties. Background technique [0002] Antimony tin oxide (also known as nano antimony-doped tin dioxide, antimony tin oxide), English name ATO, is a new type of light-colored transparent conductive powder. It is using Sb +3 or Sb +5 (Antimony) doping instead of Sn +4 (Tin) Oxygen vacancies or electrons formed when forming a defect solid solution are used as carriers to conduct electricity, and its conductivity is not affected by environmental dryness and humidity, avoiding the shortcomings of organic antistatic agents that are dependent on the environment. Nano antimony tin oxide (ATO) has been widely used in the fields of gas sensor and antistatic due to its high sensitivity, light and transparent color, high temperature and corrosion resistance, good chemical stability, and non-toxicity.
