preparation example Construction

[0026] The preparation method of the conductive fiber of the present invention is further characterized in that 5-20 wt% of the matrix fiber is added to the formula for configuring the conductive coating solution. This formula design of dissolving an appropriate amount of matrix fiber in the conductive coating liquid can increase the viscosity of the conductive coating liquid on the one hand, and can strengthen the bonding fastness between the coating layer and the matrix fiber on the other hand, which is better Improve the efficiency of surface dissolution-coating treatment.

[0027] The conductive fiber manufactured by the preparation method of the present invention has excellent electrical conductivity, and its volume specific resistance range can reach 10 0 Ω.cm~10 8 Ω.cm order of magnitude, and basically does not reduce its mechanical and physical properties, and at the same time feels soft, comfortable to wear when used in special clothing, and has excellent performance...

Embodiment 1

[0030] 1. Conductive component pretreatment. The conductive component is carbon black, which is pretreated by dry mixing method. Add carbon black into the high-mixer, stir at a high speed of 4000rpm for 10min, and heat up to 70°C. Spray the titanate coupling agent in the form of carbon black; first stir at a low speed of 1000rpm for 5 minutes, then stir at a high speed of 6000rpm for 10 minutes, and then the treated carbon black can be obtained.

[0031] 2. Configure the conductive coating solution, and configure the coating solution according to the following weight percentage formula:

[0032] Purified water 25%,

[0033] Formic acid 50%,

Abstract

The invention is related to a kind of electric fibre producing method and its product. The producing method comprises three steps: 1. adopt dry mixing method pretreats electric components that are anyone of carbon, metals, metallic oxides or latent electric high polymers; 2. compounding coating liquid according to the following weight percent: electric componets 20% - 50%, solvent 25% - 65%, pure water; the said solvent is one or two of formic acid, phenol, tetrachloride ethane, dimethyl acetamide, sodium hydroxide and H2SO4; 3. using coating method can produce the said electric fibre. Compared with the prior art, the present invention has such advantages as the electric components are uneasily to be desquamated, its conduction is permanent, its resistance rate is low, it has a soft handle sensing, it is comfortable to use, and so on. Its producing method is simple, and its costs are low.

Description

technical field [0001] The present invention relates to a preparation method of conductive fiber and its products, in particular to a preparation method of surface dissolution-coating type conductive fiber and the conductive fiber prepared by the method. The international patent main classification number is intended to be Int.cl 7 .D01F 1 / 00. Background technique [0002] With the development of high technology, the environmental pollution caused by electrostatic discharge is becoming more and more serious, and the consequences are not limited to comfort and aesthetics. In some cases, electrostatic discharge can cause many harmful results. For example, in the coal mining industry, static electricity may cause explosions, causing catastrophic accidents that cause casualties and property damage; Spectrum interference often causes modern electronic instruments and equipment used in electronics, communications, aviation, aerospace and other fields to have signal loss, bit erro...
