Abstract

The invention relates to environment-friendly water-based conductive black slurry for coatings and a preparation method thereof, and belongs to a coloring agent special for the printing and dyeing industry. The environment-friendly water-based conductive black slurry for the coatings is prepared from the following raw materials in part by weight: 20 to 50 parts of water, 30 to 45 parts of carbon black, 2 to 6 parts of dispersing agent, 1 to 5 parts of emulsifying agent, 1 to 5 parts of ammonium salt aid, 10 to 20 parts of water-based intermediate and 4 to 15 parts of diethylene glycol. The environment-friendly water-based conductive black slurry has the advantages of reasonable formula design, good coloring effect, excellent conductivity and low manufacturing cost.

Description

technical field [0001] The invention relates to an environment-friendly water-based conductive black paste for coatings and a preparation method thereof, which belongs to a special colorant in the printing and dyeing industry and is widely used in oil fields, petrochemical, chemical, electrical and electric power, military and police combat uniforms, racing uniforms, and firefighting combat uniforms Coloring of clothing that has special requirements for clothing performance, such as aviation clothing. Background technique [0002] The antistatic processing methods of fabrics usually include: 1. The fabric is finished with an antistatic finishing agent; 2. Fiber grafting modification for the purpose of improving the hygroscopicity of the fabric, blending and interweaving of hydrophilic fibers; 3. Blending or Embedding conductive fibers; The mechanism of action of the first two types of methods is to increase the moisture regain of the fabric, reduce the insulation, and accele...
