15312 results about "Carbon black" patented technology

Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, or ethylene cracking tar. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content. However, carbon black is widely used as a model compound for diesel soot for diesel oxidation experiments. Carbon black is mainly used as a reinforcing filler in tires and other rubber products. In plastics, paints, and inks, carbon black is used as a color pigment.

Carbon nano tube electric conduction slurry and preparation method and application thereof

The invention discloses carbon nano tube electric conduction slurry and a preparation method and the application of the carbon nano tube electric conduction slurry. The carbon nano tube electric conduction slurry is composed of, by mass, 2% to 10% of electric conduction function body, 0.2% to 5% of dispersing agent and 85% to 97.8% of solvent. The electric conduction function body is spherical carbon nano tube groups or spherical carbon nano tube aggregates or the combination between the spherical carbon nano tube groups or the spherical carbon nano tube aggregates and one or more of carbon black, acetylene black, carbon fibers, conductive graphite and grapheme. The preparation method comprises the steps that the electric conduction function body and the dispersing agent are added into the solvent according to the percentage to be mixed, premix is obtained, the premix is ground in a grinding machine, and the electric conduction slurry containing a plurality of spherical carbon nano tube groups with the grain size ranging from 0.1 micron to 3 microns is formed. The carbon nano tube electric conduction slurry can be used as electric conduction agents of positive electrode and negative electrode materials of a lithium battery. According to the electric conduction slurry, an electric conduction network coating base materials is easily formed, the preparation technology is simple, production efficiency is high, and the obtained carbon nano tube slurry is good in stability and long in shelf life.

High-heat-conductivity rubber composite material and preparation method thereof

The invention discloses a high-heat-conductivity rubber composite material and a preparation method of the high-heat-conductivity rubber composite material. The high-heat-conductivity rubber composite material consists of the following ingredients in parts by mass: 100 of rubber, 4 to 6 of zinc oxide, 1 to 3 of stearic acid, 1 to 2 of anti-aging agents, 40 to 60 of carbon black, 1 to 1.5 of promoters, 1 to 3 of sulphur and 50 to 170 of heat conducting agents. The manufacture method comprises the following process steps that: the rubber is added into an open mill, the zinc oxide, the stearic acid, the anti-aging agents, the promoters, the carbon black and the heat conducting agents are sequentially added after the roll recovering, and finally, the sulphur is added. After rubber materials are uniformly mixed, the thin conduction is carried out, triangle bag packing and rolling are respectively carried out for five times, and the roll distance is regulated to 1.5mm for sheet output. The material sheets are placed into a mold, the vulcanization is carried out on a flat plate vulcanization machine, the vulcanization time is 15 to 20 minutes, the vulcanization temperature is 160 to 165 DEG C, and the vulcanization pressure is 10 to 12MPa. The material disclosed by the invention has an excellent physical and mechanical property and a high heat conduction factor.
