Use | The product is a natural rubber, Chloroprene Rubber, Nitrile Rubber, styrene-butadiene rubber and butyl rubber and masticatory accelerator, as well as containing a high component of the synthetic rubber recycling agent. Suitable for high temperature mastication and low temperature mastication, sulfur can terminate its plastic decomposition. The toxicity of the product is small, no pollution, no smell, no effect on the physical properties and aging properties of the rubber. The product reacts with zinc sulfate solution to produce zinc pentachlorophenol, which can be used as a masticatory accelerator for natural rubber. It has significant promoting effect in high and low temperature use, and is suitable for open and internal mixers. Zinc pentachlorophenol has no effect on the physical properties, aging properties and chlorine flavor of vulcanized rubber, and can be used for light-colored products. This product is compounded with the true mineral material by nearly equal weight, and then a small amount of organic activator is added, that is, it is composed of pentachlorophenol compound, and can also be used as natural gum, cis-butyl gum, isoprene gum, |

use | this product is natural rubber, neoprene rubber, nitrile rubber, styrene butadiene rubber, butyl rubber and plasticizing accelerator, as well as regenerating agent of waste rubber with high synthetic rubber composition. Suitable for high temperature and low temperature plasticizing, sulfur can terminate its plasticolysis. The product has little toxicity, no pollution, no odor of vulcanized rubber, and no effect on the physical properties and aging properties of the rubber. The product reacts with zinc sulfate solution to produce zinc pentachlorothiophenol, which can be used as a plasticizing accelerator for natural rubber. It has a significant chemical promotion effect when used at high and low temperatures, and is suitable for open mills and internal mixers. Zinc pentachlorothiophenol has no effect on the physical properties, aging properties and chlorine taste of vulcanizates, and can be used in light-colored products. This product is compounded with mineral real materials by nearly equal weight, and then a small amount of organic activator is added to form a pentachlorothiophenol complex. It can also be used as natural rubber, butadiene rubber, isoprene rubber, styrene butadiene rubber, Nitrile rubber, neoprene rubber, butyl rubber and other rubber plasticizing agents containing unsaturated bonds can also have good plasticolysis at low temperatures. A small amount of sulfur has a termination effect on its plasmolysis. Used as rubber plasticizer |
Production method | It is obtained by the reaction of hexachlorobenzene and sodium hydrosulfide, using organic solvents such as dimethylformamide as the solvent. The pentachlorothiophenol produced by the reaction reacts with sodium hydrosulfide in the reaction system to produce sodium pentachlorothiophenol and hydrogen sulfide. Then, sodium pentachlorothiophenol is acidified with hydrochloric acid to precipitate pentachlorothiophenol, and then filtered, washed, and dried to obtain the finished pentachlorothiophenol. |
