Guangzhou shelf rubber vulcanization accelerator D

 Accelerant D English name: accelerator D Chinese alias: diphenyl guanidine; accelerator DPG; rubber vulcanization accelerator DPG; 1,3- diphenyl guanidine; N, N'- diphenyl guanidine; symmetrical diphenyl guanidine; rubber accelerator agent D English Name: diphenyl guanidine; melaniline; accelerator DPG CAS ??? No.: 102-06-7 Molecular formula: C13H13N3 Molecular Weight: 211.26 Molecular Structure: Properties: 1. white powder, bitter taste, there is a faint odor; 2. The relative density of 1.13 ~ 1.19. Melting point 147 ℃, more than 170 ℃ begins to decompose; 3. soluble in benzene, toluene, chloroform, ethanol, acetone, ethyl acetate, soluble inorganic acid, slightly soluble in water, its solution is strongly alkaline. Applications: 1. accelerator D is mainly used for natural rubber and synthetic rubber speed accelerator. Often used as thiazoles, thiuram and sulfenamide accelerator active agent. When combined with accelerator DM, TMTD and use, it can be used for continuous vulcanization. Accelerator with thiazoles second time promoting agents, anti-old properties of vulcanized rubber declined to be accompanied by appropriate antioxidant. In chloroprene rubber, plasticizer and shrink solution agent. 2. using this compound has discoloration, therefore not suitable for white and light-colored rubber products, and rubber products in contact with food. 3. accelerator D is mainly used to produce rubber, shoe soles, industrial products, tires, hard plastic and thick-walled products. 4. The product as a secondary accelerator in an amount of 1-2 parts, when as thiazole accelerators secondary accelerator is generally used in an amount of 0.1 to 0.5 parts. Its chrome cheese diphenyl guanidine derivative is an effective rust inhibitor. Also used plastic crosslinking agents, showing temperature materials, ore floating selection of additives, paint additives, polishing materials, additives, metal analysis reagents and building material additives.
