| 橡膠促進(jìn)劑ZBEC Rubber Accelerator ZBEC 000化學(xué)名稱(chēng)Chemical Name 二芐基二硫代氨基甲酸鋅（zinc dibenzyl dithiocarbamate） 結構式Molecular Structure
C30H28S4ZnN2 分子量 Molecular Weight 610CAS# 14726-36-4 技術(shù)指標 Specifications
性質(zhì) 相對密度1.14。熔點(diǎn)不小于178℃。溶于乙醇、苯和氯仿，不溶于水。貯存穩定。
用途 天然膠，合成膠及膠乳用超速促進(jìn)劑。其硫化活性溫度較低， 可替代ZDBC、ZDEC、PZ等使用，且操作安全性更佳。尤其突出的是，本品在橡膠加工過(guò)程中不會(huì )產(chǎn)生致癌性的亞硝胺。本品還可作為噻唑類(lèi)促進(jìn)劑的優(yōu)良的活性劑。使用本品時(shí)，氧化鋅和硫黃的配合量一般，脂肪酸可用可不用。它可以直接加入膠料，也可以做成分散體加入膠乳。在與食品接觸的橡膠制品中的應用，請參照FDA、BgVV有關(guān)章節中的規定。
貯存 密封儲存在陰涼、干燥、通風(fēng)良好的地方。避免陽(yáng)光直射。
包裝 復合紙袋，內襯塑料薄膜袋，凈重25公斤。
Properties Relative density is 1.14. melting point is above 178℃. Soluble in alchohol, benzene, chloromethane, insoluble in water. Storage is stable.
Applications A overspead accelerator for natural and synthetic rubber and latex. Curing active temperature is low. It can substitute for ZDBC、ZDEC、PZ, ect.. Operating safety is much better. Specially , it will not produce cancer-causing nitrosamize during the rubber manufacturing process , and it can be used as excellent activator to kinds of thiazole. Appropriate matching quantity of Zine oxide and sulfur when using , and aliphatic acid is not necessary .it can be added directly into rubber mass and also can be added into latex as component part. ZBEC is regulated for use in articles in contact with food as specified under FDA 21 CFR 175.105,177.2600 and under BgVV XXI, Categories 1-4 and"Sonderkategorie".
Storage Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight. Packing 25kg net paper bags lined with polyethylene film bags. |
