Tetrabutyl thiuram disulfide and preparation method thereof, and application of tetrabutyl thiuram disulfide

The invention provides tetrabutyl thiuram disulfide and a preparation method thereof and application of tetrabutyl thiuram disulfide, and relates to the technical field of synthetic rubber chemical additives. The preparation method comprises the following steps of: firstly, dropwise adding carbon disulfide into a di-n-butylamine aqueous solution to obtain a solution containing dibutlydithiocarbamate; and dropwise adding hydrogen peroxide into the obtained solution containing dibutlydithiocarbamate for reaction, and standing the solution to separate an oil phase, so as to obtain tetrabutyl thiuram disulfide. The preparation method has the advantages of the simple technological process, the high product yield, the high purity, the short production period, the energy conservation and consumption reduction, the appearance color of the product is consistent and amber, the product can be used for subsequent manufacturing of white or light-color rubber products, and the quality and yield of tetrabutyl thiuram disulf
