Abstract

The invention relates to the technical field of diphenylguanidine production, and in particular discloses a method for improving the quality of a diphenylguanidine product. The method for improving the quality of the diphenylguanidine product takes diphenylthiourea as a raw material and is characterized by grinding the diphenylthiourea, throwing ammonium hydroxide and the diphenylthiourea into an oxidation pot according to the weight ratio being (7 to 10):1 for pulping, then pumping oxygen into the oxidation pot at the temperature of 55 to 85 DEG C, stopping oxygen pumping when a reaction reaches an end point, and then obtaining the diphenylguanidine product through washing and drying. The method provided by the invention is simple in step, convenient to operate, and easy to industrialize, the obtained product is white in appearance, and high in purity, the improvement of product quality is facilitated and the method is suitable for wide popularization and application.

Description

(1) Technical field

[0001] The invention relates to the technical field of diphenylguanidine production, in particular to a method for improving the quality of diphenylguanidine products. (2) Background technology

[0002] With the development of society and the continuous advancement of technology, green tires are constantly connected with green manufacturing. The green tires in people's eyes are not only the concept of "silicon tires", but the greening of the whole production process of tires is a strategic goal. Green tires are inseparable from the use of white carbon black (SiO2). As a non-fossil reinforcing material, white carbon black also has a very important contribution to environmental protection. The accelerator diphenylguanidine can significantly accelerate the silanization reaction between silica and Si69, reduce the Payne effect of the system, and improve the physical and mechanical properties of the rubber compound.
