Problems solved by technology

[0003] However, peptizers are usually added to the plastic process in the form of powder in the current application. The powdery solid is more troublesome in the weighing process, and there will be powder in the weighing process, which will affect the safety and hygiene of the working environment. When the feed is added, it will also cause dust to fly, which will pollute the working environment in the workshop and damage the health of the staff

Abstract

The invention provides an environmentally friendly granular peptizer, characterized in that the peptizer comprises the following components according to weight fraction: 200-400 parts of a peptizer DBD powder (2,2 '-dibenzoylamino diphenyl disulfide); 300-600 parts of organic carrier; 150-200 parts of inorganic carrier; and 2.5-5 parts of colorant. The invention also provides a preparation methodof the environmentally-friendly granular peptizer. The environmentally-friendly peptizer DBD (2,2 '-dibenzoylamino diphenyl disulfide) is used as main raw material, and through adding different organic carriers and mixing the inorganic carrier, that environmentally-friendly granular peptizer is prepared, so that in the weighing and adding process of the product, the work environment is guaranteedto be clean, powder-free, and the health of the staff is protected.

Description

technical field [0001] The invention belongs to the technical field of rubber additives, in particular to an environment-friendly granular peptizer and a preparation method thereof. Background technique [0002] Mastication is a process of rubber processing, which uses mechanical or chemical methods to reduce the relative molecular weight and viscosity of raw rubber to improve its plasticity and obtain proper fluidity to meet the needs of further processing of raw rubber. Peptizer DBD is a new type of environmentally friendly, non-toxic, high-efficiency peptizer. The mechanism of its use in plasticizing raw rubber is that the peptizer DBD decomposes into sulfur-containing free radicals under the action of heat. On the one hand, it acts as a free radical On the other hand, it captures the hydrogen atoms in the macromolecular chain of raw rubber, promotes the breakage of the rubber molecular chain, achieves the purpose of reducing the molecular weight of raw rubber and improvi...
