Problems solved by technology

For the microwave rubber regeneration method, there are related equipment abroad, but the cost is very high
In addition, in the process of use, there are also problems such as the heat accumulated in the reclaimed rubber during the desulfurization period will be scorched and charred due to oxidation in the air, and the compounding ingredients in the rubber will also decompose, resulting in the deterioration of the performance of the regenerated rubber.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] The essence of microwave desulfurization is that the polar groups in the cross-linked network absorb the microwave energy and convert it into kinetic energy of molecular thermal motion, or due to the internal friction between the polar group and the surrounding network due to orientation polarization, enough heat is generated to promote chemical bonds. A break occurs. Through the processing of literature data, the fracture time of different cross-linking points is calculated, and it is believed that microwave desulfurization can achieve carbon black aggregates, carbon black-rubber, carbon-hydrogen bonds, polysulfur cross-links, low-sulfur cross-links, carbon-carbon The bonds are broken in sequence to control the best desulfurization effect. The desulfurization process may be accompanied by side reactions such as thermo-oxidative aging, cyclization and re-crossl...

Description

technical field [0001] The invention belongs to the field of rubber regeneration processing, and in particular relates to a rubber microwave regeneration linkage device. Background technique [0002] The development of the transportation industry has promoted the rapid development of the rubber industry. At the same time, the number of scrapped rubber products, mainly waste tires, is also increasing. The production of waste rubber products not only pollutes the environment, but also wastes resources. Therefore, the disposal of waste rubber products has become one of the effective ways to be solved urgently by the environmental protection industry and the rubber industry in various countries. [0003] The recycling of waste rubber has always been a research topic of widespread concern. The relative scarcity of various raw materials such as raw rubber and the continuous accumulation of a large amount of waste vulcanized rubber have prompted people to work hard to find out va...
