Waste rubber dissolving and regenerating device and regenerating method

Abstract

The invention discloses a waste rubber dissolving and regenerating method which comprises the following steps: putting waste rubber into a dissolving agent, and vibrating the dissolving agent under the action of ultrasonic waves. The dissolving agent has swelling and dissolving effects on waste rubber, the cavitation effect of ultrasonic waves has a selective bond breaking effect on a rubber cross-linked network structure, the ultrasonic cavitation effect can be achieved through a liquid medium, the dissolving agent is used as the liquid medium of the ultrasonic cavitation effect, and the swelling and dissolving effects and the ultrasonic bond breaking effect of the dissolving agent are combined, thus the effect of the dissolving agent is promoted, dissolving of the waste rubber is accelerated and the waste rubber regeneration efficiency is improved. Moreover, no depolymerization harmful gas and no waste liquid are generated in the regeneration process, and green and environment-friendly dissolution and regeneration of the waste rubber can be realized. The invention further provides a waste rubber dissolving and regenerating device which comprises a reactor and an ultrasonic generator, the reactor can contain the waste rubber material and the dissolving agent, the ultrasonic transducer is arranged in the reactor, and the ultrasonic generator is connected with the ultrasonic transducer.

Description

technical field [0001] The invention relates to the technical field of waste rubber regeneration, in particular to a waste rubber dissolving and regeneration device and regeneration method. Background technique [0002] For rubber products that have been chemically cross-linked, they have a stable three-dimensional network structure inside, cannot decompose by themselves, and can still maintain their original shape after long-term sun and rain. Its regeneration requires long-term high-temperature desulfurization, resulting in secondary energy consumption, and Performance drops significantly after regeneration. As a major producer of reclaimed rubber, high-temperature dynamic desulfurization technology has been used in the production of reclaimed rubber in my country. This traditional high-pollution, high-energy-consuming regeneration method is facing being eliminated. [0003] In order to realize the green and high-efficiency regeneration of waste rubber, people have develo...

[0004] The Chinese patent with publication number CN207451993U discloses an improved structure for rubber ultrasonic sulfur breaking and regeneration, which belongs to the technical field of rubber sulfur breaking and regeneration, and provides a Rubber ultrasonic regeneration equipment adopts ultrasonic blades. Ultrasonic not only grinds waste rubber, but also breaks the vulcanization bonds of rubber powder in large quantities at the same time, so that the rubber powder has higher activity and has better performance than rubber powder produced by conventional methods. Applied performance, but its regeneration efficiency is low
