Method for acquiring oder free butylbenzene reclaimed rubber with decomposition method

Abstract

The invention relates to a method for obtaining odorless regenerated styrene-butadiene rubber through treatment of waste vehicle tires by the decomposition method, which is characterized by comprising the following steps: firstly, the waste vehicle tires are crushed into 30 meshes by a crusher, and steel wires are peeled off; secondly, impurities are separated; thirdly, crushed rubber particles are placed into a cylinder; thirdly, a rubber fat splitting agent is poured into the cylinder and uniformly stirred; fifthly, the stirred rubber particles are poured into a rubber dynamic desulfurization tank for dynamic desulfurization, and the rubber dynamic desulfurization tank is pressurized to between 15 and 18 kilograms, heated to between 200 and 240 DEG C, and stands for 3 hours under the pressure and at the temperature; sixthly, rubber is subjected to mechanical desulfurization by a rubber mill; and seventhly, the rubber is subjected to mechanical pressing by a rubber refining mill. The method has the advantages that the regenerated styrene-butadiene rubber produced by the decompositions method is odorless, and the method does not pollute the environment in the production process, meets the requirements of physiochemical indexes, and can simultaneously meet the requirement of recycling of the rubber.

Description

technical field [0001] The invention relates to a method for treating waste car tires by a decomposition method, in particular to a method for treating waste car tires by a decomposition method to obtain odorless styrene-butadiene regenerated rubber. Background technique [0002] With the development of the current society, people pay more and more attention to the beauty of our living environment, and sustainable development is deeply rooted in the hearts of the people. Now, in order to make full use of recycled waste rubber, people have changed the previous treatment methods that pollute the living environment such as incineration and landfill. There are many ways to deal with the regeneration of waste rubber, such as using waste gas rubber particles as fillers for road construction, but since the effective use and recycling of resources is the basis for sustainable development of the country, the ones that are vigorously developed now will be waste The rubber can be reuse...
