Zusammenfassung:	The invention discloses a method for preparing environment-friendly high-strength tire reclaimed rubber through microwaves. The preparation method includes the following steps that rubber powder obtained after waste products are crushed, softener, compound regenerant and a coupling agent are mixed to prepare initially-modified rubber powder, wherein the tensile strength of the rubber powder is larger than or equal to 25 MPa, and the elongation at break is larger than or equal to 500%; microwave reclaimed rubber is prepared under the conditions that the radiation frequency is 2,450 MHz, the microwave radiation power ranges from 800 W to 1,200 W and the microwave radiation time is controlled to range from 1 min 40 s to 2 min 30 s, the microwave reclaimed rubber immediately enters a cooling device to be cooled and refined, and then the reclaimed rubber is obtained. Compared with a traditional waste rubber high-temperature regeneration method, by means of the method for preparing the environment-friendly high-strength tire reclaimed rubber, a molecular backbone is protected against damage, cross bonds can be broken, regeneration time is short, regeneration temperature is low, production efficiency is 5 times that of the traditional method, the performance of recycled rubber is reserved, and remarkable economic benefits and social benefits are achieved.
