The used rubber powder made from the waste tire rubber by crushing and mechanical shearing is a kind of thermosetting polymer

which is difficult to degrade and has high recycling cost. And the mechanical properties are poor due to structure damage in the process of processing rubber powder

limiting its application. However

it still has a certain degree of elasticity

wear resistance and skid resistance

and some excellent properties of rubber. It can also be used after proper modification

and it is expected to replace the rubber in short supply

as well as the prepared sheet and pavement materials. In this paper

the application fields and research status of used rubber powder at home and abroad were reviewed

especially the application and research status of corn straw modified used rubber powder composites were reviewed and analyzed

and on this basis

the application prospect of corn straw modified used rubber powder composites was prospected.
