Application of waste rubber powder after modification

Waterproof coil is an important material needed by the construction industry and other related industries. As most of the raw materials such as EPDM and butyl rubber need to be imported, the price of polymer waterproof coil is relatively high, which has become a big problem that has troubled China's polymer waterproof coil for a long time. Therefore, some enterprises are using waste rubber powder to modify asphalt waterproof roll, and occupy a certain market for a long time. However, due to different use conditions and different performance requirements, the production process and product development of reclaimed rubber waterproof roll are also different (including high strength PP reclaimed rubber waterproof roll, enhanced composite radiation resistant waterproof roll, nano composite flexible waterproof roll, etc.).

Preparation of waste rubber powder from asphalt

Waste rubber powder modified asphalt is waste tire as raw material, adding modifiers, softening agents, auxiliary materials, after screw plasticizing and regeneration of modified rubber powder, the product used in waterproof roll material and highway asphalt can effectively improve product performance, reduce the cost of modified asphalt.
