Abstract

The invention belongs to the technical field of waste rubber reprocessing, and relates to a method for processing 400 mesh white rubber powder by using waste white rubber. According to the present invention, the normal temperature mechanical processing is used, and the waste white rubber scraps are subjected to washing, impurity removing, crushing, magnetic separation metal removal, multiple crushing, auxiliary agent adding, and grinding to prepare the 400 mesh white rubber powder; and the method has characteristics of rational process design and low energy consumption, the problem that the particle size of the rubber particles crushed by the common machine is large is solved, the performance of the obtained 400 mesh white rubber powder geometric material after the crushing is substantially superior to the performance of the rubber powder produced through the freezing method, the environmental pollution problem caused by direct discarding of the waste white rubber scraps is solved, and the waste white rubber scraps are turned into treasure.

Description

technical field [0001] The invention belongs to the technical field of waste rubber reprocessing, and relates to a method for processing 400-mesh white rubber powder by using waste white rubber. Background technique [0002] Thermoplastic elastomer modified plastic is a saturated polymer material, the appearance is white powder, non-toxic and tasteless, it has good weather resistance, ozone resistance, chemical resistance and aging resistance, and has good oil resistance, flame retardancy and coloring performance.
