Abstract
The invention relates to a method for degrading polypropylene plastic, and belongs to the field of polymer materials. The method is characterized by including the following steps: heating the polypropylene plastic to a molten state; adding a Z-N catalyst and ferric chloride; carrying out ultraviolet irradiation to achieve degradation of polypropylene plastic into propylene monomer, wherein the ultraviolet irradiation intensity is 100-200 muW/cm<2>. The method has the benefits that iron trichloride is added to the catalyst, and continuous intense ultraviolet radiation is adopted, so as to increase the degradation speed and reduce the recycling cost.
Description
Technical field
The present invention relates to a kind of degradation method of acrylic plastering, belong to polymeric material field.
Background technology
After acrylic plastering uses for some time, progressively degrade, when needs carry out recycling to it, traditional degradation speed is slow, improves degraded cost recovery.
