Embodiment 1
[0037] Each raw material and its mass parts are:
[0038] Waste rubber powder 100.00
[0039] Softener naphthenic oil 10.00
[0040] Composite activating regeneration agent 420 / M0.70
[0041] Coupling agent KH5702.00
[0042] The composite activated regenerant 420 / M is composed of activated regenerated agent 420 and activated regenerated agent M, and is formulated according to the mass ratio of regenerated agent 420:regenerated agent M=1:1.
[0043] Its preparation method, carry out as follows:
[0044] Step 1) Screening: use waste truck tires and / or engineering tires with tensile strength ≥ 25MPa and elongation at break ≥ 500%, and prepare waste rubber powder of about 20 meshes by crushing;
[0045] Step 2) Put the waste rubber powder on the open mill, add softener naphthenic oil, compound regeneration agent 420 / M, coupling agent KH570 in turn, carry out thin pass mixing for 10 minutes, and control the temperature of the open mill at 40±5 ℃, the roller distance is contro...
