Examples
Embodiment 1
[0032] Example 1: A processing method for 95-degree grade PVC cable materials, including batching, kneading, mixing and compression molding, etc. In these steps, except that the batching has been improved, the remaining steps and corresponding process conditions are the same current technology.
[0033] The batching is: the raw material is composed of the following ingredients in parts by weight:
[0034]
[0035]After testing, in the above waste carbon mud containing plasticizer, the weight content of TOTM is about 40%, the weight content of activated carbon is about 58%, and the weight content of refined additive is about 2%. Refined additives mainly refer to diatomaceous earth, aluminum oxide, kaolin, magnesium oxide, white clay, etc.
[0036] TOTM, ie, tris(2-ethyl)hexyl trimellitate.
[0037] The organotin heat stabilizer, for example, can be selected from the HTM-2010 methyl tin heat stabilizer in the HTM series of Zhejiang Hepton New Materials Co., Ltd.

Embodiment 2
[0042] Example 2: A processing method for 105-degree PVC ordinary sheathed cable materials, including batching, kneading, mixing and compression molding, etc., in these steps, except that the batching has been improved, the remaining steps and corresponding processes Conditions are all the same as the prior art.
[0043] The batching is: the raw material is composed of the following ingredients in parts by weight:
[0044]
[0045] The calcium-zinc composite heat stabilizer can be selected from the HCZ-1086 calcium-zinc composite heat stabilizer in the HCZ series of Zhejiang Hypton New Materials Co., Ltd.
[0046] The waste carbon mud that contains plasticizer TOTM is the same as embodiment 1.
[0047] Its main performance parameters are described in Table 2 below:

[0049] project name
Embodiment 3
[0050] Embodiment 3: A kind of processing method of dark PVC sole material, comprises batching, kneading, kneading and pressing molding etc., in these steps, except that batching has been improved, all the other steps and corresponding technological conditions are all the same as prior art .
[0051] The batching is: the raw material is composed of the following ingredients in parts by weight:
[0052]
[0053] In the above-mentioned waste carbon mud containing DOP, the weight content of DOP is about 45%, the weight content of activated carbon is 52%, and the weight content of refined adhering agent is about 3%.
[0054] Its performance parameters are shown in Table 3 below:
