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:

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:

Abstract

The invention discloses a method for preparing a polyvinyl chloride product from waste carbon paste produced by plasticizer production. The method comprises the following steps of material blending, kneading, mixing, and pressing molding. In the material blending, raw materials comprise 100 parts by weight of polyvinyl chloride, 3 to 35 parts by weight of at least one plasticizer, 20 to 60 parts by weight of plasticizer-containing waste carbon paste, 0 to 3 parts by weight of at least one heat stabilizer, 2 to 6 parts by weight of stearic acid or a stearate, and 2 to 10 parts by weight of an assistant. The method for preparing a polyvinyl chloride product solves environmental pollution problems and realizes secondary reasonable utilization of waste carbon paste. All performances of a polyvinyl chloride product prepared by the method satisfy requirements.

Description

technical field [0001] The invention belongs to the technical field of clean production of fine chemical production and application of polymer materials, and relates to a method for polyvinyl chloride (PVC) products, in particular to a method for preparing polyvinyl chloride from waste carbon mud produced in the production process of plasticizers (PVC) products. Background technique [0002] The production process of industrial plasticizers requires decolorization, refining and adsorption operations [1]. The decolorizing agent is activated carbon, and the refining agent is diatomite, aluminum oxide, kaolin, magnesium oxide, white clay, etc. The output of plasticizers in China has exceeded 2 million tons per year, and a large amount of waste solids (that is, waste carbon mud) are inevitably produced during the production process. The main components of this waste solids (that is, waste carbon mud) are Solid adsorbents with a certain specific surface and porous structure, suc...
