preparation example Construction

[0027] The invention provides a preparation method of a nano-modified halogen-free wear-resistant cable material, which comprises the following steps:

[0028] 1. Weigh raw materials according to the formula;

[0029] 2. Mix the mixture prepared in 1 in the mixing tank for 5-20 minutes; the speed is 200-600 rpm;

[0030] 3. Put the mixed raw materials in a twin-screw extruder for plasticization and granulation. The processing temperature is 140-1250°C in the first zone, 150-160°C in the second zone, 150-170°C in the third zone, and 160-160℃ in the fourth zone. 185°C, 175-195°C in the fifth zone, 180-205°C in the sixth zone, and 170-190°C in the seventh zone.

[0031] 4. In the production process, the rubber is extruded from the extruder, drawn, water-cooled, dried, pelletized and packaged.

[0032] For the convenience of further understanding of the present invention, now in conjunction with specific embodiment the present invention is described in detail:

[0033] In an em...

Abstract

The invention discloses a nano modified halogen-free wear resistant cable material and its preparation method, an elastomer in the modified halogen-free wear resistant cable material is composed of hydrogenated styrene-butadiene-styrene, polyethylene, or hydrogenated styrene-isoprene-ethylene branched isoprene-styrene, and white oil, nano silicon nitride, fillers, a lubricant and an antioxidant are clathrated. The above components are mixed and granulated under a proper weight portion, the preparation technical flow comprises the following steps: the components are mixed for 5 to 20 minutes in a stirring machine and then are plasticized in a double-screw rod machine, pulled into strips, granulated, air-cooled and packaged. The cable material products prepared by the prescription and method have the advantages of convenient treatment, good hand feeling, strong wear resistance and cyclic utilization.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a nano-modified halogen-free wear-resistant cable material and a preparation method thereof. Background technique [0002] Nowadays, when many cable materials are used, their wear resistance often does not meet the requirements of the use environment, which limits the service life of the cable itself under certain circumstances, and also brings potential harm to environmental safety. For those with wear resistance requirements For wire and cable, a specially developed nano-modified halogen-free wear-resistant cable material is used for locomotive cables, mining cables, earphone cables, etc. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a nano-modified halogen-free wear-resistant cable material and a preparation method thereof. [0004] In order to solve the above technical problems, the object of the pres...
