Embodiment Construction

[0006] One-step vulcanization and rubber mixing method, using EPDM rubber as raw material, using a rubber cutter to cut the rubber into required sizes, adding sulfur and its additives (according to the mass fraction ratio): EPDM G-6470 100 parts, zinc oxide 5-8 parts, 1-2 parts of stearic acid, 110-120 parts of carbon black, 55-60 parts of paraffin oil, 1.5 parts of sulfur, 1.5 parts of ZDBC, 1.2 parts of MBT, 0.8 parts of TMTD, put the above materials together Put it into the internal mixer and knead at a temperature of 90-115°C and a pressure of about 100MPa. After kneading for 350 seconds, the rubber and sulfur are fully blended. After the kneading is completed, put the kneaded rubber on the rubber rack .

[0007] On the premise of ensuring the performance of the compounded rubber, the present invention only adopts one-time vulcanization and compounding, the procedure is simple, and at the same time, it saves 72 hours of material preparation time and reduces the compounding...

Abstract

The invention provides a one-step sulphurating rubber-refining method comprising the following steps of: with ethylene propylene diene rubber as a raw material, slicing the rubber into needed dimensions by using a rubber cutting machine; adding sulphur and additives thereof (by mass fraction ratio): 100 parts of EPDMG-6470, 5-8 parts of zinc oxide, 1-2 parts of stearic acids, 110-120 parts of carbon black, 55-60 parts of paraffin oil, 1.5 parts of the sulphur, 1.5 parts of ZDBC, 1.2 parts of MBT and 0.8 part of TMTD (Tetramethylthiuram Disulfide); adding the materials to an internal mixer together; mixing at the temperature of 90-115 DEG C and the pressure of about 100 MPa for 350 seconds, and then sufficiently mixing the rubber and the sulphur; and after the mixing is completed, placing the mixed rubber to a rubber rack. The invention only adopts one-time sulphurating mixing under the precondition of ensuring the property of the mixed rubber and has simple process.

Description

technical field [0001] The invention relates to a rubber mixing method, in particular to a one-step vulcanization rubber mixing method. Background technique [0002] At present, in the field of rubber vulcanization processing, the usual processing method is: mix the original rubber with sulfur and other additives for about 150 seconds, and then park the mixed rubber for 24-72 hours, then add the additives, and carry out The second mixing is about 70 seconds, and it can be used in various production and processing after the second mixing is completed. This segmented rubber mixing method needs to be mixed first, then parked, and finally mixed. This process is cumbersome, takes a long time to process and consumes a lot of human resources. Contents of the invention [0003] The object of the present invention is to provide a rubber processing technology with reasonable production, simple process, short processing cycle and energy saving. [0004] The technical scheme of the ...
