Embodiment 1

[0024] Example 1 According to the following parts by mass: NBR: 70 parts, PVC: 30 parts, carbon black (N330): 50 parts, LNBR: 30 parts, RD: 1.5 parts, 4010NA: 1.5 parts, sulfur: 1.2 parts, DCP: 0.5 parts, CZ: 1.2 parts, TMTD: 0.3 parts, stabilizer: 1.8 parts, ZnO: 5.0 parts, stearic acid: 1.5 parts.

[0025] A kind of NBR / PVC elastomer with LNBR described in the present embodiment as plasticizer, the preparation steps of its compounded rubber and its vulcanized rubber:

[0026] (1) NBR mastication: masticate NBR on an open rubber mixer, and add anti-aging agent to mix evenly;

[0027] (2) NBR / PVC blending: Heat the plastic mixer to 150~160°C, put the PVC / stabilizer evenly mixed with a high-mix mixer on the roller of the plastic mixer for plasticization, and when it reaches the plasticized state Add NBR for blending, mix evenly and then slice, cool for later use;

[0028] (3) Preparation of mixed rubber: put the NBR / PVC blended rubber obtained in step (2) on the roller of the...

Embodiment 2

[0031] Example 2 According to the following parts by mass: NBR: 70 parts, PVC: 30 parts, carbon black (N330): 30 parts, LNBR: 30 parts, RD: 1.5 parts, 4010NA: 1.5 parts, sulfur: 1.2 parts, DCP: 0.5 parts, CZ: 1.2 parts, TMTD: 0.3 parts, stabilizer: 1.8 parts, ZnO: 5.0 parts, stearic acid: 1.5 parts. The difference between the ratio of this example and Example 1 is that 30 parts of carbon black (N330) are used.

[0032] The preparation method and performance testing standard of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention discloses an NBR / PVC elastomer by taking LNBR as a plasticizer and a preparation method of the elastomer and relates to a rubber blended elastic material and a preparation method thereof. The elastomer consists of the following components in parts by mass: 70 parts of butadiene-acrylonitrile rubber, 30 parts of polyvinyl chloride (PVC), 10-50 parts of reinforcing agent, 10-30 parts of plasticizer, 2.5-3.5 parts of anti-aging agent, 1.0-2.0 parts of vulcanizing agent, 5.0-7.0 parts of vulcanizing activator, 1.0-2.0 parts of vulcanization accelerator and 1.5-2.0 parts of stabilizer. According to the preparation method of the elastomer, the used vulcanizing temperature is 165 DEG C, so that the elastomer has excellent performances such as hot air aging resistance, wear resistance, fatigue resistance and solvent extraction resistance. The elastomer can be widely applied to the industries such as printing rubber rolls, fuel oil rubber tubes and accumulator capsules.

Description

technical field [0001] The invention relates to a rubber blended elastic material and a preparation method thereof, in particular to an NBR / PVC elastomer with LNBR as a plasticizer and a preparation method thereof. Background technique [0002] Nitrile rubber (NBR) has excellent oil resistance, heat resistance and physical and mechanical properties, but its ozone aging resistance is poor; while general-purpose synthetic resin polyvinyl chloride (PVC) has excellent flame retardancy and self-extinguishing properties As well as ozone aging resistance, chemical corrosion resistance, electrical insulation, chemical stability and thermoplasticity, but its toughness is low, it is not impact resistant, and its heat resistance is poor. [0003] Both NBR and PVC are polar polymers, the solubility parameters of the two are similar (9.64, 9.6 respectively), the compatibility is very good, and they can be blended in any proportion. The composite material made of the two blends is not...
