Embodiment 1

[0029] A preparation process of high-performance rubber for generator shock pads, comprising the steps of:

[0030] ①Premixing: Use an appropriate amount of xylene solution as a solvent, heat it to 80°C, add 0.5 parts of m-phenylenediamine, and after it is completely dissolved, add 0.5 parts of accelerator BMI, stir at 90°C for 5 minutes, and mix xylene Evaporate it, then dry it in an oven at 60°C for 5 minutes, grind it into powder with a pulverizer, and set aside;

[0031] ②Mixing: Add 0.1 part of peptizer DBD to 100 parts of natural rubber, plasticize 5 times on the double-roller open mill, and after wrapping evenly, add 4 parts of 100 mesh zinc oxide and 0.9 parts of Fatty acid, 0.2 parts of anti-scorch agent CTP, and then add 28 parts of spray carbon black for mixing. The mixing temperature of the front roll is 55 ° C, and the mixing temperature of the rear roll is 50 ° C. After the mixing is uniform, the material is discharged;

[0032] ③Vulcanization: Put the film made...

Embodiment 2

[0034] On the basis of the process in Example 1, the following formula and process parameters were changed: in the premixing step, 0.55 parts of m-phenylenediamine and 0.55 parts of accelerator BMI were used, and stirred at 90°C for 6 minutes; in the mixing step, 0.15 parts of Peptizer DBD, 4.5 parts of 100-mesh zinc oxide, 1 part of stearic acid, 0.25 parts of anti-scorch agent CTP, and then add 30 parts of spray carbon black for mixing. The mixing temperature of the front roller is 57 ° C, and the mixing temperature of the rear roller The temperature is 52°C; in the vulcanization step, add 3 parts of vulcanizing agent DCP, and vulcanize under normal pressure at 170°C for 27 minutes to obtain the desired product.

Embodiment 3

[0036] On the basis of the process in Example 1, the following formula and process parameters were changed: in the premixing step, 0.6 parts of m-phenylenediamine and 0.6 parts of accelerator BMI were used, and stirred at 90°C for 7 minutes; in the mixing step, 0.2 parts of Peptizer DBD, 5 parts of 100-mesh zinc oxide, 1.1 parts of stearic acid, 0.3 parts of anti-scorch agent CTP, and then add 32 parts of spray carbon black for mixing. The mixing temperature of the front roller is 60 ° C, and the mixing temperature of the rear roller The temperature is 55°C; in the vulcanization step, add 3.5 parts of vulcanizing agent DCP, and vulcanize under normal pressure at 175°C for 30 minutes to obtain the desired product.

Abstract

The invention discloses high-performance rubber for a generator shock pad and a preparation process thereof. Raw materials of the rubber comprise: natural rubber, DBD (Dibromodulcitol), 100-mesh zinc oxide, stearic acid, CTP (Cytidine Triphosphate), spraying carbon black, DCP (Dicalcium Phosphate), BMI (Bismaleimide Resin), TMTD (Thiram), CZ (Citrazinic Acid), m-phenylenediamine and bisphenol A type epoxy resin; and the preparation process comprises: premixing, mixing and vulcanizing. A rubber material is fully activated by mixing to improve the heat resistance, aging resistance and deformation resistance of the rubber material, the m-phenylenediamine and the BMI are pre-mixed before the vulcanizing procedure to improve the toughness of the BMI, the bisphenol A type epoxy resin is added with the m-phenylenediamine, the three components are compatible and perforative to improve the shearing strength and the aging resistance of the rubber, the CZ and the TMTD are added to further improve the curing speed and the scorch resistance, and the finally obtained rubber has good breaking strength and breaking elongation, proper hardness, excellent high temperature resistance and good damping effect.

Description

technical field [0001] The invention belongs to the technical field of rubber production for generator shock absorbing pads, and in particular relates to a high-performance rubber for generator shock absorbing pads and a preparation process thereof. Background technique [0002] With the rapid development of modern industry, the power of generators is increasing, and the hazards of vibration and noise are becoming more and more prominent. At present, the widely used method is to use rubber materials and skeleton materials (such as metal, fiber, engineering plastics, etc.) Composite shock absorbers or special rubber viscoelastic high damping materials are used to eliminate the vibration impact of the vibration source and absorb noise. The generator generates a lot of heat due to long-term work, and the rubber used for the shock pad of the generator is required to have high strength, High elongation, high wear resistance, high temperature resistance, and avoid thermal agin...
