Problems solved by technology

[0002] The buffer rubber rope causes heat accumulation during the repeated stretching process. At the same time, due to the relatively large temperature difference between day and night in the north throughout the year, the buffer rubber rope produced with high-elastic rubber smoked natural rubber is very easy to age and crack, and cracks occur during the tensile stress. Under the action of rapid expansion and extension, it causes hidden dangers in equipment and some buffer equipment. Therefore, users must replace it early in the morning after obvious cracks occur.

Embodiment 1

[0023] Embodiment 1 Its raw material ratio is: 100 parts of 1# natural rubber, 1 part of sulfur, TT accelerator (Chinese name: tetramethylthiuram disulfide, molecular formula: C6H12N2S4) 0.2 part, CZ accelerator (Chinese name : N-cyclohexyl-2-benzothiazole sulfenamide, molecular formula: C13H16N2S2) 0.5 parts, zinc oxide 4 parts, stearic acid 0.9 parts, paraffin wax 0.9 parts, D antioxidant (Chinese name: N-phenyl- 2-naphthylamine, molecular formula: C16H13N) 1 part, anti-aging agent 4010NA (Chinese name: N-isopropyl-N'-phenyl-p-phenylenediamine, molecular formula: C15H18N2) 0.4 part.

[0024] The specific production steps are as follows:

[0025] Compound production

[0026] ⑴ Weigh various ingredients according to the specific formula ratio;

[0027] (2) Take 100 parts of 1# natural rubber and add it to the rubber mixing machine. After mixing for 2 minutes, add 1 part of sulfur, 4 parts of zinc oxide, 1 part of D antioxidant, and 0.4 part of 4010NA antioxidant and mix well...

Embodiment 2

[0036] The production process of embodiment 2 is identical with embodiment 1, and difference is that the rubber material component ratio is different, and the rubber material composition of embodiment 2 is calculated as follows by component: 1# natural rubber 110 parts, sulfur 2 parts, accelerator TT (Chinese name: tetramethylthiuram disulfide, molecular formula: C6H12N2S4) 0.25 parts, accelerator CZ (Chinese name: N-cyclohexyl-2-benzothiazole sulfenamide, molecular formula: C13H16N2S2) 0.55 parts, oxidation 5 parts of zinc, 1 part of stearic acid, 1 part of paraffin, anti-aging agent D (Chinese name: N-phenyl-2-naphthylamine, molecular formula: C16H13N) 1.5 parts, anti-aging agent 4010NA (Chinese name: N-isopropyl -N'-phenyl-p-phenylenediamine, molecular formula: C15H18N2) 0.5 parts.

Embodiment 3

[0037] The production process of embodiment 3 is identical with embodiment 1, and difference is that the ratio of rubber material components is different, and the rubber material composition of embodiment 3 is counted as follows by component: 120 parts of 1# natural rubber, 3 parts of sulfur, accelerator TT (Chinese name: tetramethylthiuram disulfide, molecular formula: C6H12N2S4) 0.3 parts, accelerator CZ (Chinese name: N-cyclohexyl-2-benzothiazole sulfenamide, molecular formula: C13H16N2S2) 0.6 parts, oxidation 6 parts of zinc, 1.1 parts of stearic acid, 1.1 parts of paraffin, 2 parts of anti-aging agent D (Chinese name: N-phenyl-2-naphthylamine, molecular formula: C16H13N), 2 parts of anti-aging agent 4010NA (Chinese name: N-isopropyl -N'-phenyl-p-phenylenediamine, molecular formula: C15H18N2) 0.6 parts.

Abstract

The invention relates to an anti-aging cushion rubber rope which is characterized by comprising the following raw materials: 100-120 parts of 1# natural rubber, 1-3 parts of sulfur, 0.2-0.3 part of TT accelerator tetramethyl-thiuram disulfide, 0.5-0.6 part of CZ accelerator N-cyclohexyl-2-benzothiazole sulphenamide, 4-6 parts of zinc oxide, 0.9-1.1 parts of stearic acid, 0.9-1.1 parts of paraffin, 1-2 parts of D anti-aging agent N-phenyl-2-naphthylamine and 0.4-0.6 part of 4010NA anti-aging agent N-isopropyl-N'-phenyl-p-phenylene diamine. The anti-aging cushion rubber rope has the advantages of favorable aging resistance and longer service life.

Description

technical field [0001] The invention relates to the field of rubber, in particular to an anti-aging buffer rubber rope. Background technique [0002] The buffer rubber rope causes heat accumulation during the repeated stretching process. At the same time, due to the relatively large temperature difference between day and night in the north throughout the year, the buffer rubber rope produced with high-elastic rubber smoked natural rubber is very easy to age and crack, and cracks occur during the tensile stress. Under the action, it rapidly expands and extends, causing hidden dangers in equipment and some cushioning equipment. Therefore, users must replace it early in the morning after obvious cracks occur. Contents of the invention [0003] The purpose of the present invention is to provide an anti-aging buffer rubber rope, which has good anti-aging performance and increases the life of the buffer rubber rope. [0004] The technical solution of the present invention is to...
