Embodiment 1

[0008] Embodiment 1. Under the existing processing technology conditions, including batching-mixing-discharging-sheet-vulcanization-test. The ingredients include the following raw materials: 100 grams of nitrile rubber, 5 grams of zinc oxide, 3 grams of stearic acid, 1 gram of DM accelerator, 2 grams of sulfur, 2 grams of IPPD anti-aging agent, 5 grams of DBP softener and 60 grams of natural gas channel carbon black gram.

Embodiment 2

[0009] Embodiment 2. Under existing processing technology condition, batching comprises following raw material: nitrile rubber 100 grams, zinc oxide 5 grams, stearic acid 3 grams, DM accelerator 2 grams, sulfur 2 grams, IPPD antioxidant 2.0 grams, 8 grams of soft DBP agent and 100 grams of natural gas channel black.

Embodiment 3

[0010] Embodiment 3. Under existing processing technology condition, batching comprises following raw material: nitrile rubber 100 grams, zinc oxide 5 grams, stearic acid 3 grams, DM accelerator 2 grams, sulfur 2 grams, IPPD antioxidant 2 grams, 10 grams of softening DBP agent and 120 grams of natural gas channel black.

[0011] Test results: After several tests, with the help of existing equipment and process conditions, the tear strength of the piston cup rubber material can reach more than 80KN / m, thereby improving the service life of the product, from the original use of one month to the present more than three months.

Abstract

The invention relates to a preparation method of a high-strength piston leather cup material and belongs to the field of industrial rubber materials. The technical proposal is as follows: the high-strength piston leather cup material is prepared by the following procedures of batching materials, mixing, calendaring, sulfuration and inspection, wherein, the batched materials comprise nitrile rubber, an accelerating agent, zinc oxide, stearic acid, an aging inhibitor, a softener and carbon black as a reinforcing agent; the materials in batching also comprise sulfur; and the carbon black as the reinforcing agent is carbon black which is prepared by a natural air tank method. The parts by weight of the materials are as follows: 100 parts of nitrile rubber, 5 parts of zinc oxide, 3 parts of stearic acid, 1 to 2 parts of DM accelerating agent, 1 to 3 parts of sulfur, 2 to 3 parts of IPPD aging agent, 5 to 10 parts of DBP softener and 60 to 120 parts of carbon black prepared by the natural air tank method. The material processed by using the method has tear strength of 80.28KN / m by sulfuration and inspection, thus improving the service life of the product.

Description

technical field [0001] The invention relates to a preparation method of a high-strength piston cup material in the field of industrial rubber materials. Background technique [0002] At present, the preparation method of piston rubber cup material is with 100 parts of nitrile rubber, accelerator DM1.5, zinc oxide 4.0 stearic acid 2.0, antioxidant 2.0, softening agent 10 parts, N660 carbon black 100 parts (all are parts by weight) ). After batching-mixing-sheet-out-vulcanization-inspection-packaging. The piston cup material prepared by the method is punched with a 90-degree cutting knife, tested on an electronic tensile machine, and the tear strength is 35KN / m, and the service life of the product is short, usually about 30 days. Contents of the invention [0003] The purpose of the present invention is to aim at the above-mentioned defects of the leather cup material prepared by the existing preparation method, and on the basis of repeated research and experiments, propos...
