Problems solved by technology

[0004] However, when the US ASTM D471 standard is used for testing, the various test standard oils IRM901, IRM902, IRM903, and IRM905 that need to be used have no corresponding products and formulas in China, and they all need to be imported from the United States, which is expensive and increases the cost.

Embodiment 1

[0017] The rubber liquid of the present invention affects the experiment with the component weight ratio of standard oil as follows:

[0018] Diisoamylnaphthalene 11.7kg, KN4010 naphthenic rubber oil 24kg, KN4006 naphthenic rubber oil 44kg, KG-12 rubber oil 8kg, KG-06 rubber oil 12kg, antioxidant T501 0.3kg.

[0019] Mix the above diisoamylnaphthalene, KN4010 naphthenic rubber oil, KN4006 naphthenic rubber oil, KG-12 rubber oil, KG-06 rubber oil, and antioxidant T501 evenly.

Embodiment 2

[0021] The rubber liquid of the present invention affects the experiment with the component weight ratio of standard oil as follows:

[0022] Diisoamyl naphthalene 12kg, KN4010 naphthenic rubber oil 26.2kg, KN4006 naphthenic rubber oil 43kg, KG-12 rubber oil 6.6kg, KG-06 rubber oil 11.3kg, antioxidant T501 0.3kg, polyisobutylene 0.6 kg.

[0023] Mix the above diisoamylnaphthalene, KN4010 naphthenic rubber oil, KN4006 naphthenic rubber oil, KG-12 rubber oil, KG-06 rubber oil, antioxidant T501, and polyisobutylene evenly.

Embodiment 3

[0025] Rubber liquid of the present invention influences experiment to use standard oil configuration process as follows:

[0026] Get 12.2kg of diisoamylnaphthalene, 27.5kg of KN4010 naphthenic rubber oil, 41.4kg of KN4006 naphthenic rubber oil, 7kg of KG-12 rubber oil, 11kg of KG-06 rubber oil, and 0.3kg of antioxidant T501 and mix evenly. After testing its viscosity is 19.63, add 0.6kg of polyisobutylene, and mix evenly.

Abstract

The invention discloses standard oil replacing IRM902# standard oil and used for rubber oil-resistant detection and a preparation method of the standard oil. The standard oil comprises the following components, by weight ratio, 11.5-12.5% of diisoamyl naphthalene, 20-40% of KN4010 cycloalkyl rubber oil, 30-60% of KN4006 cycloalkyl rubber oil, 5-15% of KG-12 rubber oil, 10-20% of KG-06 rubber oil, and 0.1-0.5% of an anti-oxidant T501. The formula is independently researched and developed, and the standard oil is used for replacing IRM902# standard oil imported from the America. The adopted raw materials can be bought at home, so that import is avoided and the cost is effectively reduced.

Description

technical field [0001] The invention belongs to the field of rubber detection, and in particular relates to a standard working fluid for rubber oil resistance detection. Background technique [0002] Rubber oil resistance is an important performance index of oil-resistant rubber. Kebiao Testing Center provides rubber oil resistance test in accordance with GB, HB, ISO, ASTM, EN and other standards, and issues a report. In the existing tests, the American ASTM standard is mostly used to test the oil resistance of rubber. [0003] Due to the current American ASTM new standard has adjusted the quality of its oil products, and in the new standard, the original No. 1, 2, 3, and 5 test standard oils have been upgraded to IRM 901, IRM902, IRM903, and IRM905. They are mainly used for oil resistance tests of rubber sealing products, such as oil seals (NBR nitrile rubber oil seals, ACM acrylate oil seals, etc.), O-rings and hose products. Different rubber materials can be tested acc...
