Problems solved by technology

However, the biggest disadvantage of polynorbornene rubber is that, like natural rubber, it does not have sufficient oil resistance (see Dr.-lng.W.Goht, "Elastomere Dicht-und Konstruktionswerkstoffe", P38), when it is used for reducing In the application of shock damping, especially for some mechanical equipment, it is often required to have a certain oil resistance. Therefore, it is of considerable practical significance to improve the oil resistance of polynorbornene rubber.

[0013] Preparation of masterbatch for blending and blending

[0014] For the convenience of showing the effect of the present invention, at first prepare polynorbornene rubber and nitrile rubber masterbatch respectively according to the formula shown in table 1, the polynorbornene rubber used is NS × 15AB produced by Zeon Corporation of Japan, and the The masterbatch is called masterbatch A, and the nitrile rubbers used are nitrile-18, nitrile-26 and nitrile-40, respectively, and are named in turn: masterbatch B, masterbatch C and masterbatch D.

[0015] component name

[0016] The components in Table 1 are mixed in an internal mixer, and the debinding temperature is controlled at 120-130°C.

Embodiment 1～3 and comparative example 1～9

[0018] The masterbatches A, B, C, and D prepared according to the components listed in Table 1 are mixed and blended in different ways as shown in Table 2 and Table 3, and then mixed with different vulcanization systems and dosages, at 160°C×8min Vulcanization is made into a standard test piece for testing, and the test results obtained are summarized in Table 2 and Table 3.

[0019] Example

[0020] Note 1: In this example, no co-crosslinking aid TAIC was added to masterbatch A and masterbatch C.

Abstract

The invention relates highly damped and oil resistance rubber compound, comprising the following characteristics: using the mixture of polynorbornene rubber and butadiene acrylonitrile rubber as base, using dicumyl peroxide as cross linking agent, and triallyl group isocyanuric esters as auxiliary agent. The content of acrylic nitrile in butadiene acrylonitrile rubber is 23-30úÑ. The weight ratio of polynorbornene rubber and butadiene acrylonitrile rubber is 85-75 / 15-25, preferring to 80 / 20.

Description

technical field [0001] The present invention relates to a rubber composition used for manufacturing shock-absorbing and damping rubber products, in particular to a high-damping oil-resistant rubber composition whose main body is polynorbornene rubber characterized by high damping performance. Background technique [0002] With the continuous improvement of human living standards, people's requirements for the environment are getting higher and higher, and the development of science and technology has prompted the power of machinery and equipment to increase and the speed to speed up. The resulting vibration and noise hazards are becoming more and more serious. It is prominent, that is, in addition to affecting the service life of machinery and equipment and causing early damage to equipment, it will also have a harmful impact on people's work efficiency and physical and mental health. An effective way to deal with this type of vibration and noise is to use high-efficiency dam...
