ている。[0003] In the automobile industry, general passenger cars have been reduced in size and weight, and with the adoption of FFs, constant velocity joints (Constant Velocity Join) have been developed.
Vehicles that use CVJs (hereinafter, abbreviated as CVJ) are increasing. The demand for CVJs has also been increasing in 4WD vehicles and 4-wheel independent suspension FR vehicles. CVJ is
Also known as a constant velocity universal joint, it is a joint that transmits rotation while maintaining the same angular velocity and torque, and has various types. The lubricant used depends on the purpose of use, but with the recent increase in the output and speed of automobiles and the weight reduction of the CVJ itself, it has become even more severe, and greases that reduce friction and wear of sliding parts have been developed. Required. Also,
It is necessary to attach a seal boot material to CVJ to prevent grease from leaking and to prevent foreign substances and water from entering. As this material, chloroprene rubber is most commonly used, but polyester resin is also used. Many are used.

Although the durability of the seal boot material can be improved due to its temperature suppressing effect, an excessive rise in temperature promotes the aging of the seal boot material and the deterioration of the lubricant, and significantly impairs the life of the CVJ.

ある。[0005] On the other hand, in the steel industry, continuity of machinery and equipment has been further promoted along with technological innovation, and there is a strong demand for higher quality of products, improvement of production process capability, assurance of equipment reliability, and the like. The grease used in these machinery and equipment is under adverse environments such as high heat, contact with water, and the possibility of foreign matter intrusion such as scales. Very strict. In order to prolong the life of mechanical parts and prevent catastrophic failures,
There is a demand for a grease that reduces abrasion and has excellent sealing resistance. In addition, lubrication points of industrial machines, machine tools, and the like have high friction and wear progresses, and the precision of the machine decreases, so that machine parts must be replaced. Thus, reducing friction and preventing wear are also important issues in this application.

ている。[Evaluation] The friction coefficients of Examples 1 to 7 were all smaller than those of Comparative Examples 1 to 10, and good results were obtained. With respect to the abrasion resistance, Comparative Examples 5, 6, 7, 9 and 10 give the same good results as the examples. However, these comparative examples are inferior in compatibility with chloroprene rubber or polyester resin. For example, in Comparative Example 5, the chloroprene rubber and the polyester resin have large elongation change rates. In Comparative Example 6, the tensile strength and elongation change of the chloroprene rubber were large. In Comparative Example 7, the tensile strength and elongation change of the chloroprene rubber and the polyester resin are remarkably large. In Comparative Examples 9 and 10, the rate of change in elongation of the polyester resin was slightly large. It is clear that Examples 1 to 7 are excellent in friction coefficient and abrasion resistance, and also excellent in compatibility with chloroprene rubber and polyester resin sealing materials. In addition, Comparative Examples 1 to 3 contain one of the additives of the present invention, and thus show some very good results in terms of the rate of change, but are inferior in terms of friction coefficient and abrasion resistance.

装置のシール材の劣化を遅延する。(1) The grease of the present invention has a low coefficient of friction and excellent wear resistance. As a result, vibration and noise of the constant velocity joint of the vehicle are suppressed. In addition, wear of ball joints, wheel bearings and other industrial machinery of automobiles can be reduced, and the life of mechanical parts can be improved. (2) The grease of the present invention has excellent compatibility with chloroprene rubber and polyester resin, and delays the deterioration of the sealing material of the sealing device even at high temperatures.
