Nano titanium dioxide-type damping grease composition

Abstract

The invention relates to the field of damping materials, and more particularly, provides a nano titanium dioxide-type damping grease composition, which comprises, in parts by weight: (A) 100.0 parts of polysiloxane synthetic base oil, (B) 5.0 to 50.0 parts of nano titanium dioxide, (C) 0.5 to 5.0 parts of modified surface treatment agent, (D) 1.0 to 10.0 parts of torsional force intensifier, (E) 3.0 to 10.0 parts of solid lubricant, and (F) 0.2 to 2.0 parts of antioxidant corrosion inhibitor. The finished damping grease prepared by these materials in the above proportions has excellent high / low temperature performance, wide applicable temperature range and high shear stability, is capable of controlling motion accurately and reducing noise, and can be widely applied to any part of a variety of optical instruments, electronic instruments, measurement instruments and the like, which requires the control for free motion. Meanwhile, the production process is simple and easily implementable, so the nano titanium dioxide-type damping grease composition is suitable for large-scale batch production.

Description

technical field

[0001] The invention belongs to the field of damping lubricating materials, and in particular provides a nano-titanium dioxide type damping grease composition. Background technique

[0002] The damping structure refers to the structure that combines the damping material and the component to consume the vibration. 目前,有关阻尼结构的文献报道较多,如中国专利CN201110104841.3、CN201020180385.1、CN200920183597.2、CN200920181534.3、CN200920135526.5、CN200920021859.5、CN200710200751.8、CN200610049632.2、CN200510010111.1、 CN200420048936.3, CN94215977.2, CN201010596292.1, etc. However, there are few reports on the development of damping materials, but in many fields, there is a great demand for high-quality damping structures (damping materials). In some occasions, it is necessary to use a damping structure to reduce the hazards caused by mechanical vibration and noise, and in some occasions it is necessary to use a damping structure to precisely control the action, and some electronic products ...
