Problems solved by technology

[0003] At present, the lubricating grease used in the field of ceramic fiber production is mostly block solid paraffin, which needs to be heated and dissolved with kerosene, and then poured into 70°C water to make the required lubricating grease emulsion. The preparation process is cumbersome, and the lubricating effect is excellent. Poor resistance, high ignition point

Abstract

The invention provides ceramic fiber lubricating grease which comprises 50wt%-80wt% of a lubricant, 10wt%-40wt% of a softening agent and 0wt%-30wt% of kerosene. The ceramic fiber lubricating grease provided by the invention is prepared by mixing the lubricant, the softening agent and the kerosene, wherein the preparation process is simple, the lubricant is mainly used for softening fibers and also partially used for lubricating the fibers; the softening agent is a water-soluble lubricant which is used for lubricating and needling fibers, and can also be used for improving the water solubility of the novel lubricating grease system. The lubricant, the softening agent and the kerosene act with one another, so that the ignition point of the ceramic fiber lubricating grease can be lowered. Moreover, the ceramic fiber lubricating grease provided by the invention is easy to atomize, and relatively uniform to apply while being applied to a ceramic fiber needled felt.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a ceramic fiber lubricating grease. Background technique [0002] Ceramic fiber is a kind of ultra-light, flexible, low thermal conductivity, high temperature resistant fibrous material obtained by fiberizing ceramic materials. It is widely used in industrial kilns, metallurgy, petrochemical and other fields. The ceramic fiber is needle-punched into a blanket-like product to prepare a ceramic fiber blanket, which expands the application field of the ceramic fiber and improves its use effect. Although ceramic fiber is a flexible ceramic material, the inherent brittleness of ceramics makes it subject to mechanical impact during needle punching, causing problems such as fracture and crushing. Therefore, in the production process of ceramic fiber needle punched blankets, it is necessary to apply process Grease solution, so as to further soften the fiber, reduce the fri...
