Abstract

The invention discloses water conservancy engineering food grade steel wire rope surface lubricating grease comprising the following raw materials: 85-94% of base oil, 6-15% of a thickener and anti rust agent with the weight of 0.5-20% of the total weight of the base oil and the thickener; the base oil comprises food grade mineral oil, synthetic oil or mixed oil of the food grade mineral oil and the synthetic oil, the 100 DEG C kinematic viscosity of the base oil is 10-100mm<2> / s; the thickener comprises C16-C20 long-chain fatty acids, aromatic acids and organic aluminum compounds in the molar ratio of 1:1-1.7:1-1.2. The water conservancy engineering food grade steel wire rope surface lubricating grease meets the health and safety standards of drinking water industry, may not cause pollution of drinking water sources, has good water resistance, does not decompose in the water, has less oil bloom and good antirust property, and can effectively protect the surface of a steel wire rope.

Description

technical field [0001] The invention relates to a food-grade lubricating grease, more precisely, a lubricating grease applied to the surface of food-grade steel wire ropes in water conservancy projects, a preparation method and application thereof. Background technique [0002] Water conservancy projects are generally built against rivers or along rivers. This feature determines that their development activities have a more direct impact on the local water environment, especially during the construction period. At present, the lubricating grease used on the wire rope of hoist in water conservancy projects is industrial grade, which contains heavy metals and carcinogens. The lubricating grease on the wire rope is mostly filled by manual application. During the working process of the wire rope, the excess grease attached to the rope body will fall into the water, causing local and downstream water environmental pollution, and causing harm to the lives of downstream residents a...
