Abstract

The invention belongs to the field of chemistry and relates to long-acting antirust grease and a preparation method thereof. The long-acting antirust grease mainly comprises the following components ( by weight): 70 to 90 parts of base oil, 3 to 6 parts of thickening agent, 4.5 to 8 parts of antirust additive, 4 to 8 parts of film-forming agent, 0.5 to 1 part of antioxidant, and 3 to 6 parts of assistant. The antirust grease has the characteristics that: the application of the grease is easy; the durability is high; the detachment of fasteners at next time is easy; the application range is wide; and the like. The long-acting antirust grease is suitable for outdoor steel fasteners which require anti-corrosion treatment and cannot be coated with paint.

Description

Technical field: [0001] The invention belongs to the field of chemical industry and relates to long-acting antirust oil and a preparation method thereof. Background technique: [0002] Outdoor steel fasteners involve railway rail fastening bolts, bridge telescopic parts, fastening bolts and parts, mining machinery fastening bolts and parts, oil field fastener bolts and parts, etc. These application places are often exposed to the outdoors, exposed to the sun, rain, hot summer and cold winter, and the working conditions are very harsh. Due to frequent disassembly and maintenance, and they cannot be painted for corrosion protection, they must be coated with anti-rust grease to reduce corrosion and prolong service life. [0003] In the past, waste engine oil was often used to brush. The surface material cost is very low, but the durability is poor, the frequency of brushing is high, the labor cost is high, the rust resistance is poor, and the pollution is large. With the impro...
