Lubricating grease composition for concrete pump truck and preparation method of lubricating grease composition

Abstract

The invention relates to lubricating grease composition for a concrete pump truck and a preparation method of the lubricating grease composition. The lubricating grease composition is prepared from 30%-40% of No.3 lithium-based lubricating grease, 60%-70% of base oil, 1%-5% of an additional solid antifriction agent and 1%-2% of an antirust agent. The No.3 lithium-based lubricating grease is added to a reaction kettle, the base oil in a formula ratio is added and stirred, and the mixed materials are heated to 70-90 DEG C; the calculated quantity of the antifriction agent and the antirust agent are added, stirring is continued for 40-60 min, and a finished grease product is obtained through oil rolling for two or three times. With the selection of the base oil and a thickening agent with good compatibility as well as an appropriate raw material ratio, the lubricating grease composition has good lubricating property. The price of a product made of the raw materials is appropriate, a cost-performance ratio of the product formed through processing is high, and the product has better market value. According to the preparation method, the common reaction kettle is adopted, special equipment is not needed, one-step direct reaction is adopted for refining, the process is simple, energy consumption and production cost are reduced, and besides, the quality of the product produced with the process is relatively stable.

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, in particular to a composition and a preparation method of lubricating grease for concrete pumping vehicles. Background technique [0002] Concrete pumping truck is used to transport concrete to the designated location on site for pouring. It is an indispensable equipment in the construction process of high-rise buildings, underground buildings and large buildings. It has fast speed, stable quality and low labor intensity in the construction process, and it is an indispensable construction machine in modern buildings. It is one of the conditions to ensure the smooth progress of the project to use grease with the concrete pump truck to ensure the efficient operation of the pump truck and reduce the downtime and maintenance time during the work process. At present, there are many kinds of lubricating grease for concrete pumping vehicles. Lithium base grease No. 0 and No. 00, extreme pre...

Problems solved by technology

At present, there are many kinds of lubricating grease for concrete pumping vehicles. Lithium base grease No. 0 and No. 00, extreme pressure lithium base grease No. 0 and No. 00, and semi-fluid extreme pressure lithium complex. The various lubricating greases used are as follows: Some contain additives, some do not contain additives, some types of additive systems are compatible, and some are not compatible; because it is impossible to use only one supplier for purchasing raw materials, it will be determined according to the delivery period, product quality, Price constraints lead to the diversification of its varieties purchased, and often multiple varieties are piled together in the warehouse, so the cross-use of different greases will inevitably occur during use, and frequent replacement of grease will lead to lubrication failure resulting in equipment downtime
