Embodiment 1

[0024] Put 30 grams of 12-hydroxy lithium stearate and 200 grams of mineral oil into the reactor, stir and heat to 210 ° C, add 480 grams of mineral oil into the reactor, continue stirring, add 250 grams of olefin synthetic oil, and stir. Cool down to 80°C, add 10 grams of butyl octyl primary alkyl zinc dithiophosphate and 30 grams of methyl dibutyl dithiocarbamate, and stir. The composition is oil-pressed three times by a three-roller machine, and then packed in a finished product.

Embodiment 2

[0026] Put 100 grams of 12-hydroxystearic acid lithium complex and 300 grams of ester oil into the reactor, stir and heat to 210 ° C, add 340 grams of ester oil in the reactor, continue stirring, add 200 grams of ester oil, Stir. Cool down to 80°C, add 40 grams of butyl octyl secondary alkyl zinc dithiophosphate, 10 grams of dipentyl methyl dithiocarbamate and 10 grams of basic barium dinonylnaphthalenesulfonate, and stir. The composition is oil-pressed three times by a three-roller machine, and then packed in a finished product.

Embodiment 3

[0028] Put 70 grams of 12-hydroxy lithium stearate and 300 grams of mineral oil into the reactor, stir and heat to 210 ° C, add 200 grams of mineral oil and 180 grams of ester oil into the reactor, continue stirring, and add 200 grams of olefin Synthetic oil, stir. Cool down to 80°C, add 25 grams of butyl octyl primary alkyl zinc dithiophosphate, 20 grams of methyl dibutyl dithiocarbamate and 5 grams of basic barium dinonylnaphthalenesulfonate, and stir. The composition is oil-pressed three times by a three-roller machine, and then packed in a finished product.

Abstract

The invention relates to a lubricating grease composition for a cotton picker and mainly solves the problem that the flowability of lubricating grease is poor in the prior art. The lubricating grease composition provided by the invention comprises the following components in percentage by weight: 3-10% of thickening agent, 84-95% of basic oil with a kinematic viscosity which is 10-100 sq.mm/s anda condensation point which is not higher than 10 DEG C below zero and 2-8% of additive comprising 1-4% of dialkyl phosphorodithioic acid (a), 1-3% of dialkyl aminodithioformic acid (b) and 0-1% of antirust additive (c). The lubricating grease manufactured by the invention has good low-temperature flowability and good pumping performance; the similar viscosity at 30 DEG C below zero is detected byusing an SH/T0048 standard method and numerical values are all less than 200 Pa*S, so that the lubricating grease composition has a certain superiority when being used for the cotton picker.

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, in particular to a cotton picking machine lubricating grease composition. Background technique [0002] Cotton is an important economic crop. With the change of people's ideas and the expansion of cotton planting area, the form of mechanical harvesting of cotton, mainly cotton picker, has been recognized and accepted by more and more people. Mechanical cotton picking can not only greatly reduce labor intensity, but also greatly improve cotton picking efficiency. Cotton pickers can be divided into two categories according to the working principle and structure of the picking parts: horizontal self-propelled cotton pickers with spindles and self-propelled cotton pickers with vertical spindles. Modern cotton pickers are mostly self-propelled large machines with horizontal spindle picking, and the harvesting process is mainly one-time harvesting. The main structure of the cotton picker c...
