Embodiment －

[0045]Feed by mass percentage. Type I base oil is 90.8%, the first additive - high base value synthetic calcium sulfonate is 1.5%, the second additive - high base value sulfurized alkyl phenate calcium is 3.0%, the third additive - polyisobutylene dibutylene Diimide is 1.7%, the fourth additive - thiophosphobutoctyl zinc salt is 1.3%, the fifth additive - aminothioester is 1.0%, the sixth additive - ethylene, propylene and non-conjugated di The terpolymer of olefin is 0.7%, and the seventh additive - polydimethylsiloxane is 0.0002%.

Embodiment 1

[0046] The preparation method of a kind of tillage machine engine and gear box universal lubricating oil described in embodiment one comprises the following steps:

[0047] In the first step, first heat the base oil to 50-60°C, then add the sixth additive ethylene, propylene and non-conjugated diene terpolymer according to the mass percentage and stir evenly to obtain the first mixture;

[0048] In the second step, the first additive high alkali value synthetic calcium sulfonate, the second additive high alkali value sulfurized alkylphenate calcium, the third additive, polyisobutylene bis-succinimide, the Four kinds of additives, thionyl octyl zinc salt and the fifth additive aminothioester are added to the first mixture, and fully stirred to obtain the second mixture;

[0049] The third step is to disperse the seventh additive polydimethylsiloxane in kerosene under stirring according to the percentage by mass. The relative mass ratio of polydimethylsiloxane to kerosene is 1:2...

Embodiment 2

[0054] Feed by mass percentage. Type II base oil is 92.6%, the first additive - high base value synthetic calcium sulfonate is 1.2%, the second additive - high base value sulfurized alkyl phenate calcium is 2.4%, the third additive - polyisobutylene dibutylene Diimide is 1.0%, the fourth additive - thiophosphobutoctyl zinc salt is 1.0%, the fifth additive - aminothioester is 1.0%, the sixth additive - ethylene, propylene and non-conjugated di The terpolymer of olefin is 0.5%, and the seventh additive - polydimethylsiloxane is 0.0001%.

[0055] The preparation method of a kind of tillage machine engine and gear box universal lubricating oil described in embodiment two is the same as embodiment one.

Abstract

The invention relates to all-purpose lubricating oil for a motor and a gear case of a mini-tiller. The all-purpose lubricating oil comprises the following components by mass percent: 89.0-93.6% of base oil and a plurality of additives, wherein the kinematic viscosity of the base oil at 100 DEG C is 15-17mm<2> / s; the first additive is 1.0-2.0% of synthetic calcium sulfonate with high base number; the second additive is 2.0-3.0% of sulfurized calcium alkyl phenol with high base number; the third additive is 1.0-2.0% of polyisobutene bissuccinimide; the fourth additive is 1.0-2.0% of sulfurphosphorousbutyloctyl zinc salt; the fifth additive is 1.0-1.5% of amino monothioester; the sixth additive is 0.2-1.0% of terpolymer of ethylene, propylene and non-conjugated alkadiene, wherein the mooney viscosity (ML(1+4) 100 DEG C) of the sixth additive is 25-35; the seventh additive is 0.0001-0.0002% of polydimethylsiloxane. The invention also relates to a preparation method of the lubricating oil. The all-purpose lubricating oil can be used as the lubricating oil for a gasoline engine and a gear case of a mini-tiller, and also can be used as the lubricating oil for a diesel engine and the gear case of the mini-tiller.

Description

technical field [0001] The invention relates to lubricating oil, in particular to a common lubricating oil for micro tillage machine engines and gear boxes. Background technique [0002] With the development of agricultural modernization, micro tillage machines have developed rapidly in agricultural production in some areas. The tiller is powered by a small diesel engine or a gasoline engine. The power of the main engine is not more than 7.5kW. It adopts an independent transmission system and a walking system. One main engine can be equipped with various agricultural implements. The basic working principle of the tiller is: the engine transmits power to the gearbox through the transmission part, and the gearbox further transmits the power to the drive axle through the meshing of the gears, and the drive axle directly drives the working parts to perform various operations. Therefore, at present, the lubricating oil used in the tiller has three types: gasoline engine oil, die...
