Description
Technical field
The present invention relates to a kind of grease, a kind of lubrication for heavy load open type gear driving system
Fat.
Background technology
Exposed gear is the modal power transmission mode of manufacturing industry, be widely used in electric power, cement, mine,
The main equipment of the industries such as automobile making, iron and steel, chemical industry, papermaking, such as: revolution cellar for storing things, tube mill, sintering
Cellar for storing things, rod mill, coal pulverizer, drying machine, comminutor, drum type pulp kneader, drying oven etc..Large-scale open type tooth
The load ratio of wheel transmission device is relatively big, its effectively, safe operation depend not only on design and the gear institute of gear
Material, more depend on correct assembling, efficient lubricated maintenance and the lubricant of high-quality.According to row
Industry data statistics: except due to design, manufacture, install, operation and maintenance improper outside, gear failure has
Nearly 20% the most more of causes due to insufficient lubrication or lubrication failure.Therefore the effectively lubricating of exposed gear is extremely
Close important.
The Gear shape process precision of exposed gear is relatively low, and roughness is big, and is in heavy duty and company for a long time
Continuous duty, working environment is more severe in addition, is often in big load or has the working condition of impact load,
Gear lubricant lacks sealing protection, and the external agency such as dust, impurity, water is easy to pollute mesh tooth face.
The above brings many adverse influences all to the lubrication of exposed gear, and also opposite opened gear lubricant carries
Go out higher requirement.Good exposed gear lubricating agent should have the antifriction of excellence, spot corrosion wear-resistant, anti-, resist
Extreme pressure property, the most also should possess low toxicity, characteristic tasteless, eco-friendly.
The product of the exposed gear lubricating agent that current domestic manufacturing enterprise is conventional mainly has: asphalitine exposed gear
Oil, refined mineral oil, grease, synthesis type exposed gear oil/grease, gluing lubricant etc..Containing asphalitine
Gear lubricant usually contain a certain amount of volatile solvent, equipment operator and surrounding can be made
One-tenth has a strong impact on, thus it uses and is just limited by more and more.In recent years, with high viscosity mineral oil, conjunction
Oil based on becoming oil to wait, adds extreme pressure anti-wear additives and other additive and the exposed gear oil made also obtains
It is widely applied.The shortcoming of this kind of exposed gear oil is that viscosity is not high enough, easily causes insufficient lubrication, leakage of oil
And excessive spatter, cause environmental pollution and waste.And this series products is in order to ensure the extreme pressure anti-wear of oil product,
Need to add the sulfur-bearing phosphorus extreme pressure anti-wear additives of heavy dose, the extreme pressure anti-wear additives of these sulfur-bearing phosphorus is the most poisonous, have
The chemicals of penetrating odor, easily causes the air of equipment surrounding space and the pollution of environment.The RoHS of European Union
And domestic corresponding regulated substance standard, all lubricating oil is showed the requirement proposing harshness with material, modern
The process of rear waste lubricating oil will become the burden of manufacturer, be lubricant select must faced by problem.
Existing various exposed gear lubricating product, for lowering resistance, reducing consumption, does not also have enough
Reply.The most popular all kinds of open-type gear greases, its power, the energy consumption compared with initially
Colophonium lubricant had significant improvement, but be still significantly improved space.
Open-type gear grease currently on the market is more to use Lubrication Mechanism of Semi-fluid Grease form, and this series products uses
High viscosity base oil, the kollag such as molybdenum bisuphide, graphite and extreme-pressure anti-friction additive are refined to be formed,
Moderate denseness can be kept within the scope of the widest temperature, have excellence adhesion, good antirust ability,
And, even if the most also having stronger water-resistant capacity.A kind of exposed gear grease such as certain disclosure of the invention
Compositions, its base oil is high viscosity artificial oil, and thickening agent is complex calcium sulfonate, is aided with extreme pressure agent, antioxygen
Agent, diluent etc. form.But these class greases are not entirely limited use environmental protection regulated substance, and move
Power loss still has the space improving raising.
Summary of the invention
It is an object of the invention to, on the basis of existing exposed gear grease, for existing product kinetic force
Source comparatively high consumption, the problem containing environmental protection regulated substance in various degree, it is provided that one has good adhesive property
And extreme pressure and antiwear behavior, European Union RoHS2.0 regulated substance requirement can be fully met simultaneously, frictional resistance is bright
The aobvious heavy load open-type gear grease reducing, saving power consumption, to meet development of modern industry to lubrication
Fat requirement.

Described clad aluminum thickening agent is prepared by benzoic acid, C16/C18 fatty acid and the reaction of aluminum isopropylate. trimer, and benzoic acid with C16/C18 fatty acid together, is 1.9:1 with the molar ratio of aluminum in aluminum isopropylate. trimer, and benzoic acid is less than 1 with the molar ratio of fatty acid；
Described graphite particle diameter is less than 5 μm, purity > 99.5%； MoS2Particle diameter is less than 0.6 μm；
Its preparation method, comprises the following steps:
1) first benzoic acid, C16/C18 fatty acid and mineral oil 150BS throwing is stirred to saponification still in formula components ratio, and is warming up to 90 DEG C～95 DEG C；
2) when two kinds of acid stirrings are to when being completely dissolved clarification, the aluminum isopropylate. trimer under room temperature is added；
3) temperature rises to 195 DEG C～200 DEG C, constant temperature 30 minutes；
4) by natural emulsion, polyalphaolefin, poly-methyl-prop
Olefin(e) acid ester is sequentially added in saponification still, stirs 15 minutes；
5) saponification still material is gone in blending kettle, during circulating cooling to 125 DEG C, add borate T361, sulfurized olefin cotton oil T405, liquid octyl group/butyl diphenylamines and N-phenyl-alpha-naphthylamine, stir 15 minutes；
6) when temperature is down to 70 DEG C, in mediation still, sulfur phosphorus fourth pungent primary alkyl zinc salt, benzotriazole, graphite and MoS are added2, stir 15 minutes；
7) blending kettle material is carried out homogenizing, grinds, deaerate, pack.
