Galling, metallic corrosion, metal fatigue are the three big reasons that cause mechanical means to damage, internal authority mechanism statistics is thought " metallic substance three lossies account for gross industrial output value 30% ", the financial loss that the depreciation that produces because of the mechanical transmission frictional wear, maintenance, maintaining etc. cause be equivalent at present (?) Chinese whole GDP 10%.
According to " the national coasting port allocation plan " of the up-to-date promulgation of the Ministry of Communications, the Chinese Port construction is the Eleventh Five-Year Plan period entering great-leap-forward development period, and to 2010, the coasting port handling capacity reached 3,000,000,000 tons.But the coastal natural deep water coastline resource of China is in short supply at present, and the port and harbour construction room for development is little, and deep-cutting to build the berth or build man-made island on the shoal becomes a megatrend.Following 10 years or be the peak time of coastal area of china harbor approach enlarging more over a long time, from current coasting port planning and engineering progress, the dredging engineering amount was the gesture of further expansion.According to incompletely statistics, to 2010, the coastal area of china principal port needed to carry out the navigation channel with trailing suction hopper dredger and opens up the year capital construction of dark and port engineering and safeguard that the dredging amount is at 1.8～2 billion cubic meters.
Snagboat is mainly used in the sea of blowing at harbour and builds up fields and build and the waterway dredging engineering.Each busy harbour in the world, the snagboat of multiple shape on the job is digging water channel and rivers and creeks clearly, so that other boats and ships pass through smoothly.Along with China becomes world's major trading nation, the port construction development rapidly, the snagboat business spreads all over the country coastal and the inner hargour, the economic worth that its day creates is huge, created 1,000,000 yuan of the output values in average day, the whole nation has 400 snagboats that moving approximately, and an average snagboat year consumes 40 tons of lubricating oil, 6000 tons of oil fuel belong to high oil consumption, high profit industry.Past, the manufacturing of snagboat is mainly monopolized by American-European developed country, cost is very expensive, raising along with domestic shipbuilding technology, the Made in China shipyard is by the import, digestion and absorption technology, grasped the construction of snagboat gradually, but because the limitation of manufacturing process and material, no matter homemade snagboat core component-engine is in manufacturing technology level, still on the material horizontal, external gap is bigger, and itself belongs to high energy consumption snagboat, excessive risk, high profit, and it is heavy to be in load, move in the working condition bad working environment, although used the conventional lubrication oil production (as shell, Mobil, Great Wall, the Kunlun etc.), but because of conventional lubrication oil can't fundamentally change the defective of engine material itself, therefore, outstanding subject matter is embodied in: engine noise and vibration are bigger, serious wear, power output is relatively poor, and oil consumption is big, and maintenance is frequent, seriously reduce working efficiency, influenced economic benefit of enterprises.
Adding the performance that suitable anti-wear agent improves lubricating oil in lubricating oil is one of main path that addresses the above problem.Have the bibliographical information of ceramal lubricating oil additive research aspect at present both at home and abroad, for example, Chinese invention patent publication number CN1346873 discloses a kind of lubricating oil additive of based on cermet lubrication mechanism, it consists of the compound that contains molybdenum, boron, sulphur, phosphorus etc., though this additive has abrasion resistance preferably, it contains objectionable impuritiess such as a large amount of sulphur and phosphorus.Chinese invention patent publication number CN1765803 discloses a kind of metal/ceramic nano composite additive of self-rehabilitation and preparation method thereof, belong to the nanoparticle suspension technology, in addition, Chinese invention patent publication number CN101186856 discloses a kind of be used for lubricating oil nano-stage ceramic metal additive and preparation; Chinese invention patent publication number CN1324922 discloses a kind of sintering metal lubricant and manufacture method thereof, this lubricant is made up of 5～15% slip additive and 85～95% carrier fluid, wherein slip additive is to be formed by Nano metal powder, nano-ceramic powder and dispersion agent uniform mixing, therefore these three kinds of methods all remain further to be improved because the dispersion technology of nanoparticle in lubricating oil remains in big defective.U.S. Pat 4,844,825 disclose a kind of extreme-pressure additive based on the chlorination petroleum wax, can effectively improve the lubricated anti-friction performance of oil engine, but in and the metallic corrosion that causes of muriate, must add a large amount of alkaline sulfonates, make sulphur content can't be lower than 1%.U.S. Pat 7,423,000 discloses a kind of extreme-pressure additive of not phosphorous and metallic compound, but can't use the sulfur-bearing additive with avoiding.U.S. Pat 6,588,393 disclose the metal tripolyphosphate compound extreme-pressure additive of a kind of low sulfur content (5-250ppm), though sulphur content is extremely low, phosphorus content can't reach GF-4, the GF-5 standard.
Though what added above-mentioned additive in lubricating oil can reach anti-wear effect, the shortcoming that above-mentioned additive itself exists makes lubricating oil not reach national standard behind the adding lubricating oil, such as, easily precipitate, perishable, sulphur and phosphorus content are high.
Snagboat itself belongs to high energy consumption, excessive risk, high profit, and being in again in load weight, the working condition bad working environment and moving, although used conventional lubrication oil production (as shell, Mobil, Great Wall, the Kunlun etc.), but can't fundamentally change the defective of engine material itself because of conventional lubrication oil, therefore, outstanding subject matter is embodied in: engine noise and vibration are bigger, serious wear, power output is relatively poor, oil consumption is big, maintenance is frequent, has seriously reduced working efficiency, influences economic benefit of enterprises.
