Description
Technical Field
The invention belongs to the high-temperature lubricating grease industry, and particularly relates to high-temperature non-carbonized antiwear paste.
Background
In the prior art, the commonly used high-temperature lubricating grease is mainly prepared by thickening and synthesizing a base oil by thickening agents such as a composite lithium-based soap, a composite aluminum soap, a composite calcium sulfonate soap, organic polyurea, inorganic bentonite, inorganic siliceous materials and the like, and adding an antioxidant, an antiwear extreme pressure agent and the like. The metal soap-based thickener is a catalyst at high temperature, can accelerate the oxidative deterioration of oil products, is easy to decompose when the organic thickener is determined by the properties of the organic thickener and is easy to carbonize at high temperature, and is ineffective when the inorganic thickener is at high temperature. Synthetic base oils such as PAO, ester oil and the like are easy to oxidize and deteriorate at the temperature of more than 300 ℃ and under the action of a thickening agent, so that the lubricating effect is poor. The use temperature of the existing high-temperature grease is generally not more than 350 ℃ due to the reasons. The temperature of the slide position, the inclined top position, the push plate and the thimble position of an injection molding machine and a die-casting die in industry is usually far more than 350 ℃, and the lubricating agent is required not to be carbonized and blackened and not to pollute the position, but the high-temperature lubricating grease commonly used at present obviously cannot meet the requirements.
Disclosure of Invention
In view of the above, the invention provides a high-temperature non-carbonized antiwear paste, which overcomes the defects of the high-temperature lubricating grease and develops the high-temperature non-carbonized antiwear paste with the temperature resistance up to 1400 ℃.
The technical scheme of the invention is as follows:
the high-temperature non-carbonization antiwear paste is characterized by comprising the following components in parts by weight: base oil 200-375 parts, medium-high temperature lubricant 5-10 parts, high temperature lubricant 50-125 parts, ultra-high temperature lubricant 50-125 parts, antioxidant 1.5-5 parts, and antirust 2.5-5 parts; the base oil is high-viscosity polyether oil, and the high-temperature lubricant is boron nitride.
Further, the high-temperature non-carbonized antiwear paste comprises the following components in parts by weight: 300 parts of base oil 250-containing organic solvent, 6.2-8 parts of medium-high temperature lubricant, 65-100 parts of ultra-high temperature lubricant, 2-4 parts of antioxidant and 3-4 parts of antirust agent; the base oil is high-viscosity polyether oil, and the high-temperature lubricant is boron nitride.
Further, the kinematic viscosity of the base oil at 40 ℃ is 500-10000mm2/s。
Furthermore, the fineness of the boron nitride is 1-10 microns.
The polyether is prepared from raw materials such as ethylene oxide, propylene oxide, butylene oxide and the like through ring-opening homopolymerization or copolymerization and can be divided into water-soluble polyether, water-insoluble polyether and oil-soluble polyether. The polyether has many excellent properties, such as very high viscosity index, excellent lubricating property, high flash point, low pour point, wider working temperature range, better compatibility to rubber parts, very low toxicity, less carbon residue, complete volatilization at high temperature and no residue. Because the molecular structure can be customized and the molecular weight can be large or small, different polyethers can be prepared to meet different use requirements. Can be applied to gear oil, worm and gear oil, brake fluid and the like. When the temperature is lower than 350 ℃, the oil-soluble polyether adopted by the invention has excellent extreme pressure lubricating property at relatively low temperature, and can be completely volatilized without carbonization and residue at higher temperature.
In addition, the boron nitride adopted in the invention belongs to a hexagonal system, is a ceramic material, has the heat stability of 700 ℃ in air, the maximum use temperature of 900 ℃ in an oxidizing atmosphere and 2800 ℃ in an inactive reducing atmosphere, but has poor lubricating property at normal temperature, and when the temperature is lower than 500 ℃, the organic molybdenum, the base oil and the like have the lubricating protection effect, but the temperature is higher than 500 ℃, the boron nitride starts to play the lubricating effect, and the friction coefficient can reach 0.01.
Further, the medium-high temperature lubricant is organic molybdenum.
Furthermore, the fineness of the organic molybdenum is 10-50 microns.
The organic molybdenum lubricant adopted in the invention can play a good lubricating role at medium and high temperature (between 350 ℃ and 500 ℃), and can be completely sublimated and decomposed without residue after exceeding 500 ℃.
Further, the ultra-high temperature lubricant is one or more of nano aluminum oxide, nano zinc oxide, nano silicon dioxide, nano titanium oxide, nano calcium carbonate, nano copper borate, nano calcium borate and nano titanium borate.
Further, the fineness of the ultra-high temperature lubricant is 10-50 nanometers.
Nanomaterials are materials that have at least one dimension in three dimensions in the nanometer range (0.1-100 nm) or are composed of them as elementary units, which corresponds approximately to the scale where 10-100 atoms are closely arranged together. The mechanism of lubrication of the nano lubricating material can be understood as follows: the nano material is mostly of a spherical structure, and the lubricating property is good; under the condition of high temperature, the spherical particles are flattened to form a metal-metal sliding system, so that the extreme pressure wear resistance is excellent; the nanometer particles can play a role in automatic repair; the compounding of the composite nano material can play a synergistic role. The nano material used in the invention has high temperature resistance of more than 1500 ℃ without failure, and keeps good yellowing resistance.
Further, the antioxidant is one or more of L57, L135, T501 and DSTP.
Further, the antirust agent is one or more of T701, T705, T746, T703 and T711.
The antioxidant and the antirust agent adopted by the invention are all general products in the prior art, and are mainly used for protecting the service life of an oil product at a lower temperature and ensuring long-term effective performance of lubrication.
The preparation method comprises the following steps: the materials are mixed according to the parts by weight, stirred and mixed uniformly by a motor, and then ground for 3 times by a three-roll grinder, and the product is obtained after the material fineness is required to be less than 10 microns.
The high-temperature lubricating grease disclosed by the invention has the advantages that the polyether oil is selected as the base oil, the lubricating performance is excellent at low temperature, the lubricating grease can be completely free of carbonization and residue at high temperature, then the high-temperature lubricating grease is matched with lubricants in different high-temperature sections, the high-temperature performance of the high-temperature lubricating grease can be as high as 1400 ℃, the problem of carbonization and coking of the existing high-temperature lubricating grease at ultrahigh temperature is well solved, the high-temperature lubricating grease can be widely applied to the slide position, the inclined top position, the push plate, the thimble position and the like of an injection molding machine and a die-casting die, the temperature of the slide position, the inclined top.
