[0002] As the automotive industry increases its requirements for engine efficiency and environmental performance, traditional lubricating oil filters have limitations in pollutant adsorption and chemical purification. As vehicles age, the sealing components of automobile engines (such as crankcase ventilation valves, cylinder gaskets, etc.) age and fail, and external moisture or condensed water easily penetrates into the lubrication system and mixes with the engine oil to form an emulsion (emulsification phenomenon). Emulsified engine oil can cause:

[0003] 1. Lubrication failure: Water destroys the strength of the oil film and aggravates metal friction and wear;

[0026] Reference to "embodiment" herein means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The term "embodiment" appearing in various places in the specification does not necessarily refer to the same embodiment, nor does it particularly limit its independence or association with other embodiments. In principle, in the present application, as long as there is no technical contradiction or conflict, the various technical features mentioned in the embodiments can be combined in any way to form a corresponding implementable technical solution.

[0027] Unless otherwise defined, the technical terms used in this document have the same meanings as those generally understood by those skilled in the art to which this application belongs; the use of relevant terms in this document is only for describing specific embodiments and is not intended to limit this application.

[0028] In the description of this application, the term "and / or" is an expression used to describe the logical relationship between objects, indicating that three relationships may exist, for example, A and / or B, which means: A exists, B exists, and A and B exist at the same time. In addition, the character " / " in this article generally indicates that the objects before and after are in an "or" logical relationship.

[0029] In the present application, terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship of quantity, priority or sequence between these entities or operations.

[0030] Without further limitations, in this application, the words "include", "comprises", "has" or other similar expressions used in the sentences are intended to cover non-exclusive inclusion. These expressions do not exclude the presence of additional elements in the process, method or product including the elements, so that the process, method or product including a series of elements may include not only those limited elements, but also other elements not explicitly listed, or also include elements inherent to such process, method or product.

[0031] Similar to the understanding in the Examination Guidelines, in this application, expressions such as "greater than", "less than", "exceed" and the like are understood to exclude the number itself; expressions such as "above", "below", "within" and the like are understood to include the number itself. In addition, in the description of the embodiments of this application, "multiple" means more than two (including two), and similar expressions related to "multiple" are also understood in this way, such as "multiple groups", "multiple times", etc., unless otherwise clearly and specifically limited.

[0032] The first aspect of the present application provides an energy-saving and high-efficiency vehicle filter element, wherein the material of the energy-saving and high-efficiency vehicle filter element includes a specific surface area of ​​2000m 2 / g porous activated carbon, rare earth element oxides, mesoporous nano titanium dioxide, nano manganese dioxide, diatomaceous earth, bentonite and zirconium oxide; the rare earth elements include cerium and lanthanum.

[0033] The porous structure of activated carbon (surface area>2000m 2 / g) can capture the colloid, carbon precursors and tiny particles generated by oil oxidation, inhibit the formation of sludge; keep the oil path unobstructed, and reduce the friction resistance between the piston ring and the cylinder wall. In addition, activated carbon also absorbs free water in the lubricating oil, reduces the humidity of the oil, and delays the emulsification process of the lubricating oil.

[0034] The oxygen atoms in rare earth oxides tend to attract electrons, forming O 2- , while rare earth cations show strong electron-donating ability, making the surface alkaline. The surface of rare earth oxides easily absorbs water molecules, which dissociate on the surface to form hydroxyl groups (OH - ) and protons (H+). There are a large number of basic sites on the surface of rare earth oxides, which can adsorb acidic gases (such as CO2, SO2) or acidic molecules (such as carboxylic acids and phenols) and react with them.

[0035] Rare earth oxides decompose sulfides and nitrogen oxides in engine oil, inhibit sludge formation, and ensure long-term cleanliness of the lubrication system. The alkaline surface of rare earth materials can neutralize acidic byproducts (such as sulfuric acid and nitric acid) in engine oil, prevent corrosion of bearings and gear surfaces, maintain smooth contact surfaces, and reduce friction coefficients.

[0036] Rare earth oxides catalyze the reaction of water and polar substances (such as detergents) in engine oil at high temperatures, causing the emulsion to break and stratify, restoring the oil-water separation state. The alkaline surface of rare earth oxides can neutralize sulfuric acid and nitric acid generated by the reaction of water and sulfur oxides, control the total acid value (TAN) of lubricating oil within a safe range (<2mg KOH / g), and protect the engine, bearings, and gears from corrosion. The rare earth ions obtained after neutralization also have antioxidant function, blocking the free radical chain reaction through the electron transfer mechanism, and extending the oxidation induction period of engine oil by more than 50%.

[0037] Different from the prior art, the above technical solution provides an energy-saving and efficiency-enhancing vehicle filter element, a porous structure of activated carbon (specific surface area> 2000m 2 / g) will absorb impurity particles and free water in the lubricating oil, reduce the humidity of the oil and delay the emulsification process; rare earth oxides can decompose the emulsified lubricating oil, promote the emulsion demulsification and stratification, and restore the oil-water separation state; at the same time, it can adjust the total acid value of the lubricating oil and play a role in protecting the engine.

[0038] Furthermore, the specific surface area of ​​activated carbon is >2000m 2 / g, preferably 2500-3000m 2 / g, pore size 2-50nm. Activated carbon can grade and adsorb pollutants of different sizes through micropores (<2nm), mesopores (2-50nm) and macropores (>50nm). Mesopore activated carbon (2-50nm) is preferred mainly because it adsorbs most of the soot particles, metal debris and colloidal precipitates in lubricating oil.

[0039] Furthermore, the rare earth element oxide includes cerium oxide and lanthanum oxide, and the mass ratio of cerium oxide to lanthanum oxide is 3-5:1.

[0040] Furthermore, the mass ratio of the porous activated carbon, rare earth element oxide, mesoporous nano titanium dioxide, nano manganese dioxide, diatomaceous earth, bentonite and zirconium oxide is 30-40:6-10:4-8:3-5:2-8:2-4:3-5.

[0041] Furthermore, the filter element material is auxiliary bonded with 0.2-0.5wt% modified epoxy resin adhesive. The modified epoxy resin adhesive has high temperature resistance and is suitable for the working environment of automotive lubricating oil.

[0045] S3: putting the first mixed powder and the second mixed powder into a high-speed mixer and stirring at a speed of 600-800 r / min for 20-30 min to obtain a mixture;

[0046] S4: Pressing the mixture into a mold at a pressure of 10-15 MPa for 5-10 minutes, and sintering at 200-300° C. to obtain the energy-saving and efficiency-enhancing vehicle filter element.

[0047] Sintered at 200-300℃ in air, the surface of the material easily absorbs oxygen and water molecules to form hydroxyl groups, forming an alkaline surface, which neutralizes the lubricating oil with acid.

[0048] Furthermore, in the step S2, the calcination temperature is 300-400°C.

[0049] Furthermore, in the step S3, 0.2-0.5 wt % of modified epoxy resin glue is added while stirring.

[0051] Among them, the wire mesh covered non-woven fabric structure can effectively intercept particles >20μm and increase the service life of the filter element.

[0052] Furthermore, the mass ratio of the porous activated carbon, rare earth element oxide, mesoporous nano titanium dioxide, nano manganese dioxide, diatomaceous earth, bentonite and zirconium oxide is 30-40:6-10:4-8:3-5:2-8:2-4:3-5.

[0054] The fourth aspect of the present application also provides a vehicle lubricating oil filter, which adopts the energy-saving and efficiency-enhancing vehicle filter element described in the first aspect of the present application and the third aspect of the present application.

[0055] Different from the prior art, the automotive lubricating oil filter of the present application not only adsorbs small particles in the lubricating oil, but also adsorbs moisture and oxidation products in the lubricating oil to ensure the stability of the lubricating oil viscosity, form a uniform and strong oil film, reduce direct contact between metal parts, and thus reduce energy loss.
