Problems solved by technology

However, in some special occasions, the application of mineral base oils is limited, at this time it is necessary to use synthetic base oils and bio-oil base oil products
[0004] At present, there are various lubricating oils on the market, but these lubricating oils are not complete in function. Some lubricants with good anti-wear effects cannot adapt to high-temperature environments. For example, when a car is running, auto parts are often at high temperatures At this time, ordinary lubricating oil cannot exert its due lubricating effect; and some lubricating oils with good temperature resistance also have insufficient anti-friction, so how to develop a kind of lubricating oil that is resistant to friction and can adapt to higher temperature environments The lubricating oil becomes the key of the present invention's research

Abstract

The invention discloses heat-resisting anti-wear lubricating oil. The lubricating oil is prepared from, by weight, 50-70 parts of base oil, 10-14 parts of allyl isothiocyanate, 6-10 parts of C thiamine pyrimidine, 4-8 parts of 3-thiophenecarboxaldehyde, 3-7 parts of 2-nitro-4-chlorophenol, 2-5 parts of 2-amino-6-chlorobenzothiazole, 9-13 parts of a perfluoroethylene propylene copolymer, 6-12 parts of fumaric acid resin, 10-13 parts of 2-methyl-2-propanethio, 10-20 parts of acetylsalicylic acid, 8-13 parts of diethylene glycol ether and 5-9 parts of 5-methyl-3-hexanone. The lubricating oil has both the good heat resistance and friction resistance by adopting various chemical substances for modifying the base oil.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to a heat-resistant and anti-wear lubricating oil and a preparation method thereof. Background technique [0002] Wear is the friction between the kinematic pairs, which leads to the gradual loss or migration of the surface material of the part. Friction and wear phenomena are ubiquitous in natural phenomena and can be seen everywhere around us. Lubricating oil is mainly used in various types of automobiles and mechanical equipment. It can reduce friction, play an auxiliary role in cooling, rust prevention, cleaning, sealing and buffering, etc. to protect machinery and processed parts. Its invention can better solve the problem of friction and wear. [0003] Lubricating oil generally consists of two parts: base oil and additives. The main component of lubricating oil is base oil, which determines the most basic properties of lubricating oil; the addition of additives can ...
