Embodiment 1

[0010] The invention is a novel pressure-resistant gear oil, which is made of the following raw materials in parts by weight:

[0011] 5.6 parts of silicone modified dimer acid, 3.2 parts of borax, 2.9 parts of sodium naphthenate, 3.2 parts of modified sodium phosphate, 4.4 parts of diethanolamine boric acid polyhydroxy acid and 1.8 parts of isothiazolinone.

Embodiment 2

[0013] The invention is a novel pressure-resistant gear oil, which is made of the following raw materials in parts by weight:

[0014] 2.5 parts of silicone modified dimer acid, 2.5 parts of borax, 1.5 parts of sodium naphthenate, 2.5 parts of modified sodium phosphate, 2.5 parts of diethanolamine boric acid polyhydroxy acid and 1.5 parts of isothiazolinone.

Embodiment 3

[0016] The invention is a novel pressure-resistant gear oil, which is made of the following raw materials in parts by weight:

[0017] 7.4 parts of silicone modified dimer acid, 4.4 parts of borax, 4.7 parts of sodium naphthenate, 4.7 parts of modified sodium phosphate, 4.6 parts of diethanolamine boric acid polyhydroxy acid and 2.6 parts of isothiazolinone.

[0018] Compared with the existing gear oil, the present invention adopts high-quality base oil and new environment-friendly gear oil additive compound, which not only greatly improves the load-carrying capacity of the gear oil, but also eliminates the health impact caused by the traditional lead-containing formula on the operators. And can effectively prevent the wear and tear on the surface of steel and copper parts; proper adhesion and extremely low friction coefficient can effectively reduce the noise generated by the gear during operation and the body temperature, reduce energy consumption, prolong the life of the gea...

Abstract

The invention discloses a novel compression-resistant gear oil, which is prepared from the following raw materials by weight: 2.5-7.4 parts of organosilicon modified dimeric acid, 2.5-4.4 parts of borax, 1.5-4.7 parts of sodium naphthenate, 2.5-4.7 parts of modified sodium phosphate, 2.5-4.6 parts of diethanolamine boric acid poly hydroxy acid and 1.5-2.6 parts of isothiazolinone. Compared with the existing gear oil, the compression-resistant gear oil provided by the invention uses high-quality base oil and novel environment-friendly gear oil additives, not only improves bearing capacity of the gear oil but also eliminates influences of a traditional lead-containing formula on health of the operators, and can effectively prevent the surface wear of steel and copper parts. Proper adhesion and extremely low friction coefficient can effectively reduce the noise produced by the operation of the gear and the body temperature, reduce energy consumption, prolong the service life of the gear, greatly prolong the service life of oil, reduce the oil change frequency and save cost for the enterprises.

Description

technical field [0001] The invention relates to a novel anti-pressure gear oil, which belongs to the field of industrial chemical industry. Background technique [0002] Gear oils are used to reduce wear between moving parts where there is metal-to-metal contact and to remove heat from the parts. Gear oils usually contain high-viscosity base stocks and various additives to improve wear, friction coefficient, oxidation resistance, etc. Automotive gear applications are typically formulated with base oils having a viscosity of about 30 cSt or higher at 100°C and a viscosity index greater than about 80, referred to as refined high viscosity gear oil formulations. Such base oils are particularly suitable for gear applications due to their ability to remain clear and maintain suitable viscometric properties under extreme operating conditions. However, the availability of base oils can become limited or expensive. Accordingly, there is a need for gear oil formulations that can b...
