Nano borate engine oil

Abstract

The invention discloses nano borate engine oil and belongs to the technical field of engine oil formulas. The nano borate engine oil is prepared from API II type base oil, a molybdenised abrasion-resistant and energy-saving agent, alkylphenol, cetyl calcium borate, nano cerium borate, a defoaming agent, a clearing agent, N,N-dimethylformamide, an ashless dispersing agent, hydroxy stearate, dimeticone, sulfonate, a succinimide dispersing agent, talcum powder, amine antioxidant, ethylene glycol butyl ether, a viscosity index improver, molybdenum disulfide, graphite powder, mono-succinimide, sorbitan monooleate, petroleum ether, chloroform, friction modifier sulfurized isobutylene, dodecenylsuccinic acid and phosphite ester. The nano borate engine oil is good in dynamic property, capable of saving energy, environmentally friendly, low in friction coefficient, small in ash content and long in service life.

Description

technical field [0001] The invention belongs to a nano borate engine oil and belongs to the technical field of engine oil formula. Background technique [0002] At present, domestic and foreign engine oils are facing environmental and energy challenges, and urgently need to transform and upgrade to energy saving and emission reduction. The existing engine oils mainly have the following shortcomings: 1. The existing engine oil formula design is unreasonable, and long-term use will reduce the life of the exhaust gas purification device. , a large amount of harmful gas emissions, leading to catalyst poisoning failure and exhaust pollution exceeding the standard; 2. High friction coefficient. In order to reduce the friction coefficient, ZDDP containing phosphorus and zinc is usually added to the engine oil, and the use of ZDDP containing phosphorus and zinc is subject to regulations. Restrictions; 3. The ash content of engine oil is large, and the metal ash content is extremely ...

[0002] At present, domestic and foreign engine oils are facing environmental and energy challenges, and urgently need to transform and upgrade to energy saving and emission reduction. The existing engine oils mainly have the following shortcomings: 1. The existing The formula design of the engine oil is unreasonable, long-term use will reduce the life of the exhaust gas purification device, and the amount of harmful gas emissions will be large, resulting in catalyst poisoning and exhaust gas pollution exceeding the standard; 2. The friction coefficient is high. In order to reduce the friction coefficient, phosphorus and Zinc ZDDP, and the use of ZDDP containing phosphorus and zinc is restricted by regulations; 3. The ash content of engine oil is large, and the metal ash content is extremely harmful to the normal operation of the engine; 4. The content of low-carbon chlorinated paraffin in engine oil is high, and low-carbon chlorination Paraffin wax is easy to cause cancer and damage the ozone layer; 5. If the existing engine oil has better engine oil power, the economy and safety are low, and it has high toxicity, large ash content, and strong pollution; 2. The existing more environmentally friendly engine oil , the power of the engine oil is poor, and the resistance is high, and the service life is low.
