Problems solved by technology

[0002] Since the invention of human machinery, friction and wear have always been a major problem for human beings. There are several schools of how to resist wear: 1. Compounds containing sulfur, phosphorus, chlorine, lead, and copper are generally It has high extreme pressure resistance and wear resistance, but most of them will generate acid, be corrosive to metal, have poor thermal stability or water resistance, and are not environmentally friendly
2 Nano-sized solid particles, good thermal stability, extreme pressure resistance and wear resistance, but the particles are prone to generate electrostatic groups in the cycle, blocking the filter screen; negative secondary damage to metals such as wear and tear
3. Borates and esters are a new type of lubricating and anti-wear agent, which is completely environmentally friendly, especially borates, which have no solid particles in the liquid and are chemically synthesized directly on the metal surface. They have good anti-wear properties, but the disadvantage is that they are anti-wear Poor water resistance, due to the thin film formed, the extreme pressure resistance is poor

Embodiment 1

[0038] S1: Pour 4% sodium di-n-butyldithiocarbamate, 4% ethylene oxide ring-opening acid, 8% brominated hydrocarbon, 44% long-chain 42 chlorinated paraffin and 20% refined base oil into the blending kettle , the temperature was 70° C., and the reaction was stirred at a rate of 800 r / min for 45 minutes to obtain a mixed liquid A.

[0039] S2: Using three glass beakers with a stirrer, thermometer and water separation and reflux device, add 3% boric acid, 9% triethanolamine and 8% xylene to the container, set the temperature to 100°C and stir the reaction, toluene and reaction water form The azeotrope is gradually evaporated, and the generated water is separated by a water separation and reflux device. After reacting for 8-9 hours, distill under reduced pressure at 88kPa for 40 minutes to remove the remaining toluene, a small amount of water and excess ethanolamine to obtain solution B.

Abstract

The invention discloses a metal anti-wear lubricant additive for hard and soft double films and preparation method of the metal anti-wear lubricant additive, and relates to the field of automobile oiland industrial chemical. The metal anti-wear lubricant additive is prepared from the following components by weight: 1%-3% of sodium dibutyl dithiocarbamate, 1%-5% of ethylene oxide cyclohexyl acid,3%-10% of bromo-hydrocarbons, 20%-55% of long chain 42 chlorinated paraffin, 8%-23% of refined base oil, 1%-9% of boracic acid, 4%-28% of triethanolamine and 4%-26% of dimethylbenzene. According to the metal anti-wear lubricant additive, the secondary damages such as corrosion, hydrolysis, instability and non-environmental-protection in anti-wear lubricant additives in the same industry are achieved, the functions of anti-extreme pressure and anti-friction of the anti-wear lubricant additive can be developed enduringly, and very good metal repairing function is achieved, and the metal anti-wear lubricant additive is a metal anti-wear lubricant additive which has practical value and capable of achieving environmental protection and emission reducing.
