LONG-LIFE SYNTHETIC HIGH-TEMPERATURE CHAIN OIL AND METHOD FOR PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/143586
Kind Code:
A1
Abstract:
Provided are a long-life synthetic high-temperature chain oil and method for preparation thereof; the total amount of synthetic ester base oil is 100 parts, and additives are 11.95–36.25 parts. Base oil is added to a product kettle for preheating; MDI is added to the product kettle, and upon stirring, is caused to melt completely, and is stirred for reaction; isotridecanol is slowly added to the product kettle, and warms upon being stirred, causing the materials in the kettle to react at a constant temperature of approximately 85–95°C; then water is added to the kettle and the constant-temperature stirring reaction is continued; heating up to 110–120°C is performed, and vacuum stirring and dehydration are performed; the vacuum is released and heating is stopped; high-temperature antioxidant, high-temperature anti-scorching agent, cleaning dispersant, and copper corrosion inhibitor are added to the kettle in sequence, and stirring is performed at constant temperature for 25–35 minutes; extreme pressure anti-wear additive is added to the kettle, and stirring is performed for 10–15 minutes to obtain a synthetic high-temperature chain oil. The present invention has outstanding oxidation stability, strong chain adhesion, high temperature of usage, and a long service life.
