Problems solved by technology

In addition, the temperature during assembly in the northern wind field will be lower than -10°C in winter, and many lubricants will solidify at this low temperature, making it difficult to paint
After the bolts are assembled, the lubricant is often lost by rainwater, which greatly reduces the long-term lubrication and anti-corrosion protection effect of the lubricant on the bolts

Embodiment 1

[0018] According to the ratio by weight, 10 parts of paraffin oil with a pour point of -12.0°C, 20 parts of naphthenic oil with a pour point of -39.0°C, 20 parts of naphthenic oil with a pour point of -16.0°C, 1 part of castor oil, 10 parts of graphite with a particle size of 800 mesh, 40 parts of molybdenum disulfide with an average particle size of 3.5 microns, 1 part of antimony trioxide, 1.5 parts of tungsten disulfide, 2 parts of sodium fluoride, 0.5 parts of cuprous chloride, 1.5 parts of oxide Put calcium into the reaction kettle, stir at 300-800 rpm for 1-2 hours, then add 5 parts of organic bentonite treated with octadecyltrimethylammonium chloride, and stir at 500-800 rpm Stir for 30-50 minutes to disperse all the materials evenly, and then obtain the wind power bolt lubricant. The product of the present invention is gray-black paste, and can still be painted with a brush at a low temperature of -15°C. After testing, the following data are obtained:

Abstract

The invention discloses a wind power bolt lubricant resistant to extreme pressure and water shower and convenient for low-temperature brushing. The wind power bolt lubricant is composed of, by weight, 8-20 parts of paraffin oil, 40-70 parts of naphthenic oil, 0.5-2 parts of castor oil, 5-35 parts of graphite, 20-40 parts of molybdenum disulfide, 0.5-6 parts of lubricating synergy additive, 0.5-2 parts of calcium oxide and 5-10 parts of organic bentonite. The wind power bolt lubricant is high in extreme pressure resistance and stable in torque coefficient; a large-size and high-strength wind power bolt is enabled to have low and stable torque coefficient through the wind power bolt lubricant, so that the large-size and high-strength wind power bolt is free of seizing and crawling in the process of assembly; the wind power bolt lubricant can be brushed conveniently even at low temperature of minus 15 DEG C, has good anti-water-shower effect and plays certain role in corrosion prevention and protection of the bolt.

Description

technical field [0001] The invention relates to a lubricant for bolt assembly, in particular to a lubricant for bolt assembly with good extreme pressure resistance, water spray resistance, convenient brushing at low temperature and stable torque coefficient. The lubricant is used for accurate assembly of large-size high-strength bolts in the field of wind power. Background technique [0002] Large-size high-strength bolts are mainly used for the connection of large components such as large buildings, bridges, power stations and wind power fields. With the continuous increase of the total installed capacity of wind power and the installed capacity of a single wind turbine in my country, more and more large-size high-strength bolts are used for wind turbine and tower assembly. The accurate and reliable assembly of large-size high-strength bolts is related to the safety of the entire fan and tower. Usually, the bolt needs to be coated with lubricant on the thread and the bear...
