Problems solved by technology

[0005] The new production process of vegetable oil lubricating oil of the present invention is based on the existing salad oil production process, adding cooling crystallization, filtering degreasing and lubricating oil blending processes, and freezing the saturated fatty acids that affect the low-temperature fluidity of vegetable oil from oil Crystallized out of the oil, by adjusting the cooling speed and final temperature of the oil, the crystallized triglycerides are easy to filter and obtain base oils with different pour points, which are separated from the oil by filtration, and are solved by pre-coating filter aids during filtration The crystallized saturated fatty acid triglyceride is difficult to filter, and the obtained base oil is blended with detergent and dispersant, anti-oxidant and anti-corrosion agent, anti-rust agent, extreme pressure anti-wear agent, anti-foaming agent, etc. to obtain finished lubricating oil

example

[0019] Example: 50°C soybean oil is placed in a crystallization tank ① with adjustable speed stirring, at a stirring speed of 20 rpm, through the cold brine in the jacket of the crystallization tank, the temperature is lowered to 30°C at a rate of 10°C per hour for 2 hours , adjust the stirring speed of the crystallization tank to 5 rpm, by adjusting the flow of cold brine, cool down at a cooling rate of 2 °C per hour for 12 hours to 6 °C, and maintain the temperature for 10 hours; pre-coat the weight of oil in the vertical blade filter ② 3% diatomite filter aid, and then filter the crystallized oil; when the resistance of the filter reaches the specified value, stop the oil inlet, use compressed air to blow back the solid fat filter cake, and enter the next filtration cycle, two Taiwan filters are used alternately, and the filtered soybean oil is used for standby.

Abstract

The present invention is one kind of biodegradable lubricant oil with excellent low temperature flowability and its production process. Refined vegetable oil after low temperature freezing and filtering is mixed with cleaning dispersant, antioxidant, antirust agent, extreme pressure antiwear agent, foam resisting agent, anticoagulant, etc to form the lubricant oil. The lubricant oil has excellent low temperature flowability and biodegradable performance, and may be used in field operation of forest, tour water area and other places with strict environment friendship requirement in cold area.

Description

Technical field: [0001] The invention relates to a biodegradable lubricating oil with good low-temperature fluidity and a process method for producing the lubricating oil. Disadvantages of poor low temperature fluidity of vegetable oil. Background technique: [0002] Traditional lubricating oil base oils are all made of petroleum products. Although petroleum products have the advantages of good chemical stability, wide sources, and cheap prices, due to the fact that petroleum-based lubricating oils will scatter to the ground through various channels during use , water bodies thus causing environmental pollution, coupled with petroleum products are non-renewable resources, resulting in people trying to find renewable resources to replace petroleum resources in recent years. Vegetable oil has the advantages of high viscosity index, high flash point, biodegradability, and renewable resources when used as lubricating oil raw materials. However, due to the large amount of polyun...
