Problems solved by technology

[0005] However, the working condition of the plate continuous press is harsh, there are a lot of sawdust and formaldehyde, and it cannot be stopped easily, which will cause huge economic losses. The workload of cleaning coking is huge, and the equipment is huge. The press is 25-50 meters long, 3 meters wide, and high. About 3 meters, the system is complex, each component must operate independently, and requires high synchronization, no sliding friction between components, and high pressure load, up to 300MPa, many lubrication points: steel belt, chain blanket, chain , driving roller, driven roller, etc.

preparation example Construction

[0051] The present invention also provides a method for preparing the above-mentioned special high-temperature lubricating oil for continuous press steel strips in the plate processing industry, including:

[0052] a) mixing the aromatic acid mixed alcohol ester with a tackifier to obtain a base oil;

[0053] b) After heating and mixing the base oil, antioxidant, extreme pressure anti-wear agent, anti-corrosion agent and equalizer obtained in the above steps, a high-temperature lubricating oil for continuous press steel strips in the plate processing industry is obtained.

[0054] In the present invention, the aromatic acid mixed alcohol ester is first mixed with the tackifier to obtain the base oil; the mixing temperature is preferably 90°C to 100°C, more preferably 96°C to 100°C; the present invention has no special limitation on the mixing method , get final product with the mixing method well-known to those skilled in the art, and the present invention is preferably agitat...

Embodiment 1

[0063] 1. Pump 73.5g of aromatic acid mixed alcohol ester A and 21g of polyisobutylene into a blending kettle, heat to 90°C, vacuumize and stir evenly to obtain base oil;

[0064] 2. Add 2.0g of extreme pressure anti-wear agent and 0.08g of anti-corrosion agent 1 into the blending kettle, heat, stir, and evacuate to -0.090MPa, after heating to 130°C, dissolve at constant temperature for 3 hours to obtain the mixing aid;

[0065] 3. Mix the base oil obtained in step 1, the mixing aid obtained in step 2, 3g of antioxidant and 0.42g of equalizer dialkyldithiocarbamate, then heat to 120°C, and then vacuumize and keep the temperature Stir for 1h to obtain a mixture;

[0066] 4. Cool down the mixture obtained in the above steps and filter to obtain a special high-temperature lubricating oil for continuous press steel strips in the plate processing industry.

Embodiment 2

[0068] 1. Pump 64.47g of aromatic acid mixed alcohol ester B and 30g of polyisobutylene into the blending kettle, heat to 100°C, vacuumize and stir evenly to obtain base oil;

[0069] 2. Add 2.0g of extreme pressure anti-wear agent, 0.08g of anti-corrosion agent 1 and 0.03g of anti-corrosion agent 2 into the preparation kettle, heat, stir, and evacuate to -0.095MPa, after heating to 140°C, dissolve at constant temperature for 4 hours to obtain mixing aids;

[0070] 3. Mix the base oil obtained in step 1, the mixing aid obtained in step 2, 3g of antioxidant and 0.42g of equalizer, then heat to 140°C, and then vacuumize and stir at constant temperature for 2 hours to obtain a mixture;

[0071] 4. Cool down the mixture obtained in the above steps and filter to obtain a special high-temperature lubricating oil for continuous press steel strips in the plate processing industry.

Abstract

The invention provides special high-temperature lubricating oil for a steel belt of a continuous press for the plate processing industry. The special high-temperature lubricating oil comprises the following components in percentage by mass: 45-94wt% of aromatic acid mixed alcohol ester, 5-54wt% of a thickening agent, 0.1-5wt% of an antioxidant, 0.1-5wt% of an extreme pressure antiwear additive, 0.005-0.5wt% of a corrosion inhibitor and 0.01-0.5wt% of a balancing agent, wherein the aromatic acid mixed alcohol ester is an ester compound of a mixed alcohol composed of C8-C16 fatty alcohols and / or C8-C16 branched-chain alcohols, and the sum of the mass percentage of all the components is 100wt%. The special high-temperature lubricating oil for the steel belt of the continuous press for the plate processing industry has the characteristics of excellent low temperature resistance performance, high corrosion resistance and good wear resistance and can meet the requirement for a complex condition of the continuous press.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a special high-temperature lubricating oil for continuous press steel strips in the plate processing industry and a preparation method thereof. Background technique [0002] The board processing industry includes: solid wood floor processing industry, bamboo floor processing industry, particle board processing industry and medium and high density fiberboard processing industry. The latter two are collectively referred to as the wood-based panel processing industry, which requires high equipment and technology.
