Method for preparing water-base chain lubricant

Abstract

The invention relates to a process for preparing lubricating agent which is used on high-speed conveyer belt production line such as PET bottles, glass bottles, tins and the like, which belongs to the preparation filed of chemical lubricating agent. The components and quality percentages of lubricating agent which are prepared by the process for preparation are that triethanolamine oleate 3-8%, triethanolamine 4-9%, LF-131 2-5%, isothiazolone 1-3%, polymaleic acid 0.5-2%, glucuronidase 4-9%, EDTA-2Na 4-10%, benzotriazole 0.5-2%, sodium dimethyl benzene sulfonate 0.5-2%, H2O 65-75%, the water-base chain lubricating agent has high lubricating property and excellent solubility, which has multinomial excellent properties such as hard water resisting, sterilization, low foaming, non corrosiveness, crack resistance, coagulability resistance and the like, when the lubricating agent is used in lubricating systems, the lubricating system can effectively reduce bottle inversing rate, improve workplace environment and prolong service span of chain mats.

Description

【Technical field】 [0001] The invention relates to a method for preparing a lubricant used in high-speed conveyor belt production lines such as PET bottles, glass bottles, and cans, and belongs to the field of chemical lubricant preparation. 【Background technique】 [0002] Lubricants for the lubrication system of the filling line have experienced more than 40 years of development. In the original semi-automatic filling system, the bottle conveying speed of the production line was only a few hundred bottles to one thousand bottles per hour. The bottle conveying system did not have a special lubricant, and the bottle and the chain were in a state of dry friction, so the wear of the chain was serious. Later, people noticed this problem and installed a soap soaking tank for the bottle conveying system to lubricate the chain with soap, which solved the problem of chain wear to a certain extent. But this type of lubricant has the following disadvantages: (1) poor solubility, easy ...

AI Technical Summary

Problems solved by technology

However, this type of lubricant has the following disadvantages: (1) poor solubility, easy hydrolysis, and poor resistance to hard water

The dilution factor is small (generally no more than 50 times), and the solid content is high, which can easily cause blockage of the delivery pipe and nozzle

(2) Poor antibacterial property, no bactericidal (yeast) ability, no antirust ability, low lubricating effect, high unit consumption

(3) If the dipping method is adopted on the high-speed filling line, due to the high speed, it is easy to produce a large amount of foam to pollute the packaging trademark, which directly affects the appearance quality of the product, and at the same time will cause a large amount of foam on the production line and on the ground, which cannot reach Cleaner Production Requirements

Otherwise, the accumulated scale from long-term use will block the sprayer, and even block the pipeline, causing the centralized lubrication system to be paralyzed
