preparation example Construction

[0044] Correspondingly, the present invention also provides a preparation method of lubricating oil for chains that meets the hygienic requirements of "lubricant that occasionally comes into contact with food", comprising: providing 45-66 wt% of synthetic esters, 30-50 wt% of synthetic hydrocarbons and 1 ~9wt% additives; the synthetic ester meets the hygienic requirements of "lubricants that come into contact with food accidentally"; the synthetic hydrocarbon meets the hygienic requirements of "lubricants that come into contact with food accidentally"; Lubricants" hygienic requirements.

[0045] Specifically, the step of providing the synthetic ester, the synthetic hydrocarbon, and the additive includes: putting the synthetic ester, the synthetic hydrocarbon, and the additive into a reactor; putting the synthetic ester, the synthetic hydrocarbon And in the step of mixing the additives and constant temperature stirring to obtain the chain lubricating oil, the process temperatur...

Embodiment 1

[0049] Mix 45wt% of trimellitate, 38wt% of PAO40, 12wt% of butene homopolymer and 5wt% of additives, and stir at a constant temperature of 70°C to 80°C for 30 minutes to obtain a lubricating oil for chains. Among them, trimellitate and additives meet the health requirements of the National Sanitation Foundation HX-1; PAO40 and butene homopolymer meet the health requirements of the National Sanitation Foundation H-1.

Embodiment 2

[0051] Mix 50wt% of trimellitate, 30wt% of PAO6, 15wt% of butene homopolymer and 5wt% of additives, and stir at a constant temperature of 70°C to 80°C for 30 minutes to obtain a lubricating oil for chains. Among them, trimellitate and additives meet the health requirements of the National Sanitation Foundation HX-1; PAO6 and butene homopolymer meet the health requirements of the National Sanitation Foundation H-1.

Abstract

The invention provides lubricating oil which is used for a chain and meets the sanitary requirement of a 'lubricating agent capable of being contacted with food by accident' and a preparation method thereof. The lubricating oil used for the chain comprises 45-66wt% of synthetic ester, 30-50wt% of synthetic hydrocarbon and 1-9wt% of an additive, wherein the synthetic ester, the synthetic hydrocarbon and the additives respectively meet the sanitary requirement of the 'lubricating agent capable of being contacted with food by accident'. According to the technical scheme of the invention, the synthetic ester and synthetic hydrocarbon are adopted as base oil, and ratio of the synthetic ester to the synthetic hydrocarbon is adjusted, so that the obtained lubricating oil used for the chain not only has the characteristics of high temperature resistance, low volatilization rate and high dissolubility of deposited carbon but also can effectively realize cost control while meeting the sanitary requirement of the 'lubricating agent capable of being contacted with food by accident'.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil for chains and a preparation method thereof that meet the hygienic requirements of "lubricants that occasionally come into contact with food". Background technique [0002] In the production of food, cosmetics, pharmaceuticals, tobacco and animal feed, lubricants are used in mechanical equipment such as gears, bearings, hydraulic devices, pneumatic devices, compressors, slides and chains. Although it is the most basic requirement to avoid lubricant contamination as much as possible, in many cases, the product and lubricant cannot be completely isolated, and the product and lubricant will come into contact accidentally. In this case, it is necessary to use a lubricant with higher safety, so that the safety of the product can be guaranteed in the event of cross-contamination. [0003] Chain is an important part of mechanical transmission and has a wide ra...
