Problems solved by technology

The lubricating oil used for the sealing ring of the existing tire internal mixer not only consumes oil, but also cannot meet the requirements of environmental protection. In this way, the cost of the produced tires not only increases, but also cannot meet the EU REACH environmental protection regulations, which has caused greater pressure on the tire industry. The loss caused the tire industry to suffer a greater blow

Abstract

The invention relates to special environment-friendly lubricating oil for seal rings of internal mixers for tires. The technical scheme includes that the special environment-friendly lubricating oil is prepared from, by weight, 85-92 parts of environment-friendly naphthenic oil, 6-12 parts of dioctyl terephthalate, 1-7 parts of molybdenum dialkyl-dithiophosphate, 0.05-0.15 part of emulsified silicone oil, 0.8-2.8 parts of overbased sulfurized calcium alkyl phenolate and 1.0-1.9 parts of zinc dialkyl dithiophosphate. The special environment-friendly lubricating oil has advantages that 1, the special environment-friendly lubricating oil for the seal rings of the internal mixers for the tires is high in economic value, conventional naphthenic oil cost is greatly reduced, and a convention that naphthenic oil is only used as rubber filling oil rather than lubricating oil previously is broken; 2, due to addition of additives, the lubricating oil can be used as oil for the seal rings of the internal mixers, has effects of abrasion resistance and abrasion reduction and is capable of protecting the seal rings, prolonging service lives of the seal rings and keeping high durability of gaps of the seal rings to realize a tightly closed state, and compared with conventional naphthenic oil, the special environment-friendly lubricating oil has advantages of oil saving and energy saving; an aniline point can be adjusted at any time according to rubber tire ratio requirements, so that a naphthenic oil utilization range is greatly expanded.

Description

technical field [0001] The invention relates to a lubricating oil for the sealing ring of a tire internal mixer, in particular to a special environment-friendly lubricating oil for the sealing ring of a tire internal mixer. Background technique [0002] The internal mixer is an indispensable equipment in the modern rubber industry, mainly used for mastication and mixing of rubber. The rotor sealing device is generally in two forms of mechanical seal and hydraulic seal, adopts the principle of contact end face seal, and sets a pair of relatively rotating sealing rings—a plane friction pair composed of a moving ring and a static ring. The sealing ring is made of metal material. In order to improve the wear resistance of the sealing ring, hard wear-resistant alloy is often surfacing on the friction surface. During the working process, high-pressure lubricating oil will be injected into the friction surface of the two rings through the oil injection hole. To increase the wear r...
