Problems solved by technology

Adding suitable solid powder to the lubricating oil is a good way to improve the waterproof performance. For example, the invention application CN01115610.4 provides a kind of lubricating grease for gas pipeline valves. Its composition adds 0-30% mica powder, Calcium carbonate or calcium phosphate is preferably added with mica powder. This kind of grease is characterized by high dropping point, good flame retardancy and good insulation, but its production cost is high, so it is not suitable for special grease for injection molding machine joints; invention Application CN200610113499 discloses a water-resistant lubricating grease, adding molybdenum disulfide, tungsten disulfide, flake graphite, colloidal stone ink, micropowder graphite, mica powder, talcum powder, calcium fluoride, calcium carbonate, barium carbonate, thioantimony acid One or more of antimony, copper powder, aluminum powder, lead powder, and molybdenum dibutyldithiocarbamate. This lubricating oil is mainly used for underwater working conditions, so it is not suitable for injection molding machine joints Grease; Invention application CN200810057199 provides an open gear grease composition, which adds graphite, molybdenum disulfide, polytetrafluoroethylene, tungsten disulfide, melamine, calcium carbonate, calcium phosphate, calcium sulfate, barium sulfate, carbonic acid Barium or mica powder, this kind of grease is relatively viscous due to the addition of polyisobutylene, it is not suitable for pumping, and cannot be used for centralized lubrication, so it is not suitable for joint grease of injection molding machines

Abstract

The invention relates to a lubricating oil for joints of an injection molding machine. The lubricating oil is prepared from the following raw materials by weight: 85 to 95 parts of mineral-based oil, 15 to 25 parts of polyoxyethylene nonyl phenyl ether, 3 to 5 parts of hexachlorocyclopentadiene, 3 to 5 parts of dithioglycol, 5 to 10 parts of propolis extract, 5 to 10 parts of alga extract, 10 to 15 parts of graphene, 5 to 10 parts of modified zircon powder, 1 to 3 parts of methyl carbamate and 2 to 4 parts of benzimidazole. The lubricating oil provided by the invention has good abrasion resistance, resistance to tarnishing, heat stability, anti-foaming performance, good sealing adaptability and high cleanliness and can meet requirements of the hydraulic system of the injection molding machine on lubricating oil. The lubricating oil has high adhesion and is not prone to rapid loss. A preparation method for the lubricating oil is simple, convenient for industrial production and low in cost.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a lubricating oil for joints of an injection molding machine with good anti-rust, anti-oxidation, extreme pressure and anti-wear properties. Background technique [0002] Injection molding machine, referred to as injection machine or injection molding machine, is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding machines are widely used in national defense, electromechanical, automobiles, transportation, building materials, packaging, agriculture, culture, education, health and people's daily life. In today's rapid development of the plastics industry, injection molding machines play an important role in both quantity and variety.
