Problems solved by technology

For the hydraulic system, the correct selection of hydraulic oil plays an important role. At present, although there are many kinds of anti-wear hydraulic oil on the market, there is no special hydraulic oil for the characteristics of the hydraulic system of injection molding machines.
[0004] For example, the invention application CN200410060691.0 discloses a green, clean, energy-saving and anti-wear hydraulic oil, which is composed of hydrorefined II mineral base oil, refined vegetable oil, synthetic hydrocarbon and compound additives, mainly used for pressure 10Mpa, and has high environmental requirements. The hydraulic system is relatively expensive; the invention application CN02114969.0 discloses a jack hydraulic oil, and its application conditions are obviously different from the injection molding machine hydraulic system; the invention application CN200710069908 provides an ester type flame retardant hydraulic oil, the main purpose of the invention To improve the high temperature resistance of hydraulic oil

Abstract

The invention discloses an antiwear hydraulic oil specially used for an injection molding machine, which is prepared by the following raw materials by weight percentage: 95-99% of mineral oil, 0.1-1.0% of detergent dispersant: high alkali synthesis calcium sulfonate, 0.1-1.0% of anti-oxidant: 2,6-di-tert-butyl-p-cresol and / or alkylated diphenylamine, 0.3-1.0% of extreme pressure antiwear additive, 0.2-1.0% of antioxidant and corrosion inhibitor, 0.1-0.9% of antirust: neutral dinonylnaphthalene sulfonic acid, 100-500ppm of defoaming agent and less than 0.1% of rubber swelling inhibitor. The invention also provides a method for preparing the hydraulic oil. The hydraulic oil has the advantages of excellent wearability, anti-rust performance, rotation oxygen bomb and thermal stability; simultaneously, the preparation method of the hydraulic oil is simple, is easy for industrial production and has low production cost.

Description

technical field [0001] The invention relates to the field of hydraulic systems, in particular to a special anti-wear hydraulic oil for injection molding machines. Background technique [0002] Antiwear hydraulic fluids are used to transmit force and motion in hydraulic systems. Its main function is to transmit the force applied by a certain point in the hydraulic system to other parts. At the same time, it also has the functions of lubrication, cooling and rust prevention. The reliability, accuracy and flexibility of hydraulic system operation depend to a large extent on hydraulic oil in addition to the design, material and performance of hydraulic components of the equipment. Anti-wear hydraulic oil (HM hydraulic oil) is developed on the basis of anti-rust and anti-oxidation hydraulic oil. At present, there are series of products such as alkaline high-zinc, alkaline low-zinc, neutral high-zinc and ash-free. They are divided into four grades of 22, 32, 46 and 68 according...
