Problems solved by technology

At present, high-temperature chain lubricating oils at home and abroad only add corresponding anti-oxidation and anti-wear additives to ensure this performance of high-temperature chain lubricating oils. The high-temperature chain lubricating oil composition of 200910236609.8 uses ordinary anti-wear agents, and does not mention the reduction of the friction coefficient that plays a key role in the operation of the chain

preparation example Construction

[0040] The present application also provides a preparation method of the chain oil compounding agent, which is characterized in that it includes the step of mixing the components of the compounding agent.

[0041] Preferably, the method comprises the steps of:

[0042] (1) Add softening oil to the container;

[0043] (2) add amine antioxidant, phenolic antioxidant, stirring and dissolving;

[0044] (3) Add anti-wear agent, friction modifier and ashless anti-rust agent, and stir evenly to obtain the composite agent.

[0045] More preferably, the method comprises the steps of:

[0046] (1) Pour softened oil into a stainless steel blending kettle and heat to 85-95°C;

[0047] (2) Add amine antioxidants and phenolic antioxidants, stir and dissolve at a constant temperature of 85-95°C;

[0048] (3) Cool down to 40-60°C, add antiwear agent, friction modifier, ashless antirust agent, stir evenly, and filter to obtain the finished compounding agent.

Embodiment 1

[0051] Pour 50 parts of softened oil dipentaerythritol ester (HATCOL of the United States, brand HATCOL3165, the same below) into a clean stainless steel blending kettle, heat to 90°C, add amine antioxidant p-, p-octyl diphenylamine (BASF, Germany, brand IRGANOXL01, the same below) 15 parts, add 11 parts of phenolic antioxidant containing thioether group phenol (Germany BASF company, IRGANOXL115, the same below), stir evenly at 90°C for 40 minutes; cool down to 55°C, add polyester type 8 parts of friction modifier (British Croda Company, brand Perfad3000, the same below), add 11 parts of ashless antiwear agent antimony dialkyldithiocarbamate (U.S. Tiarco company, brand OctopolPTB, the same below), ashless Antirust agent ammonium phosphate compound (Vanderbilt Company of the United States, brand name Vanlube9123, the same below) 5 parts, stirred evenly for 30 minutes, and filtered to obtain the finished compound agent I.

Embodiment 2

[0053] Pour 50 parts of dipentaerythritol ester of softened oil into a clean stainless steel blending kettle, heat to 90°C, add 11 parts of amine antioxidant p-, p-octyl diphenylamine, and add 15 parts of phenolic antioxidant containing thioether group phenol , Stir evenly at 90°C for 40 minutes; cool down to 55°C, add 4 parts of polyester friction modifier, add 15 parts of ashless antiwear agent antimony dialkyldithiocarbamate, ashless antirust agent phosphoric acid 5 parts of ammonium compound, stirred evenly for 30 minutes, and filtered to obtain the finished compound agent II.

Abstract

The invention relates to a chain lubricating oil composite agent and a preparation method thereof. The chain lubricating oil composite agent is characterized in that it comprises the following components by mass percentage: 40-60 mass% of softening oil; 10-20 mass% of an amine antioxidant; 8-20 mass% of a phenolic antioxidant; 8-20 mass% of an antiwear agent; 1-10 mass% of a friction improver; and 1-10 mass% of an ashless antirust agent. The high temperature chain lubricating oil prepared from the composite agent provided by the invention has superstrong oxidation resistance, wear resistance and corrosion resistance, so that the high temperature chain can acquire lower friction coefficient in work, safer and more reliable machine operation is ensured, the comprehensive performance is more excellent, and the antirust capability of the chain metal is further enhanced.

Description

technical field [0001] The present application relates to a chain lubricating oil compounding agent, more precisely, a chain lubricating oil compounding agent with super high-temperature anti-oxidation stability, friction reduction and energy saving. Background technique [0002] A chain is a metal link or ring used for mechanical transmission or traction. With the rapid development of industry, machinery and equipment are changing with each passing day, and the operating temperature of working conditions is getting higher and higher. Because of the special high temperature resistance performance of the high temperature chain, it is widely used in more occasions. Therefore, the development trend of the new generation of high-temperature chain lubricating oil is to have more excellent oxidation stability and thermal stability to ensure or extend the oil change interval of the oil. At the same time, it also needs to have excellent anti-wear properties, friction reduction and ...
