Description
Technical Field
The invention relates to the technical field of high-temperature chain oil, in particular to a synthetic chain oil composition with excellent high-temperature adhesion and a preparation method thereof.
Background
Textile post-processing equipment such as heat-setting machines, dryers, printing machines and the like are widely used for chain transmission and are generally lubricated by oil. The chain operation temperature of the textile post-treatment equipment is generally higher, the highest temperature is more than 250 ℃, and the highest speed of the chain is more than 120 m/min. The chain used by the post-treatment equipment, particularly the heat setting machine, is as long as 100m, the drying room has more speed saving, and the chain works in the drying room for a long time. On the other hand, the chain runs in the working environment of water-rich, water-vapor-rich and polyacid-base medium. Further, the development of post-processing equipment is advancing toward higher speed, more energy saving, longer life, no or little maintenance. In sum, the textile post-treatment equipment puts a strict requirement on the performance of the high-temperature chain oil. (1) little coking. The chain oil is attached to the chain and the guide rail after coking, so that the phenomena of retardation, dragging and the like occur when the chain runs, the friction, impact load and motor current are increased, the chain abrasion, fatigue and energy waste are aggravated, and the chain is seriously and even causes tooth jumping, chain dragging, fracture or motor burnout. Coking is a product of high-temperature oxidation of chain oil, and the presence of water, steam, acid and alkali substances and floccules can aggravate oxidation and increase the coking amount. Coking is inevitable, good chain oil has stable chemical structure, less oil coke is generated and can be taken away, and the maintenance and decoking period of the chain oil can be prolonged. (2) excellent high-temperature adhesion. High temperature adhesion refers to the oil film retention capability of the chain oil at high temperatures. The high-temperature adhesion is excellent, the oil film holding capacity is strong, the high-temperature lubrication of the chain oil is good, the coking quantity can be reduced, and the energy consumption and the abrasion can be reduced. The high-temperature adhesion is closely related to the viscosity index, the viscosity of the chain oil decreases less with the increase of the temperature, and the chain oil can be better adhered to the surface of a friction point at high temperature. And (3) the permeability is strong. There is a little clearance between the inner and outer chain plates of the chain and between the roller and the inner chain plate, and the chain oil permeates into the friction surfaces between the sleeve and the pin shaft and between the roller and the sleeve through the clearance respectively. The chain oil with poor permeability is difficult to enter a friction point, so that the chain abrasion is aggravated and even the occlusion is generated, and the service life of the chain is shortened. And (4) the low-temperature performance is good. In winter, the equipment is stopped for a long time, and when the equipment is restarted, the viscosity of chain oil is too high or the chain oil is solidified, so that the equipment is difficult to start, the preheating time is prolonged, and even a frequency converter or a motor can be burnt.
The technical development of the high-temperature chain oil goes through three stages of mineral oil type high-temperature chain oil, polyether type high-temperature chain oil and synthetic ester type high-temperature chain oil, and the development process is resisted to a high level. At the temperature of 140-160 ℃, the mineral oil type chain oil is quickly oxidized to form carbon deposit with high volatility. The polyether type high-temperature chain oil has the highest use temperature of about 220 ℃, high viscosity index and less residue, but has poor compatibility with paint, fast high-temperature decomposition and influence on the environment of a factory. The synthetic ester type high-temperature chain oil comprises meta-phenyl ester type high-temperature chain oil and polyol ester type high-temperature chain oil. The highest use temperature of the meta-phenyl ester type high-temperature chain oil is generally 250 ℃, the evaporation loss is small, but the high temperature is easy to coke, and the cleaning work of workers on the surface of the chain is increased. Polyol ester type high-temperature chain oil, particularly pentaerythritol ester, has the advantages of high oxidation resistance, less coking and high viscosity index, but has low viscosity, and can not form an oil film with enough thickness and lubrication at high temperature, so that a part of a degreasing agent is required to be added to improve the viscosity. The common adhesives used in polyol ester type high temperature chain oils currently on the market are Polyisobutylene (PIB) and Polymethacrylate (PMA). The properties of the traditional sticking agent, such as high-temperature oxidation stability, shear stability, low-temperature performance and the like, have great influence on the performance of the polyol ester type high-temperature chain oil, so that the poor high-temperature adhesion and the increased coking amount of the polyol ester type high-temperature chain oil are caused.
