Embodiment 1

[0044] The present invention is used for preparing the system of high temperature additive for aluminum cold rolling such as figure 1 , including a reaction kettle 1, a feed pipe 2, the feed pipe 2 is connected with a drying room 3, and the drying room is heated with hot water at a temperature of 80°C. The feed pipe 2 is also connected with a base oil feed port 4 and an antioxidant feed port 5 .

[0045] The reaction kettle 1 has a jacket, and the inlet 6 and the outlet of the boiler return water are arranged on the jacket, and the temperature of the boiler return water is 45°C. There is a stirring device in the reaction kettle 1. According to the total mass of reactants, 1000kg is stirred for about 30-50 minutes.

[0046]The side of the reaction kettle away from the raw material inlet is connected to a vacuum pump 9 and a buffer tank 10 through a pipeline, and the vacuum pump 9 is used for vacuum suction. The bottom of the reaction kettle 1 is provided with a discharge filt...

Abstract

The invention provides a high-temperature additive for rolling oil used in cold rolling of aluminum strips, which belongs to the field of lubricant compositions. The high-temperature additive is composed of a low-molecular-weight thickening agent, an anti-oxidant and base oil, wherein the anti-oxidant is one or more selected from the group consisting of a hindered phenol anti-oxidant, an aromatic amine anti-oxidant, an thiodipropionic diester anti-oxidant and a phosphite anti-oxidant, and the mass percentage contents of the low-molecular-weight thickening agent, the anti-oxidant and base oil are 4 to 80%, 0.01 to 3% and 17 to 95%, respectively. According to the invention, through reasonable adjustment of the ratio of low-molecular-weight thickening agent to anti-oxidant to base oil, integral high temperature performance of the rolling oil can be improved in cold rolling of aluminum strips without changing conventional base oil, composite additives and process; and the high-temperature additive has guaranteed high lubricity at a high temperature, is easy to clean and reduces occurrence probability of annealing oil marks.

Description

technical field [0001] The invention belongs to the field of lubricating compositions, and in particular relates to a lubricating agent composition containing aliphatic additives, a preparation method and application thereof. Background technique [0002] Cold rolling of aluminum sheet and strip is usually carried out in a 4-roll or 2-roll mill, and the raw material is hot-rolled billet or cast-rolled billet. Aluminum rolling oil is composed of base oil and compound additives. The base oil for cold rolling of aluminum plate and strip is mostly low-viscosity, light mineral oil. Moreover, the viscosity of the base oil for cold rolling of aluminum plate is slightly higher than that of aluminum foil, and the viscosity of base oil for high-speed rolling is slightly higher than that of aluminum foil. lower than low speed rolling. Products sometimes require finished annealing or intermediate annealing, which requires higher surface quality, including plate shape and surface bright...
