Embodiment 1

[0018] With reference to Fig. 2, be the graphite of 5 parts, the calcium sulfonate of 5 parts by weight (the same below), the base oil of 10 parts of 500SN, the base oil of 40 parts of 150SN is added in the emulsification kettle and carries out dispersion emulsification After 1 hour, the temperature is automatically raised to 60°C under the action of the high-speed shear emulsifier, and the product is transported to the dehydration kettle for heating, vacuumed and dehydrated under negative pressure. The heating temperature is controlled at about 60°C, and the negative pressure is controlled at 0.08Mpa. After 2 hours, transport the product back to the emulsification kettle, add 10 parts of polymethacrylate and ethylene-propylene rubber copolymer, carry out emulsification and dispersion for 1 hour, and then transport the product back to the dehydration kettle for heat preservation and dehydration for 0.5 hours, and the heat preservation temperature is controlled At 60°C, the prod...

Embodiment 2

[0020] Be the graphite of 10 parts, the monosuccinimide of 10 parts by parts by weight (the same below), the base oil of 13 parts of 500SN, the base oil of 52 parts of 150SN adds in the emulsification kettle and carries out dispersion emulsification 2 hours, in Under the action of the high-speed shear emulsifier, the temperature is automatically raised to 70°C, and the product is transported to the dehydration kettle for heating, vacuumed and dehydrated under negative pressure. The heating temperature is controlled at about 67°C, the negative pressure is controlled at 0.08Pa, and the time is 2.5 hours. Transfer the product back to the emulsification tank, add 15 parts of polymethacrylate, emulsify and disperse for 2 hours, and then transfer the product back to the dehydration tank for heat preservation and dehydration for 1 hour. The temperature of the heat preservation is controlled at about 67°C, and the product is filtered out Finished products, the filter diameter is contro...

Embodiment 3

[0022] Be the graphite of 15 parts, the bis-succinimide of 15 parts by parts by weight (the same below), the base oil of 16 parts of 500SN, the base oil of 64 parts of 150SN adds in the emulsification kettle and carries out dispersion emulsification 3 hours, in Under the action of the emulsifier, the temperature is automatically raised to 80°C, and the product is transported to the dehydration kettle for heating, vacuumed and dehydrated, the heating temperature is controlled at 75°C, the negative pressure is controlled at 0.09Mpa, and the time is 3 hours, and the product is transported again Add 20 parts of dispersed polymethacrylate to the emulsification kettle, emulsify and disperse for 3 hours, then transport the product back to the dehydration kettle for heat preservation and dehydration, and keep the heat preservation temperature at 75°C for 1.5 hours, filter the product out of the finished product, and filter The filter diameter is controlled at no more than 10 μm.

Abstract

The prsent invention relates to a method for preparing compound internal combustion engine oil additive. Said method includes the following steps: placing proper quantity of graphite, dispersing agent with the function of dispersing graphite, base oil of 500SN and the rest base oil of 150SN into an emulsifier still to disperse and emulsify, heating to 60-80 deg.C by the action of emulsifier, heating in dewatering still, vacuum-pumping, negative pressure dehydrating, heating, controlling negative pressure at 0.08-0.09 Mpa, and time in 2-3 hr, then transferring the above-mentioned material into emulsifier still and adding stabilizing agent, emulsifying and dispersing for 1-3 hr, then transferring it back into dewatering still to dehydrating and preserving heat, filtering so as to obtain the invented product.

Description

technical field [0001] The invention relates to a preparation method of lubricating oil additives, in particular to a preparation method of composite internal combustion engine oil additives. Background technique [0002] Referring to Figure 1, at present, a production method for producing energy-saving and anti-friction additives is to acidify, wash and purify the graphite filter cake (with a water content of 70%), and then knead, disperse, and remove water with the dispersant KL83-21 Finished product after the process. The method has complex technological process, long time (the whole technological process is about more than 100 hours), high labor intensity and expensive product cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for manufacturing a composite internal combustion engine oil additive in order to overcome the above-mentioned deficiencies in the prior art. The preparation method has sim...
