[0027] Mix the required amount of base oil, oily agent, tackifier, and anti-corrosion agent, heat to 60°C, stir at constant temperature for 60 minutes, and pack in cans after passing the inspection. Wherein each component and its parts by weight are shown in Table 1, and the product properties are shown in Table 2.

[0028] In Table 1, DOP is diisooctyl phthalate, DOA is dibutyl phthalate, PB2400 is polyisobutylene with molecular weight of about 2400, JINEX1300 is polyisobutylene with molecular weight of 1300, and VL700 is polyisobutylene with molecular weight of 100000. ethylene propylene rubber, T706 is benzotriazole, T561 is thiadiazole derivatives, HVI I75, HVI I150 are solvent refined mineral oil, HVI II6 is hydrogenated refined mineral oil.

[0029] HVI I75 has a kinematic viscosity of 15mm at 40°C 2 / s, the kinematic viscosity of HVI I150 at 40°C is 30mm 2 / s, HVI II6 has a kinematic viscosity of 30mm at 40°C 2 / s.

[0030] In Table 2, PB is the maximum non-seizing ...

Abstract

The invention relates to a copper tube drawing internal film oil composition and its use, and mainly solves a problem that cleaning must be carried out before annealing due to low annealing cleanness of oil products in the prior art. The composition comprises, by weight, 5-35 parts of an oiliness agent, 30-70 parts of a tackifier, 0.01-0.5 parts of an anticorrosive agent and 5-35 parts of base oil. The above technical scheme well solves the problem, and can be used for the industrial production of the copper tube drawing internal film oil composition.

Description

technical field [0001] The invention relates to a copper pipe drawing inner film oil composition and its application. Background technique [0002] With the development of my country's electric power, electronics, automobile and household appliances industries, the demand for copper tubes, especially copper tubes for heat exchangers, is increasing. Copper tube manufacturers are gradually changing the straight-chain drawing process into coiled tubes. Drawing process. This is due to the latter's high production efficiency, high yield, small drawing force and the ability to produce coiled copper tubes with a long length that can adapt to the requirements of the above-mentioned industrial automatic production lines. [0003] As we all know, copper tube drawing belongs to the category of plastic processing, which is different from steel processing. For example, it does not require high extreme pressure performance but has high requirements for anti-wear and friction reduction, hi...
