Embodiment 1～5

[0041] Put the biodegradable base oil into the blending tank, stir, heat up to 50°C and maintain at this temperature; add extreme pressure anti-wear agent, stir evenly; then add surfactant, stir evenly; finally add rust inhibitor and thickener and antifoaming agent, stirring and stopping heating, gradually cooling down to room temperature, stopping stirring to obtain the composition. The type and amount of each component in the composition are specifically shown in Table 1.

[0042] In Table 1, AEO is fatty alcohol polyoxyethylene ether, EL is castor oil polyoxyethylene ether, MC944V is polyisobutylene derivative, and 4010 is the trade name of high-viscosity polyester.

Embodiment 1

[0048] The composition was prepared according to the document CN102031186A [Example 1]. Its composition is:

[0049] 35 parts of castor oil; 3.9 parts of polyether with a molecular weight of 50,000; 3.5 parts of vulcanized lard; 10 parts of chlorinated paraffin; 5 parts of trialkyl phosphate; 2 parts; 12 parts of castor oil polyoxyethylene ether; 10 parts of dodecenyl succinate; 2 parts of sorbitan oleate; 12 parts of polyether with a molecular weight of 20,000; 0.1 part of methyl silicone oil.

Abstract

The invention relates to a steel tube diameter expanding oil composition and uses thereof, and mainly solves the problems that chlorinated paraffin extreme-pressure anti-wear reagents and alkylphenol polyoxyethylene ether surfactants used in the prior art have effects on the human body and environment, and after use, the cycle of emulsification wastewater processing by a chemical sedimentation method is long; the steel tube diameter expanding oil composition includes the following components: by weight, a) 10-20 parts of an extreme-pressure anti-wear agent; b) 10-20 parts of a surfactant; c) 5-10 parts of a rust inhibitor; d) 10-15 parts of a thickener; e) 0.05-0.1 part of a defoaming agent; and f) 40-80 parts of biodegradable base oil; and the technical scheme of no containing of chlorinated paraffin in the steel tube diameter expanding oil composition well solves the problems, and can be used in industrial production of the steel tube diameter expanding oil composition.

Description

technical field [0001] The invention relates to a steel pipe diameter expanding oil composition and its application. Background technique [0002] Steel pipe expansion oil is mainly used for lubricating the working part of the expansion head in the production of large-diameter steel pipes, such as the large-diameter longitudinal submerged arc welded pipe dedicated to the main line of the national key project of the West-East Gas Transmission Project, which is used for strong diameter expansion, shaping and During the process of eliminating internal stress, steel pipe expansion oil as a supporting lubricating material for this special process can keep the two working surfaces of the sliding and guiding friction pairs of the pipe wall and the expansion head lubricated. The process requires steel pipe expansion oil to be used The oil film formed in the process can prevent all friction surfaces from being damaged under high pressure. At the same time, it is also required that th...
