Abstract
The invention discloses lubricating oil and a lipstick tube middle beam core using the same; the lubricating oil comprises the following raw materials by volume: 35-70% of polyisobutylene, 0-60% of medium-viscosity synthetic hydrocarbon base oil, and 5-30% of low-viscosity synthetic hydrocarbon base oil. The medium-viscosity synthetic hydrocarbon base oil has a kinematic viscosity of 20-40 cst below 100 DEG C, has a kinematic viscosity of 200-240 cst below 40 DEG C, has a pour point of less than -40 DEG C, and has a viscosity index of more than 130; the low-viscosity synthetic hydrocarbon base oil has a kinematic viscosity of 1-10 cst below 100 DEG C, has a kinematic viscosity of 20-40 cst below 40 DEG C, has a pour point of less than -40 DEG C, and has a viscosity index of more than 130. When the lubricating oil of the invention is applied to a lipstick tube or a lipstick tube middle beam core, the torsion of the lipstick tube middle beam core is up to 0.5-4.5 in.oz, and is basically within a range of 2.0-3.0 in.oz, which ensures that the product quality meets related industrial standards.
Description
Technical field
The present invention relates to a kind of lubricating oil, relate in particular to a kind of lipstick tube with lubricating oil and use Shu Xin in its lipstick tube.
Background technology
The major parts of lipstick tube is inner middle Shu Xin; In Shu Xin by the coaxial successively pearl that wears, fork, spiral and middle Shu Zucheng from inside to outside; Wherein spiral and middle bundle are fixedly sleeved; The spiral inner peripheral surface is provided with the volution notch, and fork is provided with the long strip shape slide opening that is provided with vertically, and the pearl periphery is provided with and passes the long strip shape slide opening and stretch into the convexity in the volution notch.In the relative fork rotation process of spiral, pearl is along the slide opening to-and-fro movement, in release of lipstick cream or withdrawal lipstick tube.Have certain torsion when rotating, often need on fork and pearl, smear one deck lubricating oil in order to make.But existing lubricant often can't reach corresponding viscosity standard.
Summary of the invention
The invention provides a kind of lubricating oil, this lubricated spreading upon between lipstick tube, the fork, torsion can satisfy corresponding industry standard requirement.

Kinematic viscosity under 100 ℃ of the described LV synthin base oils is 1～10cst, and the kinematic viscosity under 40 ℃ is 20～40cst, and pour point is lower than-40 ℃, and viscosity index is greater than 130.
The optional synthin base oil SinoSyn25 that provides with the general chemistry of Shanghai Road of medium viscosity synthin base oil; They have very high viscosity index (157); Lower pour point (45 ℃), good low temperature flowability and shear stability have good consistency with MO.Kinematic viscosity under 100 ℃ of this base oils is 25～28cst, and the kinematic viscosity under 40 ℃ is 200～240.
LV synthin base oil can be selected from the synthin base oil PA06 that the general chemistry of Shanghai Road provides, and has high viscosity index (HVI) (135), low pour point (68 ℃), and volatility is low, has good thermooxidizing, hydrolysis stability.Kinematic viscosity under 100 ℃ of this base oils is 4～6cst, and the kinematic viscosity under 40 ℃ is 25～35cst.
More elect as, in volume percent, raw material consists of:
Polyisobutene 35～50%
Medium viscosity synthin base oil 35～50%
LV synthin base oil 5～15%.
The molecular weight of described polyisobutene is 1000～5000, more preferably 1000～2000.
During preparation, only need after above-mentioned three kinds of raw materials mix, stirring got final product in 1～2 hour under 60～100 ℃.
The present invention also provides bundle core or lipstick tube in the lipstick tube of above-mentioned lubricating oil.
Among the Shu Xin time, bundle core torsion can reach 0.5～4.5in.oz to lubricant applications of the present invention in the lipstick tube in lipstick tube or lipstick tube, and basically in 2.0～3.0in.oz scope, can guarantee that quality product meets the industry relevant criterion.
