CN104109419A - Low-temperature-resistant super-lubricating oil based ink for ballpoint pen - Google Patents

Abstract

The invention discloses low-temperature-resistant super-lubricating oil based ink for a ballpoint pen, belonging to the technical field of writing ink. The low-temperature-resistant super-lubricating oil based ink is composed of the following raw materials in percentage by mass: 50-70% of organic solvent, 5-35% of colorant, 5-35% of resin, 0.1-1% of viscosity modifier, 0.01-0.05% of thixotropic agent and 0.5-0.8% of additive, wherein the organic solvent is glycerin, dibutyl sebacate, 2-methyl-2, 4-pentadiol or dioctyl sebacate; the colorant is direct red 28#, solvent yellow 2#, solvent yellow 34#, solvent red 1# or basic green 4#; the resin is ester gum, benzene formaldehyde resin or stryenemaleic anhydride copolymer; the viscosity modifier is PVB (Polyvinyl Butyral)15 or PVB100; the thixotropic agent is hydrogenated castor oil or EBS (Ethylene Bis Stearamide); the additive is a BYK104s ink dispersant. The low-temperature-resistant super-lubricating oil based ink has excellent lubricating property so that people feel comfortable in writing and no line breaking phenomenon is caused.

Description

The low temperature resistant super lubricate oil base ink that ballpoint pen is used

Technical field

The invention belongs to writing ink technical field, be specifically related to the low temperature resistant super lubricate oil base ink that a kind of ballpoint pen is used.

Background technology

The oil base ink that known ballpoint pen is used is comprised of solvent, tinting material and resin conventionally, solvent makes water or water-soluble solvent conventionally, tinting material is used matching stain, basic dyestuff, fluorescence dye or substantive dyestuff conventionally, and resin is used epoxy resin or Synolac conventionally.Wherein: although make water or water-soluble solvent have viscosity low, write pressure little, write smoothly and feel compared with easily comfortable and can not cause tired strong point because writing for a long time, but be its deficiency because vapor pressure solvent is volatile greatly, while especially nib being exposed in air, there will be ink supply deficiency to write broken string phenomenon, and when being subject to slight vibration and impacting, ink is easily emerged from nib end, and when nib portion enters air, the stability of writing significantly declines.In addition, because manufacture process requirement is comparatively harsh, with regard to ball diameter 0.5 ㎜ of ballpoint pen and the nib of 0.7 ㎜, gap between ball and round-bead seat is different, thereby when ink being applied to the different ballpoint pen of two kinds of ball diameters, there is significant difference in the stability of writing that ink shows, because both gaps are different.

For above-mentioned prior art, be necessary to be improved, the applicant has done good try and experiment repeatedly for this reason, has finally formed technical scheme described below.

Summary of the invention

Task of the present invention be to provide a kind of contribute to improve write feel oilness and comfortableness, be conducive to meet writing requirements, be of value to the low temperature resistant super lubricate oil base ink of avoiding the fastidious property of different ball diameters and having the ballpoint pen of the anti-bleed performance of being convenient to embody excellence to use under low temperature environment.

Task of the present invention completes like this, the low temperature resistant super lubricate oil base ink that a kind of ballpoint pen is used, and it is to consist of the raw material of below counting proportioning by quality %:

Described organic solvent is glycerine, Uniflex DBS, 2-methyl 2,4 pentanediols or dioctyl sebacate; Described tinting material is direct red 28 ^#, solvent yellow 2 ^#, solvent yellow 34 ^#, solvent red 1 ^#or alkali green 4 ^#; Described resin is esterase, phenyl aldehyde resin or Zelan 338; Described viscosity modifier is PVB15 or PVB100; Described thixotropic agent is hydrogenated castor oil or EBS: described additive is the agent of BYK104S distributes ink.

Technical scheme provided by the invention is due to material choice and reasonable ratio, thereby in the time of 25 ℃ and shearing rate 500S ^-1time viscosity be 500-3000mpas, the viscosity of shearing rate when 5S-1 is 1000-5000mpas, there is excellent oilness and make comfortable writing, there will not be broken string, while writing at 10 ℃ of envrionment temperatures, ink supply is smooth and easy, to ball diameter, is that the ballpoint pen of 0.5 ㎜ and 0.7 ㎜ is all applicable and there will not be bleed phenomenon.
