The environmental-friendly oil-based ink disclosed by the invention ensures the human body safety, meets the requirements of environmental friendliness and safety, is contribute to reduction of the constant pressure of a book to ensure smoothness, is favorable to improvement of oil bleeding resistant property at high temperature and high humidity can obtaining good viscosity regulation effect and is enhanced in the fixation degree and water resistance therefore.

Description

The environment-friendly oil-based ink that ballpoint pen is used

Technical field

The invention belongs to writing ink technical field, be specifically related to the environment-friendly oil-based ink that a kind of ballpoint pen is used.

Background technology

In order to protect aggravating circumstances increasingly; and in order to ensure human-body safety; European Union has promulgated the general requirement (EN71part9-2005) of organic compound; specify the following migration total amount that is present in the toxic compounds in toy or toy material: contact, absorb possibility, skin contact, eye contact with mouth and suck, and writing implement oil base ink has been contained in this requirement.But, at present general writing implement is generally difficult to reach the requirement of EN71part9-2005 as ballpoint pen oil base ink, because the oil base ink that the ballpoint pen in prior art is used is made up of components such as tinting material, resin and organic solvents, wherein: tinting material is alkaline purple 3, Xylene Red 73#, Sudan red, solvent yellow 34#, direct red 28#, solvent yellow 2 #, solvent red 1#, alkali green 4#, solvent orange 2 #, Victoria Blue B, oil black nigrosine, alkaline rhodamine B and the modification rhodamine b extra 500 6DGN etc. that contain forbidding aromatic amine infringement HUMAN HEALTH; Resin is that the control of dihydroxyphenyl propane, sanitas is difficult to meet the requirements of epoxy resin, Synolac; Organic solvent is such as phenylcarbinol, ethylene glycol phenyl ether, ethylene glycol monobenzyl ether, propylene glycol phenylate and the propylene glycol list benzyl oxide etc. that phenol content exceeds standard.

In disclosed patent documentation, can be seen in the technical intelligence of the oil base ink that ballpoint pen uses, as CN101305062A recommends to have " for the oil-based ink water composition of writing implement and the writing implement of ink as described in use ", oil base ink comprises solvent and tinting material, solvent uses monohydroxy-alcohol, polyvalent alcohol and glycol ethers, tinting material is selected from pigment and/or dyestuff, and this patent scheme is used embodiment Environmental Safety and do not had referential meaning for overcoming foregoing problems.And for example CN102002286B provides " oiliness ball pen ink in a kind of environment-friendly type ", because this patent has been used epoxy resin, thereby the control of dihydroxyphenyl propane, sanitas is difficult to reach requirement.

Summary of the invention

Task of the present invention is to provide a kind of environment-friendly oil-based ink that environmentally friendly and the harmless and safe ballpoint pen that is met EN71part9-2005 requirement is used that contributes to embody.

Task of the present invention completes like this, the environment-friendly oil-based ink that a kind of ballpoint pen is used, and it is to be made up of the raw material of below counting proportioning by quality %:

Organic solvent 60-70%;

Tinting material 15-20%;

Resin 15-30%,

Described organic solvent is environment-friendly type solvent, and described tinting material is environment-friendly type matching stain; Described resin is environmental protection type resin, described environment-friendly type solvent is octyl adipate, Uniflex DBS or glycerine, described environment-friendly type matching stain is Basic Blue 3 34, Acid Black 1 94, acid China ink 210 or direct fast red F3B, and described environmental protection type resin is polyketone resin or xylene resin.

Technical scheme provided by the invention has used environment-friendly type solvent, tinting material to select to have used environment-friendly type matching stain and resin to select with environmental protection type resin due to organic solvent is selected, thereby contribute to embody to the friendly of environment and ensure human-body safety, meet the Environmental Safety requirement that EN71-9-2005 specifies.Because the quality % content of organic solvent in oil base ink is selected rationally, thereby not only contribute to alleviate book constant-pressure and ensure smoothness, and be conducive to improve the anti-bleed performance under hot and humid; Because the quality % content of resin in oil base ink is selected rationally, thereby the good adjustment effect to viscosity can not only be obtained, and degree of fixation and the water tolerance of oil base ink can be improved.

Embodiment

Applicant by organic solvent the consumption in oil base ink be chosen to be 60-70% be through experiment repeatedly determine, because in the time being greater than 70%, can reduce the anti-bleed performance of oil base ink under High Temperature High Pressure, there is ink leak phenomenon, write otherwise there will be the phenomenon that pressure is large in the time being less than 60%, making to write and lose smoothness; The stability decreases of oil base ink in the time that the quality % content of tinting material in oil base ink is greater than 20%, and in the time being less than 15%, coloured light is thin out, makes lines lose the full interrupted style of calligraphy characterized by hollow strokes phenomenon that even occurs; In the time that the quality % content of resin in oil base ink is greater than 30%, can obviously increase and write pressure, make to write effort, in the time being less than 15%, easily under High Temperature High Pressure, there is bleed, and by the quality % content of resin be chosen in 15-30% scope to adjusting viscosity, improve degree of fixation and water tolerance and all there is excellent effect.

Embodiment 1:

The environment-friendly oil-based ink that ballpoint pen is used is made up of the raw material of below counting proportioning by quality %:
