Description

Environment-friendly oil-based ink

Technical field

The invention belongs to writing ink technical field, be specifically related to a kind of environment-friendly oil-based ink.

Background technology

In order to protect aggravating circumstances increasingly; and in order to ensure human-body safety; European Union has promulgated the general requirement (EN 71 part 9-2005) 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 the general requirement of this organic compound has contained writing ink.But, at present general writing implement is generally difficult to reach the requirement of EN 71 part 9-2005 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 oil-based ink water, 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 ", and this patent is owing to having 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 and contributes to embody environmentally friendly and can ensure the environment-friendly oil-based ink of human-body safety.

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

Environment-friendly type organic solvent 40-65%;

Environment-friendly type tinting material 10-55%;

Environmental protection type resin 15-45%,

Described environment-friendly type organic solvent is poly(oxyethylene glycol) 400, Polyethylene Glycol-600, cetomacrogol 1000, polypropylene glycol 400, polypropylene glycol 600 or polypropylene glycol 1000, and described environment-friendly type tinting material is alkali red 1:1 2, Victoria Blue B, acid green 81, ACID BROWN 98, ACID BROWN 165, acid black 172 or acid black 2 42; Described environmental protection type resin is phenyl aldehyde resin or polyketone resin.

Technical scheme provided by the invention has been used environment-friendly type organic solvent, environment-friendly type tinting material and environmental protection type resin owing to selecting, thereby contributes to embody to the friendly of environment and ensure human-body safety, meets the Environmental Safety requirement that EN 71part9-2005 specifies.Embodiment

Applicant by environment-friendly type organic solvent the consumption in environment-friendly oil-based ink be chosen to be 40-65% be through experiment repeatedly determine, because in the time being greater than 65%, 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 40%, making to write and lose smoothness; The stability decreases of oil base ink in the time that the quality % content of environment-friendly type tinting material in environment-friendly oil-based ink is greater than 55%, and in the time being less than 10%, 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 environmental protection type resin in environment-friendly oil-based ink is greater than 45%, 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 environmental protection type resin be chosen in 15-45% scope to adjusting viscosity, improve degree of fixation and water tolerance and all there is excellent effect.
