Abstract
An environmental-protective printing ink with methyl-carbonate and dimethyl sulfoxide as mixed solvent in proportion of 1:0.20-0.30 is harmless. The printing ink consists of mixed solvent 35-55 proportion, resin 15-40 proportion, latent solvent alcohol 1-15 proportion, rosin modified resin 10-20 proportion, alcohol soluble modified aldehyde ketone resin 5-10 proportion soluble alkyd resin 1-5 proportion and pigment 10-15 proportion. It has excellent adaptability and has no harm to human body.
Description
Technical field
The invention belongs to the printing-ink technical field, be specifically related to a kind of solvent-based environmentally friendly printing ink.
Background technology
Printing-ink is the pulpous state colloid that is mixed by material homodisperse such as colorant, low-melting ink vehicles.The low-melting ink vehicle of solvent type ink is made of solid resin and a large amount of volatile organic solvent.After solid resin is dissolved in the solvent, colorant is dispersed in the low-melting ink vehicle, printing ink is printed to stock, the rapid volatile dry conjunctiva of solvent.Organic solvent in the existing printing ink all has in various degree pollution and infringement to environmental health and personnel health, and in the dried ink lay toward the remaining nuisance of contact, can not satisfy the requirement of food product pack and cigarette-brand printing, therefore prevent public hazards and guarantee that environmental health becomes the key subjects in the new solvent type ink development.
Methylcarbonate (being called for short DMC) is the environment-friendly Chemicals that are subjected to domestic and international extensive concern in recent years.Since contain in its molecule CH3-, CH3O-, CH3O-CO-,-multiple functional groups such as CO-, thereby have good reaction activity; In addition, DMC in 2000 have passed through the registration of European chemical management board, belong to nontoxic or little chemical product that poisons.The DMC structural formula is (CH3O) 2CO, and molecular weight is 90.08, relative density 1.070, specific refractory power 1.3697; 4 ℃ of fusing points, 90.1 ℃ of boiling points.Be colourless liquid at normal temperatures, have combustibility, be slightly soluble in water but can form azeotrope with water, can with nearly all immiscible organic solvents such as alcohol, ether, ketone; To the metal non-corrosiveness, available work durm splendid attire is stored.
Dimethyl sulfoxide (DMSO) (being called for short DMSO) is very important aprotic polar solvent, as a kind of important fine chemical product, is widely used in industries such as medicine, agricultural chemicals, refining of petroleum, organic synthesis.Still there are many new purposes developing or be about among the exploitation at present.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, providing a kind of is the environment-friendly ink of mixed solvent with methylcarbonate and dimethyl sulfoxide (DMSO).
Product environment-friendly ink of the present invention includes solvent, solubility promoter, the resin that can be used for solvent type ink and colorant, it is characterized in that:
Said solvent is the mixed solvent that methylcarbonate and dimethyl sulfoxide (DMSO) are formed, and wherein the weight ratio of methylcarbonate and dimethyl sulfoxide (DMSO) is 1: 0.20～0.30,
Said solubility promoter is an ethanol,
More than the weight proportion of each component be:
30～60 parts of mixed solvents
15～40 parts of resins
1～25 part of solubility promoter
2～25 parts in colorant
Resin in the product of the present invention can be modified resin, natural resin or synthetic resins.Resin can use separately, also can several mixed with resin use.Colorant can be pigment and dyestuff.Can also contain volatile dry type printing ink various auxiliary agents commonly used in the product of the present invention, as lubricant, emulsifying agent, dispersion agent, defoamer, frostproofer, flow agent, softening agent, slip(ping)agent etc.
Product of the present invention is applicable to the printing of the gravure of paper, tinsel, protruding seal, flexo or silk screen etc., and paper compound Lacquer finish is used.When making product of the present invention, can in the scope of above-mentioned prescription, finally determine material and concrete proportionings such as detailed resin according to different printable fabrics, typography.
The screening formulation of product of the present invention is the component that comprises following weight proportion:
The weight ratio of methylcarbonate and dimethyl sulfoxide (DMSO) is 35～55 parts of 1: 0.24～0.26 mixed solvents
10～20 parts of modified rosin resins
5～10 parts of alcohol dissolubility modification aldehyde ketone resins
1～5 part of water soluble alkyd resin
1～15 part of solubility promoter
10～15 parts in colorant
Press the production process of solvent type ink, after dissolving, moistening dispersion, grinding, allotment, promptly can be made into product of the present invention.
Beneficial effect of the present invention: the invention product is solvent with DMC+DMSO, it is except the printing adaptability that possesses traditional solvent type ink, also because its drying process is the crosslinking curing film forming, and can not cause infringement to human body and environment as the vaporization of DMC, the DMSO of solvent, and can not retain nuisance in the China ink layer after solidifying, can reach the food sanitation requirement, so the invention product is a kind of novel environment friendly printing ink.The invention product is widely applicable, production and safe in utilization, and printing process is environmentally friendly, has premium propertiess such as strong adhesion, glossiness height, bright in luster, cold-resistant heat, chemically-resistant thing and good stability in addition.
Embodiment
See following examples:
Embodiment 1.Each raw material takes by weighing by following weight proportion:
