Description
Technical Field
The invention belongs to the technical field of high molecular fine chemical industry, and particularly relates to black water-based ink with an insulating effect and a preparation method thereof.
Background
A traditional double-sided PE coated paper cup (called double PE paper cup for short) is prepared by uniformly coating a thin polyethylene film layer on both sides of a white cardboard, performing flexography on a printing surface, and finally forming the cup. The process has high water resistance, wear resistance, scratch resistance and other performance requirements on the water-based ink because the ink is exposed, and additional varnish finishing treatment is carried out in many cases, so that the cost is correspondingly increased.
The existing new technology of film-coated paper cup appears, firstly, one side of the white cardboard is printed with the graphic text by using the water-based ink, then, corona treatment is carried out on the blank side and the printing side of the white cardboard (the purpose is to increase the surface tension of paper and an ink layer and improve the adhesive force after film coating), then, the double-sided film coating is carried out by using polyethylene, and finally, the cup is formed. The novel double PE paper cup prepared by the process has the characteristics of migration resistance, water resistance, solvent resistance, wear resistance, scratch resistance and the like naturally because the ink layer is completely sealed between the white cardboard and the polyethylene laminated layer.
The traditional black water-based ink uses pigment carbon black as a colorant, wherein the pigment carbon black has certain conductivity naturally, and the thinner the particle size is, the higher the color concentration is, the thinner the ink layer is and the stronger the conductivity is. In the corona treatment process, the applied high-voltage electricity can instantaneously break through a black coating containing pigment carbon black or other spot-color coatings containing pigment carbon black to form a coating breakdown mark, and when the coating breakdown mark is serious, sparks can be generated to further ignite and burn. The traditional insulating carbon black in the market is mostly used for plastic products such as electric and electronic products. The insulating pigment carbon black can be used for water-based ink, can also meet the basic requirements of low oil absorption value and high blackness, is very expensive, is basically an imported product, and is unstable in goods source. Copper chrome black (pigment black 28) is used as an environment-friendly black colorant with the blackness inferior to that of carbon black, has the characteristics of high blackness, low oil absorption value, high radiation heat exchange efficiency and the like, and is mainly used in the special fields of baking varnish with high temperature resistance, heat preservation coating with infrared reflection and the like. The copper-chromium black has natural physical inertia, the conductivity is far smaller than that of common pigment carbon black, and the copper-chromium black is close to the insulation level of insulating carbon black, so that the process requirements of the novel double PE paper cup can be met.
However, because the specific gravity of copper-chromium black is too large and is as high as more than 5.0, and the chemical inertness is very strong, the stable dispersion of copper-chromium black powder particles is realized by using the traditional dispersing agent sold in the market through the principles of steric hindrance and static electricity elimination, the copper-chromium black powder particles are not layered and precipitated after long-term storage, the difficulty is very high, and the paper cup printing ink also requires low-viscosity printing, so that the anti-sedimentation problem is more prominent.

The common black water-based ink layer using the high pigment carbon black as a colorant not only has obvious spark in the corona process, but also has obvious electric shock mark remained in the printing sample. Whereas the black aqueous ink layer prepared in example 1 was completely free of spark phenomenon and electric shock mark.
From the test results, it can be seen that the copper-chromium black is used as a black colorant to replace the traditional pigment carbon black to be applied to the water-based ink, so that the insulation performance of the black ink layer is greatly enhanced, and no breakdown mark and no spark phenomenon occur when the black ink layer is discharged through a corona machine. And after the copper-chromium black is grafted and polymerized to acrylic emulsion by a cobalt-60 radiation polymerization device, the prepared black water-based ink greatly improves the layering and precipitation problems of high-density copper-chromium black powder in a low-viscosity state.
The foregoing is a detailed description of the embodiments, convenient those skilled in the art are able to make and use the present invention. Those skilled in the art, based on the present invention, should not be subjected to innovative work, but rather should be able to obtain improvements or modifications by means of analysis, analogies or limited enumeration, etc. within the scope of protection defined by the following claims.
