Description
Technical field
The invention belongs to polymeric material field, specially refer to a kind of high-resolution code-spraying printing ink and preparation technology thereof.
Background technology
Along with expanding economy, countries in the world have all been formulated the law in serial commodity and trade mark field successively, stipulate that clearly various products must indicate date manufactured, lot number and classification identification marking.And on large-scale pipeline, these contents that often change can't be solved with traditional printing process, if method is printed by hand, efficient is extremely low, and is of poor quality, and with the method for pasting non-setting adhesive, and cost is high, be prone to peel off, and are forged and copy easily.
Begin to adopt digitizing ink-jet coder to identify at present abroad, this method speed is fast, cost is low, legibility, easy and simple to handle.And owing to be the noncontact spray printing, therefore applicable to the sign of different shape product.
Ink jet printing is released in nineteen fifty-one by Siemens Company, goes through semicentennial development and has reached suitable level, and particularly recent, quick, high-quality ink-jet printer is applied to various production fields gradually.The ink particulate that the utilization of digitizing ink-jet coder is charged, through the high-voltage electric field deflection principle, pattern, literal and the number on various body surface spray printings, in computer, preset.This product widespread use packing of product industry (like industries such as food, beverage, drinks and medicine) and product itself; Promptly on product, mark its specifications and models etc.; Make it become a part of content of product itself, mainly be distributed in industries such as electronic devices and components, electric wire, material of construction.
The medium of ink jet printing can be divided into two kinds of ink-jet printing ink and code-spraying printing inks.The employed solvent of ink-jet printing ink is main with water, cooperates a small amount of organic solvent, and used tinting material mainly contains two types of pigment and water-soluble dyes.The color fastness to water of pigment is better than dyestuff, but poor stability possibly cause spray nozzle clogging.Though fast light, the color fastness to water of dyestuff are not so good as pigment, type of dye ink is difficult in nozzle and printing head, causing obstruction.The ink printed mode is mainly used in the printing of paper base material, and its shortcoming is a poor adhesive force, and rate of drying is slow, and diffusion is big, and resolving power is low etc.
The scope that ink-jet ink is used is much then extensive, its high speed, and high resolution, the character of height endurability also will obviously be superior to ink.Ink-jet ink also is divided into two kinds of pigment style and dye-types, and wherein the pigment style product is mainly used in the application of the low kind of resolving power, and such as tr, bag etc., these have all well domesticized.But because the needs of electronics, building and high-grade packing industry, this just needs the dye-type code-spraying printing ink, to reach higher resolving power, adhesive ability, tolerance etc.The continuous expansion of foreign trade scale objectively requires Chinese commodity sign and recognition technology and international standard to integrate with, and the application of digitizing code spraying technology is increasingly extensive and universal to its requirement also raising thereupon.
The digitizing ink-jet technology is because its technological singularity requires printing ink certain specific conductivity must be arranged to satisfy electronically controlled needs; Binding property is arranged preferably to guarantee strong sticking power being arranged on packing of product surface; Tinting material is bright-coloured, good weatherability; Spray printing is smooth, the rapid drying of spray printing mark.But along with continuing to bring out of improving constantly of requiring of product applications and new purposes, existing code-spraying printing ink research can not be satisfied existing technical requirements of using fully, such as higher adhesive ability, and higher resolving power and better fineness stability etc.In order to address these problems, the summary of the invention of this patent is the high adhesive ability that extensively is suitable for that special matrix resin of application and dyestuff stabilising system are realized code-spraying printing ink, very high resolving power and fabulous fineness stability.
