Environment-friendly printing drying promoting powder and preparation method thereof

Abstract

The invention discloses environment-friendly printing drying promoting powder. The environment-friendly printing drying promoting powder is prepared from the following raw materials in percentage by weight: 3 to 5 percent of organic silicon resin, 0.1 to 0.5 percent of a drier and the balance of starch powder. The preparation method of the environment-friendly printing drying promoting powder comprises the following steps: with the starch powder which has no carcinogenicity and is easy to produce and degrade as a base material, and adding the drier into the starch powder. The environment-friendly printing drying promoting powder disclosed by the invention has the advantage that excellent ink-affinity and excellent assimilability with ink are realized; the environment-friendly printing drying promoting powder can be quickly dissolved when meeting with ink; the influence on the gloss and brightness of a printing ink layer is avoided; and the drying of the printing film layer can be accelerated, set-off is avoided and the printing speed, printing quality and production efficiency can be significantly improved. In addition, the environment-friendly printing drying promoting powder hashigh hydrophobicity and relatively high density; the problems such as caking and stacking, nozzle plugging, uneven spraying and dust pollution are avoided, the utilization ratio of the printing spraypowder can be greatly improved, and the cost is reduced; the workshop environment is optimized, harm to a human body is weakened and environmental protection manufacture is facilitated; and the environment-friendly printing drying promoting powder has huge economic benefits.

Description

technical field [0001] The invention relates to an ink printing consumable, in particular to an environmentally friendly and degradable printing auxiliary drying powder. Background technique [0002] In recent years, with the continuous innovation of printing equipment technology, the printing speed of printing machines has been greatly improved. What follows is that the printing film layer is not completely dried, and problems such as back smearing and adhesion between papers appear, which have a great impact on the quality of printed matter, printing speed and printing efficiency. In order to solve this problem, as a very important auxiliary material in printing, printing auxiliary dry powder (spraying powder) is very important for printing production, printing quality and post-processing. In the printing process, the function of printing auxiliary powder (powder spraying) is to prevent the back of the printed matter from being smeared due to the wet ink layer during the ...

AI Technical Summary

Problems solved by technology

At present, the printing powder commonly used in the industry has a low density and is easy to fly powder. In order to avoid the problem of smudging on the back of the printed product, the amount of use is very large, which can easily cause dust pollution and cause great harm to the body of the printing worker. Harm; Secondly, the current printing powder spraying performance is poor. When the humidity of the environment is high, it is easy to absorb moisture and agglomerate in the end storage box, and the use efficiency is low. At the same time, it is easy to block the nozzle, spray unevenly, and cause bubbles to appear on the coating , Open glue and affect the quality of printed matter; Thirdly, the commonly used printing powder spraying has poor particle size and uniformity, resulting in a large amount of powder remaining on the printed matter, rough surface, and poor post-processing, which affects the quality of printing. It will affect the good operation of printing equipment (such as blankets, ink roller systems, delivery systems, transmission machinery, etc.), increase the maintenance time and cost of printing equipment, and cause losses to printing companies
