A kind of environment-friendly printing auxiliary dry powder and preparation method thereof

Abstract

The invention discloses an environment-friendly printing auxiliary powder, which is made of the following raw materials in weight percentage: 3-5% of organic silicon resin, 0.1-0.5% of drier, and the rest is starch powder. The preparation method uses starch powder as the base material, which is non-carcinogenic, easy to produce and degrade, and is added to the drier starch powder; the invention has excellent ink affinity, excellent assimilability with ink, and can quickly dissolve when it meets ink. It does not affect the gloss and vividness of the printing ink layer, can accelerate the drying of the printing film layer, avoid smearing, and can significantly improve printing speed, printing quality and production efficiency. And it has good hydrophobicity and high density, avoiding problems such as agglomeration, clogged nozzles, uneven spraying and dust pollution, which can greatly improve the utilization rate of printing powder spraying and reduce costs; optimize the workshop environment and weaken Harmful to the human body, it is conducive to environmental protection manufacturing and 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
