Anti-static coating carton and preparation method thereof

Abstract

Anti-static coated carton and its preparation method, using special imported equipment to achieve precise control of different coating amounts, coating anti-static coating on the inner paper of the carton, and then pressing the anti-static coating part into it through high temperature (about 170°C) and high pressure A new material layer (2) is formed in the superficial layer of fiber of the cardboard (3), and the antistatic coating forms a new antistatic protective film layer (1) on the surface of the cardboard. Control the pressure between different helical rods and the cardboard coated with antistatic coating to achieve quantitative coating of antistatic coating, which can easily reach 10 3 The Ω grade makes the insulating linerboard become a static dissipative material or a static conductive material. When the package is subjected to harsh transportation environments such as high temperature and high humidity, vibration and shock, the anti-static carton can not only protect the contents from electrostatic damage, but also has stable electrostatic protection performance and is not easy to fall off. And it has the advantages of remarkable effect, convenient production, low cost and the like.

Description

technical field [0001] The invention relates to an antistatic coated carton and a preparation method thereof, belonging to the technical field of packaging products, in particular to a packaging carton capable of electrostatic protection. Background technique [0002] With the rapid development of the electronics industry, products are highly refined, miniaturized, and integrated, resulting in higher and higher sensitivity to electrostatic induction, that is, they are more susceptible to static interference, such as electronic tubes, integrated circuit boards, electronic connection components, and so on. In the process of production, handling, storage, transportation, and use, electrostatic voltage generated by friction, impact, contact, and separation is likely to affect product technical parameters, reduce stability or even cause product failure, so electrostatic protective packaging is particularly important. Starting from the principle of electrostatic discharge (ESD) pr...

AI Technical Summary

Problems solved by technology

[0003] The anti-static corrugated boxes currently on the market are basically printed with anti-static ink on the surface of the carton by a printing machine. Their defects are: the bonding force between the ink and the surface of the carton is poor, the printing layer is uneven, and the thickness cannot be controlled.

The main conductive component of these inks is carbon particles. After printing, the carbon particles in the ink are easy to fall off from the surface of the carton. The fall of carbon particles, but it is the barrier of this layer of "overprint ink", which makes the antistatic performance significantly lower, resulting in the highest antistatic index can only reach 10 5 Ω

In addition, the ink itself contains water, and there are problems such as unstable quality after the corrugated box absorbs water.
