Electrostatic prevented corrugated paper plate coating and preparation method thereof

Abstract

The invention discloses antistatic corrugated board paint and a preparation method thereof. The antistatic corrugated board paint is characterized in that a conductive filler is positioned in a dry box and is dried to constant weight; a coupling agent is sprayed on the conductive filler, is sequentially added with film-forming resin, a mixed solvent and a dispersant and is evenly stirred to form a primary mixture; and the viscosity of the primary mixture after ball milling is regulated through a diluent for the ball milling of the primary mixture so as to obtain the antistatic corrugated board paint. The antistatic corrugated board paint has a more compact conductive structure to form a good interbedded communication structure and has a smoother conductive passage, thereby reducing the resistivity of the paint; the paint conducts through a few conduction mechanisms of a seepage theory, tunnel effect, a field emission theory and a thermodynamics theory; according to different proportioning proposals, the resistivity of the surface of the paint can be adjusted; the method has a simple and feasible process, convenient construction and lower cost, can improve production efficiency and does not generate influence on the prior performances of paperboard, such as mechanical performance and obstruction performance.

Description

technical field [0001] The invention discloses an antistatic corrugated cardboard coating, and also discloses an antistatic corrugated cardboard coating and a preparation method thereof. Background technique [0002] During the transportation of electronic products, it is easy to accumulate static electricity, and electrostatic discharge occurs, resulting in product damage or reduced service life. In recent years, with the extensive use of electronic products, microelectronic components have penetrated into various fields of industry, military affairs, and daily life. The electrostatic sensitivity of microelectronic products has increased with the miniaturization and integration of their products. Therefore, anti-static The demand for packaging is also getting higher and higher, making the market demand and development of anti-static packaging materials and packaging technology extremely rapid in recent years. The so-called anti-static packaging is to use packaging material...

[0004] Publication No. CN1535205A (Application No. 02806720.7) discloses a multilayer packaging material suitable for electrostatic applications. This multilayer structure includes at least one antistatic outer layer and a conductive core layer, selected from an intrinsic polymer A mixture of materials, conductive fillers and a non-conductive matrix polymer, although this method can play a good antistatic effect, but the cost is high, processing is difficult, and large-scale development and application are limited

[0005] Publication No. CN101117498A (Application No. 200610015050.2) discloses a method for preparing an antistatic acrylic paint. The conductive filler is furnace carbon black, but its surface often absorbs a layer of oxygen-containing complexes. These volatiles will cause the carbon black to conduct electricity. In addition, carbon black is used as a conductive filler alone. In actual operation, there are problems such as high viscosity, difficult processing, and high content of the original performance of the polymer.
