Problems solved by technology

[0003] However, most of the existing coatings are solvent-based coatings, which seriously pollute the environment. With the strengthening of environmental protection awareness, more and more people begin to pay attention to environmentally friendly conductive, antibacterial and other functional types, but there are few reports currently compatible with antibacterial properties and conductive properties and applied to corrugated board coatings

Abstract

The invention discloses a preparation method of a multifunctional corrugated board. The method comprises the following steps: (1) preparing an antimicrobial solution; (2) preparing a conducting solution; (3) mixing the antimicrobial solution and the conducting solution, sequentially adding a defoaming agent, a thickener and a modifier, and dispersing at high speed to obtain the antimicrobial antistatic paint; and (4) brushing the antimicrobial antistatic paint on a corrugated board to prepare the multifunctional corrugated board. The conducting filler in the paint used by the corrugated board can enable the conducting structure to be more compact and form a favorable interlayer communicating structure, and the conducting channels are smoother, thereby lowering the resistivity of the paint; and the surface resistivity is adjustable within the range of 10<2>-10<5> ohm. The antimicrobial composite material integrates the antimicrobial property of silver particles and titanium dioxide, and has the advantages of better antimicrobial effects and longer antimicrobial time than the single silver nano antimicrobial agent. The conducting filler and antimicrobial composite material are reasonably matched, so that the corrugated board has the antistatic characteristic and enduring antimicrobial property.

Description

technical field [0001] The invention relates to a method for preparing a multifunctional corrugated cardboard. Background technique [0002] In recent years, the electrostatic protection packaging market has been expanding, but the form of packaging materials is very single, that is, using anti-static plastic bags as inner packaging, and then using cartons or plastic boxes as transportation packaging is the main packaging form at present, but for the protection of large and medium-sized products The packaging is not suitable, and the cost is high and the operation is complicated. It is of great engineering value to research and develop new corrugated cardboard and cartons with static conduction function, and its industrialization prospect is very broad at the same time. At present, it is convenient and quick to apply conductive paint on the surface of corrugated cardboard, and the cost is low. [0003] However, most of the existing coatings are solvent-based coatings, whic...
