Abstract

The invention provides a high-cleanliness washing-resistance alcohol-resistant multicolor antistatic packaging material and a preparation method thereof. The preparation method includes following steps: (1), preparing deionized water and isopropanol into a diluent; (2), adding PEDOT:PSS stoste into the diluent, and adding delustering waterborne polyurethane resin to obtain a mixture A (3), addingnano-scale waterborne dye into the mixture A in the step (2) to obtain a mixture B; (4), sequentially adding a flatting agent, a wetting agent and a slipping aid into the mixture B, and stirring wellto obtain polymer waterborne conductive liquid; (4), print-coating the conductive liquid prepared in the step (3) on the surface of a plastic material, and drying the material after being coated to obtain the packaging material. The packaging material prepared by the method has multiple functions of resisting to static electricity, washing and wiping and multicolor recognition, thereby having wideapplication value.

Description

technical field [0001] The invention belongs to the technical field of new materials, and specifically relates to a new type of packaging material used for the transportation turnover of electronic component products and the special packaging requirements in the assembly process. Background technique [0002] The existing traditional technology is to pass ordinary polymer antistatic coating liquid through a coating machine and coat the surface of the material, so as to realize the transformation from ordinary packaging materials to antistatic packaging materials. Solve the customer's antistatic requirements for packaging materials. [0003] However, due to the increasing requirements of customers for product quality control, one is to require packaging materials to have rich colors so that the classification management of color identification can be effectively carried out; the other is to require cleaner packaging materials, which need to be subjected to repeated ultrasonic...
