Problems solved by technology

Antistatic film materials are not suitable for the packaging of large devices, which has limitations. If paper packaging materials can be made into materials with certain antistatic properties, they can be developed into a variety of large, medium and small packaging products. Its application fields Very wide, and the antibacterial properties of existing paper packaging materials are poor, resulting in short service life

Abstract

The invention discloses a preparation method of anti-static carbon fibre functional composite paper. The preparation method comprises the following steps: crushing wheat straw and waste paper, addingwater, standing, draining, soaking in a potassium hydroxide solution, steaming in a manner of insulating from water, drying, performing wet ball milling, concentrating, pulping, and performing papermaking to obtain blank paper; mixing waste paper and the potassium hydroxide solution, standing at a room temperature, then heating and stirring, performing suction filtration, washing a filter cake, drying to reach constant weight, adding a sepiolite powder, dodecyl ammonium chloride and silver nitrate solution, regulating the pH value of the system to be 6.4 to 6.8, stirring uniformly, adding a silane coupling agent KH-550, stirring uniformly, performing ultraviolet irradiation treatment, filtering, washing with deionized water, drying, and crushing to obtain a composite antibacterial agent; uniformly mixing graphite, carbon black, a coconut shell carbon powder and the composite antibacterial agent, adding an anti-static agent, a dispersing agent and an adhesive, mixing uniformly, concentrating, coating the surface of the blank paper with the mixture, drying, applying the adhesive to double surfaces, drying a finished product, and rolling paper.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a preparation method of antistatic carbon fiber functional composite paper. Background technique [0002] As electronic products continue to change people's production and life, electronic semiconductor products are prone to generate and accumulate static electricity during long-term transportation and storage, which has a certain impact on the quality and service life of electronic products. The packaging of products puts forward higher requirements, which can prevent static electricity, and the market demand for packaging materials with higher strength is strong. [0003] The packaging of electronic products usually uses antistatic film as the inner packaging, and then uses cartons as the outer packaging and transportation packaging materials. If the permeability of paper packaging materials can be improved, water molecules in the air can be used to a certain extent, The t...
