Abstract

The invention discloses a preparation method for cellulose composite paper, belonging to the technical field of functional materials. The method of the invention comprises the following steps: firstly, mixing carbon nanotubes, a surfactant and water ultrasonically, and then shearing a dopamine solution and a defoaming agent at a high speed to obtain a dispersion; subjecting original softwood pulpfibers and water to mixing, soaking and beating successively, then adding a modification additive, vegetable oil, polyol, pretreated carbon black, starch, the dispersion, plant essential oil, polyisocyanate, carrying out emulsification and shearing, and adding ammonia water and a calcium chloride solution at the same time so as to obtain mixed slurry; pouring the mixed slurry into a vacuum suctionflask, and successively carrying out suction filtration, compaction and drying so as to obtain the cellulose composite paper. The cellulose composite paper provided by the invention has excellent electrical conductivity and electromagnetic shielding properties.

Description

technical field [0001] The invention discloses a preparation method of cellulose composite paper, which belongs to the technical field of functional materials. Background technique [0002] With the rapid sweep of the third industrial revolution across the world, comprehensive progress in science and technology, continuous breakthroughs in electronic and electrical technologies, various electronic instruments and home appliances have become increasingly popular in people's daily life and work, making our lives more convenient and social. more progress. While electronic and electrical equipment serve human life, they also generate electromagnetic interference (EMI). Electromagnetic waves are an important way we use to transmit information and energy. However, when we use electromagnetic waves to serve our lives, we also generate electromagnetic radiation pollution. Electromagnetic radiation pollution is an invisible form of pollution. Different from traditional forms of poll...
