Problems solved by technology

For example, adding silica to aramid fibers can increase the dielectric constant of paper and enhance the insulation performance of paper, as well as adding special functional materials such as zirconia, metal oxide powder, carbon black and other nanomaterials to the paper. Aramid paper is used to improve its performance in one aspect, but nanoparticles are prone to agglomeration due to their small size and high surface energy. These nanomaterials are prone to uneven distribution in paper, which can affect the performance of paper in severe cases Therefore, choosing a nano-material that is not easy to agglomerate, easy to disperse, and has excellent performance to enhance and modify meta-aramid paper is very helpful for improving the mechanical properties and dielectric properties of meta-aramid paper.

Abstract

A meta-aramid paper containing nanometer diamondene is mainly made of a basic raw material, polyoxyethylene and nanometer diamondene, the basic raw material is prepared from 30-60 parts by weight of meta-aramid chopped fibers and 40-70 parts by weight of meta-aramid pulp meal, the use amount of polyoxyethylene is 0.3-0.6% of the amount of the basic raw material, and the use amount of the nanometer diamondene is 2-10% of the amount of the basic raw material. The invention further discloses a making method of the meta-aramid paper containing nanometer diamondene. The meta-aramid paper made in the invention has the advantages of good tensile strength, excellent insulation property, good tear resistance and good wear resistance, and can be applied to the insulation fields of generators, motors, transformers and battery diaphragms, and non-main bearing parts of trains, ships, aircrafts.

Description

technical field [0001] The invention belongs to the technical field of special paper preparation, and in particular relates to a meta-aramid paper containing nanodiamondene and a preparation method thereof. Background technique [0002] In the 1960s, the DuPont Company of the United States invented the high-performance fiber meta-aramid with high temperature resistance and flame retardancy, and developed meta-aramid paper based on this, which has high strength, high modulus, low deformation, and It is a high-tech industrial paper with excellent properties such as high temperature and corrosion resistance. It is also a special insulating paper and structural material paper with high added value. It is recognized as the best insulating material in the world. Utilizing the good insulation properties of meta-aramid paper, it can be applied to generators, motors, transformers, battery diaphragms, etc., and its excellent mechanical properties can be applied to non-important stress...
