Abstract
- Abstract With soft-touch, lightweight, excellent temperature resistance and insulating performance, aramid mica paper is widely used in special motors 'transformers and other electrical equipments. In this paper, aramid mica paper was prepared by using white mica, meta-aramid chopped fiber and meta-aramid fibrid as skeleton and bonding components respectively. The effects of aramid fibers ratio, dispersant dosage, mica content and mica particle size on mechanical properties, insulating properties, micro-structure and temperature resistance of paper were studied. The results showed that the optimal process parameters were as follows: the mass ratio of fibrid to chopped fiber was 7:3 the amount of PEO was 0.5wt%, the mass fraction of mica was 50 wt%, and the size of mica was 120~150μm.
