High-strength mica paper and method for preparing same

Abstract

The invention discloses high-strength mica paper. A method for preparing the high-strength mica paper includes producing pulp from, by weight, 200-300 parts of mica sheets, 36-45 parts of polyethylene-based resin, 10-25 parts of asbestos, 5-10 parts of cationic starch, 4-10 parts of ethylene diamine tetraacetic acid and 100 parts of water and then manufacturing the high-strength mica paper with the pulp. The high-strength mica paper and the method have the advantages that the high-strength mica paper is extremely high in mechanical strength, and the shortcoming of poor mechanical strength of existing mica paper in application procedures can be overcome.

Description

technical field

[0001] The invention relates to mica paper, in particular to a high-strength mica paper and a preparation method thereof. Background technique

[0002] Mica is a general term for a class of hydrous aluminosilicates. Mica has excellent properties such as insulation and high temperature resistance, and is widely used in coatings, paints, fire protection and electrical industries. Among them, making mica into mica paper is one of the most widely used mica applications.

[0003] At present, mica paper has all the varieties corresponding to sheet mica products. The industry mainly uses the insulation and heat resistance of mica paper, as well as its acid and alkali resistance, to be used as insulating materials for electrical equipment and electrical equipment. However, the mechanical strength of mica paper needs to be further improved. Contents of the invention

[0004] The object of the present invention is to provide a high-strength mica paper, which has h...
