High-strength mica paper and preparation method thereof

Abstract

The invention discloses high-strength mica paper. The high-strength mica paper is prepared through pulping and papermaking from a mica plate, urea resin, glass fiber, polyacrylamide, ethylenediaminetetraacetic acid and water, wherein relative to 100 parts of water by weight, the using amount of the mica plate is 200 to 300 parts by weight, the using amount of the urea resin is 36 to 45 parts by weight, the using amount of the glass fiber is 10 to 25 parts by weight, the using amount of the polyacrylamide is 5 to 10 parts by weight, and the using amount of the ethylenediaminetetraacetic acid is 4 to 10 parts by weight. The high-strength mica paper has extremely high mechanical strength, and makes up the defect that the mica paper is low in mechanical strength in the application process.

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...
