Abstract

The invention discloses high-strength aramid paper and a preparing method thereof. The high-strength aramid paper comprises a spunlace nonwoven cloth layer and aramid fiber paper, wherein the spunlace nonwoven cloth layer and the aramid fiber paper are compounded, and the spunlace nonwoven cloth layer is formed by first aramid chopped fiber mutually wound; the aramid fiber paper is composed of second aramid chopped fiber and aramid fibrid mutually wound, part of the first aramid chopped fiber and part of the second aramid chopped fiber are wound mutually, part of the first aramid chopped fiber and part of the aramid fibrid are wounded mutually, and the thickness of the aramid fiber paper is larger than that of the spunlace nonwoven cloth layer. Compared with the prior art, the high-strength aramid paper has the spunlace nonwoven cloth layer formed by first aramid chopped fiber mutually wound, the spunlace nonwoven cloth layer has high mechanical strength, and the service life of the high-strength aramid paper is prolonged.

Description

technical field [0001] The invention relates to a high-strength aramid fiber paper and a preparation method thereof. Background technique [0002] Aramid insulating paper, also known as aramid paper, has good thermal stability, flame retardancy, high temperature insulation and chemical stability, so it is widely used in aerospace, transportation, electronics and other fields. Existing aramid paper is usually composed of para-aramid chopped fibers, meta-aramid pulp and adhesives. Aramid paper has low mechanical strength and is easy to tear, resulting in a short service life. Therefore, It is necessary to provide a new aramid paper to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a high-strength aramid paper with high strength and long service life. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as follows: [0005] A high-strength aramid paper, compr...
