Abstract

The invention discloses a non-asbestos composite fiber and a preparation method of the on-asbestos composite fiber, and belongs to the technical field of chemical material manufacturing. The non-asbestos composite fiber has the main technical characteristics that: the fiber is composed of the following raw material compositions in percentage by weight: 62-80% of a fiber material, 17-34% of a powder material, and 3-6% of a modifier, wherein the fiber material is a non-natural fiber material subjected to high-temperature treatment, the powder material is selected from talcum powder, bentonite, vermiculite and mica powder and the like in silicate materials, the particle size of the powder material enables the powder material to achieve 100% of passing rate at 100 meshes, and the modifier is a polymer resin or a combination thereof. The composite fiber disclosed by the invention is simple in material production process and low in cost, and has good comprehensive performances such as low shot content, small fiber diameter and high fiber strength and the like; and the used fiber does not contain asbestos and asbestos fiber, therefore, the non-asbestos composite fiber is nonpoisonous, and has no harm to the human body and environment. Therefore, both in production and use, the safety and reliability can be ensured, so the non-asbestos composite fiber is an environmental-friendly novel composite fiber material.

Description

1. Technical field [0001] The invention relates to a composite fiber used for friction materials and a preparation method thereof, in particular to an asbestos-free composite fiber and a preparation method thereof. The invention belongs to the technical field of chemical composite material manufacturing. 2.
