Abstract

The invention discloses basalt fiber with high breaking strength, and relates to the technical field of fiber processing. The basalt fiber is formed by preparing a basalt fiber initial material through nanosilicon dioxide modified basalt mineral powder, and then performing in situ amidoximation modification on the basalt fiber initial material. The basalt fiber has better breaking strength and impact strength.

Description

Technical field [0001] The invention belongs to the technical field of fiber processing, and specifically relates to a basalt fiber with high breaking strength. Background technique [0002] Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is a basalt rock material composed of oxides such as silica, alumina, calcium oxide, iron oxide and titanium dioxide. Drawn. The production process of basalt fiber determines that it produces less waste and has little environmental pollution. After the product is discarded, it can be directly degraded in the environment without any harm, so it is a veritable green and environmentally friendly material. my country has listed basalt fiber as one of the four major fibers (carbon fiber, aramid, ultra-high molecular weight polyethylene, and basalt fiber) to be developed and realized industrialized production. Continuous basalt fibers have been widely used in fiber-reinforced composite mater...
