Preparation method of hybrid size for improving basalt fiber performance and modification method

Abstract

A process for improving the performance of basalt fibers features that an ultrasonic forced continuous coating technique is used for coating hybridized slurry on the surface of each basalt fiber to improve its tension strength and the resistance to high temp. A process for preparing said hybridized slurry is also disclosed.

Description

【Technical field】

[0001] The invention belongs to the field of fibers and their composite materials, and in particular relates to a basalt fiber surface modification slurry and a method for modifying the basalt fiber. 【Background technique】

[0002] Basalt fiber is a new type of inorganic reinforcing material. It is made of a single basalt ore. Its raw material is cheap and has abundant reserves, which has an outstanding price advantage. Basalt fibers are mainly composed of SiO 2 、Al 2 o 3 , Fe 2 o 3 , CaO, MgO, K 2 O, TiO 2 It has excellent mechanical, chemical and thermodynamic properties, especially in high temperature resistance, chemical medium resistance and heat insulation, insulation, sound insulation performance, etc. Compared with traditional glass fiber, it has obvious advantages. In addition, basalt fiber products will not release toxic substances in the air and water media, and become the parent material of the soil after degradation, which is environment...
