A special sizing agent for polyamide material reinforced basalt fiber and its preparation method

Abstract

The invention discloses a wetting agent special for polyamide material reinforcing basalt fibers and a preparation method of the wetting agent. The wetting agent provided by the invention comprises the following components in parts by weight: 40-60 parts of a film forming agent, 5-15 parts of a coupling agent, 1-5 parts of a lubricant, 10-20 parts of a modifier and 30-50 parts of water, wherein the modifier comprises a nitrate, a strong base and a quaternary ammonium salt at a mass ratio of 2-4: 1-3: 1-4. The modifier is used for modifying surfaces of the fibers while wetting, to improve the roughness of the surfaces of the fibers and form a large number of active sites and active groups, thereby chemically bonding and mechanically riveting to the polyamide material, uniformly and stably integrating with the polyamide material, significantly reinforcing the polyamide material, realizing excellent reinforcing effect, and promoting promotion and application of the basalt fibers in the field of reinforcement of the polyamide material.

Description

technical field [0001] The invention relates to the field of basalt fiber sizing agent, in particular to a special sizing agent for polyamide material reinforced basalt fiber and a preparation method thereof. Background technique [0002] Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material, and it is one of the four high-performance fibers that will be developed in my country in the future. The basalt rock material composed of basalt is melted at high temperature and then prepared by spinning process. Basalt continuous fiber not only has good stability, but also has various excellent properties such as electrical insulation, corrosion resistance, combustion resistance, and high temperature resistance. Moreover, the production process of basalt fiber produces less waste and less environmental pollution. It can be directly transferred to the ecological environment without any harm, so it is a veritable green and environmental ...
