Abstract

The invention discloses a special impregnating agent for polycarbonate material reinforced basalt fibers and a preparation method of the impregnating agent. The impregnating agent comprises, by weight, 40-60 parts of film forming agent, 5-15 parts of coupling agent, 1-5 parts of lubricant, 10-20 parts of modifier and 30-50 parts of solvent. The modifier comprises organic acid salt, strong base and carbonyldiimidazole in the mass ratio of (3-6):(2-4):(1-3). The surfaces of the fibers are modified when the modifier is used for impregnating, so the roughness of the surfaces of the fibers is improved, a large number of active groups are grafted, accordingly chemical bending and mechanical riveting capacity between the basalt fibers and a polycarbonate material is improved, compatibility between the basalt fibers and the polycarbonate material is improved, and application and popularization of the basalt fibers in the polycarbonate material reinforcing field are promoted.

Description

technical field [0001] The invention relates to the field of basalt fiber sizing agent, in particular to a special sizing agent for polycarbonate 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 environmen...
