A special sizing agent for cement-based material reinforced basalt fiber and its preparation method

Abstract

The invention discloses a cement-based material reinforced basalt fiber special impregnating agent, and a preparation method thereof. The cement-based material reinforced basalt fiber special impregnating agent comprises, by weight, 40 to 60 parts of a film forming agent, 5 to 15 parts of a coupling reagent, 1 to 5 parts of a lubricating agent, 10 to 20 parts of a modifying agent, and 30 to 50 parts of water; the modifying agent comprises a soluble phosphate, a strong base, and a dissoluble silicate at a mass ratio of 2-4:1-3:3-6. The cement-based material reinforced basalt fiber special impregnating agent is used for impregnating and fiber surface modifying at the same time, fiber surface roughness is increased, and a large amount of active site and active groups are formed on fiber surfaces, so that chemical bonding and mechanical riveting of basalt fiber with a cement-based material are realized, an integrated stable whole body is formed by basalt fiber and the cement matrix, reinforcing effect on the cement-based material is obvious, reinforcing effect is excellent, and popularization and application of basalt fiber in the cement-based material is promoted.

Description

technical field [0001] The invention relates to the field of basalt fiber wetting agent, in particular to a special wetting agent for reinforcing basalt fiber with cement-based materials 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 en...
