Abstract

The invention discloses a high-modulus environment-friendly glass fiber and a processing technology thereof, and belongs to the field of inorganic nonmetallic materials. The method comprises the following steps: firstly, treating glass fibers by using a silane coupling agent and bovine serum albumin to prepare high-surface-activity glass fibers, then carrying out modification by using halohydrocarbon modified lignosulphonate, adding n-dodecylamine solution modified aminated potassium tetratitanate to prepare a treating agent adsorbed on the surface of the high-surface-active glass fiber, mixing the treating agent with the high-surface-active glass fiber, then carrying out filtering and drying to obtain a blank, and finally carrying out high-temperature carbonization on the blank at a certain temperature to prepare the high-modulus environment-friendly glass fiber. The high-modulus environment-friendly glass fiber prepared by the invention has relatively high tensile modulus and excellent alkali resistance.
