The alkali-resistant glass fiber mesh is woven from alkali-resistant glass fiber textile yarn. Zirconia (content 14.5% or 16.7%) is introduced into the glass fiber composition, the raw material is melted at 1600 ℃, and the surface monofilament is coated with high-molecular water-soluble epoxy resin and coupling agent during the formation of the fiber to meet the mesh cloth. The affinity with alkali-resistant compounds during post-processing, the surface of the mesh cloth is coated with a high alkali-resistant polymer synthetic material again, so that it forms a high toughness and strong alkali resistance on the surface of the mesh cloth. In addition, the fiber itself contains zirconium oxide and titanium oxide, forming a mixed film of zirconium and titanium ions on the surface of the fiber, which can effectively resist the effect of hydrates such as Ca(OH) 2 in the polymer mortar on the alkali-resistant glass fiber mesh. erosion.
