Abstract

The invention relates to high-zirconium alkali-resistant glass fiber surface-reinforced short-cut felt and a production method thereof, and belongs to the technical field of alkali-resistant glass fiber production. The method mainly solves the problems that existing medium-alkali and alkali-free glass fibers are poor in alkali resistance and cannot be applied to reinforced cement concrete. The felt is mainly characterized by comprising 55-64% of SiO2, 13.8-17.5% of ZrO2, 1.0-3.5% of TiO2, 4-7.0% of CaO, 11.0-13.5% of NaO2, 1.0-2.5% of K2O, 0-0.3% of Al2O3 and 0-0.2% of Fe2O3, and the felt is produced in the steps that high-zirconium alkali-resistant glass fiber filaments with the diameter of 7-9 micrometers are cut into filaments with the length of 50-75 mm, then the filaments are evenly distributed in multiple dimensions and then bonded through a powder adhesive or an emulsion adhesive, and then curing and drying are conducted. The method solves the problems that the alkali-resistant glass fibers are irregular in spray yarn distribution and poor in homogeneity, the durability can reach 60 years, and the half-life period is up to 100 years.

Description

technical field [0001] The invention belongs to the technical field of production of high-zirconium alkali-resistant glass fiber products. In particular, it relates to a production process research, felt binder research, and application technology research of using high zirconium alkali-resistant glass fiber to produce high zirconium alkali-resistant glass fiber surface reinforced chopped strand mat. Background technique [0002] At present, there are mainly glass fiber mats made of medium-alkali and non-alkali glass fibers in China, which are mainly used to strengthen resins and produce FRP products. Due to the poor alkali resistance of medium-alkali and non-alkali glass fibers, they cannot be used in reinforced cement to make building components and products. The invention of high zirconium alkali-resistant glass fiber surface-reinforced chopped strand mat overcomes the weakness of medium-alkali and non-alkali glass fiber, and makes full use of the excellent alkali resist...
