Abstract

The invention relates to modified ultrafine glass fiber cotton with high specific surface area for an AGM partition and a preparation method thereof, belonging to the technical field of functional composite materials. The modified ultra-fine glass fiber cotton is prepared from 85-94wt% of ultra-fine glass fiber cotton, 5 to 12wt% of nano-scale silica powder and 0.5 to 5wt% of processing aids according to mass percentage. The invention also relates to a preparation method of the modified ultrafine glass fiber cotton, the modified ultrafine glass fiber cotton is obtained by compounding the ultrafine glass fiber with the nano-scale silica powder and the processing aids and then drying the modified ultrafine glass fiber cotton. The prepared modified ultrafine fiberglass cotton can be used for preparing the AGM partition with excellent uniformity, tensile strength, resilience, oxygen recombination efficiency and high acid absorption.

Description

technical field [0001] The invention belongs to the technical field of functional composite materials, and in particular relates to a modified ultrafine glass fiber cotton for high specific surface area AGM separators and a preparation method thereof. Background technique [0002] Valve Regulated Lead Battery (VRLA) has won a large market due to its characteristics of no acid mist overflow, convenient use and less maintenance. Ultrafine glass wool separator (AGM) is one of the main materials of VRLA. The improvement of the performance of AGM separator will promote the improvement and development of VRLA performance, and it plays a key role in the development of lead-acid batteries. Due to the advantages of high purity, chemical stability, acid corrosion resistance and high oxidation resistance, AGM separator can effectively realize the sealing of lead-acid batteries, reduce the escape of gas, and provide a guarantee for the safe and efficient use of VRLA batteries. an impor...
