Preparation and Properties Research of Silica Aerogel Composite Materials with Silica Powder
摘要
Abstract
The highly stable silica powder composite materials can effectively improve the defects of the aerogel,such as high brittleness and unstable mechanical properties.Using the sol-gel method under ambient pressure dr-ying,the study prepared high-temperature stable silica aerogel composites with varying silica powder mesh sizes and content.The composite formed by silica micropowder and silica aerogel had good hydrophobicity and large specific surface area(>590 m2/g),and its contact angle and BET specific surface area were the largest when the content of silica micropowder was 9％;when the content of silicon micropowder was 3％～15％,the particle size of the com-posite material tends to increase with the increase of silicon micropowder content.This work establishes an effective method for preparing inorganic matrix silica aerogel composites.The strengthened thermal stability and larger specif-ic surface area broaden their application prospects in fields such as thermal insulation and environmental protection.关键词
