Research on Preparation of New Aluminum Silicate Fiber Adiabatic Paper

Abstract

Aluminium silicate fiber is an excellent high-temperature material which is widely used in special paper industry in recent years. Due to its property of hardly interweave into the paper and the low strength of the single inorganic fibers paper, it is difficult to make a general basis weight paper. In response to these issues, the strength of the paper was improved by adding some plant fibers. This study takes advantage of good resistance to high temperature of inorganic adhesive and bonding capacity of organic intensifier. Meanwhile two inorganic adhesives (waterglass and ludox) and one organic adhesives carboxymethy starch (CMS) were used in the process of preparing the aluminium silicate paper. The physical properties and insulation properties of the paper which prepared from the difference conditions were studied. The experiment results showed that the adhesive of waterglass and ludox can improve the properties of resistant to high temperature. The adding dosages were 10% and 7.5ml, respectively. The best ratio of alumina silicate fiber to conifier fiber is 7 to 3.The using of CMS can decrease the amount of the plant fiber and its best usage is 10%.
