Abstract

The invention discloses a preparation method of rare earth element modified heat-resistant textile. The method concretely comprises the following processes: firstly, soaking volcanic rock in sulfuricacid, filtering, collecting filtrate, adding a hydrogen peroxide solution, stirring and precipitating to obtain a porous silicon-aluminum compound; adding deionized water for dispersing so as to prepare dispersion liquid; dissolving molybdenum powder in a hydrogen peroxide solution, adding anhydrous ethanol, citric acid, a lanthanum chloride aqueous solution and the porous silicon-aluminum compound, stirring and mixing, and carrying out a reaction at a certain temperature to obtain modified filler; mixing the obtained modified filler with styrene-acrylic emulsion, deionized water, corn starch,a silane coupling agent, hydroxyethyl cellulose and butyl phthalate to prepare finishing liquid; finally, finishing textile with the finishing liquid to obtain the heat-resistant textile. The textileprepared by the method is soft and comfortable, excellent in antibacterial property, good in heat resistance and mechanical properties and high in safety.
