The environmently-friendly exterior wall thermal insulation texture coating was prepared by using of the flexible pure acrylic emulsion,hydrophobic hollow glass beads,aerogel and reflective thermal insulation color paste.The influences of the selection and dosage of glass beads,aerogel,resin and reflective insulating pigment paste on the thermal insulation performance of the film were discussed.The experiment results showed that when the dosage of 20〜60 mesh glass beads was 25.0%〜30.0%,the dosage of aerogel was 1.5%〜2.0%,the dosage of resin was 35.0%〜40.0%,and the dosage of reflective and heat-insulating color paste was no less than 2.0%,the comprehensive performance of the coating film was best.
