Exterior wall coating was prepared. United States military standard MIL-E-46136ASfor the evaluation of the thermal insulation performance standards. Studied the effects of coating thermal insulation performance factors. The results show that Preparation of the best formula for the thermal insulation coating: silicon content of 40% emulsion, the amount of paint 25% of the total, 200 head of hollow glass bead content was 12.5%, rutile TiO2 content of 15%.Optimization of coating formulations prepared, film thickness 0.2mm, thermal performance testing of its absolute temperature is 22℃, lower than the blank sample 14 ℃.Conventional paint film performance test results show that the performance of coatings meet the national standard GB-T9755-2001.
