Embodiment 1

[0033] A kind of preparation method of nano heat-insulating coating for building, comprises the following steps:

[0034] Step 1. First measure 10Kg of deionized water, then add 20Kg of microcrystalline heat-insulating nano-powder, 3Kg of modified potassium hexatitanate whisker slurry and 15Kg of silicone resin emulsion to fully stir. The stirring speed is 500rpm, and the temperature Raise to 40°C and continue stirring for 1h to obtain the primary mixture;

[0035]Step 2. Add 10Kg of inorganic filler, 5Kg of near-infrared reflective powder, 5Kg of silicon acrylic emulsion, 4Kg of cold pigment and 2Kg of additives to the initial mixture in step 1, and continue mixing. The stirring speed is 600rpm, and the temperature continues to rise Stir to 80°C for 3 hours, and obtain the finished coating after being fully dispersed.

[0036] Among them, the microcrystalline thermal insulation nano powder can be purchased from Huntsman, UK, the near-infrared reflective powder can be purchas...

Embodiment 2

[0039] A kind of preparation method of nano thermal insulation paint for building, it is different from embodiment one, comprises the following steps:

Abstract

The invention discloses nanometer heat insulating coating for buildings, and relates to the field of coating. The nanometer heat insulating coating includes, by mass, 10-20 parts of deionized water, 20-40 parts of microcrystal heat insulating nanometer powder, 3-5 parts of modified potassium hexatitanate whisker pulp, 10-20 parts of an inorganic filler, 15-25 parts of silicone resin emulsion, 5-9parts of near-infrared reflective powder, 5-15 parts of silicone acrylic emulsion, 4-6 parts of cold pigment and 2-3 parts of an auxiliary agent. The coating includes the microcrystal heat insulatingnanometer powder and the near-infrared reflective powder, thus effectively improving heat insulation performance of the coating and reducing loss of energy of buildings. In addition, a preparation method of the coating is simple and suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of coatings, more specifically, it relates to a nano heat-insulating coating for buildings and a preparation method thereof. Background technique [0002] The whole society is paying attention to the issue of building energy saving and adopting corresponding technical means, aiming at saving energy and reducing consumption to promote environmental protection. At present, the commonly used wall reflective heat insulation technologies at home and abroad mainly include the following types: (1) Exterior wall ceramic tile facing reflective heat insulation, but the thickness of the tile facing and the adhesive mortar layer thicken the wall, and the tiles are bonded to the exterior wall. The space is easy to fall off, the construction waste increases, and there are safety hazards such as falling bricks, and the construction cost is high. (2) Vitrified microbeads combined with grid cloth for heat insulation and heat preserva...
