Abstract

The invention discloses a nanometer silicon heat-insulating coating and relates to the technical field of chemical industry. The nanometer silicon heat-insulating coating comprises the following components by weight percent: 25-35% of nanometer silicon resins, 15-20% of titanium dioxides, 10-15% of coarse whiting powder, 5-10% of phase-changing capsule particles, 5-10% of reflective heat-insulating powder, 3-5% of dodecanoic alcohol esters, 0.5-1% of polyacrylate, 0.3-1% of polyether modified siloxane, 0.3-1% of polycarboxylic sodium salt, 0.1-0.2% of 1,2-benzo isothiazolin-3-ketone, 0.8-1% of 2-(4-thiazolyl) benzimidazole and the balance of water. The nanometer silicon heat-insulating coating can solve the problem of inferior heat-insulating effect of the heat-insulating coating.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a heat-insulating coating and a production method thereof. Background technique [0002] At present, buildings are mainly constructed of concrete and brick walls, and this material absorbs light in a wide range, stores a large amount of heat, and dissipates heat slowly, which leads to a rapid rise in temperature inside the building and a long duration of high temperature. Especially in summer, when the atmospheric temperature is high and the intensity of solar radiation is high, the radiant heat absorbed from the roof and wall of the building will cause the indoor temperature to rise, the load of the air conditioner will increase, and more primary energy will be consumed. However, the heat-insulating coatings currently used mostly use the low thermal conductivity of the coating to reduce the indoor temperature by blocking the conduction of heat. The main problems o...
