Abstract

This invention relates to a method for preparing heat-insulating paint. The heat-insulating paint comprises: component A 75-90 wt.%, component B 5-20 wt.% and component C 5-20 wt.%. Component A comprises: emulsion 35-60 wt.%, emulsion paint auxiliary 5-30 wt.%, titanium dioxide 15-40 wt.% and water 20-45 wt.%. Component B is a surface-hydrophobic mineral material. Component C is heat-insulating silicate composite material. The method comprises modification treatment of the raw materials and preparation of the heat-insulating paint. The heat-insulating paint has such advantages as high IR reflectivity, good heat insulation, stable properties, low cost, convenient application and no environmental pollution. The method has such advantages as simple process and low cost, and is easy for mass production.

Description

technical field [0001] The invention relates to a paint technology, specifically a heat-insulating paint with high infrared reflectivity and low thermal conductivity and a preparation method thereof. The international patent classification number is proposed to be Int.Cl.C09D133 / 00 (2006.01). technical background [0002] With the soaring price of oil in the world, industrial energy conservation and building energy conservation have become the priority industries of various countries. A large number of statistical data prove that building energy consumption accounts for about 30-40% of the total energy consumption of the whole society, and this part of energy is mainly consumed by heating and air conditioning. If the airtightness of the building can be improved and the energy transfer to the walls, doors and windows can be reduced, the start-up frequency and time of the indoor air conditioner can be reduced while ensuring the same indoor temperature, and the heat energy requ...
