Abstract

The invention relates to a preparing method of modified heat insulating coating. Specific monomers and specific proportion are adopted, the surface of nanometer aluminum oxide is coated with polymer through the high-temperature polymerization technology, agglomeration of nanometer components in the coating is effectively avoided, and the dispersity and stability of the nanometer aluminum oxide in the coating are improved. In addition, due to the fact that the specific component proportion is adopted, a coating layer formed after the obtained coating is coated has various superior properties of good heat insulation performance, abrasive resistance, hardness, strength, adhesiveness and the like. The coating preparing method is simple, easy to implement and suitable for industrial production.

Description

technical field [0001] The invention relates to a preparation method of a modified heat-insulating paint. Background technique [0002] With the development of my country's construction industry, the importance of energy saving in houses has become increasingly prominent. Ordinary exterior wall coatings will absorb the infrared rays in sunlight and convert them into heat energy, causing the temperature of the coating to rise. raised. Theoretically speaking, as long as the heat radiation can be effectively reflected or blocked, the effect of heat insulation can be effectively achieved, such as the use of silicate materials. Classic wall thermal insulation materials include phenolic resin synthetic materials, polyurethane materials, glass fiber materials, aluminum silicate rock wool, mineral wool, rubber and plastic, cork, perlite, etc. These materials have the disadvantages of heavy weight, complicated construction and poor water resistance.
