| 摘要 |
<p>The present invention shows the methods for preparing and synthesizing polymeric materials in emulsion or mini aqueous emulsion, as well as the method for using the same for encapsulating phase change materials, which result in products in emulsion with a high capacity of absorbing heat, with particle sizes ranging from 100 nm to 50,000 nm (50Um), with the purpose of being used in the development of coatings of high thermal and solar reflectivity. The preparation methods claimed in this invention present improved characteristics in terms of resistance against bleeding of the phase change compounds, control in the size particle and high capacity of heat absorption, presenting a high affinity by matrixes of different materials used in architectonic coatings, paints, specials, acrylic waterproofs or applied over surfaces of materials used in the construction industry, such as gypsum board, galvanized and asphaltic sheets, membranes of modified asphalt, amongst others.</p> |
