METHOD FOR ENCAPSULATING PHASE TRANSITIONAL PARAFFIN COMPOUNDS USING MELAMINE-FORMALDEHYDE AND MICROCAPSULE RESULTING THEREFROM |
摘要 |
<p>A process for the microencapsulation of phase transitional paraffin compounds is described. Polypropylene glycols with the average molecule weight over 400 were used as the surface tension modifiers for emulsifying the paraffin compounds. Polyisocyanates capable of being dissolved in the phase change materials were employed to promote the deposition of melamine, partially methylolated melamine and the precondensate of melamine-formaldehyde onto the hydrophobic droplets for the microencapsulation. The prepared emulsion of microencapsulated phase change materials was successfully coated on textile fabrics and the coated products showed improved thermal regulation function.</p> |
