建筑用红外辐射降温涂料的研制

根据红外辐射致冷的基本原理，研究了红外辐射涂料的影响因素；通过微乳液聚合的方法描述了阴离子型Gemini表面活性剂在形成涂料用乳液中的功能，研究发现阴离子Gemini表面活性剂在微乳液聚合中是高效的乳化剂，可以提供典型的粒径控制，以及良好的乳液稳定性，只需1％左右就可以得到固含量45％左右的透明纳米级丙烯酸乳液；确定了辐射涂料的各种功能填料，并对填料进行处理，从而提高了填料反射和辐射功能，研制出了具有显著降温功能的辐射涂料。

Preparation of IR Radiant Refrigeration Coatings for Buildings

Based on the theory of infrared radiation refrigeration,this article is concentrated on the discussion of basic influencing factors for IR radiant coatings.Function of Gemini emulsifiers,an anionic emulsifiers,in emulsion for coatings,is illustrated by the process of micro-emulsion polymerization.It was found that Gemini emulsifiers are very effective in micro-emulsion polymerization,providing typical colloid particle size control,and excellent stability of the emulsion.With only about 1% content,high solid-content(about 45%) transparent copolymer latexes were attained.Various functional fillers for coatings were finalized,which were surface treated to improve its reflective and radiant ability,and the IR radiant coatings with remarkable refrigeration function was developed.
