摘　　要：以片状Al粉为金属颜料,加入ZnS、Na2SiO4、羧甲基纤维素钠和不同粘合剂制备低红外发射率涂料。将涂料涂覆在铝板上,比较含4种不同粘合剂涂层的发射率,研究粘合剂对涂层红外发射率的影响。将涂料涂覆在织物上,测量涂层的表观形态,分析工艺处方、织物种类等因素对织物涂层发射率的影响。油性聚氨酯粘合剂涂层的发射率最低,随着Al和ZnS含量的增加,织物涂层发射率逐渐降低,且不同织物基质上的涂层红外发射率不同。当使用油性聚氨酯为粘合剂,铝粉质量分数为35%～40%,ZnS质量分数为2%时,涤纶织物涂层发射率为0.69。Low infrared emissivity coatings were prepared from flaky Al powder, ZnS, adhesive, dispersant, and thickener. The coatings were applied to Al plate to investigate the emittance of coatings containing different adhesives. The coatings were applied to fabrics, and the microstructure and influence of preparation conditions on the infrared emittance of coating were analyzed. Oily polyurethane presented lower emittance than other adhesives. The emittance of coating on fabric reduced gradually with the increase of Al powder and ZnS. When oily polyurethane was used as adhesive,the content of Al was 35%-40%, and that of ZnS was 2%, polyester coating gave the radiant emissivity of 0. 69.
