　　摘要 [目的]研发能代替传统保温被且性价比更高的新型日光温室保温被。[方法]朝外面料分别选用了淋膜无纺布、淋膜军用基布、珍珠棉（EPE）复合黑色PE编织布、无纺布复合黑色PE编织布，朝里面料选用了强力无纺布；芯材分别选用了喷胶棉、杂羊毛、珍珠棉（EPE）、化纤棉、微孔发泡材料，试制了5 种保温被，通过静态检测及室外试验，以市场主流保温被（牛津布+化纤棉）和（淋膜无纺布+化纤棉）为基准，对照分析了其保温性，且对面料测试了抗拉强度。[结果]静态检测报告表明，喷胶棉保温被和杂羊绒保温被的保温率分别为 840%和833%，而淋膜化纤棉保温被和牛津布化纤棉保温被的保温率分别为 75.0%和65.0%。室外试验表明，当室外温度最冷为-24.4 ℃时，喷胶棉保温被保温效果最好，室内温度达5.4 ℃；室外平均温度为-9.3 ℃时，室内平均温度为14.7 ℃；其次是杂羊绒保温被，室外温度为-24.4和-9.3 ℃时，室内温度分别达4.2和14.3 ℃；最差是牛津布化纤棉保温被和淋膜化纤棉保温被，室外温度为-24.4 ℃时，室内温度分别是2.8和3.6 ℃。[结论]喷胶棉保温被和杂羊毛保温被性能良好，可作为日光温室的新型高效保温材料推广。

　　Abstract [Objective] The aim was to research and develop a new type of thermal insulation in solar greenhouse which is costeffective and can replace traditional thermal insulation. [Method] Out of fabrics were chosen coated nonwoven， military base film， EPE composite black PE woven cloth， nonwoven fabric composite black PE woven cloth， inside fabrics were chosen nonwoven fabric； the core materials were chosen polyester wadding， miscellaneous wool， EPE， chemical fiber cotton， microporous foaming material. Through static test and outdoor test， with mainstream market thermal insulation（nylon oxford+chemical fiber cotton） and （coated nonwoven+chemical fiber cotton thermal insulation） as standard， the thermal insulation property was analyzed， and the tensile strength was tested.[Result] Static test report showed that heat preservation rate of polyester wadding and miscellaneous wool thermal insulation was 84.0% and 83.3% respectively， that of coated chemical fiber cotton and nylon oxfordthermal insulation was 75.0% and 65.0%. The outdoor experiment showed that， when minimum temperature outdoor was -24.4 ℃， heat preservation effect of polyester waddingthermal insulation was besst， temperature indoor was 5.4 ℃， average temperature outdoor was -9.3 ℃ and average temperature indoor weas 14.7 ℃； heat preservation effect of miscellaneous wool thermal insulation followed， when outdoor temperature was -24.4 and -9.3 ℃ ， indoor temperature was up to 4.2 and 14.3 ℃； nylon oxfordchemical fiber cotton and coated nonwovenchemical fiber cotton thermal insulation had poorest Effect， when outdoor temperature was -24.4 ℃ ， indoor temperature was 2.8 and 3.6 ℃. [Conclusion] Polyester wadding and miscellaneous wool thermal insulation has good performance， which can be promoted as a new type of thermal insulation materials in solar greenhouse.
