[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84.0%和83.3%,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。

摘  要：
[Objective] The aim was to research and develop a new type of thermal insulation in solar greenhouse which is cost-effective 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.
