摘要
目的:制备一次性理疗保健用自发热材料。方法:用脲、硫脲、聚乙二醇(PEG)制备了Polymer in Salt型聚合物固体电解质(SPE),将该SPE与还原铁粉、活性炭物理共混制备自发热材料。结果:自发热材料形态为固态,接触空气后释热,不接触空气时处于休眠状态,控制其与空气的接触量可实现热量的控制释放,释热效果良好。结论:SPE与金属粉末、活性炭物理共混可以制备性能优良的固态自发热材料,该材料可用于橡胶硬膏剂或黑膏药的发热裱褙材料、人体热敷材料等一次性医用制品。
Objective To prepare a kind of one-off self-heating material for physical therapy and health care. Methods Polymer in salt sohd electrolyte （SPE）was prepared with urea, thiourea and polyethelene glycol （PEG）. The SPE was chosen to prepare a self-heating material through mixing with reduced iron powder and activated carbon powder. Results The self-heating material was in solid state and performed satisfactory. It released heat when contacted with air and was in dormancy when isolated from air. Conclusion SPE can be used for solid self-heating material through mixing with metal powder and activated carbon powder. The self-heating material can be used for mount of ointment and for other heat-wanted one-off medical use.[Chinese Medical Equipment Journal, 2008,29 （4） ： 61,63]
