The invention relates to a simple method for preparation of a 180-degree peel strength sample during sealant 180-degree peel strength testing after air aging. By using a diluted sealant as a protective coating, the sealant 180-degree peel strength sample prepared according to HB5249-1993 'Room temperature vulcanization sealant 180-degree peel strength test method' will not be aged or brittle after air aging, and the rate of waste samples is reduced. 本发明说明了种热空气老化后测定密封剂180°剥离强度试验时，180°剥离强度试样制备的种简易方法。通过采用稀释的密封剂做为保护涂料，使得按照HB5249-1993《室温硫化密封剂180°剥离强度试验方法》制备的密封剂180°剥离强度试样在经热空气老化后不会老化发脆，使得废样比率降低。
