Abstract
高爆速耐热混合炸药是一种有机组合物。本发明解决的问题是获得一种能经受180℃～200℃高温达48小时，并具有较高的爆速的耐热炸药。该炸药是一种高爆速耐热混合炸药，它以奥克托今炸药为主体，加入一定量的高熔点炸药，外加3～4%的有机氟胶粘剂作为粘结剂，其爆速高达8000/秒左右，承受180℃～200℃高温48小时后爆轰性能不变。可用于深井石油射孔弹及导爆索，雷管的装药及其他方面，特别是能满足无电缆射孔技术的需要。
Description
本发明是一种有机组合物。
当今世界各国都用爆炸技术即射孔弹来开采石油。随着钻井深度增加，地温提高，所用炸药承受的温度提高。射孔技术的发展，又使得所用炸药承受高温的时间大大增长。我国在采用常规射孔技术时，要求炸药能经受住2小时的高温，由奥尔洛娃所著“奥克托今”（1975年）一书可知苏联提出的要求是能经受住6小时的高温。我国目前正在发展的无电缆射孔技术，要求炸药能经受住长达48小时的高温。这一要求是更加苛刻了，因为经受高温的时间愈长，所能承受住的温度就愈低。此外，为了得到更高的射孔深度，提高采油效率，所用炸药应具有尽可能高的爆速。
目前世界各国使用和研制的耐热炸药中，以奥克托今（HMX）为基的混合炸药，其爆速较高，可达8000米/秒以上。但耐热性相对较低，“奥克托今”一书提供的数据为：当受热时间为6小时时，这类炸药的耐热极限为200℃。我国最新产品所达到的指标为2小时220℃，根据动力学参数推算的结果为：受热48小时时，这类炸药的耐热极限为160℃。而一些高熔点炸药（熔点在300℃以上），如六硝基芪，塔科特（TacooT），2，6-双（苦氨基）-3，5-二硝基吡啶（PYX）等，其耐热性相当好，但爆速较低，据文献E.E.Kilmer;J.Spacecraft and Rockets 5.1216（1968），U.S.P.3089796，3131102，3140212和E.P.104717，U.S.P.3678061等提供的数据，它们的爆速仅6000多米/秒至7000多米/秒，最大也不到7500米/秒，实际使用中所能达到的值还要小一些。
本发明的目的是得到一种爆速较高，耐热性又符合一定深度油井的无电缆射孔技术要求的耐热炸药，其组分可根据使用温度进行调节。
本发明是以奥克托今（HMX）炸药作为主体，其量为70-90%（重量），加入10-30%与奥克托今相容性好的、熔点比奥克托今更高的炸药如六硝基芪或苦味酸钾或2，4，6，8-四硝基吖叮酮等（其含量随使用温度升高而增加）之后，再以上述混合炸药为基准，另外加入3-4%的有机氟胶粘剂，按常规高分子粘结炸药的制备方法制备而成。
实施例：80%奥克托今加20%2，4，6，8-四硝基吖叮酮，另外再加3-4%有机氟胶粘剂（FS-320胶）制成造型粉后，压成药柱，当压制密度为1.74克/厘米3时，实测爆速为8000米/秒左右。用6.5克本品装于8429型石油射孔弹内，实验对比加热48小时后与未加热的射孔深度，结果职下表：
上述结果说明本发明的产品经受48小时180℃的高温后，爆炸性能保持不变。
本发明的耐热性优于奥克托今炸药，爆速高于前述的高熔点类炸药，经受180℃-200℃的高温48小时，爆炸性能保持不变。且其组分可根据使用温度进行调节。可用于深井石油射孔弹及导爆索、雷管的装药及其他方面，特别是能满足无电缆射孔技术的需要。
