所述的改性树木灰烬由以下步骤制得：先用10-15%盐酸浸泡树木灰烬3-4h，去离子水洗涤干净，再用10-12%氢氧化钠溶液浸泡3-4h，再用去离子水洗涤至中性，烘干，加入相当于树木灰烬重量2-3%的木质素磺酸钠、1-2%的二乙醇酰胺、2-3%的柠檬酸三丁酯、3-5%的纳米氧化铝，高速1200-1500r/min搅拌1-2h，烘干，粉碎研磨成超细粉末即可。
纳米白云石粉改性的氯丁橡胶胶黏剂的制备方法，包括以下步骤：
（1）将氯丁橡胶CR121 、二甲苯、4,4'-二苯基甲烷二异氰酸酯、聚异丁烯、3-氨丙基三甲氧基硅烷、聚四氢呋喃醚二醇、SG-2型PVC树脂、二茂铁、氯丁橡胶CR322、氯醇橡胶H4混合，在100-120℃下反应1-2h；
（2）将其它物料与反应物混合，搅拌30-40min，得到成品，包装即可。
本发明的有益效果：
本发明通过对树木灰烬进行改性，提高了其在在胶黏剂组分中的分散均匀性，从而可以明显改善制鞋用高性能用高性能胶黏剂的粘接强度和耐水性,并具有成本低,效果优良的特点。本发明纳米白云石粉改性的氯丁橡胶胶黏剂具有优良的耐热老化性，粘结强度高，耐水防潮，贮存稳定性好，环保性好，使用效果好且方便。
