Embodiment 1
[0024] A kind of preparation method of anti-rat EVA foam shoe material, its steps are as follows:
[0025] (1) Air-dry after the borneol leaves are cleaned, cross 30 mesh sieves after pulverizing with a pulverizer, place in the extractor and add water and steam distill for 4 hours to obtain the mixture, the weight ratio of borneol leaves and water is 1:12, After extracting with ether, add anhydrous sodium sulfate for dehydration, remove the ether by rotary evaporation under reduced pressure, and obtain borneol leaf volatile oil;
[0026] (2) Add the borneol leaf volatile oil, CTAB, and deionized water obtained in step (1) into a constant temperature water bath, stir at 55°C and 1300rpm for 20 minutes to obtain a mixed solution, and add the mixed solution and ammonium persulfate to a four-necked flask and stirring at 400rpm, heated to 60°C and began to add MMA dropwise, heated to 70°C after dropwise addition, added AA dropwise and reacted for 4 hours, borneol leaf volatile oil,...
Embodiment 2
[0030] A kind of preparation method of anti-rat EVA foam shoe material, its steps are as follows:
[0031] (1) Air-dry after the borneol leaves are cleaned, cross 30 mesh sieves after pulverizing with a pulverizer, place in the extractor and add water and steam distill for 4 hours to obtain the mixture, the weight ratio of borneol leaves and water is 1:12, After extracting with ether, add anhydrous sodium sulfate for dehydration, remove the ether by rotary evaporation under reduced pressure, and obtain borneol leaf volatile oil;
[0032] (2) Add the borneol leaf volatile oil, CTAB, and deionized water obtained in step (1) into a constant temperature water bath, stir at 55°C and 1300rpm for 20 minutes to obtain a mixed solution, and add the mixed solution and ammonium persulfate to a four-necked flask and stirring at 400rpm, heated to 60°C and began to add MMA dropwise, heated to 70°C after dropwise addition, added AA dropwise and reacted for 4 hours, borneol leaf volatile oil,...
Embodiment 3
[0036] A kind of preparation method of anti-rat EVA foam shoe material, its steps are as follows:
[0037] (1) Air-dry after the borneol leaves are cleaned, cross 30 mesh sieves after pulverizing with a pulverizer, place in the extractor and add water and steam distill for 4 hours to obtain the mixture, the weight ratio of borneol leaves and water is 1:12, After extracting with ether, add anhydrous sodium sulfate for dehydration, remove the ether by rotary evaporation under reduced pressure, and obtain borneol leaf volatile oil;
[0038](2) Add the borneol leaf volatile oil, CTAB, and deionized water obtained in step (1) into a constant temperature water bath, stir at 55°C and 1300rpm for 20 minutes to obtain a mixed solution, and add the mixed solution and ammonium persulfate to a four-necked flask and stirring at 400rpm, heated to 60°C and began to add MMA dropwise, heated to 70°C after dropwise addition, added AA dropwise and reacted for 4 hours, borneol leaf volatile oil, ...
