[0013] The present invention provides a kind of preparation method based on the high temperature resistant chloroprene rubber modified by Jatropha fruit powder, comprising:
[0014] 1) The tung fruit powder, alginic acid, cyclodextrin, cetyltrimethylammonium bromide, ferrocene and water were subjected to hydrothermal reaction under airtight conditions, and then the filter cake was filtered to obtain the modified tung fruit powder ;
[0015] 2) Neoprene, polyvinyl butyral, polycarbonate, paraffin, zinc borate, vinyltriethoxysilane, linseed oil, N-cyclohexyl-N-phenyl-p-phenylenediamine, sulfur Dilauryl dipropionate, di-tert-butyl-p-cresol and peach gum are initially mixed to obtain a mixed product;
[0016] 3) The modified tung fruit powder and the kneaded product were mixed twice to prepare the high temperature resistant chloroprene rubber based on the modified tung fruit powder.
[0017] In step 1) of the above preparation method, the amount of each material can be selected ...
Embodiment 1
[0028] 1) Put tung fruit powder, alginic acid, cyclodextrin, cetyltrimethylammonium bromide, ferrocene and water at a weight ratio of 100:17:25:1.5:0.6:200 in a closed condition at 150°C The hydrothermal reaction was carried out for 4-6 hours, and then the filter cake was filtered to obtain the modified tung fruit powder;
[0029] 2) Neoprene, polyvinyl butyral (weight average molecular weight 3000), polycarbonate (weight average molecular weight 6000), paraffin, zinc borate, vinyl triethoxysilane, linseed oil, N -Cyclohexyl-N-phenyl-p-phenylenediamine, dilauryl thiodipropionate, di-tert-butyl-p-cresol and peach gum according to 100:50:28:49:15:26:37:5:10 : The weight ratio of 6:14 was preliminarily mixed at 190°C for 4 hours to obtain the mixed product;
[0030] 3) The kneaded product and the modified Jatropha fruit powder were mixed for a second time at 178°C for 1.5 h at a weight ratio of 100:18 to obtain high-temperature-resistant neoprene A1 modified based on Jatropha fr...
Embodiment 2
[0032] 1) Put Jatropha fruit powder, alginic acid, cyclodextrin, cetyltrimethylammonium bromide, ferrocene and water at a weight ratio of 100:14:20:0.8:0.4:150 in a closed condition at 140°C The hydrothermal reaction was carried out for 4 hours, and then the filter cake was taken by filtration to obtain the modified tung fruit powder;
[0033] 2) Neoprene, polyvinyl butyral (weight average molecular weight 2000), polycarbonate (weight average molecular weight 4000), paraffin, zinc borate, vinyl triethoxysilane, linseed oil, N -Cyclohexyl-N-phenyl-p-phenylenediamine, dilauryl thiodipropionate, di-tert-butyl-p-cresol and peach gum according to 100:48:23:40:11:20:30:4:7 : Preliminary kneading at 185°C for 3 hours at a weight ratio of 2:10 to obtain a kneaded product;
[0034] 3) The kneaded product and the modified tung fruit powder were mixed for a second time at 175°C for 1 h at a weight ratio of 100:16 to obtain high-temperature-resistant chloroprene rubber A2 modified based ...
