Embodiment 1
[0010] Put 90 parts by weight of zinc dialkyldithiophosphate into the reaction kettle, mix and heat 10 parts by weight of tetraethylenetriamine to 95°C, saponify for 90 minutes, then add 1 part by weight of tert-octanol, and then saponify for 60 minutes Minutes, cool down to 90°C, then add 5 parts by weight of benzotriazole, 1 part by weight of barium dinonyl naphthalene sulfonate, 3 parts by weight of dodecenylsuccinic acid, 7 parts by weight of chlorobromo Substituted alkyl phosphate flame retardant, stirred until completely dissolved, then cooled, filtered, and refined into compound additives.
Embodiment 2
[0012] Put 80 parts by weight of zinc dialkyldithiophosphate into the reaction kettle, mix and heat 5 parts by weight of tetraethylenetriamine to 90°C, saponify for 60 minutes, then add 0.5 parts by weight of tert-octanol, and then saponify for 60 minutes Minutes, cool down to 80°C, then add 3 parts by weight of benzotriazole, 0.5 parts by weight of barium dinonyl naphthalene sulfonate, 1 part by weight of dodecenylsuccinic acid, 5 parts by weight of chlorobromo Substituted alkyl phosphate flame retardant, stirred until completely dissolved, then cooled, filtered, and refined into compound additives.
Embodiment 3
[0014] Put 99 parts by weight of zinc dialkyldithiophosphate into the reaction kettle, mix and heat 15 parts by weight of tetraethylenetriamine to 120°C, saponify for 120 minutes, then add 1.5 parts by weight of tert-octanol, and then saponify for 120 minutes Minutes, cool down to 100°C, then add 8 parts by weight of benzotriazole, 1.5 parts by weight of barium dinonyl naphthalene sulfonate, 7 parts by weight of dodecenyl succinic acid, 10 parts by weight of chlorobromo Substituted alkyl phosphate flame retardant, stirred until completely dissolved, then cooled, filtered, and refined into compound additives.
[0015] The composite additives prepared in Examples 1-3 have the following superior properties: (1) Improve the high temperature resistance of the product: the dropping point is not less than 280°C (usually the dropping point of the product produced by a single additive is not greater than 250°C); (2) 1. Improve the anti-water performance of the product: the water loss o...
