Embodiment 1
[0031] Example 1: The preparation method of epoxy phosphate polyol is: place 100g triethyl phosphate, 0.2g tetrakis [β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol 2L four-neck bottle, and ensure the nitrogen environment in the four-neck bottle, then slowly raise the temperature to 80°C, add 50g of phosphorus pentoxide, keep the temperature at 85°C for 5 hours, and start adding 100g of trimethylol dropwise after obtaining a transparent solution Phosphine oxide, keep reflux and condense, continue to react for 3 hours, add 100g of epoxy resin DYD-127, 0.05g of stannous octoate, control the temperature at 85 ℃, and feed 15g of ethylene oxide until the acid value is less than 2mgKOH / g. Add 25g of epoxy resin DYD-127. After adsorption, filtration, distillation and other processes, the epoxy phosphate polyol with a phosphorus content of 15.63% was obtained, and no hydrolysis phenomenon was found during the storage period.
