Example Embodiment
[0040] Example 1
[0041] 1. Preparation of nylon 1012 salt: Weigh 1Kg of dodecanedioic acid, 4Kg of 99.5% ethanol, and mix to obtain an ethanol solution of dodecanediamine; weigh 0.96Kg of decane diamine, 1Kg of 99.9% ethanol, and mix to prepare Obtain the ethanol solution of decane diamine; heat the obtained ethanol solution of dodecane diamine to 35°C, and then add it dropwise to a stirred reactor containing the ethanol solution of decane diamine. The addition time is 20 minutes ; After standing for 15 minutes, put it in an ice water bath, collect the precipitated suspended matter, wash with ethanol to obtain nylon 1012 salt, and put it in a vacuum oven to dry for 48 hours;
