[0018] Select 1kg of mature tung seeds, put them in the sun until the tung seeds crack, then remove the shells, pick out the tung seeds, wash them, and dry them in the sun until the water content of the tung seeds is 2%. The seeds are crushed in a grinder and passed through a 20-mesh sieve to obtain tung seed powder, which is placed in an oil press and pressed at 130°C, and then the oil is extracted to obtain crude tung oil, which is filtered and removed Impurities in tung oil were obtained from the filtrate, and the obtained filtrate was left to settle for 5 days at a temperature of 30°C, and the supernatant was taken to obtain refined tung oil; according to the mass ratio of 1:10, the attapulgite was soaked in The above obtained refined tung oil was soaked in 12h, after attapulgite was saturated, filtered to obtain saturated tung oil attapulgite, saturated tung oil attapulgite and deionized water were mixed in a mass ratio of 1:8, placed in an ultrasonic oscillator at 300r / ...

[0021] Select 1.5kg of mature tung seeds, expose them to the sun until the tung seeds crack, then remove the shells, pick out the tung seeds, wash them, and dry them until the water content of the tung seeds is 3%. The tung seed kernels are put into a pulverizer and crushed, and passed through a 23-mesh sieve to obtain tung seed powder, which is placed in an oil press, and the oil is pressed at 140 ° C, and then the oil is extracted to obtain crude tung oil, which is filtered and Remove the impurities in the tung oil to obtain the filtrate, and put the obtained filtrate at a temperature of 35°C for 7 days, and take the supernatant to obtain the refined tung oil; according to the mass ratio of 1:10, soak the attapulgite In the refined tung oil obtained above for 16 hours, after attapulgite is saturated, filter to obtain saturated tung oil attapulgite, mix saturated tung oil attapulgite with deionized water at a mass ratio of 1:8, place in an ultrasonic oscillator at 400r / min s...

[0024] Select 2kg of mature tung seeds, put them in the sun until the tung seeds crack, then remove the shells, pick out the tung seeds, wash them and dry them until the water content of the tung seeds is 5%. The seeds are crushed in a pulverizer and passed through a 25-mesh sieve to obtain tung seed powder, which is placed in an oil press and pressed at 160°C, and then the oil is extracted to obtain crude tung oil, which is filtered and removed Impurities in tung oil were obtained from the filtrate, and the obtained filtrate was left to settle for 10 days at a temperature of 40°C, and the supernatant was taken to obtain refined tung oil; according to the mass ratio of 1:10, the attapulgite was soaked in Put the above-mentioned refined tung oil for 24 hours, after the attapulgite is saturated, filter to obtain saturated tung oil attapulgite, mix saturated tung oil attapulgite with deionized water at a mass ratio of 1:8, place in an ultrasonic oscillator at 600r / Min speed stir...
