Embodiment 1
[0016] Add 204g of aluminum isopropoxide and 65g of mineral oil weighed into a 1000ml four-necked flask with a condensing device, stir, heat up to 80°C, and drop 144g of 2-ethylhexanoic acid to carry out the displacement reaction. The reaction time is 1h, after the replacement reaction, heat up to 140°C for another 1h, add dropwise 150g of isopropanol with a water content of 12% to carry out the hydrolysis reaction, the hydrolysis reaction time is 5h, then add 65g of mineral oil to quickly cool down to 60°C, and filter 316 g of a clear light yellow oily liquid with an aluminum content of 8.5% was obtained.
[0017] Mix and stir resin, linseed oil, and kerosene in a ratio of 2:1:2 by weight and raise the temperature to 210°C, keep it warm for 15 minutes, and then naturally cool to 25°C to obtain resin oil with a viscosity of 35Pa.s. Take 100g of resin oil, heat up to 170°C, add 1.48 g of thickener prepared above, stir and disperse evenly, heat up to 175°C, keep it warm for 30 m...
Embodiment 2
[0019] Add 102g of measured aluminum isopropoxide and 50g of mineral oil into a 1000ml four-necked flask with a condenser, stir, heat up to 95°C, add 72g of 2-ethylhexanoic acid dropwise for displacement reaction, and the reaction time is 1h After the replacement reaction, heat up to 190°C, add 14.2g of crystalline aluminum sulfate with a water content of 45.7%, and perform a hydrolysis reaction. The hydrolysis reaction time is 3 hours, and then add 25g of mineral oil to quickly cool down to 60°C, and filter to obtain aluminum 165g of a clear light yellow oily liquid with a content of 8.18%.
[0020] Add 1.54g of the thickener prepared above to 100g of the resin oil prepared in "Example 1", raise the temperature to 170°C, stir and disperse evenly, then raise the temperature to 175°C, keep it warm for 30 minutes, and naturally cool down to 25°C , Test its viscosity, resin oil viscosity increased to 136Pa.s.
Embodiment 3
[0022] Add 204g of aluminum isopropoxide and 50g of 2-ethylhexanoic acid-1-methylethyl ester into a 1000ml four-necked flask with a condenser, stir, heat up to 85°C, and dropwise add 144g of 2-ethylhexanoate Carry out the replacement reaction of hexylhexanoic acid, the reaction time is 1.5h, after the replacement reaction is completed, heat up to 190°C, add 28g of crystalline aluminum sulfate with a water content of 45.7%, carry out the hydrolysis reaction for 4 hours, and add 2-ethylhexyl Acid-1-methyl ethyl ester 101g, cooled to 60°C and filtered to obtain 336 g of a clear light yellow oily liquid with an aluminum content of 8.03%.
[0023] Add 1.58 g of the above-prepared gel to 100 g of the resin oil prepared in "Example 1", raise the temperature to 175°C, stir and disperse evenly, keep warm for 30 minutes, then cool down naturally to 25°C, and test its viscosity , the resin oil viscosity increased to 121Pa.s.
