Embodiment 1
[0013] Implementation example 1: the preparation technology of modified acrylic resin varnish is the following two steps:
[0014] In the first step, add 10g xylene, 1g n-butanol, 1.5g propylene oxide and 0.005g bimetallic salt to a 50mL three-necked flask equipped with a condenser tube, a thermometer and a stirrer, then stir and gradually heat to 100°C, keep warm for 60 minutes.
[0015] In the second step, the above reaction solution is transferred to a 250mL four-necked bottle equipped with a condenser, a thermometer, a stirrer and a dropping funnel, then stirred, and 32g of xylene and 8g of n-butanol are added while stirring, at 118 to 120 Under the temperature condition of ℃, add the mixed solution which has been mixed uniformly and contains 8.5g methyl methacrylate, 9.5g butyl acrylate, 5.5g acrylic acid and 0.2g initiator azobisisobutyronitrile dropwise at a uniform speed, and the dropping time is controlled at 60 minutes. After heat preservation for 120 minutes, cool...
Embodiment 2
[0016] Implementation example 2: the preparation technology of modified acrylic resin varnish is the following two steps:
[0017] In the first step, add 10 g of xylene, 1 g of n-butanol, 1 g of propylene oxide and 0.005 g of a double metal salt into a 50 mL three-necked flask equipped with a condenser, a thermometer and a stirrer. Then stir and gradually heat to 100°C and keep the temperature for 60 minutes.
[0018] In the second step, the above-mentioned reaction solution is transferred to a 250mL four-necked bottle equipped with a condenser, a thermometer, a stirrer and a dropping funnel, then stirred, and 30g of xylene and 8.5g of n-butanol are added while stirring. At a temperature of 120°C, add a mixed solution that has been mixed evenly and contains 9g methyl methacrylate, 9g butyl acrylate, 6g acrylic acid and 0.2g initiator azobisisobutyronitrile dropwise at a constant speed, and the dropping time is controlled for 60 minutes. Insulate for 120 minutes, cool to 35°C,...
Embodiment 3
[0019] Implementation example 3: the preparation technology of modified acrylic resin varnish is following two steps:
[0020] In the first step, add 12g xylene, 1g n-butanol, 1.5g propylene oxide and 0.004g bimetallic salt to a 50mL three-neck flask equipped with a condenser, a thermometer and a stirrer, then stir and gradually heat to 100°C, keep warm for 60 minutes.
[0021] In the second step, the above-mentioned reaction solution is transferred to a 250mL four-necked bottle equipped with a condenser, a thermometer, a stirrer and a dropping funnel, then stirred, and 31g of xylene and 7.5g of n-butanol are added while stirring. At a temperature of 120°C, add a uniformly mixed solution containing 8g of methyl methacrylate, 9g of butyl acrylate, 5g of acrylic acid and 0.2g of initiator azobisisobutyronitrile at a constant speed, and the dropping time is controlled at 60 minutes , keep warm for 120 minutes, cool to 35°C, then add 5.5g of copper oxide and 19.6g of oleic acid, ...
