Example Embodiment
[0021] Example 1
[0022] 12 parts of antioxidant 1010, 4 parts of antioxidant 168, 12 parts of zinc stearate, 8 parts of polyether modified silicone oil with hydroxyl value of 20-80mgKOH / g, diisooctyl phthalate or monophosphite Add 3 parts of benzenediisooctyl to the reaction kettle, slowly heat up to 50°C, keep stirring to keep all the solid components dissolved, and then add 4-hydroxy-2,2,6,6-tetramethylpiperidine-1- 15 parts of oxygen free radicals, continue to stir to form a uniform solution, then add 1.5 parts of methyl tin, 5 parts of sorbitan stearate, 4 parts of fatty alcohol polyoxyethylene ether, and 5 parts of polyoxyethylene sorbitan fatty acid ester Continue to stir for 10min, add the remaining amount of deionized water, and stir rapidly for 1h. Finally, it is emulsified by an emulsification pump to obtain product 1#.
Example Embodiment
[0023] Example 2
[0024] 12 parts of antioxidant 1010, 4 parts of antioxidant 264, 8 parts of zinc stearate, 5 parts of barium stearate, 10 parts of polyether modified silicone oil with hydroxyl value of 20~80mgKOH / g, diphthalic acid Add 4 parts of isooctyl ester or phenyldiisooctyl phosphite into the reaction kettle, slowly heat up to 80°C, keep stirring to make all the solid components dissolve, and then add 4-hydroxy-2,2,6,6-tetra 12 parts of methyl piperidine-1-oxyl radical, continue to stir to form a uniform solution, then add 2 parts of methyl tin, 3 parts of sorbitan stearate, 5 parts of fatty alcohol polyoxyethylene ether and polyoxyethylene sorbitan 3 parts of alcohol anhydride fatty acid ester were continuously stirred for 5 min, the remaining amount of deionized water was added, and then rapidly stirred for 0.5 h. Finally, it is emulsified by an emulsification pump to obtain product 2#.
Example Embodiment
[0025] Example 3
[0026] 15 parts of antioxidant 1010, 2 parts of antioxidant 168, 16 parts of calcium stearate, 4 parts of polyether modified silicone oil with hydroxyl value of 20-80mgKOH / g, diisooctyl phthalate or monophosphite Add 5 parts of benzenediisooctyl to the reaction kettle, slowly heat up to 80°C, keep stirring to keep all the solid components dissolved, and then add 4-hydroxy-2,2,6,6-tetramethylpiperidine-1- 18 parts of oxygen free radicals, continue to stir to form a uniform solution, then add 0.5 parts of methyl tin, 1 part of sorbitan stearate, 7 parts of fatty alcohol polyoxyethylene ether, and 1 part of polyoxyethylene sorbitan fatty acid ester Continue to stir for 10min, add the remaining amount of deionized water, and stir rapidly for 1h. Finally, it is emulsified by an emulsification pump to obtain product 3#.
