Embodiment Construction
[0019] A specific implementation example is given below in detail as follows:
[0020] 1. According to the mass ratio, prepare the following raw materials:
[0021] , polyvinyl alcohol, white granular solid, 8 parts,
[0022] , VAE101 (ethylene-vinyl acetate copolymer emulsion), white emulsion, 60 parts,
[0023] , tert-butyl hydroperoxide, the mass concentration is 40% liquid, 0.012 parts,
[0024] , ferrous sulfate, line green powder, 0.010 parts,
[0025] , tri-n-butyl citrate, light yellow liquid, 9 parts;
[0026] 2. Put polyvinyl alcohol into the reaction kettle, add 15 parts of water, stir, and raise the temperature to 85°C until it is completely dissolved;
[0027] 3. Add VAE101 emulsion into the reaction kettle, stir for 15 minutes, and heat to 70°C;
[0028] 4. Add tert-butyl hydroperoxide and ferrous sulfate successively in the reaction kettle, stir, and react for 30 minutes;
[0029] 5. Heat up to 90°C, vacuumize to -0.03MPa, stir, and keep for 20 m...
