Embodiment 1
[0025] A kind of preparation method of modified starch, described method is,
[0026] a, calcium carbonate with a particle size of nano-scale is used as an inorganic powder, and it is added to a high-speed mixer together with a silane coupling agent and stirred and mixed under heating conditions. The ratio is 97% of calcium carbonate, silane coupling agent Mixing agent 3%, mixed for 15 minutes at 100°C, then taken out and cooled to obtain mixed powder;
[0027] b. After drying the potato starch, grind the superfine powder until the particle size exceeds 300 mesh sieve; mix the mixed powder obtained in step a with the ground starch, methacrylic acid, polyol, styrene / ethylene / propylene / Styrene copolymer, dilauroyl peroxide, and silane coupling agent are mixed according to the proportion, and the proportion is calculated by weight percentage: starch 89.8%, methacrylic acid 0.5%, polyol 3%, styrene / ethylene / Propylene / styrene copolymer 3%, dilauroyl peroxide 0.5%, silane coupli...
Embodiment 2
[0030] A kind of preparation method of modified starch, described method is,
[0031] a. Titanium dioxide with a particle size of nano-scale is used as an inorganic powder, and it is added to a high-speed mixer together with a titanate coupling agent and stirred and mixed under heating conditions. The ratio is: 98% titanium dioxide, titanic acid 2% ester coupling agent, mix at 90°C for 20 minutes, then take out and cool to obtain mixed powder;
[0032] b. After drying the tapioca starch, grind the superfine powder until the particle size exceeds 400 mesh sieve; mix the mixed powder obtained in step a with the ground starch, dodecenylsuccinic anhydride, and dibutyl phthalate , ethylene-methacrylate copolymer, bis-2-phenoxyethyl peroxydicarbonate, and titanate coupling agent are mixed according to the proportion, and the proportion is calculated by weight percentage: starch 65%, dodecene 3% succinic anhydride, 8% dibutyl phthalate, 8% ethylene-methacrylate copolymer, 3% bis-2-p...
Embodiment 3
[0035] A kind of preparation method of modified starch, described method is,
[0036] a, the nano-sized montmorillonite is used as an inorganic powder, and is added to a high-speed mixer together with a silane coupling agent and a titanate coupling agent, and stirred and mixed under heating conditions, and the proportion is as follows: , 99% of montmorillonite, 0.5% of silane coupling agent, and 0.5% of titanate coupling agent were mixed at 80°C for 20 minutes, then taken out and cooled to obtain a mixed powder;
[0037] b, after drying the wheat starch, grind the superfine powder until the particle size exceeds 600 mesh sieve; combine the mixed powder obtained in step a with the ground starch, maleic anhydride acrylic acid copolymer, glycerin, sorbitol, lactic acid, and Oxidized bis(2-ethyl)hexyl dicarbonate and silane coupling agent are mixed according to the proportion, and the proportion is calculated by weight percentage, starch 66.5%, maleic anhydride acrylic acid copoly...
