Embodiment 1

[0019] (1) 1.5 parts of auxiliary emulsifier sorbitan monooleate was added to 5 parts of plasticizer diisononyl phthalate, and then stirred in an oil bath pot at 50 °C for 20 min to obtain a dispersion;

[0020] (2) Subsequently, 5 parts of deionized water dissolved in 2 parts of the main emulsifier polyoxyethylene octylphenol ether-10 are slowly added to the dispersion obtained in step (1), and after the drop addition is completed, the homogenization continues to be homogenized at a speed of 800 rpm in the high-speed disperser for 20 min to form an oil-in-water emulsion;

[0021](3) 50 parts maleic anhydride grafted ethylene propylene monomer rubber, 20 parts high-crystalline polypropylene, 10 parts polyvinyl chloride, 10 parts polyethyleneimide dissolved in xylene and mixed evenly, under nitrogen conditions, 10 parts of highly reactive polybutene, 0.3 parts coupling agent (3-aminopropyl) triethoxysilane was added to the mixed solution, and then the solution was mechanically stir...

Embodiment 2

[0024] (1) 2.25 parts of auxiliary emulsifier dehydrated sorbitol monooleate was added to 7 parts of plasticizer diisononyl phthalate, and then stirred in an oil bath pot at 50 °C for 20 min to obtain dispersion;

[0025] (2) Subsequently, 10 parts of deionized water dissolved in 3 parts of the main emulsifier polyoxyethylene octylphenol ether-10 are slowly added dropwise to the resulting dispersion in step (1), and after the drip addition is completed, the homogenization continues to be homogenized at a speed of 800 rpm in the high-speed disperser for 20 min to form an oil-in-water emulsion;

[0026] (3) 40 parts maleic anhydride grafted ethylene propylene diene monomer rubber, 30 parts highly crystalline polypropylene, 15 parts polyvinyl chloride, 8 parts polyethyleneimide dissolved in xylene and mixed evenly, under nitrogen conditions, 15 parts of highly reactive polybutene, 0.5 parts coupling agent (3-aminopropyl) triethoxysilane was added to the mixed solution, and then the s...

Embodiment 3

[0029] (1) Add 0.75 parts of auxiliary emulsifier sorbitan monooleate to 6 parts of plasticizer diisononyl phthalate, and then stir in an oil bath pot at 50 °C for 20 min to obtain a dispersion;

[0030](2) Subsequently, 8 parts of deionized water dissolved in 1 part of the main emulsifier polyoxyethylene octylphenol ether-10 are slowly added dropwise to the dispersion obtained in step (1), and after the drop addition is completed, the homogenization continues to be homogenized at a speed of 800 rpm in the high-speed disperser for 20 min to form an oil-in-water emulsion;

[0031] (3) 60 parts maleic anhydride grafted ethylene propylene diene monomer rubber, 25 parts high-crystalline polypropylene, 10 parts polyvinyl chloride, 5 parts polyethyleneimide dissolved in xylene and mixed evenly, under nitrogen conditions, 6 parts of highly reactive polybutene, 0.4 parts coupling agent (3-aminopropyl) triethoxysilane was added to the mixed solution, and then the solution was mechanically ...
