Embodiment 1
[0091] According to 100 mass parts of polypropylene surface (surface 1), maleic anhydride (5 mass parts) is dissolved in acetone (50 mass parts) to obtain maleic anhydride acetone solution; Sodium hydroxide (5 mass parts) is dissolved in de Aqueous sodium hydroxide solution was obtained in ionized water (50 parts by mass); the maleic anhydride acetone solution was added to the surface of the polypropylene under vacuum and fully contacted and mixed, and then the mixture was dried (80 ° C blast drying oven drying ). The mixture of dried maleic anhydride and polypropylene surface was microwaved (power 700W) for 5min under a nitrogen atmosphere; the microwaved product was soaked in deionized water for 10 minutes and replaced with deionized water for 3 times to ensure removal of untreated Participate in the maleic anhydride monomer of the grafting reaction, and then place it in an 80 ° C blast drying oven to dry the surface of the maleic anhydride grafted polypropylene; the sodium ...
Embodiment 2
[0094] According to 100 mass parts of polypropylene surface (with embodiment 1), maleic anhydride (5 mass parts) is dissolved in acetone (50 mass parts) to obtain maleic anhydride acetone solution; Sodium hydroxide (5 mass parts) is dissolved In deionized water (50 parts by mass), sodium hydroxide aqueous solution was obtained; the maleic anhydride acetone solution was added to the surface of the polypropylene under vacuum and fully contacted and mixed, and then the mixture was dried (80° C. oven dry). The mixture of dried maleic anhydride and polypropylene surface was microwaved (power 700W) for 5min under a nitrogen atmosphere; the microwaved product was soaked in deionized water for 10 minutes and replaced with deionized water for 3 times to ensure the removal of untreated The maleic anhydride monomer that participates in the grafting reaction is then placed in an 80°C blast oven to dry to obtain a dry maleic anhydride grafted polypropylene surface; an aqueous solution of s...
Embodiment 3
[0096] According to 100 mass parts of the polypropylene surface (same as Example 1), vinyl silicone oil (9 mass parts) is dissolved in ethanol (50 mass parts) to obtain vinyl silicone oil ethanol solution; sodium chloride (4 mass parts ) was dissolved in deionized water (50 parts by mass) to obtain an aqueous solution of sodium chloride; the vinyl silicone oil ethanol solution was added to the surface of the polypropylene under vacuum conditions to fully contact and mix, and then the mixture was dried (80 ° C blasting drying oven); the mixture of the dried vinyl silicone oil and the polypropylene surface is fully contacted and mixed with the sodium chloride aqueous solution, and then the mixture is dried (80°C blast drying oven); the dried mixture Microwave in a nitrogen atmosphere (power 1000W) for 3 minutes; soak the microwaved material in deionized water for 10 minutes and replace the deionized water for 3 times to ensure the removal of vinyl silicone oil monomers and sodium...
