[0035] A preparation method of a slip-resistant antifouling liquid, comprising the following steps:
[0036] S1, mix propylene, styrene and benzoyl peroxide, and add deionized water and catalyst A, stir and mix, and obtain product A after the reaction;
[0037] S2. After product A is cooled, add silicon fluoride modified polyurethane and catalyst B, stir and mix, heat and pressurize, and obtain product B after reaction.
[0038] S3. Add water-based resin to the product B in step S2, and stir while adding to prepare a slip-resistant antifouling liquid. The water-based resin here has a hydrophilic group and a lipophilic group. After adding, the product B can be mixed with water, and stirred while adding, until no water is separated. No water is separated. It means that there is no separation. layer phenomenon.
[0039] To further illustrate, in the step S1, the reaction conditions are: maintaining a pressure of 40-90 MPa and a temperature of 90-130 °C.
[0040] To further ill...
Embodiment A
[0073] The mass ratio between propylene, styrene and benzoyl peroxide is 1:1:1;
[0074] Step S1, adding benzoyl peroxide to propylene and styrene, adding deionized water accounting for 30% of the total mass, adding alkyl aluminum-titanium tetrachloride complex, stirring and mixing, at 70MPa, temperature 110°C reaction, product A is obtained after the reaction;
[0075] Step S2, after product A is cooled, add silicon fluoride modified polyurethane with different values of total mass (as shown in Table 1), add catalyst B, stir and mix, react at 300 MPa, and keep the temperature at 110 ° C, and obtain examples after the reaction Product B of A1-A9; the structural formula of fluorinated silicon modified polyurethane is as follows;
[0076]
[0077] where R 1 and R 2 for -ch 2 -CH 2 -;
[0078] Step S3: Add 10% of the total water-based resin to the product B in step S2, and stir while adding to prepare a slip-resistant antifouling liquid; the water-based resin is bisphe...
Embodiment B1
[0091] The mass ratio between propylene, styrene and benzoyl peroxide is 0.8:1.2:1;
[0092] Step S1, adding benzoyl peroxide to propylene and styrene, adding deionized water accounting for 20% of the total mass, adding alkyl aluminum-titanium tetrachloride complex, stirring and mixing, at 40MPa, temperature 90°C reaction, product A is obtained after the reaction;
[0093] Step S2, after product A is cooled, add silicon fluoride modified polyurethane accounting for 20% of the total mass, add alkyl aluminum-titanium tetrachloride complex, stir and mix, react at 350 MPa, and keep the temperature at 120 ° C, the reaction After obtaining the product B of different embodiments; the structural formula of fluorinated silicon modified polyurethane is as follows;
[0094]
[0095] where R 1 and R 2 for -ch 2 -CH 2 -;
[0096] Step S3, adding water-based resin accounting for 5% of the total amount to product B in step S2, and stirring while adding, to prepare an anti-slip antif...
