Embodiment 1

[0064] 100 parts by mass of C6, 50 parts by mass of non-hydrophilic silica sol A, 2 parts by mass of S-60, 3 parts by mass of AEO-9, 2 parts by mass of AC-1810, 3 parts by mass of 1831 and 250 Parts by mass of water are added to the reactor, and the temperature is raised to 40°C to 45°C for pre-emulsification. Then homogenize under high pressure for 30 minutes, transfer the homogenized solution to the reaction kettle, and start stirring. Dissolve 0.5 parts by mass of initiator azobisisobutylamidine hydrochloride (AIBA) into 5 parts by mass of water to form a uniform solution, and add it into the reaction kettle. Then the temperature was raised to 70° C. to 75° C. for 5 hours to obtain the fluorosilicon hybrid polyacrylate dispersion of this example.

[0065] Examples 2-3 and Comparative Examples 1-3 adopt the same process as Example 1, and the specific formulations are shown in Table 1. That is to say, add the ingredients other than the initiator into the reactor, and raise ...

Embodiment 4

[0067] 80 parts by mass of C6, 40 parts by mass of non-hydrophilic silica sol A, 15 parts by mass of CA, 3 parts by mass of GA, 15 parts by mass of tripropylene glycol, 2 parts by mass of S-60, 3 parts by mass of Add AEO-9, 2 parts by mass of AC-1810, 3 parts by mass of 1831 and 238 parts by mass of water into the reactor, and heat up to 40-45°C for pre-emulsification. Then homogenize under high pressure for 30 minutes, transfer the homogenized solution to the reaction kettle, and start stirring. 0.5 parts by mass of the initiator AIBA was dissolved in 5 parts by mass of water to form a homogeneous solution, which was added to the reactor. Then the temperature was raised to 65° C. to start the timing reaction, and 2 parts by mass of vinyl chloride were introduced within 1 hour after the reaction started. The temperature was raised to 70-75° C. to continue the polymerization reaction for 5 hours to obtain the fluorosilicon hybrid polyacrylate dispersion liquid of the present i...

Embodiment 5

[0068] Example 5 and Comparative Example 4 adopt the same process as Example 4, and the specific formula is shown in Table 2. That is, first add the ingredients except the initiator and vinyl chloride into the reactor, and raise the temperature to 40-45°C for pre-emulsification. Then homogenize under high pressure for 30 minutes, transfer the homogenized solution to the reaction kettle, and start stirring. Mix the water and AIBA in the initiator to form a homogeneous solution and add it to the reactor, then raise the temperature to 65°C to start the timing reaction, and feed vinyl chloride within 1 hour after the reaction starts. The temperature was raised to 70-75° C. to continue the polymerization reaction for 5 hours, and the dispersion liquids of Example 5 and Comparative Example 4 were respectively obtained.

Abstract

Fluorine-silicon hybrid polyacrylate dispersion liquid comprises, by mass, 2-15 parts of surfactant, 215-263 parts of water and fluorine-silicon hybrid polyacrylate. Fluorine-silicon hybrid polyacrylate contains fluorine-containing alkyl acrylate monomer unit of C4-6 and is obtained by polymerizing 40-63.5 parts of hydrophobic silica sol and 85-100 parts of fluorine-containing alkyl acrylate monomer of C4-6 after co-emulsification. The fluorine-silicon hybrid polyacrylate dispersion liquid has good and lasting waterproof performance; testing shows that oilproof effect of textiles after the fluorine-silicon hybrid polyacrylate dispersion liquid acts on the textiles can reach Grade 6, and the dispersion liquid has good oilproof effect.

Description

technical field [0001] The invention relates to the technical field of waterproof treatment, in particular to a fluorosilicon hybridized polyacrylate dispersion. Background technique [0002] Acrylate polymers have certain waterproof performance, especially fluorine-containing acrylate polymers have better waterproof performance, and are often used in the technical field of waterproof treatment. It has been proved that C8 fluorine-containing acrylate has better waterproof effect and oil-proof performance than C6 and below fluorine-containing acrylate. but C 8 Due to the existence of perfluorooctanoic acid (Perfluorooctanoic Acid, PFOA) or perfluorooctane sulfonyl compound (perfluorooctane sulphonate, PFOS), facing the risk of being banned, it has been banned in developed countries such as Europe, America and Japan. Therefore, using C 6 and the following fluorine-containing acrylate replacement C 8 It has become a hot issue for scholars to study. Currently, using C 6 an...
