Embodiment 1

[0030] A preparation method of fluorine-containing acrylate resin: add 60g of deionized water, 0.05g of nano silicon dioxide and 0.03g of sodium nitrite into a four-necked flask, stir at 200rpm to completely dissolve it, and wait until the temperature reaches After 50°C, add dropwise a uniform mixed solution consisting of 1g perfluoroalkylethyl methacrylate, 3g xylene and 0.38g azobisisobutyronitrile. There is a mixed solution of 0.12 g of azobisisobutyronitrile, 5 g of methyl methacrylate, and 0.2 g of isopropanol. Stir the reaction at a speed of 200 rpm for 2 h, then cool down to room temperature and discharge to obtain the product perfluoroalkylethyl methacrylate-methyl methacrylate copolymer.

[0031] The FTIR spectrogram of embodiment 1 product perfluoroalkyl ethyl methacrylate-methyl methacrylate copolymer, as figure 1 shown. 2960~2860cm -1 It is the C-H stretching vibration absorption peak of methyl and methylene, 1487cm -1and 1390cm -1 They are the shear vibration...

Embodiment 2

[0034] A preparation method of fluorine-containing acrylate resin: Add 70g of deionized water, 0.07g of magnesium hydroxide and 0.04g of sodium sulfite into a four-neck flask, stir at 200rpm to completely dissolve it, and wait until the temperature reaches 85°C , add dropwise a uniform mixed solution composed of 8g 2-(perfluorodecyl)ethyl methacrylate, 4.5g butyl acetate and 0.5g azobisisoheptanonitrile, and after the dropwise reaction is carried out for 15min, add additional drops A mixed solution of 0.2 g of azobisisoheptanonitrile, 20 g of methyl methacrylate, and 0.3 g of isopropanol was dissolved. Stir the reaction at a speed of 300 rpm for 5 h, then cool down to room temperature and discharge to obtain the product 2-(perfluorodecyl)ethyl methacrylate-methyl methacrylate copolymer.

Embodiment 3

[0036] A preparation method of fluorine-containing acrylate resin: add 75g of deionized water, 0.085g of polyvinyl alcohol and 0.05g of hydroquinone into a four-necked flask, stir at 200rpm to completely dissolve it, and wait until the temperature reaches 90 After ℃, add dropwise a uniform mixed solution composed of 16g ​​hexafluorobutyl acrylate, 6g 1,2-propylene glycol methyl ether and 1g dimethyl azobisisobutyrate. There is a mixed solution of 0.2 g of dimethyl azobisisobutyrate, 28 g of methyl methacrylate, and 0.4 g of n-hexanethiol. Stir the reaction at a speed of 400 rpm for 8 hours, then cool down to room temperature and discharge to obtain the product hexafluorobutyl acrylate-methyl methacrylate copolymer.

Abstract

The invention discloses a high-performance hydrophobic MMA (Methl Methacrylate) resin floor coating and a preparation method of the high-performance hydrophobic MMA resin floor coating and particularly relates to a high-performance hydrophobic floor coating which is compounded of acrylate resin containing particles synthesized by suspension polymerization and other resins. The high-performance hydrophobic MMA resin floor coating comprises a component A and a component B, wherein the component A is prepared in a way that an functional acrylate monomer, a plasticizer, a defoamer, a curing accelerator and sealing wax are added to an acrylic resin and methyl methacrylate containing homopolymer serving as a basic component and then dispersed; and the component B is an organic peroxide curing agent. The film of the floor coating has excellent mechanical property and good hydrophobic property and has high static-state water contact angle being above 115 degrees. In the construction process of the floor coating, no solvent volatilization problem is caused, the curing degree is high, no micromolecule is left after the floor coating is cured completely. So, the floor coating is a novel green product and has a broad development prospect.

Description

technical field [0001] The invention relates to an MMA resin paint, in particular to an MMA floor paint with good hydrophobicity prepared from a fluorine-containing acrylate resin and a preparation method thereof. technical background [0002] Methyl methacrylate (MMA) floor coatings use PMMA as the main resin base material, MMA and other reactive monomers as cross-linking agents, adding high melting point wax liquid, auxiliary supporting special powder, aggregate and additives and other materials And made of new polymer materials. Acrylic polymers have the characteristics of ultra-low temperature curing, fast curing, and no small molecule residues after complete curing. The prepared coating film has good aging resistance, light resistance, weather resistance, and excellent resistance to acids, alkalis, salts, and oils. Excellent durability, low price and simple synthesis process, etc., are widely used in factory workshops, large exhibition halls, indoor sports fields and o...
