Description

Technical Field

[0001] This application relates to the technical field of coatings, and more specifically, it relates to a high waterproof and high weather-resistant fluorocarbon paint and a preparation method thereof. Background Technique

[0002] With the development of modern architecture and industry, the performance requirements for coatings are getting higher and higher. In the fields of building exteriors, bridges, and metal structures, when exposed to harsh environments such as ultraviolet rays and acid rain for a long time, problems such as powdering, fading, and peeling are likely to occur, resulting in a shortened service life. For example, building exterior wall coatings need to meet the requirement of more than 15 years of anti-aging performance. This requires that the coating needs to have good waterproof and weather-resistant properties to protect the coated object from moisture erosion.

[0003] Existing fluorocarbon paints mostly rely on traditional flame-retardant systems containing halogens, etc. Toxic gases are easily released during combustion, and the flame-retardant efficiency is limited. Or mainly rely on the C-F bond of fluorocarbon resin to achieve the hydrophobic effect, but it is easily eroded by water and chemical substances during long-term use, resulting in the failure of the waterproof layer. Therefore, existing fluorocarbon paints mostly focus on single performance and are difficult to meet the needs of multiple scenarios. For example, a Chinese invention patent application with the publication number CN105885660A, a flame-retardant and environmentally friendly paint and a preparation method thereof. This paint has flame-retardant properties and is used for plastic coating, which can slow down the damage of plastic during combustion, thus achieving the effect of plastic flame retardation; however, its waterproof effect has not been improved. Summary of the Invention

[0004] To solve the problems raised in the background technique, this application provides a high waterproof and high weather-resistant fluorocarbon paint and a preparation method thereof.

[0005] This application provides a high waterproof and high weather-resistant fluorocarbon paint and a preparation method thereof, adopting the following technical scheme:

[0006] A high waterproof and high weather-resistant fluorocarbon paint, including the following weight components: 45 - 65 parts by weight of fluorocarbon resin, 8 - 10 parts by weight of butyl acetate, 2 - 4 parts by weight of phosphorus-containing polymer, 1 - 2 parts by weight of cashew phenol glycidyl ether, 1 - 3 parts by weight of talc powder, 0.3 - 0.4 parts by weight of polysiloxane defoamer, 1 - 2 parts by weight of propylene glycol, 0.3 - 0.4 parts by weight of polyacrylate leveling agent, 0.4 - 0.6 parts by weight of bentonite.

[0007] Preferably, the preparation method of the phosphorus-containing polymer is:

[0008] S1. Add DOPO to dichloromethane, then place it in a magnetic stirrer with an ice-water mixture for stirring. After the temperature reaches 1 - 2 °C, add 2-hydroxyethyl methacrylate and triethylamine to it, mix well, maintain the temperature at 1 - 2 °C, continue to add carbon tetrachloride to it, control the temperature at 5 - 10 °C, continue the reaction for 1.5 - 2 h, then take it out and stir the reaction at room temperature. After the reaction is completed, place it in a separatory funnel, add 2 mol / L hydrochloric acid to remove the excess triethylamine, then wash it several times with distilled water to remove the triethylamine salt crystals, and dry it with anhydrous magnesium sulfate to obtain Intermediate 1;

[0009] S2. Add 3-hydroxy-1-adamantyl methacrylate and benzoyl chloride to N,N-dimethylformamide solvent, stir and mix, react at 90 - 110 °C, and after completion, perform vacuum distillation, wash and dry to obtain modified adamantane;

[0010] S3. Under an inert atmosphere, add the modified adamantane, Intermediate 1, methyl acrylate, and acrylamide to a reactor equipped with N,N-dimethylformamide solvent, stir evenly, continue to add azobisisobutyronitrile to it, raise the temperature and react for 12 - 16 h. After completion, perform vacuum distillation, filter and wash to obtain a phosphorus-containing polymer.

[0011] During the above reaction process, the phosphorus-hydrogen bond of DOPO undergoes a dehydration condensation reaction with 2-hydroxyethyl methacrylate, introducing an alkenyl group; the hydroxyl group in 3-hydroxy-1-adamantyl methacrylate undergoes an esterification reaction with the acyl chloride in benzoyl chloride, introducing an alkenyl group, thus obtaining modified adamantane; the modified adamantane, Intermediate 1, methyl acrylate, and acrylamide undergo a polymerization reaction to obtain a phosphorus-containing polymer.

[0012] Preferably, in S1, the dosage ratio of DOPO, dichloromethane, 2-hydroxyethyl methacrylate, triethylamine, and carbon tetrachloride is 17.21 - 17.29 g : 50 - 55 mL: 12.4 - 12.8 g: 9.5 - 9.7 g: 14.71 - 14.76 g.

[0013] Preferably, in S1, the time for stirring the reaction at room temperature is 22 - 24 h.

[0014] Preferably, in S2, the dosage ratio of N,N-dimethylformamide, 3-hydroxy-1-adamantyl methacrylate, and benzoyl chloride is 30 - 45 mL: 2.33 - 2.42 g: 2.26 - 2.37 g.

[0015] Preferably, in S2, the reaction time is 4 - 7 h.

[0016] Preferably, in S3, the reaction temperature is 95 - 102 °C.

[0017] Preferably, the dosage ratio of the modified adamantane, intermediate 1, methyl acrylate, acrylamide, N,N-dimethylformamide, and azobisisobutyronitrile in S3 is 1.2 - 1.3 g : 0.85 - 1.14 g : 0.6 - 0.8 g : 1 - 1.2 g : 30 - 40 mL : 0.01 - 0.02 g.

[0018] Preferably, the preparation method of the high-waterproof and high-weather-resistant fluorocarbon paint is as follows: Add fluorocarbon resin, butyl acetate, phosphorus-containing polymer, cardanol glycidyl ether, talcum powder, polysiloxane defoamer, propylene glycol, polyacrylate leveling agent, and bentonite into a stirrer, mix and stir. After stirring for 15 - 20 min, let it stand at room temperature for 3 - 4 h to obtain the high-waterproof and high-weather-resistant fluorocarbon paint.

[0019] In summary, the present application has the following beneficial effects:

[0020] 1. In the present application, fluorocarbon resin, butyl acetate, phosphorus-containing polymer, cardanol glycidyl ether, talcum powder, polysiloxane defoamer, propylene glycol, polyacrylate leveling agent, and bentonite are added into a stirrer, mixed and stirred. After stirring for 15 - 20 min, let it stand at room temperature for 3 - 4 h to obtain the high-waterproof and high-weather-resistant fluorocarbon paint.

[0021] 2. The phosphorus element in the phosphorus-containing polymer has a good flame retardant effect. When burning, the phosphorus element can generate polyphosphoric acid and metaphosphoric acid with strong dehydrating properties. Since polyphosphoric acid and metaphosphoric acid are not easily volatile, they can form a dense protective layer on the surface of the coating, thus achieving a flame retardant effect. The benzene ring group and adamantyl group in the phosphorus-containing polymer both have good waterproof effects and hydrophobic effects. Applying them in the paint can improve its waterproof property. During the stirring process, the hydroxyl group in the phosphorus-containing polymer and the epoxy group in cardanol glycidyl ether undergo ring-opening reactions, generating crosslinks with each other to form a crosslinked network. Moreover, the long chain in cardanol will be tightly wound with the fluorocarbon resin, making them more dense with each other, further improving its waterproof effect. Detailed Embodiments
