Embodiment 1

[0025] Add 24% butyl methacrylate, 25% propylene glycol ethyl ether, 7.5% ketone, 3% acrylic acid, 8.5% ethylene glycol vinyl ether, 1% azo, 3% silicone acrylate into a closed reaction kettle, Vacuumize the system so that the pressure is -0.08~-0.1Mpa, add 28% chlorotrifluoroethylene (CTFE), and start stirring. After the addition, the temperature is raised to 70±5°C, and the temperature is reacted for 24 hours. After the reaction, the temperature is lowered to 60°C Recover the residual gas reactants, further lower the temperature to below 30°C and discharge the material, filter out the solid slag, drive away the bubbles to enhance the transparency of the product, and obtain the fluorocarbon resin. Its quality and performance indicators were tested as follows: viscosity of 45 seconds, solid content of 52.8%, acid value of 8.1 mgKOH / g, hydroxyl value of 50 mgKOH / g, and the content of benzene in the resin was zero. Use the paint containing the fluorocarbon resin of this example t...

Embodiment 2

[0027] Raw materials used: 22% methyl methacrylate, 25% propylene glycol methyl ether, 8% methyl ethyl ketone, 3% undecylenic acid, 8.5% ethylene glycol vinyl ether, 2% azo, 3.5% silicone acrylate, three Chlorofluoroethylene (CTFE) 28%, preparation method is the same as embodiment 1, and the quality performance index of the obtained fluorocarbon resin is as follows: viscosity 50 seconds, solid content 49%, acid value 7.6mgKOH / g, hydroxyl value 54.1mgKOH / g, The content of benzene substances in the resin is zero. Use the paint containing the fluorocarbon resin of this embodiment to make boards, and observe the hydrophobicity (surface energy) of the paint film: all the water drops fall off without water.

Embodiment 3

[0029] Raw materials used: vinyl acetate 20%, propylene glycol ethyl ether 20.5%, ketone 7.5%, undecylenic acid 3%, ethylene glycol vinyl ether 8.5%, azo 1.5%, silicone acrylate 4%, trifluorochlorine Ethylene (CTFE) 35%, preparation method is the same as embodiment 1, the quality performance index of the obtained fluorocarbon resin is as follows: viscosity 105 seconds, solid content 58%, acid value 7.8mgKOH / g, hydroxyl value 52mgKOH / g, benzene in resin Substance content is zero. Use the paint containing the fluorocarbon resin of this embodiment to make a board, and observe the hydrophobicity (surface energy) of the paint film: the water drops almost completely roll off, and do not stick to water.

[0030] Note: The board is made according to the national standard GB1727-92.

[0031] The viscosity is detected by the method of GB1724-89.

[0032] The solid content is detected by the method of GB6751-86.

Abstract

The present invention relates to ultra-low surface energy type fluorocarbon resin, which adopts chlorofluoroethylene, vinyl ester, vinyl acid, vinyl ether, initiator, and uses ether ester and ketone as solvent, and introduces organosilicone ester during polymerization production, Make the paint containing fluorocarbon resin have lower surface tension when forming a film, and further improve the self-cleaning property of the paint film.

Description

technical field [0001] The invention relates to a new chemical material, in particular to a low surface energy type fluorocarbon resin. Background technique [0002] As a surface decoration material, paint is mainly applied to the exterior walls of various buildings or the surface of other objects to protect and decorate. Due to long-term exposure to the outside, it is very easy to be polluted by dust and oil. In order to make the surface of the object easier to clean, it is urgent to develop a resin that has a lower surface tension when forming a film, and further improves the self-cleaning property of the paint film. Contents of the invention [0003] The low surface energy type fluorocarbon resin of the present invention introduces organosilicone ester during the polymerization of fluorocarbon resin, so that the fluorocarbon resin has lower surface tension when forming a film, and further improves the self-cleaning property of the paint film. [0004] Ultra-low surfac...
