Example Embodiment
[0024] Example 1
[0025] 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, put them into a closed reactor, Vacuum the system to make the pressure -0.08~-0.1Mpa, add 28% chlorotrifluoroethylene (CTFE), and start stirring. After the addition, the temperature is raised to 70±5℃, and the reaction is kept at a constant temperature for 24 hours. After the reaction, the temperature is reduced to 60℃ The residual gas reactant is recovered, and the temperature is further lowered to below 30°C for discharging, the solid slag is filtered out, the bubbles are driven out, and the transparency of the product is enhanced to obtain fluorocarbon resin. The quality performance indicators are as follows: viscosity 45 seconds, solid content 52.8%, acid value 8.1mgKOH / g, hydroxyl value 50mgKOH / g, and the content of benzene in the resin is zero. Using a coating containing the fluorocarbon resin of thi...

[0026] Example 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 Fluorochloroethylene (CTFE) 28%, the preparation method is the same as in Example 1, the quality performance indicators of the obtained fluorocarbon resin are as follows: viscosity 50 seconds, solid content 49%, acid value 7.6mgKOH / g, hydroxyl value 54.1mgKOH / g, The content of benzene in the resin is zero. Using a coating containing the fluorocarbon resin of this embodiment to make a board, observe the hydrophobicity (surface energy) of the paint film: the water droplets all rolled off and did not stick to water.

[0028] Example 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%, trifluorochloride Ethylene (CTFE) 35%, the preparation method is the same as in Example 1. The quality performance indicators of the obtained fluorocarbon resin are as follows: viscosity 105 seconds, solid content 58%, acid value 7.8mgKOH / g, hydroxyl value 52mgKOH / g, benzene in the resin The content of similar substances is zero. Using a coating containing the fluorocarbon resin of this embodiment to make a board, observe the hydrophobicity (surface energy) of the paint film: almost all the water droplets roll off and do not touch water. Note: The board is made according to the national standard GB1727-92.
[0030] The viscosity is detected by the method of GB1724-89.
[0031] The solid content is detected by the method of GB6751-86.
