Embodiment 1
[0029] In this example, a kind of anti-graffiti coating with a photocatalytic synergistic modification of fluorosilicone resin and a microrough structure is prepared. The total weight is 50 kg. First, weigh 2.5 kg of silicone resin, 0.95 kg of crosslinking agent, and 0.5 kg of fluororesin. , 0.5 kg of curing agent, 0.05 kg of catalyst, 42 kg of organic solvent, 2.5 kg of inorganic powder additives, and 1 kg of photocatalytic material. The specific preparation method about coating is as follows:
[0030] Step 1: Add the organic solvent weighed according to the above amount into the reaction kettle, if necessary, add solid fillers into the organic volume, and stir the organic volume in the reaction kettle evenly;
[0031] Step 2: Add silicone resin, fluororesin, crosslinking agent, inorganic powder additives, catalyst, photocatalytic material, and curing agent to the reactor in sequence; then heat the reactor to above 50 degrees Celsius and control the speed at 500 Stir the mix...
Embodiment 2
[0034] In this embodiment, the total weight of the anti-graffiti coating with a photocatalytic synergistic fluorosilicone resin modified microrough structure is 120 kg. First, weigh 7.2 kg of silicone resin, 2.4 kg of crosslinking agent, and 7.2 kg of fluororesin. 12 kg of curing agent, 0.6 kg of catalyst, 84 kg of organic solvent, 1.8 kg of inorganic powder additive, and 4.8 kg of photocatalytic material. About the concrete preparation method of coating is substantially the same as embodiment 1, also operates according to the following steps:
[0035] Step 1: Add the organic solvent weighed according to the above amount into the reaction kettle, if necessary, add solid fillers into the organic volume, and stir the organic volume in the reaction kettle evenly;
[0036] Step 2: Add silicone resin, fluororesin, crosslinking agent, inorganic powder additives, catalyst, photocatalytic material, and curing agent in sequence in the reactor; then heat the reactor to above 50 degrees ...
Embodiment 3
[0039] In this example, the total weight of the anti-graffiti coating with a photocatalytic synergistic fluorosilicone resin modified microrough structure is 200 kg. First, weigh 32 kg of silicone resin, 2 kg of crosslinking agent, and 20 kg of fluororesin. 2 kg of curing agent, 2 kg of catalyst, 120 kg of organic solvent, 2 kg of inorganic powder additives, and 20 kg of photocatalytic material. About the concrete preparation method of coating is substantially the same as embodiment 1, also operates according to the following steps:
[0040] Step 1: Add the organic solvent weighed according to the above amount into the reaction kettle, if necessary, add solid fillers into the organic volume, and stir the organic volume in the reaction kettle evenly;
[0041] Step 2: Add silicone resin, fluororesin, crosslinking agent, inorganic powder additives, catalyst, photocatalytic material, and curing agent to the reactor in sequence; then heat the reactor to above 50 degrees Celsius and...
