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...

Abstract

The invention discloses anti-doodling coating with scabridulous structure of photocatalysis cooperating with fluoro-siloxane resin modification, and belongs to wall surface anti-bonding coating. The coating is formed by mixing the following components in percentage by weight: 5 to 20 percent of silicon resin, 1 to 10 percent of cross-linking agent, 1 to 10 percent of fluororesin, 1 to 10 percent of curing agent, 0.1 to 1.3 percent of catalyst, 60 to 88 percent of organic solvent, 1 to 5 percent of inorganic powder addition agent and 2 to 10 percent of photocatalytic material; the modified organosilicon coating shows a protection effect on oil dirt, water and specific bonding objects, and the hardness is far more than that of a traditional organic coating; the coating has a photocatalysis self-cleaning effect, and can decompose multiple types of organic matters and organic dyestuff under a light-catalyzed reaction within a short time, so as to further decrease the bonding capability of sticky matters, enable the oil dirt to be more easily cleaned, and play a certain role in purifying air; moreover, the coating can work at extremely high temperature and also has excellent environmental suitability under saline, acid and humidity environment.

Description

technical field [0001] The invention relates to a wall anti-bonding coating, and more specifically, the invention mainly relates to an anti-graffiti coating with a micro-rough structure modified by photocatalysis and fluorosilicone resin. Background technique [0002] Graffiti damage has always been a major public hazard of modern human civilization. It stains objects with images or words that are harmful to the landscape, not only destroying the beauty of the city's appearance, but even destroying its structure. The most effective way to deal with graffiti is to use anti-graffiti paint, especially the most popular permanent anti-graffiti paint, which requires a hard and wear-resistant layer, graffiti difficult to stain on it, or easy to remove. Most of the existing coatings have some distance from the requirements of ideal anti-graffiti coatings. Among the existing anti-graffiti coatings, the main performance is determined by the resin used. In order to be widely used in...
