Description
Technical Field
The invention relates to the field of coatings, and particularly relates to an anti-graffiti coating composition.
Background
In recent years, damage caused by graffiti has received increasing attention. In public places, various sprayed doodles and randomly posted small advertisements can be seen anywhere in public transport vehicles such as subways, trains and buses or public facilities such as bus shelters, telegraph poles and outer walls, so that the appearance of a city is influenced, and a building structure is damaged to a certain extent. Currently, the cost of removing graffiti in public places is enormous in countries, but it is impractical to reduce the amount of graffiti. On the other hand, in the indoor home, children can randomly paint and scrabble on the wall surface of the home due to the nature, and the erosion of the marking pen and the oil pen is usually larger than that of the painted pen, so that great trouble is caused to parents. Therefore, there is a need to develop coatings with anti-graffiti properties that aim to remove graffiti in a simple way, e.g. only with water, even without water, with a paper towel/dry cloth.
At present, the anti-graffiti coatings commonly used on the market mainly comprise fluororesin coatings, water-based cross-linked fluorine-containing compound coatings, polyurethane coatings and organic silicon modified coatings. The organic silicon modified coating is an anti-graffiti coating obtained by modifying a common coating by using organic silicon as an additive/auxiliary agent. Polysiloxane has excellent hydrophobicity, oleophobicity and lubricity, and can obviously reduce the surface energy of a coating film when applied to the coating, and researches find that the surface with low surface energy can effectively prevent graffiti adhesion and pollution, so that some researches are carried out on organosilicon modified anti-graffiti coatings in the prior art.
CN101585995A discloses an organosilicon modified bi-component anti-graffiti coating based on acrylic resin, which comprises a component A and a component B, wherein the component A comprises hydroxy acrylic resin, fluorocarbon resin, modified polydimethylsiloxane resin, polyacrylate modified organosilicon resin, smooth flowing agent, flatting agent, defoaming agent, drier, dibutyltin dilaurate, butyl acetate and dimethylbenzene; the component B comprises hexamethyl diisocyanate biuret, butyl acetate and ethylene glycol ethyl ether acetate. The coating film formed by the organic silicon modified coating can resist graffiti and paste, and the oily pen on the surface of the coating film and the sprayed graffiti can be wiped off by lint-free cotton cloth dipped with a citrus-based detergent, but the coating contains organic solvents and VOC.
US9328259B discloses an elastomeric silicone emulsion anti-graffiti modifier for PVC coatings and example 2 discloses that the modifier comprises a silicon-based capped polyether, an alkoxy group containing polysiloxane, an emulsifier and water. The PVC coating modified with the elastomeric silicone emulsion has excellent tensile strength and elongation, and although US9328259B also qualitatively describes that the modified PVC coating has anti-graffiti properties, it is not characterized. In addition, after the modified PVC coating is formed into a film, the surface of the coating is easy to be sticky, easy to be dusty and poor in adhesion resistance.
EP1083195A discloses an alkoxylated resin-polymer organosiloxane network useful as an anti-graffiti coating additive and example 11 discloses the following process: i) mixed bis-hydroxy-terminated polydimethylsiloxane (kinematic viscosity at 25 ℃ C. of 75 mm)2/s)、74wt%Methyl radicalXylene solution of MQ silicone resin, 25 wt% sodium methoxide in methanol; ii) adding methyltrimethoxysilane, hexamethyldisiloxane and aminosilane to carry out reaction; iii) adding a neutralizing agent to the reaction product. Although EP1083195A discloses that the organosiloxane network has excellent tensile strength and generally describes its use as an additive for anti-graffiti coatings, its anti-graffiti properties have not been investigated.
In the anti-doodling paint, the organosilicon is used as an additive, and in order to achieve an ideal anti-doodling effect, the compatibility of the organosilicon and a paint system, whether the organosilicon can be quickly mixed into the paint system, whether negative effects are generated on other performances of the paint, whether good long-term anti-sticking property and dust resistance of a coating film can be endowed and the like need to be considered, and if the problems cannot be solved properly, the anti-doodling and anti-sticking effect of the paint can be directly influenced. In order to avoid possible negative effects of the organosilicon additive and the coating system, the subsequent prior art also carries out certain research on the anti-graffiti coating taking organosilicon as the main body.
US8772407B discloses a one-component silicone based coating composition and comparative example 6 discloses a coating composition consisting of a hydroxy silicone resin Dow Corning 805, an alkoxy silicone resin Dow Corning 3074, an aminosilane and an organotin catalyst, wherein Dow Corning 805 is a hydroxy silicone resin diluted with xylene with a resin content of 50 wt% and a VOC content of 503 g/L. Although the background section of US8772407B discloses that polysiloxane coatings have graffiti resistance, it does not characterize the graffiti resistance of the comparative example 6 coating composition.
US8277555B discloses a one-component, silicone-based anti-graffiti coating composition, and examples 1-3 disclose that the composition comprises a) a mixture of a methyl silicone resin containing 31 wt% alkoxy groups and a methyl phenyl silicone resin containing 18 wt% alkoxy groups, b) an organotin catalyst, c) an aminosilane, and d) a glycidyl group containing compound. The coating composition has a graffiti-resistant effect on marking pens, oil-based pens and spray paints, but the graffiti removal operation is inconvenient and requires the use of solvents for removal.
WO2011120735A discloses a one-component silicone-based anti-graffiti coating composition and example 3 discloses that the composition comprises a 15 wt% aqueous solution of an oligomeric amino fluoroalkyl organosiloxane, an ethylene oxide-propylene oxide block copolymer, and water. The composition has improved film-forming properties, has an anti-graffiti effect on markers and spray paints after film formation on a substrate, but is inconvenient in graffiti removal operation, requires a 10-minute action of N-methylpyrrolidone (NMP) on graffiti, is washed with water and lightly brushed on the surface, and is highly likely to abrade the coating film when removing graffiti.

In a first aspect the present invention provides a coating composition comprising the following ingredients:
alkoxy silicon resin, hydroxyl silicone oil, aminosilane and a catalyst.
The coating composition may be a one-component system, i.e. the alkoxysilane resin, the hydroxy silicone oil, the aminosilane and the catalyst are present in one package. In order to avoid the chemical reaction of the alkoxy silicon resin and the hydroxyl silicone oil in the storage process to influence the service performance of the coating, a single-component system is not suitable to contain water. By "free of water" is meant that the amount of water in the system is less than 0.1 wt%, even less than 0.01 wt%, and even less than 0.001 wt%, based on the total weight of the coating composition. When the single component is cured to form a film, alkoxy in the system reacts with hydroxyl under the action of a catalyst, and the alkoxy can be hydrolyzed and condensed with water in the air under the action of the catalyst to be cured. To facilitate curing of the coating composition, the molar amount of alkoxy groups in the component is significantly greater than the molar amount of hydroxyl groups.

When the two components are mixed, alkoxy in one component reacts with hydroxyl in the other component under the action of a catalyst, and the mixture is cured to form a film; the alkoxy in one component can be hydrolyzed and condensed with water in the air under the action of a catalyst to be solidified. To facilitate curing of the coating composition, the molar amount of alkoxy groups in one component is significantly greater than the molar amount of hydroxyl groups in the other component. In the present invention, for storage of the coating composition, a two-component system is preferred. The two-component system of the present invention may contain a small amount of water or be substantially free of water, for example, the amount of water in the hydroxyl-containing silicone oil component is less than 2% by weight and the amount of water in the alkoxy-containing silicone resin component is less than 0.1% by weight, based on the total weight of the coating composition.
Further, in order to improve the flexibility of the coating film and facilitate the application of the coating composition to a substrate having ductility, such as a metal substrate, the coating composition of the present invention may further include a silane-terminated polyether. Since silane-terminated polyethers have a comparatively high reactivity, coating compositions containing silane-terminated polyethers are preferably two-component systems in which the silane-terminated polyether and the hydroxy silicone oil are present in different components. In one embodiment of the present invention, the coating composition comprises the following components: alkoxy silicon resin, silane terminated polyether, hydroxyl silicone oil, aminosilane and a catalyst; wherein, the alkoxy silicon resin and the silane terminated polyether exist in the same component A, and the hydroxyl silicone oil exists in the other component B. When the silane-terminated polyether content is relatively low, for example less than 6 wt%, such as 5 wt%, 4 wt%, 3 wt%, 2 wt%, 1 wt%, based on the total weight of the coating composition, the silane-terminated polyether-containing coating composition may also be a one-component system.
Further, in order to promote the curing of the coating composition and improve the adhesion of a coating film to an inorganic substrate, the coating composition of the present invention may further include an epoxysilane, and the coating composition containing the epoxysilane may be a one-component system or a two-component system. In the two-component system, the epoxysilane and the hydroxysilicone oil are preferably present in separate components. In one embodiment of the present invention, the coating composition comprises the following components: alkoxy silicon resin, epoxy silane, hydroxyl silicone oil, amino silane and a catalyst; wherein, the alkoxy silicon resin and the epoxy silane exist in the same component A, and the hydroxyl silicone oil exists in the other component B.
Furthermore, in order to promote the dispersion of each component and facilitate the leveling and construction of the coating, the coating composition of the invention can also comprise alkoxy silane, and the coating composition containing alkoxy silane can be a one-component system or a two-component system. In the two-component system, the alkoxysilane and the hydroxysilicone oil are preferably present in different components. In one embodiment of the present invention, the coating composition comprises the following components: alkoxy silicon resin, alkoxy silane, hydroxyl silicone oil, amino silane and a catalyst; wherein, the alkoxy silicon resin and the alkoxy silane exist in the same component A, and the hydroxyl silicone oil exists in the other component B.

Examples 1 to 5 and comparative examples 1 to 4
The raw material components of each of the example and comparative example coating compositions are shown in table 1 below.
In table 1, the wt% is based on the total weight of the coating composition.
TABLE 1 feed Components for the examples and comparative examples
And respectively mixing the raw material components of the component A and the component B according to the table to obtain the coating composition. Among them, in examples 1 to 4 and comparative examples 2 to 4, the difference in dynamic viscosity at 25 ℃ between component A and component B was not more than 500 mPas.
The coating compositions of the above examples and comparative examples are different from each other only in raw materials, and are applied to a substrate by the same method to form a film through curing, and specifically comprise the following steps:
(1) mixing: fully stirring and mixing the component A and the component B to obtain a mixture;
(2) and (3) curing: the resulting mixture was applied to a fiber cement board over 1h and allowed to cure for 6 hours at room temperature.
The technical performance indexes of the coatings obtained in the respective examples and comparative examples are shown in table 2 below.
TABLE 2 technical Performance index of each example and comparative example
As can be seen from the above table, the coating compositions of examples 1 to 5 have excellent anti-graffiti performance and repeated adhesion resistance, the ink, the oily pen and the paper towel or the dry cloth for spraying graffiti on the surface of the coating film can be removed, the same area on the surface of the coating film is repeatedly adhered and stripped by the adhesive tape for 50 times, the coating film has no peeling, no obvious light loss and no adhesive residue, the hardness of the coating film is good, and the adhesion force between the coating film and the fiber cement plate also meets the standard requirement.
The coating composition of comparative example 1 had poor graffiti resistance because it contained no hydroxy silicone oil, ink on the surface of the coating film, oil pen and spray graffiti were removed with a citrus-based cleaner, and repeated adhesion resistance was not satisfactory. The coating composition of comparative example 2 contained silane-terminated polyether, alkoxy silicon resin, hydroxy silicone oil and aminosilane, but was not cured after 48h due to the absence of catalyst. The coating composition of comparative example 3 further omits the silane-terminated polyether component on the basis of comparative example 2 and is also uncured after 48 h. The formulation of the coating composition of comparative example 4 was substantially the same as that of example 4 except that the hydroxy silicone oil of example 4 was replaced with the hydroxy silicone resin, and since the hydroxy silicone resin was solid, it was difficult to mix with other components uniformly, and it was necessary to dissolve the hydroxy silicone resin in advance with a solvent, and thus, toluene was additionally added to component B. The coating composition of comparative example 4 was poor in graffiti resistance, ink on the surface of a coating film, oil-based pen and spray graffiti were not removed with absolute alcohol, and repeated adhesion resistance was not satisfactory.
Since the coating compositions of examples and comparative examples were applied to fiber cement boards, in order to increase the adhesion between the coating film and the fiber cement board, an epoxy silane was added to the formulation; if applied to an aqueous acrylic primer, it is contemplated that no epoxy silane be added to the formulation. Further, the coating compositions of examples 1 to 3 and 5, which contain the silane-modified polyether, have excellent coating film flexibility and are suitable for application to various substrates including metal substrates, while the coating composition of example 4, which does not contain the silane-modified polyether, has poor coating film flexibility, is brittle, has limitations on suitable substrates and is not suitable for application to metal substrates.
