[Industrial Field of Application] The present invention relates to a film-forming material composition, and more particularly to a film-forming material composition capable of forming a colored film with excellent dustproof properties on the surface of a silicone elastomer. [Prior Art and Problems] Various types of polyorganosiloxane compositions that cure at room temperature to become rubber-like elastic bodies are known. For example, acetoxy, alkoxy, dialkylketoxime, dialkylamino, dialkylaminoxy, N-methylamide groups, etc. to which silicon atoms are bonded can be hydrolyzed into polydiorganosiloxane whose both ends are capped with silanol groups. Polyorganosiloxane compositions using organosilicon compounds having groups as crosslinking agents are widely used in the construction industry, automobiles, electrical equipment, and other industries. In the construction industry, this composition is collectively called silicone sealant, and is widely used for waterproof sealing of voids in building wall materials such as concrete and aluminum plates, for fixing glass to sash, and for adhering glass to glass. Silicone sealants have particularly excellent weather resistance, durability, heat resistance, and cold resistance, have little change in physical properties due to temperature, do not deteriorate due to ozone or ultraviolet rays, and are easy to work with during construction.
Demand for high-rise buildings and other buildings is increasing. In recent years, it has also begun to be used as a coating material by applying this main polyorganosiloxane composition to roofs and walls to form a silicone elastic layer with excellent waterproofness and weather resistance. In addition to the above-mentioned characteristics, these architectural coating materials must be able to be colored to any desired color tone to match the design of the building.
Furthermore, it is required that there is no discoloration or staining over a long period of time. However, although silicone elastomers generally have the excellent properties mentioned above, they tend to collect dust easily because the main component, polydiorganosiloxane, is a dielectric, and polysiloxane, which does not participate in crosslinking, tends to collect dust easily. This has the disadvantage that the dust is not washed away by rainwater, and staining progresses significantly, since the particles move from the inside of the elastic body to the surface and cover the dust, making it water repellent. Furthermore, since various inorganic powders are used as fillers for the purpose of imparting physical properties and workability, it has not always been possible to adjust the color to any desired color tone. In order to prevent such staining, the present inventors previously developed an organosilicon compound containing an organoaminoxy group and SiO 2 units and R 1 3 SiO 1/2
A mixture or condensation reaction product of a benzene-soluble polyorganosiloxane consisting of It was discovered that by coating a silicone elastic body, it is possible to form a dustproof coating film with excellent dustproof properties on the surface (Japanese Patent Application Laid-Open No.
57-162763). The present inventors next attempted to disperse coloring pigments in this coating for the purpose of coloring the coating film. However, coating film-forming materials to which pigments have been added have been unable to form a uniform coating film due to significant pigment separation during application, and satisfactory results have not been obtained. As a result of investigation, the present inventors discovered that a coating film-forming material composition free from pigment separation could be obtained by using fumed silica surface-treated with an organosilicon compound together with a colored pigment (Japanese Patent Application Laid-Open No. 59-2011). −100170). This coating film-forming material composition was a two-pack type in which the organosilicon compound containing an organoaminoxy group was packaged separately and the two were mixed at the time of use, but the viscosity increased over time from mixing to use. In addition to the problem that the gloss changes, there is also the problem that the fumed silica aggregates with the coloring pigment during storage and further causes sedimentation. [Means for Solving the Problems] As a result of intensive studies on methods for solving these problems, the inventors of the present invention have found that an organic material selected from the group consisting of fatty acids, resin acids, and naphthenic acids can be used instead of the above-mentioned fumed silica. The present invention was completed by discovering that the use of an aluminum salt of an acid not only solves all of the above-mentioned problems, but also facilitates the dispersion of colored pigments during production. That is, the present invention comprises: (A) 100 parts by weight of an organosilicon compound having an average number of more than two organoaminoxy groups in the molecule; (B) (a) SiO 2 units and the following formula: R 1 3 SiO 1 /2 ( in the formula, R 1 represents the same or different monovalent substituted or unsubstituted hydrocarbon group) polyorganosiloxane present in an amount of 0.4 to 1.0 mol per silicon atom, with 0.0004 to 1 hydroxyl group bonded to each silicon atom
(b) a mixture of 10 to 1000 parts by weight of a polydiorganosiloxane capped at both ends with silanol groups having a viscosity of 30 to 2,000,000 cSt at 25°C, or a condensation reaction product thereof; (A)
10 to 1000 parts by weight per 100 parts by weight; (C) 5 to 500 parts by weight of a coloring pigment per 100 parts by weight of the total amount of (A) and (B); (D) a hydrocarbon solvent; (A) ) to 500 parts by weight per 100 parts by weight of the total amount of (A) to (E); and (E) 0.05 part by weight or more to 100 parts by weight of the total amount of (A) to (D); 100 parts by weight or less of an aluminum salt of an organic acid selected from the group consisting of fatty acids, resin acids, and naphthenic acids based on 100 parts by weight of the total amount of ) and (B); This relates to a forming material composition. The aminoxy group-containing organosilicon compound as component (A) used in the present invention includes silane derivatives and linear, cyclic or branched siloxane derivatives. Examples of organic groups bonded to silicon atoms include alkyl groups such as methyl, ethyl, propyl, butyl and hexyl groups, and aryl groups such as phenyl. In addition, it is necessary to have an average number of organoaminoxy groups in one molecule of more than two, and a film is formed within a short time after application, resulting in a film with better stain prevention properties. It is preferable to have an average of 2.5 or more. Examples of the organic group bonded to the organoaminoxy group include two monovalent hydrocarbon groups such as a methyl group, ethyl group, propyl group, butyl group, or cyclohexyl group; or two monovalent hydrocarbon groups such as a tetramethylene group or a pentamethylene group. One example is a valent hydrocarbon group. Among these, it is preferable to use an ethyl group for reasons such as ease of obtaining raw materials, ease of synthesis, reactivity, and ease of volatilization of the organohydroxylamine released. Examples of such organoaminoxy group-containing organosilicon compounds include the following. Hereinafter, for the sake of brevity, the following abbreviations will be used for each organosilicon compound. [Abbreviations] Me: methyl group, Et: ethyl group, Bu: butyl group,

Benzene soluble polyorganosiloxanes are usually used. As R 1 ,
Alkyl groups such as methyl group, ethyl group, propyl group, butyl group, amyl group, hexyl group, octyl group, decyl group; alkenyl groups such as vinyl group; aryl groups such as phenyl group; β-phenylethyl group, β
-Aralkyl groups such as phenylpropyl groups and some of these hydrogen atoms are chlorine atoms, fluorine atoms,
Examples include those substituted with a nitrile group.
Among these, from the viewpoint of easy synthesis, good weather resistance, and reactivity with (b), it is preferable that 90 mol% or more of R 1 is a methyl group, and all of R 1 is a methyl group. It is more preferable that
The amount of R 1 3 SiO 1/2 units is per mole of SiO 2 units.
If the R 1 3 SiO 1/2 unit is less than 0.4 mol, it will be difficult to stably obtain a benzene-soluble low molecular weight product, and it will gel during synthesis or storage, resulting in insoluble and infusible It tends to form polymers. or,
If the R 1 3 SiO 1/2 unit is more than 1.0 mol, the reactivity will be low when condensing with the silanol-terminated polydiorganosiloxane (b), making it possible to form a film with sufficient dust prevention effect and high toughness. It becomes difficult to obtain the composition. The polyorganosiloxane (a) must have 0.0004 to 1 hydroxyl group per silicon atom to which silicon atoms are bonded. The hydroxyl group
If the number is less than 0.0004, the strength of the coating film will decrease, and if it exceeds 1, the crosslinking speed will be too high and sufficient pot life will not be obtained, and the coating film will become brittle. Such polyorganosiloxane is made by adding a tetrafunctional silicon-containing compound selected from alkyl silicates such as ethyl silicate and propyl silicate, partial condensates thereof, silicon tetrachloride, and water glass to trimethylchlorosilane, trimethylchlorosilane, and water glass in the presence of a solvent. It can be obtained by cohydrolyzing with a triorganochlorosilane such as dimethylvinylchlorosilane or dimethylphenylchlorosilane and removing by-products by conventional means. The solvent used at this time is usually benzene, toluene,
Hydrocarbons such as xylene, gasoline, n-hexane, and n-heptane are used. The silanol-terminated polydiorganosiloxane (B) (b) used in the present invention has a substantially chain siloxane skeleton, and has a
A material having a viscosity of 2,000,000 cSt, preferably 1,000 to 200,000 cSt is used. If the viscosity is less than 30 cSt, the resulting film will have poor toughness and flexibility, and if it exceeds 2,000,000 cSt, the viscosity of the composition will increase, impeding workability. The organic group to be bonded to the silicon atom is exemplified by the same one as R 1 in (a), and it should be considered to balance the viscosity of the composition and the necessary physical properties, and quickly cause a condensation reaction with the polyorganosiloxane in (a). This is because the intermediate is easily obtained industrially, and when forming a dust-proof film for sealing the joints of buildings or coating the surface of buildings, it can be cured quickly at room temperature in places that are difficult to heat. , and UV resistance, it is preferable that all of them are methyl groups. However, depending on the use and required properties,
Phenyl groups up to 20 mol%, 10 mol%
A vinyl group may be introduced within the range up to . The polyorganosiloxane (a) and the silanol-terminated polydiorganosiloxane (b) may be used in the form of a simple mixture, or may be co-condensed beforehand. Cocondensation is carried out by mixing the two and heating preferably in the presence of caustic potash, caustic soda or an organic peroxide. The polyorganosiloxane (a) is usually obtained as a hydrocarbon solution with a solid content of 30 to 60% by weight, but if necessary, a solvent is added, then the silanol-terminated polydiorganosiloxane (b) is added, and the mixture is mixed. It can also be obtained by heating the system. The solvent used is preferably a hydrocarbon solvent, with toluene and xylene being particularly preferred.
The heating temperature is preferably in the range of 80 to 150°C, and in particular,
It is advantageous for temperature control to utilize the reflux temperature of the added solvent. This condensation reaction may be continued until completion, or may be stopped in a state of partial condensation. The blending ratio of component (a) and component (b) is 10 to 1000 parts by weight, preferably 20 to 500 parts by weight, of (b) to 100 parts by weight of (a). The reason for this is that if the amount of (b) is more than 1000 parts by weight, the required dustproof effect cannot be obtained, and if it is less than 10 parts by weight, the flexibility and toughness of the film will decrease. The amount of (B) to (A) is: (B) to 100 parts by weight of (A)
The amount is 10 to 1000 parts by weight, preferably 25 to 500 parts by weight. The reason for this is that if the amount of (B) is more than 1000 parts by weight, the desired dustproof effect cannot be obtained, and if it is less than 10 parts by weight, the flexibility and toughness of the film will decrease. The colored pigment (C) used in the present invention is a component for imparting a desired color tone to the coating film, and may be selected from either inorganic pigments or organic pigments. Inorganic pigments include titanium oxide, carbon black,
Examples include titanium yellow, chrome green, red iron, and ultramarine blue. Examples of organic pigments include permanent yellow, toluidine red, phthalocyanine blue, and phthalocyanine green.
The blending amount of these color pigments is the total amount of (A) and (B) 100
It ranges from 5 to 500 parts by weight. The reason for this is that if the amount of (C) is less than 5 parts by weight, the hiding power of the coating film will be insufficient, while if it is more than 500 parts by weight, the flexibility and toughness of the coating film will decrease, and the This is because adhesiveness decreases. The hydrocarbon solvent (D) used in the present invention is benzene, toluene, xylene, n-hexane, n-
-Heptane, cyclohexane, gasoline, etc. are exemplified. Among these, due to its moderate volatility, solubility with the condensation reaction product of (A), and ease of handling,
Toluene or xylene are preferred. The amount of (D) is based on 100 parts by weight of the total amount of (A) to (C).
It ranges from 20 to 500 parts by weight. If the amount of (D) is less than 20 parts by weight, the coating film forming material becomes highly viscous, reducing work efficiency, and the coating film formed is thick, so that the properties of the underlying silicone elastomer are not fully exhibited. Not done. On the other hand, if the amount is more than 500 parts by weight, the film formed in one application will be thin, and sufficient hiding power and dustproofing effect will not be obtained, resulting in the need to apply multiple coats.
Work efficiency decreases. Component (E) used in the present invention imparts appropriate thixotropic properties to the composition, prevents pigment separation and sagging during application, and enables the formation of a uniform coating film without uneven color. Additionally, it works to prevent pigments from settling or agglomerating during retention. Furthermore, this (E)
The film-forming material composition according to the present invention using the component as a thixotropic property-imparting agent is superior to the film-forming material composition using fumed silica surface-treated with an organosilicon compound which is also a thixotropic property-imparting agent. , is characterized in that after mixing an organosilicon compound containing an organoaminoxy group with other components, temporal changes such as an increase in viscosity or an increase in the gloss of the coating film are extremely small. The other component (E) also functions as a pigment dispersion aid to facilitate the dispersion of the colored pigment (C) during production. Component (E) is selected from aluminum salts of organic acids selected from the group consisting of fatty acids, resin acids, and naphthenic acids; fatty acid salts such as aluminum palmitate, aluminum stearate, and aluminum oleate; Examples include resinates such as aluminum pimarate and aluminum salts of naphthenic acid, collectively referred to as aluminum naphthenate. These (E) components may be monosalts, di-salts, tri-salts, or a mixture. The amount of component (E) used is the total amount of (A) to (D).
It is necessary that the amount is 0.05 parts by weight or more per 100 parts by weight, and it is necessary that it is not more than 100 parts by weight per 100 parts by weight of the total amount of (A) and (B). (E)
If the amount of the component is less than this, the thixotropic properties will not be sufficiently imparted, causing pigment separation and sagging, which will not only prevent the formation of a uniform coating film, but also make it easier for pigments to settle during storage. Undesirable. On the other hand, if the amount of component (E) is larger than this, the physical strength of the coating film formed may decrease,
This is also undesirable because it tends to cause loss of gloss and uneven shine. In addition, powders without coloring power such as zinc carbonate, magnesium carbonate, and calcium carbonate may be used as fillers. It is also possible to use unsurfaced fumed silica or crushed silica to provide reinforcement to the coating. Furthermore, in order to obtain a coating film-forming material with low viscosity, excellent workability, and good wettability to the surface of the silicone elastomer, it is preferable to use a volatile organosilicon compound having a boiling point of 70 to 250° C. under normal pressure. This volatile organosilicon compound is a silane or siloxane that does not contain unstable groups, and must have appropriate volatility, in other words, a boiling point in the range of 70 to 250°C. If the boiling point is lower than 70℃, it will volatilize early during application and will not work effectively.
If the temperature is higher than °C, drying properties will be poor and film formation will be slow. Specifically, silanes such as dimethyldiethylsilane and trimethylbutylsilane, linear siloxanes such as hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, and dodecamethylpentasiloxane, and 3-
Trimethylsiloxane-1,1,1,3,7,
Branched siloxanes such as 7,7-heptamethyltrisiloxane, hexamethylcyclotetrasiloxane, octamethylcyclotetrasiloxane,
Examples include cyclic siloxanes such as decamethylcyclopentasiloxane. Among these, methyl-based siloxane is preferred because it is easy to synthesize, and octamethylcyclotetrasiloxane is more preferred from the standpoint of appropriate volatility. The coating film forming material composition of the present invention usually comprises (B) and (D).
Two components: a component in which (C) and (E) are dispersed, and a component (A).
The components are stored separately and the two are mixed together before use. When dispersing (C) and (E) in (B) and (D), use a sand mill, three rolls,
It is advantageous to use equipment such as attritors, ball mills and the like. In addition, the application work involves brush painting,
This can be done by any method such as roll coating or spraying. [Effects of the Invention] The coating film forming material composition of the present invention does not cause pigment separation during application, has low viscosity, has thixotropic properties, and has good wettability to silicone elastomer. A uniform coating film without unevenness can be formed on the surface of the silicone elastomer, and the coating workability is good. Furthermore, the formed coating film has excellent dust resistance and weather resistance, so it can maintain its initial color tone and appearance for a long period of time. Therefore, the film-forming material composition according to the present invention is particularly suitable as a top coat material for silicone elastic coating materials used on the exterior walls of buildings, which has both coloring and dust-proofing effects. [Examples] The present invention will be explained below with reference to Preparation Examples and Examples. The following abbreviations will be used below for simplicity.

parts, 100 parts of S-2, 100 parts of rutile titanium oxide,
10 parts of titanium yellow, 0.15 parts of red iron, 0.1 part of carbon black and aluminum soap shown in Table 4,
Atomized silica surface-treated with hexamethyldisilazane (comparative example), a volatile organosilicon compound, and a hydrocarbon solvent were uniformly dispersed using a sand mill. Next, the organosilicon compounds shown in Table 4 were mixed to obtain samples 41-46. However, sample 45 is a comparative example in which surface-treated fumed silica was used instead of fatty acid aluminum salt, and sample 46 is a comparative example in which fatty acid aluminum salt was not used. Tests similar to those in Example 2 were conducted using these samples. . The results are also shown in Table 4.
