DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel emulsion coating composition, and more specifically to a composition comprising a copolymer comprising a fluoroolefin, an alkyl vinyl ether, and a carboxylic acid vinyl ester, using an aqueous dispersion as an organic binder. It is an object of the present invention to provide an emulsion paint with good weather resistance, water resistance, and chemical resistance. [Prior art and its problems] Water-based emulsion paints have superior properties compared to solvent-based paints in that there is no risk of water damage, no solvent odor, no toxicity, and furthermore, the paints can be diluted with water; Although it has practical advantages such as being able to wash painting tools with water, on the other hand, emulsion paints necessarily contain emulsifiers, protective colloids, and thickeners, so they have poor water resistance, weather resistance, There is a problem with chemical resistance. Furthermore, aqueous dispersions of fluoroolefin polymers such as tetrafluoroethylene, vinylidene fluoride, and hexafluoropropylene are known as paints with good weather resistance and chemical resistance, but these require baking at high temperatures. For example, in JP-A No. 57-38845, although the intrinsic viscosity [η] of vinylidene fluoride and hexafluoropropylene copolymer was set to a low molecular weight of 0.1 to 0.5, the polyester was heated at a temperature of 180 to 230°C for 1 to 3 minutes. It requires baking. Therefore, it cannot be applied to applications such as outdoor paints and indoor paints that require a coating film to be formed at room temperature. Furthermore, fluoroolefin monomers are expensive, and it is unavoidable to have a cost disadvantage if the entire copolymer is made of fluoroolefin. [Means for solving the problem] As a result of our earnest efforts to improve the drawbacks of such emulsion paints and fluoroolefin emulsions, we have developed an emulsion in which fluoroolefin is copolymerized with vinyl carboxylate and alkyl vinyl ether at room temperature. Form a coating film with iron,
We have completed the present invention by discovering that it has excellent adhesion to wood, plastic, glass, cement, etc., and has good water resistance, weather resistance, and chemical resistance. That is, the present invention comprises 10 to 55 mol% of fluoroolefin, 10 to 70 mol% of alkyl vinyl ether, and 5 to 80 mol% of carboxylic acid vinyl ester, and the total of the above alkyl vinyl ether and carboxylic acid vinyl ester is 50-90 mol%
The present invention aims to provide an emulsion coating composition comprising an aqueous copolymer dispersion (A) and, if necessary, a pigment (B). Thus, the object of the present invention can be successfully achieved. In the present invention, the fluoroolefins include vinyl fluoride, vinylidene fluoride, chlorotrifluoroethylene, tetrafluoroethylene, 1,1-dichloro-2,2-difluoroethylene, 1-chloro-
2,2-difluoroethylene, 1-chloro-1,
2-difluoroethylene, hexafluoropropylene, 1,1,3,3,3-pentafluoropropylene, 2,3,3,3-tetrafluoropropylene, 3,3,3-trifluoropropylene,
It is a fluoroolefin such as 1,1,2-trifluoropropylene, and preferably one or more of tetrafluoroethylene, chlorotrifluoroethylene, and hexafluoropropylene. The content of such fluoroolefin in the copolymer is 10 to 55 mol%, preferably 20 to 50 mol%.
It is. If the amount is less than 10 mol%, the fluorine content in the copolymer will be low, resulting in poor water resistance and weather resistance. In addition, fluoroolefins tend to copolymerize alternately with alkyl vinyl ethers, but
Because it is difficult to copolymerize with vinyl carboxylates, alkyl vinyl ethers do not homopolymerize, but copolymerizes easily with vinyl carboxylates, and vinyl carboxylates homopolymerize, more than 55 mol% of fluoroolefins are used. It is difficult to contain it. Alkyl vinyl ethers include methyl, ethyl, n-propyl, isopropyl, n-butyl,
It is a vinyl ether having an alkyl group such as isobutyl, t-butyl, isoamyl, n-hexyl, n-octyl, 2-ethylhexyl, or a substituent-containing alkyl group such as hydroxyethyl or hydroxybutyl, preferably having 2 or more carbon atoms. It has 4 alkyl groups. The content of alkyl vinyl ether in the copolymer
The content is 10 to 70 mol%, preferably 30 to 55 mol%. For the reason of the copolymerization reactivity mentioned above, it is desirable that the amount is equal to or more than the fluoroolefin in terms of yield during production, and therefore, this amount is 10 mol%.
If it is less than 70 mol%, the fluoroolefin content will be less than 10 mol%, which is not preferable, and if it exceeds 70 mol%, the fluorine content in the copolymer will be low. Examples of carboxylic acid vinyl esters include vinyl acetate, vinyl propionate, vinyl butyrate, vinyl pivalate, vinyl caproate, vinyl versatate, vinyl laurate, vinyl stearate,
Vinyl benzoate, vinyl pt-butylbenzoate, vinyl salicylate, vinyl monochloroacetate, etc., and preferably aliphatic, aromatic, or alicyclic carboxylic acid vinyl ester having 4 to 17 carbon atoms. The amount of carboxylic acid vinyl ester is 5 to 80 mol%
and preferably 10 to 50 mol%. If the amount is less than 5 mol%, the adhesion of the coating composition to the substrate will be poor, and if it exceeds 80 mol%, the fluorine content in the copolymer will be low, resulting in poor coating film properties. Furthermore, vinyl monomers that can be copolymerized without impairing the effects of the present invention, such as olefins such as ethylene, propylene, butene-1, vinyl chloride, vinyl halides such as vinylidene chloride, and acrylic acid esters (having 1 to 8 carbon atoms). , methacrylic acid ester (having 1 to 8 carbon atoms), acrylamide, N-methylolacrylamide, acrylic acid, methacrylic acid, glycidyl acrylate, hydroxy-containing acrylate, maleic acid, itaconic acid, and other functional group-containing monomers are copolymerized. You can also do it. The aqueous dispersion of the present invention refers to an emulsion or suspension in which a polymer is dispersed in water, and can also include a dispersion in which a finely powdered polymer or a molten polymer is mechanically dispersed, but it is preferably an emulsion polymerized dispersion. This is an aqueous polymer dispersion obtained by In the emulsion polymerization at that time, the above monomer mixture is emulsified with an emulsifier in water or an aqueous solution containing water as the main component and a small amount of organic solvent, and polymerization is carried out by thermal or redox decomposition of the radical initiator (catalyst). Common law methods are common. Examples of emulsifiers include anionic emulsifiers such as alkylbenzene sulfonates, alkylnaphthalene sulfonates, higher fatty acid salts, alkyl sulfate ester salts, alkyl ether sulfate ester salts, phosphate ester salts, perfluoroalkyl fatty acid salts; alkylphenol ethylene oxide additions; nonionic emulsifiers such as ethylene oxide adducts, higher alcohol ethylene oxide adducts, ethylene oxide and propylene oxide block copolymers, and polyvinyl alcohol, polyvinylpyrrolidone, hydroxyethylcellulose, methylcellulose, hydroxypropylcellulose, sodium polyacrylate, and ethylene-maleic anhydride. Water-soluble polymers such as copolymers can be used as protective colloids. As a radical initiator, a water-soluble catalyst such as potassium persulfate or ammonium persulfate, an oil-soluble catalyst such as benzoyl peroxide or t-butyl perbenzoate alone, or a water-soluble reducing agent such as sodium sulfite, Rongarit, ascorbic acid, etc. This is done by using the combination of
Other polymerization systems include chain transfer agents, crosslinking monomers,
A PH buffer can optionally be used. In normal emulsion polymerization, the total amount of monomers
For 100 parts by weight, 50 to 500 parts by weight of water, 1 to 10 parts by weight of emulsifier, and 0.5 to 3 parts by weight of catalyst are used, but the ranges are not limited. The aqueous dispersion used in the present invention has a nonvolatile content of 20 to
65% by weight is preferred. In the coating composition of the present invention, the aqueous dispersion may be contained in an amount of 5 to 100 parts by weight, preferably 20 to 80 parts by weight, per 100 parts by weight of the composition. If the amount is less than 5 parts by weight, the pigment binding strength as an organic binder will be lacking and it will be difficult to form a coating film. Also, 100
In the case of parts by weight, that is, the emulsion alone can be used as a topcoat for paint films, a polish for plastics, wood, etc., and as a protective film. The pigment that can be used in the present invention is not particularly limited, and any pigment that is commonly used in paints may be used. Examples include titanium dioxide (rutile or anatase), iron oxide, zinc oxide, and various colored pigments such as chromates and organic pigments that impart the desired color to the composition. In addition, fillers such as calcium carbonate, calcium oxide, siliceous materials (hydrated silica, fume silica, alumina silicate, calcium, aluminum silicate, magnesium/aluminum silicate, silica aerogel, silica xerogel, asbestos, mica, etc.) may be used. I can do it. Furthermore, the composition of the present invention may contain dispersants such as sodium tripolyphosphate, sodium hexametaphosphate, and sodium polyacrylate, wetting agents such as the nonionic emulsifier, and protective colloids, depending on performance such as workability and stability. Thickeners such as silicone oil, antifoaming agents such as mineral oil, coalescence agents such as dibutyl phthalate, dioctyl phthalate, butyl carbitol acetate, butyl cellosolve, acrylic, vinyl acetate, vinyl chloride, acrylic-styrene, ethylene- It is also possible to add polymer emulsions such as vinyl acetate, ethylene-vinyl acetate-vinyl chloride. [Effects of the Invention] The composition of the present invention can form a film by heating at room temperature or a relatively low temperature, has excellent adhesion to a substrate, and has good water resistance, weather resistance, and chemical resistance. can bring. [Industrial Application Field] The emulsion coating composition of the present invention can be applied to the field of synthetic resin emulsion coatings.
In other words, by increasing the PWC (pigment weight concentration) to 85 to 95%, it can be used as a spray tile paint.
By increasing it to 85%, it can be used as an indoor/outdoor paint, and by mixing a larger amount of sand, it can be used as a sand wall paint, or as a PWC paint.
By setting it to 10 to 50%, it can be used as a gloss paint.
