Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aqueous emulsion type aerosol composition.

Conventional technologies and their problems Aerosol compositions generally contain organic solvents as essential components, so they are considered dangerous substances under the Fire Service Act, and various restrictions are placed on their handling, storage, etc. . For this reason, water-based aerosol coating compositions using water-soluble resin as a binder have been developed (for example, Japanese Patent Publication No. 53-34207, Japanese Patent Publication No. 58-4945@,
(See Publications No. 59-32502, No. 59-52913, etc.). However, the above aerosol coating composition has the following drawbacks. In other words, the water-soluble resins used as binders in these compositions require the use of hydrophilic organic solvents during their manufacture, and when they are made into paints, they must be dried at room temperature unless the main component of the diluent is an organic solvent. It cannot be used as a mold paint, and therefore, the aerosol composition cannot be classified as a non-dangerous substance under the Fire Service Act.

Furthermore, aerosol coating compositions are also known in which the vehicle is a synthetic resin emulsion obtained by emulsion polymerization in the presence of a conventional surfactant (for example, JP-A-54-314
Publication No. 45, Publication No. 54-32540, Publication No. 54-32
541 @ Publication, Publication No. 54-33545, Publication No. 54-3
(See Publication No. 3546, etc.). However, such aerosol coating compositions also have the following drawbacks.

That is, the stability of synthetic resin emulsion particles is largely maintained by the emulsifier adsorbed on the surface of the particles, and therefore, the particles remain in contact with the propellant contained in the composition for a long period of time in the aerosol container. If the emulsifier comes into contact with the emulsion particles at a temperature higher than The aerosol coating composition has the disadvantage of causing clogging, and therefore is not suitable for practical use.

Furthermore, an aerosol coating composition has also been developed in which a binder is a dispersion obtained by dispersing a resin obtained by solution polymerization in a water-soluble organic solvent in water (see JP-A-60-137970). ). However, such aerosol coating compositions also have the following drawbacks. That is, the particle size of the emulsion obtained by emulsion polymerization can be precisely controlled by adjusting the amount of emulsifier used, etc., but in solution polymerization, the particle size of the emulsion obtained by solution polymerization is simply dispersed in water using mechanical energy. It is difficult to accurately control the particle size of the particles, and therefore valve clogging, mistakes, and other defects are inevitable. Furthermore, compared to synthetic resins obtained by emulsion polymerization, solution polymerization only yields synthetic resins with a lower molecular weight. Since polymerization cannot be expected, disadvantages in terms of coating film properties cannot be avoided. Moreover, in the above method, it is almost impossible to separate the resin produced by solution polymerization from the water-soluble organic solvent, so it is inevitable that the water-soluble organic solvent will be mixed into the aerosol coating composition. This composition also cannot be considered a non-hazardous material under the Fire Service Act. Furthermore, in producing the above aerosol coating composition, a long dispersion step is required after the completion of solution polymerization, which poses problems in terms of ease and economy in producing the composition.

Means for Solving Thinning Problems In view of the current situation, the present inventors have developed a method that does not contain a water-soluble organic solvent as an essential component, has excellent storage stability over a long period of time, and has a method that does not require atomization, etc. We have been conducting extensive research to develop an aerosol composition that will not deteriorate its sprayability and cause clogging of valves. As a result, when a synthetic resin emulsion blended into an aerosol composition is used, which is obtained by emulsion polymerization of a polymerizable monomer in a polymerization reaction system in which a specific amount of a specific emulsifier is present, the present invention It was discovered that the intended purpose of this method could be achieved. The present invention was completed based on this knowledge.

That is, the present invention provides an aqueous emulsion type aerosol composition containing a synthetic resin emulsion, water, and a propellant, in which the synthetic resin emulsion contains 100 parts by weight of a polymerizable monomer in the presence of 5 to 20 parts by weight of a polymerizable emulsifier. The present invention relates to an aqueous emulsion type aerosol composition obtained by emulsion polymerization of the body.

The synthetic resin emulsion blended into the composition of the present invention is
It is obtained by emulsion polymerization of polymerizable monomers in the presence of a polymerizable emulsifier.

The polymerizable emulsifier used in the present invention is not particularly limited, and any conventionally known emulsifier can be used as long as it has polymerizability. Hydrophilic anionic, nonionic or cationic compounds can be suitably used. Specifically, such a polymerizable emulsifier has the general formula (1) Na03SCHCOOCH2CH=CH2R2C-C0
OR' [In the formula, R1 is an alkyl group having 8 to 20 carbon atoms] alkylarylsulfosuccine-1 to alkali salt, general formula (2) (in the formula, R2 is an alkyl group having 12 to 20 carbon atoms); Sodium (glycerin n-alkenylsuccinoylglycerin)borate represented by the general formula % formula % An alkali salt of sulfopropyl maleic acid monoalkyl ester represented by the general formula 4) % formula %) [In the formula, R4 is a hydrogen atom or a methyl group, R5 is carbon v18
~20 alkyl group, n is an integer of 1 to 20] Polyoxyethylene alkyl ester of acrylic acid or methacrylic acid, general formula (5) % formula % [wherein R6 is an alkyl group having 12 to 18 carbon atoms] , M is Na
or NH4), a hydroxyalkylaryl sulfosuccinate represented by the general formula (6) [wherein R7 has 1 carbon number]
3-allyl-2- represented by 2-18 alkyl group]
Examples include human Ooxypropyl-N-alkyl-N, N-dimethylammonium chloride. In the present invention,
These polymerizable emulsifiers can be used alone or in combination of two or more. Among these polymerizable emulsifiers, the alkylaryl sulfosuccinate alkali salt represented by the above general formula (1) is particularly suitable.

Examples of the polymerizable monomer used in the present invention include acrylic acid alkyl esters in which the alkyl group has 1 to 12 carbon atoms (specifically, methyl acrylate, ethyl acrylate,
butyl acrylate, isobutyl acrylate, 2-ethylhexyl acrylate, lauryl acrylate, etc.), methacrylic acid alkyl esters with an alkyl group having 1 to 12 carbon atoms (specifically methyl methacrylate, ethyl methacrylate, butyl methacrylate) , isobutyl methacrylate, M2-ethylhexyl methacrylate, lauryl methacrylate, etc.). In addition, monomers copolymerizable with the above acrylic acid alkyl esters and methacrylic acid alkyl esters, such as styrene, vinyl acetate, vinyl esters of saturated carboxylic acids branched at the α-position, acrylic acid, methacrylic acid, itaconic acid, acrylonitrile, Acrylamide, N-methylol acrylamide, etc. can also be used together with the above acrylic acid alkyl ester or methacrylic acid alkyl ester.

The above-mentioned acrylic acid alkyl ester and methacrylic acid alkyl ester are preferably used in a proportion of at least about 5% by weight or more, preferably about 20% by weight or more in the total monomers.

The synthetic resin emulsion used in the present invention includes 5 to 20 parts of the polymerizable emulsifier in the reaction system of the polymerization when 100 parts by weight (hereinafter simply referred to as "parts") of the polymerizable monomer is emulsion polymerized. Preferably, it is necessary to use a product obtained by adding 8 to 15 parts. If the amount of the polymerizable emulsifier is less than 5 parts, lumps, aggregates, etc. will occur during polymerization,
It is difficult to obtain a homogeneous emulsion polymer, and the obtained emulsion has a large particle size and poor stability. Therefore, when the emulsion is blended into an aerosol composition, valve clogging occurs, etc. It becomes difficult to achieve the intended purpose. Conversely, the amount of polymerizable emulsifier is 20
If the amount is more than 20 parts, the water resistance of the dry film of the resulting emulsion will be significantly reduced, causing problems in its practicality as a vehicle for paints, etc. However, even if the amount used is more than 20 parts, The effect of the period does not improve that much, and it is not economically favorable.

In producing the synthetic resin emulsion used in the present invention, the production method is not particularly limited, and any conventional emulsion polymerization method may be used.

For example, the above polymerizable monomer and polymerizable emulsifier are emulsified and dispersed in a predetermined amount of water, and a polymerization initiator, such as peroxide such as ammonium persulfate, potassium persulfate, sodium persulfate, hydrogen peroxide, etc. sodium bisulfite,
What is necessary is to add a combination with a reducing agent such as L-ascorbic acid, etc., and carry out redox polymerization at room temperature or high temperature polymerization under heating. The method of charging the polymerizable monomer may be a batch method or a continuous feeding method. Alternatively, a method may be adopted in which a portion is first polymerized and then the remaining portion is continuously fed. Among these methods, it is preferable to employ a continuous feeding method, and in this case, a method in which water and a polymerizable emulsifier are used to feed the polymerizable monomer emulsion as a polymerizable monomer emulsion is particularly suitable.

The particle size of the synthetic resin emulsion used in the present invention is not particularly limited, but is between 0.2 μm and 0.2 μm.
．． A thickness of about 0.01μ is suitable.

The synthetic resin emulsion used in the present invention may also be obtained by further reacting a third component such as a known reactive dye or colloidal silica.

The amount of the synthetic resin emulsion blended into the composition of the present invention is usually about 1 to 40 parts as resin solids per 100 parts of the composition of the present invention.

As the propellant to be incorporated into the composition of the present invention, a wide variety of conventionally known propellants can be used as long as they are hydrophilic propellants, and typical examples include dimethyl ether. In the present invention, the hydrophilic propellant may be, for example, a fluorocarbon such as trichloromonofluoroethane, dichloromonofluoromethane, or TSKU00 tetrafluoroethane, or a hydrophilic propellant such as n-butane, isobutane, propane, liquefied petroleum gas (LPG), or ethane. It can also be used in combination with hydrophobic propellants such as carbon. When a hydrophilic propellant and a hydrophobic propellant are used together, it is preferable to use the hydrophobic propellant within a range that does not impair the properties of the hydrophilic propellant.

The amount of the propellant to be blended into the composition of the present invention is usually about 35 to 60% by weight.

The synthetic resin emulsion of the present invention includes water-soluble polymers such as hydroxyethylcellulose boxymethylcellulose, polyvinylpyrrolidone, polyvinyl alcohol, polyacrylic acid, polyethylene oxide, polyethylene glycol, maltose, ercinane, pullulan, dextrin, levan, mannan, etc. , 1-lagant gum, guar gum, xanthan gum, carrageenan, pectin, hydroxystarch, and other water-soluble polysaccharides in any proportion. These are all soluble in water without the addition of organic solvents, so the aerosol products of the present invention are non-hazardous.
It does not cause any problems such as exceeding the mild flammability indicator. In other words, the fact that both can be used together in any ratio is extremely advantageous in freely adjusting the physical and chemical properties of each film. More specifically, by appropriately blending the synthetic resin emulsion with the water-soluble polymer, etc., the temporary binder effect can be changed to a stronger one. On the other hand, by adding the above-mentioned water-soluble polymer or the like to the above-mentioned synthetic resin emulsion, it is also possible to adjust the excessively strong binding force to an appropriate range.

The composition of the present invention may optionally contain dyes, pigments, coloring pastes, pharmacologically active ingredients such as herbicidal ingredients, insecticidal ingredients, film-forming aids, thickeners, anti-settling agents, antifoaming agents, and anti-sagging agents. Various conventionally known components such as rust preventives, chelating agents, preservatives, and antifungal agents can be appropriately blended.

Effects of the Invention The aqueous emulsion type aerosol composition of the present invention does not contain a water-soluble organic solvent as an essential component, so it is a non-hazardous substance under the Fire Service Act, and has excellent long-term storage stability. It is extremely suitable for practical use because it does not cause clogging of valves due to deterioration of spray suitability such as chemical deterioration.

Therefore, the aqueous emulsion aerosol composition of the present invention includes, in addition to an aqueous emulsion aerosol coating composition, an aqueous emulsion aerosol pesticide composition, an aqueous emulsion aerosol insecticide composition, an aqueous emulsion aerosol adhesive composition, and an aqueous emulsion aerosol adhesive composition. It can be suitably used as an emulsion type aerosol glue composition.
