Description

Paint Compositions for Aerosol Cans

The present invention relates to a paint composition for an aerosol can.

Various aerosol formulations for canned aerosol paint and adhesive systems have been known for many years. One-component aerosol paint and adhesive formulations have been mainstream, and since then, the importance of a two-component paint and adhesive system constituting a two-component paint or adhesive formulation is increasing.

The polyurethane system is an example of a two component aerosol paint system. The two-component polyurethane aerosol formulation contains a hydroxyl group-containing acrylate or polyester resin, and a polyisocyanate as a curing component in a separate chamber from the binder component. This kind of aerosol paint can is used for primers, undercoats, finish coatings, etc., which are preferentially applied to vehicles such as passenger cars, trucks, buses, railways and containers.

The epoxy system is another example of a two component aerosol paint and adhesive system. The epoxy system contains a parent compound of the epoxy resin as a binder and an amine, usually as a curing agent. The two-component epoxy system is used for general industrial and domestic handicrafts, such as a building field, a machine construction industry, in addition to a vehicle purpose. For example, European Patent No. 1427767 B1 discloses a two-component aerosol paint and adhesive system can comprising an epoxy paint and adhesive system particularly suitable for repair purposes. The aerosol paint and adhesive system can includes (1) a parent epoxy resin, (2) a solvent mixture, (3) a propulsion gas, and (4) an epoxy housed in a separate chamber and used as a curing agent for the parent epoxy resin. It includes aerosol formulations based on two-component epoxy technology that includes a curing agent.

This aerosol paint and adhesive system has a problem in that it cannot implement high-quality paint. That is, in order to increase the spraying efficiency during aerosol spraying, the ratio of the solvent mixture is increased and a thin film is formed when the aerosol paint is sprayed by the propellant gas during spraying, which is mainly used for repairs.

On the other hand, the airless spray is a spray painting method such as an airbrush or a spray method in which air is not mixed with the paint, and the paint is pushed through a small tip hole with a high pressure pump. Due to its characteristics, it can be easily seen in shipyards or construction sites. This airless spray has the property of spraying high-viscosity paints at high pressure, so it is possible to paint thick at a time, and there is little paint scattering, so waste is very low, work speed is fast, and it fills in gaps well and has good adhesion. It has the advantage of being excellent. However, it is dangerous because the paint is sprayed at a very high pressure, and if the human body is exposed to the injected paint, it may cause fatal injuries, and the equipment is expensive and management is difficult.

Therefore, it is required to develop an aerosol paint can with excellent adhesion, which is coated with a spray method to be applied to a narrow, difficult-to-work surface, but has a thick coating at once like an airless spray.

Accordingly, the inventors of the present invention have made it possible to improve workability and flowability by controlling the curing rate while controlling the viscosity of the main material in the paint composition for an aerosol can, and to exhibit high adhesion while forming a thick coating film at once, The present invention was completed by developing a paint composition for an aerosol can applicable to various aspects as well as repair.

Accordingly, the present invention makes it a technical solution to provide a paint composition for an aerosol can and a paint composition for a two-component aerosol can capable of forming a high-quality paint and a high-level film.

In order to solve the above problems, the present invention,

In an aerosol paint composition used in an aerosol can in which a paint mixture and a propellant are pressure sealed,

The paint mixture includes at least one of an epoxy resin, a urethane resin, or a silicone resin,

Further including a diluent in the aerosol can, so that the paint mixture and the diluent are included in a weight ratio of 50 to 95: 5 to 50,

Preferably, in the present invention, the thickness of the humidity film formed upon one application by spraying the aerosol paint composition is at least 25 μm.

In addition, preferably, in the present invention, the thickness of the dry film formed by the application of the aerosol paint composition is 100 to 350 µm.

In addition, the present invention in order to solve the other technical problem of the present invention,

It consists of a subject aerosol can that is pressurized and sealed including a subject mixture and a propellant, and a curing agent aerosol can that is pressure-sealed including a curing agent mixture and a propellant, and the contents of the curing agent aerosol can are transferred and mixed to the subject aerosol can and sprayed.

Preferably, in the present invention, when the contents of the curing agent aerosol can are transferred, mixed and sprayed to the main aerosol can, the thickness of the moisture film formed during one application is at least 25 μm.

In addition, preferably, in the present invention, the content of the curing agent aerosol can is transferred to the main aerosol can, mixed, and sprayed to form a dry film having a thickness of 100 to 350 μm.

In addition, preferably, in the present invention, the main mixture is characterized in that it further contains zinc.

The above-described paint composition for aerosol cans of the present invention is a wide range of high-gloss paints, high-transparent lacquers or varnishes by lowering the viscosity of a paint mixture including an epoxy-based resin, a urethane-based resin, and a silicone-based resin with a diluent to improve both workability and flowability. , It has the effect of manufacturing a paint with high surface hardness. In addition, since it is possible to economically implement a highly reliable coating film, there is an effect of reducing the time and cost required for the overall painting process.

Hereinafter, the present invention will be described in detail.

The present invention is a paint composition for an aerosol can, characterized in that it is possible to form a high-level film by improving the workability and flowability of the paint composition for an aerosol can composed of a one- or two-component type.

More specifically, a one-pack paint composition for aerosol cans is an aerosol paint composition used in an aerosol can in which a paint mixture and a propellant are pressure sealed, and the paint mixture contains at least one of an epoxy resin, a urethane resin, or a silicone resin. And, further comprising a diluent in the aerosol can, and the paint mixture and diluent are included in a weight ratio of 50 to 95: 5 to 50.

In particular, the paint mixture is characterized in that it contains at least one of an epoxy-based resin, a urethane-based resin, or a silicone-based resin. Since the resin has a high viscosity, it is required to use an airless device to apply it by a spray method. In the present invention, in order to solve this problem, a diluent is further included in the aerosol can in addition to the paint mixture. As a result, the viscosity of the paint mixture is lowered to improve workability, while controlling the flowability, so that sagging does not occur when spraying with an aerosol can, and can be adhered to the adhered surface as it is sprayed, and a thick high-level film is formed by rapid curing. It is also possible to do.

Accordingly, while forming a thick moisture film of 25 μm or more by one spraying, it is cured at a high speed and additionally sprayed, forming a layered coating, forming a thick dry coating of 100 to 350 μm, which cannot be formed by the conventional aerosol can spraying method. It will be able to form. That is, in forming a coating film using an aerosol can, the present invention improves the paint for aerosol cans, which was limited to repairs by forming a conventional thin coating film, and while realizing the quality of an epoxy, urethane, or silicone-based resin as it is, using an aerosol can It was made to be able to form a coating film simply.

In addition, the diluent may be a general-purpose diluent, but preferably, one or more may be selected from the group consisting of ethylbenzene, xylene, trimethylbenzene, and alcohol, and differently used depending on the resin included in the paint mixture. It is also possible. For example, when the paint mixture is a silicone resin, a diluent including ethylbenzene and xylene may be used. More preferably, 10 to 25% by weight of ethylbenzene and 50 to 90% by weight of xylene may be used.

In this case, it is important to mix the diluent with the paint mixture in a ratio of 50 to 95:5 to 50. This is because when the diluent is included within the above range, the viscosity of the main material is high, so that the workability when spraying the aerosol can decreases, and when it exceeds the above range, the flowability is excessively increased.

Accordingly, the paint composition for a one-component aerosol can of the present invention employs a spraying method on various surfaces including, but not limited to, a metal surface, a plastic surface, a ceramic surface, a wood surface, a cellulose or cellulose-based surface, and a glass fiber surface. By using it, it is possible to provide a coating capable of forming a high-level film while showing excellent adhesion properties.

In another aspect, the present invention is composed of a subject aerosol can that is press-sealed including a subject mixture and a propellant, and a curing agent aerosol can that is pressure sealed including a curing agent mixture and a propellant, and the contents of the curing agent aerosol can are It relates to a two-component aerosol paint composition that is transferred and mixed in a can and sprayed. In the paint composition for a two-component aerosol can according to the present invention, the main mixture includes at least one of an epoxy-based resin, a urethane-based resin, or a silicone-based resin, and further includes a diluent in the main aerosol can, wherein the main mixture and The diluent is included in a weight ratio of 50 to 95: 5 to 50, so that when the contents of the curing agent aerosol can are transferred, mixed and sprayed to the main aerosol can, workability and flowability are improved to form a high level film. That is, the main mixture containing at least one of epoxy-based resin, urethane-based resin, or silicone-based resin has a high viscosity, and thus it is required to use airless equipment to apply it by a spray method. In the main aerosol can, in addition to the main mixture, a diluent is further included so that the main aerosol can is transferred from the main aerosol can to the hardener aerosol can and mixed. As a result, when the main mixture is reacted with the curing agent mixture in a state of low viscosity by the diluent, the viscosity is lowered to improve workability and flowability is controlled, so that sagging does not occur when spraying with an aerosol can, and deposited as it is sprayed. It can be adhered to the surface, and it is possible to form a thick high-level film according to rapid curing.

Accordingly, while forming a thick moisture film of 25 μm or more by one spraying, it is cured at a high speed and additionally sprayed, forming a layered coating, forming a thick dry coating of 100 to 350 μm, which cannot be formed by the conventional aerosol can spraying method. It will be able to form. That is, the present invention is limited to repair, etc. by forming a thin coating film in the prior art in forming a coating film using an aerosol can, as well as enhancing the physical properties of the coating film by manufacturing it in a two-component type, as well as improving the quality of epoxy, urethane or silicone-based resins. While implementing as it is, it is possible to simply form a coating film using an aerosol can.

As an example, the subject mixture is a paint including an epoxy resin, a urethane resin, or a silicone resin, and may be a waterproof, anticorrosive paint, rust preventive paint, heat resistant paint, or the like. In particular, it may be used for heavy corrosion protection such as shipbuilding and offshore structures, and when used as the rust-preventing paint, zinc may be further included in the main mixture.

In addition, the diluent may be a general-purpose diluent, and preferably, it is possible to use differently depending on the resin contained in the main mixture. In general, paint manufacturers manufacture exclusive thinners that are applied to paints by mixing solvents of various components based on the unique formulation of the paints. Therefore, when using a dedicated diluent, the solvent power and evaporation rate of the resin, etc. It is possible to prevent the occurrence of problems such as poor smoothness and flowability, and excessive dust generation.

As an example, the diluent may be used by selecting one or more from the group consisting of ethylbenzene, xylene, trimethylbenzene, and alcohol. More specifically, when the main mixture is an epoxy resin, a diluent including trimethylbenzene isomer, butanol, ethylbenzene, and xylene may be used. More preferably, 10 to 25% by weight of trimethylbenzene isomer, 30 to 45% by weight of n-butanol, 5 to 10% by weight of ethylbenzene, 20 to 30% by weight of xylene, and 20 to 30% by weight of naphtha, a light aromatic compound solvent. A diluent can be used. At this time, trimethylbenzene is added while the light aromatic compound solvent naphtha having a relatively high volatilization rate is added, so that a check phenomenon on the surface of the coating film that occurs due to a difference in drying speed between the upper and lower portions during the formation of the coating film does not occur. In addition, the n-butanol increases compatibility with the amine type and amide type used as a curing agent for an epoxy resin, thereby effectively lowering the viscosity of a paint composition for an aerosol can.

As another example, when the base mixture is a urethane-based resin, a diluent including acetate, ethylbenzene, and xylene may be used. More preferably, a diluent comprising 40 to 50% by weight of acetate, 10 to 20% by weight of ethylbenzene, and 40 to 50% by weight of xylene may be used. At this time, acetate has a strong dissolving power, a low boiling point, and a fast volatilization rate, so that it is possible to control workability and flowability while effectively lowering the viscosity.

In this case, it is important to mix the diluent with the paint mixture in a ratio of 50 to 95:5 to 50. This is because when the diluent is included within the above range, the viscosity of the main material is high, so that the workability when spraying the aerosol can decreases, and when it exceeds the above range, the flowability is excessively increased.

In addition, a valve may be used to transfer the contents of the curing agent aerosol can to the main aerosol can. 4 shows a valve (adapter) used in the present invention as a preferred embodiment of the present invention. At this time, in order to allow the contents of the curing agent aerosol can to be transferred to the main aerosol can using the valve, the curing agent aerosol can is configured to have an internal pressure of at least 1.5 to 2 bar higher than that of the main aerosol can. At this time the pressure inside both aerosol cans is preferably also higher than the ambient pressure, i.e. above 1 bar, such that the propellant forces the contents of each aerosol can from the aerosol can. In this case, the aerosol can may be a tin can, an aluminum can, or a plastic can, but is not limited thereto.

In addition, in using the two-component aerosol paint composition of the present invention, the pressure difference of 1.5 bar to 2 bar described above ensures that the hardener component is efficiently transferred to the main aerosol can through the valve. When the valve interconnects the two aerosol cans, the pressure difference also prevents the paint component from accidentally entering the hardener aerosol can. Preferably, the valve can be made of any solid material suitable for transport purposes. Suitable but non-limiting valve materials include plastics; Metals such as steel; And ceramics, more preferably not interacting with the components of the curing agent can, ie reacting, decomposing, or otherwise affecting.

In addition, the present invention relates to a method of construction using the above-described aerosol can paint composition. Specifically, pre-treating the background surface; And a coating film forming step of forming an advanced film using the above-described aerosol can paint composition on the pretreated base surface. The aerosol can paint composition may be a one-component or two-pack type, and the present invention provides a metal surface, a plastic surface, a ceramic surface, a wood surface, a cellulose or cellulose-based surface, and a glass fiber even when the aerosol can paint composition is used. It is possible to form a high-level film while exhibiting excellent adhesive properties on various substrates such as the surface. In other words, while forming a thick moisture film of 25㎛ or more by one spraying, it is cured at a high speed and additionally sprayed to form a layered coating, thus forming a dry coating of 100-350㎛ level that cannot be formed by spraying using a conventional aerosol can. Since it can be formed thick, efficient construction is possible only by spraying an aerosol.

Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the drawings.

FIG. 1 shows a paint composition for an aerosol can using a main aerosol can and a curing agent (product name ENA 303) mixed with different ratios of an epoxy resin (product name: ENA 301) and a diluent (product name: GTA 220) as a main mixture. It shows the experimental results.

Referring to FIG. 1(a), when the epoxy resin and the diluent, which are the main mixture, were filled in 1:1 to 1:0.5, it was confirmed that the formed coating film was 175 μm to 350 μm, and a thick coating film was formed. , When the diluent was added in a ratio of 1:1 to 1:0.7, the paint was diluted when spraying due to excessive injection of the diluent, and most of it was sprayed like water and flew away, indicating that the cotton was not properly formed. Was confirmed. However, it was confirmed that workability was improved when the diluent was added in a ratio of 1:0.5.

In addition, referring to FIG. 1(b), when the main mixture and the diluent were filled in a weight ratio of 1:0.3 to 1:0.1, it was confirmed that a coating film of 350㎛ or more was stably formed when the coating film was formed (hold up). It was found to have excellent performance and improved flow, so that sagging did not occur. In particular, when the main mixture and the diluent were filled in a weight ratio of 1:0.1, WET 600-650㎛ was the most optimal when measuring hold up.

Further, the viscosity of the main body and the thickness of the coating film formed by spraying the aerosol were tested. At this time, the viscosity of the subject according to the addition ratio of the diluent is shown in Table 1 below.

GTA220 Thinning(%) Viscosity (poise) 100% 0.11 70% 0.15 50% 0.26 30% 0.6 25% 0.79 20% 1.05 15% 1.5 10% 2.14 ENA301 (Part A) 8.04 ENA303 (Part B) 4.04 Part A+B Mix 6.72

As can be seen in Table 1 above, it can be seen that the viscosity of the main material exhibits a remarkably low value by the addition of a diluent and then increases again by mixing the curing agent. At this time, the viscosity was measured for a liquid product containing no propellant.

In addition, the thickness of the coating film formed during the aerosol coating operation according to the above-described diluent addition ratio was measured. At this time, the above operation was carried out without a time interval between painting operations in a manner in which repainting was performed immediately after one application using an aerosol can. The measured results are shown in Table 2 below.

Referring to Table 2 below, it was confirmed that when the addition ratio of the diluent was 30%, a coating film of 50 µm or more and at least 25 µm or more can be formed according to one coating. In addition, when the addition ratio of the diluent was 30% or less, it was confirmed that the thickness of the dry film was formed to be about 150 µm or more when applied n times or more, and a dry film having a level of about 100 µm was formed up to 70% of the diluent ratio. However, when the addition ratio of the diluent was 50% or more, sagging occurred due to the aerosol characteristics, and it was found that workability was better than that of 30% or less, and most preferably, when mixed at a ratio of 10%, an excellent high-altitude film was formed while workingability. It was confirmed that this improved.

When the coating is repeated several times in this way, even if the coating is carried out without time intervals between coating operations, when the addition of the diluent is less than 50%, it has been shown to be excellent in workability and flowability, preferably 30% of the diluent, more preferably When mixed at a 10% ratio, it was confirmed that a thick dry coating was formed, as well as excellent workability and flowability. This means that the paint composition for an aerosol can of the present invention remarkably improves workability and flowability to shorten working time and form a high-quality coating film.

In addition, Table 3 below shows the contents of an example in which the diluent ratio was varied for 13 one- or two-component paint compositions, and the diluent was composed to include an epoxy-based resin, a urethane-based resin and a silicone-based resin, To include in %, a diluent suitable for the resin was added.

Referring to Table 4 and FIG. 3, it was confirmed that not only excellent workability and film formation were excellent in Examples 1 to 13, but also excellent holding power, appearance, and excellent pen knife adhesion. In the drying test as well, it was found that the paints used in the examples were similar to the original physical properties, and it was confirmed that the aerosol can paint composition was used to improve workability and to obtain a high-quality coating film.
