Epoxy coating agent of law viscosity

The present invention relates to an epoxy low-viscosity molding coating, and more particularly to a resin component containing a liquid epoxy as a main component and containing a non-reactive diluent, a plasticizer, a flocculant, an antifoaming agent, and a curing agent, an accelerator and a prereactive agent. It consists of a three-component composition consisting of a hardening component and a small amount of coagulation-controlling component comprising a modified alicyclic amine, a non-reactive diluent, and a catalyst. A low viscosity epoxy molding coating is prepared by blending the three-component component under optimum conditions. If it is applied to the surface of accessories, ornaments or walls by mixing pigments, metal powders, and various accessories, it is excellent in flow and cohesiveness. Very good in applicability to fine three-dimensional accessories. The present invention relates to an epoxy low-viscosity molding coating having a new composition, which can not only greatly increase the beauty of the wall, but also can be easily applied to various molding surfaces due to its excellent durability, transparency, and various physical properties.

Conventional molding coatings containing epoxy as the main component are the epoxy coatings for planks having excellent transparency and elasticity of the finished product in Korean Patent Publication No. 95-18346, containing 90% by weight of epoxy resin and 10% by weight of dibutyl phthalate. Base resin liquid; A curing agent liquid containing 55 wt% of a curing agent, 10 wt% of a curing accelerator, 15 wt% of nonylphenol, 8-11 wt% of an epoxy resin, 12-15 wt% of a curing retarder, and 0-4 wt% of dibutyl phthalate. A two-part epoxy coating agent for planks has been proposed, which comprises blending an epoxy resin to be used as a base resin liquid in a curing agent liquid, and blending dibutyl phthalate with a base resin liquid or a base resin liquid and a curing agent liquid. And the exclusion of the use of additives that give off strong toxic and odorous odors.

However, this coating agent is a flowing type, so it can be applied only to a flat plate type coating, but it is difficult to apply in three-dimensional accessories, and is difficult to apply in three-dimensional accessories. There was an impossible problem.

Conventional accessories and jewelry molding coatings that are commonly used are also made of epoxy resins. Due to the characteristics of polymer resins, the self-flowing properties are strong, and they can have cohesiveness only in high viscosity conditions. Has not escaped from stereotypes, such as not being able to make good use of micromachinability. In particular, in the high viscosity state of the molding coating, it is not possible to blend various accessories smoothly, and the leveling and workability are very low, and thus, there are many difficulties in terms of use and quality.

As described above, the accessory, which is a typical form of handiwork, has many curved surfaces due to the characteristics of the microfabricated structure, and it is difficult to have three-dimensionality while maintaining a smooth leveling without flowing during three-dimensional molding coating. In addition, at the same time, no deformation, discoloration, yellowing, etc. should appear during heat-hardening, and in particular, such deformation is a part in which various conditions can be easily identified with the naked eye. Development is very urgent.

As described above, in the case of the epoxy molding coating applied to conventional accessories and ornaments, the viscosity is high, the microstructure or three-dimensional shape can not be properly saved and deformation is easily generated, the present inventors have improved the weather resistance, durability, yellowing, The present invention has been completed after diligently researching to develop a molding coating of a new material that is excellent in glossiness, low viscosity type, and excellent moldability, so that a perfect molding coating can be used to a meticulous part.

In particular, the present inventors are able to present more diverse and luxurious products to modern people seeking aesthetic improvement as the living environment changes to a highly industrial society, and the workability is excellent, so that the aesthetics of high quality jewelry or interior walls can be improved. The present invention has been made with the focus on being able to economically produce and produce a coating that can be maximized.

Therefore, in the present invention, in forming a coating composition mainly composed of epoxy, unlike the conventional art, various additives such as pigments, pearls, and metal powders are mixed with a resin component mainly composed of epoxy constituting an epoxy molding coating agent, and a cured component and When appropriately using the coagulation control component at a predetermined ratio and forming and coating the cured surface of an ornament or accessory metal surface, or vertical wall surface or plate of the room, it is hardened by heat and deforms. It is an object of the present invention to provide a new coating composition that can be cured and coated with high quality with excellent physical properties without yellowing or the like.

In addition, the present invention by using a three-component component, such as the resin component, the curing component, and the coagulation control component constituting the epoxy low-viscosity molding coating agent by combining a variety of colorful accessories such as accessories, plated products of various jewelry or the surface of the wall, plate The purpose is to increase the beauty of the product economically by three-dimensional molding coating.

The present invention is a molding coating agent mainly composed of an epoxy resin containing an epoxy resin, a curing agent and a curing accelerator, 70-85% by weight of epoxy base resin, 10-20% by weight of xylene as a non-reactive diluent, and 1-5% by weight of a plasticizer. 100 parts by weight of a resin component containing 0.1-1% by weight of an antifoaming agent and 1-5% by weight of a flocculant, 50-70% by weight of a modified aliphatic amine which is a curing agent, 25-35% by weight of nonylphenol as an accelerator, and epoxy as a pre-reactive agent. 40-60 parts by weight of a curing component comprising 5-20% by weight of resin, and 80-95% by weight of modified alicyclic amine, 1-10% by weight of xylene as a non-reactive diluent, and 1-10% by weight of methylphenol as a catalyst It characterized by a low viscosity molding coating consisting of a three-component epoxy composition consisting of 0.001-0.01 parts by weight of a cohesive control component.

The coating composition of the present invention may further contain 10-30% by weight of polypropylene glycol diglycidyl ether as a reactive diluent relative to the resin component.

The molding coating agent according to the present invention is configured in a three-part type so as to mix and use the resin component, the curing component and the coagulation control component in the above proportions in the field.

Hereinafter, the present invention will be described in more detail.

The present invention is an epoxy low-viscosity molding coating that breaks the stereotype that curing coagulation is possible only at high viscosity due to the nature of the polymer resin, and mixes the resin component and the curing component to have a preliminarily flowing state at a very low viscosity state, thereby coagulating characteristics and work. It is a three-component epoxy molding coating that forms the basis of the castle and adjusts leveling, cohesiveness and workability by adding a cohesive control component appropriately formed according to the slope of the material or the characteristics of the applied wall.

The molding coating according to the present invention comprises a resin component mainly composed of an epoxy base resin, a curing component including a curing agent and a pre-reactive agent, and an aggregation controlling component for controlling the coating property by accelerating the aggregation in the final step. In the resin component for the molding coating, it is preferable to use two kinds of liquid epoxy base resins in order to have low viscosity and good flow and workability, for example, as a condensation product of epichlorohydrin and bisphenol A. It is preferable to use the one having a viscosity of 3,000-20,000 / cps at 20 ° C. More preferably, a 1: 1 mixture of such epoxy resin and 0.1-0.3% by weight of chlorine content may be used. A non-reactive diluent, a plasticizer, an antifoaming agent, a flocculant (thiso agent) and the like are mixed in the same amounts to make a resin component.

In the present invention, the curing component may be a polyoxypropyleneamine, for example, as an aliphatic modified amine as a curing agent, and nonylphenyl, for example, as a curing accelerator, and a small amount of the above-mentioned epoxy basic resin is added as a pre-reactive agent. By making a hardening component so that it may occur, compatibility and flowability become good.

On the other hand, as a coagulation-controlling component used in the final blend, triethylenetriamine or triethyltetramine may be used as the alicyclic modified amine, and the above-mentioned xylene as a non-reactive diluent, methylphenol as a catalyst, such as dimethylaminomethylphenyl, etc. This mixture can be used.

According to the present invention, the resin component, the hardening component and the coagulation control component are composed of the three-component type used in the above-mentioned mixing ratio in the field, and they are provided with various functions by controlling the mixing ratio of these components and the viscosity. It can be used by arbitrarily adjusting according to the characteristics of the application part by adjusting the application characteristics, flowability and the like.

In the low-viscosity molding coating according to the present invention, it can be considered to be divided into a hard mold and a soft mold according to the post-molding characteristics of the coating agent to be applied. For example, the composition of the hard mold is an epoxy resin and a liquid viscosity (20 ° C.) 17000 / cps, non-reactive diluent xylene, plasticizer dop, antifoaming agent byk-066, flocculant aerosil-300, the addition ratio of which may be configured as described above, but more preferably can be illustrated as follows. That is, 35-45% by weight epoxy base resin, 35-45% by weight chlorine-containing epoxy base resin, 12-20% by weight non-reactive diluent, 2.5-3.5% by weight plasticizer, 0.1-0.2% by weight defoaming agent, 2-2.5% by flocculant 100 parts by weight of the resin component consisting of% is used. In addition, the addition ratio of the composition consisting of an aliphatic modified amine, an epoxy base resin equivalent of 180 and an accelerator as a curing component may be prepared as described above, but more preferably, for example, 55-65 wt% of a modified amine, as a pre-reactive agent. 7-15% by weight of epoxy resin, 25-35% by weight of nonylphenol as the accelerator is most preferably used in a mixture of 50 parts by weight.

In addition, as the coagulation control component used in a very small amount in the present invention, a composition consisting of an alicyclic modified amine, an unreactive diluent, and a catalyst is used as the composition ratio between the above and the above, and a more preferable addition ratio is, for example, an alicyclic modification. The composition consisting of 85-90% by weight of amine, 5-7% by weight of xylene as a non-reactive diluent and 3-5% by weight of dimethylaminomethylphenyl as a catalyst is most preferably used at 0.001-0.01%. At this time, the coagulation control component is appropriately used according to the characteristics of the curved surface slope or wall, plate material of the accessory or jewelry material.

On the other hand, similarly to the above, when looking at the composition of the soft type, the epoxy base resin as a resin component, the viscosity of the liquid state (20 ℃) 17000 / cps, reactive diluent pg-207, non-reactive diluent xylene, plasticizer dbp, defoamer byk -066, flocculant Arosil-300 can be used, the addition ratio is, for example, 75-85% by weight epoxy base resin, 13-20% by weight non-reactive diluent, 1-1.5% by weight plasticizer, 0.1-0.2% by weight defoamer, 100 parts by weight of a resin component consisting of 1.5-2% by weight of a flocculant is used, and more preferably, 10-30% by weight of a reactive diluent such as polypropylene glycol diglycidyl ether is added to produce a resin component. Very good to save. The cured component and the coagulation controlling component can be used in the same manner as in the above and the hard type.

When explaining the manufacturing process for the hard and soft three-component molding coating agent as an example can be illustrated as follows.

[Hard-type coating agent composition process]

The non-reactive diluent is added to the epoxy base resin and mixed, followed by low speed mixing by adding a flocculant, compression milling using a mill roller, and then low speed mixing by adding a non-reactive diluent, a plasticizer, an antifoaming agent, and a flocculant. At this time, the milling compression must maintain a constant density due to the molecular structure of the flocculant so as to control the function of the flocculation control component to be mixed later. To do this, it is necessary to accurately adjust the basic resin viscosity according to the relative temperature.

In the hard coating composition, epoxy base resins are epichlorohydrin and bisphenol-A condensation products. For example, it is more preferable to use two kinds of A and B, which are ordinary and combustion-containing. As a viscosity (20 ℃) 18000-20000 / cps, equivalent 195, specific gravity (20 ℃) 1.7, refractive index (20 ℃) 1.05720, B is a liquid transparent resin containing 0.15% of chlorine content. ) 7000-8000 / cps, equivalent 190, specific gravity (20 ° C.) 1.5, refractive index 1.5417 can be preferably used.

As a non-reactive diluent, which is a solvent, xylene is used, which is suitable for use as the non-reactive diluent of the present invention because of its favorable affinity between the epoxy base resin and silicon dioxide and its low volatility. In addition, for example, dibutyl phthalate may be used as the plasticizer, polysiloxane may be used as the antifoaming agent, and silicon dioxide may be preferably used as the curing agent.

However, in some cases, a reactive diluent such as polypropylene glycol diglycidyl ether having a reactivity toward the epoxy-based monomolecule may be further used in the same amount as the non-reactive diluent.

To the aliphatic modified amine as the curing component, the same epoxy base resin of the same type as the above is added as a pre-reactant and mixed by adding an accelerator. At this time, in order to promote exothermic reaction, preheating should be performed. The mixing here is completed by stopping the exothermic reaction when it reaches a high point and pulling it back at room temperature (20 ° C.) for about 12 hours.

In the composition of the resin component, in the low viscosity characteristic, the accelerated curing state is provided in a semi-preliminary state, that is, a state in which the coagulation control component is not added is maintained even after the resin component and the cured component are respectively mixed or mixed. This is to make it easy to mix various mixtures (pigments, pearls, metal powders) and other kinds of accessories that can increase the beauty of the resin component in the state where the resin component and the curing component flow. For example, if the surface has a low degree of inclination but strong cohesiveness, the smoothness is low, and in detail, the three-dimensional sense cannot be properly utilized. Also. The resin component and the cured component are in the preliminary state of coagulation control, so that the flow control can be freely controlled by using the coagulation control component in the work. This is an alicyclic ring containing aerosil-300 and silicon dioxide in the coagulation control component. This is because the rapid reaction with the group-modified amine causes the adsorption phenomenon to exhibit strong curability. The coating agent of the present invention obtained as described above has a hydrogen bond on the surface of the silicon dioxide of the coagulant, thereby increasing the coagulation effect (thiso tropic) during epoxy curing, and is adsorbed due to the chemical adsorption phenomenon by the addition of silicon dioxide. Aggregation occurs due to the increase in energy.

The coagulation control component is formulated by combining a modified alicyclic amine, a non-reactive diluent, and a catalyst in a conventional manner. As the coagulation control component in the present invention, for example, an alicyclic primary amine may be preferably diethylenetriamine. In particular, as the non-reactive diluent, xylene, as described above, is used as a catalyst, for example, dimethylaminomethylphenol. Can be used.

[Composition process of soft coating agent]

The non-reactive diluent is added to the epoxy base resin and mixed, followed by low speed mixing with the addition of the flocculant, followed by compression milling using a mill roller, the non-reactive diluent mixed, followed by the addition of the plasticizer, the antifoaming agent and the flocculant, and the low speed mixing . At this time, the nature of the molecular structure of the flocculant, milling compression must maintain a constant density to be able to control the function of the cohesive adjustment component mixed later. To do this, it is necessary to accurately adjust the basic resin viscosity according to the relative temperature.

The epoxy base resin used in the present invention may be a condensation product of epichlorohydrin and bisphenol A as described above, but may be used by mixing a small amount of isoprene glycidyl ether in addition to the epoxy base resin. However, it is advantageous to use the epoxy resin in two kinds, one containing no chlorine and the other containing the same as the hard type described above.

In addition to the non-reactive diluent, a monomolecular polypropylene glycol diglycidyl having an epoxy group can be used as an reactive diluent by mixing about 10-30% with the epoxy base resin.

The soft coating is also generally the same as the hard type, but the soft type, unlike the hard type, exhibits soft hardening flocculation characteristics, so it is preferable to use it where elasticity is required.

In addition, all non-reactive diluents, plasticizers, antifoaming agents and flocculants are used in the same manner as the hard type.

In addition to the resin component in the present invention, the hardening component and the coagulation control component may be used in the same manner as the hard type and the soft type. As the curing component, polyoxypropyleneamine may be preferably used as the aliphatic modified amine, and as the pre-reactive agent, It is preferable to use only one type of A resin, which is a condensation product of epichlorohydrin and bisphenol-A in physical properties, and a nonylphenol having no molar number as an accelerator. That is, two kinds of A and B are different in the epoxy base resin thus prepared, but the curing component may be used as any one of A and B.

As described above, according to the present invention, when each of the components in the resin component, the curing component and the coagulation control component is excessive or smaller than the content, the composition of the composition may not be made or properties may not be obtained and mechanical properties may not be obtained.

Meanwhile, in the molding coating agent of the present invention, as described above, the composition is applied in the usual manner and applied to the plated surface of the accessory ornament or the wall plate or the appropriate molding surface, and the additives such as gold powder, silver powder, and pearl are added to 100% by weight of the resin component. 40-60% by weight of the cured component is added, followed by molding coating by adding 0.001-0.01% by weight of the coagulation control component according to the surface slope or surface characteristics and the like, followed by heat curing at 70-90 ° C. for 30 minutes-2 hours. Complete However, in the case of a wall or plate that is not three-dimensional, it is sufficient to natural harden at 20 ° C. for 8-12 hours.

In the present invention, a pigment may be additionally added to the resin component. As the pigment, an inorganic pigment or an organic pigment having high heat resistance and strong weather resistance may be used in an amount of 1-5 parts by weight based on 100 parts by weight of the epoxy resin composition. . Inorganic pigments can be used as 0.2-0.4μ size, even larger than 25μ size. Specific examples include chromium (green), cadmium (chdmium) (red) titanium dioxide (silicates), ferrocyanide (red), sulfide (shelfyde), oxides (dxides) and silgates Carbon black can be used, which can be changed by applying coprecipitation with various metal salts.

Organic pigments may be used a variety of conventional, including phthalocyaanine-based, in particular, can be used alone or mixed with inorganic pigments quinacridine (quinacridine) pigments. The pigment is mixed with the epoxy base resin in the planned high content in consideration of the covering force, and pressed and milled. Then, toner is added to the epoxy resin composition by adding 1-5 parts by weight of the inorganic or organic pigment color base milled to 100 parts by weight of the resin. It can also be used. Also, gold here. Metal powders such as silver may be used, and various color coated PVC or PE powders may be mixed.

As described above, when forming a coating coating on the surface, that is, accessories, ornaments, or the wall to be applied to the three-component coating composition according to the present invention to obtain a beautiful surface coating effect with excellent low viscosity characteristics and workability without blurring or blurring It can be very useful for coating high quality ornaments or walls with a beautiful appearance.
