Abstract
The invention discloses an infrared reflection color paste, a preparation method and an infrared reflection electrophoretic paint and application thereof. The infrared reflection color paste comprises 10-70 parts of infrared reflection pigment; 5-12 parts of dispersing agent; 40-70 parts of polar solvent; the dispersing agent is maleic anhydride-acrylic acid copolymer dispersing agent, polyether dispersing agent, polyurethane oil-water dual-purpose dispersing agent, hydrophobic modified styrene-acrylic acid terpolymer dispersing agent or modified polyacrylic resin dispersing agent. Before use, the aluminum profile paint film obtained after anode or cathode electrophoresis can provide weather resistance better than the traditional electrophoresis paint film, and can reduce the surface temperature of the aluminum profile by about 15 ℃, thereby playing a role in energy conservation and emission reduction, responding to the call of low carbon, green and environment protection, and achieving the general trend pursued worldwide.
Description
Technical Field
The invention relates to the field of paint, in particular to infrared reflection color paste, a preparation method and infrared reflection electrophoretic paint and application thereof.
Background
Aluminum alloy doors and windows, aluminum curtain walls and aluminum veneers are almost one of the necessary building materials for our modern buildings. Because the heat conductivity coefficient of the aluminum alloy material is very high, in order to reduce the heat dissipation of indoor heating air through the aluminum alloy doors and windows to the outside in the north and increase the energy consumption, a rubber strip with low heat conductivity coefficient is added between the aluminum alloy after the surface treatment of fluorocarbon spraying, powder spraying or anodic oxidation electrophoresis on the surface of the finished aluminum alloy by a special heat insulation bridge-cut-off mode during the assembly of a door and window factory, so that the indoor heating air is prevented from leaking through the aluminum alloy doors and windows, and the effects of energy conservation and emission reduction are achieved.
In the south, since the summer weather is hot and the time period is long, the sunlight intensity is high and the sunlight time is long, and the indoor temperature must be reduced by using the air conditioner cool air or the fan for a long time. The infrared absorption value for the temperature rise in the natural sunlight is very high, and after a large amount of external infrared rays are absorbed, the infrared absorption value can be led into a room through the aluminum alloy doors and windows, the aluminum curtain walls and the aluminum veneers in any surface treatment mode, so that the indoor temperature is increased or the working time of an air conditioner compressor is increased, and the power consumption is increased.
With the continuous deep concept of low carbon for the whole people, lower carbon emission is pursued no matter daily life needs or industrial manufacturing is pursued worldwide, and the purposes of energy conservation, emission reduction and environmental protection are achieved. Therefore, with respect to the above technology, in the current practical application process of aluminum alloy building materials, because the energy absorbed by the aluminum alloy is more, the energy loss is more serious along with conduction and emission into the environment, and further improvement is urgently needed.

50-60 parts of polar solvent.
The electrophoretic paint is water paint, most of the resin is weak alkaline or weak acid, and the electrophoretic paint has high requirement on pigment. In particular, the physical properties of different pigments, such as relative density, acid-base, polarity, crystal shape and the like, are different, and in the manufacturing process of the electrophoretic coating, the pigments are often dispersed in color paste temporarily even if strongly stirred due to large difference of the physical properties, so that the problems of precipitation, flooding and the like are often caused after long-time storage. Thus, compatibility of the same type of pigment is more difficult to match than fluorocarbon spray or powder spray relative to electrophoresis.
In recent years, along with energy conservation and emission reduction, improvements in reducing carbon emission relate to aspects of life. The most used aluminum alloys are building materials. In order to reduce the problem of large carbon emissions due to the problem of large thermal conductivity of aluminum profiles themselves, the inventors have desired to apply infrared reflective pigments to aluminum profiles. An infrared reflective pigment is a pigment that reflects light in the visible region, absorbs light in the ultraviolet region, reflects light in the infrared region, or a combination of any of the three. Therefore, the material has certain color, even darker color, and can reflect a part of infrared light, reduce heat accumulation and make the surface of the material not easy to absorb heat. If the infrared reflection pigment can be successfully applied to the aluminum profile, external heat is not easy to be led into a room through the aluminum alloy door and window to reduce power consumption when the weather is hot, and the effects of energy conservation and emission reduction are achieved.
Currently, aluminum alloy coating processes include fluorocarbon spraying, powder spraying and electrophoretic coating, wherein fluorocarbon spraying and powder spraying are performed by spraying a spray gun against a workpiece, and if the workpiece is to be fully sprayed in place, the workpiece itself is preferably a plane. However, aluminum materials used in daily life are often not flat surfaces, but a plurality of grooves and bending places exist, and the special-shaped material workpiece is not sprayed in place in the places such as grooves and bending of the workpiece for fluorocarbon spraying and powder spraying. In the electrophoretic coating, the workpiece is immersed in the electrophoretic bath solution, and all parts of the workpiece can be contacted with the electrophoretic bath solution, so that the special-shaped aluminum profile can be coated in place most by the electrophoretic coating mode.
By combining the trend of energy conservation and emission reduction with the problems existing in the prior art, the inventor researches to add the infrared reflection pigment into the electrophoretic paint, and evenly coat the infrared reflection pigment on the surface of the aluminum profile in an electrophoretic manner, so as to achieve the purposes of energy reflection, energy conservation and emission reduction. However, in practice, it is found that when the infrared reflective pigment is directly added into the electrophoretic paint, the problem of chemical and electrochemical compatibility can be caused by the strong hydrophilicity of most dispersing agents or the mixing of the infrared reflective pigment and the electrophoretic paint, so that the coulomb conductivity is inconsistent, the problems of film coating speed, paint film surface flatness and paint film gloss hand feeling during electrophoresis can be caused, and finally, more surface defects can be generated. For example, the problems of poor weather resistance, poor binding fastness, uneven paint film coating, change in gloss, flow marks or a series of complexities such as lightening and roughening of the color of the infrared reflective pigment after passing through anion-cation bed ion exchange, result in difficulty in applying the infrared reflective pigment, especially the matt/gloss paint, to the aluminum material by the electrophoretic coating method.
Through continuous efforts and intensive researches of the inventor, finally, the infrared reflection color paste is discovered, wherein the color paste is composed of infrared reflection pigment, a specific selected dispersing agent type and a polar solvent in a specific proportion, and the infrared reflection color paste, anode/cathode electrophoretic paint and water are prepared into an electrophoretic bath solution before use. The kind and the content of dispersing agent are great to the influence of electrophoresis lacquer, in order to guarantee the thick and the quality of film, according to the polarity of mill base system in this application, select above-mentioned kind of dispersing agent to combine the ratio that this application set for again, the electrophoresis film thickness that obtains after the positive pole/negative pole electrophoresis is moderate and even, more weather-proof than traditional electrophoresis color paint, and can reduce aluminium alloy surface temperature around 15 ℃, thereby play energy saving and emission reduction effect, respond to the call of low carbon green, reach the big trend that pursues worldwide.
Preferably, the polar solvent is deionized water or an alcohol ether polar solvent with a boiling point of 120-200 ℃ for oil-water dual purposes, and the alcohol ether polar solvent with a boiling point of 120-200 ℃ for oil-water dual purposes is further selected.
The application of deionized water to electrophoretic paints is certainly a less costly option. In addition, the color paste can be prepared from a medium-high boiling point solvent, the dispersion uniformity of the infrared reflection pigment in the color paste is extremely important, and the medium-high boiling point alcohol ether solvent is not easy to volatilize in the grinding process, so that the reduction degree of the viscosity of the color paste in the grinding process can be stably maintained, the color paste concentration and the color paste stability which are consistent as much as possible are maintained, the infrared reflection pigment is fully wetted, the infrared reflection pigment and the components in the color paste are better compatible, a paint film obtained after electrophoresis is more uniform, the film forming quality is good, the stability of an electrophoresis paint film is improved, the surface roughness of the paint film is lower, and the hand feeling is improved.
More preferably, the alcohol ether polar solvent is ethylene glycol butyl ether, methyl tertiary butyl ether and polyethylene glycol dimethyl ether according to the mass ratio of 1: (0.2-0.5): (0.1-0.4) and is compounded.
Besides better compatibility of all components in the color paste, the polar solvent prepared by the components in proportion can also stabilize the electrophoresis tank liquor. The stability of the bath solution of the electrophoretic paint means that the bath solution is not deteriorated after long-term use under the specified process condition, and the performance of the coating film obtained by the electrophoretic paint is qualified. The infrared reflection color paste, the electrophoretic varnish and water are prepared into the electrophoretic bath liquid before electrophoresis, and at the moment, the compatibility between the infrared reflection color paste and the electrophoretic varnish is particularly important for the stability of the electrophoretic bath liquid. The polar color paste formed by the combination of the special proportions enables the infrared reflection color paste to be compatible with the electrophoretic varnish and good in compatibility, so that the prepared electrophoretic bath solution is good in stability, and a paint film after electrophoresis is stable in state and easy to process and produce in a large scale.
Preferably, the infrared reflection color paste further comprises 10-30 parts of grinding resin.
More preferably, the grinding resin is one or more of acrylic resin, polyurethane and polyester.
Most preferably, in the anodic electrophoretic paint, the grinding resin is a hydroxy acrylic resin.
In the color paste system, compared with acrylic resin, the hydroxyl acrylic resin has the advantages that the solubility of the resin in water is increased due to the addition of polar groups, meanwhile, the viscosity of a resin solution can be adjusted, the field operation stability of the electrophoretic paint is improved, the coloring capability of the infrared reflection pigment is improved, the color paste is compatible with paint liquid in the working process of a bath solution, and the purposes of improving the leveling property and the appearance of a coating film are achieved.
Preferably, the infrared reflection color paste further comprises 0.3-1 part of an auxiliary agent, wherein in the anode electrophoretic paint, the auxiliary agent is an organic amine neutralizer; in the cathode electrophoretic paint, the auxiliary agent is an organic acid neutralizer.
More preferably, the organic amine neutralizer is dimethylethanolamine, triethanolamine or 2-amino-2-methyl-1-propanol, and still further, the organic amine neutralizer is prepared from 2-amino-2-methyl-1-propanol and water in a mass ratio of 1: (0-0.05) and is compounded.
The neutralizing agent prepared by the method plays a role in neutralization, and is matched with the dispersing agent of the application to greatly improve the dispersing effect of the pigment, and accordingly, the using amount of the dispersing agent can be reduced. In addition, if grinding resin exists in the color paste, the mass ratio of the 2-amino-2-methyl-1-propanol to the water is 1: the auxiliary agent compounded in (0-0.05) is matched with the grinding resin, so that the grinding color paste is stabilized at a moderate pH value in the grinding process, the re-coagulation of the pigment after paint preparation is reduced, the pH value of the paint liquid is close to that of the paint liquid, the compatibility and stability of the paint liquid are improved, the uniformity of an electrophoretic paint film is improved, and the formed paint film has better hand feeling; in addition, paint films at the positions of bending and grooves of the aluminum material are more uniform, so that the aluminum material is not easy to oxidize when contacting with outside air, and the aluminum material is well protected.
In a second aspect, the present application provides a method for preparing an infrared reflection color paste, wherein the polar solvent and the dispersant are uniformly dispersed, then the infrared reflection pigment is added in a high-speed stirring state with a rotation speed of 1200rpm or more, the high-speed dispersion and the uniform stirring are performed, and the infrared reflection color paste is obtained after grinding; when the infrared reflection color paste contains grinding resin and/or auxiliary agent, the grinding resin and/or auxiliary agent and the polar solvent are dispersed together.
In a third aspect, the present application provides an infrared reflection electrophoretic paint, which is prepared by mixing the above-mentioned infrared reflection color paste, anode electrophoretic paint and water to obtain an infrared reflection anode electrophoretic paint with a solid content of 10-33%; or the prepared infrared reflection color paste, the cathode electrophoresis paint and water are mixed into the infrared reflection cathode electrophoresis paint with the solid content of 10-33 percent.
Preferably, the anode or cathode electrophoretic coating is selected from one or more of polybutadiene, polyurethane, polyester, acrylic acid and epoxy resin.
In order to match the infrared reflection pigment, the resins are specifically selected as the cathode electrophoretic coating, so that the temperature reduction degree of the surface of the paint film after electrophoresis is further improved, and the weather resistance of the paint film is also improved.
When the infrared reflection anode or cathode electrophoretic paint is prepared, various color pastes can be added into the raw paint in advance, after full stirring, the anode electrophoretic paint is diluted with water to adjust to solid matters required by the optimal work of the infrared reflection pigments with different colors, or the tank liquor can be diluted according to a proper proportion, and various color pastes are added into the paint liquor, so that the color can be adjusted more easily. The color paste is better fused with the anode electrophoretic paint in the mixing mode, precipitation is not easy to generate, the infrared reflection color paste is more uniformly electrophoresed on the aluminum alloy in the electrophoresis process, and the obtained coating film is firmer and has stronger weather resistance.
Preferably, the anodic electrophoretic coating is a thermosetting acrylic resin.
The thermosetting acrylic resin has certain functional groups in the structure, and the functional groups such as amino resin, epoxy resin, polyurethane and the like added during the paint preparation react to form a network structure, so that the thermosetting acrylic resin has relatively low molecular weight, good compatibility, throwing power, excellent fullness, luster and hardness, and does not change color or yellow after baking at high temperature.
Preferably, the molecular weight of the resin used for the anode electrophoretic coating and the cathode electrophoretic coating is 5000-100000.
The molecular weight of the resin is large, the steric hindrance is large, the viscosity is increased, and the electrophoresis process is not facilitated; but the small molecular weight affects the corrosion resistance of the paint film. Practice proves that for certain types of resin, the resin has good water solubility and good film gloss when the relative molecular mass is smaller, but the formed film has poor weather resistance. On the contrary, when the relative molecular mass is large, the water solubility of the resin is poor, but the coating film is flat and smooth, and has good corrosion resistance, electroosmosis, throwing power and physical property. Therefore, on the premise of ensuring that the resin has good water solubility, the relative molecular mass of the water-soluble resin is made to be larger as much as possible. In the infrared reflection electrophoretic paint system, the molecular weight of the resin in the electrophoretic paint is controlled within the range of 5000-100000, so that the electrophoretic process is not easy to influence, and the formed paint film has good hand feeling.
