Description
Technical Field
The invention relates to a color correction auxiliary material for paint, in particular to an ultraviolet light curing transparent color correction mother solution and a preparation method and application thereof.
Background
In order to make furniture appear more beautiful and diversified colors in the manufacturing process of the furniture, the paint is often required to be mixed with colors, and different coating construction processes are combined to make the furniture into a designed effect. The color can be divided into transparent color and solid color, the texture of the base material can be seen after the color of the panel is changed after the coating, the solid color coating is the coating which covers the texture and the color of the base material and only shows the color of the coating, and the furniture coated with the solid color is usually pure white, pure black, pure blue and the like.
The transparent furniture template is often made by bottom coloring, surface retouching or bottom coloring plus surface retouching. The bottom coloring is to perform color mixing and coating on the first coating coated on the base material, and the surface color finishing is to perform color mixing and coating on the non-final finish. Since multiple times of grinding and multiple coating are often involved after the bottom coloring, the process easily causes uneven color of the board surface, and therefore, the problem needs to be solved by surface color modification during the coating of the finish paint.
UV curing refers to a process of converting a substance from a low molecule to a high molecule under irradiation of ultraviolet light, and is different from ordinary thermal curing, natural curing, crosslinking agent curing, and the like. The curing mechanism is as follows: the light irradiation makes the photoinitiator crack into free radicals or anions and cations, further initiates the monomer containing active groups to carry out polymerization reaction, and the monomer is polymerized into an insoluble and infusible solid coating. Compared with the traditional curing technology, the UV curing technology saves energy, has high curing speed and good coating performance, is suitable for large-scale industrial production, and simultaneously, the UV curing material does not contain or only contains a small amount of Volatile Organic Compounds (VOCs) in the curing process, and is known as 'green technology'. Typical light sources used in UV curing systems are: medium and high pressure mercury lamps, metal halide lamps, electrodeless lamps, xenon lamps and UV-LED lamps.
Because the UV coating applying the UV curing technology has the advantages, the UV coating is in the gold development period along with the rising of the labor cost of enterprises, the stricter environmental protection requirement and the upgrade of national industry in recent years. In the process of replacing solvent-based paint with UV paint, due to the difference of base materials and coating processes, the market puts forward demands on more varieties of UV paint, and the UV color correction liquid is one of the UV color correction liquids.
The UV color correction liquid consists of a color concentrate and an ultraviolet light curing transparent color correction mother liquid, and when the ratio of the color concentrate to the ultraviolet light curing transparent color correction mother liquid reaches 0.25:1, about 10% of solvent exists in the UV color correction liquid due to the fact that the color concentrate contains more than 50% of solvent. The UV roller coating production line is constructed continuously, the UV color correction liquid enters the photo-curing machine for curing about 3 seconds after roller coating is finished, the solvent in the UV color correction liquid can not be volatilized, the film forming process of the UV color correction liquid is directly influenced by the existence of a large amount of solvent, and the adhesive force of the UV color correction on a bottom paint film is further influenced.
Cationic photoinitiators are a very important class of photoinitiators, and when absorbing light energy to an excited state, molecules undergo a photolytic reaction to generate a super acid, i.e., a super proton acid or a lewis acid, thereby initiating cationic polymerization of cationic oligomers and reactive diluents. The cationic photocuring active intermediate super acid is chemically stable, and the positive charges cannot be coupled and disappear, and new super acid is generated when the chain is terminated, so that after the illumination is stopped, the polymerization crosslinking can be continuously initiated to perform post curing. The free radical photo-curing loses initiation activity because free radicals are easy to couple, and once the light irradiation is stopped, the photo-curing is stopped immediately, and the post-curing phenomenon does not occur.
The Chinese patent application CN201110424731.5 discloses an ultraviolet-curing roller-coating color-modifying finish paint, which comprises the following components in parts by weight: 35-50 parts of epoxy acrylate, polyester acrylate or a mixture thereof, 30-42 parts of a reactive diluent, 0.2-0.5 part of a defoaming agent, 0.5-1 part of a functional additive, 0.1-0.3 part of a leveling agent, 8-13 parts of a filler and 9-12 parts of a photoinitiator; the invention adds dye into the conventional ultraviolet light curing coating to prepare the color-modifying finishing coat, 15 percent of dye can be added at most at one time, and more dye needs to be added when the color plate needs darker color; if the required color is achieved by one-time construction when the additive amount of the dye is increased to be more than 15% and reaches 25% or even higher, the UV color-modifying finishing paint is affected by the excessively high additive amount of the dye, so that the adhesion problem is caused, and therefore if the color-modifying finishing paint is adopted, the additive amount of the dye is required to be lower than 15%, and the required color is achieved through multiple constructions.
Chinese patent CN201310572563.3 discloses a free radical-cation hybrid photocureable coating and a preparation method and a use method thereof. The components comprise, by weight, 10-60% of photosensitive organic resin, 5-40% of hybrid photosensitive monomer, 10-50% of active solvent, 2-4% of mixed photoinitiator and 0.1-0.2% of auxiliary agent; the preparation method comprises the following steps: placing photosensitive organic resin in a container, adding the mixed photosensitive monomer to prepare a mixed solution; dissolving the mixed photoinitiator in an active solvent, adding the mixed photoinitiator and the auxiliary agent into the mixed solution, and uniformly mixing. The using method comprises the following steps: coating the free radical-cation hybrid photocureable coating on the surface of a metal matrix, preserving heat at 60 +/-5 ℃, and irradiating under ultraviolet light. The invention solves the problem of poor adhesion of the paint film on the surface of the metal substrate by utilizing the characteristic that the cationic photoinitiator initiates the cured paint film to shrink little. Although the invention adopts the dual curing of free radicals and cations, the instant reaction of the photocureable coating under the condition of ultraviolet irradiation is not controlled, when the coating contacts ultraviolet light, various components in the coating are instantly polymerized, and the post-curing of a cationic photoinitiator can not really play a role, therefore, 25 percent of color concentrate is added into the invention to prepare the UV color correction liquid, the color correction liquid is instantly polymerized under the condition of ultraviolet irradiation, but a large amount of solvent is still remained at the moment introduced due to the addition of the color concentrate, and the residual solvent directly causes the serious adhesive force problem of the color correction liquid.
Chinese invention patent CN201610822186.8 discloses a free radical/cation dual-curing UV ink with small curing shrinkage and a preparation method thereof. The photo-curing principle of the invention is similar to that of the Chinese patent CN201310572563.3, and the photo-curing ink is prepared by adding pigment on the basis of CN201310572563.3 and grinding. Firstly, the pigment and the color concentrate dye are two types of substances, and the influence of the pigment on photocuring is that the covering property of the pigment influences the penetration of ultraviolet light on a paint film, so that the UV ink curing is influenced. In addition, the pigment powder is directly added into the ink base material to prepare the colored ink through grinding, and no solvent is brought into a system, so that the influence of the solvent on the adhesion of a photocureable paint film does not exist in the invention. If the pigment in the invention is replaced by adding 25% of dye or color concentrate, the prepared paint film has the adhesion problem due to the influence of a large amount of solvent in the dye or color concentrate.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides the ultraviolet curing transparent color-modifying mother liquor and the preparation method thereof, wherein the ultraviolet curing transparent color-modifying mother liquor has good adhesive force when a large amount of color concentrates are added, 25 wt% of the color concentrates can be added at one time, and the construction efficiency is obviously improved;
the invention also aims to provide the application of the ultraviolet curing transparent color-modifying mother liquor in preparing the UV color-modifying liquor.
When the color repairing mother liquor prepared by the method is used for color matching, the color concentrate can be added by 25 percent once, and when transparent deep color coating is carried out, the final color coating effect can be achieved through one color repairing process, so that the construction efficiency is greatly improved
Because the reaction rate of free radical polymerization is extremely fast, the initiator generates free radicals immediately after receiving ultraviolet irradiation, and the fastest chain growth can be completed within 0.05 s-0.1 s, therefore, the conventional ultraviolet curing coating immediately reacts at the moment of contacting with ultraviolet light, and the conversion rate rapidly rises to more than 95 percent. For the UV color correction liquid added with the color concentrate, the color concentrate contains more than 50% of solvent, so the fast reaction rate causes that the polymerization reaction is completed before the solvent is volatilized, and the film forming process is equivalent to the small molecule polymerization and then the large molecule accumulation. And because the macromolecular polymer has larger molecular weight and can not move freely, and the glass transition temperature is higher, substances with larger molecular weight are more difficult to form close packing and fuse with other substances, so that the conventional UV color repair liquid can not form a firmly combined paint film at last and can not fuse with a bottom paint film, and the adhesion is poor.
According to the invention, the ultraviolet light absorbent and the bridging agent are added into the ultraviolet light curing transparent color correction mother liquor, and the double curing of free radicals/cations is adopted, so that the problem of poor adhesion of the UV color correction liquor when a large amount of color concentrates are added into the ultraviolet light curing color correction mother liquor is solved.
The ultraviolet absorbent can absorb part of ultraviolet light and convert the ultraviolet light into heat energy, so that the photoinitiator is protected, free radicals are gradually generated by the initiator, polymerization is gradually initiated, and the conversion rate is gradually increased. Meanwhile, the heat energy released by the ultraviolet absorber after absorbing ultraviolet light can promote the solvent to volatilize. For the color correction liquid added with the color correction in the ultraviolet curing transparent color correction mother liquid, the film forming process comprises the steps of gradually polymerizing the micromolecule oligomer or monomer while volatilizing the solvent, and simultaneously accumulating the micromolecule oligomer or monomer and the macromolecular polymer. After the solvent is volatilized, the small molecular oligomers or monomers which are closely packed can be initiated to continue the reaction due to the post-curing effect of the cationic polymerization. The method enables the curing process of the UV color correction liquid paint film to be changed from the process of polymerization and then accumulation of the conventional UV color correction liquid to the process of polymerization and accumulation at the same time, so that the polymer in the paint film is changed from a physical accumulation state to chemical crosslinking, and finally the paint film with good adhesive force is formed.
When the UV color correction liquid is cured, due to reaction heat release and ultraviolet irradiation, the temperature of a paint film rises, and the temperature rise can soften the bottom paint film. At the moment, the super acid generated after the bridging agent and the cationic initiator added into the ultraviolet curing transparent color correction mother solution are photolyzed can 'break' the surface of the bottom paint film contacted with the UV color correction liquid to a certain degree, so that the UV color correction liquid and the bottom paint film are further physically fused. Because the physical fusion needs a certain time, the UV color correction liquid is gradually polymerized into a film after the ultraviolet light absorber is added, so that the ultraviolet light absorber, the free radical/cation dual curing agent and the bridging agent act together to enable the oligomer or monomer in the UV color correction liquid and the oligomer or monomer containing double bonds remained in the bottom paint film to continuously generate polymerization reaction after the physical fusion, the two paint films are combined into a whole, and the adhesive force of the UV color correction liquid on the bottom paint film is further improved.

The formula of the ultraviolet curing transparent color-modifying mother liquor is shown in a table 1 a:
TABLE 1a UV-curable clear color-modifying mother liquor formulation
The preparation method comprises the following steps: 44.4 parts of urethane acrylate oligomer, 23.0 parts of epoxy acrylate oligomer, 3.0 parts of epoxy resin, 20.0 parts of active monomer, 2.0 parts of bridging agent, 0.1 part of ultraviolet absorbent, 3.5 parts of free radical photoinitiator, 2.5 parts of cationic photoinitiator, 0.2 part of defoaming agent, 0.5 part of flatting agent and 0.8 part of wetting agent by weight, stirring at medium speed (700 and 1000 revolutions per minute) for 20min to prepare the ultraviolet curing transparent retouching mother liquor X-1, and measuring the viscosity to be 500cp by a Brookfield rotational viscometer at 25 ℃.

The color correction mother liquor (X-1) is adopted to adjust color according to color requirements, 20 parts of color concentrate can be added into 100 parts of color correction mother liquor to adjust color, the mixture is stirred for 8min at medium speed, and filtered and discharged through 240-mesh filter cloth to prepare the UV color correction liquor (X-1S).
Selecting a black walnut board, roll-coating UV transparent putty H4N001 and UV transparent primer H4D001 from 1 channel of Jiabaoli company to the board leveling, and roll-coating UV color-correcting liquid on the basis. The UV color correction fluid is subjected to photocuring after roll coating construction, and the curing and drying condition of the paint surface can be tested by a finger touch method (the grade of the drying condition of the paint film surface tested by the finger touch method indicates that 0 grade is finger-pressing dry, namely a finger presses the paint film surface with force, no fingerprint remains in the paint film, 1 grade is finger-pressing dry, namely the finger touches the paint film surface with light, if the paint film surface feels sticky, but no paint is stuck on the finger, 2 grade is not dry, the paint film surface is touched with the finger with light, so that the paint can be stuck on the finger), the paint film adhesion condition is tested by a GB9286 marking method (the grade of the adhesion tested by the marking method indicates that 0 grade is that the edge of a cut is completely smooth, the edge of a grid does not peel off, 1 grade is that small pieces are peeled off at the intersection of the cut, the actual damage in the marking area is not more than 5 percent, 2 grade is that the edge and/or the intersection of the cut is peeled off, the area is more than 15 percent, and grade 3 grade is that the cut edge is partially peeled off or a whole piece is peeled off along the edge of the cut, and/or some of the cells are exfoliated in whole pieces, the area exfoliated exceeding 15% but less than 35%; grade 4 is that the edge of the cut is largely peeled off and/or some squares are partially or completely peeled off, and the area of the cut is more than 35% of the area of the ruled area but not more than 65%; grade 5 is any degree of exfoliation that cannot be measured with a standard of even grade 4).
The highest proportion of the added color concentrates of the roller-coating color-modifying finishing paint of CN201110424731.5 is 15 percent, and is basically the highest proportion of the added color concentrates of the conventional color-modifying finishing paint, so that the results of the comparative test of the roller-coating color-modifying finishing paint used as a reference sample and the coating film of the UV color-modifying liquid (X-1S) in the embodiment are shown in a table 1 c.
TABLE 1c comparative test results of the coating films of the reference and the UV color correction fluid (X-1S) of this example
From Table 1c, it can be seen that the surface drying condition (0 grade better than 1 grade) and the adhesion condition (0 grade better than 3 grade) of the sample (X-1S) are both significantly better than the reference sample when the same proportion of the color concentrates is added to the reference sample.
In the embodiment, the ultraviolet light absorbent and the bridging agent are added into the ultraviolet light curing transparent color modifying mother liquor, and the problem of poor adhesion of the UV color modifying liquor when a large amount of color concentrates are added into the ultraviolet light curing color modifying mother liquor is solved by adopting the free radical/cation dual curing.
The ultraviolet absorbent can absorb part of ultraviolet light and convert the ultraviolet light into heat energy, so that the photoinitiator is protected, free radicals are gradually generated by the initiator, polymerization is gradually initiated, and the conversion rate is gradually increased. Meanwhile, the heat energy released by the ultraviolet absorber after absorbing ultraviolet light can promote the solvent to volatilize. For the color correction liquid added with the color correction in the ultraviolet curing transparent color correction mother liquid of this embodiment, the film forming process includes that the small molecular oligomer or monomer gradually polymerizes while the solvent volatilizes, and the small molecular oligomer or monomer and the macromolecular polymer are simultaneously accumulated. After the solvent is volatilized, the small molecular oligomers or monomers which are closely packed can be initiated to continue the reaction due to the post-curing effect of the cationic polymerization. In the embodiment, the UV color correction liquid paint film curing process is changed from the process of first polymerizing and then stacking the conventional UV color correction liquid to the process of polymerizing and stacking simultaneously, so that the polymer in the paint film is changed from a physical stacking state to chemical crosslinking, and finally the paint film with better adhesive force is formed.
When the UV color correction liquid is cured, due to reaction heat release and ultraviolet irradiation, the temperature of a paint film rises, and the temperature rise can soften the bottom paint film. At this time, in this embodiment, the super acid generated after the bridging agent and the cationic initiator added to the ultraviolet-curable transparent color-modifying mother liquid are photolyzed may "damage" the surface of the bottom paint film in contact with the UV color-modifying liquid to a certain extent, so that the UV color-modifying liquid and the bottom paint film are further physically fused. Because the physical fusion needs a certain time, the UV color correction liquid is gradually polymerized into a film after the ultraviolet light absorber is added, so that the ultraviolet light absorber, the free radical/cation dual curing agent and the bridging agent act together to enable the oligomer or monomer in the UV color correction liquid and the oligomer or monomer containing double bonds remained in the bottom paint film to continuously generate polymerization reaction after the physical fusion, the two paint films are combined into a whole, and the adhesive force of the UV color correction liquid on the bottom paint film is further improved.
