Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window material for an automobile, a window material for another vehicle, or a light cover, for example.
The present invention relates to a transparent resin laminate having a shielding portion and used as a device cover or the like.

[0002]

2. Description of the Related Art In recent years, transparent resin molded articles have been widely used as glass substitute materials because of their excellent impact resistance, light weight, and workability. For example, they are used as window materials for automobiles such as rear windows, window materials for trains, and window materials for buildings such as buildings. In general, such a transparent resin molded body is attached to a member such as a vehicle body to be attached with an adhesive. A colored shielding layer is usually provided on the bonding point so that the bonding point does not enter the field of view, since the color shielding layer is lowered so as to significantly lower the product value.

On the other hand, since the resin molded article is generally easily damaged, it is usually necessary to cover the outermost surface with a hard coat layer having good scratch resistance. As such a hard coat layer, a silicone-based one having excellent scratch resistance is often used.

[0004] However, the silicone-based hard coat layer has poor hydrophilicity and is chemically stable, and thus has a problem of poor adhesion to the colored shielding layer.

Japanese Patent Publication No. Hei 7-25910 discloses a polymethyl methacrylate primer layer between a colored shielding layer and a hard coat layer, and a vinyl-acrylic resin based resin as a resin constituting the colored shielding layer. It has been proposed to use at least one specific resin selected from the group consisting of vinyl, methacrylic resin, and modified polyester resin. This makes it possible to obtain a material having excellent adhesion between the layers.

[0006]

However, the above-mentioned specific resin used as a resin constituting the colored shielding layer in the above prior art has a problem that the solvent resistance is not good. That is, before the hard coat layer is formed, an operation of wiping with a cleaning cloth soaked with alcohol to clean the surface is performed. At this time, the resin constituting the colored shielding layer slightly dissolves in the cleaning alcohol. . Since the melted-out resin adheres to the cleaning cloth, if the transparent portion is wiped as it is, a wiping mark is formed, and if the hard coat layer is directly coated, the appearance becomes poor. Therefore, the transparent part and the colored shielding layer must be separated and wiped with separate cleaning cloths, which is not only complicated, but also the boundary between the transparent part and the colored shielding layer must be meticulous. Therefore, it was very troublesome and productivity was poor. In addition, since even a small amount of the resin is melted, it is difficult to reliably avoid wiping marks at the boundary.

Further, when the colored shielding layer is formed and then immersed in a primer solution for forming a primer layer, the resin constituting the colored shielding layer slightly dissolves into the primer solution, and the primer is immersed every time the immersion is performed. There was also a problem that the solution life of the primer solution was shortened because the amount of dissolution in the solution increased.

The present invention has been made in view of such technical background, and has excellent weather resistance and abrasion resistance, good adhesion of each constituent layer, and a colored shielding layer having a solvent resistance. It is an object of the present invention to provide a transparent resin laminate having a shielding portion which is excellent, and thus has excellent product appearance and productivity.

[0009]

Means for Solving the Problems In order to achieve the above object, the present inventors have made intensive studies and found that the primer layer is composed of an acrylic resin, the hard coat layer is composed of a silicone compound, and By forming the colored shielding layer with a specific crosslinked resin, it has been found that a transparent resin laminate having the desired shielding portion can be obtained, and the present invention has been completed.

That is, in the transparent resin laminate having the shielding portion according to the present invention, a colored shielding layer made of a resin is laminated at a predetermined position on the surface of the transparent resin substrate, and at least on the side where the colored shielding layer is formed. In a transparent resin laminate having a shielding portion in which a primer layer made of an acrylic resin and a silicone hard coat layer are sequentially laminated and integrated, the resin constituting the colored shielding layer has a functional group having an active hydrogen molecule. A curable resin composition comprising a vinyl chloride-vinyl acetate copolymer resin having two or more and a urethane resin having two or more functional groups having active hydrogen in the molecule,
It comprises a crosslinked resin obtained by reacting with a polyisocyanate compound.

Since the colored shielding layer is made of a crosslinked resin in which the above two specific resin components are crosslinked with polyisocyanate, it has extremely excellent solvent resistance and also has excellent adhesion between the colored shielding layer and the primer layer. Also, the adhesiveness between the colored shielding layer and the transparent resin substrate is excellent. Since the resin has excellent solvent resistance, the resin does not elute there even when immersed in the primer solution, so that the life of the primer solution is greatly extended. In addition, because of its excellent solvent resistance, even when wiping with a cleaning cloth impregnated with a solvent before forming the hard coat layer, it is possible to wipe without any problem without distinguishing the transparent portion and the shielding layer from the surface. Easy to clean for wiping and excellent production efficiency.

In the above, the functional group having active hydrogen is preferably a hydroxyl group. Since the hydroxyl group has excellent reactivity with the isocyanate, the curing (crosslinking) time is shortened, and the production efficiency is improved.

The transparent resin substrate is preferably made of a polycarbonate resin. Thereby, the adhesion durability between the transparent resin substrate and the primer layer (acrylic resin) can be further improved.

Further, the mixing weight ratio of vinyl chloride-vinyl acetate copolymer resin / urethane resin in the curable resin composition is preferably in the range of 80/20 to 60/40. Within this range, not only the adhesion durability between the colored shielding layer and the primer layer can be further improved, but also the reliability of preventing cracks in the hard coat layer can be further improved.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION In a transparent resin laminate (1) according to the present invention, a colored shielding layer (3) made of a resin is laminated at a predetermined position on the surface of a transparent resin substrate (2). On the side where the layer (3) is formed, a primer layer (4) made of an acrylic resin and a silicone hard coat layer (5) are sequentially laminated and integrated, and constitute a colored shielding layer (3). The main characteristic is that a specific cross-linked resin is used as the resin to be formed. FIG. 1 shows a cross-sectional view of a transparent resin laminate (1) having a shielding portion according to one embodiment. The transparent resin laminate (1) of the present embodiment includes:
It is suitably used as a window material for automobiles, in which a colored shielding layer (3) is provided on a peripheral portion of one surface of a transparent resin substrate (2).

In the present invention, the resin constituting the transparent resin substrate (2) is not particularly limited as long as it is a synthetic resin. For example, acrylic resin, impact-resistant acrylic resin, heat-resistant acrylic resin, polycarbonate, polyarylate, polysulfone And the like. Among them, polycarbonate is preferred because it has excellent adhesion durability with a primer layer made of an acrylic resin, has excellent adhesion durability with a silicone hard coat layer, and has a good balance of physical properties. The transparent resin substrate (2) may be colorless and transparent, or may be colored and transparent.

In the present invention, the resin constituting the colored shielding layer (3) needs to be composed of a crosslinked resin obtained by reacting an isocyanate-curable resin composition with a polyisocyanate compound.

Further, the isocyanate-curable resin composition includes a vinyl chloride-vinyl acetate copolymer resin having two or more functional groups having active hydrogen in the molecule, and a functional group having active hydrogen in the molecule. It is necessary to be composed of two or more urethane resins.

The functional group having active hydrogen includes, for example, a hydroxyl group, a mercapto group, a carboxyl group, an amino group and the like. Among them, a hydroxyl group which is excellent in reactivity with isocyanate and can improve productivity is preferable.

The mixing weight ratio of vinyl chloride-vinyl acetate copolymer resin / urethane resin in the curable resin composition is desirably in the range of 80/20 to 60/40.
If the mixing ratio of the vinyl chloride-vinyl acetate copolymer resin is smaller than the above range, the adhesion to the primer layer (4) is undesirably reduced. On the other hand, if the mixing ratio of the vinyl chloride-vinyl acetate copolymer resin is larger than the above range, cracks tend to occur in the hard coat layer (5), which is not preferable.

On the other hand, the polyisocyanate compound is not particularly limited as long as it has two or more isocyanate groups in the molecule. For example, tolylene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), polymethylene polyphenyl Polyisocyanate (polymeric MDI), tetramethylene diisocyanate, hexamethylene diisocyanate (HMD)
I), isophorone diisocyanate (IPDI), xylylene diisocyanate (XDI), hydrogenated xylylene diisocyanate (hydrogenated XDI), dicyclohexylmethane diisocyanate (hydrogenated MDI) and the like. These polyisocyanates may be used alone or 2
More than one species can be used in combination.

In the present invention, as the resin constituting the colored shielding layer (3), a crosslinked resin obtained by reacting the above-mentioned isocyanate-curable resin composition with a polyisocyanate compound is used. The reaction (curing) is preferably carried out at a temperature of 80 to 100 ° C. In this case, the desired cured colored shielding layer (3) can be formed in about 10 to 30 minutes. Of course, the curing reaction may be performed outside of the above temperature range.
If the temperature is lower than 100 ° C., the time required for curing becomes longer. On the other hand, if the temperature is higher than 100 ° C., the formed colored shielding layer (3) tends to crack, which is not preferable.

The thickness of the colored shielding layer (3) is from 1 to 10
It is preferably set to μm. If the thickness is less than 1 μm, sufficient shielding properties cannot be obtained, which is not preferable. On the other hand, if it exceeds 10 μm, it is not preferable because liquid dripping easily occurs and the appearance of the product tends to be poor.

The coloring shielding layer (3) contains a coloring agent such as a pigment or a dye in order to secure the shielding property. The coloring color is preferably black.

In the present invention, it is necessary to use an acrylic resin as the resin constituting the primer layer (4). The acrylic resin is not particularly limited, but is preferably an acrylic polymer or a copolymer of an acrylic monomer and another monomer copolymerizable therewith. Note that the acrylic resin is used in a concept including a methacrylic resin. The primer layer (4) may contain an ultraviolet absorber as needed. In forming the primer layer (4), usually, a solution obtained by dissolving the acrylic resin in an organic solvent is applied, and then the solvent is dried to form the primer layer.

The primer layer (4) may be formed at least on the side on which the colored shielding layer (3) is provided, but usually, a hard coat layer (5) is provided on both surfaces. Accordingly, it is preferable that the primer layer (4) is also formed on the entire surface on both sides of the transparent resin substrate (2).

The primer layer (4) has a thickness of 1 to 5
It is preferably set to μm. When the thickness is less than 1 μm, the adhesion to the hard coat layer (5) is unpreferably reduced. On the other hand, when the thickness is more than 5 μm, the adhesion to the transparent resin substrate (2) is undesirably reduced.

In the present invention, the hard coat layer (5)
Must be composed of a silicone compound. Although it does not specifically limit as a silicone type compound, For example, the polymer etc. which have an organopolysiloxane in a skeleton are mentioned.

Among them, the general formula RSi (OH) ₃ (where,
In the formula, R is an alkyl group having 1 to 3 carbon atoms, a vinyl group,
3,3-trifluoropropyl group, γ-aminopropyl group, γ-methacryloxypropyl group or γ-glycidoxypropyl group). Can further improve the adhesiveness with the primer layer (4) and can obtain excellent scratch resistance as a hard coat layer.

Further, the hard coat layer (5) preferably contains colloidal silica. Such a hard coat layer (5) can be formed by coating an aqueous dispersion or an alcohol dispersion of the partial condensate and colloidal silica.

The thickness of the hard coat layer (5) is 1 to
It is preferably 5 μm. If it is less than 1 μm, the scratch resistance is reduced, and it is not preferable. If it is more than 5 μm, cracks are easily generated in the hard coat layer.

The transparent resin laminate (1) having the shielding portion of the present invention can be manufactured, for example, as follows.

First, a printing ink prepared by dissolving the above-described isocyanate-curable resin composition and a polyisocyanate compound in an organic solvent is prepared. Although it does not specifically limit as an organic solvent, For example, ketone solvent, ester solvent, aromatic hydrocarbon solvent, etc. are mentioned. A colorant is dissolved or dispersed in the printing ink. This printing ink is printed at a predetermined position on the transparent resin substrate (2) by a method such as screen printing, pad printing, offset printing, gravure printing, brush coating, or the like. Among the above printing methods, screen printing that can control a desired film thickness with higher accuracy is preferable. Next, it is cured by heating (crosslinking) to form a colored shielding layer (3).

Next, if necessary, the transparent resin substrate (2) on which the colored shielding layer (3) is formed is thermoformed to a desired shape.

Next, a primer solution obtained by dissolving an acrylic resin in an organic solvent is applied by a dipping method (dip coating method) or the like, and dried by heating. The heating temperature at this time is usually 100 to 130 ° C. The organic solvent constituting the primer solution is not particularly limited, and examples thereof include ethyl cellosolve, methoxypropanol, and isopropyl alcohol.

Further, a hard coat solution in which a silicone compound is dissolved in an organic solvent is dipped (dip coat method).

[0066]

As described above, in the transparent resin laminate having the shielding portion of the present invention, the colored shielding layer is made of a crosslinked resin in which two specific resin components are crosslinked with polyisocyanate. It has excellent adhesion to the primer layer and also excellent adhesion between the colored shielding layer and the transparent resin substrate. In addition, since the colored shielding layer is made of the above-mentioned specific crosslinked resin, it is extremely excellent in solvent resistance. Therefore, when wiping with a solvent-impregnated cleaning cloth before forming the hard coat layer, the resin constituting the colored shielding layer does not dissolve in the solvent, and the surface can be cleaned without so-called wiping marks. The appearance quality of the product can be improved. In addition, since the resin does not dissolve out, it is not necessary to wipe the boundary between the transparent portion and the shielding layer with great care as in the related art. Therefore, there is an advantage that the wiping is not troublesome and the productivity is excellent. Furthermore, since the resin is excellent in solvent resistance, the resin does not elute there even when immersed in the primer solution, so that the life of the primer solution can be significantly extended. Therefore, not only the cost can be reduced, but also the amount of the primer solution that cannot be used and is discarded is remarkably reduced, so that there is an advantage that the burden on the environment can be reduced. Further, since the surface layer is covered with the silicone-based hard coat layer, it has excellent scratch resistance.

When the functional group having an active hydrogen is a hydroxyl group, the curing (crosslinking) rate is high, so that the productivity can be improved.

When the transparent resin substrate is made of a polycarbonate resin, the adhesion durability between the transparent resin substrate and the primer layer can be further improved.

Further, when the mixing weight ratio of the vinyl chloride-vinyl acetate copolymer resin / urethane resin in the curable resin composition is in the range of 80/20 to 60/40, the color shielding layer and the primer layer The adhesion durability can be further improved, and the occurrence of cracks in the hard coat layer can be more reliably prevented.
