Description

[Detailed description of the invention] [Industrial application field] The present invention is applicable to, for example, synthetic resin tiles and underlays.

This relates to a laminated material used in the production of press-formed objects such as desk mats and credit cards, and it can be used simply by subjecting it to press molding to obtain a press-formed object, that is,
The present invention provides a laminate material that can be formed into a press molded product having an embossed effect that synchronizes with a pattern without applying a mechanical or chemical embossing process.

[Conventional technology]

Synthetic resin molded bodies with embossing that matches the pattern are used as synthetic resin molded bodies for a variety of purposes because the pattern inside the molded body gives a novel feel and exhibits an excellent design effect. has been done.

Therefore, a method for manufacturing a synthetic resin molded body having an embossment that matches the pattern includes (1) filling a decorative sheet with an embossment that matches the pattern with transparent synthetic resin powder; (2) A method of performing press molding without crushing the embossing in (2) a method of performing the embossing process simultaneously with press molding by using a backing plate with an uneven surface in the press molding process;
(3) A method in which the obtained press-molded body is further subjected to a post-emboss process, and (4) a method in which room-temperature curing resin is poured onto a decorative sheet that is embossed to match the pattern and cured. .

[Problem that the invention seeks to solve]

By the way, in the method for manufacturing a synthetic resin molded body having an emboss that matches the pattern, the method using press molding in item (1) requires a step of mechanically attaching an emboss that matches the pattern to a decorative sheet having a pattern. Not only is the process complicated, but the embossing on the decorative sheet is easily crushed. Furthermore, the method in which the embossing step is carried out at the same time as the press forming described in item (2) has the disadvantage that the pattern on the decorative sheet and the embossing are difficult to synchronize, making it difficult to obtain a sheet of good quality. Furthermore, (3)
In the case where the post-emboss process is carried out, as in the case of item (2) above, it is difficult to synchronize the pattern and the emboss, and furthermore, the post-emboss process is complicated.

In addition, the method described in (4) in which room-temperature curable resin is poured requires a process of mechanically attaching an emboss that matches the pattern to a decorative sheet with a pattern, and a process of casting and curing the curable resin. However, there are disadvantages such as not only the process is complicated but also the resins that can be used are limited.

On the other hand, the laminated material for forming a press-formed body having an embossing effect that matches the pattern of the Sphagnum moss invention requires only press molding to obtain a press-formed body from the laminated material.
In other words, it has been possible to provide a laminate material that can be formed into a press-formed product having an embossed effect that synchronizes with the pattern without providing a mechanical or chemical embossing process.

It has been confirmed that by press-molding the material, a press-formed product with a more pronounced embossing effect that matches the above-mentioned pattern can be formed.

The thermoplastic resin layer involved in compression during press molding in the laminate is a layer that becomes the thermoplastic resin layer in the molded product that is the target product obtained by press molding. ．． The intervening film layer in the laminate materials of the fourth and fifth inventions is not a thermoplastic resin layer that participates in compression during press molding. Further, when the laminated material is subjected to press molding, the time point at which the thickness of the thermoplastic resin layer in the laminated material involved in compression during press molding is compressed to 90 to 40% of that at the start of press molding is, When the press pressure is kept constant throughout the pressurization period, that is, when the initial maximum press pressure is maintained, the pressure is about 1 It has been found that this can be achieved in a press time of /2. Further, in the press molding, the thickness of the thermoplastic resin layer at the start of cooling in the press molding is 90% of the initial thickness.
If it exceeds 40%, the unevenness effect of the embossing will be insufficient, and if it is less than 40%, there will be a problem that the displayed pattern will be disturbed. Therefore, in order to produce a stable pattern with a remarkable embossed effect, it is preferable to start the cooling process following the heating in press molding when the compression is about 80 to 60%. Temperature used in forming press-formed bodies.

It is preferable that the press molding be performed under press conditions of higher temperature and pressure than the pressure.

This resulted in a press-molded product with an extremely innovative and highly designed design for use in illuminated signboards.

[Action of the invention]

The laminated material for forming a press molded body having an emboss effect in synchronization with the pattern of each of the present inventions includes a decorative sheet made of a thermoplastic resin sheet having a pattern layer formed by printing ink, and a layer in contact with the decorative sheet. A thermally bonded laminate with the above thermoplastic resin layer, or an intervening film layer having specific physical properties, a thermoplastic resin sheet serving as a base material for a decorative sheet, and one or more layers in contact with the thermoplastic resin sheet. This is a thermally bonded laminate of the thermoplastic resin layer and the printed pattern layer provided on the intervening film layer or the thermoplastic resin sheet serving as the base material for the decorative sheet, and the laminate is made into a press-molded product. Simply by being heated and pressurized, the printed pattern layer is distorted due to the difference in flow behavior when the thermoplastic resin sheet, which is the base material for the decorative sheet, and the printed pattern layer are melted at the same temperature. A press molded article is obtained in which the resin is introduced into a thermoplastic resin layer that is in contact with the printed pattern layer in the thickness direction, or into the printed pattern layer and a thermoplastic resin layer that is in contact with the printed pattern layer in the thickness direction. By doing so, it is possible to obtain a press-molded product having an embossed effect that matches the pattern.

During the process in which the laminated material for forming the press-formed body of each of the present inventions is subjected to press-forming, the above-mentioned distortion is introduced into the press-formed body, and the printed pattern layer protrudes upward, resulting in an embossment that is synchronized with the pattern. It is presumed that the mechanism of forming into a press-formed body exhibiting the effect is as follows.

First, in the case where the melting temperature of the thermoplastic resin (vehicle) constituting the printed pattern layer in the laminate material for press molding is lower than the melting temperature of the thermoplastic resin sheet that is the base material for the decorative sheet, this ．． Third. And in the laminated materials of the fifth invention, when these laminated materials are subjected to press molding and heated, the printed pattern layer portion first melts, and in the melted portion, the printed pattern layer portion melts. As a result, an intermediate stage is realized in which the flow resistance in the horizontal direction in the thickness direction of the laminate between the press platen or the intervening film is reduced, and the press forming progresses further, and the whole softens and is placed under pressure. It will be destroyed. For this reason, the thermoplastic resin layer in the laminate starts to flow, but this flow rate is greater in areas near the press platen or intervening film than in areas far away, so that the laminate A flow velocity distribution will occur in the thickness direction. In the printed pattern layer and the thermoplastic resin layer portion that is in contact with the pattern layer in the thickness direction, the flow is further promoted because the resistance of the printed pattern layer to the press surface plate or the intervening film is small. Therefore, it is presumed that this is because distortion occurs and becomes fixed in such a state. Also,
In the laminated materials of the second and fourth inventions, when these laminated materials are subjected to press molding and heated, the printed pattern layer portion first melts, and at least the printed pattern layer in the thickness direction melts. After the upper and lower thermoplastic resin layers achieve an intermediate stage in which the flow resistance in the horizontal direction relative to the thickness of the laminate is reduced, press molding proceeds further to soften the entire material and place it under pressure. That will happen. For this reason, the thermoplastic resin layer in the laminate material begins to flow horizontally, but this flow is slower in areas near the intervening film or press surface plate than in areas further away. , a distribution occurs in the flow velocity in the thickness direction of the laminated material. This flow is promoted in the printed pattern layer portion because the resistance to horizontal flow is reduced in the thermoplastic resin layer that is in contact with at least the top and bottom of the pattern layer in the thickness direction, and the flow rate is increased. It is presumed that this is because the pressure in the faster parts becomes greater, and in this state distortion occurs and becomes fixed.

Furthermore, in the case where the melting temperature of the thermoplastic resin (vehicle) constituting the printed pattern layer in the laminate material for press molding is higher than the melting temperature of the thermoplastic resin sheet serving as the base material for the decorative sheet, ．． Third. And in the laminated material of the fifth invention, when these laminated materials are subjected to press molding and heated, the portion of the thermoplastic resin sheet serving as the base material for the decorative sheet, to which the printed pattern layer is not in contact, melts. death,
In the melted part, an intermediate stage is realized in which the flow resistance in the horizontal direction with respect to the thickness direction of the laminate material between the press platen or the intervening film is reduced, and the press forming further progresses and the entire material becomes soft and It will be placed under pressure.

For this reason, the thermoplastic resin layer in the laminate starts to flow, and this flow rate is greater in areas near the press platen or intervening film than in areas farther away, so that the thickness A flow velocity distribution will occur in the direction.

In addition, in the thermoplastic resin sheet portion that is the base material for the decorative sheet in the part of the laminate where the printed pattern layer does not exist, the resistance between the thermoplastic resin layer and the press surface plate or the intervening film is small. This is presumed to be due to the fact that the flow is promoted and the pressure in the areas where the flow rate is high is greater, and in such a state distortion occurs and becomes fixed. Moreover, in the laminated materials of the second and fourth inventions, when these laminated materials are subjected to press molding and heated, the printed pattern layer of the thermoplastic resin sheet, which is the base material for the decorative sheet, comes into contact with the laminated materials. The part that is not printed is melted, and is at least above the surface of the non-printed pattern layer in the thickness direction.

After an intermediate stage is achieved in which the flow resistance in the horizontal direction with respect to the thickness direction of the laminate is reduced in the thermoplastic resin layer of the lower part, the press molding proceeds further to soften the entire material and to place it under pressure. That will happen. For this reason, the thermoplastic resin layer in the laminate material begins to flow horizontally, but this flow is slower in areas near the intervening film or press surface plate than in areas further away. , a distribution occurs in the flow velocity in the thickness direction of the laminated material. This flow is promoted because the resistance to horizontal flow is reduced in the thermoplastic resin layer that is in contact with at least the upper and lower sides of the non-printing layer surface, and the pressure in the areas where the flow rate is high becomes greater, causing the It is presumed that this is because distortion occurs in the state and becomes fixed.

In addition, this book No. 1. Third. And in the laminated material of the fifth invention, the effect is sufficiently effective when the difference in melting point between the thermoplastic resin (vehicle) in the printed pattern layer and the thermoplastic resin sheet serving as the base material for the decorative sheet is 5°C or more. It has been confirmed that a certain embossment can appear, and in the laminated materials of the second and fourth inventions, the melting point of the vehicle in the printed pattern layer and the heat directly in contact with the printed pattern layer are It has been confirmed that a sufficiently effective embossing appears when the difference from the melting point of the plastic resin layer is 5° C. or more. In addition, there is no particular limit on the upper limit of the difference between the melting point of the vehicle in the printing pattern layer and the melting point of the thermoplastic resin layer that is in direct contact with the printing layer, but Due to problems, etc., a melting point temperature difference of up to about 40°C is practically usable.

Also, book No. 1. Third. And in the laminate material of the fifth invention, thermal melting behavior between the thermoplastic resin sheet serving as the base material for the decorative sheet and the thermoplastic resin layer in contact with the thermoplastic resin sheet on the opposite side of the printed pattern layer. In the laminate materials of the second and fourth inventions, the thermoplastic resin layers constituting the upper and lower layers of the printed pattern layer each have a different embossing effect. It has been confirmed that when the thermal melting behavior of the materials is different from each other, a press-formed product with a higher embossing effect can be obtained.

Furthermore, in the laminated materials of the present invention, when a printed pattern layer is present at or near the center in the thickness direction of the thermoplastic resin layer other than the intervening film layer in the laminated materials, the laminated materials can be pressed with a noticeable embossing effect. It is difficult to form a molded object, and especially when the thermoplastic resins in the thermoplastic resin layers above and below the printed pattern layer are the same, the emboss effect is difficult to appear. It is preferable to have a laminated structure in which the thermoplastic resin layer is exposed upward in the direction, that is, above the center of the thermoplastic resin layer in the obtained press-molded body.

〔Effect of the invention〕

The laminated material for forming a press-formed body having an embossed effect that synchronizes with the pattern of each of the present inventions can produce an embossed effect that synchronizes with the pattern simply by subjecting it to ordinary press molding to form a press-formed body. This is because it is a press-molded body that exhibits an embossed effect that matches the pattern without requiring any mechanical or chemical processes to apply the embossing. The present invention has the effect that a press molded article having an embossing effect that matches the pattern and having a high design effect can be easily and simply molded.

Furthermore, when the laminated material for forming a press-molded body of each of the present inventions is heated and pressurized for press-molding, the above-mentioned thermoplastic resin layer and printed pattern layer flow due to thermal melting. Distortion caused by the difference in behavior is introduced into the thermoplastic resin layer, and an embossed effect that synchronizes with the pattern is produced, so that the printed pattern layer and the unevenness of the embossed effect in the resulting press-formed product are perfectly aligned. The action of forming a press-formed body that is in tune with the

It is also effective.

Furthermore, the laminated materials of each of the present inventions can be made by selecting the type and thickness of the resin of the thermoplastic resin layer in the laminated materials, and by adjusting the press molding conditions when subjecting the laminated materials to press molding as appropriate. Depending on the selection, etc., the height and lowness of the embossing appearing in the press-formed body can be arbitrarily adjusted.

Further, among the laminate materials of the present invention, a laminate material to which an intervening film layer is added, that is, a third laminate material. In the laminate material of the fourth and fifth inventions, the tendency of the thermoplastic resin layer in contact with the intervening film layer to extend in the horizontal direction is suppressed during press molding of the laminate material, or As a result, the distortion caused by the difference in flow behavior due to thermal melting between the thermoplastic resin layer and the printed pattern layer is more pronounced, and press molding with extremely clear embossed unevenness is achieved. It has the function and effect of being molded into the body.

Furthermore, since the laminated materials for forming press-formed bodies of the present invention are made of thermally bonded laminated materials, they are easier to handle than those made of simple laminated materials, and are free from dust and the like during the molding process. It is characterized by the action and effect that it is molded into a high-quality press-formed product without any contamination between layers or the generation of chicks in the molded product.
