Description

[Detailed description of the invention] The wooden invention relates to a long flooring made of vinyl chloride resin with excellent heat resistance. To provide a long flooring material made of vinyl chloride resin which has excellent tobacco resistance and does not cause the surface to melt and adhere to cigarette ash, or to cause significant discoloration or scorch marks.

Conventionally, long flooring materials have been used with a non-crosslinked vinyl chloride resin layer or rubber layer laminated on a base material, or both of these materials have poor heat resistance, making it difficult to leave lit cigarettes on the flooring materials. If you rub the cigarette on the flooring material, the surface will melt and cigarette ash will stick to it, or even if it doesn't melt, cigarette ash will stick to it, making it look bad. It also had the disadvantage of causing significant discoloration, scorch marks, etc.

As an improved product that has improved the above-mentioned drawbacks, a product has been developed in which a thin layer of polyurethane coating is laminated on the surface of a long flooring material with a non-crosslinked vinyl chloride resin layer or a rubber layer laminated on the base material. Since the urethane coating layer is a thin layer, it is not durable, and if used for a long time, the non-crosslinked vinyl chloride resin and rubber layer under the thin urethane coating layer will appear directly on the surface, similar to conventional long flooring materials. Not only does this expose the shortcomings of the urethane coating, but when a lit cigarette is left unattended or the cigarette is rubbed to extinguish, the heat is directly conducted under the urethane coating layer, melting the urethane coating layer and causing an unsightly appearance. It was something that would get worse.

If the urethane coating layer is made thicker, the above defect 01 can be improved, but making the urethane coating layer thicker not only worsens the workability in production, but also makes it difficult to apply a solution of urethane resin to the urethane coating layer. Since it is formed by drying, bubbles are generated when the solvent contained in the solution is volatilized by heating, and air is drawn into the wax coating layer, making it impossible to obtain a good product.

In addition, in order to improve the cushioning properties of these conventional flooring materials, a material containing a foamed synthetic resin layer is used as the base material, a vinyl chloride resin layer laminated to the base material, or a rubber layer containing a foamed layer. If the foamed synthetic resin layer or foam layer acts as a heat insulator, it will prevent heat from dissipating when a lit cigarette is left on the flooring or when the cigarette is rubbed out. This was not preferable because the heat was trapped and the discoloration was more pronounced than in the case without a foam layer, and the scorch marks were deeper and holes were formed in some cases.

This invention improves the drawbacks of these conventional long flooring materials,
It is an object of the present invention to provide a long flooring material which has excellent resistance to cigarette fire, shows almost no discoloration even when it includes a foam layer, and does not cause scorch marks.

That is, the flooring material with good cigarette fire resistance of the present invention has a vinyl chloride resin undercoat layer 2 laminated on the surface of the base material 1, and a layer 3 with high thermal conductivity is laminated on the vinyl chloride resin undercoat layer 2. In addition, in a laminated sheet in which a heat-resistant vinyl chloride resin top layer 5 is laminated on the high thermal conductivity layer 3, the high thermal conductivity layer 3 and the heat-resistant vinyl chloride resin top layer 5 are laminated. A printed layer 4 is interposed between them.

The base material 1 includes base fabrics such as woven fabrics, knitted fabrics, and nonwoven fabrics, paper materials,
In addition to synthetic resin sheets and synthetic resin leather, heat-resistant and fire-resistant sheets such as asbestos sheets can be used.

As the paper material, commonly used papers such as kraft paper and Japanese paper can be used.

Synthetic resin sheets include various types of foamed and non-foamed synthetic resin sheets, as well as those in which a foamed or non-foamed synthetic resin layer is laminated on at least one side of a heat-resistant, fire-resistant sheet such as paper or asbestos sheet. Can be used.

As the synthetic resin leather, a woven fabric, a knitted fabric, a non-woven fabric, etc. with a foamed or non-foamed synthetic resin layer laminated on at least one surface can be used.

In addition, the synthetic resin layers to be laminated may be multi-layered or single-layered, and in the case of multi-layers, only non-foamed synthetic resin layers may be multi-layered, or only foamed synthetic resin layers may be multi-layered. It may also be a multilayer structure made by combining a non-foamed synthetic resin layer and a foamed synthetic resin layer.

The vinyl chloride resin subbing layer 2 laminated on the surface of the base material 1 may be formed of a non-crosslinked vinyl chloride resin composition,
Alternatively, it may be formed from a crosslinked vinyl chloride resin composition.

Furthermore, like the heat-resistant vinyl chloride resin top layer 5 described later, even if it is formed of a crosslinked vinyl chloride resin composition mixed with non-crosslinked vinyl chloride resin chips, a non-crosslinked vinyl chloride resin composition mixed with crosslinked vinyl chloride resin chips can be used. It may be formed from a crosslinked vinyl chloride resin composition, or it may be formed from a crosslinked vinyl chloride resin composition mixed with crosslinked vinyl chloride resin chips.

The vinyl chloride resin undercoat layer 2 may be formed of a foamed vinyl chloride resin composition, or may be formed of a non-foamed vinyl chloride resin composition.

Further, the vinyl chloride resin undercoat layer 2 may be a single layer or a multilayer. In the case of a multilayer, two or more layers of only the crosslinked vinyl chloride resin composition may be formed, or a non-crosslinked chloride resin composition may be formed. The vinyl resin composition alone may be formed into two or more layers, or a crosslinked vinyl chloride resin composition and a non-crosslinked vinyl chloride resin composition may be combined to form two or more layers.

In this case, it is possible to form a multi-layer structure using only the foamed vinyl chloride resin composition, it is also possible to form a multi-layer structure using only the non-foamed vinyl chloride resin composition, or it is possible to form a multi-layer structure using only the foamed vinyl chloride resin composition and the non-foamed vinyl chloride resin composition. It can also be made into a multi-layer structure by combining objects.

The layer 3 with high thermal conductivity laminated on the vinyl chloride resin subbing layer 2 is made of metal foil such as aluminum, copper, iron, silver, magnesium, zinc, etc., or metal thin material such as a thin plate of these metals, metal powder, metal foil strips, metal foil strips or aluminum;
In addition to metals such as copper, iron, silver, magnesium, and zinc plated or vacuum-deposited on at least one side of flexible composite or resin films or heat-resistant and fire-resistant sheets such as paper and asbestos sheets, aluminum, copper, and iron , metal powders such as silver, magnesium, and zinc (including cut metal pieces), or inflexible synthetic resin films mixed with metal foil strips or metal foil strips, etc. can be used.

The layer 3 with high thermal conductivity is a flexible synthetic resin film plated with metal, a flexible synthetic resin film vacuum-deposited with metal, or metal powder, metal foil strips, or metal foil strips. When a flexible synthetic resin film mixed with is used, the flexible synthetic resin film may be either a crosslinked film or a non-crosslinked film.

In order to form the layer 3 with high thermal conductivity on the vinyl chloride resin subbing layer 2, metal plating may be applied directly to the surface of the vinyl chloride resin subbing layer 2, or metal may be deposited by vacuum deposition. Alternatively, an adhesive may be applied to the surface of the vinyl chloride resin undercoat layer 2, metal powder, metal foil strips, or metal foil strips may be uniformly spread and dried. , metal foil, metal sheet, flexible synthetic resin film with metal plating or vacuum-deposited metal, flexible synthetic resin film mixed with metal powder, metal foil strips, metal foil strips, laminated with adhesive. It may be pasted and laminated, or a flexible synthetic resin composite mixed with metal powder, metal foil strips, and metal foil strips may be applied to the surface of the vinyl chloride resin undercoat layer 2, dried, and laminated. It's okay.

Further, the surface of the layer having high thermal conductivity may be printed in one color or in multiple colors as necessary.

The heat-resistant vinyl chloride resin top layer 5 may be any layer that substantially forms a crosslinked vinyl chloride resin layer.

That is, the entire heat-resistant vinyl chloride resin top layer 5 may be formed only from a crosslinked vinyl chloride resin composition, or it may be partially formed from a non-crosslinked vinyl chloride resin composition. .

The heat-resistant vinyl chloride resin top layer 5 may be formed only of a crosslinked vinyl chloride resin composition, or it may be a uniform crosslinked vinyl chloride resin layer containing no chips, or it may be a uniform crosslinked vinyl chloride resin layer containing no chips. This is the case when the layer is a crosslinked vinyl chloride resin layer.

Examples of cases in which a part of the heat-resistant vinyl chloride resin top layer 5 is formed of a non-crosslinked vinyl chloride resin composition include cases in which it is a crosslinked vinyl chloride resin layer mixed with chips made of non-crosslinked vinyl chloride resin; This is the case when the layer is a non-crosslinked vinyl chloride resin layer mixed with vinyl chloride resin chips.

When a portion of the heat-resistant vinyl chloride resin top layer 5 is formed of a non-crosslinked vinyl chloride resin composition, it is preferable to minimize the proportion of the non-crosslinked vinyl chloride resin composition.

Chips made of non-crosslinked vinyl chloride resin and chips made of crosslinked vinyl chloride resin are obtained by molding molded objects such as plate-shaped objects, rod-shaped objects, etc. of non-crosslinked vinyl chloride resin compositions and cross-linked vinyl chloride resin compositions using a crusher such as a pelletizer. In addition to pulverized pieces that have been crushed into unspecified shapes, cut pieces of specific shapes and sizes can also be used.

The cross-linked vinyl chloride resin composition in this case refers to vinyl chloride resin (suspension polymerization resin or emulsion polymerization resin), plasticizer,
In the mixture of stabilizers, PVC crosslinkers or various reactive plasticizers, such as acrylic esters of polyhydric alcohols and/or
Or a mixture of a methacrylic acid ester of a polyhydric alcohol and a polymerization initiator or a diallyl phthalate monomer and/or a diallyl phthalate prepolymer and a polymerization initiator, etc., and heat-cured, or an ultraviolet curable resin and/or a 7-day polymer.
A non-crosslinked vinyl chloride resin composition is one that is UV-cured with a photosensitizer and a PVC crosslinker, various reactive plasticizers, UV-curable resin and/or Or it means excluding nanatsuma etc.
Both can be colored in any color.

The print layer 4 interposed between the heat-resistant vinyl chloride resin upper layer 5 and the high thermal conductivity layer 3 is formed with printing ink that is normally used for printing vinyl chloride resin products.

To form the print layer 4, in addition to general printing methods such as gravure printing, flexographic printing, and screen printing, a transfer printing method in which a pattern previously printed on transfer paper is thermally transferred to the vinyl chloride resin layer can also be applied.

In order to interpose the printed layer 4, printing may be performed on the surface of the layer 3 with high thermal conductivity, and a heat-resistant vinyl chloride resin top layer 5 may be laminated on the surface, or a heat-resistant chloride resin top coat layer 5 prepared in advance may be applied. It is also possible to print on one side of the sheet-like material forming the vinyl resin top layer 5, and to laminate the sheet-like material so that the printed surface is in contact with the surface of the layer 3 having high thermal conductivity.

In this case, both the surface of the layer 3 having high thermal conductivity and one side of the sheet forming the heat-resistant vinyl chloride resin top layer 5 may be printed.

Furthermore, the flooring material with good cigarette fire resistance of the present invention can be provided with a thermosetting or ultraviolet curable paint layer 9 on the surface of the heat-resistant vinyl chloride resin top layer 5, or a graining machine can be applied to the surface. It is also possible to form irregularities by such methods.

Firstly, the flooring material with excellent cigarette fire resistance of the present invention has its surface covered with a heat-resistant PVC resin overcoating layer, so it is not suitable for long flooring materials made of non-crosslinked PVC resin or rubber. It does not have the same heat resistance as long flooring made of wood, and even if a lit cigarette is left on the flooring or the cigarette is rubbed out on the flooring, the surface will melt and the cigarette will remain. A beautiful appearance can always be maintained without ash adhering to the surface of the flooring material or causing significant discoloration or scorch marks.

In addition, the durability is not inferior to that of a thin layer of urethane coating laminated on the surface of a long flooring material made of non-crosslinked vinyl chloride resin, and the vinyl chloride resin undercoat layer can be melted by the heat of a cigarette. It can be used effectively for a long period of time.

Second, since the structure has a layer with high thermal conductivity interposed between the vinyl chloride resin undercoat layer and the heat-resistant vinyl chloride resin top layer, the base material is used to improve the cushioning properties of the flooring material. Even if a base material containing a foamed synthetic resin layer is used as a base material, or a vinyl chloride resin subbing layer or a foamed layer is used,
The heat emitted by a lit cigarette thrown onto the surface of the flooring material, or the heat emitted when rubbing a cigarette on the surface of the flooring material, is not trapped and is dissipated by the layer with high thermal conductivity.
Significant discoloration, unlike long flooring materials containing conventional foam layers.
A flooring material with good cushioning properties and always having a beautiful appearance without causing deep burn marks or burn holes can be obtained.

Third, when the heat-resistant vinyl chloride resin top layer is made of synthetic resin with excellent storm-proofing properties, for example, a cross-linked vinyl chloride resin layer mixed with natural rubber, synthetic rubber, or polyurethane resin chips. In this case, if a part of the synthetic resin chip having excellent flood-proofing performance is exposed on the surface of the crosslinked vinyl chloride resin layer, it also exhibits the effect of preventing debris.

In addition, if the heat-resistant vinyl chloride resin top layer contains chips, the print layer and the chips may work together to create a design problem (
This will also be interesting.

Fourth, as a layer with high thermal conductivity, there is a metal foil, a metal plating layer where the base material is directly plated with metal, a vapor deposited layer where metal is directly deposited on the base material, and a flexible layer where metal is plated or vacuum deposited. When a synthetic resin film is used, and colored metal foil, metal plating layer, or vapor deposition layer is used, there is a difference in thermal conductivity between the heat-resistant vinyl chloride resin overcoat layer and The print layer interposed between the high layer and the layer with high thermal conductivity work together to create a beautiful design, and the heat-resistant vinyl chloride resin top layer contains chips. In some cases, it will have an even better design.

Furthermore, when an aT flexible synthetic resin film mixed with metal powder, metal foil strips, or metal foil strips is used as a layer with high thermal conductivity, the light rays are diffusely reflected, and these diffusely reflected light rays are heat-resistant. Together with the printed pattern interposed between the polyvinyl chloride resin top layer and the high thermal conductivity layer, a beautiful design is created, and these metal powders, metal foil strips, and metal foil strips If it is colored, the design will be even more interesting.

Furthermore, the pattern of the printed layer, the color of the chips mixed in the heat-resistant vinyl chloride resin upper layer, the color of the layer with high thermal conductivity, and the printed pattern applied to the layer with high thermal conductivity can be arbitrarily selected as needed. By changing to , flooring materials with a wide variety of interesting designs can be obtained.
