JPS5845019A - Manufacture of rugged decorative material - Google Patents

Abstract

PURPOSE:To produce a rugged decorative material in which residual strain has disappeared, by providing a heat shrinkable plastic film partly with regions whose heat shrinkability is lowered, and then heating the whole of the heat shrinkable plastic film. CONSTITUTION:Parts of the heat shrinkable plastic film are coated with a material that will cause the heat shrinkability to disappear, that is, a solvent that will permeate the heat shrinkable plastic film and will cause it to become a plasticized state or will partialy dissolve said film or make it swelled. Then, when the whole of said film is heated, the parts of said film where the heat shrinkability is lowered are dented. Thus, only by heating once, a rugged decorative material in which residual strain has disappeared can be produced.

Description

[Detailed description of the invention] The present invention relates to a method for manufacturing a textured decorative material.

A decorative material with unevenness, that is, a textured decorative material, is a decorative material that is given a material feel that is desirable in terms of appearance.In particular, it is a decorative material that has unevenness that matches a printed pattern, especially a specific pattern among the printed patterns. Fl1w is heavily used to reproduce the feel of materials such as natural wood, stone, and artificial cloth. A method for imparting cape-like unevenness to a specific pattern among such printed patterns is called a synchronized embossing method, and various methods for this are already known and have been put into practical use.

The inventor of the present invention has developed a technology for manufacturing uneven decorative materials by providing a heat-shrinkable film with a heat ray-absorbing pattern and irradiating it with heat rays to form holes or recesses in the machine parts. Disclosed (Special Publication No. 55-14809
, Japanese Patent Publication No. 55-4579, etc.) 0 or above, it is possible to easily produce a pattern and a rugged unevenness, but when providing a heat ray-absorbing pattern, there are restrictions on the hue that makes it easy to absorb heat rays. This has the drawback that the hue of the concave portion is limited, and the ability to see from a distance is limited.

Father, according to the conventional method, heating is selectively applied to the heat-absorbing pattern area, so other areas still have heat shrinkage even after thermal II stone spraying, and are not composited with other base materials. There are drawbacks such as shrinkage and warping afterward, or gaps at seams, and to eliminate these drawbacks, it is necessary to separately perform uniform heating called heat setting, which is complicated.

The inventor of the present invention has conducted studies to overcome the drawbacks of the conventional method, and has overcome the drawbacks of the conventional method by adopting the structure of claim 411.

The present invention will be explained in detail below.

The heat-shrinkable plastic film used in this invention may be formed by forming a film or sheet by a calendering method, an extrusion method, a casting method, etc., and then performing a rolling process, or by stretching the film or sheet during film formation by an inflation method, etc. A film or sheet manufactured by a method of Vinylidene film, polyvinyl alcohol film, polyethylene terephthalate film, poly9★-bonate film, nylon film, porous brene film, ethylene II/III vinyl copolymer film, ethylene vinyl alcohol copolymer film,
A film or sheet such as an ionomer or acrylic film can be used, and the thickness is 10 to 500 mm. Mll, preferably 40-15G, all. “As for heat shrinkability, the shrinkage rate before and after heating in an open air at 85°C for 15 minutes is 5 to 70-1, preferably 5 to 4.
It is desirable that it be 0-.

The above heat-shrinkable plastic films may be used alone or in combination with other heat-shrinkable plastic films, or may be used in combination with any base material that does not have heat-shrinkability. It may be made into a composite body, and the composite body described in item 1 may be produced before or after providing the region with reduced heat shrinkability as described below, or after the process of heating the entire body as described below. good.

Substrates for bathing the above-mentioned composite include those made of the same material as the heat-shrinkable plastic film mentioned above and having virtually no heat-shrinkability, paper, gypsum board paper, Enoki paper, iron, steel, Electrodeposition of metals such as aluminum and tin, boards, wood, bamboo, and plywood.

and wooden substrates such as verticle board, gypsum-based substrates such as gypsum board and gypsum slag, fiber cement boards such as stone wire cement board, pulp cement board and wood chip cement board, GRO and Hunkrat board, etc. I can do it.

Next, we will discuss how to provide a region with reduced heat shrinkability in a part of the heat-shrinkable plastic film as described above. One of the various methods is possible. ``Method of partially fixing it on other substrates so as not to impair heat shrinkability; The heat-shrinkable plastic film 9' is coated with a printing ink containing a substance that has the function of eliminating heat-shrinkability. Specifically, the substance that causes the heat-shrinkable plastic film to lose its heat-shrinkable properties is a substance that penetrates into the heat-shrinkable plastic film to form a plasticized portion or that partially causes the heat-shrinkable plastic film to lose its heat shrinkability. A swelling solvent is needed,
If the thermo-shrinkable plastic film is, for example, a polyvinyl chloride film, acetone, methyminityl, methyl isobutyl ketone, etc. Type 2, Vinegar #), Y, Vinegar-1

For Ayacol film: water and alcohol, etc. for porous brene film, acetone, ketones such as methyl ether ketone and methyl isobutyl ketone, alcohol such as methyl alcohol, ethyl alcohol, isopropyl alcohol, acrylic For film, acetone,
Ketones such as teletherketoshi and methyl isobutyl ketone, methyl #acid, ethyl acetate and hbutyl acetate? #acid esters of #1 and aromatic hydrocarbons such as toluene and #2 acid can be used, and in addition to these, vehicles used as components of ordinary inks, electrochromic agents, plasticizers, pigments, Stabilizers, dispersants, fillers, melts, and diluents are kneaded together to create a unique product! Then, a pattern on a desired portion is printed using a known printing method. Vehicles include ethyl cellulose, cellulose derivatives such as ethyl & ε droxyether cellulose, cellulose acetate flobionate, cellulose acetate, polystyrene, ethylene resins such as bo-methylstyrene, and styrene copolymers*m.
, ・Polymethacrylic ether, polyactuate #□ethyl, polybutylacetate, mono or copolymer of acrylic or methacrylic resin v#, rosin, CI! > Modified maleic acid resin, rosin modified phenol resin, ty ester resin such as polymerized rosin, boron vinyl acetate resin, Kuma a/ju Wj, vinyl toluene IIM resin, vinyl chloride resin, polyester resin, polyurethane resin, butyral Using one or more of resin, polyamide resin, vinyl chloride, -vinyl acetate co-combined resin, etc., printing methods include gravure printing 1, gravure offset inkuri, dilitho aim, convex print-1 intaglio printing, This is done by methods such as direct printing and silk screen printing.

In addition to providing a region with reduced heat shrinkability in a part of the heat-shrinkable plastic film as described above, an arbitrary pattern may be provided using a conventional ink and a known printing method.
Any pattern may be provided to match the area of reduced heat shrinkability, and this can be done, for example, by using connected printing and printing units, and The printing methods used in each unit may be the same or different.

After providing six regions with reduced heat shrinkability in a part of the heat-shrinkable plastic film as described above, the entire film is heated. Heating methods include hot air stove, Chikatsu Gaishi, far infrared region,
It can be carried out using open flame, frequency or microwave, hot water, heat waves, hot sand, etc. In addition, heat-shrinkable plastic film alone or a composite of heat-shrinkable plastic films, or a composite of hard-shrinkable plastic film and flexible plastic film, etc., can be heated to a temperature of 70°. For this purpose, a cohesive plastic film or a composite of seven parts is pre-fixed in a frame or a bottle.

It is preferable to heat it while constantly running both ends using a clamp or the like.

Father, after creating a region with low heat shrinkability in a part of the heat shrinkable plastic film, when combining & materials, MIN
When combined using the spear method, I'll suppress the heat of the insect quencher.
You can also use it.

That's all! By heating, a partial recess is formed in a portion of the heat-shrinkable plastic film corresponding to a region with reduced heat yield. The principle behind the formation of recesses is when using a solvent that penetrates the heat-shrinkable plastic film and creates a softened state, or partially dissolves and swells (2) when the softening point of the heat-shrinkable plastic film is Since the movement of molecules becomes easier and easier, it becomes easier to return the stretching by A42 to the A42, which was accumulated by Ayu stretching during film production. It is speculated that this is because the situation 1 occurs in which the system does not have the correct collection power.

Since the present invention has the above configuration, it does not have the disadvantage that concave hues are added, and has the advantage that it can be applied to patterns of all hues.

Also, according to the present invention, as in the conventional method C-1,
IIk It is not necessary to add a certain process, and it is possible to create an uneven decorative material in which residual distortion disappears by -1 heating 42.
