CONSTITUTION:A fiber sheetlike material base is provided with a sheetlike material by using a composition containing a material substance such as coarse particles or fibrous substance showing decorative appearance or becoming a binding material of partial cracking, the laminated is processed by vibration, bending or rubbing and damaged through partial cracking, fracture, etc., the composition is partially exposed and in a state of damaged appearance shape approximately maintained, damaged parts are partially connected or reinforced and the composition is prevented from releasing from the reinforced base to give a sheetlike material having partially unproportionally exposed part of composition.

Description

[Detailed Description of the Invention] (a) Industrial Application Fields Processed products made from the sheet-like material of this invention are used for personal items such as cases and bags, accessories such as hats and belts, clothing, lighting equipment, etc. It relates to things used for covers, wall-mounted 1-inch rears, etc.

(b) Conventional technology Conventional sheet materials and artificial leather have had defects due to deep drawing and cracks due to deterioration. In addition, there were cases where the binder of the sheet-like material was partially destroyed, or where some of the constituent layers were partially destroyed.

(c) Problems to be Solved by the Invention In a sorted product consisting of a single layer or multiple layers, the binder forming the sheet may be partially destroyed or any of the constituent layers may be damaged. Even if there is partial destruction or damage, if the broken, damaged or cracked part remains as it is, it will be weak when external force is applied, and it will not be able to hold the sheet shape or will be easily detached from the base material. Become.

Therefore, it is used as a means of reinforcing damaged parts.

Spraying or coating with synthetic resin liquid, etc., or laminating with plastic film, etc.

From the beginning, efforts were made to adjust the degree of damage by creating a multilayer structure and making the binder non-uniform.

However, these measures may cause natural damage.

It does not mean that the state of destruction, cracks, cracks, etc. is maintained as it is, and the natural feeling is spoiled.

) Means to solve the problem Even if it means destruction, cracks, and crack formation.

There are few parts of the formed layered sheet material that completely crack in the thickness direction, and the vertical cracks do not completely extend to the base material, but are connected little by little at some point.

External energy that melts these parts and the parts that form the binder while maintaining their shape and strengthens the connected parts, such as energy that is compatible with the part that forms the binder, Ultraviolet rays, infrared rays, two electron beams, etc. were added.

In addition, tangible materials 2 that do not physically crack or crack, such as long or short fibers or fibrous materials, coarse grains or granules, etc., may be included in the composition constituting the sheet-like material to prevent cracks or cracks. I wanted it to be a connection.

The above is a physicochemical method, but at the same time.

By bending, rubbing, etc., using a decorative material included in the composition, it is brought out, the natural feel is further emphasized, and the decorative property is imparted.

(E) Function The composition forming the sheet-like material contains a tangible substance and also contains a substance that serves as a binder for the tangible substance.

Binders include tangible materials depending on the type, but the components mainly used as binders are liquid at room temperature.
In addition, solid materials undergo plastic flow when heated, become sheet-like materials, and when heat or other energy is applied to them, they can self-crosslink, undergo two reactions, or melt.
It activates and strengthens connected and contact areas.

Also, the inclusion of tangible objects is not only decorative.

It is in a state of bridging cracks and cracks,
This forms a connected portion, which prevents the shape of the sheet-like material from collapsing and prevents partial peeling or detachment from the two base materials.

(f) Example 100 parts of emulsion polymerization type vinyl resin, 90 parts of plasticizer (DOP)
Part, Valinium. Make a plastisol by mixing 3 parts of zinc-based composite stabilizer well, 7 parts of mixed chips or cut fibers such as 1 to 5 mm random length of beach, 3 ridges, etc., mica powder (flex) 50 to 300 microns. Thoroughly disperse 3 parts of the liquid, add 12 parts of bentonite as a gelling agent to thicken it, add 100 parts of china clay and 5 parts of titanium oxide, and use Ni-goo-roo-goo to coat the primed wallpaper with approx. .5-77L thickness and adhere.

This was treated with hot air at 135 to 140'C for 40 to 50 seconds to semi-gel (semi-melt), cool, and while continuing to cool, woven fabric, non-woven fabric, polyester film, etc.
It is made by simply overlapping one point of paper, etc. of f/d or higher, as if it were reinforced, and the two points of these sheet-like objects are held, and the distance between them is narrowed so that it can be moved or swung twice. Machine 2, for example, the Japanese Patent Publication No. 59-6953, performs the rolling process.

In this case, the vinyl sheet layer collapses and creates hexagonal cracks. Then, one layer of reinforcing paper is separated.

Next, this sheet-like material is heated for 30 to 40 seconds using a heating section such as a spreading machine, empossing machine, or foaming machine equipped with a far-infrared heater to partially remove cracks. The connections are melted and strengthened so that the overall appearance remains unchanged.

In this situation, the cracked area.

Cut fibers partially connect the cracks to create a bridge-like state, and mica powder and other substances are also exposed on the cross section, giving the dough a decorative effect.

Although the above is an example of implementation, the spread coating body has physical properties similar to those of plastic clay, putty, or caulking material in some respects.

As for the composition, the ingredients such as the main agent or binder include various synthetic resins, rubber-like substances that act as binders for natural products, resins, starches, and agar obtained from seaweed. and carrageenan can also be used.

In its use, the amount of binders may be smaller than that of tangible materials.

For example, in the case of an earthen wall, water and soil are made of straw cut into two dimensions, but the two binders are the cohesive components in the water and soil, and are less in proportion than the tangible or solid materials. In such a case, if the materials are carefully selected, it will be like the one shown in the example above, but it can be used as a water-soluble resin or emulsion instead of water, or as a substitute for soil.

Selection of soil itself or plastic moonlight agent 4
Extender pigments, china clay, etc. are used.

Decorative materials include coarse grains, granules, and flakes of synthetic resin pellets, cut colored films, mica, shell powder, pigments, and extender pigments, and fibrous materials include synthetic resins and flakes. Natural fibers can also be used from plants, animals, and agricultural products.

These sizes and shapes depend on the processing means, but the maximum size is not affected much by the thickness of the sheet-like material. For example, in the case of kneading, it is crushed or deformed, and in the case of flakes or fibers, the diameter may be less than the thickness, and the length may be any multiple of the thickness.

Next, regarding the processing method, in order to make a sheet-like product,
Coating methods, extrusion methods, calendar printing methods, spraying methods, etc. can be used.

To create partial cracks or cracks in this sheet-like material, processing methods such as beating, vibration, bending, and even kneading are generally used under appropriate temperature conditions.

Can be used at low temperatures below room temperature.

Hot air can also be used as external energy to strengthen these processed parts, but it is not necessary to heat the entire composition of the sheet-like material.

Rather, it is sufficient to melt specific components in the two compositions to connect them, or to strengthen the reaction.

Irradiation with ultraviolet rays, electron beams, infrared rays, etc. alone or separately.

It is effective to use it in combination with hot air.

As explained above, the main elements constituting this invention are:
Sort-like objects include tangible objects and substances that act as binders, and when they crack or crack due to beating or rolling, external energy is applied to connect and strengthen these parts. It consists of three points that strengthen the damaged area when given.

However, as a result of the above-mentioned processing, the cracks caused by the above-mentioned processing have resulted in the overall surface undulations becoming large and three-dimensional, such as unevenness and partial bulges, and tangible objects have appeared in the cracked areas, and other To bring out the parts more clearly, sanding, buffing, brushing, etc. can be performed as in the finishing process.

In the above, a sheet-like composition is formed as the top layer, but if this composition is extremely brittle, a plastic film may be laminated on top of the two compositions for reinforcement or decoration purposes, or a protective layer may be added. The initial objective can be achieved by performing subsequent processing after providing .

(g) Effects of the Invention Conventionally, sheet-like materials 1 such as vinyl leather, synthetic leather, vinyl wallpaper, etc., which deteriorate over time and crack due to deep drawing or composition, such as reptile or geometric patterns, are considered to be defective. was.

This invention is completely different from conventional ones. In other words, - we purposely construct a composition that is prone to cracks and crazing, which looks like a defective product, and force cracks and cracks to occur in the sort-like object by applying external force, and then strengthen it to put it into practical use. It was designed to withstand.

The sheet-like product formed in this way has tangible objects exposed, natural cracks and damage, giving a three-dimensional effect and decorativeness, which has not been seen before. becomes.
