Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the improvement of various materials for construction, interior decoration, etc., which have improved cushioning properties, soundproofing properties, etc., by positively utilizing coconut fiber. It is about improvement.

[0002]

2. Description of the Related Art Generally, for example, as a building material,
Although there are various types, wood has been popular as a building material from the viewpoint of its humidity control function, easiness of processing, and the like because it gives comfort to people. However, wood has limitations in soundproofing, cushioning, vibration damping, etc.
With the recent increasing density of houses, housing complex, and high-class housing, it has become impossible to sufficiently cope with the soundproofing measures and antivibration measures of each house, which have been increasingly required. Therefore, at present, a floor board material is lined with a sound-absorbing and heat-insulating layer such as a felt layer for absorbing and cushioning or a honeycomb structure. In addition to such soundproofing measures and antivibration measures, the cushioning property is improved not only for building materials, but also for interior decoration such as floors and walls in transportation equipment such as vehicles, ships and airplanes, along roads, Sound barriers installed along railroad tracks, as well as packaging materials for high-quality products, are required.

On the other hand, materials used in these various fields have not only soundproofing and buffering properties, but also, in recent years, when structures made of these materials are discarded, they do not adversely affect the global environment and human environment. It is hoped that such consideration be given. However, among the various materials that have been provided so far, many materials that are excellent in soundproofing and cushioning properties are provided, but at the same time, the earth due to the generation of toxic gas, especially when heat-treated, is disposed of at the time of disposal. As for materials that have little impact on humans and the human body, the fact is that no particularly effective materials have been provided. In such a flow, in order to solve these problems at once, the present inventor has made a palm fiber by laminating a mat layer made of palm fiber with an adherend layer made of another material such as wood board. Regarding the used materials, it has already been technically provided (see Japanese Patent Laid-Open No. 5-177771).

[0004]

[Patent Document 1] This is a method of using palm fibers such as so-called palm skin and coconut mesocarp fiber, which have been conventionally used by paying attention only to the fact that they are natural fibers.
When matted, it has extremely excellent soundproofing, cushioning,
This is done by using palm fiber more positively than ever before, paying attention to the fact that it exhibits anti-vibration properties, heat insulation properties, suitable humidity properties, and eventually low pollution properties. However, this material using coconut fiber still has a drawback that it is low in fire resistance because it is a natural material, which should be improved. In particular, in recent years, various materials used in various fields are required to have not only soundproofing properties and cushioning properties but also sufficient flame retardancy. Even when considering the flame retardancy as described above, among the various materials, many are used under the condition of being exposed outdoors for a long time, for example, building materials, so It is necessary to give due consideration to the weather resistance and stability of action. However, in spite of the above high demands, it can be said that the present situation is that an effective material having all of them has not been provided.

An object of the present invention is to avoid the above-mentioned drawbacks and to provide an effective material having soundproofing property, cushioning property and the like, and at the same time having excellent flame retardancy, especially weather resistance and flame retardancy of its flame retarding action. The purpose is to provide a material that utilizes coconut fiber that takes into consideration stabilization.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described in detail. FIG. 1 and FIG.
The coconut fiber utilization material 10 is composed of a mat layer 14 formed from coconut fibers 12.

The palm fiber 12 is a fibrous bark collected from a plant of the family Palmaceae distributed in tropical and subtropical regions,
Fibers such as petiole base fiber and mesocarp fiber. The plant of the palm family is an evergreen shrub or tree, and its trunk has a single trunk without branching and has a crown at the tip. Some of them have almost no trunk, some can reach a height of 30 m, some have a smooth surface, and some are densely wrapped in old leaf sheaths. In addition, there are some species such as tows that climb up high on the tree as a vine, the ones in which the trunk bulges like a cone, and the exceptional ones that branch into two branches, such as the genus Hyphaene.

The leaves of these palmaceous plants are usually large, palm-like or feather-like, and the base of the leathery, petiole forms a wide leaf sheath to hold the trunk firmly. There are many fibers in this leaf sheath, and depending on the type, when old, the soft tissue rots and only this fiber remains, so-called palm skin. The inflorescences are well-branched in large inflorescences of apical or ephemeral, and in the case of apical, the flowers die when the flowers bloom. Fertilized by wind or insects, the fruits are berries or drupes, in which case the endocarp is usually attached to the seed and the mesocarp has a thick fiber layer.

The fiber produced in nature as described above is the palm fiber 12, and in the present invention, the bark, petiole base and mesocarp of this palm family plant are mechanically crushed or cut. The coconut fiber 12 collected by the above can be used. In addition, as for the plant of the family of the palm family that provides the palm fiber 12, specifically, (1) palms and palms can be mentioned as those in which the bark is present in a fibrous form, and (2) fibers are added to the petiole base. Examples thereof include Chamaelops genus Chabotou, Toddy palm peafowl, Scutellaria scutellaria, Scutellaria scutellaria, Date palm genus Date palm, Sago palm sago palm, Black claw syrup, Sugar palm, and (3) Coco palm as a medium skin fiber. Examples thereof include genus Coco palm, Nippa palm genus Nippa palm and the like.

As shown in FIGS. 1 and 2, the palm fiber 12 forms a mat layer 14 by being entwined in a non-woven fabric-like or three-dimensional network form. Specifically, after the palm fibers 12 collected by cutting or the like are once loosened, they are mechanically entangled by a needle punch or the like, a mechanical bonding method, an adhesive method, a spunbonding method, or the like, like ordinary nonwoven fabrics made of synthetic fibers. The mat layer 14 is formed by intertwining by various methods. Particularly, when the palm fibers 12 are entangled with each other, an adhesive is applied to the mat layer 14
Is desirable to have a proper strength.

In addition, after the coconut fibers 12 are entangled in a nonwoven fabric-like or three-dimensional network structure in this manner, the dense mat layer 14 is further pressed or hot pressed.
Is desirable. The thickness of the mat layer 14 is considered to be easy to use when it is normally set to about 5 mm to 20 mm, but the thickness is not limited to this, and depending on the application, for example, when used as a sheet material or a cushion material,
The thickness can be made thicker than that, or can be set to an appropriate thickness such as by stacking. When the coconut fiber 12 is thus formed into the mat layer 14, it has various performances required for the material such as excellent soundproofing property, cushioning property, vibration-proofing property, heat insulating property, and appropriate humidity due to its porosity.

A flame retardant agent 16 is attached to the mat layer 14 as shown in FIGS. Therefore, the mat layer 14 made of the palm fiber 12 has a soundproof property, a cushioning property,
While maintaining excellent performance as a material such as anti-vibration property, it is also possible to deal with flame retardancy which is a problem at the time of fire or the like.

As the flame retardant 16, a mixture of a flame retardant containing an organic phosphorus compound as a main component and a fixing agent containing a melamine resin as a main component is mixed with a curing accelerator containing an acidic substance as a main component. The flame retardant 16 is used. Among them, the organic phosphorus compound is, for example, water-soluble 3- (dialkylphosphono) propionamide, particularly 3- (dimethylphosphono) propionamide, and the melamine resin is, for example, water-soluble methylated hexamethylolmelamine. It is desirable to use hydrochloric acid as the acidic substance. The flame retardant 16 is used at an appropriate pH value, preferably a pH value of 3.0 or less by mixing a curing accelerator for an acidic substance with a mixed solution of the above flame retardant and a fixing agent.

More specifically, it is desirable to use the product name "Roof-proof" of Dainippon Ink and Chemicals, Inc. as the flame retardant 16. This "roof-proof" has an appropriate concentration with the product name "roof-proof P" as a flame retardant of the above-mentioned organic phosphorus compound and the product name "roof-pull-fix" as a melamine resin adhesive. The compounded liquid is mixed with the trade name "Catalyst X" as a curing accelerator for acidic substances. The "roof-proof" foams when heated to form a black carbonized heat insulating layer, which significantly delays the combustion of the mat layer 14 made of the coconut fiber 12 and imparts flame retardancy to the mat layer 14.

In particular, when this "roof-proof" from Dainippon Ink and Chemicals, Inc. is used, each of the components is chemically stable, so that even under adverse weather conditions such as rain,
Since the flame-retardant component does not elute from the mat layer 14, the weather resistance of the flame-retardant action is improved, and the flame-retardant property does not decrease,
desirable. It is most advantageous to use this "roof-proof" because it can be easily attached to the mat layer 14 by coating or dipping and has weather resistance. When a component other than "roof-proof P", for example, a flame retardant containing a methylol group such as N-methylol 3- (dimethylphosphono) propionamide or dimethylol 3- (dimethylphosphono) propionamide is used as the flame retardant It has been confirmed by experiments that they do not have sufficient weather resistance.

When ammonium polyphosphate microencapsulated with an epoxy resin is added to the above "roof-proof", it is possible to prevent undesired gloss from occurring on the coated surface of the "roof-proof". In addition, it is possible to prevent deterioration of flame resistance and weather resistance due to cracking of the coating film, which is preferable.

Further, an inorganic compound such as titanium carbide or tungsten carbide may be added to the above "roof-proof". This inorganic compound strongly chemically bonds with the Lewis acid component formed by heating the organic phosphorus compound and the nitrogen or the like constituting the melamine resin, and forms an extremely dense carbonized heat insulating layer. The foamed heat-insulating layer formed by 16 can be prevented from falling off from the mat layer 14 due to a low density and airflow such as hot air, and the flame retardancy can be further stabilized.

As long as it does not affect the flame retardancy of the "roof-proof", or the weather resistance and stability of its flame retardant action, it is used as a penetrant, an antifoaming agent, a crack preventing agent, and a coloring agent. Various other additives such as acid resistant pigments, fragrances, and odor inhibitors may be added.

The flame retardant 16, especially "roof-proof", and the flame retardant 16 obtained by adding other components thereto.
Can be attached to the mat layer 14 by coating.
Specifically, it is applied by a spray gun, a brush, a hand roll, a flow coater, a roll coater or the like and attached to the mat layer 14.

The flame retardant 16 is impregnated into the mat layer 14 as shown in FIG. 1 to bond the coconut fiber 12 as a binder to adhere to the mat layer 14 as shown in FIG. be able to. As described above, the mat layer 14 is formed by intertwining the palm fibers 12 by an appropriate method. The above-mentioned "roof-proof" has flame retardancy and at the same time has excellent adhesiveness to wood. Therefore, this "roof-proof" can impart flame retardancy to the mat layer 14 and at the same time can be used as a bonding means for the mat layer 14. In particular, in this case, the palm fiber 12 can be firmly adhered by "roof-proof" to give the mat layer 14 an appropriate strength required as a material.

In this case, in the "roof-proof", the condensation reaction proceeds with the passage of time, and after passing through the gel state, it becomes a dry state in several hours to form a transparent film, and further, in several days, It hardens completely and becomes insoluble in water. Therefore, specifically, after immersing the coconut fiber 12 in a water-soluble "roof-proof" which is the flame retardant 16, the coconut fiber 12 is left to stand for several days and then dried at room temperature. The "roof-proof" adhesiveness enables the mat layer 14 to be firmly adhered and formed. Depending on the situation, the coating film may not be left for several days after being dried, but may be forcedly dried by an electric heating type warm air heater or the like to be rapidly insolubilized.

As another example of the flame retardant 16, as shown in FIG. 2, a sheet-shaped flame retardant formed by combining a flame retardant containing an organic phosphorus compound and an inorganic or non-melting fiber woven fabric. It is also possible to use the burning agent 16. Examples of the flame retardant containing the organic phosphorus compound include melamine resin and 3-
It is preferable to use an aqueous solution in which (dimethylphosphono) propionamide is mixed, to which an acidic curing catalyst is added so that the pH value becomes 2.0 to 3.0, that is, the above-mentioned "roof-proof" or the like. it can. Further, as the inorganic or non-melting fiber woven fabric, for example, a glass fiber woven fabric, a carbonized fiber woven fabric, a metal fiber woven fabric, a carbonized fiber woven fabric, an oxidized acrylic fiber woven fabric, or the like can be used.

More specifically, the product name "Dick Frith" manufactured by Dainippon Ink and Chemicals, Inc. is used as the sheet-shaped flame retardant 16. This "Dick Frith"
2 is characterized in that it is a black mesh sheet formed mainly of phosphorus-based flame retardant 18 and glass cloth 20, as shown in FIG. "Dick Frith" is a phosphorus-based flame retardant 18 attached to the glass cloth 20 when heated.
Foams to form a black carbonized heat insulating layer, which significantly retards the combustion of the mat layer 14 made of the coconut fiber 12 and imparts flame retardancy to the mat layer 14.

Particularly, in this "Dick Frith" from Dainippon Ink and Chemicals, Inc., since the phosphorus-based flame retardant 18 is carried on the glass cloth 20, the surface layer of the flame-retardant material is exposed to the hot air flow during combustion. It is desirable because it is possible to prevent the carbonized heat insulating layer from being dropped off at the same time as the carbonized material is shrunk or the carbides are dropped off, and stable flame retardancy can be exhibited. This is because the glass cloth 20 retains its form even at a high temperature of about 1000 ° C. although its strength decreases and becomes brittle. In particular, in this case, each fiber constituting the glass cloth 20 is protected by the foamed carbonized heat insulating layer, so that the glass cloth 20 is only partially melted, and the melted part of the glass cloth 20 is carbonized thermally. Since it adheres to the layer and acts as a protective layer on the surface of the carbonized heat insulating layer, the phosphorus-based flame retardant 18 does not fall off, and therefore the flame retardant action does not decrease.

Further, when "Dick Frith" is used, the phosphorus-based flame retardant 18 also has adhesiveness at the same time. Therefore, by laminating this "Dick Frith", it is used as an intermediate adhesive layer between the mat layer 14 and another wood. There is also an advantage that can be. Furthermore, since it is a sheet, by using other appropriate bonding means such as an adhesive, other members such as a metal plate can be
By being laminated on the mat layer 14, flame retardancy can be imparted while ensuring soundproofing properties, cushioning properties and the like.

The sheet-shaped flame retardant 16, especially "Dick Friis", can be attached to the mat layer 14 by being laminated on the surface of the mat layer 14, as shown in FIG. Specifically, it can be easily laminated on the mat layer 14 by bringing it into close contact with the surface of the mat layer 14 with an epoxy resin, an adhesive, a tacker, or the like.

Since the phosphorus-based flame retardant 18 has adhesiveness as described above, the sheet-shaped flame retardant 16 is applied to the surface of the mat layer 14 after the phosphorus-based flame retardant 18 is applied. The glass layer 20 is covered, and the phosphorus-based flame retardant 18 is applied on the upper surface of the glass cloth 20 to form a sheet of the flame retardant 16 by permeating the same, and at the same time, the mat layer 1 is formed.
4 may be laminated.

Next, another embodiment of the present invention will be described with reference to FIG.
In this embodiment, the mat layer 14 has a layer 2 made of a material other than the coconut fiber 12.
Two are stacked. By laminating the adherend layer 22 made of another material on the mat layer 14 in this manner, the coconut fiber utilization material 10 of the present invention can be used as a building material, etc. while having a soundproofing property and a cushioning property and at the same time being flame retardant. It can be effectively used as a material in various fields required to have. Further, the adherend layer 22 serves as a surface layer without exposing the palm fiber 12 to the outside, and the appearance is not impaired.

The adherend layer 22 can be laminated on the mat layer 14 by adhering it to the surface of the mat layer 14 by using an appropriate adhesive means such as an adhesive. Further, since the flame retardant 16 used in the present invention has adhesiveness as described above, as shown in FIGS. 3 and 4, the flame retardant 16 is applied to the mat layer 14 to impart flame retardancy. At the same time, it can be used as a means for adhering the mat layer 14 and the adherend layer 22. More specifically, as shown in FIG. 3, the mat layer 14 and the adherend layer 22 may be directly adhered and laminated with a water-soluble flame retardant 16, or as shown in FIG. As shown, the mat layer 14 and the adherend layer 22 may be indirectly bonded and laminated via the sheet-shaped flame retardant agent 16. In this case, depending on the material of the adherend layer 22, the flame retardant 1
If the flame-retardant agent 16 is difficult to bond with the flame-retardant agent 16 alone, it is possible to apply an adhesive or the like to the surface of the sheet-shaped flame-retardant agent 16 to form the mat layer 1
It goes without saying that 4 and the adherend layer 22 may be laminated.

As the adherend layer 22, for example, a plate body 24 as shown in FIGS. 5 to 7 or a thin film body 26 as shown in FIGS. 8 and 9 can be used.

The plate 24 may be a wood plate 24A such as a plywood plate as shown in FIG. According to this aspect, the coconut fiber utilization material 10 of the present invention can be effectively used by imparting various performances to building materials such as floor boards and wall boards. In particular, it is possible to sufficiently meet the demand for excellent flame retardancy as well as soundproofness, cushioning properties, etc., which have been increasing for building materials in recent years. In particular, the material 10 utilizing coconut fiber of the present invention has weather resistance of flame retardant action and stability, and therefore is suitable even when used by being exposed outdoors.

Further, the plate 24 may be a metal plate 24B as shown in FIG. This metal plate 2
The coconut fiber utilization material 10 having 4B can be used as an outer wall plate, a soundproof wall, an inner wall of a boiler housing, or the like. In particular, since the coconut fiber 12 constituting the mat layer 14 is lightweight, it can be used as a material for the housing of an elevator. In particular, in order to secure safety in case of fire etc. at the same time as cushioning and soundproofing, It is suitable as a material for an elevator casing that is required to have flame retardancy. When the metal plate 24B is used as described above, the metal plate 24B is, as described above, the water-soluble flame retardant 1
Since it may be difficult to laminate 6 on the mat layer 14 as an adhesive means, as shown in FIG. 6, it is laminated on the mat layer 14 with the adhesive 28 via the sheet-like flame retardant 16. Alternatively, when the water-soluble flame retardant 16 is used, it is considered preferable to directly laminate it to the mat layer 14 with the adhesive 28.

Further, the plate 24 can be a corrugated cardboard 24C as shown in FIG. According to this aspect, the coconut fiber utilization material 10 of the present invention can be effectively utilized as a packaging material. In particular, along with the sophistication of products, it is gradually required that the packaging materials also have cushioning properties, vibration damping properties, etc., and flame retardancy to protect the products from accidental fire during transportation, storage, etc. Meanwhile, the coconut fiber utilization material 10 of the present invention can sufficiently meet such requirements. In addition, cardboard 24
When C is laminated, as shown in FIG. 7 (A), it may be laminated on the mat layer 14 by adhering it to the surface of the mat layer 14 in the liner portion 30 of the corrugated board 24C,
Further, as shown in FIG. 7B, it may be laminated on the mat layer 14 by adhering to the surface of the mat layer 14 at the top of the core 32.

Other than the plate 24, ceramics, gypsum board, concrete board, styrene mat, plastic plate, villous mat, carpet, foam layer of urethane, artificial leather, and further fiber dregs and boro felt It is possible to use a material that is relatively thick and hard or has a certain degree of shape-retaining property, such as an aggregate material. For example, a gathering material such as fiber meal or boro felt may be applied to the deposition layer 22.
The coconut fiber utilization material 10 laminated as above is suitable as an interior material for an automobile or an interior material for a trunk. In addition, the palm fiber utilizing material 10 in which plate bodies 24 are laminated as the adherend layer 22
, Other materials for filling the vehicle bumper, seats,
It can be effectively used as an interior material for transportation equipment such as ceilings, floors, doors, and front panels, and also as a material for soundproof walls, helmets, insoles, and the like.

Next, the case where the adherend layer 22 is the thin film body 26 will be described. In the present invention, the thin film body 26 is a general term for thin materials that do not have sufficient shape retention by themselves. Examples include paper, foil, film, cloth and the like.

The thin film body 26 may be a wallpaper 26A made of Japanese paper, for example, as shown in FIG.
When the wallpaper 26A and the like are laminated on the mat layer 14 in this manner,
The coconut fiber utilization material 10 of the present invention can be used as a building material for interior decoration.

Further, as shown in FIG. 9, the thin film body 26 may be, for example, a plastic film 26B, and the plastic film 26B is developed, for example, by Novamont Co., which belongs to Montedison Group of Italy. The brand name "Matterby" (registered trademark), which is a new thermoplastic film, can be used. This "Matterby" is biodegradable by absorbing water and swelling, and exhibits biodegradability almost equal to that of paper in an environment in which microorganisms survive. It is desirable because it does not adversely affect the global environment in combination with pollution.

As the thin film 26, other vinyl chloride film, polyester film, nylon film, aluminum foil, gold foil, cloth (for example, pillow, etc.) can be used. By laminating the thin film bodies 26 of various materials on the mat layer in this manner, the coconut fiber utilizing material 10 of the present invention is an effective material in various fields in which flame retardancy is required at the same time as soundproofing, cushioning, etc. Can be widely used as.

In each of the embodiments shown in FIGS. 1 to 9, these adhered layers 22 are laminated only on one side of the mat layer 14, but as shown in FIG. 10, they are laminated on both sides of the mat layer 14. Alternatively, as shown in FIG. 11, they may be sandwiched between a plurality of mat layers 14 to form a sandwich, so that they are laminated.

The flame retardant 16 can be attached not only to the mat layer 14 made of the coconut fiber 12 but also to the adherend layer 22. Thereby, the flame retardancy of the material 10 using palm fiber can be further improved. In this case, the adhering layer 22 to which the flame retardant 16 has been attached in advance may be laminated on the mat layer 14, or after the adhering layer 22 is laminated on the mat layer 14, the above-mentioned adhering layer 22 is formed. The flame retardant 16 may be attached by any suitable method described above.

Depending on the material of the adherend layer 22, it may be difficult to attach the flame retardant 16 because of its low affinity with the water-soluble flame retardant 16. Therefore, for example, the adhered layer 22
5 is a wood board 24A as shown in FIG. 5, both a water-soluble flame retardant such as "roof-proof" and a sheet-like flame retardant 16 such as "Dick Frith" can be used. However, for example, when the metal plate 24B or the plastic plate shown in FIG. 6 is used as the adherend layer 22, the metal plate 24B, the plastic plate or the like serves as a water-soluble flame retardant 16 such as "roof-proof". Since it has a low affinity and is difficult to adhere to them by coating or the like, it is preferable that the sheet-shaped flame retardant agent 16 such as "Dick Frith" is adhered to the surface with an adhesive to make it flame-retardant. it is conceivable that. When the flame retardant 16 is adhered to the adherend layer 22 as described above, it is desirable to sufficiently consider the material.

Finally, another example of the mat layer 14 will be described. Although the mat layer 14 is formed in a flat shape having a uniform thickness in the examples shown in FIGS. 1 to 11, the mat layer 14 is not necessarily limited to this. It is not something, depending on the application
As shown in FIG. 12, the surface may be embossed to form the unevenness 34, or may have a tapered shape instead of a uniform thickness.

Further, the mat layer 14 does not necessarily have to be formed only from the palm fiber 12, and the palm fiber 12 is made of fine synthetic resin fiber such as nylon, vinylon, vinyliderin, urethane, polyethylene, polypropylene, acrylic, etc. You may form intertwined. In this case, as long as it does not affect the properties of the flame retardant used in the present invention, if necessary, agents such as deodorant, fragrance, antibacterial agent, insect repellent, insect repellent, insecticide, etc. may be added to the synthetic resin fiber. Can be mixed in.

It should be noted that, for example, a viscoelastic substance such as silicone gel or polybudazidiene gel is coated on the coconut fibers 12 constituting the mat layer 14, or these viscoelastic substances are applied to the mat layer 12 or the adherend layer 22. It can also be laminated.
Thereby, the mat layer 14 made of the coconut fiber 12 can exhibit flame retardancy while further improving the soundproofing property, the cushioning property, the sound absorbing property, and the vibration damping property, so that the material can be more effectively used as a material. it can.
