Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a mattress having excellent body pressure dispersibility and cushioning properties. [Prior Art] Conventionally, in a bedding such as a mattress, a resin foam excellent in body pressure dispersibility and comfortable to sleep is used, particularly a low resilience polyurethane foam. In recent years, in the ageing society, caregivers are gradually increasing in hospitals, elderly care institutions, and families. Most caregivers inevitably live in bed. Most of the beds used by such caregivers are made of a fiber cloth coated with a mattress made of hard cotton or resin foam. For example, in Patent Document 1, there is a mattress that is not used in a medical institution or a social welfare institution, and is particularly used in a bed for a caregiver. The mattress is coated on the surface of a core material with a low-strength urethane film. According to the mattress, the cushioning effect of the mattress is fully exerted by the movement of the surface portion of the mattress in accordance with the cushioning property of the core material. Further, in Patent Document 2, a bedding for use in hospitalized patients, elderly welfare institutions, and the like is disclosed. The bedding pad is formed by laminating a formic acid & According to the bedding (4), it is excellent in handleability and easy to get up. π In the mattress described in Patent Document 1, and the bedding treatment device and the elderly care facility described in Patent Document 2, various kinds of hiding for the bed of the caregiver bed are required. However, we have excellent mattresses. The object of the present invention is to provide a bed of the present invention. [Technical Problem to be Solved] The object of the present invention is to provide a bed of the present invention. Pad, which has excellent pressure dispersion and 201236667 in medical institutions and elderly care institutions, etc., because of the light weight, even if there is adhesion, it is easy to wipe off the labor of sultry, prevent acne, etc. Comfortable and restrainable [means for solving the problem] cotton, layer; the first-low rebound elasticity of the processing surface of the wheel temple 4 1; 00/i〇〇it52fh: 〇mm ', according to the structure Shiplin, which can alleviate the uncomfortable cause, etc. The mattress is especially suitable for the treatment institution, the old man's photo ^' lZlllZmTZn J to use the contour processing surface upwards, or by pressing the top = according to the composition, body pressure It is more excellent in dispersibility and can further alleviate the uncomfortableness. Preferably, the apparent density of the elastic layer of the elastomeric urethane foam layer of 2〇C=1 is preferably 45 to 4 201236667. This structure is low in density and high in hardness, and excellent in body pressure dispersion. 2, the sense of _. In addition, because the bed is light and light, it can be used to reduce the burden on caregivers if it is used in medical care and elderly care facilities. ', 存, ί, in the mattress, the first - high rebound elastic amine carboxylic acid ^ foam layer preferably has a tensile strength of 150 to 240 kPa, and the tear strength is preferably 7 to 12 N / en ^ according to the structure Even if contour processing is applied, the article can be formed. Therefore, even if the load is increased, it is possible to provide a durable mattress that is not easily damaged.

"" 层 The check of the layer 2 is also not fixed, but it is __2G to 6Gk_3, especially 30. The hardness of the first-low-rotation layer 2 is also not particularly limited, but the hardness at 40% constant compression measured by JIS K 6400-2 A _S0 2439) is preferably 45 to _/314 cm 2 , particularly preferably 5 〇 to 70 N. /314cm2. As long as the first-low rebound layer 2 is 2G to 6Gkg/m3 and its hardness is 45 to 80N/314cm2', excellent body pressure dispersibility can be obtained, and the uncomfortable feeling of lifting can be alleviated. Also, the mattress can be made lighter. The compressive residual strain of the first low rebound elastic layer 2 is also not particularly limited, but if it is to be made into a mattress which is difficult to deform, the method is JIS K 64〇〇_4 A (the test piece is compressed by 75%) (ISO 3385) The measured compressive residual strain is preferably from 4 8 to 8 〇 0 /. , especially good 4.5 to 7.0%. The repeated compression residual strain of the first low-elastic elastic layer 2 is not particularly limited as measured by the method of JIS K 6400-4 A (ISO 3385), but is preferably 2 Å or less, particularly preferably 1.5% or less (usually 0.5%). the above). The resin film layer 3 is formed by a resin film containing a synthetic resin. The synthetic resin may, for example, be a polyamine phthalate resin, a polyolefin resin, a polyester resin, a polyamide resin, or the like, but may be a urethane foam such as the first low rebound elastic layer 2 or the like. From the viewpoint of the adhesion of the cotton layer, a thermoplastic amino carboxylic acid vinegar resin film is preferred. As long as it is a thermoplastic urethane resin film, a solution type, an emulsion type or the like containing a polyurethane resin may be used, and if necessary, by heating and pressing, the amino decanoic acid may be used. The ester foam layer is easily and firmly bonded and laminated. Further, as long as it is a thermoplastic urethane resin film, the urethane foam layer can be easily and firmly bonded and laminated by frame lamination or thermal lamination. It is particularly preferable that when the mattress 100 of the present invention is used in a medical institution or a social welfare institution, the mattress 100 of the present invention is not full of moisture caused by sweating or the like. Therefore, if the entire mattress 100 has sufficient moisture permeability, the resin film layer 3 laminated on the surface of the first low 201236667 rebound elastic layer 2 must also have a predetermined moisture permeability. The moisture permeability of the resin film layer 3 measured by JIS Z 0208 (ISO 2528) condition B (temperature: 40 ± 0.5 ° C, relative humidity: 9 〇 ± 2%) is preferably from 1 〇〇〇 to 1500 g/m 2 · 24h. 'Specially good is 1〇5〇 to I400g/m2 · 24h, 1100 to 1300g/m2 · 24h. As described above, the resin film layer 3 has moisture permeability, but can suppress leakage of air and maintain air pressure. Therefore, the mattress is not filled with moisture. Further, excellent body pressure dispersibility can be obtained and sufficient cushioning properties can be obtained. The thickness of the resin film layer 3 is not particularly limited. If the resin film layer 3 has a sufficient cushioning property in addition to the above-mentioned moisture permeability, the thickness of the resin film layer 3 is preferably from 50 to 90 μm. It is 60 to 80 μm. When the thickness of the resin film layer 3 is 50 to 90 μm, the bed is not filled with moisture and has sufficient cushioning properties. Further, since the resin film layer 3 has sufficient strength, damage to the mattress can be suppressed. The other physical properties of the resin film layer 3 are not particularly limited, but the tensile enthalpy measured by JIS κ 7311 is preferably 45 to 9 GMPa, particularly preferably 60 to 80 MPa. 45 to 90 MPa, even if a load is applied, the resin film layer and the valley are bad. Therefore, the longevity of the bed can be mentioned. Further, the tensile elongation measured by jis κ 7311 is difficult to be 75 G%, and the county is 5 (8) to 7 %. The tear (four) degree measured by L $ ΙίΓ/ϋ7311 is preferably 5G to 9_/m, and particularly preferably 60 to 80 kN/m.

When the institution or the browning mechanism is used in a bed for the caregiver, the sanitary surface caused by fire, excretion, etc. ’ is better for right flammability and antibacterial properties. I wish that the mattress has a flame retardant which is difficult to be a bismuth oxide or a phosphate ester, and various flame retardants such as a phosphorus-based flame retardant such as aluminum hydroxide such as aluminum hydroxide 201236667 may be mentioned, and the viewpoint of the environment is considered. Preferably, the phosphate-free flame retardant is halogen-free. The antibacterial agent may, for example, be a silver-based boiling agent; or a various antibacterial agent such as a zeolite-based antibacterial agent or a dissociated silver dioxide dioxide gel such as a silica gel-based fungicide or a phosphoric acid-based antibacterial agent. The flame retardant and the antibacterial agent are only used alone or in combination of two or more. As shown in the first figure, the mattress 100 of the present invention is composed of a first high resilient elastic screen 1, a first low rebound elastic layer 2, and a domain fat film layer 3. According to the present & ampere, since only the three layers can have sufficient body pressure dispersibility and the like, it is possible to provide a mattress that is comfortable to sleep. In particular, when a medical institution or a social welfare institution is used for a mattress for a caregiver, it is necessary to have a better dispersibility of the bed and a more comfortable sleep. Therefore, as shown in the second figure, in addition to the above-mentioned two-screen mattress, it is preferable to have a second high rebound elastic amine group on the surface of the wheel _u pair; a sulphuric acid foam layer (hereinafter referred to as a 高 高 high rebound elastic layer) 4; a second low rebound elastic urethane foam layer on the second high elastic elastic layer 4 surface (hereinafter referred to as "Low rebound elastic layer") 5.

Next, the binder is dried to remove the medium. A spliced sheet of slab is joined to make a laminated sheet. Next, each of them is heated: two sides of the f-sheet; a joint surface of the foam sheet which becomes the first-low rebound elastic layer 2 and the foam sheet which becomes the second, back, elastic layer 5. Next, each of the foam sheets is laminated to be contacted by a pressurized field. Thus, a laminate including the first-high rebound elastic layer, the low-elastic elastic layer 2, the second high-elastic elastic layer 4, and the second low-elastic elastic layer 5 is produced. Apply a bonding agent to the entire surface, back surface and side surfaces of the laminate. Next, the binder is dried to remove the medium. Then, by extrusion molding, a thermoplastic urethane resin film having a thickness of 70 μm was extruded and adhered to the entire surface of the laminate to be heated. Next, the laminate and the resin film are joined to form a resin film layer 3. The moisture permeability of the film is as follows: vap〇r is 1200 g/m2 · 24 h, tensile strength is 72 MPa, tensile elongation is 600%, and tear strength is 68 kN/m. The mattress 2 of the second figure is placed on the test surface of a pressure measuring device (Vistamatic, model "fsa"). Next, on the mattress 200, the subject (male, 5 years old, height) 177cm, weight 7〇kg) lying on the bed. Then measured the body pressure distribution after the subject just lie down and after 15 minutes. On the mattress 2 with the first low rebound elastic layer 2 facing up The body pressure distribution of the subject in the state of lying on the bed is determined. The fourth figure shows the body pressure distribution immediately after lying down; the fifth figure shows the body pressure distribution after 15 minutes. Also, the second low rebound The body pressure distribution of the subject lying on the bed 201236667 is also measured on the mattress 2 on the elastic layer 5 facing upwards. The six figure shows the body pressure distribution after 15 minutes after the duck is lowered.

The sixth and seventh figures of age are on the flat bed facing up on the bed 200, until the discussion reaches iH77. After just lying down, I will see the body pressure and dare to the waist. π. Also, as shown in the large dot and oblique line of the seventh figure, after 15 15 201236667 points, it can be said that the body pressure is concentrated on the head, upper back and buttocks. As shown in the seventh figure, the small dot-shaped part and the large dot-shaped part;, the lower part: the waist part of the body-aged body is visible in the body: the person who has the excellent experience of the flat surface, which is especially suitable for one side. 'As shown in the oblique line part, the plaid part and the black part of the eighth figure, 'the prior art mattress using a hard cotton cloth, after the subject is seen, the loading and the buttocks are visible, and the system is a pressure needle on the buttocks. Also, no pressure is applied to t, and the waist is exposed to the burden of the face. Further, as shown by the oblique line portion and the checkered portion of the ninth figure, after 15 minutes, the pressure is concentrated to the head and the upper back, and on the one hand, there is almost no pressure applied to the waist. It can be seen that the previous body pressure dispersion of the mattress is worse than the present invention. Further, the fine 0_layer 3 is formed of a film containing a thermoplastic urethane resin. Money; IS L 19〇2 (IS. 3) was tested for its bacterial activity and evaluated. As a result, the strain had a bactenostatic activity value of 4.5, and in the case of Pseudomonas aeruginosa, Pseudomonas aeruginosa, and Staphylococcus aureus, the total activity of the bacteria was 5.0 or more. That is, it is extremely suitable for any of the strains to have a static activity value of 22 or more. Thus, it has excellent antibacterial properties.
