Description

Technical Field

[0001] The present invention relates to a composite sheet-like material, and particularly to a low-temperature-rising soft composite sheet-like material and a low-temperature-rising soft seat including the low-temperature-rising soft composite sheet-like material.

Background Art

[0002] The material of the fabric on the seat surface of general means of transportation such as bicycles, motorcycles, boats, or automobiles, buses, etc. is a soft plastic, for example, polyvinyl chloride (PVC), polypropylene (PP), polyurethane (PU), polyethylene terephthalate (PET), nylon, etc.

[0003] Also, in order to make the dirt and reflected light on the seat surface less noticeable, usually, the color of the seat surface is a dark color. For example, carbon black, which is easily available and can be used as a pigment, is added to the plastic to be set to black.

[0004] The use of carbon black can reduce the visibility of dirt, but it has the disadvantages of absorbing infrared rays and significantly raising the temperature of the seat, and being difficult to cool down after the temperature has risen.

[0005] In recent years, as the summer heat has become more severe, the demand for seats of means of transportation with low-temperature-rising properties has also been increasing. Setting the color of the seat surface to a light color (especially white) can effectively reduce the temperature-rising effect due to infrared absorption, but dirt is more likely to be noticeable.

[0006] Patent Document 1 discloses an infrared low-temperature-rising pigment composition combining specific types of pigments in order to reduce the temperature-rising effect due to infrared absorption. However, there is still room for further improvement in its temperature-rising reduction effect.

[0031] A thin metal film 2 made of a low-temperature, flexible composite sheet material is tightly bonded to a fabric layer 3. [Examples]

[0032] The present invention will be described in more detail by the following embodiments, but it should be understood that these embodiments are illustrative and not limiting the implementation of the present invention.

[0033] Examples 1 to 10 According to the content ratios shown in Table 1 (assuming the total weight of the soft polymer thin film 1 is 100 wt%), the colorants were added to the pulverized PVC (used as thermoplastic polymer) granules and mixed (assuming the total weight of the PVC granules is 100 wt%, and the colorant content ratio is 20 wt% to 40 wt%).

[0034] Next, the color masterbatch compositions of Examples 1 to 10 were produced by extrusion and kneading using a twin-screw extruder at 150°C to 180°C.

[0035] After cutting the color masterbatch compositions of Examples 1 to 10 into granules, a PVC film (flexible polymer substrate, 0.35 mm thick) was added to each to color them, and the flexible polymer thin films 1 of Examples 1 to 10 (see Figure 1) were produced.

[0036] The color and transparency of the flexible polymer thin film 1 in Examples 1 to 10 are shown in Table 2.

[0037] The flexible polymer thin films 1 of Examples 1 to 10 were heated to 150°C, and metal thin films 2 (see Figure 1, thickness 0.8 μm) were bonded to one surface of each of the flexible polymer thin films 1 of Examples 1 to 10 according to Table 1, and the two thin films were tightly bonded to obtain the composite sheet-like materials of Examples 1 to 10 (see Figure 1). [Table 1] [Table 2]

[0038] Examples 11 and 12 The manufacturing processes for Examples 11 and 12 are similar to those for Examples 5 and 10, respectively. The difference is that the color masterbatch compositions for Examples 11 and 12 are manufactured based on the content ratios shown in Table 1, and after manufacturing the flexible polymer thin films 1 for Examples 11 and 12, aluminum is vacuum-deposited onto one side of the flexible polymer thin films 1 for Examples 11 and 12, respectively (the thickness of the aluminum deposition layer is approximately 0.2 μm).

[0039] As a result, the aluminum was tightly bonded to the soft polymer thin film 1, yielding the composite sheet-like materials of Examples 11 and 12. The color and transparency of the soft polymer thin film 1 of Examples 11 and 12 are shown in Table 2, respectively.

[0040] Examples 13 and 14 The manufacturing processes for Examples 13 and 14 are similar to those for Examples 5 and 10, respectively. The difference is that the color masterbatch compositions for Examples 13 and 14 are manufactured based on the content ratios shown in Table 1. After manufacturing the flexible polymer thin films 1 for Examples 13 and 14, an aluminum paste (containing 15% aluminum powder with an average particle size of approximately 600 nm, 37% polyvinyl chloride-vinyl acetate copolymer (PVCA) resin, 30% ethyl acetate, and 18% methyl ethyl ketone) is applied to one side of the flexible polymer thin films 1 for Examples 13 and 14, respectively (the thickness of the aluminum paste application is approximately 20 μm to 40 μm).

[0041] As a result, the aluminum paste was tightly adhered to the soft polymer thin film 1, yielding the composite sheet-like materials of Examples 13 and 14. The color and transparency of the soft polymer thin film 1 of Examples 13 and 14 are shown in Table 2, respectively.

[0042] Examples 15-17 The manufacturing processes for Examples 15 to 17 are similar to those for Examples 2 to 4, but the difference is that the color masterbatch compositions for Examples 15 to 17 were manufactured according to the content ratios shown in Table 3 (assuming the total weight of the flexible polymer thin film 1 is 100 wt%), and finally the composite sheet-like materials for Examples 15 to 17 were obtained. The color and transparency of the flexible polymer thin film 1 for Examples 15 to 17 are as shown in Table 2. [Table 3]

[0043] <Example of comparison> Titanium dioxide (1 wt% to 2 wt%, with the total weight of the soft polymer thin film being 100 wt%) was mixed with pulverized thermoplastic polymer particles, and the mixture was extruded and kneaded at 150°C to 180°C using a twin-screw extruder to produce a titanium dioxide color masterbatch composition.

[0044] After cutting the titanium dioxide color masterbatch composition into granules, a PVC film (0.35 mm thick) was added and colored to obtain a control example of a white sheet-like material (0% transparency).

[0045] <Comparative Example> A carbon black color masterbatch composition was produced by mixing 0.5 wt% to 1 wt% of carbon black (with a total weight of 100 wt% of the soft polymer thin film) with pulverized thermoplastic polymer particles and extruding and kneading the mixture at 150°C to 180°C using a twin-screw extruder.

[0046] After cutting the carbon black color masterbatch composition into granules, a PVC film (thickness 0.35 mm) was added and colored to obtain a comparative example of a black sheet-like material (transparency 0%).

[0047] <Test Example 1> Infrared Heating Test Table 4 shows the results of irradiating the composite sheet materials of Examples 1 to 17 (on the side without the metal thin film 2), the flexible polymer thin film 1 of Examples 1 to 17, the white sheet material of the control example, and the black sheet material of the comparative example with an infrared lamp (Philips PAR38 IR Red, 150W, 125V~130V, wavelength range 600nm~1400nm) at a distance of 25cm for 60 minutes at 26℃, and measuring the temperature of each with an infrared thermometer. [Table 4]

[0048] The results in Table 4 show that the temperatures of the composite sheet materials of Examples 1 to 17 of the present invention after absorbing infrared radiation for 60 minutes were all 78°C or lower. This is clearly lower than the temperature of the soft polymer thin film 1 of Examples 1 to 17 after absorbing infrared radiation for 60 minutes (83°C to 90°C), and is equivalent to or even lower than the temperature of the white sheet material of the control example after absorbing infrared radiation for 60 minutes (76°C).

[0049] On the other hand, the comparative example's black sheet-like material reached a temperature of 112°C after absorbing infrared radiation for 60 minutes, indicating a large temperature rise. This demonstrates that the low-temperature rise flexible composite sheet-like material of the present invention can reduce the temperature rise due to infrared radiation absorption.

[0050] <Test Example 2> Sunlight Temperature Increase Test At 11:00 AM (temperature approximately 37°C), the composite sheet materials of Examples 1 to 10 and Examples 15 to 17 (the side without the metal thin film 2), the soft polymer thin film 1 of Examples 1 to 10 and Examples 15 to 17, the white sheet material of the control example, and the black sheet material of the comparative example were exposed to direct sunlight outdoors for 60 minutes, and the results of measuring the temperature of each are shown in Table 5. [Table 5]

[0051] The results in Table 5 show that the temperatures of the composite sheet materials in Examples 1 to 10 and Examples 15 to 17 after 60 minutes of solar radiation were all 52°C or lower. This is clearly lower than the temperatures of the soft polymer thin films in Examples 1 to 10 and Examples 15 to 17 after 60 minutes of solar radiation (56°C to 64°C), and is almost the same as, and even lower than, the temperature of the control example white sheet material after 60 minutes of solar radiation (51°C).

[0052] On the other hand, the temperature of the comparative example black sheet material reached 83°C after 60 minutes of solar radiation, indicating a large temperature rise. This demonstrates that the low-temperature rise flexible composite sheet material of the present invention can reduce the temperature rise due to solar radiation.

[0053] <Application Example> Low-temperature flexible sheet The foam material layer 4 (see Figure 2) was tightly wrapped with the fabric layer 3 (see Figure 2) to obtain the sheet body.

[0054] One side of the composite sheet material having the metal thin film 2 of Examples 1 to 17 above was tightly bonded to the opposite side of the fabric layer 3 of the sheet body from the foam material layer 4 side using an adhesive, thereby tightly attaching the metal thin film 2 to the fabric layer 3 and obtaining the low-temperature flexible sheets of Application Examples 1 to 17 (see Figure 2).

[0055] <Example of comparative application> Flexible sheet A sheet body was obtained by tightly enclosing a foam material layer with a fabric layer. The white sheet-like material of the above control example was tightly bonded to the opposite side of the fabric layer of the sheet body from the foam material layer using an adhesive to obtain a flexible sheet of the control application example.

[0056] <Comparative Application Examples> Flexible Sheets A sheet body was obtained by tightly wrapping a foam material layer with a fabric layer. The black sheet-like material of the comparative example above was tightly bonded to the opposite side of the fabric layer of the sheet body from the foam material layer using an adhesive to obtain a flexible sheet of the comparative application example.

[0057] <Test Example 3> In-car temperature reduction test Between 10:00 AM and 12:00 PM (at an ambient temperature of approximately 36°C), the low-temperature rise flexible sheet of Application Example 7, the flexible sheet of the control application example, and the flexible sheet of the comparative application example were placed inside a car with the windows closed and the air conditioning turned off, with the sheet material facing upwards and the foam layer facing downwards, for 120 minutes. The temperature rose to approximately 72°C.

[0058] Then, with the car windows fully open and the air conditioner set to maximum fan speed and 18°C, the temperature of the soft sheet was measured every 30 seconds using an infrared thermometer, and the results are shown in Table 6. [Table 6]

[0059] The results in Table 6 show that all of the low-temperature rise flexible sheets in Application Example 7 of the present invention cooled to below 50°C within 90 seconds and to below 45°C within 180 seconds, indicating that the cooling rate is equivalent to that of the flexible sheet in the control application example. On the other hand, the flexible sheet in the comparative application example cooled to only 55°C within 90 seconds and to only 50°C within 180 seconds, indicating a low cooling rate. This demonstrates that the low-temperature rise flexible sheet of the present invention can effectively increase the cooling rate inside a vehicle.

[0060] According to the above, the low-temperature-rising flexible composite sheet material of the present invention reflects infrared rays or sunlight, thereby suppressing the rise in temperature caused by infrared rays or sunlight. This prevents further conduction of thermal energy into the foam of the low-temperature-rising flexible sheet, and when applied in an open space, it can prevent the continuous rise in temperature of the sheet (e.g., bicycle saddle, motorcycle seat, boat seat).

[0061] Furthermore, when applied to a sealed space, the rate of cooling of sheets (for example, car seats, bus seats) can be increased, and since users do not need to consume extra energy to lower the temperature of sheet-like materials or sheets, the objectives of the present invention can be reliably achieved.

[0062] The above embodiments are illustrative in illustrating the principles and effects of the present invention and do not limit it. Those skilled in the art can make some modifications and alterations to the above embodiments, provided they do not deviate from the spirit and scope of the invention. Therefore, all modifications and alterations made by those skilled in the art, provided they do not deviate from the spirit of the invention, should also be considered to fall within the scope of protection of the present invention. [Industrial applicability]

[0063] The low-temperature-rising, flexible composite sheet material of the present invention is suitable for installation on the sheets of various transport devices. [Explanation of symbols]
