Description
本發明係關於彈性粒狀物及其製造方法。此外，並關於使用該粒狀物之人工草坪、鋪設體、鋪設路與該等之製造方法。 The present invention relates to elastic granular materials and manufacturing methods thereof. In addition, it also relates to artificial turf, paving bodies, and paving roads using the granular materials and their manufacturing methods.
以往，於網球、足球、棒球、橄欖球、曲棍球、五人制足球、美式足球、田徑、高爾夫練習場等之運動設施中使用草坪，與天然草坪相比，由於管理容易，所以廣泛地使用人工草坪。然而，由於此人工草坪的衝擊吸收性能較天然草坪差，所以競賽者在長期間進行競賽下會引起膝關節的損傷，或是於跌倒等時會受到較大傷害。因此，近年來為了提高人工草坪的衝擊吸收性而採用於草簇(草堆)間填充粒體之人工草坪。例如於專利文獻1中揭示 有在植設於基材之草簇(草堆)間填充硬質粒體與軟質粒體之混合物之內容。該實施例中，具體而言係使用粒徑0.07~1.2mm的矽砂粒體作為硬質粒體，使用粒徑0.5~2.5mm的天然橡膠碎屑粒體作為軟質粒體。然而，如此填充於草簇(草堆)之粒體，雖然具有衝擊吸收性，但容易吸收太陽光，且由於在粒體的空隙間包含空氣而不易使吸收的熱逸散，所以人工草坪的表面溫度成為高溫而大幅損及競賽環境。 In the past, turf has been used in sports facilities such as tennis, football, baseball, rugby, hockey, futsal, American football, track and field, and golf driving ranges. Compared with natural grass, artificial turf is widely used because it is easier to manage. . However, since the impact absorption performance of this artificial turf is worse than that of natural turf, competitors may suffer knee joint injuries when competing for a long period of time, or may suffer greater injuries when they fall. Therefore, in recent years, in order to improve the impact absorption of artificial turf, artificial turf in which granules are filled between grass tufts (haystacks) has been adopted. For example, disclosed in Patent Document 1 There is a content of filling a mixture of hard granules and soft granules between the grass clusters (grass piles) planted on the base material. In this embodiment, specifically, silica sand particles with a particle size of 0.07 to 1.2 mm are used as the hard particles, and natural rubber crumb particles with a particle size of 0.5 to 2.5 mm are used as the soft particles. However, the granules filled in the grass tufts (haystacks) in this way have impact absorption properties, but they easily absorb sunlight, and because air is contained in the gaps between the granules, it is difficult for the absorbed heat to escape, so the artificial lawn is The surface temperature becomes high and greatly damages the competition environment.
因此，於專利文獻2中，於橡膠碎屑的粒體表面形成近紅外線反射層並配置在人工草坪的表面，藉此可確認即使人工草坪鋪設在受到太陽光等的輻射熱之場所，人工草坪的表面溫度亦可下降而不會使舒適性降低。該專利文獻中，作為所使用之近紅外線反射劑，記載有具備0.01~500μm的粒徑之TiO2、ZnO、ZnAl2O4等之金屬氧化物，或是將此等金屬氧化物被覆於雲母等之鱗片狀礦物者等之具有高亮度者。此外，於專利文獻3中，記載有將碳酸鈣及氧化鈦調配於熱塑性彈性體以形成真比重為1以上且日照反射率為60%以上之彈性粒狀體，並將此填充於人工草坪的草簇(草堆)間之內容。 Therefore, in Patent Document 2, a near-infrared reflective layer is formed on the surface of rubber crumb particles and placed on the surface of artificial turf. This confirms that even if the artificial turf is installed in a place that receives radiant heat such as sunlight, the artificial turf will Surface temperatures can also be reduced without compromising comfort. This patent document describes metal oxides such as TiO 2 , ZnO, and ZnAl 2 O 4 having a particle size of 0.01 to 500 μm as the near-infrared reflecting agent used, or coating these metal oxides on mica. Those with scaly minerals and those with high brightness. In addition, Patent Document 3 describes mixing calcium carbonate and titanium oxide with a thermoplastic elastomer to form elastic granular bodies with a true specific gravity of 1 or more and a solar reflectance of 60% or more, and filling the artificial turf with this. The contents between grass tufts (haystacks).

[發明所欲解決之課題][Problem to be solved by the invention]
前述先前技術中，由於在橡膠碎屑的表面或內部形成有具有高亮度之氧化鈦顏料等的近紅外線反射劑，雖然人工草坪的表面溫度不易上升，但仍有近紅外線反射劑容易從粒體表面剝離而使該效果降低之問題。此外，由於使用二氧化鈦顏料等之具有高亮度之白色顏料作為近紅外線反射劑，所以亦產生使可見光反射而使眩目程度增幅之問題。另一方面，當使用對廢棄汽車用輪胎或窗框廢橡膠等進行碎屑加工者作為橡膠碎屑時，由於調配黑色的碳黑等，即使形成近紅外線反射層亦會產生太陽光的吸收，因而亦有人工草坪之表面溫度的抑制不充分之問題。 [用以解決課題之手段]In the above-mentioned prior art, since a near-infrared reflective agent such as titanium oxide pigment with high brightness is formed on the surface or inside of the rubber crumbs, although the surface temperature of the artificial turf is not easy to rise, the near-infrared reflective agent is still easy to evaporate from the particles. The problem is that the effect is reduced due to surface peeling. In addition, since white pigments with high brightness such as titanium dioxide pigments are used as near-infrared reflectors, there is also a problem of reflecting visible light and increasing the degree of glare. On the other hand, when crumbs processed from discarded automobile tires or window frame scrap rubber are used as rubber crumbs, black carbon black, etc. is blended, so even if a near-infrared reflective layer is formed, sunlight will be absorbed. Therefore, there is also a problem of insufficient control of the surface temperature of artificial turf. [Means used to solve problems]

評估實施例及比較例中所得到之試樣的柔軟性、比重、低可見光反射性、黑色度、日照反射率、表面溫度之結果如第1表所示。柔軟性的評估是以指尖壓碎所製作之試樣並以該手部的觸感來判斷是否具有良好的柔軟性。比重是使用JIS K 7112的水中置換法來測定。低可見光反射性的評估是將試樣放置在室外的太陽光所照射之場所來觀察。黑色度是以CIE 1976 L*a*b*色空間的L*值來評估。日照反射率(波長780nm~2,500nm)是藉由與彈性粒狀物為同一組成之原料來製作薄片狀試樣，並使用島津製作所公司製的紫外線-可見光-近紅外線分光光度計UV-3150，以根據JIS A 5759之方法來測定。表面溫度的評估是將所製作之試樣120g放入於塑膠製的托盤(厚度1cm)，從上部47cm照射紅外線燈並測定經過60分鐘後的表面溫度。Table 1 shows the results of evaluating the softness, specific gravity, low visible light reflectivity, blackness, solar reflectance, and surface temperature of the samples obtained in the Examples and Comparative Examples. The softness is evaluated by crushing the prepared sample with fingertips and judging whether it has good softness by the touch of the hand. The specific gravity is measured using the water displacement method of JIS K 7112. To evaluate the low visible light reflectivity, place the sample outdoors in a place exposed to sunlight and observe it. Blackness is evaluated based on the L* value of the CIE 1976 L*a*b* color space. The solar reflectance (wavelength 780nm ~ 2,500nm) is measured by preparing a flake sample using the same raw material as the elastic granular material, and using the ultraviolet-visible-near-infrared spectrophotometer UV-3150 manufactured by Shimadzu Corporation. Measured according to the method of JIS A 5759. The surface temperature was evaluated by placing 120 g of the prepared sample on a plastic tray (thickness 1 cm), irradiating an infrared lamp from the top 47 cm, and measuring the surface temperature after 60 minutes.
實施例的試樣，可確認於該內部具有黑色紅外線反射無機顏料、擴展顏料。此外，如第1表所示，實施例的試樣具有良好的柔軟性與低可見光反射性，比重為0.9以上。可確認日照反射率、黑色度良好，表面溫度與比較例相比亦具有約10℃的溫度差。另一方面，可確認比較例1的日照反射率低，表面溫度亦增高。In the sample of the Example, it was confirmed that the interior contained a black infrared-reflecting inorganic pigment and an expanded pigment. In addition, as shown in Table 1, the samples of the Examples have good flexibility and low visible light reflectivity, and have a specific gravity of 0.9 or more. It was confirmed that the solar reflectance and blackness were good, and the surface temperature also had a temperature difference of about 10°C compared with the comparative example. On the other hand, it was confirmed that the solar reflectance of Comparative Example 1 was low and the surface temperature was also high.
人工草坪分別構成為200mm×130mm的四角形，於長草堆之人工草(材質：聚烯烴、草長：63mm)的草之間填充6號矽砂(用量：30kg/m2 )，於該上方填充實施例1、實施例2(用量：11kg/m2 )，以成為矽砂與橡膠碎屑的粒狀物之2層構造之方式來製作試樣。 評估實施例及比較例中所得到之人工草坪試樣的衝擊吸收性、低可見光反射性、表面溫度之結果如第2表所示。衝擊吸收性的評估是將所製作之試樣放置在空地然後踩踏，並以該觸感來判斷。低可見光反射性是將試樣放置在室外的太陽光所照射之場所來觀察。表面溫度的評估是將所製作之試樣放置在桌上，從上部47cm照射紅外線燈並測定經過60分鐘後的表面溫度。Artificial turf is constructed into a square shape of 200mm×130mm. No. 6 silica sand (amount: 30kg/m 2 ) is filled between the grasses of the long haystack of artificial grass (material: polyolefin, grass length: 63mm), and then filled on top. In Example 1 and Example 2 (amount: 11 kg/m 2 ), samples were prepared in a two-layer structure of granular materials of silica sand and rubber crumbs. The results of evaluating the impact absorption, low visible light reflectivity, and surface temperature of the artificial turf samples obtained in the Examples and Comparative Examples are shown in Table 2. To evaluate the impact absorption, place the prepared sample in an open space and then step on it, and judge based on the tactile feel. Low visible light reflectivity is observed by placing the sample outdoors in a place exposed to sunlight. The surface temperature was evaluated by placing the prepared sample on a table, irradiating an infrared lamp from 47cm above it, and measuring the surface temperature after 60 minutes.
[產業上之可應用性] [Industrial applicability]
本發明之彈性粒狀物，其紅外線反射性高，可充分地抑制採用此之人工草坪等之表面溫度的上升，同時由於是黑色而能夠抑制可見光的反射且由於比重大，可防止因風雨等所導致之飛散或流出、水浮起，所以可使用在人工草坪、鋪設體、鋪設路等之填充材料。The elastic granular material of the present invention has high infrared reflectivity, which can fully suppress the rise in surface temperature of artificial lawns using it. At the same time, because it is black, it can suppress the reflection of visible light, and because of its large specific gravity, it can prevent wind and rain, etc. It causes scattering or outflow and water floating, so it can be used as a filling material for artificial lawns, paving bodies, paving roads, etc.
