Description
技术领域Technical field
本发明涉及一种体育运动场用环保型铺面材料，特别是一种不含高毒性的甲苯二异氰酸酯，不含重金属催化剂的环保型体育运动场用铺面材料。The invention relates to an environment-friendly paving material for sports fields, in particular to an environment-friendly paving material for sports fields that does not contain highly toxic toluene diisocyanate and heavy metal catalysts.
背景技术 Background technique
聚氨酯橡胶运动场(简称塑胶运动场)具有优良的耐磨、耐油、耐天候老化性、弹性适宜、吸震性能优良、硬度范围宽、平整、防滑、色彩美观、并且不受气候条件影响等优点，深受大众欢迎，也是现代体育运动场地(聚氨酯塑胶跑道、塑胶网球场、塑胶篮球场、塑胶羽毛球场、塑胶乒乓球场等)建设的发展方向。Polyurethane rubber sports field (referred to as plastic sports field) has the advantages of excellent wear resistance, oil resistance, weather aging resistance, suitable elasticity, excellent shock absorption performance, wide hardness range, flatness, non-slip, beautiful color, and is not affected by climate conditions. It is welcomed by the public and is also the development direction of the construction of modern sports venues (polyurethane plastic track, plastic tennis court, plastic basketball court, plastic badminton court, plastic table tennis court, etc.).
但是长期以来，在其生产中需要使用甲苯二异氰酸酯(TDI，有二种异构体)，而TDI是易发挥的有毒化学品，易与蛋白质结合，吸入高浓度的TDI蒸气会引起支气管炎、肺炎和肺水肿；长时间接触后，也会引起肝脏病变；接触液体可导致皮肤及眼睛永久性损伤。其LD50(口入半数致死剂量)为5.8g/kg，TLV(毒性反应最低极限值)为0.14mg/m3，在车间空气中最高容许浓度0.2mg/m3(卫生部颁标准TJ36-79)。But for a long time, it needs to use toluene diisocyanate (TDI, has two kinds of isomers) in its production, and TDI is easy to play toxic chemicals, easy to combine with protein, inhalation of high concentration of TDI vapor can cause bronchitis, Pneumonia and pulmonary edema; prolonged exposure can also cause liver disease; liquid contact can cause permanent damage to the skin and eyes. Its LD 50 (half lethal dose by mouth) is 5.8g/kg, TLV (lower limit value of toxic reaction) is 0.14mg/m 3 , and the maximum allowable concentration in the workshop air is 0.2mg/m 3 (Standard TJ36- 79).
另外，在其施工中需要加入铅催干剂加速聚氨酯的干燥，并提高其性能。据估计，2001年全国塑胶运动场(含塑胶跑道、塑胶篮球场、塑胶网球场等)铺设面积约700万m2，所需铅催干剂约448万Kg，相当于已铺设的塑胶运动材料中每公斤含铅量为1340mg。而铅是一种累积性毒物，具有渗透性，能引起急慢性中毒。现行国家标准GB15618-1995(土壤环境质量标准)中规定一级、二级、三级土壤环境质量标准分别为每公斤土壤中含铅量不大于35、300、500mg，而目前所铺设的塑胶运动场中铅含量超过此国际三个级别标准值分别为：38倍、4.5倍、2.7倍，其所造成的环境铅污染及其对人们健康的危害是不容忽视的。另外，汞的危害是不言而喻的。In addition, lead drier needs to be added in its construction to accelerate the drying of polyurethane and improve its performance. It is estimated that in 2001, the laying area of national plastic sports fields (including plastic track, plastic basketball court, plastic tennis court, etc.) was about 7 million m 2 , and the required lead drier was about 4.48 million Kg, equivalent to the laid plastic sports materials. The lead content per kilogram is 1340mg. Lead is a cumulative poison with permeability and can cause acute and chronic poisoning. The current national standard GB15618-1995 (Soil Environmental Quality Standard) stipulates that the first-level, second-level, and third-level soil environmental quality standards are respectively no more than 35, 300, and 500 mg of lead per kilogram of soil. The lead content in the medium exceeds the three international standard values respectively: 38 times, 4.5 times, 2.7 times, the environmental lead pollution caused by it and the harm to people's health cannot be ignored. In addition, the harm of mercury is self-evident.
