Description
技术领域
本申请涉及运动器材的领域,尤其是涉及一种应用PU连续发泡新材料的瑜伽垫。
背景技术
瑜伽垫最初是瑜伽运动者所使用的一种运动垫,为了降低身体与地面之间的碰撞,将瑜伽垫平铺至地面上,瑜伽运动者在瑜伽垫上进行瑜伽运动。而随着时间的推移,瑜伽垫的应用范围也大大增大,目前但凡是室内运动大多会在瑜伽垫上进行,瑜伽垫的柔软性,能够大幅降低运动者与地面的碰撞,并且吸收运动者在运动过程中产生的噪音。
目前由于大环境的影响,一些运动爱好者会选择在室内进行运动,为了减少室内运动产生的噪音以及提高运动舒适性,运动爱好者通常会选择在瑜伽垫上进行运动,也大大拓宽了瑜伽垫的使用范围。
针对上述相关技术,发明人认为在生产瑜伽垫时,将发泡物质放置于发泡模具中发泡成型,脱模后,得到成品;在模具中发泡对发泡物质的发泡效率具有较大限制,并且脱模过程中较易损坏产品,进而导致瑜伽垫的抗撕裂效果不佳。
发明内容
为了改善发泡物质的发泡效率低,成品易损坏、瑜伽垫抗撕裂效果不佳的缺陷,本申请提供一种应用PU连续发泡新材料的瑜伽垫,采用如下的技术方案:
一种应用PU连续发泡新材料的瑜伽垫,所述瑜伽垫包括发泡层和抗撕裂层,所述抗撕裂层位于发泡层之间,所述发泡层由包括发泡材料组成,所述发泡材料包括如下重量份物质:A料:聚醚多元醇50-60份、聚酯多元醇 20-30份、10-20份酚胺基多元醇;B料:多亚甲基多苯基多异氰酸酯、非离子型多异氰酸酯、二苯基甲烷二异氰酸酯或者甲苯二异氰酸酯中的任意一种;
所述发泡材料的制备包括如下步骤:(1)配料:A料与B料混合配料;(2)搅拌:将A料泵入混合器内,向混合器内通入氮气,然后加入B料,均匀搅拌,得到混合物料;(3)去湿:将混合器的温度调节至95-105℃,保持0.5-1h,降温至50-55℃,得到去湿的混合物料;(4)上料:将去湿后的混合物料上料至发泡载体上,利用刮刀将混合物料刮平;(5)发泡:将发泡载体上的混合物料运送至发泡炉内,发泡温度为150-180℃;(6)剥离:发泡完成后,分别对发泡载体、发泡产品进行收卷;(7)裁切,得到发泡产品。
通过采用上述技术方案,本申请技术方案优选采用聚醚多元醇、聚酯多元醇以及酚胺基多元醇配合作为A料,首先,A料中各组分之间的相容性较佳,因此在发泡形成瑜伽垫时,能够均匀提高瑜伽垫的抗撕裂效果以及弹性。而且,本申请在制备瑜伽垫时,能够连续进行发泡,发泡效果佳,对发泡产品的影响较小。
其次,本申请技术方案在A料中增加了酚胺基多元醇,由于酚胺基多元醇中的叔胺基集团,能够催化羟基与异氰酸基进行交联聚合,使得酚胺基多元醇获得了优异的自催化发泡的效果,并且能够协调发泡反应以及胶凝反应的平衡,得到泡孔均匀且交联致密的高强瑜伽垫,有效提高了瑜伽垫的抗撕裂效果。
最后,本申请技术方案中优化了制备工艺中的发泡温度以及去湿温度,在适宜的发泡温度下,能够使A料与B料之间充分反应,调控反应速度,使得发泡材料获得较佳的致密的交联结构,进一步提高瑜伽垫的抗撕裂效果。
此外,通过抗撕裂层的加入,由于发泡材料与抗撕裂层之间的结合效果较佳,因此能够抗撕裂层有效增强瑜伽垫的抗撕裂效果。
优选的,所述酚胺基多元醇的制备包括以下制备步骤:按重量份数计,取10-11份腰果酚、31-32份环氧氯丙烷、0.1-0.15份苄基三乙基氯化铵、1.0-1.5份氢氧化钠、2-3份二乙醇胺、4-5份七甲基三硅氧烷和0.01-0.02份催化剂;取腰果酚、环氧氯丙烷、苄基三乙基氯化铵,氮气氛围下,升温搅拌反应,降温,加入氢氧化钠,水洗至中性,减压蒸馏,得到甘油醚;将甘油醚和二乙醇胺,搅拌加热反应,水洗,有机相减压蒸馏除去水分,得到多元醇;将多元醇、七甲基三硅氧烷和催化剂搅拌混合,升温反应,降温,加入活性炭,继续反应,过滤,保留滤液,减压蒸馏滤液,得到酚胺基多元醇。
通过采用上述技术方案,本申请技术方案优选采用腰果酚制备酚胺基多元醇,由于腰果酚胺基多元醇与异氰酸酯反应时,分子结构中的叔胺基团能够与异氰酸酯形成络合物,络合物能够使异氰酸酯氮原子上孤对电子的电子云密度变大,形成氧负离子,氧负离子能够与多元醇生成氨基甲酸酯,进而高效促进瑜伽垫中的组分进行自交联。通过调控酚胺基多元醇在A料中的含量,能够有效提高瑜伽垫中的交联密度,改善瑜伽垫的抗撕裂效果。
其次,本申请技术方案采用含硅化合物对酚胺基多元醇进行改性处理,对酚胺基多元醇上的不饱和侧链进行硅烷化改性,硅烷化改性后,改善了酚胺基多元醇的粘度,适宜的粘度能够增加发泡材料与抗撕裂垫之间的结合效果,因此在外力作用下,抗撕裂层能够稳定起到抗撕裂效果。并且硅烷化改性后,有机硅的加入能够促进发泡材料的发泡效果,增大泡沫的交联密度,进一步提高了瑜伽垫的抗撕裂效果。
优选的,所述酚胺基多元醇的黏度为2000mPa·s -3000mPa·s。
通过采用上述技术方案,本申请技术方案优化了酚胺基多元醇的粘度,适宜的粘度能够提高发泡材料与抗撕裂层之间的结合效果,改善瑜伽垫的抗撕裂效果;改善瑜伽垫的发泡效果,降低因粘度过高抑制瑜伽垫的发泡效果,因此瑜伽垫能够获得致密的交联泡孔,提高瑜伽垫的弹性。
优选的,所述发泡材料中硬段含量为25-30%。
通过采用上述技术方案,本申请技术方案优化了A料和B料之间的配比,适宜的硬段含量能够提高发泡材料的粘度以及弹性,改善发泡材料与抗撕裂层之间的结合强度,增强瑜伽垫的抗撕裂效果。同时,适宜的硬段含量能够提高发泡材料的储能模量,在升温发泡过程中,机械性能维持稳定,泡孔对大气压的承受能力提高,因此降低发泡材料中泡孔的收缩率,维持发泡材料中的泡孔交联密度,不仅增加发泡材料与抗撕裂层之间的结合效果,还提高了发泡材料的弹性。
优选的,所述A料还包括增塑剂、有机锡催化剂和填料,所述填料包括皮革微粉。
通过采用上述技术方案,本申请技术方案优选在发泡材料中添加皮革微粉,由于皮革微粉中具有较多的胶原蛋白,由于胶原蛋白具有较高的粘结性;并且皮革中具有天然的胶原纤维,胶原纤维能够进一步提高发泡材料与抗撕裂层之间的结合效果,因此发泡材料中能够通过胶原纤维与抗撕裂层之间形成互穿的网络结构,稳定提高瑜伽垫的抗撕裂效果。
此外,超微皮革粉体在发泡材料中能够交叉排列分布,改变泡孔结构,破坏部分封闭的泡孔结构,增加发泡材料中贯通的通孔结构,进一步改善了瑜伽垫的透湿透气性,减少瑜伽垫上汗液等的堆积,降低运动者在瑜伽垫上打滑,提高瑜伽垫的使用体验。
优选的,所述皮革微粉的制备包括以下步骤:取废弃皮革置于粉碎机中,进行粉碎处理,滤网过滤,得到微粉;将微粉与分散剂搅拌混合,剪切分散,得到皮革微粉;所述分散剂包括硅烷偶联剂、海藻酸钠、磺酸盐中的任意一种。
通过采用上述技术方案,本申请技术方案中优选采用硅烷偶联剂对皮革微粉进行改性处理,通过亲水基团对皮革微粉进行包裹,提高了皮革微粉在水中的分散效果,降低皮革微粉的团聚的可能性。
海藻酸钠包裹皮革微粉,通过增加皮革微粉的表面活性基团,通过静电斥力等,阻碍皮革微粉之间形成团聚,改善皮革微粉在发泡材料中的分散均匀性,使皮革获得均匀的抗撕裂效果以及透湿透气效果。
而磺酸盐的加入能够作为亲水扩链剂引入到发泡材料中,因此提高皮革微粉与发泡材料之间的相容性,使皮革微粉能够均匀分散于发泡材料中。
优选的,所述填料还包括木粉、纤维中的任意一种,所述纤维包括经酶解处理的纤维。
通过采用上述技术方案,本申请技术方案在填料中添加木粉和纤维,木粉镍包括木质素以及木质纤维,通过多种软硬不同的纤维进行配合,在发泡材料中形成交错的网络结构,有效提高发泡材料与抗撕裂层之间的结合强度。
在填料中添加经酶解处理的纤维,酶解处理后,使纤维转变为纤维素,纤维素晶能够与发泡材料中多元醇的分子链进行缠结,抵抗分子链间滑移,提高了发泡材料中能够提高发泡材料的粘度,进一步提高了发泡材料与抗撕裂层之间的结合强度。
优选的,所述经酶解处理的纤维包括以下制备步骤:取纤维,将纤维浸渍于甲酸和盐酸的混合溶液中,升温、浸渍处理后,过滤,保留固体物,干燥,得到一次处理纤维;取一次处理纤维和酶解溶液,搅拌混合,酶解处理,离心分离,保留固体物,干燥,研磨,得到经酶解处理的纤维。
通过采用上述技术方案,在酶解处理前,采用甲酸和盐酸的混合溶液对纤维进行预处理,溶解破坏纤维中的半纤维素以及木素组分,保留纤维素组分,提高后续酶解时纤维素的溶出效果,使纤维素能够对发泡材料中的泡孔内壁进行支撑,提高发泡材料的模量;因此在增加了发泡材料与抗撕裂层之间的结合效果的同时,提高了发泡材料的泡孔稳定性,协同提高瑜伽垫的抗撕裂效果。
优选的,所述甲酸和盐酸的混合液中,甲酸的质量浓度为60-80%,盐酸的质量浓度为0.5-1.0%。
通过采用上述技术方案,本申请技术方案优化了甲酸和盐酸的质量浓度,适宜的浓度,能够在适宜的时间内,去除大部分半纤维素以及木质素,保留大部分纤维素,维持纤维素的含量,能够有效通过纤维素提高发泡材料中泡孔的稳定性。
综上所述,本申请具有以下有益效果:
1、由于本申请采用在发泡材料中添加酚胺基多元醇,通过酚胺基多元醇中的叔胺基基团能够与异氰酸酯进行络合,络合物继续与多元醇反应,能够有效催化发泡材料进行自催化交联,在发泡材料中形成交联的网络结构,通过网络互穿,增加发泡材料与抗撕裂层之间的结合效果,因此瑜伽垫获得了较佳的抗撕裂效果。
2、本申请中优选采用在发泡材料中增加皮革微粉,一方面,皮革微粉中具有胶原蛋白,胶原蛋白能够增加发泡材料的粘结性,改善发泡材料与抗撕裂层之间的结合效果;另一方面,皮革微粉中还具有胶原纤维,胶原纤维能够连通部分封闭孔隙,形成连通的孔隙,提高了发泡材料的透湿透气性,提高瑜伽垫的使用体验。

本对比例与实施例3的不同之处在于,瑜伽垫中未添加抗撕裂层。
对比例2
本对比例与实施例3的不同之处在于,本对比例中未添加酚胺基多元醇。
性能检测试验
(1)抗撕裂强度:参照ASTM D624标准进行撕裂强度的测定。
(2)柔韧性:利用RT-10型电子万能试验机测试样品的拉伸性能,通过断裂伸长率来表征运动垫的柔韧性能,测定样品采用测试标准中的哑铃形状,上下两端面相互平行,且与轴线垂直,每个样品做三次试样取平均值,加载速度为500mm/min,测试标准采用GB/T528-2009。
(3)弹性:采用邵尔硬度测量瑜伽垫的硬度,利用邵尔硬度A与回弹率%表示弹性能大小;
(4)表观情况:肉眼观察剥离后的发泡运动垫表面的气泡情况。
表4实施例1-14、对比例1-2性能检测
结合表4性能检测对比可以发现:
(1)结合实施例1-3和对比例1-2对比可以发现:实施例1-3中制得的瑜伽垫的抗撕裂性能以及弹性有所提升,这说明本申请优选了适宜的发泡温度以及去湿温度,适宜的温度使得发泡材料能够均匀稳定且高效进行发泡,通过较量的泡孔结构,不仅提高瑜伽垫的弹性,还能够与抗撕裂层之间高效结合,改善瑜伽垫的抗撕裂效果。
同时,采用TPU对聚四氟乙烯网进行改性处理,能够改善抗撕裂层与发泡材料之间的结合效果,并且能够一同进行发泡,通过交联的泡孔,能够进一步提高抗撕裂层与发泡材料之间的结合效果,提高瑜伽垫的抗撕裂效果。根据表4可以看出,实施例2中制得的瑜伽垫的抗撕裂性能以及弹性较佳,说明此时瑜伽垫的去湿温度以及发泡温度较为合适。
(2)结合实施例4-5、实施例6-7、实施例8-9和实施例2对比可以发现:实施例4-9中制得的瑜伽垫的抗撕裂性能以及弹性有所提升,这说明本申请技术方案优化了发泡材料中硬段的含量,适宜的硬段含量能够使发泡材料获得较佳的粘度,并且优化了酚胺基多元醇的制备,提高了发泡材料的自催化效果,有效改善了发泡材料与抗撕裂层之间的结合强度,提高瑜伽垫的抗撕裂效果。根据表4可以看出,实施例4和实施例7中制得的瑜伽垫的抗撕裂性能以及弹性较佳,说明实施例4中多元醇各组分比例较为合适,实施例7中瑜伽垫中硬段的含量较为适宜。
(3)结合实施例10-14和实施例2对比可以发现:实施例10-14中制得的瑜伽垫的抗撕裂性能以及弹性有所提升,这说明本申请采用木粉、皮革微粉以及改性处理的纤维配合作为填料,通过胶原纤维、胶原蛋白、木质纤维、玉米纤维以及纤维素配合,一方面,形成交联的三维结构,增加对发泡材料的支撑效果,与抗撕裂层之间形成交互的网络结构,提高抗撕裂层与发泡材料之间的结合效果;另一方面,提高了泡孔的稳定性,进一步提高瑜伽垫的弹性,因此瑜伽垫获得长效的抗撕裂效果以及弹性。根据表4可以看出,实施例14中制得的瑜伽垫的抗撕裂性能以及弹性较佳,说明此时的甲酸和盐酸混合溶液的浓度较为适宜。
本具体实施例仅仅是对本申请的解释,其并不是对本申请的限制,本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改,但只要在本申请的权利要求范围内都受到专利法的保护。
