Description
技术领域
本发明涉及鞋料技术领域,具体涉及一种艾草粉鞋料及其制备方法。
背景技术
近年来制鞋行业的飞速发展也推动着鞋底材料的不断推陈出新,发泡鞋底已逐步取代PVC和橡胶实新等鞋底材料,现阶段主要的发泡鞋底有PE类、EVA类、SBS类和PU类,其中,PE类发泡鞋底有较好的耐磨性、隔热性,但防滑性较弱且易变形;EVA类发泡鞋底的弹性好、防震、耐候性强但机械强度低;SBS类发泡鞋底需要与其他的高聚物配合进行改性,如其制成的TPR鞋底材料具有防滑、透气的特点,但价格相对较高;PU类发泡鞋底的密度小、强度高且弹性好,可根据具体需要进行针对性调整,处理后能展现出阻燃、防静电、抗水解和疏水疏油等特性,能够满足各类鞋子的不同需求,是一种较为理想的鞋底材料。但鞋子在长时间的穿着过程中,一来容易磨损变形,二来在潮湿的环境中容易滋生细菌、产生异味,脚部容易长湿疹、足藓等。
艾草作为我国传统药用植物之一被广泛应用在各种医药和保健产品中。艾草在外用时具有祛湿止痒、抑制病菌、抗炎的效果,可用于治疗皮肤瘙痒、皮肤癣和湿疹等。本发明将艾草粉应用于鞋底材料制备成具有抑制真菌病菌、祛除异味且抗炎止痒的保健功能型鞋料,使其成为一种兼具保健功能性和实用性的鞋底材料,本发明的方案为新型功能性鞋料的开发提供了一定的参考价值。
发明内容
本发明的目的是为了解决上述现有技术的不足而提供一种艾草粉鞋料,所述艾草粉鞋料的质地轻、柔韧抗拉伸、回弹减震性能好、不易吸水且具有抑菌除臭功效,同时为可降解材料,使用后不会对环境造成污染。
本发明的另一目的在于提供一种艾草粉鞋料及其制备方法,该制备方法工艺简单、条件可控、成本低、生产效率高,并且所制得产品的质量稳定。
本发明的目的通过下述技术方案予以实现:
一种艾草粉鞋料,包括以下重量份的原料:
本发明的艾草粉鞋料通过以聚酯预聚体、乙烯-醋酸乙烯共聚物为原料制得的聚酯发泡材料具有良好的力学性能、回弹性和减震性能,硬度适中,并且通过添加艾草粉使得所制鞋料具有较好的抑菌除臭功效。其中,疏水剂的加入使得鞋料的吸水率有所降低;复合发泡剂具有较好的微孔发泡效果,泡孔分布均匀且致密,使得鞋料的密度较低,弹性好且透气性佳;抗氧剂的复合使用使得鞋料具有较好的耐氧化性能和光稳定性,且能够避免鞋料制备过程中的热氧化降解;所述炭黑在本发明中起到补强剂的作用,提高了鞋料的耐磨性、抗紫外线和耐热稳定性,同时也作为颜料,使所制鞋料成色好。
优选的,所述聚酯预聚体A的制备包括如下步骤:称取摩尔比为1.0-1.2:1的1,4-丁二醇和丁二酸混合均匀,在常压氮气保护条件下,升高温度至160-180℃搅拌反应1-2h后,加入催化剂A和抗氧剂A,继续升高温度至200-220℃至几乎无水分馏出,然后逐步减压至5kPa以下进行缩聚反应3-6h后停止反应,即制得所述聚酯预聚体A。
优选的,所述聚酯预聚体B的制备包括如下步骤:称取醇酸摩尔比为1.0-1.3:1的短链二元醇和脂肪族饱和二元酸混合均匀,在常压氮气保护条件下,升高温度至160-180℃搅拌反应1-2h后,加入催化剂B和抗氧剂B,继续升高温度至200-220℃至几乎无水分馏出,然后逐步减压至5kPa以下进行缩聚反应3-7h后停止反应,即制得所述聚酯预聚体B。
优选的,所述短链二元醇为乙二醇、1,3-丙二醇、1,4-丁二醇和1,6-己二醇中的至少两种,所述脂肪族饱和二元酸为丁二酸、戊二酸、己二酸、庚二酸和葵二酸中的至少两种。
优选的,所述催化剂A和催化剂B为对甲苯磺酸、硬脂酸钕、十二烷基苯磺酸钕或钛酸四异丙酯中的至少一种。
优选的,所述抗氧剂A和抗氧剂B均为均为抗氧剂168与抗氧剂1010中的至少一种。进一步优选的,所述抗氧剂A和抗氧剂B均为质量比为1:0.8-1.2的抗氧剂168与抗氧剂1010的组合物。
优选的,所述聚酯预聚体A的数均分子量为6000-10000g/mol,所述聚酯预聚体B的数均分子量为7500-13000g/mol。
本发明采用熔融缩聚法以1,4-丁二醇和丁二酸为原料制得的聚酯预聚体A分子链规整,结晶能力较强,具有较好的强度;以短链二元醇和脂肪族饱和二元酸为原料制得的聚酯预聚体B为无定形的羟基封端的脂肪族饱和共聚酯,具有较高的柔顺性。在上述预聚体的制备过程中,反应温度的控制尤为重要,反应温度过低时,反应单体的活性小,分子量增长慢,而反应温度过高时容易加剧副反应的产生。因此,在上述预聚体的制备中的两段升温均为阶梯式升温方式,能更好地控制反应进程。本发明选用的催化剂A和催化剂B价格低廉、毒性低、不会产生重金属污染,且不具有氧化性,其催化效果好,并且采用上述抗氧剂168和抗氧剂1010的复配使用产生协同效应,可长时间有效防止聚酯氧化。再者,上述聚酯预聚体A和聚酯预聚体B的分子量与所制聚酯弹性体的分子量和力学性能有关,聚酯预聚体A的分子量越大时,所制得聚酯弹性体的硬度提高;而聚酯预聚体B的分子量增大时,其扩链效率高,所制得聚酯弹性体的拉伸强度和断裂伸长率提高,同时也具有较好的回弹性以及耐热稳定性,故而本发明对预聚体的分子量做出上述限定,以得到一种柔韧舒适度高且减震回弹性能好的艾草粉鞋料。
优选的,所述扩链剂为二苯基甲烷二异氰酸酯、对苯二异氰酸酯、萘二异氰酸酯中的至少一种。
本发明采用的扩链剂为二异氰酸酯类扩链剂,其具有较高的反应活性,扩链剂中的-NCO基团与预聚体中的-OH基团反应生成较大分子量的聚酯弹性体,为使扩链反应完全,在本发明中,-NCO基团与-OH基团的摩尔比优选为1.1-1.2。
优选的,所述复合发泡剂为碳酸氢钠、对甲苯磺酰肼、偶氮二异丁腈和偶氮二甲酸二异丙酯中的至少一种或至少两种。作为本发明更优选的方案,所述复合发泡剂为对甲苯磺酰肼与偶氮二甲酸二异丙酯按质量比为1:0.4-0.6混合的组合物。
优选的,所述疏水剂为八氟戊醇,所述交联剂为过氧化二异丙苯或三羟甲基丙烷,所述抗氧剂为抗氧剂BHT、抗氧剂1010和UV531按质量比为1:1:0.4混合的组合物。
本发明采用上述复合发泡剂具有较好的微孔发泡效果,泡孔分布均匀且致密,使得鞋料的密度较低,弹性好且透气性佳。通过上述抗氧剂的复合使用使得鞋料具有较好的耐氧化性能和光稳定性,且能够避免鞋料制备过程中的热氧化降解。另外,为了改善材料的吸水性,本发明选用八氟戊醇作为疏水剂,八氟戊醇具有较低的表面自由能,并且向材料表面迁移的特性,能够有效提高本发明鞋料的疏水性,使鞋料的吸水率有效降低。
本发明的另一目的通过如下技术方案实现:一种如上述艾草粉鞋料的制备方法,包括如下制备步骤:
(1)将干艾叶置于75-85℃烘箱中干燥3-6h,冷却后用粉碎机研磨,再采用过滤装置将艾草粉中的杂质和颗粒过滤后,得到粒径为190-210目的艾草粉,备用;
(2)按上述重量份称取聚酯预聚体A、聚酯预聚体B混合搅拌,在氮气条件下,升高温度至140-150℃将两者搅拌均匀,分三次加入扩链剂混合搅拌后,逐步减压至5kPa以下反应2-6h,即制得所述聚酯弹性体;
(3)按上述重量份称取上述步骤(2)制得的聚酯弹性体、乙烯-醋酸乙烯共聚物、艾草粉、炭黑、交联剂进行机械共混,得到混合物料;
(4)向步骤(3)的混合物料中加入抗氧剂、疏水剂和复合发泡剂进行混炼,混炼温度控制在70-80℃,将混炼后的物料送至造粒机中造粒,得到粒料;
(5)将步骤(4)所得粒料放入用硬脂酸涂刷后的模具中进行模压发泡,即得到所述艾草粉鞋料,其中,发泡温度为160-180℃,发泡时间为5-10min。
本发明的艾草粉鞋料通过上述方法制得,上述制备方法简单可控、生产效率高且清洁环保,生产成本低,所制产品的质量稳定且生产效率高。其中,通过添加艾草粉使得所制鞋料具有较好的抑菌除臭功效,并且以聚酯弹性体与乙烯-醋酸乙烯共聚物为原料制得的鞋料具有柔韧抗拉伸、回弹减震性能佳、疏水性强且耐水解的特点,使用后的废弃物可自然降解,不会对环境造成污染。在上述步骤(2)中,反应温度的控制很重要,温度在大于120°时聚酯预聚体A完全熔融与聚酯预聚体B充分混合分散,并且随着温度的升高,扩链反应效率提高,分子量逐渐变大,但当温度超过150℃时,扩链剂可能发生自聚,因此在步骤(2)中限定温度为140-150℃,并且分次加入扩链剂。
本发明的有益效果在于:本发明通过以聚酯预聚体、乙烯-醋酸乙烯共聚物为原料制得的聚酯发泡材料具有良好的力学性能、回弹性和减震性能,硬度适中,并且通过添加艾草粉使得所制鞋料具有较好的抑菌除臭功效。各原料互相配合,相容性好,其中,疏水剂的加入使得鞋料的吸水率有所降低;复合发泡剂具有较好的微孔发泡效果,泡孔分布均匀且致密,使得鞋料的密度较低,弹性好且透气性佳;抗氧剂的复合使用使得鞋料具有较好的耐氧化性能和光稳定性,且能够避免鞋料制备过程中的热氧化降解;所述炭黑在本发明中起到补强剂的作用,提高了鞋料的耐磨性、抗紫外线和耐热稳定性,同时也作为颜料,使所制鞋料成色好。再者,本发明鞋料的制备工艺简单、条件可控、成本低、生产效率高,且所制产品的质量稳定。

对比例1
本对比例1与实施例2的区别在于:本对比例1不添加乙烯-醋酸乙烯共聚物。
对比例2
本对比例2与实施例3的区别在于:本对比例2采用市售发泡剂AC替代实施例3的复合发泡剂。
对比例3
本对比例3与实施例3的区别在于:本对比例3采用市售TPU树脂BT65AR替代实施例3中步骤(2)制得的聚酯弹性体。
将上述实施例1-4和对比例1-3制得的艾草粉鞋料进行各项物理性能检测,硬度测试按照GB/T531.1-2008标准进行检测;拉伸强度和断裂伸长率测试按照GB/T 531.1-2008标准进行检测;剥离强度测试是将实施例1-4和度比例1-3制得的艾草粉鞋料裁剪成样片,分别采用万能试验机(高铁科技有限公司,AI-7000-MT)进行检测;水解性能测试是将上述所得艾草粉鞋料至于浓度为10%的氢氧化钠溶液中,放置24小时,取出后清洗并烘干,按照剥离强度测试方法测试并记录数据;减震性能采用GB/T30907-2014标准进行测试;所述抗菌性能采用《抗菌防霉塑料防霉等级测试方法》(1999)进行测试。上述实施例1-4和对比例1-3的性能测试结果如下表1所示。
表1实施例1-4和对比例1-3的性能测试数据表
由上述数据表1对比可知,实施例1-4所制得的艾草粉鞋料均表现出较好的力学性能、耐水解性和抗菌能力。与实施例2相比,对比例1所制得的艾草粉鞋料的拉伸强度、断裂伸长率和减震性能出现了明显的降低,剥离强度和水解性能也远不如实施例2,说明乙烯-醋酸乙烯共聚物的加入使材料的弹性、韧性和抗水性显著提升,进而使制得的鞋料具有良好的力学性能、减震缓冲和耐水性能。与实施例3相比,对比例2和对比例3所制得艾草粉的剥离强度、断裂伸长率、水解性能以及减震性能相对下降明显,说明实施例3采用的复合发泡剂具有良好的发泡效果,使得本发明艾草粉鞋料的硬度较低、弹性好且韧性强,再者,本发明分别制备了分子量较小的聚酯预聚体A以及柔韧性好、弹性高的聚酯预聚体B,并将其用于制备聚酯弹性体以及艾草粉鞋料,使所制艾草粉鞋料具有较好的拉伸强度、高弹性减震、耐水性能且剥离强度高,同时具有一定的抗菌除臭功效。
上述的具体实施例是对本发明技术方案和有益效果的进一步说明,并非对实施方式的限定。对本领域技术人员来说,在不脱离本发明构思的前提下任何显而易见的替换均在本发明的保护范围之内。
