Description

一种PE发泡材料瑜伽垫及其制备方法
技术领域
本发明涉及PE材料的技术领域，尤其是涉及一种PE发泡材料瑜伽垫及其制备方法。
背景技术
聚乙烯具有优良的物理化学性能，同时其具有产量大、价格低廉、容易获得等优点，被广泛应用于各种领域。聚乙烯也是是最早工业化应用的发泡材料之一。发泡材料是指能在物质内部气化产生气泡，使之成为多孔物质的发泡的物质。瑜伽垫主要就是利用发泡材料进行制备得到。
现有的PE发泡材料的制备工艺如公布号CN107057166A的中国发明专利中公开了一种无味PE发泡材料及其制造方法，该无味PE发泡材料主要由以下重量份数的原料制造：50～100份LDPE、10～40份填充剂、1～10份的改性发泡剂、0.1～5份助发泡剂、0.1～10份润滑剂和0.5～1份无味交联剂。该无味PE发泡材料的制备方法包括混料、开炼、出片、硫化发泡和冷却成型加工的步骤。该发明在PE发泡材料中添加改性发泡剂，产品氨气含量小于30ppm，与传统的PE发泡材料相比，无味且环保无毒。
上述中的现有技术方案存在以下缺陷：现有工艺通常是通过化学发泡剂分解产生气体，从而在聚乙烯内生成气泡孔，但是，由于聚乙烯是典型的高结晶度聚合物，在熔点以下具有很高的粘弹性，接近熔点时黏度又急剧降低，化学发泡剂的分解气体在聚乙烯树脂中极易出现泡孔塌陷、关闭或者气体逸出等现象而造成发泡失败，使得聚乙烯发泡材料的成品质量下降。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种PE发泡材料瑜伽垫及其制备方法，通过添加交联剂和助交联剂使得树脂基体产生交联，形成三维网状的结构，提高结构强度，减少泡孔塌陷，提高瑜伽垫的生产质量。
本发明的上述目的是通过以下技术方案得以实现的：
一种PE发泡材料瑜伽垫，其主要由包括以下重量份数的原料制备得到：
Figure BDA0002279964100000011
Figure BDA0002279964100000021
通过采用上述技术方案，低密度聚乙烯树脂作为瑜伽垫原料中的基体树脂，化学发泡剂在助发泡剂的辅助下，通过分解在基体树脂内产生气体，使得基体树脂内部出现有气体挤压产生的气泡孔，而在添加入化学发泡剂的同时，原料中还添加有交联剂，使得聚乙烯分子之间形成三维交联网状的结构，同时由于采用低密度聚乙烯树脂作为基体，聚乙烯分子之间更容易被交联剂交联，更容易形成三维交联网状结构。聚乙烯分子间形成的交联网状结构使得聚乙烯分子的结构强度增强，化学发泡剂产生的气泡不会轻易透过，提高气泡在基体树脂中残留率，从而减少泡孔塌陷、关闭或者气体逸出等现象产生，进入提高聚乙烯树脂的发泡质量，提高瑜伽垫的生产质量。
本发明进一步设置为：所述化学发泡剂选自有偶氮二甲酰胺、N，N－二亚硝基五次甲基四胺和4，4－氧代双苯磺酰肼中的一种或多种。
通过采用上述技术方案，偶氮二甲酰胺、N，N－二亚硝基五次甲基四胺和4，4－氧代双苯磺酰肼都是化学发泡剂，可以在加压加热的条件下发生分解，产生氮气、二氧化碳等气体对基体树脂进行发泡。
本发明进一步设置为：所述交联剂包括以下重量百分比的组分：
过氧化苯甲酰 30～50％；
过氧化二异丙苯 40～60％；
聚乙烯醇 10～20％。
通过采用上述技术方案，过氧化苯甲酰和过氧化二异丙苯作为交联剂的主体，在受热分解时生成初级自由基，初级自由基进攻聚乙烯大分子链，使聚乙烯大分子链上生成不饱和的双键结构(即聚乙烯大分子链自由基)，由于大分子链自由基反应活性较强，当分子链自由基彼此相遇时，便会发生交联反应生成化学键，最终实现交联。聚乙烯醇作为乳化稳定剂，对于过氧化苯甲酰和过氧化二异丙苯在与聚乙烯树脂基体混合时，起到较好的分散效果，使得过氧化苯甲酰和过氧化二异丙苯分散更加均匀，使得聚乙烯树脂的交联效果得到提高。
本发明进一步设置为：所述原料中还添加有0.1～0.3重量份的助交联剂，所述助交联剂选自团丙烯酸酯、三羟甲基丙烷三甲基丙烯酸酯、N，N－间苯基双马来酰亚胺和三烯丙基异氰脲酸酯中的一种或多种。
通过采用上述技术方案，添加助交联剂一方面使得助交联剂与聚合物上的自由基作用，成为聚合物的支链，还可与聚合物自由基反应，提供额外的交联活性点；另一方面，在自由基存在下，助交联剂聚合成多支链的塑料增强填料，从而使得在交联过程中起到调整交联结构、改善胶料性能、提高交联效率和减少副反应的作用。
本发明进一步设置为：所述填充剂包括以下重量百分比的组分：
Figure BDA0002279964100000031
通过采用上述技术方案，碳酸钙作为填充剂添加入树脂基体中时，可以提高瑜伽垫的耐酸腐蚀性能，在遇到酸时会分解产生二氧化碳，从而起到一定的耐腐蚀性能。滑石粉和高岭土可以改善树脂的发泡过程中气泡产生的均匀性，以及稳定性，滑石粉和高岭土具有化学惰性、高的覆盖能力、理想的流动性能，且成本较低，对于提高解题的耐久性以及机械性能具有较好的效果。氧化石墨烯结构跨越了一般化学和材料科学的典型尺度，具有两性分子的特性，可以像界面活性剂一样提高碳酸钙、滑石粉和高岭土与树脂基体之间的亲和性能。
本发明进一步设置为：所述填充剂中还添加有空心玻璃微珠和羟乙基壳聚糖,所述填充剂包括以下重量百分比的组分：
Figure BDA0002279964100000032
通过采用上述技术方案，填充剂中额外添加的空心玻璃微珠可以提高树脂基体的机械强度，同时在瑜伽垫的制作过程中，在压膜发泡时，部分空心玻璃微珠会发生破裂，从而释放空心玻璃微珠中的气体，起到辅助提供气体产生气泡的作用，使得在化学发泡剂产生气泡的同时，进一步提高气泡产生的致密程度，提高气泡产生的均匀性。羟乙基壳聚糖主要起到表面活性剂的作用，对于填充剂与树脂基体之间的界面张力起到调节的作用，使得填充剂与树脂基体的混合更加均匀和充分。
同时羟乙基壳聚糖在交联剂的作用下会部分与聚乙烯醇发生交联作用，从而形成类水凝胶，水凝胶具备一定的自修复能力，可以在一定程度上提高瑜伽垫的系修复性能。而且水凝胶具有较好的吸水能力，可以提高瑜伽垫的吸汗性能。
本发明进一步设置为：所述润滑剂选自PE蜡、硬脂酸和硬脂酸锌中的一种或多种。
一种PE发泡材料瑜伽垫的制备方法：包括以下工艺步骤：
S1：将原料按比例加入密炼机中进行混炼，得到混炼料；
S2：将混炼料加入开炼机中进行开炼，得到开炼料；
S3：将开炼料加入出片机中进行压片，得到料片；
S4：将料片送入平板硫化机中进行发泡，得到发泡料；
S5：将发泡料切割加工后得到成品瑜伽垫。
通过采用上述技术方案，通过两步法对原料进行混炼发泡，首先步骤S1中将原料通过密炼机进行混炼，得到混合均匀的混炼料，然后步骤S2再通过开炼使得原料进一步混合均匀，再通过平板硫化机进行发泡，从而得到成品发泡瑜伽垫。
与现有技术相比，本发明的有益效果是：
1、通过在原料中添加交联剂和助交联剂使得树脂基体之间形成稳定的三维网状结构，从而减少发泡过程中对于气泡的透过率以及气泡的塌陷，提高瑜伽垫的生产质量；
2、通过在填充剂中添加空心玻璃微珠和羟乙基壳聚糖，使得填充料在提高树脂基体的机械强度以及耐久性的同时，提高发泡过程中气泡的均匀度。

检测方法
1、密度测试
将成品瑜伽垫裁取20cm×20cm大小面积的发泡材料进行称重，由于采用相同的平板硫化机进行发泡，得到瑜伽垫的厚度基本一致，均为4mm。测得的样品重量数据如下表。
实施例 重量(g) 密度(g/cm<sup>3</sup>)
实施例1 0.0144 0.9
对比例1 0.046 2.85
对比例2 0.027 1.69
对比例3 0.022 1.37
对比例4 0.015 0.93
对比例5 0.023 1.43
结论：通过上表的数据可以得知，实施例1中得到的瑜伽垫的密度比对比例1和2都要大，说明添加有交联剂和助交联剂对于发泡的性能影响较大。而通过实施例1与对比例3～5对比可知，空心玻璃微珠的加入在一定程度上可以提高发泡效果，羟乙基壳聚糖影响较弱。
2、吸水率测试
采用GB/T8810-88《硬质泡沫塑料吸水率试验方法》对实施1以及对比例1～5的成品瑜伽垫进行测试。测试结果如下表。

Figure BDA0002279964100000091
结论：通过上述数据测试结果可知，实施例1与对比例1和2对比可知，实施例1中的瑜伽垫的吸水率远高于对比例1和2，说明瑜伽垫原料中在加入交联剂和助交联剂后，瑜伽垫的发泡效果得到增强，从而使得吸水率得到提高。再通过实施例1与对比例3～5对比可以看出，羟乙基壳聚糖的加入对于瑜伽垫的吸水率具有较大的影响，说明羟乙基壳聚糖加入后形成了部分水凝胶，从而提高了瑜伽垫的吸水率。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
