Description
技术领域
本发明属于功能纤维及复合材料技术领域，具体涉及一种多功能纤维复合天然乳胶制品及其制备方法。
背景技术
近年来，随着人民生活水平迅速提高和健康意识的日益增强，具有高舒适度及健康功能的枕头、床垫之类的床上用品行业正迎来蓬勃的发展。乳胶发泡海绵制品采用纯天然乳胶汁提炼制备而成，自然环保无污染，且本身具有一定的防螨抗菌能力；其蜂窝状设计可达到良好的透气效果，快速散发人体产生的热量；其独特的柔软触觉和乳胶高弹性能够顺应身体轮廓，达到健康安稳舒适的睡眠效果，成为近年来最火爆的寝具内充材质，深受广大消费者的喜爱。但乳胶发泡制品普遍存在发泡不均一，制品内部缺陷等问题，导致强度及耐用性不足的缺陷，同时由于乳胶发泡制品的制造工艺比较单一，对乳胶发泡制品附加健康保健功效的研究较少。
专利CN 106832455 A公开了一种能促进睡眠的乳胶发泡海绵。该乳胶发泡海绵，其原料按照质量份包含以下组分：100份天然胶乳、0.5～3.0份硫化剂、0.5～3.0份起泡剂和0.1～5.0份芳香植物精油微胶囊。该发明的乳胶发泡海绵制成的枕头或床垫，由于包含芳香植物精油微胶囊，能够缓释出芳香植物精油成分，从而能够促进舒缓神经、减轻压力、抚慰情绪以促进睡眠。该专利技术对乳胶发泡进行植物精油功能改性，但未对其发泡、强度及耐用性方面进行研究。专利CN110982131A公开了一种利用低蛋白胶乳生产乳胶发泡制品的方法。所述天然乳胶发泡制品的制备原料，以重量份计，包括胶乳100、硫化剂2～5、起泡剂0.5～6、穏泡剂1～5、胶凝剂0.5～1.5、活性剂3～5、助剂3～12、填料1～15。通过在乳胶发泡制品的生产制备过程中加入了适量的穏泡剂、活性剂，同时改变了生产工艺参数，使得制备的乳胶发泡制品具有很好的泡沫稳定性，泡孔尺寸均一，孔眼结构规整稳定，制品内部缺陷少等，制备所的发泡制品回弹性好，拉伸强度、断裂伸长率、回弹率等均得到显著的提升。但其使用的功能助剂较复杂。
具有健康保健功效的功能纤维材料技术已比较成熟，如具有抗菌、抗病毒、防霉、防螨、远红外、负离子、消臭、除醛、阻燃等健康保健功效的多功能纤维已有较多报道。在我们的前期申请中，也取得了较多的研究成果(CN 2020104460599、CN 2021109694785、CN202111480990X)。目前，采用功能纤维复合乳胶材料制备枕头、床垫、坐垫、等制品的商业化产品较少，具备广阔的市场前景。
发明内容
针对以上现有技术存在的缺点和不足之处，本发明的首要目的在于提供一种多功能纤维复合天然乳胶制品的制备方法。

进一步地，步骤(1)中所述混合纺丝的方法可通过先制备功能母粒后共混纺丝或直接共混纺丝；所述纺丝的方法不限于熔融纺丝、溶液纺丝、静电纺丝、干法纺丝、湿法纺丝等。

进一步地，步骤(2)中所述硫化剂由硫黄、活性剂氧化锌和促进剂PX(乙基苯基二硫代氨基甲酸锌)组成。
进一步优选地，所述硫化剂的用量为天然乳胶液质量的0.8％～4％。
进一步地，步骤(2)中所述表面活性剂为阴离子表面活性剂；优选为脂肪酸盐(如月桂酸钠)、脂肪醇硫酸盐(如十二烷基硫酸钠)或烷基苯磺酸盐(如十二烷基苯磺酸钠)阴离子表面活性剂。

与现有技术相比，本发明的有益效果是：
(1)本发明将具有健康保健功能的多功能纤维材料与天然乳胶发泡材料进行结合，制备成枕头、床垫、坐垫等产品，能够结合多功能纤维材料的健康保健功能和天然乳胶材料的舒适功能。

具体实施方式
下面结合实施例对本发明作进一步详细的描述，但本发明的实施方式不限于此。
实施例1
本实施例的一种多功能纤维复合天然乳胶床垫的制备方法，包括如下制备步骤：
(1)多功能纤维材料制备：
将10重量份石墨烯及抗菌氧化锌纳米粒子与89.5重量份聚酯纤维切片在高速混合机中混合均匀，然后加入0.5重量份热稳定剂季戊四醇硬酯酸酯，再将混合物用双螺杆挤出机挤出得到石墨烯抗菌聚酯母粒。将所得石墨烯抗菌聚酯母粒与聚酯纤维切片混合后进行熔融共混纺丝，得到石墨烯抗菌多功能聚酯纤维。
(2)天然乳胶发泡材料制备：
将100重量份天然乳胶液与2重量份硫化剂(由1重量份硫黄、0.4重量份活性剂氧化锌和0.6重量份促进剂PX组成)、1.2重量份阴离子表面活性剂月桂酸钠和不同重量份硅橡胶增强粒子搅拌混合均匀，然后在200r/min转速及氮气保护条件下搅拌起泡20min，得到发泡胶料；将发泡胶料注入到模具中，先在60～70℃预硫化1h，然后送入105～110℃蒸汽室中深度硫化2h，冷却定型后切片，得到天然乳胶发泡材料。
(3)复合制品的制备：
以步骤(1)所得多功能纤维材料为面料，步骤(2)所得天然乳胶发泡材料为填充料，复合制备得到多功能纤维复合天然乳胶床垫。
本实施例中所用硅橡胶增强粒子为阳离子改性的硅橡胶增强粒子，其通过如下方法制备得到：
按重量份计，将100份粘度(25℃)为120cst的羟基硅油溶解于异丙醇中，然后加入10份气相二氧化硅搅拌分散均匀，将体系加热至65～75℃，加入6份氨乙基氨丙基三甲氧基硅烷进行交联反应1.5h，然后加入氨乙基氨丙基三甲氧基硅烷摩尔量0.8倍的2,3-环氧丙基三甲基氯化铵进行阳离子化反应3h，反应完成后将产物经真空干燥脱除溶剂，得到阳离子改性的硅橡胶增强粒子。
1)为研究不同硅橡胶增强粒子加入量情况下对天然乳胶发泡材料的影响，分别调整硅橡胶增强粒子的加入量为0重量份、1重量份、2重量份、3重量份、4重量份、5重量份、6重量份。测试所得天然乳胶发泡材料的泡孔均匀性(显微镜观察测试切片在一定范围内的泡孔完整性(以完整泡孔占所有泡孔的百分比)及均匀性(目测泡孔的大小均匀度，以优、良、差三个等级标准))、拉伸强度和断裂伸长率(GB/T 528-1998)，测试结果如下表1所示。
表1
| 增强粒子加入量 | 泡孔完整性 | 泡孔均匀性 | 拉伸强度 | 断裂伸长率 |
| 0 | 62％ | 差 | 0.14MPa | 156％ |
| 1％ | 78％ | 良 | 0.19MPa | 185％ |
| 2％ | 92％ | 优 | 0.25MPa | 232％ |
| 3％ | 94％ | 优 | 0.28MPa | 249％ |
| 4％ | 97％ | 优 | 0.31MPa | 278％ |
| 5％ | 98％ | 优 | 0.32MPa | 267％ |
| 6％ | 98％ | 优 | 0.31MPa | 262％ |
由表1结果可知，通过在天然乳胶发泡材料中引入硅橡胶增强粒子，可显著增强天然乳胶发泡材料的力学强度。且可以看出，本发明加入阳离子改性的硅橡胶增强粒子对乳胶的发泡性能影响显著，相比不加入阳离子改性的硅橡胶增强粒子的情况下，本发明天然乳胶发泡材料的泡孔完整性及泡孔均匀性均明显改善，在硅橡胶增强粒子的加入量为天然乳胶液质量的2％～6％情况下，所得天然乳胶发泡材料的各项性能均达到较优水平。说明本发明的阳离子改性的硅橡胶增强粒子与阴离子表面活性剂协同作用，通过相反离子的缔合作用和疏水部分的相互作用，能够提高表面活性，达到良好的起泡性及稳泡性，从而显著提高产品质量。
2)为研究不同交联剂加入量对所得硅橡胶增强粒子的影响，分别调整氨乙基氨丙基三甲氧基硅烷的加入量为1重量份、3重量份、5重量份、8重量份、10重量份、12重量份。测试所得硅橡胶增强粒子的形态及粒径，并测试在4％加入量条件下对天然乳胶发泡材料增强效果的影响，结果如下表2所示。
表2
| 交联剂加入量 | 1％ | 3％ | 5％ | 8％ | 10％ | 12％ |
| 形态及粒径 | 黏连结团 | 100～900nm | 100～500nm | 40～200nm | 10～100nm | 10～100nm |
| 拉伸强度 | ---- | 0.26MPa | 0.28MPa | 0.32MPa | 0.32MPa | 0.32MPa |
| 断裂伸长率 | ---- | 219％ | 236％ | 281％ | 295％ | 308％ |
由表2结果可见，交联剂加入量过低会导致交联程度不够，硅橡胶增强粒子之间产生黏连结团，分散性能降低，随着交联剂加入量的增加，所得硅橡胶增强粒子的粒径呈现降低的趋势，其在天然乳胶液中的分散性能更优，从而达到更好的增强力学性能的效果。
3)为研究不同阳离子化程度对所得硅橡胶增强粒子及天然乳胶发泡材料性能的影响，分别调整2,3-环氧丙基三甲基氯化铵的加入量为氨乙基氨丙基三甲氧基硅烷摩尔量的0倍、0.3倍、0.5倍、0.6倍、0.7倍、0.9倍、1.0倍，测试所得硅橡胶增强粒子的粒径，并测试在4％加入量条件下对天然乳胶发泡材料增强效果的影响，结果如下表3所示。
表3
由表3结果可知，阳离子化程度对所得硅橡胶增强粒子的粒径影响显著，其原因可能在于阳离子化程度越高，硅橡胶增强粒子在制备成核过程中的静电斥力越大，粒子间的黏连结团程度降低，从而使得粒径降低；同时其阳离子化程度越高，与阴离子表面活性剂的缔合作用越强，显著促进胶束在硅橡胶增强粒子表面形成，产生更高的表面活性，并最终改善其在天然乳胶液中的分散性能和达到更好的增强力学性能的效果。另外由发泡性能结果可知，发泡均匀性及稳定性的提高主要在于阳离子化，相比未阳离子化的硅橡胶增强粒子，本发明所得天然乳胶发泡材料的发泡均匀性及稳定性显著改善，且随着阳离子化程度的提高，这种改善效果越显著，说明本发明阳离子改性的硅橡胶增强粒子在阴离子表面活性剂作为发泡剂的情况下，通过相反离子的缔合作用和疏水部分的相互作用，能够提高表面活性，具有显著提高发泡均匀性及稳定性的技术效果。
