Description

一种聚氨酯海绵及其加工方法
技术领域
本发明属于高分子材料技术领域，具体涉及一种聚氨酯海绵及其加工方法。
背景技术
聚氨酯中文全名为聚氨基甲酸酯简称聚氨酯,根据产品的物理性能可以分成聚氨酯硬泡、聚氨酯软泡、PU自结皮海绵等，生产中修改配方，便可获得不同的密度、弹性、刚性等物理性能。其中的聚氨酯软泡也就是我们常常叫做聚氨酯海绵的材料，按软硬程度即耐负荷性能的不同，聚氨酯海绵泡可以分为普通软泡、超柔软泡、高承载软泡、高回弹软泡等。相对于天然乳胶产品昂贵的价格，聚氨酯海绵因其价格低廉，且可以通过工艺和配方的改进，生产出慢回弹、高回弹、高弹等不同功能的产品，广泛用于沙发、枕芯、床垫等产品内部以及家居装修中，很好地兼顾了性价比、舒适性和功能性。
聚氨酯海绵用于上述家居产品，因为无法用水洗清洁，时间久了难免会滋生细菌发生霉变等问题，不利于人体健康。此外，作为生产生活中广泛使用的有机材料，聚氨酯海绵属于易燃物，燃烧中还产生有毒有害气体，因此对其有防火阻燃的性能要求。此外，人们还希望赋予聚氨酯海绵具有释放负离子对人体友好等功效。在这样的背景下，我司对于功能性聚氨酯海绵也展开了不断的研究，期望给予产品更好的功能，提高产品的市场竞争力。
发明内容
本发明提供了一种聚氨酯海绵及其加工方法，生产的聚氨酯海绵具有防火阻燃、抗菌抗霉变、持续释放负离子等功能。
为了实现上述发明目的，本发明采用的技术方案如下：
一种聚氨酯海绵，其特征在于，由A组分和B组分经混合搅拌发泡反应生成；A组分包括阻燃型聚醚多元醇、聚合物多元醇、催化剂、硅油、水；B组分包括二异氰酸酯、抗菌剂。
具体地，按照重量份计，A组分包括阻燃型聚醚多元醇40～60份、聚合物多元醇40～60份、催化剂0.5～1份、硅油1～3份、所述水为去离子水2～4份；B组分包括二异氰酸酯40～60份、抗菌剂0.5～2份。
具体地，所述阻燃型聚醚多元醇为使用含卤素的环氧化合物单体和含磷、锑等化合物与起始剂混合物进行开环聚合，生成的复合型聚醚多元醇；聚醚多元醇的摩尔质量为3000～5000g/mol。
具体地，所述甲苯二异氰酸酯由2，4-TDI和2，6-TDI两种异构体组成；按重量份计，2，4-TDI占80％，2，6-TDI占20％。
具体地，所述抗菌剂为二氧化钛光触媒系抗菌剂、二氧化钛载银无机抗菌剂、季铵盐抗菌剂、季鏻盐抗菌剂中的任意一种或者多种组合使用。
具体地，所述催化剂选自辛酸亚锡、二丁基锡、三乙醇胺、三乙烯二胺、三乙胺中的一种或多种组合使用。
具体地，所述A组分还包括辅助发泡剂二氯甲烷。
具体地，所述A组分还包含电气石粉末，所述电气石粉末颗粒直径为100～1000nm，总含量不超过1份。
具体地，所述B组分还包含总重量不超过1份的阻燃剂乙基磷酸二乙酯、总含量不超过0.5份防霉剂8-羟基喹啉铜。
本发明还公开了一种聚氨酯海绵的加工方法，根据前述配方的原材料以及配比，包括如下步骤：
1)将A组份原料加入搅拌器中2000-5000r/min下搅拌5～25min,待用；
2)将B组原料加入搅拌器中与A组原料混合，在3000-5000r/min下搅拌30-60s，倒入发泡容器内发泡；
3)自然熟化2-4小时；
4)脱模，获得成品；
5)根据使用需要切割成所需形状。
本发明的有益效果在于：1、在A料中直接添加具有阻燃功能的型聚醚多元醇，选择性在B料中添加乙基磷酸二乙酯阻燃剂，不含卤素黏度低，在AB料双组分体系中十分稳定，工艺简单的同时赋予产品良好的防火阻燃性能；2、B料中加入的抗菌剂和防霉剂给予产品良好的防霉抗菌效果；3、纳米级无机材料电气石粉末的加入，使得产品具有持续散发负离子的功能。本发明在各项性能指标达到预期要求的前提下，生产工艺和配方较为简单，生产过程无需专门进行加热或者制冷等工艺，自然状态发泡和熟化即可进行生产，试样后检测生产成功率非常高，生产的聚氨酯海绵具有明显的防火阻燃、抗菌抗霉变、持续释放负离子等功能，有利于提高产品的竞争力。

实施例4
1)准确量取准备A、B组份原料，按重量份计，A组分包括：阻燃型聚醚多元醇40份、聚合物多元醇40份、二丁基锡和三乙胺按照1：1配比的催化剂0.8份、硅油3份、去离子水2份、二氯甲烷2份；B组分包括市售TDI80/20 60份、二氧化钛光触媒系抗菌剂抗菌剂2份、防霉剂8-羟基喹啉铜0.3份、直径为100～1000nm电气石粉末0.5份；2)将A组分加入搅拌器中3000r/min下搅拌15min,检查各项指标合格待用；
3)将B组原料加入搅拌器中与A组原料混合，在4000r/min下搅拌45s，倒入发泡容器内发泡；
4)自然熟化2-4小时；
5)脱模，获得成品；
6)根据使用需要切割成所需形状。
实施例4中使用的发泡剂二氯甲烷是一种活性更高的发泡剂，适于生产弹性更高更蓬松的海绵制品，使用量控制在1-3份之间，对于大部分慢回弹海绵制品来说无需添加。
对上述实施例制备的聚氨酯海绵进行简单检测，结果如下：1、均具有阻燃功能，遇明火时不会燃烧，仅呈现局部碳化，能有效地抑制火焰的蔓延；2、使用手持式负离子检测仪对生产的海绵成品进行检测均能检测到负离子存在，且添加了电气石粉末的海绵周边负离子浓度明显大于未添加的配方产品，随着添加量增加呈一定上升趋势；3、将本发明提供的具有抗菌功能的海绵样品送检，对大肠杆菌、金色葡萄糖菌的抑制作用菌达到80％以上；4、未进行标准防霉试验，将海绵样品置于阴暗潮湿处数天，添加了防霉剂的样品霉变程度明显低于未添加防霉剂和抗菌剂的产品。上述配方生产的海绵在理化性能测试按照本司检测标准进行，因配方不同略有差异，均在预期范围之内。可以得出结论，本发明提供的技术方案完全能够满足聚氨酯海绵的某些特殊功能要求，尤其有利于人体健康。
以上所述实施例仅仅是为了说明本发明的一些较佳例子，众所周知在聚氨酯海绵生产领域，对于实际的原材料添加量、反应时间和发泡方式等的选择有一定的随机性，有时候与不同原料来源均有关系。因此，上述实施例并不能用来限制本发明的保护范围，本发明的保护范围以权利要求书所述内容为准，任何简单的配方替换和工艺改变均落入本申请的保护范围之内。
