Description

一种PVC无甲酰胺发泡剂
技术领域
本发明涉及一种发泡剂，特别涉及一种PVC无甲酰胺发泡剂，属于PVC制品技术 领域。
背景技术
聚氯乙烯(以下简称PVC)为世界五大通用塑料之一、具有价格低廉、难燃、耐 腐蚀、耐候性好、抗水、热塑性好、电绝缘性能好、机械性能出色等特点，广泛应用于 工业、农业、建材、电力、包装、日化等领域。近年来提倡的以塑代木的环保理念，材 料轻量化的和降低成本的诉求给PVC发泡制品带来了前所未有的新机遇。
然而PVC发泡过程中使用的偶氮二甲酰胺(简称发泡剂ADC)分解产生甲酰胺(又名“氨基甲醛”)残留，被欧盟REACH法规列为高度关注物质(SVHC)，欧盟化学品管 理局分类为具有生殖毒性的物质，一时间各种用发泡剂ADC生产的发泡制品特别是儿 童用瑜伽垫更是为万千准新父母所忌讳。欧盟规定的泡沫制品中甲酰胺的含量不可超过 200ppm的规定一时间将出口的PVC发泡制品推向风口浪尖，使甲酰胺事件由环保变成 了贸易壁垒，在行业内一度引起不小的轰动，各厂家纷纷商榷应对之策，面对环保和成 本的双重压力，找寻无甲酰胺残留的ADC替代品迫在眉睫。PVC行业很多制品厂曾尝 试单独使用碳酸氢钠作为发泡剂，但是发泡剂用量大，发泡效果不佳，无法生产高发泡 倍率的PVC泡沫制品。
发明内容
本发明的目的在于一种PVC无甲酰胺发泡剂，该PVC无甲酰胺发泡剂代替目前 PVC常用的发泡剂ADC，实现了PVC制品无甲酰胺残留。
本发明解决其技术问题所采用的技术方案是：
一种PVC无甲酰胺发泡剂，该PVC无甲酰胺发泡剂是由如下以重量份计的组分混合得到：发泡剂30-95份、甲酰胺去除剂5-20份、成核剂0-50份、环氧大豆油2-5份、 改性剂0-50份。本发明各原料组分按比例加入混料机内混合均匀即可，对于有无尘要 求的适当增加改性剂的用量并于密炼机中混炼均匀(混炼至90℃左右即可出料)后投 入挤出机造粒得到成品。
作为优选，该PVC无甲酰胺发泡剂是由如下以重量份计的组分混合得到：发泡剂50-90份、甲酰胺去除剂5-10份、成核剂0-10份、环氧大豆油2-5份、改性剂0-50份。
作为优选，发泡剂为偶氮二甲酰胺(发泡剂ADC)、碳酸氢钠、4,4'-氧代双苯磺酰肼(发泡剂OBSH)、对甲苯磺酰胺基脲(发泡剂RA)、N,N'-二亚硝基五次甲基四胺(发 泡剂DPT)、尿素(发泡剂BK)、对甲苯磺酸肼(发泡剂TSH)中一种或多种之混合物。
作为优选，甲酰胺去除剂为三乙醇胺、氧化钙、氢氧化钙、焦磷酸钠、焦磷酸钾或碳酸氢钠中的一种或几种之混合物。
作为优选，成核剂为碳酸钙、滑石粉、蒙脱土、硅灰石、膨润土、柠檬酸一钠、柠 檬酸、磷酸二氢钠、硫酸铝钾、柠檬酸钙、柠檬酸镁、柠檬酸铝或甲基丙烯酸锌中的一 种或几种之混合物。
作为优选，改性剂是用于颗粒发泡剂的载体，选自甲基丙烯酸甲酯—丁二烯—苯乙 烯共聚物(抗冲击改性剂MBS)、抗冲击改性剂ACR、抗冲改性剂ACM树脂、AMB 抗冲改性剂中的一种或几种之混合物。
作为优选，该PVC无甲酰胺发泡剂是由如下以重量份计的组分混合得到：偶氮二甲酰胺25-30份、碳酸氢钠15-25份、发泡剂OBSH 0-5份、发泡剂RA 0-5份、三 乙醇胺0-2份、氢氧化钙5-8份、焦磷酸钠2-3份、柠檬酸一钠5-10份、甲基丙烯 酸锌2-5份、丙烯酸酯共聚物ACR401 28-30份。
本发明的有益效果是：
(1)本发明利用甲酰胺在强碱性催化剂的作用下于高温环境(加工温度)水解的反应，巧妙地在挤出生产加工阶段消除了偶氮二甲酰胺分解产生的甲酰胺，对原生产工艺 和基础配方无影响，可用于不同发泡倍率的PVC的生产加工；
(2)本发明向体系中引入成核剂，可有效降低泡孔尺寸，赋予发泡制品更加细腻的泡孔结构；
(3)在体系内引入环氧大豆油，在改善发泡剂的分散性，降低了发泡剂的吸水性，提高了产品的存储稳定性，同时改善了发泡制品的外观；
(4)将丙烯酸类改性剂引入体系，在降低粉尘污染的同时，减少了常规聚合物例如聚乙烯等对材料性能的影响，有效调节发泡泡孔结构，使发泡制品的内部结构更加细腻，外观更加光滑规整；
(5)首次使用抗冲改性剂作为载体进行PVC用发泡剂的颗粒化。
具体实施方式
下面通过具体实施例，对本发明的技术方案作进一步的具体说明。应当理解，本发明的实施并不局限于下面的实施例，对本发明所做的任何形式上的变通和/或改变都将 落入本发明保护范围。
在本发明中，若非特指，所有的份、百分比均为重量单位，所采用的设备和原料等均可从市场购得或是本领域常用的。下述实施例中的方法，如无特别说明，均为本领域 的常规方法。
