一种驱蚊虫聚烯烃发泡材料及其制备方法
技术领域
本发明专利涉及一种聚烯烃发泡材料及其制备工艺，尤其是指一种驱蚊虫聚烯烃发泡材料及其制备方法。
背景技术
聚烯烃类塑料应用范围广泛，具有良好的物理、化学和力学性能，其韧性、挠曲性和缓冲性能良好，并且具有电绝缘、隔热等性质，广泛应用于包装、化工、建筑等领域。聚烯烃类泡沫塑料应用广泛，也是最早成功制得的泡沫塑料之一。早在1941年，美国杜邦公司就利用氮气法成功制备了LDPE泡沫塑料。经过几十年的发展，聚烯烃泡沫塑料已经发展成熟，在品种及应用方面实现了多样化。随着理论研究的不断深入以及发泡技术的进步，泡沫塑料在产量和质量方面都有了长足的进步。
聚烯烃发泡材料以广泛应用于日常生活中，比如竞技类运动垫，休闲瑜伽垫，儿童爬行垫。目前对聚烯烃发泡材料的研究众多，多数集中在发泡材料的回弹性能、保温性能等方面，而对益于身心健康的聚烯烃发泡材料甚少，由于像瑜伽垫、户外运动休闲垫、野外就餐垫等，在户外使用时蚊虫容易爬、飞行到垫子上及周围，从而影响人们正常的休闲运动，因此发明一种靠垫子自身能驱散蚊虫的休闲运动垫用聚烯烃发泡材料具有重要的意义。
发明内容
本发明的目的在于提供一种驱蚊虫聚烯烃发泡材料，其将驱蚊虫中草药粉引入到制备组分中，使用该驱蚊虫聚烯烃泡沫制得的瑜伽垫、运动垫、爬爬垫可以在使用空间内起到较好的驱蚊虫效果，而且中草药的清香及味道不会让人们不适，特别适合于室内休闲健身的运动场所。
本发明的另一目的在于提供这种驱蚊虫聚烯烃发泡材料的制备方法。
为实现上述技术目的，本发明是采用以下技术方案实现的：
一种驱蚊虫聚烯烃发泡材料，其由以下重量份的组分制备而成：
其中，发泡剂母料由AC发泡剂与聚烯烃树脂按1:2混合经密炼、造粒制得，交联剂母料由DCP交联剂与聚烯烃树脂按3.75:75混合经密炼、造粒制得，驱蚊虫母料由驱蚊虫中草药粉与聚烯烃树脂按1:4混合经密炼、造粒制得，上述的比例均为重量比。
所述的聚烯烃树脂为低密度聚乙烯、高密度聚乙烯、聚丙烯中的一种或几种混合物。
所述的AC发泡剂为偶氮二甲酰胺。
所述的DCP交联剂为过氧化二异丙苯。
所述的驱蚊虫中草药粉为含硼为黄花蒿、夜来香、艾叶、天竺葵、食虫草、七里香、薰衣草中的一种或几种的混合物。
所述的加工助剂为硬脂酸锌、抗老化剂、抗静电剂、氧化锌、颜料等中的一种或几种混合物。
一种驱蚊虫聚烯烃发泡材料的制备方法，其包括如下步骤：
1)将AC发泡剂、DCP交联剂、驱蚊虫中草药粉分别与聚烯烃树脂按照比例混合，分次加入密炼机中进行密炼，密炼温度为110—120℃，时间为10min—20min；
2)将密炼后的物料分次经过单螺杆造粒机进行塑化、挤出、造粒，挤出机机身温度设定温度110℃—150℃，螺杆转速为10—20r/min，分别制得发泡剂母料、交联剂母料、驱蚊虫母料；
3)将聚烯烃树脂、发泡剂母料、交联剂母料、驱蚊虫母料、加工助剂、色母料，按比例混合后经单螺杆挤出机挤出片材，螺杆转速20—30r/min，挤出温度120—125℃；
4)挤出的片材经过压延、牵引、冷却进入发泡炉进行发泡，发泡炉温度设定为180—220℃，物料发泡后经冷却、收卷制得驱蚊虫聚烯烃发泡材料。
本发明具有以下有益效果：本发明公开的驱蚊虫聚烯烃发泡材料，其在工艺中加入了驱蚊虫中草药粉，制备的瑜伽垫、运动垫、爬爬垫等终端产品可持久的散发驱蚊气味，有效避免在户外休闲、运动、野外就餐时，蚊虫等对人们休闲的干扰。由于驱蚊虫中草药粉为纯植物成分，具有特有的清新气味，不会给使用者带来不适。
