Description

聚氨酯仿真花及其制备方法
技术领域
本发明属于化工领域，具体涉及一种聚氨酯仿真花及其制备方法。
背景技术
聚氨酯仿真花是市场上用聚氨酯材质做成的花，假得可以乱真，而且，这种“真”不只是视觉上的真，连触觉、嗅觉都跟真花极为相似。仿真花的工艺也不断发展变化，纸、布、绢、纱、绒等材料不断地应用在假花制作上，更真、更像可说是仿真花的目标所在。随着新材料的应用，这一目标正在被实践着。
聚氨酯仿真花具有以下优点：聚氨酯材料仿真花的工艺：一瓣一瓣的花瓣通过模具像挤牙膏似的直接挤出来，然后剪裁、上色、上胶、粘贴。目前市场上现有的仿真花存在成型度差、花叶表面有碎屑脱落等问题。
发明内容
针对现有材料的缺点，本发明的目的是提供一种聚氨酯仿真花，具有加工工艺简单，生产效率高，能耗低，所做制品不怕水洗，仿真度高、花叶表面无碎屑脱落等优点；本发明还提供其制备方法，工艺合理，制备方法简单易实施。
本发明所述的聚氨酯仿真花，由A组分和B组分按照以下重量份数制成：
A组分：
B组分：
改性黑料    30～35份；
其中：改性黑料为NCO含量为28％的改性黑料。
其中：
官能度为3、分子量为6000的聚醚多元醇优选为聚醚多元醇DEP-330G，由淄博德信联邦化学工业有限公司生产。官能度为3、分子量为8000的接枝聚醚多元醇为聚醚多元醇POP-36/28，由淄博德信联邦化学工业有限公司生产。采用这两种聚醚多元醇，制备得到的制品具有表面结皮好、无褶皱、脱模时间快、制品手感好、硬度大等优点。
泡沫稳定剂为泡沫稳定剂201，迈图高新材料有限公司生产，具有稳定泡沫和调节泡孔，乳化泡沫物料的作用。
胺催化剂为胺催化剂A33，美国气体化工产品公司生产，利用其高活性对凝胶反应和发泡反应起到较强的催化作用。
交联剂为二乙醇胺，在稳定泡沫结构的同时对聚氨酯反应有一定的催化作用。
扩链剂为1,4-丁二醇，把反应中的分子链进一步扩大，增加制品的柔韧性。
改性黑料为用官能度为2、分子量为600的聚醚多元醇和黑料PM200按重量比为20-35：80-95在80-90℃下反应2-3小时得到的NCO含量为28％的改性黑料。采用该改性黑料作为原料能够增加制品的表面光滑性和韧性等。
所述的聚氨酯仿真花的制备方法，包括以下步骤：
将A组分各原料加入搅拌器混合均匀，调整恒定料温23-27℃，调节搅拌器转速到4000-5000r/min，将预热至23-27℃的B组分倒入A组分中搅拌15-25秒，将混合物料倒入预热至35-45℃的模具中，5-10min后脱模，得到产品。
搅拌器转速为4000-5000r/min，采用此范围的转速可以更充分的混匀各组分料。
综上所述，本发明具有以下优点：
(1)本发明制作弧度大的花瓣造型，能做得栩栩如生，如马蹄莲、曼陀罗、魔鬼郁金香等。颜色凝固度好于绢花；具有与真花一样的触感，触摸手感好，触摸后不留任何痕迹，所做制品不怕水洗；生产效率高，能耗低，所做制品不怕水洗，具有仿真度高、花叶表面无碎屑脱落等优点。
(2)在制作过程中，聚氨酯材料的仿真花可加入香精，让花朵有着真花的香味。
(3)本发明还提供其制备方法，工艺合理，制备方法简单易实施。
