Description
技术领域
本发明涉及新材料技术领域，具体涉及一种柔软无纺布贴合PVC树脂发泡膜及其制备方法和应用。
背景技术
软质PVC片材透明美观、质地柔软，已被广泛用于日用制品领域，如台布、桌垫和发泡地毯等。这类制品一般是在印刷图案的另一面附上透明膜，既可以显示透明膜上的印刷图案，又可以透过透明膜观察到家具的形貌，起到很好的装饰效果。但片材不抗拉，整体性能较差。
目前市面上流行印花、素色等风格的地毯系列产品，产品在使用中由于PVC树脂发泡膜出现不柔软，不耐寒，不防滑等问题。
发明内容
为了克服现有技术中存在的缺点和不足，本发明的目的在于提供一种柔软无纺布贴合PVC树脂发泡膜，该PVC树脂发泡膜不易风化，不易撕裂与破损且更耐用，具有超柔软，高弹性，舒适度好等优点。
本发明的另一目的在于提供一种柔软无纺布贴合PVC树脂发泡膜的制备方法，该制备方法简单，后续成型速度快，利于工业化生产。
本发明的再一目的在于提供一种柔软无纺布贴合PVC树脂发泡膜的应用，通过热压片将PVC树脂发泡膜附着在拉绒布上面经热压贴合形成片材卷料，取代以前挤出切片成型工艺，产品弹性更强，延长了防滑地毯的使用寿命，利用其制得印花发泡地毯具有高抗拉、不易风化、减缓降解时间、产品更经久耐用的特点。
本发明的目的通过下述技术方案实现：一种柔软无纺布贴合PVC树脂发泡膜，包括如下重量份的原料：
所述活性碳酸钙采用经马来酸酐接枝苯乙烯异戊二烯-苯乙烯嵌段共聚物处理过的纳米活性碳酸钙；每份所述树脂粉为PVC树脂粉。所述PVC树脂粉为PVC糊状树脂粉WB-33、1125PVC糊状树脂粉和PVC树脂粉-1311中的至少一种；更优选的，每份所述PVC树脂粉是由1125PVC糊状树脂粉、PVC糊状树脂粉WB-33和PVC树脂粉-1311按照重量比为0.8-1.0:1.0:0.6-1.0组成的混合物。
本发明中的PVC树脂发泡膜不易风化，不易撕裂与破损且更耐用，具有超柔软，高弹性，舒适度好等优点。其中采用的PVC树脂粉分子量越高，膜产品的拉伸强度、冲击强度、弹性模量越高，可以使制得的PVC树脂发泡膜具有较高的强度；而DOP为油环保增塑剂，可以降低PVC树脂粉分子链间的作用力，使PVC树脂粉的玻璃化温度、流动温度与所含微晶的熔点均降低，增塑剂可提高树脂的可塑性，使制品柔软、耐低温性能好；而硬脂酸的使用可以使材料在加工过程中具有很好的分散性、相容性和加工流动性，使材料热稳定性优良，具有高效耐候性；热稳定剂的加入能使材料在加工过程中有很好的分散性、相容性和加工流动性，使材料热稳定性优良，具有高效耐候性和阻燃性能；而其中采用的颜料粉具有很好的抗黄效果，活性碳酸钙可以提高柔软无纺布贴合PVC树脂发泡膜的强度和耐高温性能，与PVC树脂粉具有良好的相容性是发挥其作用和控制添加量的关键，本发明通过采用经马来酸酐接枝苯乙烯异戊二烯-苯乙烯嵌段共聚物处理过的纳米活性碳酸钙，可以提高超纳米活性碳酸钙与PVC树脂粉的相容性，从而提高制得PVC树脂发泡膜的强度。
优选的，每份所述发泡助剂包括如下重量份的原料：

S1、按照重量份，将偶氮发泡剂以及硬脂酸锌与乙二醇混合，加热至70-80℃，以300-400r/min的速率搅拌60-90min，得到混合物A，备用；
S2、按照重量份，将三硬脂酸酯甘油酯加入步骤S1中得到的混合物A中，加热至60-80℃搅拌40-60min，降温调节混合液的黏度，加入脂肪酸聚氧乙烯醚硫酸钠再在400-600r/min的速率下常温搅拌20-40min，消泡后得到发泡助剂成品。
本发明中采用的发泡助剂通过采用上述原料制得，利用上述原料以及制备方法制得发泡助剂简单，受热时分解平缓，发出热量少，发泡效果明显的优点，同时不影响发泡剂低温下的热稳定性，有利于低温条件下充分的塑炼，使之能够在压延过程中平稳较快分解形成泡孔，泡孔结构较为稳定，塌陷情况得到显著改善。
优选的，每份所述耐寒剂为PVC耐寒柔软剂，所述PVC耐寒柔软剂优选石家庄冠驰化工科技有限公司的PVC耐寒柔软剂。
本发明中采用的PVC耐寒柔软剂可抑制DOP油增塑剂析出、耐低温(零下40度保持耐寒柔软性)、热稳定性提高，可以使制得的PVC树脂发泡膜的低温柔韧性得到提高，强附着力，热稳定性、抗冲击性和改善流动性更高，耐腐蚀更强，显著提升了PVC树脂发泡膜的综合性能。
优选的，每份所述热稳定剂为粉体钙锌稳定剂和PVC复合稳定剂中的至少一种；所述PVC复合稳定剂优选高邑县恒鑫化工有限公司生产的。
本发明中所采用的热稳定剂能使PVC树脂发泡膜的原材料在加工过程中有很好的分散性、相容性和加工流动性，使材料热稳定性优良，具有高效耐候性和阻燃性能。
优选的，每份所述颜料粉为炭黑、群青色粉和酞青蓝中的至少一种。
本发明还提供了一种柔软无纺布贴合PVC树脂发泡膜的制备方法，通过如下步骤制得：
1)原料准备：按原料组成称取各原料，混合得到混合物A；

由具体实施例3和对比例1的对比可知，优选的本申请中填充剂的用量可以提升材料的抗风化性能；由具体实施例3和对比例2的对比可知，优选的在制备发泡助剂的原料中添加三硬脂酸酯甘油酯，可以提升材料的耐热和耐候性能。本发明制得的柔软无纺布贴合PVC树脂发泡膜具有很好的高耐寒、防滑阻燃、感湿变色、印花图案类型丰富、色彩更艳丽多样的特点，而且还具有产品质量稳定、图案精美、手感舒适，环保无毒可以给消费者新颖、超值感觉，实现了金膜与立体印花结合，而上述制备方法简单，后续成型速度快，利于工业化生产。
上述实施例为本发明较佳的实现方案，除此之外，本发明还可以其它方式实现，在不脱离本发明构思的前提下任何显而易见的替换均在本发明的保护范围之内。
