Description

地板保护专用防潮防水珍珠棉保护膜
技术领域
本发明属于珍珠棉保护膜技术领域，具体涉及一种地板保护专用防潮防水珍珠棉保护膜。
背景技术
珍珠棉又叫聚乙烯发泡棉，聚乙烯发泡棉是非交联闭孔结构，英文简称EPE，珍珠棉是一种新型环保的包装材料，它由低密度聚乙烯脂经物理发泡产生无数的独立气泡构成，聚乙烯发泡棉克服了普通发泡胶易碎、变形、恢复性差的缺点，具有隔水防潮、防震、隔音、保温、可塑性能佳、韧性强、循环再造、环保和抗撞力强等诸多优点，亦具有很好的抗化学性能，发泡聚苯乙烯包装制品使用后无法回收，造成白色污染，被国际禁用，因此聚乙烯发泡棉是传统包装材料的理想替代品珍珠棉具有可回收性，因此应用较为广泛。
由于珍珠棉是高发泡成形产品，重量轻，有一定坚固性柔软性和缓冲性很好，导热率很低隔热性很优，独立气泡的泡沫材，是几乎没有吸水性的防水材；但是目前传统的发泡珍珠棉还存在防潮性能和防水性能不佳的问题，使用范围受到限制，因此还需对其进行研究。
针对上述技术问题，故需要进行改进。
发明内容
本发明是为了克服上述现有技术中的缺陷，针对传统的珍珠棉防潮和防水性能不佳的问题，提供一种地板保护专用防潮防水珍珠棉保护膜。
为了达到以上目的，本发明所采用的技术方案是：地板保护专用防潮防水珍珠棉保护膜，包括保护膜层、珍珠棉和涂覆层；保护膜层设置有两层，分别布设于珍珠棉的上下端，所述保护膜层和珍珠棉之间通过相互热压连接，所述涂覆层通过压辊压合后与保护膜层和珍珠棉牢固粘合，所述保护膜层为PE保护膜，所述珍珠棉为EPE珍珠棉，所述EPE珍珠棉包括以下重量份的原料：聚乙烯100-155份、改性VAE乳液10-15份、钛酸酯改性碳酸钙10-19份、氢氧化铝3-7份、抗静电剂1-4份、发泡剂6-10份、内润滑剂1-5份、交联剂1-3份、硅烷偶联剂1-3份。

作为本发明的一种优选方式，所述PE保护膜的外侧均匀涂布有胶黏剂，所述PE保护膜的原料由重量比为1:0.05的LLDPE7042和LDPE2420D组成。
作为本发明的一种优选方式，所述LLDPE7042采用中石化扬子石油化工股份有限公司的熔融指数为1.7-2.3g/10min、密度为0.916-0.920g/cm3的LLDPE；所述LDPE2420D采用中海壳牌石油化工有限公司的熔融指数为0.24-0.26g/10min、密度为0.922-0.923g/cm3的LDPE。
作为本发明的一种优选方式，所述胶黏剂的包括以下重量份的原料：环氧树脂50-100份、固化剂15-25份，固化促进剂1-5份，乳化剂10-50份、过硫酸钾水溶液1-5份，其余为水；其中，环氧树脂和固化剂组分的质量比为1∶3。
作为本发明的一种优选方式，所述环氧树脂为由单一双酚A二缩水甘油脂聚合而成的环氧树脂。
作为本发明的一种优选方式，所述改性VAE乳液包括以下重量份材料：VAE 45-59份，聚乙烯醇5-7份，醋酸乙烯15-20份，过硫酸铵1-4份，过硫酸钾1-3份。
作为本发明的一种优选方式，所述改性VAE乳液包括以下重量份材料：VAE 50份，聚乙烯醇7份，醋酸乙烯20份，过硫酸铵4份，过硫酸钾3份。
作为本发明的一种优选方式，所述发泡剂为偶氮二甲酰胺，二亚硝基五亚甲基四胺或4,4'-氧代双苯磺酰肼中的任意一种。
作为本发明的一种优选方式，所述硅烷偶联剂为硅烷偶联剂KH-550或硅烷偶联剂KH-560中的任意一种。
本发明的有益效果是：
1.珍珠棉上设置保护膜层，保护膜层为PE保护膜，增加了珍珠棉的强度，提高了整体的抗拉性能，且保护膜层与珍珠棉结合，提高了珍珠棉的防水防潮水效果；
2.在EPE珍珠棉中添加改性VAE乳液，能够改善珍珠棉与保护膜层连接的稳定性，在反应过程中会使得乳胶粒表面电荷增加，乳胶粒间相互排斥作用增强，相互聚结减少，使体系稳定。
3.PE保护膜的原料由LLDPE7042和LDPE2420D组成，它与特定配方的胶黏剂进行配合使用，大大增大了PE保护膜与珍珠棉的粘结力，同时，在PE保护膜的外侧均匀涂布有胶黏剂，保证了防水防潮作用的同时，也保持了良好的表面光滑性和耐磨性。
