Description

一种高韧性防水墙纸及其制备方法
技术领域
本发明涉及墙纸领域，尤其涉及一种高韧性防水墙纸及其制备方法。
背景技术
墙纸，也称为壁纸，是一种用于裱糊墙面的室内装修材料，广泛用于住宅、办公室、宾馆、酒店的室内装修等。材质不局限于纸，也包含其他材料。因为具有色彩多样、图案丰富、豪华气派、安全环保、施工方便、价格适宜等多种其它室内装饰材料所无法比拟的特点，故在欧美、日本等发达国家和地区得到相当程度的普及。壁纸分为很多类，如覆膜壁纸、涂布壁纸、压花壁纸等。通常用漂白化学木浆生产原纸，再经不同工序的加工处理，如涂布、印刷、压纹或表面覆塑，最后经裁切、包装后出厂。具有一定的强度、韧度、美观的外表和良好的抗水性能。
现有技术中墙纸的韧性和防水性能无法满足实际使用时的需求，因此亟需设计一种高韧性防水墙纸来解决现有技术中的问题。
