一种加强型泡沫胶带及其制备方法
技术领域
本发明属于包装技术领域，涉及一种泡沫胶带及其制备方法，特别是涉及一种加强型泡沫胶带及其制备方法。
背景技术
在日常生活中，随处可见张贴于墙面、玻璃、塑料、水泥柱上的海报、广告、招聘信息、安全标示等等。而传统所用的粘接物为双面胶带或者一些不带基材的胶体，多数只能使用一次，粘贴后容易产生残胶或者粘死问题。胶和需固定物也都不能回收重复使用，且容易对被贴材料(墙面、玻璃、塑料、水泥柱等)形成污染，甚至刚贴完发现贴错、贴歪都不能更正，同时也产生了大量的垃圾且较高的费用。
而带基底层的此类泡沫胶带在贴合一些大角度、或者不规则的不平的曲面时容易产品翘口和贴和不牢固等问题。而近期所用的一些无基底层的单面泡沫胶带对泡沫的发泡倍率和厚度又有较高的要求，发泡倍率大剥离时很容易基材破坏，而厚度太厚或太薄又较难剥离和重工，且在冲型加工或使用过程中容易变形，甚至因被固定物重量过大而使泡沫层断裂等问题。
为了解决上述现有技术的不足，急需发明一种加强型泡沫胶带及其制备方法。
发明内容
