Description
技术领域
本发明属于洗衣粉包装膜制备领域，涉及一种复合型高强度洗衣粉包装袋。
背景技术
洗衣粉是日常生活中的洗涤必需品，通常是封装在塑料包装袋中，防止洗衣粉撒漏或者潮解，在洗衣粉使用运输过程中通常是直接随意摔落堆积，因此洗衣粉包装袋就要求必须有较高的抗跌落性能和强度，否则容易破裂造成其中的粉体遗漏，但是现有的包装袋撕裂强度较低，不能满足需求，并且洗衣粉在不同领域和场合使用时，可能会经受长时间太阳照射，并且可能会长期处于高温环境中，容易造成洗衣粉包装袋老化变脆，容易撕裂，使得洗衣粉洒出。
发明内容
本发明的目的在于提供一种复合型高强度洗衣粉包装袋，是由高强度疏水薄膜、耐高温缓冲层和高强度疏水薄膜复合制备，高强度疏水薄膜本身具有较高的强度，三层复合后强度增大，同时通过耐高温缓冲层的支撑和缓冲使得包装袋耐跌落，在高处跌落时通过缓冲作用不会破裂，同时内外两层高强度疏水薄膜的设置能够有效防止水渗漏浸渍入包装袋内，使得包装袋内部的洗衣粉潮湿，并且由于中间的缓冲层是由多硅氧基二酚和甲醛交联制备，由于多硅氧基二酚中含有两个酚羟基，提供了大量的交联位点，在与甲醛交联时交联程度增大，进而提高了交联后生成的聚合物的强度，在三层复合后，提高了包装袋的强度，进而有效解决了现有的包装袋撕裂强度较低，抗跌落能力较低的问题。
本发明的目的可以通过以下技术方案实现：
一种复合型高强度洗衣粉包装袋，该包装袋的具体制备过程如下：
第一步：将水杨酸加入乙醚中搅拌溶解，然后向其中加入二氯亚砜，升温至70-80℃回流反应10-12h，然后将得到的产物溶液在90℃蒸发，除去其中未反应完全的二氯亚砜和溶剂乙醚，得到水杨酰氯；其中每克水杨酸中加入0.94-0.98g二氯亚砜；
第二步，将制备的水杨酰氯加入乙醚中搅拌溶解，然后向其中加入3-氨基丙基三乙氧基硅烷，搅拌反应2-3h，然后进行减压蒸馏，得到三乙氧基硅烷基苯酚，反应结构式如下；水杨酰氯和3-氨基丙基三乙氧基硅烷按照物质的量之比为1：1的比例混合；
第三步，将醋酸和浓硫酸按照体积比为1：4的比例混合形成的酸溶液加入反应容器中，降温至5℃，然后向反应容器中加入质量分数为37％的甲醛溶液和正己胺，搅拌反应30-40min后向反应容器中加入第二步中制备的三乙氧基硅烷基苯酚，然后升温至30℃混合反应6-7h，得到产物溶液，将得到的产物溶液加入冰水中搅拌有固体析出，然后进行过滤后将滤饼洗涤至中性，然后将滤液用氨水调节至中性，静置有固体析出，对析出的固体进行过滤水洗后与洗涤后的滤饼一起进行烘干，得到多硅氧基二酚；其中每克三乙氧基硅烷基苯酚中加入正己胺0.17-0.18g，加入质量分数为37％的甲醛溶液0.31-0.33g，加入酸溶液8-9mL，反应结构式如下所示；由于在芳香化合物中羟基为邻对位活性较强，同时酰胺基团的间位活性较强，通过两者的作用，使得三乙氧基硅烷基苯酚中的酚羟基对位具有较高的活性，能够与甲醛和正己胺发生反应，由于正己胺中含有两个活泼氢，能够与两个三乙氧基硅烷基苯酚进行反应，进而使得制备的产物中引入两个酚羟基；
第四步，将多硅氧基二酚加入乙醚中搅拌溶解，然后向其中加入氢氧化钠，搅拌溶解后向反应容器中分两次加入质量分数为37％的甲醛溶液，每次加入量相同，第一次添加后在20-30℃下搅拌反应1-2h，然后第二次添加，第二次添加后升温至80-90℃回流反应3-4h，冷却出料，得到粘度为4000mpa.s的聚合物，然后向制备的聚合物中加入石油醚、吐温-80和十二烷基苯磺酸，搅拌混合20-30min，然后将混合物均匀涂布在高强度疏水薄膜的表面，喷涂完毕后立即在涂布层的表面复合一层高强度疏水薄膜，得到三层夹心塑料膜，将得到的塑料膜在常温下固化2-3h，得到高强度耐跌落塑料膜，然后将高强度耐跌落塑料膜制备成包装袋；其中每克多硅氧基二酚中加入质量分数为37％的甲醛溶液6.83-6.85g，加入氢氧化钠0.1g，加入乙醚55-60mL；同时每100g聚合物中加入5.1-5.3g石油醚，加入2.3-2.4g吐温-80，加入十二烷基苯磺酸3.1-3.3g；包装袋是由高强度疏水薄膜、耐高温缓冲层和高强度疏水薄膜复合制备，高强度疏水薄膜本身具有较高的强度，三层复合后强度增大，同时通过耐高温缓冲层的支撑和缓冲使得包装袋耐跌落，在高处跌落时通过缓冲作用不会破裂，同时内外两层高强度疏水薄膜的设置能够有效防止水渗漏浸渍入包装袋内，使得包装袋内部的洗衣粉潮湿，并且由于中间的缓冲层是由多硅氧基二酚和甲醛交联制备，由于多硅氧基二酚中含有两个酚羟基，提供了大量的交联位点，在与甲醛交联时交联程度增大，进而提高了交联后生成的聚合物的强度，在三层复合后，提高了包装袋的强度；同时由于中间层中是由多硅氧基二酚和甲醛通过聚合发泡制备，制备的发泡聚合物中含有大量的硅氧烷键，进而大大提高了聚合物的耐高温性能和疏水性能，
其中高强度疏水薄膜是将高密度聚乙烯、低密度聚乙烯、抗氧化剂、分散剂、表面活性剂按照质量比为100：12.3-13.4：0.73-0.75：2.16-2.24：0.86-0.94的比例加入挤出后流延，得到高强度疏水薄膜；
抗氧化剂的具体制备过程如下：①将巯基琥珀酸加入水中搅拌溶解，然后向其中加入二氯亚砜溶液中，升温至70-80℃回流反应10-12h，然后将得到的产物溶液在90℃蒸发，此时未反应的二氯亚砜溶液分解，同时溶剂水蒸发，得到巯基琥珀酰氯；其中每克巯基琥珀酸中加入二氯亚砜1.67-1.69g，②将步骤①中制备的巯基琥珀酰氯和水加入反应容器中，搅拌溶解，然后向其中加入1-哌啶硫代羰胺，升温至60-65℃回流反应15-16h，然后经过减压蒸馏得到抗氧化剂；其中巯基琥珀酰氯和1-哌啶硫代羰胺按照物质的量之比为1：2的比例混合制备；巯基琥珀酰氯中的酰氯基团能够与1-哌啶硫代羰胺中的氨基进行反应，生成酰氯，由于巯基琥珀酰氯中含有两个酰氯基团，均能够与1-哌啶硫代羰胺中的氨基进行反应，进而使得制备的抗氧化剂中引入两个1-哌啶硫代羰胺，同时由于哌啶中的氮元素能够捕获过氧化物中的活性自由基，进而生成氮氧自由基，进而实现光稳定作用，但是已经生成的过氧化物在一定浓度下分解为新的自由基，又将推进自由基的氧化反应，此时由于抗氧剂中含有硫元素，能够使过氧化物转化为稳定的非自由基化合物，进而完全抑制材料的光氧化。
本发明的有益效果：
1、本发明制备的包装袋是由高强度疏水薄膜、耐高温缓冲层和高强度疏水薄膜复合制备，高强度疏水薄膜本身具有较高的强度，三层复合后强度增大，同时通过耐高温缓冲层的支撑和缓冲使得包装袋耐跌落，在高处跌落时通过缓冲作用不会破裂，同时内外两层高强度疏水薄膜的设置能够有效防止水渗漏浸渍入包装袋内，使得包装袋内部的洗衣粉潮湿，并且由于中间的缓冲层是由多硅氧基二酚和甲醛交联制备，由于多硅氧基二酚中含有两个酚羟基，提供了大量的交联位点，在与甲醛交联时交联程度增大，进而提高了交联后生成的聚合物的强度，在三层复合后，提高了包装袋的强度，进而有效解决了现有的包装袋撕裂强度较低，抗跌落能力较低的问题。
2、本发明制备包装袋时内外两层使用的高强度疏水薄膜中含有抗氧剂，抗氧剂中引入两个1-哌啶硫代羰胺，同时由于哌啶中的氮元素能够捕获过氧化物中的活性自由基，进而生成氮氧自由基，进而实现光稳定作用，但是已经生成的过氧化物在一定浓度下分解为新的自由基，又将推进自由基的氧化反应，此时由于抗氧剂中含有硫元素，能够使过氧化物转化为稳定的非自由基化合物，进而完全抑制材料的光氧化，实现较高的抗氧化性能，使得包装袋在常温下紫外光氧化时具有较高的抗氧化性能，在长时间太阳照射下其性能不会有太大变化。
3、本发明的包装袋的中部缓冲层中的含有的硅氧键稳定存在，不易被紫外光和臭氧所分解，具有较高的耐辐照和耐候能力，进而使得制备的包装袋在常温下耐候性较强，并且由于中间缓冲层中含有大量的硅氧烷键，进而提高了塑料袋的热稳定性能，使得包装袋在高温下老化时，其断裂强度没有太大变化，进而提高了包装袋的耐热老化和光老化性能，使得制备的包装袋能够抗高温老化。

表1实施例4-8中制备的洗衣粉包装袋的撕裂强度测定结果(N.m-1)
由表1可知，实施例4中制备的包装袋具有较高的撕裂强度，撕裂强度达到181.4N.m-1，由于高包装袋是在两层高强度疏水薄膜之间复合一层缓冲层，由于中间的缓冲层是由多硅氧基二酚和甲醛交联制备，由于多硅氧基二酚中含有两个酚羟基，提供了大量的交联位点，在与甲醛交联时交联程度增大，进而提高了交联后生成的聚合物的强度，在三层复合后，提高了包装袋的强度；同时高强度疏水薄膜中含有抗氧剂，抗氧剂中引入两个1-哌啶硫代羰胺，同时由于哌啶中的氮元素能够捕获过氧化物中的活性自由基，进而生成氮氧自由基，进而实现光稳定作用，但是已经生成的过氧化物在一定浓度下分解为新的自由基，又将推进自由基的氧化反应，此时由于抗氧剂中含有硫元素，能够使过氧化物转化为稳定的非自由基化合物，进而完全抑制材料的光氧化，实现较高的抗氧化性能，使得包装袋在常温下紫外光氧化时具有较高的抗氧化性能，并且中部缓冲层中的含有的硅氧键稳定存在，不易被紫外光和臭氧所分解，具有较高的耐辐照和耐候能力，进而使得制备的包装袋在常温下耐候性较强，并且由于中间缓冲层中含有大量的硅氧烷键，进而提高了塑料袋的热稳定性能，在高温下老化时，其断裂强度没有太大变化；并且实施例5中由于制备的三乙氧基硅烷基苯酚中只有一个酚羟基，进而使得制备的产物聚合程度较低，降低了其撕裂强度，同时其中的缓冲层中含有的硅氧烷键含量降低，进而使得其耐热性能降低，在高温下抗撕裂强度降低，而实施例6中由于高强度疏水薄膜制备过程中添加的抗氧剂中硫元素含量降低，进而使得过氧化物的转化性能降低，进而降低了其耐光老化性能，同时实施例7中直接通过酚醛树脂复合高强度疏水薄膜，其中不含有硅氧烷键，造成中间层的抗氧化性能降低，热稳定性能也降低，同时实施例9直接使用高强度疏水薄膜制备包装袋，其中不含有硅氧烷键，进而使得其热稳定性降低，高温下容易老化降低了其撕裂强度。
以上公开的本发明优选实施例只是用于帮助阐述本发明。优选实施例并没有详尽叙述所有的细节，也不限制该发明仅为所述的具体实施方式。显然，根据本说明书的内容，可作很多的修改和变化。本说明书选取并具体描述这些实施例，是为了更好地解释本发明的原理和实际应用，从而使所属技术领域技术人员能很好地理解和利用本发明。本发明仅受权利要求书及其全部范围和等效物的限制。
