其中吸水粘合剂制备过程如下:将氧化淀粉加入水中制备成淀粉糊,搅拌分散均匀后升温至40℃,然后向其中加入2,3-环氧丙基三甲基氯化铵,恒温反应5h,然后过滤洗涤干燥得到吸水粘合剂;每克氧化淀粉中加入0.12-0.13g2,3-环氧丙基三甲基氯化铵;由于氧化淀粉中含有羧基和羟基,能够与2,3-环氧丙基三甲基氯化铵中的环氧基团发生开环反应,进而使得2,3-环氧丙基三甲基氯化铵接枝在氧化淀粉链上,进而使得氧化淀粉上接枝有季铵盐基团,由于季铵盐基团具有较高的吸水性能,进而使得制备的氧化淀粉具有较高的吸水性能;
第二步,将第一步中粘合后的铝箔纸通过调压式复合机压合,得到可回收铝箔纸;
进一步地,调节式复合机包括两个相对设置且呈竖直分布的支撑板,两个支撑板之间从上到下依次安装固定有顶接板、滑动承载座和底撑轴;
支撑板的侧壁中部开有条形卡孔,同时滑动承载座包括承载板,承载板的两端侧壁均一体连接固定有与条形卡孔配合的条形卡块,承载板的表面中部两侧均开有条形滑动孔,两个条形卡块的端面均开有与条形滑动孔相连通的第一螺纹孔,两个第一螺纹孔中均安装有调节螺杆,两个条形滑动孔中均滑动安装有滑动块,滑动块的侧壁开有安装槽,安装槽中安装有轴承,调节螺杆的一端安装在轴承中,滑动块的两端侧壁分别与条形滑动孔的侧壁相接,同时滑动块的表面中心处开有第一限位孔,第一限位孔中滑动安装有第一压动杆,第一压动杆的顶端面一体连接固定有第一挡块,第一压动杆上套设有第一压簧,第一压簧的顶端面与第一挡块的底端面压紧相接,底端面与滑动块的表面压紧相接,同时第一压动杆的底端连接固定有边压柱;承载板的表面中心处一体连接固定有固定块;固定块的表面中心处开有第二限位孔,第二限位孔中滑动安装有第二压动杆,第二压动杆的顶端面一体连接固定有第二挡块,第二压动杆上套设有第二压簧,第二压簧的顶端面与第二挡块的底端面压紧相接,底端面与固定块的表面压紧相接,同时第二压动杆的底端连接固定有在中压柱,中压柱的两端面分别与边压柱的端面相接。
进一步地,支撑板的侧壁底部开有第一转动孔,第一转动孔中安装有轴承底撑轴的两端安装在轴承中,同时底撑轴的一端与第一减速电机的动力输出端相连接。
进一步地,滑动块相对的两侧壁顶端一体连接固定有卡接条,滑动块通过卡接条卡接在承载板的表面,卡接条与固定条的厚度相同。
进一步地,第一压簧和第二压簧完全相同,第一压动杆和第二压动杆的质量完全相同,同时第二挡块和第一挡块的质量也完全相同,第一压动杆的长度大于第二压动杆的长度0.05-0.06mm,边压柱和中压柱完全相同,边压柱和中压柱的侧壁外表面分别开有深度相同的第一螺纹槽和第二螺纹槽,第一压动杆和第二压动杆的底端侧壁外表面分别开有与第一螺纹槽和第二螺纹槽螺纹配合的外螺纹,边压柱和中压柱通过螺纹连接固定在第一压动杆和第二压动杆的底部。
进一步地,顶接板的表面中心处开有第二转动孔,第二转动孔中安装有升降螺杆,升降螺杆上通过螺纹连接固定有压紧板,压紧板的表面中心处开有与升降螺杆螺纹配合的第二螺纹孔,同时压紧板的两端面分别与两个支撑板的侧壁内表面相接,升降螺杆的顶端穿过第二转动孔与第二减速电机的动力输出端相连接。
本发明的有益效果:
本发明通过在铝箔层和纸基层之间复合一层网格布,由于粘合剂粘合在网格布上,粘合剂呈网状分布,在与铝箔层和纸基层之间进行复合后粘合剂呈网状分布在纸基层和网格布之间以及网格布与铝箔层之间,不仅实现粘合剂分布均匀,使得铝箔纸粘合均匀,并且粘合剂没有全部覆盖,回收铝箔纸时容易剥离,解决了现有技术中铝箔纸回收时剥离困难的问题。
本发明在铝箔纸粘合后通过调压式复合机进行对铝箔纸进行压合,由于两侧的边压柱施加的压力大于中部的中压柱施加的压力,使得两边侧的铝箔纸压制紧密,而中部稍微施加压力压合,进而使得制备的铝箔纸两边侧粘合牢固防止开胶,而中部则轻微压合,粘合不紧密,并且由于制备的吸水粘合剂具有较高的吸水性能,在热水中吸水膨胀,并且由于铝箔纸中部压合力较小,并且由于铝箔层表面光滑,当粘合剂膨胀时造成中部的网格布与铝箔层分离,而铝箔纸两侧网格布与铝箔层之间膨胀粘合力下降,从中间向两边将网格布和纸基从铝箔层上揭完好可以直接重复使用。
本发明在铝箔层和纸基层之间设置网格布,同时网格布是由玻璃纤维制备,能够提高制备的铝箔纸的强度。

顶接板2的表面中心处开有第二转动孔21,第二转动孔21中安装有升降螺杆5,升降螺杆5上通过螺纹连接固定有压紧板6,压紧板6的表面中心处开有与升降螺杆5螺纹配合的第二螺纹孔61,同时压紧板6的两端面分别与两个支撑板1的侧壁内表面相接,升降螺杆5的顶端穿过第二转动孔21与第二减速电机的动力输出端相连接;
该调节式复合机的具体工作过程如下:
第一步,将粘合后的铝箔纸放置在底撑轴4侧壁外表面顶部;
第二步,控制第二减速电机工作带动升降螺杆5转动,带动压紧板6向下移动,直到压紧板6的底面同时与第一挡块341和第二挡块371的表面相接时,继续控制压紧板6向下移动,同时对第一压动杆34和第二压动杆37的顶端施加相同的压力时,第一压动杆34和第二压动杆37向下移动,第一挡块341和第二挡块371同时向下移动,并对第一压簧35和第二压簧38施加相同的压力,直到边压柱36与铝箔纸的表面相接触,此时由于第一压动杆34的长度大于第二压动杆37的长度0.05-0.06mm,再向下压动0.05-0.06mm时中压柱39与铝箔纸表面相接,此时边压柱36已经压动铝箔纸的两边侧表面纸基向铝箔层移动0.05-0.06mm,并且在然后再向下压动0.01mm时,中压柱39压动铝箔纸的中部表面纸基向铝箔层移动0.01mm,而两边侧纸基向铝箔层移动又移动0.01mm,使得两边侧的铝箔纸压制紧密,而中部稍微施加压力压合,进而使得制备的铝箔纸两边侧粘合牢固防止开胶,而中部则轻微压合,粘合不紧密,在回收铝箔纸时中部很容易撕开;
第三步,控制第一减速电机工作,通过第一减速电机带动底撑轴4转动,底撑轴4转动过程中带动压合后的铝箔纸向外输出,同时输出的铝箔纸卷绕制早成卷机上卷制成卷,并且通过成卷机卷制可以拉动铝箔纸向外输出;
第四步,当制备的铝箔纸宽度较小时,更换相同且长度较小的边压柱36和中压柱39,然后转动两侧的调节螺杆32,调节螺杆32通过第一螺纹孔313的螺纹连接作用在第一螺纹孔313中移动,带动滑动块33沿条形滑动孔312向中部移动,直到两个边压柱36的一端面与中压柱39的两端面均压紧相接,同理,当制备的铝箔纸宽度较大时,更换相同且长度较大的边压柱36和中压柱39进行工作。
实施例4:
铝箔纸的回收过程如下:
将铝箔纸浸泡在60℃的热水中浸泡5h,此时由于制备的吸水粘合剂具有较高的吸水性能,在热水中吸水膨胀,并且由于铝箔纸中部压合力较小,并且由于铝箔层表面光滑,当粘合剂膨胀时造成中部的网格布与铝箔层分离,而铝箔纸两侧网格布与铝箔层之间膨胀粘合力下降,从中间向两边将网格布和纸基从铝箔层上揭下,铝箔层完好可以直接重复使用。
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。
