Description
技术领域
本发明涉及一种包装材料,特别是一种保温箱的板材结构及其制备方法。
背景技术
保温箱大多由外壳和填充在外壳内部的发泡材料构成,由于发泡材料多为强极性高分子材料,例如聚氨酯,而外壳多为非极性高分子材料,例如聚乙烯,所以发泡剂固化后形成的保温层对外壳的附着力不强,从而容易导致作为保温层与外壳分离,影响保温箱的保温效果。
为了解决上述问题,技术人员通过对外壳的内侧喷线性低密度聚乙烯小颗粒,制造粗糙表面,从而有利于聚氨酯的附着,但是喷粉操作难以保证覆盖均匀,喷粉过多或过少均不利于聚氨酯的附着,而且此方法增大的比表面积十分有限,因此聚氨酯的附着力依然不高,脱层现象依然存在。
发明内容
为了克服现有技术的不足,本发明提供一种结构紧密、保温效果好的保温箱的板材结构及其制备方法。
本发明解决其技术问题所采用的技术方案是:
一种保温箱的板材结构,包括保温层和设置在保温层两侧的外表层,所述外表层的外侧为光滑的平面,内侧固定有单通多孔阳极氧化铝膜,所述单通多孔阳极氧化铝膜包括封闭面和开口面,所述开口面布满单侧开口且开口方向一致的小孔,所述小孔与保温层相接触。
所述单通多孔阳极氧化铝膜的厚度3-5微米。
所述小孔的孔径为600-800纳米。
所述小孔的孔深为1-2微米。
所述外表层由聚乙烯、辅助树脂和增强剂制成,三者之间的质量比为100:1-2:0.1-0.6。
所述辅助树脂为聚乳酸、聚碳酸酯、聚酰胺中的一种或一种以上任意比例的混合物。
所述增强剂为硫酸钡、碳酸钙、硫酸钠中的一种或一种以上任意比例的混合物。
所述保温层由聚氨酯发泡剂熟化形成。
一种制备所述保温箱的板材结构的方法,步骤如下:
1)按照实际需求剪裁铝箔,用丙酮和乙醇分别超声波震荡清洗5分钟,然后用浓度为0.5-1.0mol/L的氢氧化钠溶液浸泡至表面有气泡析出;
2)对步骤1)处理后的铝箔进行电化学抛光直至表面呈镜面光滑,电压为12伏,抛光液为高氯酸与乙醇的混合溶液,所述高氯酸与乙醇的体积比为1:1;
3)将步骤2)处理后的铝箔置于恒温水浴槽,温度20-25℃,同时设置搅拌器,搅拌速度为800r/min,以另一铝片作为对电极,电解液为1.5-2.0mol/L的硫酸溶液,电压25-30伏,氧化完成后以1.8%铬酸和6.0%磷酸的混合溶液浸泡除膜,即完成一次阳极氧化;
4)将步骤3)制得的铝箔再一次重复步骤3)的操作,即完成二次阳极氧化;
5)将电源的正负极对换,设置电压为15-20伏,使铝箔从铝基体上脱离,即制得单通多孔阳极氧化铝膜;
6)将所述聚乙烯、辅助树脂和增强剂加入搅拌机中,60-100r/min低速搅拌5-10分钟,即制得外表层原料;
7)将所述外表层原料加入热模具中,在300-350℃下凝固10分钟,然后放入步骤5)制得的单通多孔阳极氧化铝膜,使单通多孔阳极氧化铝膜的封闭面与其相接触,继续凝固5-10分钟,静置冷却,即制得固定有单通多孔阳极氧化铝膜的外表层;
8)在两个固定有单通多孔阳极氧化铝膜的外表层之间注入发泡材料,发泡温度20-25℃,启发时间为10-15s,固化时间为30-50s,8-24小时后完全熟化形成保温层,即制得所述保温箱的板材结构。
本发明的有益效果是:通过在外表层的内侧固定单通多孔阳极氧化铝膜,提供了一种比表面积极大的三维纳米结构,有利于保温层聚氨酯分子的附着,使保温层与聚乙烯外壳结合紧密,不易分离,有效提高保温箱的保温效果。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图。
具体实施方式
参照图1,一种保温箱的板材结构,包括保温层3和设置在保温层3两侧的外表层1,所述保温层3可用本领域常用的发泡剂熟化形成,以下实施例采用的发泡剂均为聚氨酯发泡剂,因为聚氨酯发泡剂形成的保温层具有超低温热传导率,耐热保温,防震抗压,防水防潮等多种优良特性。所述外表层1的主要制备原料是聚乙烯、辅助树脂和增强剂,三者之间的质量比为100:1-2:0.1-0.6,所述辅助树脂需玻璃化温度高于或等于聚乙烯,如聚乳酸、聚碳酸酯、聚酰胺中的一种或一种以上任意比例的混合物。聚乙烯由于添加了辅助树脂力学性能发生改变,因此需要添加少量增强剂补充强度,如硫酸钡、碳酸钙、硫酸钠中的一种或一种以上任意比例的混合物。
所述外表层1的外侧为光滑的平面,内侧固定有单通多孔阳极氧化铝膜2,所述单通多孔阳极氧化铝膜2的厚度3-5微米。所述单通多孔阳极氧化铝膜2包括封闭面和开口面,所述开口面布满单侧开口且开口方向一致的小孔,孔径为600-800纳米,孔深为1-2微米,所述小孔与保温层3相接触。单通多孔阳极氧化铝膜2是铝箔在酸性电解液中阳极氧化得到的,通过控制氧化条件(如电解液、电解电压等)可灵活地控制孔径及形貌。本发明最终制成的单通多孔阳极氧化铝膜2具有高密度的孔分布及细长的孔道,提供了一种比表面积极大的三维纳米结构,有利于保温层3的聚氨酯分子的附着,使保温层3与聚乙烯外壳结合紧密,不易分离,有效提高保温箱的保温效果。
实施例1:
一种保温箱的板材结构,包括保温层3和设置在保温层3两侧的外表层1,所述外表层1的外侧为光滑的平面,内侧固定有单通多孔阳极氧化铝膜2,所述单通多孔阳极氧化铝膜2的厚度3微米,所述单通多孔阳极氧化铝膜2包括封闭面和开口面,所述开口面布满单侧开口且开口方向一致的小孔,孔径为800纳米,孔深为1微米,所述小孔与保温层3相接触。
所述外表层1由聚乙烯、辅助树脂和增强剂制成,三者之间的质量比为100:2:0.6。所述辅助树脂为聚乳酸,所述增强剂为硫酸钡,所述保温层3由聚氨酯发泡剂熟化形成。
制备所述保温箱的板材结构的方法,步骤如下:
1)按照实际需求剪裁铝箔,用丙酮和乙醇分别超声波震荡清洗5分钟,洗去铝箔表面的油污,然后用浓度为0.5-1.0mol/L的氢氧化钠溶液浸泡至表面有气泡析出,除去天然氧化层;
2)对步骤1)处理后的铝箔进行电化学抛光直至表面呈镜面光滑,电压为12伏,抛光液为高氯酸与乙醇的混合溶液,所述高氯酸与乙醇的体积比为1:1;
3)将步骤2)处理后的铝箔置于恒温水浴槽,温度20-25℃,同时设置搅拌器,搅拌速度为800r/min,以保证恒温水浴槽内的温度分布均匀,以另一较大面积的铝片作为对电极,电解液为1.5-2.0mol/L的硫酸溶液,电压25-30伏,氧化完成后以1.8%铬酸和6.0%磷酸的混合溶液浸泡除膜,即完成一次阳极氧化;
4)将步骤3)制得的样品重复步骤3)的操作,即完成二次阳极氧化;
5)将电源的正负极对换,设置电压为15-20伏,利用析氢的鼓泡作用使铝箔从铝基体上脱离,即制得单通多孔阳极氧化铝膜2;
6)将所述聚乙烯、辅助树脂和增强剂加入搅拌机中,60-100r/min低速搅拌5-10分钟,即制得外表层原料;
7)将所述外表层原料加入热模具中,在300-350℃下凝固10分钟,先接触到热模具的聚乙烯被加热熔融粘附在热模具上,形成所述外表层1光滑的外侧,辅助树脂因其粒径比聚乙烯大,玻璃化温度高于或等于聚乙烯,因而熔融较慢,辅助树脂与未接触到热模具的聚乙烯均匀混合处于熔融不完全状态,此时放入步骤5)制得的单通多孔阳极氧化铝膜,使单通多孔阳极氧化铝膜2的封闭面与其相接触,继续凝固5-10分钟,静置冷却,即制得固定有单通多孔阳极氧化铝膜2的外表层1;
8)在两个固定有单通多孔阳极氧化铝膜2的外表层1之间注入聚氨酯发泡剂,发泡温度20-25℃,启发时间为10-15s,固化时间为30-50s,8-24小时后完全熟化形成保温层3,即制得所述保温箱板材。
实施例2:
一种保温箱的板材结构,包括保温层3和设置在保温层3两侧的外表层1,所述外表层1的外侧为光滑的平面,内侧固定有单通多孔阳极氧化铝膜2,所述单通多孔阳极氧化铝膜2的厚度5微米,所述单通多孔阳极氧化铝膜2包括封闭面和开口面,所述开口面布满单侧开口且开口方向一致的小孔,孔径为600纳米,孔深为2微米,所述小孔与保温层3相接触。
所述外表层1由聚乙烯、辅助树脂和增强剂制成,三者之间的质量比为100:1.5:0.35。所述辅助树脂为聚碳酸酯,所述增强剂为碳酸钙,所述保温层3由聚氨酯发泡剂熟化形成。
制备所述保温箱的板材结构的方法与实施例1相同。
实施例3:
一种保温箱的板材结构,包括保温层3和设置在保温层3两侧的外表层1,所述外表层1的外侧为光滑的平面,内侧固定有单通多孔阳极氧化铝膜2,所述单通多孔阳极氧化铝膜2的厚度4微米,所述单通多孔阳极氧化铝膜2包括封闭面和开口面,所述开口面布满单侧开口且开口方向一致的小孔,孔径为700纳米,孔深为1.5微米,所述小孔与保温层3相接触。
所述外表层1由聚乙烯、辅助树脂和增强剂制成,三者之间的质量比为100:1:0.1。所述辅助树脂为聚酰胺,所述增强剂为硫酸钠,所述保温层3由聚氨酯发泡剂熟化形成。
制备所述保温箱的板材结构的方法与实施例1相同。
以在市面购买的与实施例厚度相同的普通保温箱板材作为对照组,通过平板热导仪检测3个实施例和对照组的热传导系数。
检测结果:实施例1的热传导系数为0.022W/(m·K),实施例2的热传导系数为0.019W/(m·K),实施例3的热传导系数为0.020W/(m·K),对照组的热传导系数为0.043W/(m·K)。从数据可以看出3个实施例的热传导系数均小于对照组,说明本发明有效地提高了保温箱的保温性能。
以上的实施方式不能限定本发明创造的保护范围,专业技术领域的人员在不脱离本发明创造整体构思的情况下,所做的均等修饰与变化,均仍属于本发明创造涵盖的范围之内。
