Description

一种可降解承重卡板及其制备方法
技术领域
本发明涉及航空运输用承重卡板技术，特别是涉及一种可降解承重卡板及其制备方法。
背景技术
现有技术中的卡板有木卡板、 铁卡板、免检卡板、消毒卡板、免熏蒸卡板、塑料卡板及镀铬卡板等。卡板具备运输的功能，且越来越多地应用在航空运输上。在飞机产品的装配工装型架上卡板的设计与制造过程中，经常遇到多站位大尺寸，各站位外形相同或类似，各站位有相同或类似元件的卡板的设计与制造。现有技术通常在各站位均设置卡板，卡板上设置工作元件(定位器、压紧器等)，卡板需要起吊，有时还需设计与制造卡板放置架，这种结构的卡板使用不方便，起吊存在安全隐患，存放占用厂房空间大，因此这种结构的卡板成本较高。
例如，申请号为 201510076439.7 的专利公开了一种发泡栈板及其制作方法所述栈板脚由牛皮纸或 PVC 材料的外壳包裹 PU 硬质发泡材料发泡成型制作而成，所述栈板脚的 PU 硬质发泡材料向上延伸出与栈板本体衔接用的预留衔接体，由牛皮纸包裹 PU 硬质发泡材料形成的栈板本体将栈板脚上的预留衔接体包裹，整体发泡成型从而形成带栈板脚的发泡栈板。所述栈板脚上的预留衔接体带有倒勾；其包括两部分，分别为：位于栈板脚顶部的凸台，以及位于栈板脚侧部的倒勾；所述凸台上设置有环型卡槽。但是，该申请所使用的栈板脚和栈板本体是分离的，使用时间长时，容易造成分裂，影响使用寿命。另外，栈板质量重，有航空运输经验的人都知道，货物的重量越重，运费也就越高，因此，如果能够减轻货物的重量，将为企业减少大量运输成本。
另外，现有技术中的卡板不容易降解，造成环境污染大，且回收成本较高。
发明内容
本发明的目的在于克服现有技术的不足，提供一种可降解承重卡板及其制备方法，重量轻，承重能力强，防滑耐磨，易于自然降解及回收。
为了达到上述目的，本发明采用的技术方案是：一种可降解承重卡板，包括上盖、填充料中层及下盖，所述下盖的底部设置若干个卡板支撑脚，所述下盖与若干个卡板支撑脚一体成型，填充料中层填充设置于下盖及若干个卡板支撑脚的内部，上盖盖合于填充料中层及下盖上方，所述卡板支撑脚的剖面设置为倒梯形。
作为本发明的较佳实施例，本发明所述下盖的底部设至少三排卡板支撑脚，每排至少设置三个卡板支撑脚，所述卡板支撑脚底端中部设置下沉凹槽，每排的卡板支撑脚之间设有一连接板，连接板卡装于下沉凹槽内。
作为本发明的较佳实施例，本发明所述连接板的外表面设置防滑波浪纹。
作为本发明的较佳实施例，本发明所述卡板支撑脚的剖面设置为倒梯形，靠近下盖底部一端的长度大于远离下盖底部另一端的长度，所述倒梯形的倾斜角设置为 30-60度。
作为本发明的较佳实施例，本发明所述上盖及下盖采用 PET 材料制成。
作为本发明的较佳实施例，本发明所述上盖及下盖的外表面分布设置防滑波浪纹。
作为本发明的较佳实施例，本发明所述上盖与填充料中层之间还设置一 IC 芯片，上盖上设置一显示窗，IC 芯片嵌装于显示窗内。
作为本发明的较佳实施例，本发明所述填充料中层由以下质量份的组分制备而成：
聚醚多元醇 4110 0.5-0.7 份；
聚醚多元醇 635 0.1-0.2 份；
聚醚多元醇 380 0.03-0.05 份；
双胺醚溶液 0.0003-0.0005 份；
N,N-二甲基环己胺 0.003-0.006 份；
六氢三嗪催化剂 0.002-0.003 份；
C18 季铵盐催化剂 0.008-0.01 份；
DBU 季铵盐催化剂 0.00008-0.0001 份；
硅油 0.016-0.018 份；
环戊烷 0.116-0.120 份；
PAPI 多亚甲基多苯基多异氰酸酯 1.3-1.4 份。
作为本发明的较佳实施例，本发明所述双胺醚溶液的浓度质量百分比是 60-80%。
本发明还公开了一种制成所述的可降解承重卡板的制备方法，步骤如下：
S1、制作下盖和若干个卡板支撑脚一体成型的模具，采用 PET 材料制作成卡板下盖；
S2、制作上盖的模具，采用 PET 材料制作成卡板上盖；
S3、制作填充料中层的材料，将各组分按照质量比称重后混合搅拌均匀；
S4、将下盖置于水平操作台上，将步骤 S3 混合搅拌均匀的材料均匀注入下盖内，在注入时首先注入各个卡板支撑脚，然后再注入下盖内，平齐下盖时停止注入；
S5、待填充料中层成型后，将上盖扣合于下盖上。
作为本发明的较佳实施例，本发明所述上盖与下盖之间通过粘贴固定。
与现有技术相比，本发明的有益效果是：设置上盖、填充料中层及下盖，下盖的底部设置若干个与下盖一体成型的卡板支撑脚，填充料中层填充设置于下盖及若干个卡板支撑脚的内部，通过设置一体成型的结构，增加稳固性及承重强度，避免因较大外力造成突然出现断裂或者松动的情况；卡板支撑脚设置为剖面为倒梯形，且角度可设置为 30-60 度，从工程力学的角度来讲，能够实现较轻的重量，承载较重的物品；在卡板支撑脚之间设置连接板，能够增强承载能力，防止断裂，延长使用寿命；填充料中层所采用的材料为环保材料，在具有较强的支撑能力，增强产品韧性、表面硬度及防折断应力，整个产品仅重 2.8-3KG，承重能力可达到1000-3600KG，为木质卡板的 1/2 到 1/4，重量轻，为目前相同重量承重最大的卡板，特别适用于航空运输，节约成本，提高了载重强度；填充料中层为环保材料，上盖和下盖采用 PET 材料，均为环保材料，易于自然降解及回收，避免了环境污染，不再使用后直接进行掩埋，一年左右可实现完全降解；在支撑脚之间设置连接板，增加稳固性；设置 IC芯片，具有记忆功能，能够随时扫描追踪卡板的位置信息。

具体实施方式
本发明的主旨在于克服现有技术的不足，提供一种可降解承重卡板及其制备方法，承重能力强，质量轻，不易折断，能够实现自动降解，特别适用于航空运输。下面结合实施例参照附图进行详细说明，以便对本发明的技术特征及优点进行更深入的诠释。
本发明的整体结构示意图如图 1-2 所示，一种可降解承重卡板，包括上盖 1、填充料中层 2 及下盖 3，所述下盖 3 的底部设置若干个卡板支撑脚 4，所述下盖 3 与若干个卡板支撑脚 4 一体成型，填充料中层 2 填充设置于下盖 3 及若干个卡板支撑脚 4 的内部，上盖 1 盖合于填充料中层 2 及下盖 3 上方，所述卡板支撑脚 4 的剖面设置为倒梯形。传统的结构的卡板，一般卡板支撑脚和卡板主体是分离的，分开加工，然后再组合使用。但是在航空运输中，容易造成多次使用折断或断裂的情况，本实用新型所述的下盖 3与若干个卡板支撑脚 4 一体成型，填充料中层 2 填充设置于下盖 3及若干个卡板支撑脚4 的内部，使支撑脚和主体一体填充成型，避免了断裂的情况，且一体成型的结构增加稳固性及承重强度，避免因较大外力造成突然出现断裂或者松动的情况。
本发明所述卡板支撑脚 4 的剖面设置为倒梯形，靠近下盖 3 底部一端的长度大于远离下盖 3 底部另一端的长度，所述倒梯形的倾斜角设置为30-60 度。本发明与其他现有技术不同的是，设置倒梯形的倾斜角设置为30-60 度，从工程力学的角度来讲，能够实现较轻的重量，承载较重的物品，例如，设置角度为 30 度、45 度或 60 度，不同的角度承载物体的强度有所不同，根据材料和需要设置角度。
如图 2、3 所示，本发明所述下盖 3 的底部设至少三排卡板支撑脚 4，每排至少设置三个卡板支撑脚 4，所述卡板支撑脚 4 底端中部设置下沉凹槽 41，每排的卡板支撑脚 4 之间一连接板 5，连接板 5 卡装于下沉凹槽 41内。卡装连接板 5 两端的下沉凹槽41 设置止回部，即仅设置一半下沉凹槽，另一半设置与底部平齐，这样使得连接板 5 能够更稳固的卡接于下沉凹槽 41 内，连接各个卡板支撑脚 4，增加承重能力。在卡板使用过程中，承重时容易造成物品与卡板之间的滑动，本发明所述连接板 5 的外表面设置防滑波浪纹。本实用新型中，卡板可以使用连接板 5，也可以不用连接板 5 单独使用。
目前，随着航空运输的发展，卡板的需求量越来越大，而随着卡板的新旧交替，旧的卡板必然需要回收和降解，才能不造成环境污染，而本发明所述上盖 1 及下盖 3 采用PET 材料（聚对苯二甲酸乙二醇酯）制成。上盖 1 和下盖 3 采用 PET 材料，对回收的卡板进行掩埋，自动降解。本发明所述上盖 1 及下盖 3 的外表面分布设置防滑波浪纹，增加卡板与物品之间的摩擦力。填充料中层 2 也可以采用 PET 材料完成自动降解，当然本实用新型并不限于 PET 材料，也可以采用 PVC 材料。
如图 4 所示，本实用新型所述上盖 1 与填充料中层 2 之间还设置一 IC芯片6，上盖 1 上设置一显示窗，IC 芯片6嵌装于显示窗内，所述 IC 芯片6为记忆芯片,具有记忆追踪功能。通过扫描 IC 芯片6，可以记忆追踪该卡板的位置，当然本实用新型所述的 IC芯片6 也可以设置于上盖 1 的侧面，通过扫描枪扫描获得物流信息，扫描枪获取到物流信息，从而与互联网相连，用户及时掌握卡板动态。为了使本发明所采用的材料完全自动降解，本发明所述填充料中层由以下质量份的组分制备而成，以下为几个实施例。
实施例 1

六氢三嗪催化剂 0.002 份；
C18 季铵盐催化剂 0.008 份；
DBU 季铵盐催化剂 0.00008 份；
硅油 0.016 份；
环戊烷 0.116 份；
PAPI 多亚甲基多苯基多异氰酸酯 1.3 份。
上 述 实 施 例 中 ， 聚 醚 多 元 醇 简 称 聚 醚 ， 是 主 链 含 有 醚 键（—R—O—R—），端基或侧基含有大于 2 个羟基（—OH）的低聚物，由起始剂（含活性氢基团的化合物）与环氧乙烷（EO）、环氧丙烷（PO）、环氧丁烷（BO）等在催化剂存在下经加聚反应制得。聚醚产量最大者为以甘油（丙三醇）作起始剂和环氧化物，通过改变 PO 和 EO 的加料方式（混合加或分开加）、加量比、加料次序等条件，生产出各种通用的聚醚多元醇。
聚醚多元醇 4110 的平均官能度为 4.0-5.0，羟值为 430-470mgKOH/g；聚醚多元醇 635 的平均官能度为 3.5-4.2，羟值为 470-490mgKOH/g；聚醚多元醇 380 的平均官能度为 3.4-3.8，羟值为 380-420mgKOH/g。例如，本实施例 1 中，聚醚多元醇 4110 的官能度为 4.0，羟值为 430mgKOH/g；聚醚多元醇 635 的官能度为 3.5，羟值为 470mgKOH/g；聚醚多元醇 380 的官能度为 3.4，羟值为 380mgKOH/g。
聚醚多元醇 4110 是用蔗糖、丙二醇、环氧丙烷合成，为蔗糖起始剂。聚醚多元醇635 为山梨醇起始剂。聚醚多元醇 635 及聚醚多元醇 4110 为硬泡聚醚，一般为聚氧化丙烯四醇或者六醇，以季戊四醇、乙二胺、糖、山梨醇等为起始剂，官能度较高，反应活性比软泡聚醚高很多。聚氨酯硬泡大量使用于家电保温、建筑外墙保温、大型冷库建设等，用量很大。这类聚醚生产相对简单，国内市场鱼龙混杂，市场价格比软泡聚醚稍低。软泡和硬泡聚醚的国内生产厂家相对集中，因其主要材料环氧丙烷和环氧乙烷的主要来自山东和进口货源。主要生产商：上海高桥石化、南京钟山石化、山东东大、山东德信联邦、天津三石化、抚顺佳化、中海壳牌、南京锦湖等。聚醚多元醇 380（聚醚多元醇 SA-380）为高活性聚醚，其反应活性高，例如河北廊坊生产的聚醚多元醇 380。本发明中所使用的聚醚多元醇 4110、聚醚多元醇 635 及聚醚多元醇 380 为溧阳化工厂提供的产品。
环戊烷用作溶剂、制取聚氨酯泡沫时的发泡剂（替代氟利昂） 及色谱分析标准物质等，环戊烷为纯品，浓度为 99.9-100%。PAPI 多亚甲基多苯基多异氰酸酯，或称粗 MDI，浅黄色至褐色粘稠液体．有刺激性气味，加入卡板制作中，改善卡板各组分的粘接性能。贮存于阴凉、通风、干燥的库房内，远离火种、热源。严格防水、防潮，避免光照。PAPI 相对密度(20℃/20 ℃)1．2，燃点 218℃。凝固点<10℃，黏度(25℃)200-1000mPa.s，例如，本实施例中，黏度(25℃)200mPa.s。PAPI 是由 50%MDI 与 50%官能度大于 2 以上的多异氰酸酯组成的混合物。由于 PAPI 的蒸气压较低，挥发度低，且成本低，所以以 PAPI 为原料，既环保健康，又降低了原料成本。
双胺醚溶液为 70%双(二甲基胺基乙基)醚溶液，由质量分数为 70%的双(二甲氨基乙基)醚与 30%一缩二丙二醇(DPG)配成的催化剂最常用。N,N-二甲基环己胺（氮氮二甲基环己胺）为无色至浅黄色透明液体，能溶于醇及醚类溶剂,主要用作聚氨酯硬泡催化剂。六氢三嗪催化剂为羟乙基六氢三嗪，形状为淡黄色透明粘稠状液体，含量 74.00～78.00%。C18 季铵盐催化剂为2,4,6-三(二甲氨基甲基)苯酚，也可以提供C18季铵盐的盐溶液，盐溶液的浓度为 60-80%。DBU 季铵盐催化剂为 1,8-二氮杂二环十一碳-7-烯，也可以提供 DBU季铵盐的盐溶液，盐溶液的浓度为 60-80%。双胺醚溶液、N,N-二甲基环己胺、六氢三嗪催化剂、C18 季铵盐催化剂、DBU 季铵盐催化剂为具有延迟作用的聚氨酯类催化剂，均为溧阳化工厂的产品，当以上催化剂提供盐溶液时，质量比为 60-80%。例如，在实施例中，以上的盐溶液浓度质量比可以为 60%。以上催化剂调节发泡和凝胶反应达到平衡，从而达到理想的发泡效果，使整个卡板具有较好的承压效果及透气效果。
硅油为环状聚二甲基硅氧烷，是由二甲基二氯硅烷加水水解制得初缩聚环体，环体经裂解、精馏制得低环体，然后把环体、封头剂、催化剂放在一起调聚就可得到各种不同聚合度的混合物，经减压蒸馏除去低沸物就可制得硅油。硅油的粘度为 100-200(25℃)cs，KS6840 硅油是表面活性剂，南京凯盛公司提供，例如，硅油粘度为 100(25℃)cs。
