Description
本发明涉及餐具制备技术领域，具体是一种高强度纸浆模塑餐具及其制备工艺方法。
餐具有金属器具、陶瓷餐具、茶具酒器、玻璃器皿、纸制器具、塑料器具以及五花八门、用途各异的各种容器类工具(如碗、碟、杯、壶等)和手持用具(如筷、刀、叉、勺、吸管、签棒等)及等用具。市场上还出现了许多一次性的餐具，这种餐具对环境不好，也有一些可降解材料制作的餐具。
纸浆模塑餐具是指用模具对纸浆经真空吸附成型、烘干，再经深加工制成的可以代替金属，塑料来供人们所使用的餐具。由于其具有保护生态环境和资源再次利用的优点，因此应大力开发使用绿色包装材料，大力发展纸浆模塑制品和餐具系列是21世纪大趋势。
目前市售的纸浆模塑餐具虽然较为绿色环保，但是其本身的强度性能相对较差，特别是刀、叉、勺使用时产生软化影响使用，具体为刀餐具端面硬度不足以顺利切割牛排肉类、叉餐具无法顺利刺穿食材以供食用。再者，现有的纸浆模塑餐具的制备工艺多数为定型与切边多个步骤进行的方式进行，使得生产流程增加，增加了生产设备数量及成本。因此，本发明提供了一种高强度纸浆纸浆模塑餐具及其制备工艺，以解决上述问题。
本发明要解决的技术问题是针对上述现有技术的不足，提供一种高强度的纸浆模塑餐具，采用甘蔗浆纸和竹浆纸为主体原料，并以特定的制备工艺方法，使得压制成型的餐具整体结构强度高，在具有环保效果的前提下，能够防渗漏和耐高温，结构稳定。
为实现上述目的，本发明提供纸浆模塑餐具的技术方案为：一种高强度纸浆模塑餐具及其制备工艺方法，按质量百分比由以下材料制成：原料浆纸92.5-95份、防油剂1-1.5份、防水剂4-6份，所述原料浆纸包括甘蔗浆纸和竹浆纸，其中甘蔗浆纸62.5-95份、竹浆纸0-30份，其中甘蔗浆纸和竹浆纸均是纤维强度较好的原料，并且是成型纸产品，对于增强纸浆餐具的结构强度具有极大的基础提升。
作为进一步的方案：所述原料浆纸包括新料浆纸和切边料纸，其中新料浆板和切边料板的质量比为（24-26）:3，因在生产制备过程中，随着产品的产生，切边剩余的切边料纸并未得到有效利用，而其并未经过污染，可填充部分回料至新料浆纸中，降低整体的生产成本。
作为进一步的方案：所述防水剂选用CZ-201 阳离子中性施胶剂，主要成分设为丙烯酸丁酯，浓度为23±0.5%。
作为进一步的方案：所述防油剂选用AG-E860纸浆专用防油剂。
另外，本发明还提供了纸浆模塑餐具制备工艺方法的技术方案为：一种高强度纸浆模塑餐具的制备工艺方法，包括以下步骤:
S1、泡浆碎浆，将原料浆纸按需称量好作为原料放入等重量的水中静置时间15-20min，使其充分吸水软化，然后将软化的纸板置入碎浆机桶内，调节碎浆机桶内碎浆机的粉碎转速设置为300-600r/min，运行时间8-10分钟，将软化的纸板彻底打碎，备用；
S2、配浆供浆，将经上一步骤粉碎的浆板转移放入配浆池中，并向配浆池中按清水与原料称重重量以6:1再加入对应清水，并进行充分搅拌形成配浆，然后以先加防油剂后加防水剂的顺序加入配浆池，提供定量的防油防水剂，并对防油防水剂进行充分搅拌；将配浆池中的浆液放入供浆池中，并设定配浆池内搅拌转速设置为100-150r/min进行搅拌，得到混合浆液，然后通过输送管道送到车间；
S3、调浆捞浆，预先通过调整定量杯来控制浆液的体积，从而确定产品的克重参数，成型机捞浆桶升起，并把网布放入捞浆模中，然后放下捞浆模，按下供浆按钮，将上一步骤的浆液送入到成型机的冷模内，供浆结束后，按抽真空按钮将混合浆液中的水分以真空过滤方法滤去70-80%，其中克重设置为，真空度设置为0 .04～0 .08Mpa，捞浆时间设为20～50s，得到毛坯纸板，取出备用；
S4、定型切边，将毛坯纸板转移至成型机的热模内，热模的加热盘对毛坯纸板进行加热和挤压，其中热板温度165±25℃，油缸压力在50～100t，定型时间40～80s，定型完成后，由热模直接冲裁毛坯纸板完成切边落料作业，即可得到产品和余留的切边料纸；
S5、检验消毒，将切边下来的产品分散不重叠地放置于消毒传送带上，开启传送带电机，并设置紫外线消毒灯及吹风机启动，同时检查产品外观是否合格；然后将经过消毒后的产品放入中转箱中，再通过检针机检查产品中是否含有铁丝金属，满足要求后对产品进行包装。
作为进一步的方案：所述定型热模中设置餐具成型形状设置成刀、叉、勺中的任一种。
作为进一步的方案：所述S3步骤中供浆后余下的浆水回浆至供浆池。
作为进一步的方案：所述S3步骤中还设置回水池，在捞浆后真空过滤的水分接入回水池，所述回水池与配浆池连通供给补水。
与现有技术相比，本发明的有益效果是：1、添加的原料浆纸中主体是甘蔗浆纸，并可以按需添加竹浆纸，因该两种浆纸的纤维相比于木浆纸更粗更硬，并且成本更低且都是成型纸产品，减少了加工的工序，在配置中还可将生产过程中的余下的切边料板和新料混合进行生产，有效降低成本，并且防水剂和防油剂的添加能有效增强整体餐具的防水防油性能。
2、制备工艺方法的S1步骤中增加了低水泡浆及碎浆流程，相比于现有技术中直接全量水泡浆碎浆的方式，减少了在碎浆过程中为带动大量水而对碎浆机作用效率的影响，使得整体碎浆效果更细更佳，便于后续流程的更好实现，并且将热压定型和切边步骤合并进行，节省了工艺流程及成本，降低了两次挤压过程中对于操作人员身体伤害风险，并设定了更合适热板温度、油缸压力及定型时间，使得压制成型的餐具更紧密，从而起到固化的效果，从而提升产品的结构强度和防渗漏、耐高温效果。
下面将结合本发明实施例中，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。

本发明所提供的的一种纸浆模塑餐具及其制备工艺方法，按质量百分比由以下材料制成：原料浆纸93份、防油剂1份、防水剂6份，其中原料浆纸中均为甘蔗浆纸，该甘蔗浆纸为甘蔗榨汁后的废品纤维制成，为成型纸产品，在实际制备时，其中的原料浆纸包括新料的甘蔗浆纸和上个生产工艺切边留下的切边料纸进行组合，其中新料浆板和切边料板的质量比为26:3，其中防水剂选用CZ-201 阳离子中性施胶剂，主要成分设为丙烯酸丁酯，浓度为23±0.5%所述防油剂选用AG-E860纸浆专用防油剂，通过制备工艺制成刀、叉、勺形态的纸浆模塑餐具。
为了制备上述纸浆模塑餐具，本实施例采用了一种高强度纸浆模塑餐具的制备工艺方法，其中具体以制备刀形态的餐具为例，具体包括以下步骤:
S1、泡浆碎浆，将原料浆纸称量好甘蔗浆纸的新料浆板52kg、切边料板8kg，检查作为原料放入等重量的水中静置时间15-20min，使其充分吸水软化，然后将软化的纸板置入碎浆机桶内，调节碎浆机桶内碎浆机的粉碎转速设置为600r/min，运行时间8分钟，将软化的纸板彻底打碎，呈现碎浆机桶内的浆水呈细泡沫白浆以备用；
S2、配浆供浆，将经上一步骤粉碎的浆板转移放入配浆池中，并向配浆池中按清水与原料称重重量以6:1再加入对应清水，并进行充分搅拌形成配浆，然后以先加防油剂后加防水剂的顺序加入配浆池，提供定量的防油防水剂，并对防油防水剂进行充分搅拌，具体为在加入对应试剂之后分别进行搅拌5分钟；将配浆池中的浆液放入供浆池中，并设定配浆池内搅拌转速设置为150r/min进行搅拌，得到混合浆液，然后通过输送管道送到车间成型机备用；

为了制备上述纸浆模塑餐具，本实施例采用了一种高强度纸浆模塑餐具的制备工艺方法，其中具体以制备勺形态的餐具为例，具体包括以下步骤:
S1、泡浆碎浆，将原料浆纸称量好甘蔗浆纸34.5kg、竹浆纸17.5kg，同样比例搭配的甘蔗浆纸62份、竹浆纸31份制备的切边料板8kg，检查作为原料放入等重量的水中静置时间15-20min，使其充分吸水软化，然后将软化的纸板置入碎浆机桶内，调节碎浆机桶内碎浆机的粉碎转速设置为00r/min，运行时间10分钟，将软化的纸板彻底打碎，呈现碎浆机桶内的浆水呈细泡沫白浆以备用；
S2、配浆供浆，将经上一步骤粉碎的浆板转移放入配浆池中，并向配浆池中按清水与原料称重重量以6:1再加入对应清水，并进行充分搅拌形成配浆，然后以先加防油剂后加防水剂的顺序加入配浆池，提供定量的防油防水剂，并对防油防水剂进行充分搅拌，具体为在加入对应试剂之后分别进行搅拌5分钟；将配浆池中的浆液放入供浆池中，并设定配浆池内搅拌转速设置为150r/min进行搅拌，得到混合浆液，然后通过输送管道送到车间成型机备用；
S3、调浆捞浆，预先通过调整定量杯来控制浆液的体积，从而确定产品的克重参数，具体为根据制备产品的要求进行设定；其中捞浆具体设置为成型机捞浆桶升起，并把网布放入捞浆模中，然后放下捞浆模，按下供浆按钮，将上一步骤的浆液送入到成型机的冷模内，供浆结束后，按抽真空按钮将混合浆液中的水分以真空过滤方法滤去70-80%，其中真空度设置为0.04Mpa，捞浆时间设为50s，得到毛坯纸板，取出备用；其中供浆后余下的浆水回浆至供浆池以备下次供浆使用，另外设置回水池，在捞浆后真空过滤的水分接入回水池，所述回水池与配浆池连通供给补水；
S4、定型切边，将毛坯纸板转移至成型机的热模内，热模的加热盘对毛坯纸板进行加热和挤压，其中热板温度165±25℃，油缸压力在50t，定型时间40s，定型完成后，由热模直接冲裁毛坯纸板完成切边落料作业，即可得到产品和余留的切边料纸；
S5、检验消毒，将切边下来的产品分散不重叠地放置于消毒传送带上，开启传送带电机，并设置紫外线消毒灯及吹风机启动，同时检查产品外观是否合格；然后将经过消毒后的产品放入中转箱中，再通过检针机检查产品中是否含有铁丝金属，满足要求后对产品进行包装。
其中勺子因不需较高硬度要求，对于其制备的条件相较于制作刀餐具的要求稍低，如定型步骤中油缸压力及定型时间均可适当调低。
