隔热、 保温、 防烫纸制或塑料制容器的制备方法及其产品 技术领域
本发明涉及纸制或塑料制容器的制备方法， 尤其涉及一种隔热、 保温、 防烫 并具有彩色立体花紋的纸制或塑料制容器的制备方法以及由该方法制备得到的产 品， 属于日常生活用品领域。 ' 背景技术
一般容器， 其在成本与用途之普遍化上， 大都以纸制或塑料制容器为大宗， 例如： 纸制或塑料制之杯、 碗、 盘， 或以该材质制成之装添容器， 例如： 包装容 器、 保温容器、 便当盒等。
现有的纸制容器仅为单层， 无法提供保温、 隔热效果， 若以双层折迭或间隔 一隔间， 则使用一次即丢之用途上， 其成本极高， 实不符成本效益。 塑料容器仅 为单层， 更无保温、 隔热效果。 另外， 现有的纸制或塑料制容器之表层， 为达美 观性， 顶多仅在表层上印刷， 并无法达成立体花紋之效果。
目前使用之纸杯， 为了防烫， 则需另以塑料托杯作为承托该纸杯之用， 其当 可防止纸杯握持之防烫效果， 但使用上必须增加该托杯之不便， 且使用后， 该纸 杯在丢弃后托杯还需收藏， 则有消弱该纸杯使用之方便性原意。
若以发泡方式在该纸制容器或半成品纸制品***发泡， 如美国专利第
5952068号， 其系使用压克力胶 （Acrylic) ， 而另一美国专利第 6265040号， 其 发泡特性系在 65至 100°C发泡。前述所使用之压克力胶，其为高玻璃转化点者时， 容易在低温下发泡率不足， 而在高温时发生容器变形， 该纸杯内之淋膜层（PE或 PP) 损坏。 若采用低玻璃转化点者之压克力胶， 则在常温下容易发生黏性， 如半 成品采重迭方式备料储置,待需要时再加温发泡方式时将会发生困难， 使库存无法 掌握； 若使用受热在一定温度下迅速软化之压克力胶之基材， 一般系应用在芯片 切割或电子零件生产制程上， 其价格昂贵， 实不符使用于价格低廉之用后即丢之 纸制品上。
按前述所称以 65至 100°C可发泡之发泡基材，如可在纸制品上达到完全发泡， 其所需发泡时间将非常长， 此时间将令纸制容器变形、 损坏、 及回湿等问题， 且 生产效率甚低。 发明内容
本发明所要解决的技术问题是克服现有技术的不足， 提供一种新的纸制或塑 料制容器的制备方法， 由该方法制备得到的纸制或塑料制容器具有隔热、 保温、 防烫等效果， 该的容器外表面上还可具有彩色立体花紋， 与普通纸制或塑料制容 器相比， 其外型更为美观。
本发明所要解决的技术问题是通过以下技术方案来实现的：
一种隔热、 保温、 防烫纸制或塑料制容器的制备方法， 包括以下步骤：
1、 液态接着剂与热发泡粒子粉搅拌混合， 得复合涂料；
2、将复合涂料涂布于连续纸匹或塑料所设定范围内或已成型之各种纸制或塑 料容器之表面所设定范围 （说明： 为了达到隔热、 保温、 防烫的效果， 只需将该 复合涂料涂布于成型容器之任何可供握持之位置与范围， 而不需全面涂布， 这种 可供握持之位置与范围即为所述的"设定范围"， 这一点， 本领域普通技术人员可 视具体情况并根据实践经验来掌控） 内， 再将该纸匹、 塑料或成型容器进行加热
(加热的温度最好为 100至 140°C ) ， 使该表面藉该发泡粒子产生发泡作用 （发 泡程度可以达到 20-50倍体积） ， 同时该液态接着剂黏附于该容器之表层， 使纸 匹、 塑料或成型容器的表层形成黏附在其上的发泡层， 再将连续纸匹或塑料按照 现有技术制成所需要的成型容器。
上述制备方法中， 所述的液态接着剂可以为水性的聚醋酸乙烯酯树脂或聚乙' 烯 -聚醋酸乙烯酯树脂或以上两者按任意比例混合后所得到的混合液， 同样能在加 热发泡过程中， 具有凝固接着作用。 所述的液态接着剂均可直接从市场购得。
所述的热发泡粒子粉为热塑性聚合物内包覆低沸点溶剂， 可于最短时间完成 发泡而不伤及纸制品， 所述的热发泡粒子粉可直接从市场购得。
优选的， 将液态接着剂与热发泡粒子粉按照 5-20: 80-95的重量比例混合而 成。
为了使所制备的纸制或塑料制容器的外型更为美观， 本发明还可以在复合涂 料中添加彩色颜料 （至于添加何种颜色以及该彩色颜料与复合涂料的配比比例， 本领域的技术人员可视具体情况或实际需要而完全可以掌控）后喷涂或轮转辊压， 使喷涂在有花紋部份之前述涂料， 经加热后产生发泡作用， 以形成突出之彩色立 体花紋， 或在形成立体花紋后再彩色印刷， 以呈现多样化之美观视觉效果， 同时 在该突出之立体花纹上， 即可提供握持之隔热功能， 达到美观性、 保温、 隔热、 防烫之多重效益者。
本发明可在各种纸制容器表面上， 依图案模型形成各种立体花紋， 达到美观 性及提供握持该突出花紋之防烫效果者。
前述立体花紋之突出程度， 可依涂布该复合涂料之厚度， 藉加热温度控制在 100至 140°C范围， 以获得所需花纹突出程度之需求者， 且可在短时间完成发泡， 以克服发泡时间过长之问题。
本发明制备方法亦可将容器成型时同时将容器外表层的设定区域 （说明： 为 了达到隔热、 保温、 防烫的效果， 只需将该复合涂料涂布于成型容器之任何可供 握持之位置与范围， 而不需全面涂布， 这种可供握持之位置与范围即为所述的"设 定范围"， 这一点， 本领域普通技术人员可视具体情况而定） 凹陷 （如图 4-C) 依 适当范围， 再将复合涂料涂布于该凹陷位置， 使复合涂料经加热发泡后将该凹陷 位置予以填平， 使容器外表层恢复平整状态， 即可提供握持位置之防烫效果， 以 降低成本。
本发明将液态接着剂与发泡粒子粉配比在一起后，通过制程之加热发泡过程， 藉该材料特性， 达到快速发泡与不会损及纸制容器及其内膜， 且透过该容器表层: 之发泡层具有补强效果， 使盛装较高温物质时， 提供握持者不会产生热烫感， 以 提供保温、 隔热、 防烫保温效果。
本发明方法可适用制备各种纸制或塑料制容器， 如杯、 碗、 盘、 便当盒及各 种包装容器等， 均可达到隔热、 保温、 防烫及补强效果。 附图说明
