Description

一种纸质家具的制作方法
技术领域
本发明涉及造纸技术,特别是一种纸质家具的制作方法。
背景技术
纸质家具是材料以纸质为主的家具都可以统称纸家具。如瓦楞纸家具。纸家具常用的材质是瓦楞纸,与包装物流领域的纸箱在工艺上区别不大,表面就是牛皮纸,只不过选用了最好的材料,本身的承重力更强,而且通过结构设计可以实现更大承重。这些家具大多用的都是进口纸张,防水性很好,能够防水5分钟以上,因此很容易清洁,只需要用湿布擦洗就行。相比传统家具,纸家具的造价并不低,但是相对于有品牌、有设计的传统家具,一些普通纸家具的成本还是较低的,售价也低得多。但传统意义上的纸质家具还是存在一定的问题,如强度不高。
发明内容
本发明的主要目的在于提供一种整体结构强度较高、更为环保的纸质家具的制作方法。
为达到以上目的,本发明采用的技术方案为:一种纸质家具的制作方法,包括使用专用粘胶剂对瓦楞纸进行黏合,其中专用粘胶剂按重量份包括蒸馏水200-300份,淀粉50-70份,填料20-30份,氧化剂1-5份,氧化终止剂1-5份,亲水剂3-6份,琼脂粉5-10份,硬脂酸4-8份,糊化剂2-5份,催化剂5-10份,防腐剂0.5-1.5份,阻燃剂0.3-0.7份,氧化锌1-2份,pH调节剂按工艺pH值要求量;
所述瓦楞纸按照重量份包括在100份原浆中含有1-5份改性剂和1-3份增强剂,其中所述改性剂按重量份包括50-60份二氧化钛、10-15份珍珠岩、10-15份二硫化钼和1-5份稀土元素;所述增强剂按重量份包括40-50份的石墨烯、20-30份氮化硼、10-15份的蛭石、1-5份的重晶石粉、1-5份的硫化锑和1-5份的锆英石。
所述专用粘胶剂中的淀粉为玉米淀粉、马铃薯淀粉、木薯淀粉、小麦淀粉、大米淀粉中的一种或两种以上的混合物;所述填料为轻质碳酸钙、蒙脱土、膨润土和氧化铝粉的混合物,重量份数比为轻质碳酸钙:蒙脱土:膨润土:氧化铝粉等于2:3:2:1;所述氧化剂为过氧化氢和过硫酸钾的混合物,其重量份数比为1:1,所述氧化终止剂为硫代硫酸钠和亚硫酸钠的混合物,其重量份数比为2:1,所述亲水剂为二羟甲基丁酸;所述糊化剂为氢氧化钾或氢氧化钠中的一种或两种的混合物;所述催化剂为聚乙二醇;所述防腐剂为对羟基苯甲酸丙酯、脱氢乙酸钠、双乙酸钠、乳酸钠、苯甲酸钠中的一种或两种以上的混合物;所述阻燃剂为十溴二苯乙烷、红磷母粒、氢氧化铝、氢氧化镁、三聚氰胺中的一种或两种以上的混合物;所述pH调节剂为氢氧化钾或盐酸。
所述瓦楞纸的表面涂覆有施胶剂,其中施胶剂按重量份包括20-30份纳米丁腈橡胶、10-15份环氧树脂、5-10份的改性酚醛树脂、5-10份水凝胶、20-30份尿素和40-50份水。
一种纸质家具专用粘胶剂的制备方法,包括以下步骤:
(1)制备填料:将轻质碳酸钙:蒙脱土:膨润土:氧化铝粉按重量份数比为2:3:2:1均匀混合,过800-1000目筛,待用;
(2)制备氧化剂和氧化终止剂:将过氧化氢和过硫酸钾以重量份数比为1:1均匀混合,得到氧化剂待用;将硫代硫酸钠和亚硫酸钠以重量份数比为2:1均匀混合,得到氧化终止剂,待用;
(3)将50-70份淀粉放入反应釜A中,随后缓慢倒入100-150份蒸馏水,同时打开搅拌器,搅拌速度为80-120r/min,再2-5份加入糊化剂,搅拌20min,加入1-5份氧化剂后,再依次加入余量的淀粉和蒸馏水,在50-70℃下搅拌反应0.5-1h,随后加入1-5份氧化终止剂,在50-60℃下搅拌20-30min,待用;
(4)将20-30份填料、1-2份氧化锌、0.3-0.7份阻燃剂放入反应釜B中,混合均匀,再依次加入5-10份琼脂粉、4-8份硬脂酸和5-10份催化剂,在60-70℃下搅拌反应0.5-1h,得到混合物,待用;
(5)将步骤(4)所得到的混合物加入至反应釜A中,随后加入0.5-1.5份防腐剂、3-6份亲水剂,在70-80℃下搅拌5-10min,用pH调节剂将反应釜A中的pH值调节至6-7,搅拌反应0.5-1h后,即可得到纸质家具用粘胶剂。
由于在制备氧化淀粉时,原淀粉中葡萄糖单元上的羟甲基被氧化成羧基,使得胶黏剂的稳定性得到明显提高;其中采用的水位蒸馏水而非自来水;所用淀粉尽量取为成本相对较低的玉米淀粉和木薯淀粉,或者其他植物淀粉的混合物;其中填料采用的轻质碳酸钙、蒙脱土、膨润土和氧化铝粉的混合物,一方面,想降低成本,另一方面综合性能,提升填料的性价比。其中采用的有氧化剂和氧化终止剂,可控制氧化反应的进行程度,保证反应的完全和原料的物尽其用,亲水剂让反应更好地均匀进行,而琼脂粉和硬脂酸能提升粘胶剂的粘合性,催化剂的引入可促进反应的进行,其中催化剂为聚乙二醇,环保无毒低成本。
此外,纸质家具多少存在火灾隐患,所以本发明人在反应物中添加了阻燃剂,既不影响粘胶剂的性能,又可防患于未然,同时,在其中加入了一定量的防腐剂。在其中加入的氧化锌可提高粘合剂的强度和拉伸性。其中,pH调节剂为氢氧化钾或盐酸,根据反应进行中的混合物当时所处pH值来选择,若偏碱性用盐酸调节至pH值为6-7,若偏酸性,反之。
一种纸质家具用瓦楞纸的制备方法,包括以下步骤:
步骤一、选取造纸原料,加水进行泡浆,投入碎浆机中粉碎,使造纸原料离解为纸浆;
步骤二、所述纸浆依次经过压力筛和除渣器除去杂质;
步骤三、经除杂后的纸浆输入至磨盘进行打浆处理,制得原浆;
步骤四、往以重量计的100份原浆中加入1-5份改性剂和1-3份增强剂,充分搅拌,而后去除水分,得到含水率为10-20%的抄纸浆,
步骤五、将抄纸浆送至网部成型脱水至干度为15-25%;
步骤六、成型后的浆料输送至压榨部,压榨部将所述浆料压榨脱水至干度为40-50%,然后采用施胶机将施胶剂均匀涂抹在纸张表面;
步骤七、将表面施过胶的瓦楞纸半成品放入烘缸内,调至温度到105-110℃,水份在2-4%,放在室内静置24小时以后,再取出放在通风干燥处放置24小时,即可得到高强度的纸质家具用瓦楞纸。
所述造纸原料按重量份包括木屑70-80份和废纸20-30份。
所述改性剂的制备方法是将50-60份二氧化钛、10-15份珍珠岩、10-15份二硫化钼和1-5份稀土元素混合均匀,然后边搅拌边加热,加热温度是200-250℃,待冷却后研磨成粉末即得改性剂。
所述增强剂的制备方法是先将40-50份的石墨烯、20-30份氮化硼、10-15份的蛭石和1-5份的锆英石混合均匀,然后放入反应釜中,加热温度为600-700℃,加热时间30min,待冷却至200℃后再加1-5份的重晶石粉、1-5份的硫化锑,加热时间15min,冷却后研磨成粉末即得增强剂。
所述施胶剂的制备方法是将20-30份纳米丁腈橡胶、10-15份环氧树脂、5-10份的改性酚醛树脂、5-10份水凝胶、20-30份尿素和40-50份水,搅拌均匀后加热至50-60℃使各成分全部溶解,待温度自然降低至室温即可。
所述改性剂中的二氧化钛作为粘结剂,可以提高各个原料之间的粘结强度,珍珠岩可做保温材料,提高耐热性,二硫化钼作为润滑剂,稀土元素促进上述有效成分的功效发挥,最终提高瓦楞纸的强度。
所述增强剂中的石墨烯和锆英石,大大增强了瓦楞纸的耐破指数和环压指数,使得本瓦楞纸具备较高的强度,提高了瓦楞纸箱的使用寿命。氮化硼和蛭石可以提高瓦楞纸的物理强度,提高纸板整体的紧实感以及表面性质,提高纸张紧度及横向环压指数,同时增强其尺寸稳定性。重晶石粉、硫化锑作为助剂,可以提高其他成分的联结,促进增强剂发挥更好的作用。采用本发明的生产方法制得的瓦楞纸的各项性能和物质指标完全符合瓦楞纸的各项要求。
所述施胶剂中的纳米丁腈橡胶、环氧树脂、改性酚醛树脂,能大幅度提高表面施胶的效果,增强瓦楞纸环压强度。另外将水凝胶加入瓦楞纸表面施胶剂基料中,能够改善施胶剂施胶后纸张的疏水性,同时还可以改善各种构成相之间的表面张力,使之形成均匀稳定的分散体系。
所述造纸原料包括木屑和废纸,有效的利用各行业所产生的废弃物,适应全社会倡导的节能环保以及循环经济精神。
本发明得到的一种纸质家具的制作方法,其技术效果通过自主研发的专用胶黏剂和高强度瓦楞纸,从而大大增强了纸质家具的耐破指数和环压指数,使得纸质家具具备较高的强度,提高了纸质家具的使用寿命。
