Description
技术领域
本发明涉及硬木家具加工技术领域,特别涉及一种硬木家具用改性聚丙烯蜡烫蜡方法。
背景技术
硬木家具因其天然的独特的纹理被广泛应用,在硬木家具表面进行烫蜡是一种较为环保的表面处理方法,凸显木材表面纹理,带给人舒适的视觉感受,越来越受到人们的喜爱。随着资源的减少,红木类名贵木材资源匮乏,榆木、榉木、水曲柳等硬木逐渐占有市场,较为环保的硬木表面处理方法也备受关注。传统的烫蜡工艺中使用的蜡多为蜂蜡和虫蜡,凸显木材表面纹理,具有美观性和保护作用。但是天然蜡与木材几乎无化学结合,且熔点较低,受热容易熔化,破坏木材美观性。
发明内容
本发明要解决的技术问题是提供一种硬木家具用改性聚丙烯蜡烫蜡方法,解决了传统烫蜡耐热性差和烫蜡表面结合弱的问题,从一定程度上提高蜡与木材的结合力,增强了烫蜡家具的耐热性和耐磨性,扩宽了烫蜡家具的应用范围。
为了解决上述技术问题,本发明提供的技术方案为:
一种硬木家具用改性聚丙烯蜡烫蜡方法,包括以下步骤:
(1)将硬木家具木材在碱性溶液中浸泡30min~60min,进行木材预处理,捞出后气干处理2~3天,直至质量恒重;
(2)依次用180目、240目砂纸对硬木家具表面进行粗磨处理,去除戗茬、起毛等缺陷,用热棉布轻轻地擦拭家具表面,除去木渣、粉尘等杂物;
(3)用400目水砂纸顺着纹理方向,对硬木家具表面进行水磨处理;
(4)取适量的改性聚丙烯蜡加热使之熔化,用蜡量为50~100g/m2;
(5)采用电热风枪烘烤木材试样表面,用刷子蘸取液态改性聚丙烯蜡点涂到木材表面,继续用电热风枪加热,使蜡均匀布满木材表面;
(6)采用电弓加热器对木材表面从室温升温到预定温度烘烤,预定烘烤温度为160~260℃,烘烤时间为1min~3min,用绑在小木块上的干净白布不断擦拭烫蜡用硬木表面,使改性聚丙烯蜡蜡完全浸入到木材管孔中;
(7)自然降温一定时间后,待蜡在家具表面凝固,用蜡起子铲去表面浮蜡,起蜡时间在5~10min,并用白布揩擦抛光,再用低温烘烤数秒,以清除铲痕,烫蜡完成。
进一步地,所述步骤(1)中碱性溶液为NaOH溶液,NaOH质量分数为4%~9%,去除木材抽提物,使导管通畅,同时增强木材极性,与蜡产生结合。
进一步地,所述步骤(4)中的改性聚丙烯蜡为马来酸酐接枝改性聚丙烯蜡,包括如下重量百分含量的各组分:二甲苯溶剂60~80份,聚丙烯蜡15~30份,马来酸酐4~8份,引发剂0.6~1.2份。制备步骤为:四口瓶中加入15~30份聚乙烯蜡和60~80份二甲苯,接通氮气,在油浴锅中加热至聚丙烯蜡溶解,升温至预定温度90~120℃,搅拌速度为300~500r/min,充分搅拌;马来酸酐和过氧化苯甲酰溶于少量二甲苯溶剂中,分三次滴加到四口瓶中;反应时间为1~5h,反应到达预定时间后,采用丙酮抽滤3次;将接枝产物放入真空干燥箱中恒温干燥直至接枝产物质量恒重,得到改性聚丙烯蜡。
与现有技术相比,本发明具有如下的有益效果:
本发明所述的硬木家具用改性聚丙烯蜡烫蜡方法,使得烫蜡后的硬木家具表面纹理清晰,耐磨性增强,耐热性提高,且改性聚丙烯蜡具有一定的极性,可与处理后木材产生氢键结合,结合力增强,较为明显的提高了硬木家具性能。
