Description
技术领域
本发明涉及高分子材料的回收领域,具体地,本发明涉及一种基于聚氨酯降解产物的木地板底漆。
背景技术
聚氨酯树脂制品形态有软质、半硬质及硬质泡沫塑料、弹性体、油漆涂料、胶黏剂、密封胶、合成革涂层树脂、弹性纤维等,广泛应用于汽车制造、冰箱制造、交通运输、土木建筑、鞋类、合成革、织物、机电、石油化工、矿山机械、航空、医疗、农业等许多领域,为保护资源和环境,现如今大力倡导各种塑料制品的回收利用,实现聚氨酯制品的循环利用将为节约资源、保护环境做出巨大贡献。
紫外光辐射固化技术是一种越来越成熟、应用越来越广泛的绿色环保技术,利用该技术生产的紫外光固化涂料,简称UV涂料。木地板底漆用UV底漆是装潢领域越来越盛行的方式。现有的UV涂料木地板用底漆需要采用大量的光固化单体,成本较高,使其应用受到限制。
因此,如何在保持UV涂料性能的同时降低成本,具有经济意义。
发明内容
本发明旨在克服上述现有技术的缺陷,提供聚氨酯降解产物在制备光固化木地板底漆中的应用,所述应用解决了聚氨酯废料的回收利用问题。
本发明的另一目的在于提供所述聚氨酯降解产物的制备方法。
本发明的另一目的在于提供基于聚氨酯降解产物的光固化木地板底漆,所制备的底漆硬度高,易打磨,附着力强。
本发明的另一目的在于提供所述光固化木地板底漆的制备方法。
本发明通过以下技术方案实现上述发明目的。
本发明公开了聚氨酯降解产物在制备光固化木地板底漆中的应用,所述聚氨酯降解产物为基于聚四氢呋喃醚(PTMEG)所制备的聚氨酯弹性体制品的边角料或废料醇解直接获得的降解产物,所述降解产物含有聚醚多元醇和二元胺,所述降解产物胺值为90~160。
本发明利用基于聚四氢呋喃醚所制备的聚氨酯弹性体制品的边角料或废料醇解直接获得的降解产物制备光固化木地板底漆,解决了聚氨酯废料的回收利用,且无需对降解产物分离提纯即可进行下一步操作,生产工艺相对简单,经济效益高,具有极高的推广价值。
优选地,所述聚醚多元醇占产物的70~85%。
所述聚四氢呋喃醚的数均分子量为1000~4000,这是用于制备聚氨酯弹性体制品常用的PTMEG类别。
所述聚氨酯降解产物通过如下方法制备得到:
S1.将聚氨酯弹性体制品边角料或废料、小分子二元醇、催化剂加入到反应釜中;
S2.加热,控制反应温度为180~230℃,反应时间1~3小时,出料,得到所述聚氨酯降解产物。
优选地,所述小分子二元醇为乙二醇、丙二醇、二乙二醇、丁二醇的一种或多种。
优选地,所述催化剂为醋酸钾、醋酸锌、异辛酸钾、乙醇胺、二乙醇胺、三乙醇胺或乙二胺。
一种光固化木地板底漆,包括以下按重量份计算的组分:
聚氨酯降解产物71~78份;
光固化单体9~14份;
光固化引发剂3~5份;
滑石粉9~10份。
本发明使用基于聚四氢呋喃醚所制备的聚氨酯弹性体制品的边角料或废料醇解后的产物作为主要原料,代替传统树脂,该聚氨酯降解产物中含有聚醚多元醇及大量二元胺类物质,胺类物质能够与光固化单体发生迈克尔加成反应,形成大量潜在的交联固化位点,后续加入的光引发剂,能促使光固化单体中大量未和胺基反应的残留的双键发生光固化,从而实现固化交联。特别地,当降解产物的胺值在90~160时,其最终固化交联获得的漆膜具有硬度高,易打磨,附着力强优点,具有良好的使用性能。同时,降解产物中的聚醚多元醇与光固化单体也具有良好的相容性。
优选地,所述光固化单体为官能度为2或以上的丙烯酸酯类活性稀释剂。
优选地,所述活性稀释剂为1,6-己二醇二丙烯酸酯、新戊二醇二丙烯酸酯、三丙二醇二丙烯酸酯、三羟甲基丙烷三丙烯酸酯、季戊四醇三丙烯酸酯中的一种或多种。
优选地,所述光固化引发剂为2-羟基-2-甲基-1-苯基-1-丙酮或1-羟基环己基苯基甲酮或两者的混合物。
所述光固化木地板底漆的制备方法,包括如下步骤:将聚氨酯降解产物和光固化单体于50~100℃混合均匀,再加入光引发剂及滑石粉。
与现有技术相比,本发明具有如下有益效果:本发明解决了基于聚四氢呋喃醚制备的聚氨酯弹性体制品边角料或废料的回收再利用问题,利于解决工业聚氨酯废料的环保问题;制备的底漆硬度高,易打磨,附着力强;生产工艺相对简单,经济效益高,具有极高的推广价值。

将71份由对比例2制备得到的聚氨酯降解产物和9份光固化单体于50℃混合均匀,再加入3份光引发剂1173及9份滑石粉。
对比例5
将71份线性高分子聚丙烯酸酯、9份光固化单体于50℃混合均匀,再加入3份光引发剂1173及9份滑石粉。
按实施例4~6、对比例3~5的方法配置底漆,将底漆涂覆于木地板上,过功率为2000W的紫外光固化机固化。考察底漆的附着力、硬度、耐打磨性。其测试结果见表1。
表1实施例木地板底漆性能测试结果
从对比例3和对比例4与实施例4的对比可知,聚氨酯弹性体制品边角料或废料的类别、降解产物胺值的大小都对木地板底漆附着力、硬度和打磨性有影响,只有利用基于分子量为1000~4000的聚四氢呋喃醚制备的聚氨酯弹性体制品边角料或废料,且降解产物胺值在90~160范围内,所制备的木板底漆才具有良好的综合性能。本发明用聚氨酯弹性体制品边角料或废料制备出的UV木地板底漆的附着力、硬度与聚丙烯酸酯相当,且成本大大降低。
