Description

一种塑料表面的处理工艺
技术领域
本发明属于塑料加工技术领域,尤其涉及一种塑料表面的处理工艺。
背景技术
塑料是以单体为原料,通过加聚或缩聚反应聚合而成的高分子化合物,俗称塑料或树脂,可以自由改变成分及形体样式,由合成树脂及填料、增塑剂、稳定剂、润滑剂、色料等添加剂组成。
塑料的主要成分是树脂。树脂这一名词最初是由动植物分泌出的脂质而得名,如松香、虫胶等,树脂是指尚未和各种添加剂混合的高分子化合物。树脂约占塑料总重量的40%~100%。塑料的基本性能主要决定于树脂的本性,但添加剂也起着重要作用。有些塑料基本上是由合成树脂所组成,不含或少含添加剂,如有机玻璃、聚苯乙烯等。大多数塑料质轻,化学性稳定,不会锈蚀;耐冲击性好;具有较好的透明性和耐磨耗性;绝缘性好,导热性低;一般成型性、着色性好,加工成本低,塑料给人们生活带来巨大便利;但塑料在使用过程中会出现韧性下降,容易折损,如空调机箱外壳、油烟机的外壳等等,在使用一段时间后需要对其更换,因其韧性低,损坏几率大,这样使用增加了投入成本,而且更换过程复杂,操作不便。
发明内容
本发明的目的在于提供一种塑料表面的处理工艺,以改善塑料的韧性,延长其使用寿命,降低投入成本。
为实现上述目的,本发明提供如下技术方案:一种塑料表面的处理工艺,包括如下步骤:
1)、打磨,用砂纸对塑料表面进行打磨处理;
2)、清洁,将塑料浸在工业酒精中进行去油污处理;
3)、水洗,将塑料经由流水的冲刷,进行表面的清洁;
4)、烘干,在40-50℃的温度下,干燥10-20min,去除水分;
5)、涂料,涂料其组分按其重量配比如下:聚氨酸丙烯酸5-10份、聚丙烯酸钠3-8份、酚醛树脂1.8-3.5份、醋丙乳液0.8-2.3份、己二醇丁醚醋酸钠0.2-0.6份,将涂料均匀的涂布在塑料的表面上。
6)烘干、将涂料之后的塑料在50-60℃的环境下,干燥10-20min;
7)成品、将干燥之后的塑料包装、库存。
优选的,所述步骤2)中可有次氯酸钠溶液代替工业酒精对塑料表面的油污进行处理。
优选的,所述步骤5)的涂料过程中可在其中加入不同颜色的颜料,使之与涂料混合均匀,涂布在塑料表面,以增强塑料整体的美观性,使之有更好的审美效果。
优选的,所述步骤5)中可加入硅藻土份5-7份,以增强涂料的吸附效果,使涂料与塑料集体结合更加牢固。
优选的,所述步骤5)中的涂料中可加入苯酐1-3份、顺酐0.5-2份,以改善涂料的整体柔韧性,使之更容易涂布在塑料基体至上。
本发明的有益效果:本发明通过在塑料基体表面涂布一层致密的涂层,改善了塑料基本本身的韧性,延长其使用时间,同时可改变涂料本身的颜色,以搭配出不同风格,不同品味的外观,更加迎合市场的需要;并且改变涂料本身的柔韧性,使之更容易贴合,不易剥落,延长塑料的使用寿命,使之不易损坏,更加符合大众的需求。
