知识共享:有机硅脱模剂生产及应用技术

发布日期:2018-11-05 作者: 点击:

橡胶塑料制品在模具中成型加工,橡塑材料与模具表面接触,可能因模具工作表面凹凸等微缺陷,使橡塑制品自模具剥离时会有一定的摩擦阻力。橡胶塑料在注射或挤出的加工过程中,橡塑材料和模具之间往往会形成负压,或二者之间因物理吸附或化学键合而致翰结,导致在橡塑制品成型后从模具中剥离困难。为了弱化制品与模具间的吸附或豁结,常常采用能够形成有效隔离膜的添加剂—脱模剂。脱模剂是一种用在两个彼此易于豁着的物体表面的一个界面膜层,使豁结物与被勃物之间形成隔离,从而易于剥离,使制品脱模更容易和更便捷。


1.脱模剂种类与应用概述


广义脱模剂包括许多种类型,分别应用于化工、冶金、建材等领域。本文局限于化工领域的脱模剂,主要讨论有关橡胶塑料等材料成型加工的外

可用做贵阳脱模剂的基础物质有很多种,常用的脱模剂有无机物、有机物和聚合物等类型。常用的无机物类脱模剂有石墨粉、滑石粉、云母粉、二硫化钥等粉体;常用的有机物类脱模剂有脂肪酸、脂肪酸皂、各种蜡类、乙二醇等,这类脱模剂兼有润滑剂的作用;聚合物类脱模剂主要有聚乙烯醇、醋酸纤维素、有机氟聚合物和有机硅聚合物等,其中有机硅聚合物是最适宜的脱模剂。

    贵州脱模剂中的溶剂组分主要是用于溶解主体有机硅聚合物,使之成为便于涂施的操作溶液。良好的溶剂要求其极性、溶解度参数与主体聚合物匹配。有的溶剂自身还兼具清洗作用,协同脱模剂溶液在模具工作面均匀展布和附着。在有的脱模剂中应用复合溶剂,其中各组分的极性和沸点有所差异,利用挥发梯度,避免单一低沸点溶剂快速汽化吸热、使局部达到露点导致脱模剂涂膜泛白起皱等缺陷。    气雾型有机硅脱模剂通常采用氟氯烷作抛射剂,如三氯一氟甲烷(Fll )、二氯二氟甲烷(F12)、二氯四氟乙烷(F114)等。由于氟氯烷具有较强的臭氧层破坏作用而面临淘汰,丙烷、异丁烷、正丁烷等逐步取代氟氯烷,成为通用的抛射剂。抛射剂的沸点和蒸气压对脱模剂的特性起着明显的作用,有时单一的抛射剂不能适应要求,往往采用混合抛射剂。    一般应用表面活性剂作脱模剂的润湿剂。润湿剂的作用是促进脱模剂在模具表面均匀展布,保证首次涂覆脱模剂和后续复涂脱模剂都能均匀流平。
