Description

一种塑料建筑模板用脱模剂及其制备方法
技术领域
本发明涉及建筑模板领域，具体涉及一种塑料建筑模板用脱模剂及其制备方法。
背景技术
混凝土成型需借助建筑模板来固定，待混凝土形成一定强度后需要拆除模板。为了防止模板拆除过程中混凝土粘连在模板上，给模板的再使用增加处理难度，通常会在模板内壁喷涂脱模剂。脱模剂在模板与混凝土表面之间起隔离与润滑作用，用以克服模板与混凝土表面的粘结力，使拆模时模板能顺利脱离混凝土，既保持混凝土形状完好无损，又保护模板表面不受损坏。但是现有的脱模剂容易造成塑料模板腐蚀，同时容易造成环境污染。
发明内容
为了克服现有技术不足，本发明提供一种塑料建筑模板用脱模剂及其制备方法，目的是使得模板可以顺利脱离混凝土，同时避免脱模剂对塑料建筑模板造成腐
蚀和可能造成的环境污染。

优选的所述的复配乳化剂是由乳化剂Span-80和OP-10复配得到，其重量比为1:2。
优选的所述的缓蚀剂是苯并三唑、磺化木质素、羟基乙叉二膦酸中的任意一种。
所述一种塑料建筑模板用脱模剂，其特征在于：由以下步骤制得：
步骤一：向硅油中加入聚丙烯蜡、聚丙烯醇、纳米氧化铝，充分混合后加热到105~110℃，保温12min，再自然冷却到50~55℃，然后继续加热至135~140℃，保温12min；
步骤二：向醋酸丁酯中加入正丁醇、锌粉、尿素，充分混合，加热到110~120℃，并自然冷却到50~55℃；
步骤三：将步骤二制得的物料加入到步骤一制得的物料中，并加入滑石粉、复配乳化剂、缓冲剂、蓖麻油、山梨醇酐油酸酯、聚丙烯酰胺，充分混合，加热到110~120℃，并自然冷却到50~55℃，制得脱模剂。
