Description

生物柴油混凝土脱模剂
技术领域
本发明涉及一种混凝土脱模剂，具体是一种生物柴油混凝土脱模剂。
背景技术
混凝土预制构件或预制品,如砌块、板、梁、墩、坝、桥等,在其浇灌过程中,必须使用模板或模具。为了使硬化后的混凝土易于脱模而不损坏模板,在模板或模具上常涂刷一层脱模剂。长期以来,国内常采用机油、废机油、乳化机油等或动植物油脚、劣质油经皂化而成的所谓液体皂剂作为脱模剂。脱模剂的种类主要有以下几种：
1、纯油类。包括各种植物油、动物油和矿物油均可配置脱模剂。但目前大多采用矿物油。即石油工业生产的各种轻质润滑油，如机械油等。为了降低成本，不少单位使用工业的废机油，不过废机油中杂质较多，更容易污染混凝土表面。某些废机油中还可能含有硫酸、聚氯联苯等有害于混凝土和模版的物质。
2、乳化油类。乳化油大多数用石油润滑油、乳化剂、稳定剂配制而成，有时还加入防锈添加剂。用乳化剂代替纯石油润滑油，不但可以节约大量油料，而且可以提高脱模剂质量，降低脱模成本。这类脱模剂可分为油包水（W/O）型和水包油（O/W）型。一般用于钢膜，也可用于木模上。涂刷后容易干燥，有的干燥后结成薄膜可以反复应用多次，既省工、又省料，大大降低脱模成本。
3、石蜡类。石蜡具有很好的脱模性能，将其加热熔化后，掺入适量溶剂搅匀即可使用。石蜡脱模剂可用于钢、木模板和混凝土台座上，石蜡含量较高时往往在混凝土表面留下石蜡残留物，有碍于混凝土表面的粘结，因而其应用范围受到一定限制。
4、脂肪酸类。这类脱模剂一般含有溶剂、例如汽油、煤油、苯、松节油等。该脱模剂具有良好的脱模和防锈性能，不污染混凝土表面，耐雨水冲刷，每涂一次可使用三次。脂肪酸类脱模剂大多同混凝土的碱（游离石灰）起化学反应。
5、油漆类。这类脱模剂价格较高，但可以反复使用多次，经济上还是适宜的。如醇酸清漆脱模剂。
