The invention belongs to the technical field of functional coatings, and particularly relates to a concrete negative surface treating agent and a preparation method and application thereof, and the concrete negative surface treating agent comprises the following components in parts by mass: 450-550 parts of filler, 450-550 parts of water, 15-25 parts of graft modified starch ether, 0.3-40 parts of hydration inhibitor, 98-102 parts of styrene-acrylic emulsion, 1-6 parts of inorganic pigment, 0.5-0.7 part of antirust agent, 0.1-0.7 part of defoaming agent, 0.3-0.8 part of drier and 0.1-0.3 part of preservative. The prepared surface treating agent is sprayed on the inner surface of a mold, concrete can lose efficacy for a long time on the inner surface of the mold, the sprayed surface treating agent has good hardness and anti-vibration performance after forming a film, meanwhile, the weather resistance is good, and the effect that the depth of textures is controllable can be achieved by adjusting the raw material ratio.
本发明属于功能涂料技术领域，特别涉及一种混凝土负向表面处理剂及其制备方法与应用，包括如下质量份组分：450～550份填料、450～550份水、15～25份接枝改性淀粉醚、0.3～40份水化抑制剂、98～102份苯丙乳液、1～6份无机颜料、0.5～0.7份防锈剂、0.1～0.7份消泡剂、0.3～0.8份催干剂和0.1～0.3份防腐剂。本发明制得的表面处理剂喷涂于模具内表面能够使混凝土于模具内表面处长久失效，且喷涂的表面处理剂成膜后具有较好的硬度和抗振捣性能，同时耐候性较好，通过调整原料配比还能够实现纹理深浅可控的效果。
