Concrete brightening agent and preparation method thereof
The invention discloses a concrete brightening agent and a preparation method thereof. Comprising the following components in parts by weight: 100 to 140 parts of hydrophilic unsaturated carboxylic ester, 70 to 100 parts of lipophilic unsaturated carboxylic ester, 0.5 to 2 parts of modified single-walled carbon nanotubes, 8 to 14 parts of glycol distearate, 5 to 9 parts of an imidazoline compound, 2 to 7 parts of polyglycerol fatty acid ester, 6 to 12 parts of a nonionic surfactant, 18 to 35 parts of a fluorocarbon surfactant, 5 to 9 parts of a molecular regulator, 3 to 8 parts of an initiator and 664 to 783 parts of water. The concrete brightener can be matched with an additive for use during concrete prefabrication, a cement product using the concrete brightener is smooth in surface, more uniform in color and capable of keeping a long-term bright effect, meanwhile, strong adsorption and dispersion effects on cement are achieved, the strength and surface hardness of the cement product are improved, and the service life of the cement product is prolonged. Meanwhile, the preparation conditions are mild, no organic solvent is used in the synthesis process, and safety and environment friendliness are achieved.
本发明公开一种混凝土增亮剂及其制备方法，包括如下重量份数的各组分：亲水性不饱和羧酸酯100～140份、亲油性不饱和羧酸酯70～100份、改性单壁碳纳米管0.5～2份、乙二醇二硬脂酸酯8～14份、咪唑啉化合物5～9份、聚甘油脂肪酸酯2～7份、非离子表面活性剂6～12份、氟碳表面活性剂18～35份、分子调节剂5～9份、引发剂3～8份、水664～783份。本发明可以在混凝土预制时与外加剂配合使用，使用该混凝土增亮剂后水泥制品表面平滑，颜色更均匀，可以保持长久的光亮效果，同时实现对水泥强烈的吸附和分散作用，提高水泥制品强度和表面硬度，增强水泥制品表面光亮度、光洁度及耐磨性，同时，本发明制备条件温和，合成过程中不使用任何有机溶剂，安全环保。
