Novel concrete coloring agent
The invention provides a novel concrete coloring agent. The novel concrete coloring agent is prepared from the following components in percentage by mass: 2-10% of nano metal complex dye, 5-20% of nano silicon dioxide, 5-20% of small molecular resin, 45-88% of a solvent, 0.1-0.3% of a defoaming agent, 0.1-0.3% of a dispersing agent, 0.1-0.3% of a light stabilizer, 0.1-0.3% of an ultraviolet light absorber and 0.1-0.5% of a dehydrating agent. According to the invention, the solvent, the nano silicon dioxide and the small molecule resin are wrapped with the dye for three-step permeation distribution, so that the problems of dye migration caused by water and color fastness reduction caused by energy transition discoloration generated by illumination are solved, the dyeing effect of the concrete is realized, and the excellent performances of sealing, hardening, water resistance, wear resistance and durability are realized.
本发明提供了一种新型混凝土染色剂，由按质量百分数计的以下组分制得：纳米金属络合染料2～10％、纳米二氧化硅5～20％、小分子树脂5～20％、溶剂45～88％、消泡剂1～3‰、分散剂1～3‰、光稳定剂1～3‰、紫外线吸收剂1～3‰、脱水剂1～5‰。本申请中溶剂、纳米二氧化硅、小分子树脂裹挟染料进行三阶梯渗透分布，解决了水分导致的染料迁移和光照产生的能量跃迁变色导致的色牢度下降的问题，实现混凝土的染色效果，并实现具有密封、硬化、耐水、耐磨、耐久性能的优质性能。
