Organic-inorganic composite water-based dyed color sand and preparation method thereof
The invention belongs to the technical field of inorganic material dyeing, and discloses organic-inorganic composite water-based dyeing color sand and a preparation method thereof. The dyed colored sand comprises to-be-dyed sand and a dye film layer attached to the surface of the to-be-dyed sand, the sand to be dyed is formed by coating a catalyst solution on the surface of a sand material through stirring; the dye film layer is formed in the mode that organic-inorganic composite water-based dyeing slurry is attached to the surface of sand to be dyed through stirring, the organic-inorganic composite water-based dyeing slurry is cross-linked to form a film on the surface of the sand to be dyed under the action of a catalyst, and then drying and curing are conducted. The organic-inorganic composite water-based dyeing slurry is prepared from the following raw materials: water, a dispersing agent, an inorganic binder, anionic group modified polyvinyl alcohol resin, an inorganic pigment, a defoaming agent and an optional filler. The dyed color sand is easy to industrially produce, the energy consumption in the preparation process is low, and the phenomenon of particle aggregation is not prone to occurring.
本发明属于无机材料染色技术领域，公开了一种有机无机复合的水性染色彩砂及制备方法。所述染色彩砂包括：待染色砂和附着在所述待染色砂表面的染料膜层；待染色砂由催化剂溶液通过搅拌包覆在砂料表面形成；染料膜层由有机无机复合的水性染色浆料通过搅拌附着在待染色砂表面，并且有机无机复合的水性染色浆料在催化剂的作用下在待染色砂表面交联成膜，再经干燥和养护而形成；制备有机无机复合的水性染色浆料的原料包括下组分：水、分散剂、无机粘结剂、阴离子基团改性的聚乙烯醇树脂、无机颜料、消泡剂、任选地填料。本发明的染色彩砂易于工业化生产，制备过程能耗较低，并且不易出现颗粒团聚的现象。
