Artificial colored sand and preparation method thereof
The invention discloses artificial colored sand and a preparation method thereof. The artificial colored sand comprises sand to be dyed and a dye layer attached to the surface of the sand to be dyed, the dye layer is formed in the mode that fast curing solvent-free type alkoxysilyl modified polyether dyeing slurry is attached to the surface of the to-be-dyed sand through stirring and is subjected to curing reaction on the surface of the to-be-dyed sand under the condition that wet and hot air is introduced; the raw materials for preparing the fast-curing solvent-free type alkoxysilyl modified polyether dyeing slurry comprise alkoxysilyl modified polyether polymer resin, a dispersion stabilizer, a pigment, a plasticizer, a dehydrating agent, a silane coupling agent, a catalyst, an optional filler, an optional thixotropic agent and an optional weather-resistant additive. According to the preparation method, industrial production is easy, the energy consumption in the preparation process is low, and the phenomenon of particle aggregation is not prone to occurring; the prepared colored sand has good weather resistance, is not easy to fade and has good color generation.
本发明公开了一种人工彩砂及其制备方法，该人工彩砂包括：待染色砂和附着在所述待染色砂表面的染料层；所述染料层由快速固化无溶剂型烷氧硅基改性聚醚染色浆料，通过搅拌附着在所述待染色砂表面，并在通入湿热空气的条件下在所述待染色砂表面发生固化反应形成；制备快速固化无溶剂型烷氧硅基改性聚醚染色浆料的原料包括：烷氧硅基改性聚醚高分子树脂、分散稳定剂、颜料、增塑剂、脱水剂、硅烷偶联剂、催化剂、任选的填料、任选的触变剂和任选的耐候助剂。本发明的制备方法易于工业化生产，制备过程能耗较低，并且不易出现颗粒团聚的现象；所制备的彩砂具有良好耐候性能，不易褪色，呈色好。
