Aliphatic water reducer
The invention belongs to the technical field of water reducing agents, and particularly relates to an aliphatic water reducing agent. The technical effect of reducing the color of the final product is achieved through the main body reagent, the dispersive reagent for reducing the color of the main body reagent and the reducing reagent for reducing the color of the main body reagent and reducing the loss speed of the dispersive reagent in the concrete. The water reducer has the beneficial effects that the dispersive reagent has a relatively high xi potential value and plays a role in dispersing colored particles of the main reagent, so that the overall color and luster of the water reducer are reduced; the reducing reagent enables the colored particles in the main reagent to be reduced into colorless molecules through a reduction effect; the dispersing reagent and the reducing reagent are mixed to generate naphthalene sulfonic acid to further disperse and reduce the color depth of the water reducing agent; and polyaluminum chloride and naphthalene sulfonic acid are matched to disperse the colored particles and then have a bridging effect, so that the colored particles are prevented from re-aggregation, and the effect of high color fading is achieved.
本发明属于减水剂技术领域，尤其涉及一种脂肪族减水剂。本发明通过主体试剂，用于降低主体试剂颜色的分散性试剂，以及降低主体试剂颜色并且减少分散性试剂在混凝土中流失速度的还原性试剂起到了降低最终产物色泽的技术效果。本发明的有益之处在于分散性试剂具有较高的ξ电位值，起到了分散主体试剂有色粒子的作用，使得减水剂整体色泽降低；还原性试剂通过还原作用使得主体试剂中有色粒子被还原为无色分子；分散性试剂与还原性试剂混合生成萘磺酸起到进一步分散的作用降低减水剂颜色深度；以及聚合氯化铝与萘磺酸配合将有色粒子分散后桥联作用，阻止有色粒子重新聚集，达到了高度褪色的效果。
