The invention relates to the technical field of dispersing aids, in particular to a dispersing aid for powder processing, which comprises an emulsifier, salt, titanium dioxide, a water-soluble initiator and water which are combined to obtain an aqueous dispersion, the aqueous dispersion is compounded and combined to form high-transparency gel, exchangeable particles are fully distributed on the surface of the aqueous dispersion, the long-term stable and uniform distribution of the composition can be maintained, and when the composition is added into powder processing, electrostatic repulsive force is generated on the surfaces of powder particles, the powder particles are uniformly dispersed and do not float or sink, sedimentation and thickening of particulate matters in the powder are avoided, the powder can be kept stable, when being applied to powder processing of concrete products, rammed earth house walls, yellow mud brickmaking, stone powder brickmaking, artificial inorganic stone manufacturing and the like, the powder can be directly added together with other auxiliaries, the mechanical property, transparency, surface processing performance and the like of products are improved, the raw materials are simple and easy to obtain, the cost is low, the using effect is good, and the large-scale industrial application requirement is met.
本发明涉及分散助剂技术领域，具体涉及一种粉体加工用分散助剂，包括乳化剂、盐、二氧化钛、水溶性引发剂和水，通过以上组合，得到水性分散体，其本身通过复配组合形成具有高透明度的凝胶，在表面布满可交换的粒子，可保持组合物本身的长期稳定均匀分布，将其加入粉体加工中，使粉体颗粒表面产生静电斥力，均匀分散，不会上浮或者下沉，避免粉体中颗粒物质的沉降和返粗，可使粉体可以保持稳定，将其应用于砼类制品、夯土房墙体、黄泥制砖、石粉制砖及人造无机石制造等粉体加工时，可直接与其它助剂一同加入，提高制品的力学性能、透明度和表面加工性能等，其原料简单易得，成本低廉，使用效果好，满足工业化的大量应用需求。
