Abstract
The invention belongs to the technical field of building materials and relates to a high efficiency composite pumping aid for house 3D printing slurry. The high efficiency composite pumping aid is prepared from 15-25 parts by weight of a high efficiency polycarboxylic acid water reducer, 20-30 parts by weight of a high efficiency naphthalene water reducer, 1-5 parts by weight of sodium lignosulfonate, 5-10 parts by weight of sodium dodecyl benzene sulfonate, 40-60 parts by weight of borax and 1-5 parts by weight of sodium tripolyphosphate. The high efficiency pumping aid accelerates gelling material solidification, reduces a water-reducing rate by 15-20% and has a less later strength loss. The pumping aid can shorten gelling material demolding time and prevent mold collapse. The pumping aid saves a gelling material by 10-20% and has a lower production cost.
