Abstract
The invention belongs to the technical field of building materials, and in particular relates to a composite retarder for three-dimensional (3D) house printing paste, and a use method of the composite retarder. The composite retarder for the 3D house printing paste is prepared from the following raw materials in parts by weight: 15-35 parts of citric acid, 25-45 parts of boric acid, 5-15 parts of quick lime, 5-10 parts of stearic acid and 10-25 parts of sodium methylene bis-naphthalene sulphonate. The composite retarder for the 3D house printing paste can prolong the initial setting time of a cementing material by 30-100min and prolong the final setting time of the cementing material by 20-80min; the composite retarder for the 3D house printing paste can reduce the temperature rise in a cementing material product and delay the emergence of a temperature peak, thus reducing the temperature stress of the product and improving crack resistance; after the composite retarder for the 3D house printing paste is used, the cementing material can be saved by 10-20%, so that the production cost is greatly lowered.
