Dry-mixed mortar thickening agent and preparation method thereof
The invention relates to a building material. The invention aims to provide a dry-mixed mortar thickening agent and a preparation method thereof. The dry-mixed mortar thickening agent provided by theinvention has the characteristics of the low cost, the good water reducing effect, the good retarding effect and low air entraining. The preparation method provided by the invention has the characteristics of the simple process and convenience in preparation. According to the technical scheme, the dry-mixed mortar thickening agent is characterized by comprising the following components in parts bymass: 40-60 parts of a thickening agent base material A, 35-55 parts of a thickening agent base material B, 0-5 parts of hydroxymethyl cellulose, and 2-5 parts of sodium hydroxide and 5-10 parts of zeolite powder, wherein the thickening agent base material A comprises maltodextrin, polyethylene glycol and molasses in a mass ratio of (1-2):(2-4):(6-10), and the thickening agent base material B comprises carbonyl pyroaldehyde and sodium lignin sulfonate in a mass ratio of (25-30):(1-5).
