Abstract

The invention discloses a high-water-reducing-rate low-cost polycarboxylate superplasticizer and a preparation method thereof, wherein the high-water-reducing-rate low-cost polycarboxylate superplasticizer is prepared from the following raw materials by weight: 3548 parts of a base material, 652.5 parts of a material A, 830 parts of a material B and 650 parts of supplemented water. According to the invention, the preparation method is simple, low in cost, convenient to operate and beneficial to large-scale industrial production; the prepared polycarboxylate superplasticizer has high water reducing effect; after a concrete mixture is added, the polycarboxylate superplasticizer has a dispersing effect on cement particles so as to improve the workability, reduce the unit water consumption, improve the flowability of the concrete mixture, improve the quality of concrete and improve the actual use effect of the concrete.

Description

technical field [0001] The invention relates to the technical field of preparation of polycarboxylate water reducers, in particular to a polycarboxylate water reducer with high water reducing rate and low cost and a synthesis method thereof. Background technique [0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. Most of them are anionic surfactants, such as lignosulfonate, naphthalenesulfonate formaldehyde polymer, etc. After being added to the concrete mixture, it can disperse the cement particles, improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement. [0003] The water reducing agent in the market now has a low water reducing rate, and the preparation process is complicated, and the preparation cost is high, so it cannot meet the needs of users. Contents of the inven...
