Abstract

The invention discloses a reinforced premix mortar moisture-retention thickening agent and a preparation method thereof. The reinforced premix mortar moisture-retention thickening agent is prepared from montmorillonite, kaolin, halloysite, attapulgite clay, fly ash, other admixtures, surfactant and modifier. The preparation method adopts a double grinding method and comprises the following steps: carrying out drying pretreatment on the raw materials; pregrinding the surfactant and the montmorillonite; and carrying out secondary grinding on the other raw materials and the primary grinding raw materials according to parts by mass, thereby obtaining the reinforced premix mortar moisture-retention thickening agent. The invention can obviously improve the workability and water retention property of mortar, greatly lower the cement consumption and effectively enhance the cost performance of the mortar.

Description

technical field [0001] The invention relates to a water-retaining thickener for mortar, in particular to an enhanced water-retaining thickener for ready-mixed mortar, and also relates to a preparation method of the enhanced water-retaining thickener for ready-mixed mortar. Background technique [0002] The rapid development of ready-mixed mortar in the country makes the related technologies of ready-mixed mortar more and more important. Compared with the traditional mortar preparation technology, one of the technical cores of ready-mixed mortar is the mortar additive, which determines the quality, cost and performance of the mortar. It can also be said that the core of whether ready-mixed mortar has market competitiveness depends on the use of mortar additives. [0003] At present, the additives used by domestic enterprises producing ordinary ready-mixed mortar mainly include cellulose ethers, digested lime powder, and water-retaining thickening materials based on non-lime ...
