Abstract

The invention relates to the technical field of dry-mixed mortar, and particularly discloses cement-based self-leveling mortar and a preparation process thereof. The cement-based self-leveling mortar is prepared from the following components in parts by weight: 200 to 300 parts of cement, 20 to 60 parts of gypsum, 50 to 100 parts of sulphoaluminate cement, 0.5 to 1.5 parts of cellulose, 0.8 to 2.0 parts of water reducing agent, 0.5 to 1.0 part of defoaming agent, 0.2 to 0.5 part of coagulation accelerator, 0.5 to 1.2 parts of retarder, 400 to 600 parts of graded sand, 130 to 180 parts of filler, 30 to 50 parts of epoxy resin and 20 to 50 parts of bean flour. The mortar has the advantages of being good in wear resistance and not prone to generating dust.

Description

technical field [0001] The present application relates to the technical field of dry-mixed mortar, more specifically, it relates to a cement-based self-leveling mortar and a preparation process thereof. Background technique [0002] Cement-based self-leveling mortar is made of cement and quartz sand as the main raw materials and additives mixed uniformly by machinery; during construction, it can be used after adding water and mixing on site, and a high-level base surface can be obtained after a little spreading with tools. [0003] The relevant Chinese patent with the publication number CN105936592B discloses a cement-based self-leveling mortar, whose preparation raw materials contain the following components in proportion by weight: Portland cement 350-550, gypsum 350-550, polycarboxylate superplasticizer 5-10, organosilicon concrete defoamer 0.05-0.1, retarder 1-3 and sand material 800-1100, wherein the polycarboxylate water reducer contains a salt (A), and the retarder c...
