Abstract

The invention provides a liquid foaming backfilling material for a toilet and a preparation method thereof. The liquid foaming backfilling material is prepared from the following raw materials by weight: 280 to 400 parts of cement, 1 to 3 parts of a liquid foaming auxiliary agent, 2 to 5 parts of calcium formate, 1 to 5 parts of a water repellent, 1 to 2 parts of a water-retaining agent, 0.8 to 1.2 parts of crack-resistant fiber, 0.8 to 2 parts of a thickening agent and 200 to 240 parts of water, wherein the foaming auxiliary agent is at least one selected from the group consisting of an animal cement foaming agent and a plant cement foaming agent. The liquid foaming backfilling material provided by the invention solves the problem of complicated backfilling construction for the toilet dueto factors like a site. The liquid foaming backfilling material prepared by using the method provided by the invention has a bulk density of about 300 to 340 kg / m3, has good degree of flowing in backfilling construction, is tightly bonded with the wall body part of the to-be-backfilled area of the toilet, and has good overall flatness. The liquid foaming backfilling material has a hardening timeof 24 h in summer and about 48 h in winter, and has the advantages of no cracking, no shrinkage, good strength and leakage resistance after hardened. The liquid foaming backfilling material prepared by using the method provided by the invention has a hardening strength of more than 1 MPa and a water absorption rate of less than 30% after 7 days, meets the water absorption performance of 2 to 4 (v / v%), and has good waterproofness.

Description

technical field [0001] The invention relates to a toilet liquid foam backfill material and a preparation method thereof, belonging to the field of foam cement. Background technique [0002] For foamed cement, traditional foaming methods include chemical foaming and mechanical foaming. Chemical foaming uses chemical reaction means to form a relatively uniform porous structure inside concrete or cement products. It can chemically react with certain components in concrete or cement mixture to generate a large amount of gas, and form a porous hardened product after hardening. [0003] Mechanical physical foaming uses the foaming system of the foaming machine to fully foam the foaming agent mechanically, and evenly mix the foam with the cement slurry, and then pass through the pumping system of the foaming machine for cast-in-place construction or mold Forming, a new type of lightweight thermal insulation material with a large number of closed pores formed by natural curing. ...
