Gypsum-based self-leveling agent and preparation method thereof

Abstract

The invention discloses a gypsum-based self-leveling agent and a preparation method thereof. The gypsum-based self-leveling agent comprises the following substances in parts by mass: 45-55% of gypsum;5%-7% of cement; 5%-7% of filler; 30%-40% of sand; 0.5%-0.6% of rubber powder; 0.2%-0.3% of a water reducing agent; and 0.1%-0.2% of a defoaming agent. Gypsum is used as a cementing material, and thegypsum is used for providing hardness and strength required by ground paving engineering; the sand is aggregate, so that the product has high bending resistance and compression resistance; and a heavy calcium carbonate is used as a filler, so that the slurry consistency of the product is proper, bleeding is prevented, the method is simple and easy to implement, and the obtained self-leveling agent has the advantages of high constructability, bending resistance, compression resistance, bonding strength, cracking resistance and strength speed, and has wide application prospects.

Description

technical field [0001] The invention relates to the field of building materials, and relates to a gypsum-based self-leveling and a preparation method thereof. Background technique [0002] Self-leveling mortar is a kind of ground material that is composed of inorganic or organic gelling materials, fine aggregates, fillers and admixtures. It has fluidity after being stirred with water or can be flowed and leveled with a little auxiliary paving. It has fluidity. Large size, fast construction, smooth surface and other advantages, it is an ideal material for the ground paving of large supermarkets, shopping malls, parking lots, factory workshops, warehouses, etc. It is a development direction of building ground construction now, and the market potential is great. [0003] In recent years, with the continuous development of construction technology in our country, people have paid more and more attention to the research of building materials, and have higher and higher requirement...

AI Technical Summary

Problems solved by technology

[0005] At present, in the ground paving, the commonly used cement mortar has the problems of difficult leveling construction, long time for strength, and easy cracking, and the cement mortar is generally mixed by workers on site, and the material ratio is mostly manual ratio by workers based on experience, which is not accurate enough.
