Liquid-state stabilizer for pumping type wet stirring mortar with characteristics of high adhesion and low shedding, and preparation method thereof

Abstract

The invention relates to the technical field of concrete production, particularly to a liquid-state stabilizer for pumping type wet stirring mortar with characteristics of high adhesion and low shedding, and a preparation method thereof, wherein the liquid-state stabilizer comprises, by mass, methacrylic polyether, hydroxypropyl methylcellulose ether, an air entraining agent, a retarder, and the balance of water. According to the present invention, the liquid-state stabilizer can meet the pumpability of the wet stirring mortar, the large-area shedding cannot occur after the obtained wet stirring mortar is sprayed on the wall body, and the obtained wet stirring mortar has characteristics of high water retention and ultra-retardation setting property.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a liquid plastic stabilizer for high-bonding and low-drop pumping type wet-mixed mortar and a preparation method thereof. Background technique [0002] Mixed mortar is a mortar made by mixing cement, sand, mineral admixtures, water, and functional admixtures in a certain proportion in a mixing station. At present, it is mainly wet-mixed plastering mortar, wet-mixed masonry mortar and waterproof mortar. The production and distribution methods of wet-mixed mortar require that the mortar has a long enough operating time, so the wet-mixed mortar needs to have good plasticity and stability, high water retention and long setting time, and it will not condense before use. No segregation and no bleeding. For these special performance requirements of wet-mixed mortar, it is necessary to add admixtures with water retention, retarding, and thickening functions to meet them. With...

Problems solved by technology

[0003] At present, there have been some wet-mixed mortar plastic stabilizers on the market, among which two kinds of powdery mortar plastic stabilizers have been introduced in Chinese patents CN102153311A and CN103449754A, which are better for manual mixing, but due to the small amount of mixing, only Manual metering and feeding are not suitable for large-scale mechanized production. Although Chinese patent CN105601151A and Chinese patent CN104556812A are liquid and can be produced in a large scale, they are sprayed on the wall by pumping during use and then fall off in large areas.
