Abstract

The invention discloses an efficient-spraying type dry-mixing and wet-mixing mortar plasticizer composition as well as a preparation method and an application method thereof. The composition comprises the following components in percentage by weight (100% in total): 1%-5% of a plasticizer, 15%-30% of a thickening agent, 30%-50% of a retarder, 10%-25% of an anti-cracking agent, 1-5% of a water-retaining agent, 5%-10% of an enhancer, and 1%-5% of a binding agent. By utilizing the composition, the workability, water-retaining property, adhesive property and cracking resistance of coating mortar can be remarkably improved, the cracking, hollowing and falling of the mortar are avoided, and various performance indexes such as the strength and permeability resistance of the mortar can be improved; and furthermore, cement can be saved, and the disadvantages of easiness in ash blasting, high shrinkage, low strength and the like of the cement mixed mortar are overcome.

Description

technical field [0001] The invention relates to a high-efficiency spray dry-wet mixing mortar plasticizer composition and a preparation method and an application method thereof. Background technique [0002] Construction mortar is used in a large amount in construction engineering and has a wide range of uses. It is a building material second only to concrete in modern engineering construction. Plastering mortar refers to the mortar that is applied on the surface of buildings or building components, and one or more layers of mortar are applied on the walls, ceilings, and ground planes with a specified thickness, and the final properties are obtained after hardening. The plastering mortar is required to have good workability, easy to spread into a uniform and flat layer, easy to construct, and have high adhesive force. The mortar layer should be firmly bonded to the bottom surface, and it will not crack or crack after long-term use. In general, it should also have the perfor...
