Embodiment 1

[0027] Each component of the present invention is taken by weighing the mass percentage listed in the following table 1:

[0028] Component Proportion (mass percentage (%)) sodium gluconate 55.0 polyethylene oxide 20.0 Polycarboxylate superplasticizer 21.0 Sodium chloride 2.0 calcium lignosulfonate 2.0

[0029] Preparation process: Weigh each component according to the above mass percentage, add it to the mixer, mix well and evenly, and then the corresponding product can be obtained.

Embodiment 2

[0031] Each component of the present invention is taken by weighing the mass percentage listed in the following table 2:

[0032] Component Proportion (mass percentage (%)) sodium gluconate 54.0 polyethylene oxide 21.0 Polycarboxylate superplasticizer 22.0 Sodium chloride 1.0 calcium lignosulfonate 2.0

[0033] The preparation process is the same as in Example 1.

Embodiment 3

[0035] Each component of the present invention is taken by weighing the mass percentage listed in the following table 3:

[0036] Component Proportion (mass percentage (%)) sodium gluconate 56.0 polyethylene oxide 19.0 Polycarboxylate superplasticizer 21.0 Sodium chloride 2.0 calcium lignosulfonate 2.0

[0037] The preparation process is the same as in Example 1.

Abstract

The invention belongs to the technical field of building materials, and particularly relates to a long-acting plastering mortar additive and application thereof. The additive is composed of sodium gluconate, polyoxyethylene, a polycarboxylic acid water reducing agent, sodium chloride, calcium lignosulphonate and the like. The long-acting plastering mortar additive is reasonable in formula, can effectively improve the workability and mechanical properties of the mortar, has obvious advantages, overcomes the common fault in the quality of the traditional building mortar, and can satisfy the quality requirements for walling material construction.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a long-acting plastering mortar additive and its application. Background technique [0002] Construction mortar is an indispensable main material in construction engineering. It is divided into two categories: ordinary mortar and special mortar. Among them, ordinary mortar includes three types: masonry mortar, plastering mortar, and ground mortar. Special mortar includes waterproof mortar and ceramic tile. Adhesive mortar, interface treatment mortar, self-leveling mortar, grouting mortar, etc. Among them, ordinary mortar is the most used and accounts for the largest proportion. [0003] Most domestic construction mortars are mixed on-site. This method has disadvantages such as high construction intensity, labor-intensive, poor quality stability, and environmental pollution. In recent years, in order to improve and stabilize the quality of mortar, realize c...
