Problems solved by technology

[0005] At the present stage of machine spraying, due to the different raw materials and proportions of mortar in various places, the performance of actual machine sprayed mortar is not very ideal. Therefore, a mortar admixture is urgently needed to improve direct machine spraying. Improve the construction performance of mortar, improve engineering quality, and improve work efficiency, making the efficiency of machine spraying mortar significantly higher than manual application, and easier to promote

Abstract

The invention relates to an additive for spraying plastering mortar. The additive is prepared from the following raw materials in parts by weight: 50-65 parts of a thickening thickener, 2-8 parts of an air entraining agent, 15-40 parts of a strength excitant, 2-10 parts of a thickening time control agent and 20-45 parts of an expansive antimitotic agent, wherein the thickening thickener is selected from one or more of polyacrylamide, redispersible powder, polyvinyl alcohol, hydroxymethyl cellulose ether, carboxymethylcellulose ether and the like; and the air entraining agent is selected from one or more of sodium dodecyl sulfate, sodium abietate and triterpenoid saponin. According to the additive provided by the invention, the mortar has sprayability and can be firmly attached to the wall space and is not sticky to a cutter, so that leveling construction is facilitated.

Description

technical field [0001] The invention relates to an admixture for spraying lime mortar, in particular to an admixture used in dry-mixed mortar and ready-mixed concrete, and belongs to the technical field of building materials. Background technique [0002] With the continuous development of society, labor costs are getting higher and higher, and the requirements for engineering construction quality and construction efficiency are also getting higher and higher. Spraying lime mortar admixtures can make machine spraying mortar possible, and significantly improve the spraying mortar. Quality and efficiency make the plastering of interior and exterior wall mortars better in quality, higher in efficiency, and safer in construction. It can save more than 80% of manpower. It has huge economic benefits. [0003] Comparison of the actual use effect of a construction site: [0004] project Artificial face Machine spraying without additives Machine spraying with...
