Interior wall spray putty and its application method

Abstract

The invention discloses an inner wall spraying putty which comprises the following materials: white cement, slaked lime, heavy calcium carbonate, cellulose ether, polymer powder, a thixotropic agent, a water reducer, a moisture repellent, a defoaming agent and wood fiber. The invention also discloses a method of using the inner wall spraying putty. The method comprises the following steps of: mixing the inner wall spraying putty with clean water, stirring the mixture to be at a uniform block-free state, standing for two minutes, and then stirring for 30 seconds. The inner wall spraying putty has a reasonable formula, and is green due to no using of 107 or 108 glue and containing no formaldehyde, the sprayed putty is flat and smooth, has a firm surface, is unlikely to dust and craze, has good water resisting property, is easily stirred uniformly, free from obvious blocks, less in spraying resistance and strong in constructability, is particularly suitable for mechanized construction, ensures the spraying effect, and also greatly improves the construction efficiency. The method provided by the invention has simple technique steps, and is easy to realize and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of interior wall putty, and in particular relates to an interior wall spray putty and a using method thereof. Background technique [0002] In recent years, a new type of interior wall putty construction machinery is quietly entering the construction field. This kind of machinery is airless spraying equipment, represented by Graco in the United States and Wagner in Germany. Using this equipment, the construction efficiency can be increased by more than 10 times, the construction speed is fast, the construction quality is good, and 2 / 3 of the labor can be saved in large quantities, and the comprehensive benefits are very considerable. [0003] At present, most of the putty sprayed by machines are interior wall putty. The formula of interior wall putty is simple. Basically, it is Shuangfei powder mixed with 107 or 108 glue, and some use Shuangfei powder and pregelatinized starch. Many problems have been expo...

AI Technical Summary

Problems solved by technology

Many problems have been exposed during the use of these putties: 1. The cohesion of the putty is poor, the putty is relatively dry, and the pumping resistance is large, resulting in heavy mechanical load and increased mechanical loss

2. The dispersion of the powder in the putty is not good, it is easy to agglomerate, there are many small particles, and the nozzle is often blocked, which affects the continuity of the construction

3. Because the putty is relatively viscous, a large number of air bubbles are brought into it during high-speed stirring. After spraying on the wall, the number of pores is large, which seriously affects the appearance

4. Due to the use of 107 or 108 glue, the water resistance of this type of interior wall putty is poor. At the same time, 107 and 108 glue contain a large amount of formaldehyde, which has a serious impact on human health
