Problems solved by technology

[0003] At present, the construction process of spraying putty is as follows: first use mechanical spraying to increase the speed of putty on the wall, and then rely on manual scraping and leveling, and the putty sold on the market is not classified according to the construction method, that is, mechanical spraying putty and manual scraping The putty is often mixed, but the putty scraped manually is often thixotropic and has no fluidity. When this kind of putty is mechanically sprayed, it is easy to

Abstract

The invention relates to a machine-sprayed putty material and a preparation method thereof. The machine-sprayed putty material is prepared from the following raw materials: 0.5-35 parts of a base material; 0.05-0.5 part of a water reducing agent; 0.1-0.6 part of cellulose ether; 0.02-0.2 part of modified hydroxypropyl starch ether; 65-90 parts of a filler; wherein the water reducing agent is selected from a naphthalene water reducing agent and/or a melamine water reducing agent; the viscosity of the cellulose ether at the temperature of 20 DEG C is 20,000 mPa * s to 40,000 mPa * s; the substitution degree of the modified hydroxypropyl starch ether is 0.05-0.08, and the viscosity at 20 DEG C is 400 mPa.s to 1200 mPa.s. The putty material is suitable for mechanical spraying and good in leveling property, the construction efficiency can be improved, the mechanical loss of spraying equipment is reduced, the construction continuity is improved, and a flat and smooth coating can be formed without manual leveling after the putty material is sprayed on a wall.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a machine-sprayed putty material and a preparation method thereof. Background technique [0002] High-pressure airless spraying has brought technological innovation to putty construction. Mechanical spraying has the following advantages: it can reduce ground ash and avoid excessive loss of putty; the construction is more convenient, and the spraying of the roof can be completed without scaffolding, and there are no construction dead angles, yin and yang corners , walls and other positions can be sprayed; construction efficiency is high, a spraying machine can spray 800-1000 square meters per day, which is equivalent to the workload of 15 skilled workers a day, which greatly shortens the construction period, reduces labor intensity, and saves scaffolding, etc. Expenses for turnover materials. With the continuous increase of labor costs, mechanical spraying can greatly save the m...
