AI Technical Summary

Problems solved by technology

If the material ratio is not strictly controlled, the product quality will fluctuate greatly, which will easily lead to poor bonding, poor impermeability, peeling, blistering, hollowing and other construction quality problems
At present, there are two production methods for exterior wall putty: one is manual weighing, and single-batch production at intervals. The advantages of this method of production are accurate weighing and stable product quality. High; the other is the use of automated continuous production process
This method solves the shortcomings of the former method, but due to the large variety of functional additives and the small amount of feed, it is difficult to achieve the required weighing accuracy, and there is vibration in the automated production line, it is very easy to produce material ratio errors, resulting in product failure. unqualified

Abstract

The invention discloses exterior wall putty suitable for machine spraying and a production method thereof. The exterior wall putty is prepared from raw materials in parts by weight as follows: 55-65 parts of heavy calcium carbonate, 20-30 parts of white cement, 8-12 parts of quartz sand, 0.3-0.4 parts of cellulose ether, 1.6-1.8 parts of redispersible latex powder, 0.1-0.2 parts of starch ether, 0.4-0.6 parts of attapulgite, 0.1-0.2 parts of sodium polycarboxylate, 0.05-0.15 parts of a defoaming agent and 0.1-0.2 parts of an early strength agent. The exterior wall putty has high adhesion, sagging property and anti-permeability and is suitable for machine spraying. With the adoption of the exterior wall putty, the construction stability of machine spraying can be substantially improved, andbuilding quality problems such as peeling, blistering, hollowing, cracking and the like of an exterior wall are effectively solved.

Description

technical field [0001] The invention relates to the technical field of production of building materials, in particular to an exterior wall putty suitable for machine spraying and a production method thereof. Background technique [0002] External wall putty is a new type of material produced by professional manufacturers for leveling and decorating external walls. The traditional exterior wall putty construction is manual, labor-intensive, and construction cost is high. Compared with ordinary exterior wall putty, machine-sprayed exterior wall putty has stable and guaranteed quality. The construction process is environmentally friendly and pollution-free, with low labor intensity and high construction efficiency. However, new requirements are put forward for the adhesion and sagging of the product. [0003] The production of exterior wall putty needs to add various functional additives, and there are many types of additives, and the blending ratio is very small such as a few...
