Abstract

The invention discloses a pulverized fuel ash outer wall flexible putty powder which is prepared by mixing the following raw materials by the mixture ratio (based on parts by weight): 10 parts of cement, 70 parts of pulverized fuel ash, 15 parts of ash calcium powder, 1.8 parts of excitant, 1.5 parts of latex powder, 0.2 part of hydroxypropyl methyl cellulose, 0.4 part of water reducing agent and 0.1 part of defoaming agent; wherein the cement is 42.5 ordinary portland cement; the pulverized fuel ash is I-level pulverized fuel ash; the ash calcium powder has the fineness of 200 meshes; the excitant is the mixture of anhydrous sodium sulfate and calcium sulfate; the water reducing agent is naphthaline-series powder water reducing agent; the latex powder is the copolymer of vinyl ester of versatic acid and vinyl acetate; and the raw materials are tested and measured according to the formulation and then poured into a powder mixing machine to be evenly mixed. The putty powder has better water-resistant, alkali-resistant and adhesive properties, and is simple in production technique, low in cost and beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flexible putty powder for external walls of fly ash. Background technique [0002] There are many types of flexible putty powders for exterior walls. High-grade flexible coatings have two-component or one-component materials. The main forming materials are polymer emulsion or latex powder and fillers. However, there are generally defects such as cracking, shelling, falling off, poor water resistance and poor sanding performance. Contents of the invention [0003] In view of this, the purpose of the present invention is to overcome the defects of the prior art, to provide a flexible putty powder for external walls of fly ash, to improve its water resistance, alkali resistance, and bonding performance, and its production process is simple, cheap, and beneficial Environmental friendly. [0004] To achieve the above object, the present invention adopts the following ...
