Abstract

The invention relates to the technical field of building materials, and is a high-waterproof, high-hardness, high-adhesion putty powder for building exterior walls, which is composed of the following raw materials in parts by weight: 20-30 parts by weight of white cement, and 8-20 parts by weight of calcium bicarbonate , talc powder 25~35, gray calcium powder 20~30, paraffin wax 0.08~0.12, quartz powder 5~12, propylamine 0.05~0.1, hydroxypropyl methylcellulose 0.15~0.2, wood fiber 0.05~0.1 rubber powder 0.2~ 0.35, pigment 0.05-0.1, the product formula of the invention is reasonable, the preparation method is simple, and the product performance is excellent, which effectively solves the problem of the low hardness, poor waterproof performance and weak adhesion of the existing putty powder for external walls, which is easy to cause construction workers to repeat construction Or the problem of high wall repair rate; the putty powder coating scraped by the product of the present invention has hardness comparable to that of granite, and good waterproof performance, strong adhesion, and almost zero repair rate, which is suitable for wide application.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high waterproof, high hardness and high adhesion putty powder for building exterior walls. Background technique [0002] Putty powder is a building material with a large amount in architectural decoration. Before painting the wall, putty powder must be used to prime the wall. Traditional putty powder mainly uses white cement and gray calcium powder as raw materials, and generates stable calcium carbonate by self-solidification and absorption of carbon dioxide in the air. Therefore, the calcification reaction of gray calcium powder (calcium hydroxide) in traditional putty powder mainly occurs in putty. The surface layer of the powder coating, and the inner layer of the coating also has a large amount of unstable calcium oxide and calcium hydroxide, which leads to the following problems in the traditional putty powder coating: 1. Poor hardness: the calcification rate i...
