Problems solved by technology

External wall putty powder needs to withstand the test of wind, sun and sun. In order to improve the service life, in the construction process, it often needs to scrape the same place several times to meet the requirements. Although the same kind of putty powder is used in batch scraping, the putty is not One-time forming, the bonding force between each layer of putty powder scraped off is not very strong, and there will be bulging, shrinkage, cracking, etc., which seriously affect the appearance and heat preservation
In order to repair this kind of problem, it is necessary to clean and tidy up the wall as a whole, which greatly increases the cost

Abstract

The invention belongs to the technical field of building materials. The invention provides deep groove stone-like paint putty powder. The deep groove stone-like paint putty powder is prepared from, by mass, 25-35 parts of Portland cement, 45-55 parts of silica sand, 5-15 parts of mineral powder filler and 5-15 parts of reinforcing filler. According to the cement-based putty powder provided by the invention, the silica sand, the mineral powder filler and the reinforcing filler are added, so that the overall binding force of the putty powder is effectively improved, and all the components can be tightly combined together. The putty powder provided by the invention prominently solves the problem that the thickness of three times of batch scraping of a conventional product can be reached by one-time batch scraping, so that the construction difficulty is greatly reduced, and the construction is more efficient; the deep groove stone-like paint putty powder provided by the invention can be applied to a deep groove position, is easy to form in a batch scraping process, does not have the conditions of missing coating, sagging and the like, has good heat preservation and heat insulation effects on a wall body, can ensure the stability of indoor temperature, and meanwhile, avoids the problems of shrinkage cracking and the like caused by non-uniform overlapping thickness of the putty powder in a later period.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a deep groove imitation stone paint putty powder. Background technique [0002] Putty powder is a kind of building decoration material. As a base material for wall repair and leveling, it plays an important role in decoration construction. Putty powder is divided into exterior wall putty powder and interior wall putty powder according to the usage. The two have different components and materials because of different environments. Exterior wall putty powder needs to withstand the test of wind and sun exposure. In order to improve the service life, in the construction process, it often requires multiple batches of scraping for the same place to meet the requirements. Although the same kind of putty powder is used during batch scraping, because the putty is not Once formed, the bonding force between each layer of putty powder scraped in batches is not very strong, and th...
