Problems solved by technology

Generally, it is not considered to use putty as a decoration material directly. In the usual construction process, after scraping the putty on the wall, then apply primer and topcoat. The primer and topcoat are generally made of organic materials, which will release formaldehyde, Harmful substances such as toluene will not only increase the workload, reduce construction efficiency, waste resources, but also pollute the environment and have a great harmful effect on the human body

Abstract

The invention discloses ecological colorful antibacterial putty powder which comprises the following raw materials in parts by weight: 150-200 parts of heavy calcium carbonate cement, 150-200 parts of white cement, 300-350 parts of coal ash, 50-80 parts of natural color sand, 20-30 parts of a negative ion antibacterial additive, 13-18 parts of redispersible latex powder, 0.1-2 parts of polyacrylonitrile fibers, 0.1-2 parts of hydroxymethyl cellulose and 1-10 parts of inorganic pigment, wherein the negative ion antibacterial additive comprises the following raw materials in parts by weight: 80-120 parts of montmorillonite, 4-10 parts of nano titanium dioxide, 4-10 parts of silver nitrate and 0.1-0.5 part of sodium dodecyl benzene sulfonate. The putty powder is smooth in surface, natural in color, safe and environment-friendly, not only can serve as a base layer leveling material but also can be used for decoration instead of a coating, can continuously release negative ions beneficial to the health of a human body, and also can adsorb harmful impurities and gas and purify air.

Description

technical field [0001] The invention belongs to the technical field of building exterior wall coatings, and in particular relates to an ecological colored antibacterial putty powder. Background technique [0002] Putty powder is a high-performance base leveling material used to remove uneven defects on the wall. The performance of putty powder plays a vital role in wall decoration. Paint can be painted once or several times in a few years, but putty cannot be like this, especially putty for exterior walls, which can only be done at one time. Otherwise, once the exterior wall If there is a quality problem with the putty on it, no matter how good the exterior wall latex paint is, it will not be successful, and it will be difficult and expensive to repair afterwards. [0003] The traditional putty is composed of inorganic cementitious materials (cement, lime calcium, etc.), fillers and inorganic additives. It is white and used for leveling the base. Generally, it is not consi...
