Problems solved by technology

The original paint was solvent-based paint, but solvent-based paint polluted the environment and cost high. In the 1950s, water-based latex paint appeared. Water-based latex paint has no pollution to the surrounding environment, low organic volatile emissions, and is safe and environmentally friendly. However, this paint It is easy to bubble, the surface tension of water is high, and the strong mechanical action during use will destroy its stability. In the 1970s, water-based inorganic coatings were studied. It has excellent environmental protection performance, its raw materials come from a wide range of sources, the preparation process is simple, and its comprehensive performance is also high. , so more and more people pay attention to
However, due to the short development time, there are still some defects in the process of preparation and application, such as poor water resistance, easy to return to alkali when applied to cement substrates, and insufficient antibacterial properties.

Abstract

The invention relates to inorganic antibacterial coating and a preparation method thereof and belongs to the technical field of building coating. The inorganic antibacterial coating provided by the invention is mainly prepared from the following components in parts by weight: 20 to 50 parts of a silicon-containing inorganic binding agent, 5 to 10 parts of inorganic oxide electret crystal whiskers,5 to 20 parts of silver ion loading type diatomite, 10 to 30 parts of inorganic pigment and filler, 0.1 to 1 part of a stabilizer, 0.5 to 3.5 parts of an auxiliary agent and 12 to 24 parts of water.According to the inorganic antibacterial coating provided by the invention, the stability and dispersity of the coating are ensured, and the antibacterial performance and water resistance of the coating are improved.

Description

technical field [0001] The invention relates to an inorganic antibacterial coating and a preparation method thereof, belonging to the technical field of architectural coatings. Background technique [0002] As a coating material for substrate protection and decoration, paint has gone through several generations of changes and has been developing in the direction of energy saving, environmental protection, health, and functional diversity. The original paint was solvent-based paint, but solvent-based paint polluted the environment and cost high. In the 1950s, water-based latex paint appeared. Water-based latex paint has no pollution to the surrounding environment, low organic volatile emissions, and is safe and environmentally friendly. However, this paint It is easy to bubble, the surface tension of water is high, and the strong mechanical action during use will destroy its stability. In the 1970s, water-based inorganic coatings were studied. It has excellent environmental p...
