Abstract

The invention discloses water-based colourful building coating. The water-based colourful building coating is formed by mixing the following components in percentage by mass: 5-20% of water-based colour paste, 60-70% of colour chip system and 30-40% of emulsion binder. A preparation method of the water-based colourful building coating comprises the following steps: preparing basic paint, matching colour, preparing a protection glue system, preparing a colour chip system, preparing an emulsion binder, and adding the colour chip system into the prepared emulsion binder, thus the stable water-based colourful building coating is formed. The water-based colourful building coating has the advantages that the protection glue system and cellulose in the basic paint interact with each other, so that produced gel is firmly wrapped on the surface of the basic paint of each colour, and surface activity of negative ions provides negative charges to form stable colour chips in various colours; the water-based colourful building coating can improve colour chip stability and storage stability, can prevent precipitation, colour bleeding and muddy water of the water-based colourful particles, is moulded by spraying in one step, good in recoatability, realistic in natural marble imitating effect and simple to maintain, has certain elasticity and can be used for making up micro cracks of a wall body.

Description

technical field [0001] The invention relates to an architectural paint, in particular to a water-based colorful architectural paint and a preparation method thereof. Background technique [0002] At present, granite and marble are favored by architects and users for their serious texture and durable quality, and they are also one of the important symbols of the external image of buildings. However, with the protection of natural resources and the implementation of national building energy conservation in my country, the wide application of natural stone in the field of architectural decoration has been affected to a certain extent. The construction of granite as a building decoration material is relatively complicated, which not only increases the load bearing of the unit wall, but also has many unsafe factors such as the risk of falling off; some marble will release trace radioactive elements, which is harmful to human health. In addition, the continuous improvement of the...
