A kind of wall coating and preparation method thereof

Abstract

The invention discloses a wall paint, which is composed of the following components by weight: 200-400 parts of water, 10-40 parts of pulp mixture, 2-4 parts of defoaming agent, 50-150 parts of titanium dioxide, synthetic 100-350 parts of resin emulsion, 2-5 parts of acid-base modifier, 20-50 parts of plant gum composition, and 3-5 parts of plant extract. The cost of pulp mixture is low and the process is simple. Synthetic resin emulsion, plant extracts and plant glue are used together to prevent mildew, insect repellent and sterilization, and have a fresh smell; Demulsification and improve the effect of coagulation, and can form hydroxide precipitation with heavy metals, remove heavy metals, health and environmental protection, the product of the present invention does not contain toxic substances such as formaldehyde, benzene, ammonia, and volatile toxic substances achieve zero discharge; production cost is low , non-toxic, environmentally friendly and environmentally friendly interior wall coatings with antibacterial effects and no negative impact on human health.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and in particular relates to a wall coating and a preparation method. Background technique

[0002] Coatings play an important role in the national economy and are indispensable in modern society. However, there are more than 10 million tons of volatile organic compounds (VOC) emitted into the atmosphere from paints in the world every year, which is one of the main sources of air pollution. At present, the existing wall paints are usually easy to use during use. The following problems occur: it contains certain harmful substances such as formaldehyde and volatile organic compounds, and usually emits an unpleasant smell for a long time, and the environmental performance is poor, which brings lasting harm to people's bodies. Consumers bring a lot of inconvenience.

[0003] There are also some green paints on the market at present, but the production cost is high and cannot meet the huge market d...
