Wall coating and preparation method

Abstract

The invention discloses a wall coating. The coating comprises the following components by weight: 200-400 parts of water, 10-40 parts of pulp mixtures, 2-4 parts of foam killers, 50-150 parts of titanium dioxide, 100-350 parts of synthetic resin emulsion, 2-5 parts of acid-alkali modulation agents, 20-50 parts of vegetable gelatin compositions and 3-5 parts of plant extracts. According to the invention, the pulp mixtures are adopted, so that the cost is relatively low, and the technology is simple; the synthetic resin emulsion, the plant extracts and vegetable gelatin are cooperatively adopted for achieving the effects of mold prevention, desinsectization and sterilization, so that the wall coating has fresh smell; composite alkali with high alkalinity can be used for adjusting PH values, has the effects of emulsion breaking and coagulation improving, can form hydroxide precipitation with heavy metals to remove the heavy metals, and is good for health and environment protection; the coating is free from toxic substances of formaldehyde, benzene, ammonia and the like, and volatile toxic substances reach zero emission; the coating is an internal wall coating that is nontoxic, environment-friendly and low in manufacturing cost, has the antibacterial effect, and generates no adverse impacts 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...
