Abstract

The invention relates to a multifunctional ecological exterior wall coating. The multifunctional ecological exterior wall coating is prepared from the following raw materials in parts by weight: 30-60 parts of silica sol, 30-50 parts of alkaline mud, 4-7 parts of titanium dioxide, 2-7 parts of zinc oxide, 1-5 parts of a coalescing agent and 1-3 parts of defoaming agent. According to the multifunctional ecological exterior wall coating, the alkaline mud is used to prepare the ecological coating, the production cost is very low, the cost of the ecological coating is greatly reduced and the ecological coating has relatively large price advantage and quality assurance. The prepared exterior wall coating has the characteristics of UV radiation resistance, air purification, corrosion resistance, scratching resistance, temperature regulation and control, good stain resistance and the like. The preparation method is simple in configuration process and has the effects of environmental friendliness and low carbon.

Description

technical field [0001] The invention relates to the field of functional coatings, in particular to a multifunctional ecological exterior wall coating, and also relates to a preparation method of the coating. Background technique [0002] Alkali slag is the waste residue discharged from the production of soda ash by the ammonia-soda method. It is one of the world's recognized public hazards, with an annual discharge of about 200 million tons worldwide. my country's annual slag discharge exceeds 30,000 cubic meters. A large amount of waste residue liquid accumulates all year round, which not only takes up a lot of land, but also pollutes the environment. Countries around the world have done a lot of research work on the comprehensive treatment of alkali slag, but the industrial implementation has not yet been realized. my country's research work on alkali slag has made great progress, such as the Chinese patent CN201410223791 "A method for preparing heavy metal adsorbents us...
