Problems solved by technology

This is mainly because the hardness of the paint film of general products is not high, the product formula PVC (pigment volume concentration) is too high and the paint film requires a matte effect, and the paint film is not dense enough, which makes the paint film easy to be stained and infiltrated and difficult to clean and wipe off.

Abstract

The invention provides environment-friendly and corrosion-prevention coating for buildings and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing silanol modified acrylate-styrene-acrylic emulsion; and secondly, adding polypropylene wax emulsion, pigments and fillers, a corrosion-prevention agent and an auxiliary agent to prepare the coating. The emulsion is the silanol modified acrylate-styrene-acrylic double-component emulsion; the silanol modified emulsion is a film forming substance, and the weather resistance, durability and elasticity of the coating are remarkably improved; the double-component emulsion is used as the film forming substance of a corrosion-prevention material, has the characteristics of good denseness, water resistance and anti-leakage performance, high strength and the like, and also has more excellent adhering property, oil resistance and anti-ageing performance; furthermore, the corrosion-prevention agent is also added into the system so that the corrosion-prevention performance of the coating is improved and the coating can resist mist fog for 3500 h and is not foamed and rusted; and moreover, the polypropylene wax emulsion with special anti-pollution factors is added so that the prepared coating has an obvious anti-pollution effect.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an environment-friendly anti-corrosion architectural coating and a preparation method thereof. Background technique [0002] Coating is a kind of chemical product with convenient construction, low price, obvious effect and high added value rate. It can not only decorate the surface of buildings, ships, machinery, etc., but also has the function of preventing the surface from rusting and prolonging the service life. A fine chemical product with strong specialization and strong functionality. [0003] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer...
