Environment-friendly, acid-proof and high-temperature-resistant exterior wall coating material and preparation method thereof

Abstract

The invention provides an environment-friendly, acid-proof and high-temperature-resistant exterior wall coating material and a preparation method thereof. The coating material comprises the following components: organic silicon-modified epoxy resin, bisphenol-A epoxy resin, a thermal insulation filler, nano-silica, an anti-rusting pigment, carboxymethyl cellulose, acetone, nano-calcium carbonate, butyl acetate, a cosolvent, deionized water, dibutyl phthalate, a pH regulator, a dispersing agent, a film forming agent and a thickening agent. The bisphenol-A epoxy resin is matched with the organic silicon-modified epoxy resin, so that the coating material has good lustrousness and static electricity resistance and relatively good mechanical property, ageing resistance and chemical corrosion resistance; by adding the thermal insulation filler and the anti-rusting pigment, the high temperature resistance, the corrosion resistance and the acid resistance of the coating materials are effectively improved; furthermore, the coating material has the superiorities in price and environmental protection, is strong in adhesive force, good in ductility and long in service life and can resist high temperature; and a spray painting manner is replaced with a roller painting manner during the painting, so that the production environment is effectively improved, and the body health of workers is improved.

Description

technical field [0001] The invention relates to an environment-friendly acid-resistant and high-temperature-resistant architectural exterior wall paint and a preparation method thereof. Background technique [0002] Paint, traditionally known as paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a...

Problems solved by technology

The main problem in spraying is highly dispersed paint mist and volatilized solvents (i.e. volatile organic pollutants, VOCs), which not only pollute the environment, are not conducive to human health, but also waste paint and cause economic losses
