The invention discloses exterior wall coating composed of the following raw materials in parts by weight: 70-80 parts of aqueous acrylic emulsion, 20-30 parts of styrene-acrylic emulsion, 10-20 parts of nano calcium carbonate, 14-20 parts of nano aluminium silicate, 13-20 parts of nano titanium dioxide, 2-3 parts of nano zinc oxide, 2-3 parts of butyl acrylate, 2-4 parts of pentaerythritol, 0.5-1 part of ethoxylated alkyl phenol ammonium sulfate, 1-2 parts of penta-chromium triboride, 0.6-1 part of sodium persulfate, 0.8-1 part of propyl trimethoxy silane, 0.1-0.2 part of tributyl phosphate, 3-5 parts of coalescing agent and 10-20 parts of deionized water. The coating produced by the invention is small in raw material loss, small in gel generation, simple in process, firm in paint film, good in glossiness, strong in impact resistance, unlikely to crack, soft in texture, good in decoration, high in weather resistance and scrub resistance, strong in adhesive force, long in service life, free of special smell, free of such heavy metals as mercury and lead and free of formaldehyde volatile, thereby meeting the technical demands of environmentally-friendly coating, and the added coalescing agent has high stability and high adhesion efficiency and film-forming property, increases the density of the coating film and perfects the film forming quality, so that the film layer has the advantages of strong adhesive force, non-cavity or cracking and good density and uniformity, and the like.

Description

A kind of nano multifunctional outer wall coating and preparation method thereof
Technical field
The present invention relates generally to a kind of coating, relates in particular to a kind of nano multifunctional outer wall coating and preparation method thereof.
Background technology
In recent years; along with the raising of living standards of the people and the development of society; people are to the selection pay attention to day by day of building decoration coating, and are more simple better to the construction requirement of coating, for particularly in exterior coating; not only rest in the most basic protection to ground; decorative effect to coating is had higher requirement, and exterior coating requires to have water repelling property, requires to have from washing property; it is hard and smooth, dirty once rushing that paint film is wanted.
But the acrylic coating of throwing on the domestic market exists, and gloss is low, poor adhesive force, winter hardiness are poor, not water-fast, water vapour, soda acid, salts solution and organic polar solvent, poor flexibility under the room temperature, the shortcoming such as wear no resistance, and high temperature easily returns sticking, fragile under low temperature splitting, cause coating to ftracture easily, peel off, rainwater etc. infiltrate metope, corrosion body of wall easily, and this not only affects the beautiful decoration of buildings, and will reduce the work-ing life of buildings.
Summary of the invention
The object of the invention is exactly in order to remedy the defective of prior art, exterior coating that a kind of paint film is stable, glossiness is good, tolerance is strong and preparation method thereof to be provided.
The present invention is achieved by the following technical solutions:
