Abstract

The invention relates to a method for preparing segmental type nano functional coating. It is characterized by that coating a multifunctional monodisperse nano complex film solution component A on coat surface of common coating component B by spraying or brush painting and curing to obtain it. The coating has nano functional particle high externalization and dispersion stability to overcome cladding and closing of pigment and film forming matter to nano particles for generally preparing nano composite coating so as to make nano material give full to excellent sterilizing and degrading organic matter, aging resistance, scrubbing resistance. Component A is composed of functional complementary nano TiO2,ZnO,SiO2 composite material(1.0-5.0%),film solution silicasol(5.0-10.0%),film forming additive polymer polyvinyl alcohol(500-1000ppm) and water, Ph 7.5-9.0.Component B is composed of resin base material, pigment, additives and water, Ph 8.5-9.5.The invention overcomes low utilization rate, hard dispersion and bad function of general nano material, and having high nano efficiency, and low cost.

Description

technical field

[0001] The invention belongs to the field of inorganic materials and nanometer technology, and relates to a manufacturing and construction method of a packaged nanocomposite functional paint. Background technique

[0002] At present, the general method of manufacturing nano-coatings can be divided into two categories: (1) nano-structured coatings. Nano-structured coatings are prepared by a special process to prepare nano-emulsions, which are prepared by mixing and mixing nano-polymer emulsions (base materials) with dispersed and stable nano-scale pigments and fillers, additives, etc. The cost of this type of coating is high, and there are still problems in the dispersion and stabilization of nano-pigment filler slurry at high concentrations. (2) Nano-composite functional coatings. Nano-composite functional coatings are made by adding nano-powder or its dispersion liquid as a functional component to ordinary pigment and filler slurry for high-speed sand grin...
