Novel water-based nano thermal insulation coating and preparation method thereof

Abstract

The invention provides a novel water-based nano thermal insulation coating and a preparation method thereof, and relates to the technical field of preparation of thermal insulation coatings. The invention discloses a novel water-based nano thermal insulation coating. The coating is prepared from the following raw materials in parts by weight: 10-20 parts of deionized water, 30-40 parts of acrylicweather-proof emulsion, 8-12 parts of near-infrared reflecting material, 10-20 parts of nanoscale hollow glass beads, 10-20 parts of composite nano ceramic beads, 3-5 parts of SiO2 aerogel, 5-10 partsof nano superfine fibers, 5-10 parts of nano titanium dioxide, 1-2 parts of coalescing agent, 0.5-1 part of ultraviolet light absorber and 5-8 parts of other auxiliaries. The prepared coating has theexcellent characteristics of low heat conductivity coefficient, good heat preservation effect and the like; and the purposes of saving energy, protecting the environment, saving labor and materials,reducing the cost, facilitating construction, shortening the construction period and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation coating preparation, in particular to a novel water-based nano thermal insulation coating and a preparation method thereof. Background technique [0002] 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.

[0003] With people's continuous pursuit of life, yearning for high-quality life, and the energy-saving and emission-reduction policies advocated by the country, it is often necessary to use thermal insulation coatings to transform existing building exterior walls or roofs and other areas that require thermal insulation. The exterior wall has the functions of heat preservation, heat insulation and weather resistance, but the existing thermal insulation coatings have poor heat preservation, heat insulation and weather resistance effects; Requirements for thermal insulation and energy-saving renovation
