Transparent heat-insulation energy-saving nano paint and preparation method thereof

Abstract

The invention discloses a transparent heat-insulation energy-saving nano paint and a preparation method thereof, belonging to the field of functional paints. The paint is composed of a metal oxide inorganic nano water-based dispersion with optical thermal properties, a defoaming agent, a leveling agent and a diluter. The coated film formed by the paint has high reflecting power (higher than 80%) for thermal infrared rays with the wave range of 2.5-40 mu m; and therefore, the glass coated with the paint can act as a hot mirror to prevent outdoor heat radiation from entering the room so as to save the air conditioning cost in summer, and reflect most indoor heat radiation back to rooms in winter so as to ensure no indoor heat dissipation to the outside, thereby saving the heating cost.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a nano-material, which is a transparent heat-insulating and energy-saving nano-coating, which is mainly used in the fields of surface engineering science and surface engineering protection, especially when transparency, erosion (weather resistance, corrosion resistance) are required , wear resistance), heat insulation, energy saving, radiation shielding, low-carbon environmental protection and other environmental surface protective coating technology fields. Background technique [0002] Making glass both transparent and insulating has been a major topic in the field of surface engineering. The emergence of nanomaterials provides a new idea for solving the problem of transparent heat insulation. Nanoparticles are atomic groups or molecular groups that are composed of a limited number of atoms or molecules, maintain the original chemical properties of the substance and are in a metas...

AI Technical Summary

Problems solved by technology

The thermal infrared reflectivity of ordinary glass is only 11%.

Therefore, regardless of winter or summer, a single piece of ordinary glass cannot achieve the purpose of energy saving.
