Thermal insulation coating and preparation method thereof

Abstract

The invention discloses a thermal insulation coating and a preparation method thereof. The thermal insulation coating is prepared from the following components: 15-20% of water, 0.1-0.5% of an antifoaming agent, 0.1-0.5% of hydroxyethyl cellulose, 0.5-1.5% of an ammonia salt dispersing agent, 0.1-0.3% of a wetting agent, 0.5-2% of propylene glycol, 1-20% of rutile titanium dioxide, 5-10% of infrared reflection pigment, 3-8% of superfine hollow micro-spheres, 5-10% of superfine barium sulfate, 3-5% of mica powder, 25-45% of silicone acrylic emulsion, 1-5% of a polyurethane thickening agent and1-5% of a mildew-proof alga-resistant agent. The coating system integrates isolated conductive thermal insulation coatings, reflective thermal insulation coatings and radiative thermal insulation coatings into a whole, the thin coating construction area is large, the service life of the coating is 10 years or longer, any color can be blended, the decorative effect is good, and the thermal insulation coating can realize thermal insulation, has a certain fireproof function and can be used for decorating protective insulation and thermal insulation coating of roofs and building walls.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermal insulation coating and a preparation method thereof. Background technique [0002] Architectural coatings are generally used to paint walls. With the development and progress of society, energy and environmental protection issues have increasingly attracted people's attention. As an important aspect of saving energy and improving the function of buildings, the thermal insulation of buildings has also attracted increasing attention from the whole society. At present, building energy consumption such as air-conditioning and heating accounts for more than 30% of the total energy consumption of human beings. Coatings can greatly reduce the indoor temperature by coating the building surface, preventing heat transfer and achieving the function of thermal insulation. At present, the thermal insulation coatings used in the market are not resistant to stains, easy to absorb du...

AI Technical Summary

Problems solved by technology

At present, the thermal insulation coatings used in the market are not resistant to stains, easy to absorb dust, and need to be refurbished after a service life of 1-2 years; the number of construction times is large, and the color cannot be adjusted, or the imported color paste is expensive, and ordinary color matching The retroreflection performance cannot meet the energy-saving requirements, resulting in waste of resources. The development of high-quality architectural coatings has become an important issue in the development of the coatings industry.
