Thermal insulation coating and preparation method thereof

Abstract

The invention relates to a thermal insulation coating and a preparation method thereof, and the preparation method comprises the following steps: adding hollow granular micro-bubbles made of special materials, hollow glass beads and an opaque polymer on the basis of a water base, a bonding agent base material and a filler, combining active hydroxyl genes thereof with a molecular chain of an emulsion polymer and forming a dense net layer structure in a coating, wherein the coating has the comprehensive thermal insulation function of reflecting, blocking and radiating solar heat and has the significant effects of thermal insulation and energy conservation. The coating has strong adhesion to the surface of a building, the thickness of a coating dry film is only 60 mu m-150 mu m, and the coating is not only thermal-insulating, but also water-proof. The coating has excellent air permeability and long-lasting antibacterial property, as well as the advantages of pollution prevention, self-cleaning, sound isolation, aging resistance, long service life, easy construction and manpower conservation; compared with the traditional thermal insulation material, the coating has excellent performance-price ratio.

Description

technical field [0001] The invention relates to a heat-insulating paint and a preparation method thereof, which is a compound heat-insulating thin-coat type heat-insulating, heat-preserving, waterproof, and energy-saving paint, and belongs to the technical field of paint industry. Background technique [0002] Because of its good thermal insulation performance and simple construction process, thermal insulation coatings are playing an increasingly important role in modern industry and production. Coating thermal insulation coatings on the surface of buildings can significantly reduce the indoor temperature and make people feel better in hot weather. There is a good working environment under the weather. Thermal insulation coatings can generally be divided into organic and inorganic types. Organic coatings contain triphenyl and acetone substances, and inorganic coatings often contain asbestos fiber substances. The above coatings Both contain organic or inorganic substances th...

AI Technical Summary

Problems solved by technology

At present, heat insulation coatings on the market can be divided into three types: reflection type, barrier type and radiation type according to the heat insulation mechanism. Generally, a single heat insulation mechanism is used, which has weak reflection and low scattering of sunlight, and the heat insulation effect is not obvious. less energy saving

Moreover, the coating thickness of this type of coating is relatively thick, generally 0.3-2.0 mm, and the amount of coating per unit area is large, which makes it difficult to achieve the purpose of ensuring thermal insulation effect, environmental protection and energy saving
