Aerogel thermal-insulation decorative water-based paint as well as preparation method and application thereof

Abstract

The invention relates to an aerogel thermal-insulation decorative water-based paint which is composed of an aerogel multicolor paint dispersion phase, a granulation liquid and a transparent aerogel paint continuous phase, and the aerogel thermal-insulation decorative water-based paint is prepared through the steps of preparation of the aerogel multicolor paint dispersion phase, granulation, preparation of the transparent aerogel paint continuous phase, mixing and the like. The coating disclosed by the invention is green and environment-friendly, has decorative performance and heat-insulating and flame-retardant performance, can obtain a multifunctional coating through one-time construction, is suitable for reconstruction of existing buildings and interior and exterior walls of newly-built buildings, and has the advantages of being simple in preparation process, low in cost and high in practicability. The method has the technical effects of wide application range, good storage performance and the like.

Description

Technical field [0001] The invention relates to the field of chemical coatings, and in particular to an airgel thermal insulation decorative water-based coating and a preparation method thereof. Background technique [0002] At present, paints that produce toxic gases after domestic decoration are slowly being phased out. Water-based, latex and other architectural paints are commonly used. Although these paints have certain advantages such as water resistance, weather resistance and stain resistance, However, these coatings still have some problems, such as complex production processes and high prices; and some additives added during production will still release a certain amount of toxic gases, and the environmental performance needs to be improved. [0003] In our country, energy conservation of building exterior walls is still a top priority. Currently, the commonly used energy-saving methods are pasting insulation boards or using insulation mortar. Insulation boards are...

AI Technical Summary

Problems solved by technology

At present, the commonly used energy-saving methods are pasting insulation boards or using insulation mortar. Insulation boards are divided into organic insulation boards (EPS, XPS, etc.) and inorganic insulation boards (foam concrete, rock wool boards, etc.), and there are the following problems: 1. Insulation boards It is easy to fall off and threatens personal safety. 2. The organic insulation board is flammable and burns fast, which is easy to cause property loss and life danger. 3. The thermal conductivity of the inorganic insulation board is high, and water absorption affects the heat insulation performance and service life. 4. The thermal conductivity of the insulation mortar High coefficient, high thickness is required to meet energy saving requirements, and it is easy to crack and fall off when emptying

However, in this patent application, the mechanical properties need to be improved, and its decorative properties do not mention any advantages

Chinese patent publication CN113881300A discloses a thick airgel thermal insulation texture coating, but this technical solution is mainly dedicated to strengthening thermal insulation performance, and its decoration and practicability need to be improved
