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

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...
