Problems solved by technology

[0006] The three kinds of heat insulation materials have their own advantages and disadvantages. Although the insulating conductive heat insulation coating has certain limitations in performance, it is relatively low in cost and widely used; while the reflective and radiation type heat insulation The thermal effect is good, but the cost is high; therefore, there is an urgent need for a thermal insulation coating with high cost performance and good thermal insulation effect

Abstract

The invention belongs to the technical field of heat insulation coatings, and concretely relates to a heat insulation material for interior and exterior walls, and a preparation method thereof. A nano-slurry is innovatively added to a heat insulation coating based on the prior art, the nano-slurry adopts a silica nano-slurry, the silica has a good film-forming property and a low heat conductivity,and can assist heat conduction obstruction, and the nano-slurry has a good adhesion and a good viscosity, so the heat insulation material for interior and exterior walls has the advantages of easiness in dyeing and decorating and good heat insulation effect when applied indoors.

Description

technical field [0001] The invention belongs to the technical field of heat-insulating coatings, and in particular relates to a heat-insulating material that can be used for interior and exterior walls and a preparation method thereof. Background technique [0002] "Heat insulation coating": refers to a functional water-based coating developed in recent years that blocks, reflects, and radiates near-infrared heat from sunlight, which can insulate and cool roofs, save energy and reduce consumption. It has the characteristics of heat insulation, waterproof, anti-rust, anti-corrosion, short construction period, and quick results. It completely replaces the water spray system, thermal insulation cotton, foam sponge, interlayer iron sheet, etc. There are three main classifications of thermal insulation coatings in terms of characteristics and principles, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coat...
