Problems solved by technology

At present, there are many kinds of thermal insulation coatings commonly used in buildings. However, due to unreasonable formulas, they are prone to delamination with the surface mortar under strong sunlight for a long time, causing cold bridge heat loss at the joints of profiles, resulting in thermal insulation failure. Poor effect, short service life, poor ductility, easy to break, and easy to produce toxic gas at high temperature, its function is single, not waterproof, anti-corrosion, fire-proof

Abstract

The invention belongs to the technical field of thermal insulation materials and in particular relates to a sodium-based thermal insulation coating and a preparation method thereof. The sodium-based thermal insulation coating is prepared from the following components in parts by weight: 10-35 parts of perlite, 10-30 parts of aluminum silicate fiber, 10-30 parts of wood fiber, 2-10 parts of kaolin, 5-20 parts of pearlite sand, 5-15 parts of floating bead, 8-20 parts of brucite fiber, 5-20 parts of bentonite and 0.5-3 parts of water and is prepared by the steps of mixing, standing and the like. By virtue of adopting the thermal insulation coating prepared by the method, the fire resistance, the high temperature resistance, the flame retardancy, the corrosion resistance, the waterproofness and the performance cost ratio are high, the application range is wide, and therefore, the sodium-based thermal insulation coating has very high market value.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a nano-based thermal insulation coating and a preparation method thereof. Background technique [0002] Thermal insulation coating is a new type of thermal insulation material, a coating that achieves thermal insulation through low thermal conductivity and high thermal resistance. At present, there are many kinds of thermal insulation coatings commonly used in buildings. However, due to unreasonable formulas, they are prone to delamination with the surface mortar under strong sunlight for a long time, causing cold bridge heat loss at the joints of profiles, resulting in thermal insulation failure. The effect is poor, the service life is short, the ductility is poor, it is easy to break, and it is easy to generate toxic gas at high temperature. It has a single function and does not have the effects of waterproof, anti-corrosion, and fire prevention...
