Abstract

The invention discloses a lightweight energy-saving paint and its preparation method. The paint provided by the invention comprises the following components of: by weight, 45-55 parts of corundum hollow spheres, 20-30 parts of a lightweight filling material, 5-10 parts of fiber, 15-20 parts of a binder and 0-5 parts of an additive. The lightweight energy-saving paint prepared in the invention has characteristics of good fluidity, high strength, low thermal conductivity, strong adhesive force, high refractoriness, good chemical stability, strong corrosion resistance and the like, can be used for the surface coating of high temperature pipelines, thermal equipment and hearth inside and outside parts to effectively inhibit heat radiation and calorific loss, and can be used for spraying and coating the internal and external surfaces of various concrete structures and steel structure buildings so as to save energy, insulate sound and prevent fire.

Description

technical field [0001] The invention relates to a lightweight energy-saving paint and a preparation method thereof, belonging to the technical field of material science. Background technique [0002] Existing lightweight thermal insulation coatings are generally made of silicate materials such as asbestos, sepiolite, diatomite, aluminum silicate fiber, expanded perlite, etc., water is used as a dispersant, and a binder is added. The viscous slurry made by loosening and stirring can be applied to the working surface according to the specific situation when using it, so as to play the role of heat preservation and heat insulation. This type of coating has good stability, oxidation resistance, and radiation resistance. It can increase the fire resistance limit by increasing the coating thickness, but it has disadvantages such as poor adhesion and physical properties, large shrinkage, easy cracking and peeling, low strength, and low refractoriness. , the scope of use is limited...
