Super-weather-resistant infrared reflection heat-insulation inorganic coating and preparation method thereof

Abstract

The invention relates to a super-weather-resistant infrared reflection heat-insulation inorganic coating and a preparation method thereof. The super-weather-resistant infrared reflection heat-insulation inorganic coating is mainly prepared from the following components in parts by weight: 250-300 parts of water, 3-7 parts of a dispersing agent, 2-4 parts of a wetting agent, 2-4 parts of a defoaming agent, 3-7 parts of cellulose ether, 75-130 parts of infrared reflection pigment, 150-200 parts of wollastonite powder, 100-200 parts of barium sulfate, 75-125 parts of titanium dioxide, 5-10 partsof a freeze-thaw resistant stabilizer, 50-150 parts of organic modified potassium silicate, 50-100 parts of acrylic emulsion and 2-4 parts of an organic silicon defoaming agent. According to the invention, the defect that no inorganic coating with reflective heat-insulating property, fire resistance and weather resistance exists in the existing market is overcome, and a paint film is enabled to have excellent reflective heat-insulating property, fire resistance and weather resistance at the same time through the cooperation of the optimized acrylic emulsion and the optimized infrared reflective pigment.

Description

technical field [0001] The invention relates to a super-weather-resistant infrared reflective heat-insulating inorganic coating and a preparation method thereof, which are applied in the field of inorganic coating production. Background technique [0002] At present, there is no clear definition of inorganic coatings. According to the habit of naming coatings, they are generally classified according to the main film-forming substances. Therefore, inorganic coatings usually refer to a type of coatings that use inorganic materials as the main film-forming substances or binders. Common inorganic binders include cement, gypsum, alkali metal silicate (water glass), silica sol, lime, etc. Silicate Emulsion Paints are monolithic paints prepared with potassium silicate as the main binder, supplemented with organic emulsion base material (<5%), and added appropriate amount of inorganic pigments, fillers and various additives. One-component coatings have the characteristics of one...
