Abstract

The invention relates to an expanded vitreous micro-bead thermal insulation coating composite and the preparation method thereof and is characterized in that the main components include expanded vitreous micro-bead accounting for 8 to 11 percent, high silicon aluminum silicate wool accounting for 4 to 6 percent, brucite cashmere accounting for 5 to 10 percent, osmotic agent accounting for 0.5 to 2 percent, polyacrylamide accounting for 5 to 10 percent, casi powder accounting for 3 to 7 percent and the production method thereof. By adopting vitreous micro-bead as the main materials, the expanded vitreous micro-bead thermal insulation coating composite has the advantages of high stability, low dry density, low thermal conductivity, high application temperature, low cubical contraction and low comprehensive production cost, and is innoxious, harmless, taintless, environment-friendly and energy-saving material. The thermal insulation range of the coating composite of the invention is fromminus 80 DEG C to 1,100 DEG C.

Description

technical field [0001] The invention relates to the field of thermal insulation and energy-saving coatings for thermal pipelines and steam pipelines of industrial kiln equipment in the building materials industry, in particular to a thermal insulation coating of expanded vitrified microspheres and a production method thereof. technical background [0002] At present, the existing thermal insulation coating silicate composite thermal insulation coating and xonotlite thermal insulation coating are all thermal insulation coatings with perlite, expanded vermiculite, diatomite, and bentonite as fillers. Significantly, its component asbestos contains carcinogenic factors. Silicate coatings can only be used in industrial equipment below 700°C. Its thermal conductivity is in GB / T17371-1998, and the national standard excellent product is: ≤0.06W / (m.k) when the average temperature is 343K±5K. Slurry density≤1000kg / m 3 , The highest volume shrinkage rate is ≤30%, the main reason is t...
