Abstract
Relating to the technical field of functional coatings, the invention aims to provide a flame retardant and heat preservation slurry. The flame retardant and heat preservation slurry is formed by mixing of the following raw materials by weight percentage: 20-40% of nano silica aerogel, 10-30% of nano alumina sol, 30-50% of deionized water, 4-17% of asbestos fiber and 0.3-3% of a dispersing agent. The flame retardant and heat preservation slurry provided by the invention can be used for preparing a coating structure with flame retardant and heat preservation functions. Tests show that the thermal conductivity of the coating can reach 0.15W/m.K and below, while the thermal conductivity of ordinary heat preservation coatings is about 0.3W/m.K; the adhesion can reach over the national standard grade 1; and the coating is non-flammable under high temperature. Therefore, the flame retardant and heat preservation functional coating structure provided by the invention has the characteristics of high thermal insulation and flame retardance. The raw material cost is low, the preparation process is simple, and the coating adhesion is good. The coating structure adopts conventional concrete slab or cement slab as the matrix, and is easy to realize large-scale industrial production.
