In the finish paint, the hydroxyethyl cellulose thickener is associated with the surrounding water molecules through hydrogen bonds through the main chain of the hydroxyethyl cellulose thickener to form a net structure in the mixed material, so that the free movement space of particles in the mixture is reduced, and the viscosity of the mixture is improved. When the coating added with the cellulose thickener is used, a hydration layer formed by the thickener and water is easy to damage in the coating process, so that the viscosity of the coating is quickly recovered, the coating is gelatinized, and the leveling operation of the coating is not facilitated.
The modified alkali solution thickener is alkali swelling acrylic emulsion which needs an alkaline environment to dissociate carboxylate radicals of the alkali swelling acrylic emulsion, alkaline film-forming aid AMP-95 is added in the invention, and the alkalinity of the film-forming aid dissociates carboxylate radicals in molecules of the film-forming aid, so that molecular chains are stretched from a spiral shape to a rod shape through the same-polarity electrostatic repulsion among carboxylate ions, the hydrogen bond association of the molecular chains and water molecules is increased, the viscosity of a water phase is improved, and meanwhile, the long-time water concentration of the composite finish paint after coating is ensured.

The free sepiolite powder is taken as a thickening agent and is filled into a frame formed by vermiculite, expanded perlite and vitrified micro-beads, and after the sepiolite powder fills gaps, fibers with the length of 4-8mm on the surface can stably fix the sepiolite powder in the gaps, so that the gaps of the composite material are reduced, the convection heat conduction of the composite material is reduced, and the heat reflection performance of the composite material is improved.
The vermiculite has a unique lamellar structure, the specific scales on the particle surfaces can perform heat reflection radiation, the effect of the asbestos wool in the composite material is greatly related to the proportion of the asbestos wool in the composite material, when the content of the asbestos wool is low, the asbestos wool cannot play a role of a supporting framework, when the content of the asbestos wool is high, the asbestos wool is mutually overlapped, so that the composite material conducts heat through a solid phase, and the heat conductivity of the composite coating is obviously improved, the volume content of the asbestos wool in the middle layer coating is about 10%, and the asbestos wool with the volume proportion not only enhances the strength of the composite coating frame, but also cannot cause the heat conductivity of the composite material to be improved due to overhigh content of the asbestos wool. The diameter of the selected asbestos wool is 0.1-30 μm, and the fiber of the asbestos wool is more than 0.5cm and less than 10 cm.

λ1∝(1-ε)λs
wherein λ1The thermal conductivity of the material is shown as the formula, wherein epsilon is the volume fraction of a gas phase, and lambdas is the thermal conductivity of a solid phase, the thermal conductivity of the material and the porosity of the material are in a linear decreasing relation, and the higher the porosity is, the smaller the thermal conductivity is, and the better the thermal insulation effect of the material is; on the contrary, the lower the porosity, the higher the thermal conductivity, and the poorer the heat preservation effect of the material.
The components of the expanded perlite mainly comprise SiO2, Al2O3, Fe2O3, CaO, K2O and Na2O, phosphate radicals in the aluminum dihydrogen tripolyphosphate monomer are phosphorus-oxygen tetrahedrons, wherein the phosphate radicals and the phosphate radicals are bridged with metal ions in mixed expanded perlite, vermiculite and the like to form long-chain or reticular high-molecular polymers, free movement spaces of particles in the mixture are reduced, suspended particles in the mixture are confined in a reticular structure, and therefore the aluminum dihydrogen tripolyphosphate has the characteristics of large binding power and high strength, and the viscosity of the mixture in the coating can be improved.
