Embodiment

[0042] EXAMPLES The preparation method of the elastic fire-proof airgel coating: add acrylic modified elastic polyester, distilled water, and wetting agent in sequence into a fixed cylinder, and stir evenly at a low speed. Slowly add melamine phosphate and airgel under stirring, and disperse at high speed for 30 minutes. Add chlorinated paraffin and stir well. Add thickener to adjust viscosity. Stand still for 4 hours, filter and pack with 200 mesh.

Abstract

The invention provides an elastic fireproof coating which comprises the following components in percentage by weight: 70-80% of acrylic acid modified elastic polyester; 15%-20% of melamine phosphate;5%-10% of a flame retardant; water or the like. Acrylic acid modified elastic polyester is selected as matrix resin of the coating, and the flame retardant, the wetting agent and the thickening agentare compounded so that the coating has excellent elasticity and flame retardance. The acrylic acid modified elastic polyester serves as the coating matrix of the water-based environment-friendly coating, the formula, the process are simplified and great environment-friendly value is achieved.

Description

technical field [0001] The invention relates to the technical field of polymer coatings, in particular to an elastic fireproof coating and its preparation method and application. Background technique [0002] Airgel is a highly dispersed solid material in which colloidal particles of silica aggregate to form a nanoporous network structure, and the pores are filled with a gaseous dispersion medium. The pore size of the airgel is close to or even lower than the mean free path of air molecules under normal pressure, so the air molecules in the pores of the airgel are approximately static, which avoids the convective heat transfer of the air, and the curved paths of the pores and the network structure The gaseous heat conduction of the air and the solid heat conduction of the gel skeleton are respectively prevented, and the heat radiation can also be blocked by doping the infrared absorber. However, the particle size of airgel particles is less than 10um, with small particle si...
