Problems solved by technology

However, intumescent flame retardant coatings still have unresolved problems and defects caused by their own material structure, mainly as follows: (1) the flame retardant performance needs to be further improved; (2) the water resistance is low, and when hardening shrinks It is easy to cause cracking of the coating film, and the moisture absorption rate is high; (3) The impact resistance is weak, the coating is brittle and inelastic, and has no ability to adapt to the expansion and contraction of the substrate and the opening and closing of cracks, etc.
At the same time, realizing the multifunctional development of flame retardant coatings has become an important development direction at present, such as conductive coatings, etc., but there are not many records about conductive flame retardant composite coatings

Abstract

The invention provides a preparation method of a polyester resin based conductive intumescent flame-retardant composite coating. The novel environment-friendly and low-cost multifunctional flame-retardant composite coating is prepared with polyester resin as aggregate, graphite as a reinforcing flame retardant and a conductive material, sodium silicate as a dispersant and polydimethylsiloxane as afilm forming agent and a modifier. The composite coating has excellent flame retardance and conductivity and contributes to functional development of flame-retardant coatings.

Description

technical field [0001] The invention belongs to the technical field of chemical building materials and fire safety, and in particular relates to a preparation method of a polyester resin-based conductive expansion type flame-retardant composite coating. Background technique [0002] Intumescent flame retardant coating (IFR) is the main trend to realize the halogen-free ecological development of flame retardant materials. When it burns, it forms a porous intumescent carbon layer, which has the functions of heat insulation, oxygen insulation, preventing volatile matter from escaping and oxygen diffusion. Thermal barrier effect, and the free radicals contained in the carbon layer can react with the gaseous free radicals formed by the thermal degradation of the mixture, terminate the free radical reaction chain of the thermal cracking of the polymer, and slow down the thermal degradation of the polymer protected by the carbon layer in the condensed phase . However, intumescent ...
