Abstract

The invention discloses an intumescent fireproof paint and a preparation method thereof. The paint is composed of an emulsion, an intumescent flame retardant, a polymer additive, an aid, water and the like. By scientific material selection and reasonable collocation, a water-based vinyl acetate-ethylene copolymer emulsion used as a matrix is mixed and matched with multiple intumescent flame-retardant substances and high-molecular polymers, so that the paint film has favorable water resistance and high adhesive force. The carbon layer formed by heating the fireproof paint has the advantages of favorable adhesion property with the substrate, high strength, high expansion ratio and favorable continuous fire resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an intumescent fireproof coating and a preparation method thereof. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. [0003] Water-based fire retardant coatings mainly use polymer emulsion as the base material. On the one hand, the polymer must have a strong bonding effect, which can bind various components in the coating together. After drying, the fire retardant coating can form a strong coating. It has an important impact on the performance of the coating; on the other hand, when the coating is exposed to fire, as a polymer material, it is different from small molecules when it decomposes and carbonizes. Its carbonization strength is much higher. Therefore,...
