Abstract

The invention discloses an expanded type fireproof coating and a preparation method thereof, which are characterized by comprising the steps of grinding and dispersing 15-35 percent of microcapsule flame retardants, 5-10 percent of fillers and 10-30 percent of solvent according to the percentage of the total mass of the coating after preparation until the fineness thereof is less than 90 microns;then adding and dispersing coating matrixes and additives which respectively take up 20-40 percent and 1-5 percent of the total mass of the coating after preparation until the system is uniform; and alternatively adding flame retardant synergist agents which account for 0-10 percent of the total mass of the coating after preparation before grinding. The obtained expanded type fireproof coating hasgood stability, overcomes the defects of poor high-temperature resistance, poor anti-aging performance, poor water resistance and the like in the traditional organic expanded type fireproof coating,lowers the use amount and cost of the flame-retardant additives which all realize non-halogenation, does not cause larger impact on the environment, and has very good application prospects.

Description

technical field [0001] The invention belongs to the technical field of intumescent fireproof coatings and preparation methods thereof, and in particular relates to a polymer, a microencapsulated charcoal catalyst, a microencapsulated charcoal agent, a microencapsulated foaming agent, a flame retardant synergist, a filler, an auxiliary agent and Solvent intumescent fireproof coating and preparation method thereof. Background technique [0002] At present, the intumescent fire retardant coating is mainly based on the P-C-N intumescent flame retardant system, which is mainly composed of three parts: a carbon-forming catalyst, a carbon-forming agent and a foaming agent. Carbon-forming catalyst refers to a kind of compound that can be decomposed by heat to produce acid with dehydration effect, and is a key component of the expansion system. The most commonly used carbon-forming catalyst is ammonium phosphate, such as ammonium phosphate, diammonium hydrogen phosphate, ammonium di...
