Abstract

The invention discloses a fly-ash-base geopolymer fire-retardant paint and a preparation method thereof. The fly-ash-base geopolymer fire-retardant paint comprises the following components in parts by weight: 30-40 parts of alkali excitant, 40-50 parts of fly ash, 0-15 parts of metakaolin, 0.02-0.04 part of dispersing agent, 0.03-0.05 part of defoaming agent, 10-20 parts of light calcium carbonate powder, 0.5-0.8 part of flame retardant, 0.02-0.04 part of thickener, 1.0-1.5 parts of polymer emulsion and 10-20 parts of water. The fly-ash-base geopolymer fire-retardant paint solves the technical problems in the traditional fire-retardant paint for steel structures, has the advantages of simple preparation technique, high durability, low cracking and shedding tendency, environment friendliness, no toxicity and high drying rate, and can be used for inside and outside protection of steel structure buildings. The fly-ash-base geopolymer fire-retardant paint effectively utilizes the fly ash, phosphogypsum and other industrial waste resources as the filler, thereby lowering the cost, and reducing the environmental damage caused by exploitation and use of other mineral fillers.

Description

technical field [0001] The invention belongs to the technical field of fireproof materials, and relates to a fly ash base polymer fireproof coating and a preparation method thereof. Background technique [0002] As a new type of building structure in recent years, steel structure has the advantages of flexible structure, light weight, high strength, good shock resistance and deformation, short construction period, easy maintenance, etc., and has been widely used in construction. Although the steel structure itself is a non-combustible material, it has the fatal weakness of poor fire resistance. Under the high temperature of fire, its mechanical properties such as yield strength, elastic modulus, and load capacity will decrease with the increase of temperature. When the temperature of the structure reaches 300-400°C, its strength will drop by 50%, and when the temperature reaches 600°C, the steel structure basically loses all its strength and stiffness. The temperature of a...
