Embodiment 1

[0026]

[0027]

[0028] A and B are used in a ratio of 1.6:1.

[0029] The tested paint film properties are as follows.

[0030]

[0031] The comparison of the effects of different dosages of curing accelerators on the parameters of the intumescent carbon layer and the fire performance of the fire retardant coating is shown in the table below. The test conditions are that the flame temperature is 2000°F, the coating thickness is 1mm, and the fire test time is 15min. Except for the curing accelerator, the proportions of the raw materials are the same, as in Example 1.

Abstract

The invention relates to an environment-friendly epoxy intumescent fire-retardant coating and a preparing method thereof, and belongs to the field of functional coatings. The environment-friendly epoxy intumescent fire-retardant coating is prepared from a component A and a component B, wherein the component A uses epoxy resin as a main film forming matter and is added with a reactive diluent, a catalyst, a carbon-forming agent, a foaming agent, fire retardant, auxiliaries and solvent, and the component B is composed of a curing agent, a curing accelerator, pigment filler, auxiliaries, refractory fibers and solvent. In the component A, the ratio of the epoxy resin to the reactive diluent is 1:1-5:1. In the component B, the ratio of the curing agent to the curing accelerator is 1:1-5:1, and the usage quantity of the refractory fibers accounts for 5-50% of the total mass. The environment-friendly epoxy intumescent fire-retardant coating is free of alkylphenol, or halogen compounds, or boron compounds or sulfocompounds. The prepared environment-friendly epoxy intumescent fire-retardant coating is good in acid resistance, alkali resistance, water resistance, ageing resistance and salt mist resistance and is particularly suitable for fire-retardant protection for maritime and severe outdoor environments, the petrochemical industry and places with hydrocarbon fire potential hazards.

Description

technical field [0001] The environment-friendly epoxy intumescent fireproof coating prepared by the invention does not contain alkylphenol, halogen-containing compound, boron-containing compound and sulfur-containing compound. The environment-friendly intumescent fire-retardant coating prepared by the invention has excellent acid resistance, alkali resistance, water resistance, aging resistance and salt spray resistance, and is especially suitable for marine and harsh outdoor environments, petrochemical industry, hydrocarbon fire and explosion Potentially hazardous fire protection. Background technique [0002] Intumescent fire retardant coatings have been widely used in the fire protection of steel structure buildings due to their high expansion coefficient, strong flame retardant properties, good heat insulation, and low cost. The main components of intumescent fire retardant coatings include matrix resin, intumescent flame retardant system, pigments, fillers, additives a...
