Problems solved by technology

Use traditional epoxy fire-resistant coatings on such substrates, and the fire-resistant coating is easy to crack and fall off
At the same time, after the dry film of traditional epoxy fireproof coatings, the internal stress of the coating is relatively large, and it is easy to separate from the substrate, so it is not suitable for the surface of amorphous substrates, such as oil storage tanks and oil pipelines in the petrochemical industry.

Embodiment 1

[0028]

[0029] A and B are used in a ratio of 2:1.

[0030] The performance of the test paint film is as follows.

[0031]

[0032] The impact of different additions of tougheners and synthetic elastomers on the parameters of the intumescent carbon layer of fire retardant coatings and the impact on fire performance are compared in the table below. The test conditions are that the flame temperature is 2000 ° F, the coating thickness is 1 mm, and the fire test time is 15 minutes. Except for the toughening agent and the synthetic elastomer, the dosage ratio of each raw material is consistent with that of Example 1.

Abstract

The invention relates to a flexible intumescence fire-retardant coating and a preparation method thereof, and belongs to the field of functional coatings. The flexible intumescence fire-retardant coating is composed of a component A and a component B. The component A is prepared from epoxy resin, reactive diluent, synthetic elastomer, flexibilizer, a catalyst, a carbon-forming agent, a foaming agent, fire retardant, auxiliaries and solvent. The component B is prepared from a curing agent, a curing accelerator, pigment filler, auxiliaries, refractory fibers and solvent. The flexible epoxy intumescence fire-retardant coating prepared through the method has certain flexibility, and is particularly suitable for fire-retardant protection of the surface of a flexibility or deformation base material and the surface of a shapeless base material or the surface of light metal. In addition, the flexible epoxy intumescence fire-retardant coating prepared through the method has excellent water resistance, medium resistance, ageing resistance and salt-fog resistance and is suitable for fire-retardant protection of hydrocarbon fire potential risk areas in the ship, airplane and ocean environment and the petrochemical industry.

Description

technical field [0001] The flexible epoxy intumescent fire-proof coating prepared by the present invention has certain flexibility, and is especially suitable for substrates with flexibility or deformation, surfaces of amorphous substrates, such as polyester fibers (glass fibers), various plastics, carbon fibers Composite materials, fiberglass, polyurethane foam, rubber, or fire protection for light metal surfaces (such as aluminum alloys, titanium alloys), oil storage tanks, and oil pipelines. In addition, the flexible epoxy intumescent fireproof coating prepared by the present invention has excellent water resistance, medium resistance, aging resistance, and salt spray resistance, and is suitable for ships, aircraft, marine environments, and petrochemical industries with hydrocarbon fire potential. Fire protection in hazardous areas. Background technique [0002] The intumescent fireproof coating of the two-component epoxy system has excellent sealing properties, acid res...
