Problems solved by technology

[0002] At present, most of the FRP pipes on the market are non-flame retardant. Some manufacturers add appropriate inorganic fillers as flame retardants to the base material, which can achieve a certain degree of flame retardancy, but the fire resistance is poor and the effect is not ideal.
The existing FRP pipes can achieve a certain degree of flame retardancy after adding fillers to the base material. However, due to the increased brittleness of the material itself after the addition of fillers, the fire resistance is poor. After the surface is burned, the inner FRP structure layer is damaged, and the pipe body is severely Ineffective, let alone meet the fire-resistant and flame-retardant requirements of marine engineering

Embodiment 1

[0015] A new type of fire-resistant composite material pipe, including a glass fiber reinforced plastic pipe layer and a fire-resistant insulation layer arranged outside the fiberglass pipe layer. Methylenetetramine C6H12N4; after stirring evenly, then impregnate the fiber and wind it to the surface of the formed FRP pipe to solidify and form.

Embodiment 2

[0017] A new type of fire-resistant composite material pipe, including a fiberglass pipe layer and a fire-resistant insulation layer arranged outside the fiberglass pipe layer. The fire-resistant insulation layer is made of GP-486G34 phenolic resin as a matrix material, and 15% of six Methylenetetramine C6H12N4; after stirring evenly, then impregnate the fiber and wind it to the surface of the formed FRP pipe to solidify and form.

Embodiment 3

[0019] A new type of fire-resistant composite material pipe, including a fiberglass pipe layer and a fire-resistant insulation layer arranged outside the fiberglass pipe layer. The fire-resistant insulation layer is made of GP-486G34 phenolic resin as a matrix material, and 10% of six Methylenetetramine C6H12N4; after stirring evenly, then impregnate the fiber and wind it to the surface of the formed FRP pipe to solidify and form.

Abstract

The invention discloses a fireproof pipeline made from a new composite material. The fireproof pipeline is characterized by comprising an FRP (Fiber Reinforced Plastic) pipe layer and a fireproof insulating layer arranged at the outer part of the FRP pipe layer, wherein the fireproof insulating layer is made from GP-486G34 phenolic resin as a substrate material, 8-15% of hexamethylenetetramine CGH12N4 is added into the resin matrix material; soaked fibers are twisted on the surface of the a formed FRP pipe to solidify and form after the uniformly mixing. According to the fireproof pipeline provided by the invention, the flame retardant efficiency and the performance parameters of the product can be greatly improved, and the brittleness of the FRP pipe cannot be affected completely when the flame retardant efficiency is improved, therefore the code requirements of the IMO (International Maritime Organization) ISO753. (18) can be completely met, and the excellent fireproof products can be provided to a ship industry.

Description

technical field [0001] The invention discloses a fireproof pipeline, and in particular relates to a novel composite material fireproof pipeline. Background technique [0002] At present, most of the FRP pipes on the market are non-flame retardant. Some manufacturers add appropriate inorganic fillers as flame retardants to the base material, which can achieve a certain degree of flame retardancy, but the fire resistance is poor and the effect is not ideal. The existing FRP pipes can achieve a certain degree of flame retardancy after adding fillers to the base material. However, due to the increased brittleness of the material itself after the addition of fillers, the fire resistance is poor. After the surface is burned, the inner FRP structure layer is damaged, and the pipe body is severely Ineffective, let alone meet the fire-resistant and flame-retardant requirements of marine engineering.
