Problems solved by technology

[0003] The material of the pipes in the prior art is mostly iron or plastic parts, and its flame retardant effect is poor. Once the pipes are exposed to fire, the pipes are easy to be burned
In addition, the commonly used pipelines are single-layer structures, if they are partially damaged, they can only be replaced as a whole

Abstract

The invention discloses a green, environmentally-friendly and flame-retardant double-layer pipeline. The double-layer pipeline comprises an inner layer pipeline and an outer layer pipeline, the innerlayer pipeline is coaxially arranged in the cavity of the outer layer pipeline; the outer wall of the outer layer pipeline is coated with a flame-retardant coating layer; a flame-retardant coating isprepared from, by mass, 20-35 parts of aqueous polyurethane, 17-42 parts of an aqueous acrylic resin emulsion, 3-6 parts of sodium silicate, 2-4 parts of ammonium polyphosphate, 2-4 parts of sulfosuccinate, 0.5-2 parts of a silane antifoaming agent and 70-90 parts of deionized water; and a clamping groove is arranged in the end part of the outer layer pipeline, and the end part of the inner layerpipeline is provided with a projection matched with the clamping groove. The double-layer pipeline has the advantages of good flame retardation effect and detachability.

Description

technical field [0001] The invention relates to the technical field of environment-friendly materials, in particular to a green and environment-friendly flame-retardant double-layer pipeline. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] The material of the pipelines in the prior art is mostly iron or plastic parts, and its flame retardant effect is relatively poor. Once the pipeline is exposed to fire, t...
