Technical Field
The invention relates to the field of pipe fitting manufacturing, in particular to a composite heat-insulation water pipe.
Background
In daily life, water pipes play an important role in life as water supply appliances. Water pipe water supply systems are widely used in the fields of building life and the like, however, water pipes in the prior art are poor in heat insulation performance, and the water pipes are extremely easy to freeze in cold weather in winter, so that water consumption of residents is inconvenient. More importantly, in the heating system, because the water pipe has no heat preservation function, heat is greatly lost from the water pipe in the heating process, and the resource is greatly wasted.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide a composite heat-insulation water pipe.
The technical scheme adopted by the invention is as follows: a composite heat-preservation water pipe comprises a metal thin pipe, wherein a composite heat-preservation layer is coated outside the metal thin pipe.
Preferably, the thin metal pipe is made of 304 stainless steel, 316L stainless steel or 317L stainless steel; the thickness of the metal thin tube is not more than 1 mm.
Furthermore, the composite heat-insulating layer is of a multilayer structure and is formed by superposing 5-10 layers of aerogel felt composite fibers.
Preferably, the aerogel felt composite fiber is formed by thermally compounding aerogel composite powder, hot melt adhesive and base material fiber;
the aerogel composite powder comprises silicon dioxide aerogel, expanded perlite, a nano-pore metal organic compound, foamed high polymer resin, foamed phenolic resin and activated carbon;
the substrate fibers include carbon fibers, polyester fibers, spandex, polypropylene, nylon, and polyethylene.
Furthermore, the outer side of the composite heat-insulating layer is also provided with a rubber protective layer.
According to the composite heat-insulation water pipe, the multilayer aerogel composite felt fibers are compounded on the outer side of the thin metal pipe, so that the water pipe has excellent heat insulation performance and better mechanical strength, the thermal conductivity coefficient is lower than 0.015W/m.K, and meanwhile, the weight of the water pipe is reduced by more than 80%.
