Heat-resistant water hose and preparation method thereof

Abstract

The invention discloses a heat-resistant water hose, which comprises a lining layer, a reinforcing layer, a bonding layer, a thermal insulation layer and a protective layer, and is characterized in that the lining layer and the bonding layer are formed by blending and vulcanizing nitrile butadiene rubber and nylon, the reinforcing layer is made of synthetic fibers, the thermal insulation layer isformed by winding white carbon black type aerogel cloth by a winding machine, and the protective layer is made of PE, PA, TPU or PVC materials. According to the invention, a hose structure is changed,and a thermal insulation layer and a protective layer are added, so that heat preservation effect is achieved, and the protective layer can play a waterproof role, prevent water vapor from permeatinginto the thermal insulation layer to influence the thermal insulation effect and play a role in resisting abrasion and ageing; nylon and nitrile butadiene rubber are combined together, so that the heat resistance of the nitrile butadiene rubber is improved, the flexibility of the nylon is improved, and the service life is prolonged; and the product has multiple purposes, and oil, water and othermedia and gas can be conveyed.

Description

technical field [0001] The invention relates to the technical field of central heating, cooling, hot oil transportation and heat preservation and cold preservation in industries such as warm rooms, cold storages, coal mines, petroleum, and chemical industries, and specifically relates to a heat-resistant belt and a preparation method thereof. Background technique [0002] At present, the pipelines that transport heat medium are generally metal pipelines. The metal pipelines are coated with corrosion-resistant protective layer or heat-resistant polyethylene, cross-linked polyethylene. Severe corrosion will occur and life will be short. Heat-resistant polyethylene and cross-linked polyethylene are easy to crack because of their high hardness, and the service temperature generally does not exceed 80 degrees, and the service life when transporting heat medium is also greatly reduced. The product does not have the function of heat preservation and protection. In the prior art, i...

[0002] At present, the pipelines that transport heat medium are generally metal pipelines. The metal pipelines are coated with corrosion-resistant protective layer or heat-resistant polyethylene, cross-linked polyethylene. Severe corrosion occurs and short life

Heat-resistant polyethylene and cross-linked polyethylene are easy to crack because of their high hardness, and the service temperature generally does not exceed 80 degrees, and the service life when transporting heat medium is also greatly reduced

The product does not have the function of heat preservation and protection. In the existing technology, it is only possible to cover a layer of heat preservation material on the outside of the hose, but it can only be operated during the process of laying the pipe. The workload is heavy and the construction is more cumbersome and complicated.
