Problems solved by technology
This kind of hose can basically meet the requirements when it is used to transport fluids such as water, but if it is used to transport oil, etc., due to the high temperature caused by the friction between the transported fluid material and the polyurethane coating, it will cause accidents.
In addition, the polyurethane coating has poor oil resistance and cannot be used in other industries such as oil fields.

Embodiment Construction
[0012] 1. Production of tubular polyester woven fabric:
[0013] The polyester yarn is used as the machine-made warp yarn, the polyester yarn is used as the machine-made weft yarn, and the tubular polyester woven fabric is formed by machine weaving.
[0014] 2. Prepare the mixed coating of nitrile and PVC:
[0015] Weigh nitrile and PVC at a mixing and feeding ratio of 30-70% and 30-70%, respectively, preferably: 4kg of nitrile and 6kg of PVC, put them into the mixer, melt at high temperature, fully mix, keep warm, prevent solidification, and set aside.
[0016] 3. Production of heat-resistant and oil-resistant electrical hose belts:
[0017] 1. According to the required length of the pipe belt, cut the tubular polyester woven fabric to form a segment.
[0018] 2. Coat the outer surface of the section material with a mixed paint of nitrile and PVC, and let it dry naturally.
[0019] 3. Turn the inside and outside of the section material inside out.
[0020] 4. Roll up the ...

The invention provides a production method for a temperature-resistant and oil-resistant electric hose, and relates to the technical field of fluid delivery hose production. According to the production method, weaving is adopted to form a tubular terylene woven fabric, and the fabric is cut off to form a segment material; the outer surface of the segment material is coated with a mixing coating formed by mixing butyronitrile and PVC, and open-air drying is performed at a room temperature; and the segment material is turned inside-out. According to the present invention, terylene is adopted to replace original cotton as a woven fiber material, durability of the temperature-resistant and oil-resistant electric hose of the present invention is increased through the formed tubular terylene woven fabric, and the mixing coating formed by mixing butyronitrile and PVC is arranged on the inner surface so as to provide good oil resistance and good high temperature resistance, and effectively prevent accidents caused by high temperatures. In addition, the temperature-resistant and oil-resistant electric hose of the present invention has high safety, and is suitable for delivery of oil or special products in chemical industries.
Description
technical field [0001] The invention relates to the technical field of production of fluid conveying pipe belts. Background technique [0002] The common fire-fighting or irrigation water belts are mostly composed of cotton woven pipes. In order to avoid water leakage, the inside of the pipes is coated with polyurethane coating. This kind of hose can basically meet the requirements when it is used to transport fluids such as water, but if it is used to transport oil bodies, etc., accidents will occur due to the high temperature generated by the friction between the transported fluid material and the polyurethane coating. In addition, polyurethane coatings have poor oil resistance and cannot be used in other industries such as oil fields. Contents of the invention [0003] The purpose of the present invention is to propose a production method of an electric hose belt with better temperature and oil resistance. [0004] The present invention comprises the following steps: ...
