Preparation technology of flexible butyronitrile double sided adhesive tape fire hose

Abstract

The invention discloses a preparation technology of a flexible butyronitrile double sided adhesive tape fire hose. NBR / PVC7030 is adopted as a main adhesive and molten with other ingredients by adopting changing temperatures, the flexible butyronitrile double sided adhesive tape fire hose is small in density, soft in touch, good in elasticity, high in strength, bright in surface, excellent in weather and aging resistance, fire retardant, capable of meeting the fire protection requirement, safe and reliable, and the flexible butyronitrile double sided adhesive tape fire hose has the extending and bending strength resisting quality, can bear tearing and rough force transmission, will not be damaged under the acute condition, an inner layer rubber pipe and an outer layer rubber pipe are subjected to high-temperature high-pressure press-fit with a reinforcing layer, tape turning is performed on time in the middle, the rubber pipes are subjected to a chemical reaction and physical absorption with the reinforcing layer through a white system, compact combination is achieved, the produced double sided adhesive tape is high in integrity, good in deflection resistance and long in service life, the water hose is flat, soft, low in weight, easy to unfold and fold and capable of effectively lowering labor intensity of users and improving the using comfort, and due to the covering layer is provided with corrugations, the fire hose is resistant to corrosion, capable of achieving heat preservation, good in corrosion resistance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting hoses, and in particular relates to a preparation process of a flexible nitrile double-sided adhesive fire-fighting hose. Background technique [0002] The fire hose is a tubular belt fabric that can withstand a certain liquid pressure. It can transport water, oil, foam fire extinguishing fluid, etc. under relatively high pressure. Drainage, etc. During the use of the fire hose, the user needs to lay, hold, move, rewind, etc. The existing nitrile rubber double-sided adhesive fire hose has a covering layer, a reinforcement layer, and an inner lining layer. Make the reinforcement layer in the middle, and then press into the covering layer and the inner lining layer. The inner lining layer is the innermost layer. During use, the labor intensity of the user will be increased, which will seriously affect the user experience, and the use time will be short and the cost will increase. Contents o...
