Embodiment 1

[0020] A fire hose, as shown in Figure 1, includes a rubber-plastic tube 3 made of rubber-plastic material, a cylindrical skeleton 1 made of fibers woven on the outer layer of the rubber-plastic tube 3, the outer wall of the rubber-plastic tube 3 and fiber The coating 2 between the braided tubular framework 1 is coated on the outer wall of the rubber-plastic tube 3, and the coating 2 is an adhesive for bonding the outer wall of the rubber-plastic tube 3 and the tubular framework 1 into a whole.

Embodiment 2

[0022] The raw material ratio of rubber-plastic pipe in embodiment 1 is as follows by weight:

[0023] 52 parts of polyvinyl chloride 1.1 parts of cadmium stearate

[0024] 3.2 parts of nitrile rubber, 65 parts of dioctyl oil

[0025] 1.1 parts of calcium zinc stearate 6 parts of light calcium carbonate powder

Abstract

A kind of fire control water band it includes a rubber plastic pipe, a tubular skeleton and a coat; the manufacturing method of fire control water band is that: a. the longitude and the latitude line interlace to form the tubular skeleton; b. mix the material of making the rubber plastic pipe as following: polyvinyl chloride, stearic acid cadmium, butyl rubber, di-n-fatty oil, sterric acid calcium zinc, light calcium carbonate powder, barium stearate; c. heat the mixed rubber plastic pipe material then rack the heated rubber plastic pipe material into the rubber plastic pipe after that the rubber plastic pipe becomes coiling after cooling; d. make the coiling rubber plastic pipe gumming and the gumming layer at the outside wall of rubber plastic pipe is the coat and then make the rubber plastic pipe after gumming through into the tubular skeleton then curing it. At the time of curing first fill air into the rubber plastic pipe let the rubber plastic pipe coincidence with the tubular skeleton then fill water vapor into the rubber plastic pipe and then dry it at last pack it into production; the invention has low cost and high productive efficiency.

Description

technical field [0001] The invention relates to a fire hose and a manufacturing method thereof. Background technique [0002] In the prior art, the outer layer of the fire hose used for fire protection is currently commonly used polyester and polyester yarn or polypropylene yarn as the material to form a tubular skeleton. The rubber tube is made of natural rubber and requires a certain thickness and pressure resistance. , wear resistance, aging resistance and other properties. After long-term use, it is found that the product is heavy in weight per unit length of rubber, and it is inconvenient to use and operate. Because of the production process, the rubber tube is not firmly bonded to the edge of the cylindrical frame, and it is easy to break and seep water. Especially, the low temperature performance is poor. In the environment of minus 40°C, the rubber tube will harden and affect the use effect. The manufacturing method of this fire hose is ...
