Industrial steel wire rubber hose is mainly used to transport liquids such as gas, water, oil, etc. It has excellent elasticity and compression resistance, and the application environment temperature is -40~+150°C. It can be widely used in construction, electric power, railway, bridge and other fields. Industrial steel wire rubber hoses can be divided into chemical fiber hoses and synthetic fiber hoses according to materials; according to structural characteristics, they can be divided into soft, medium and hard (including inner rubber layer and outer rubber layer); soft and hard; soft, medium and hard Full range of hard rubber. Soft rubber can be divided into natural rubber soft rubber and synthetic rubber soft rubber. The structure of industrial steel wire rubber hose is composed of outer rubber layer, metal skeleton material and hose itself. The inner rubber is an elastomer made of butyl rubber with silica as a synergist.

1. Application of butyl rubber hose

The main raw materials are butadiene and isobutylene, which are key raw materials for the production of various rubber products. (1) Butyl rubber is a high polymer compound, which is made by adding some additives that can produce cross-linking reaction with natural rubber and synthetic rubber during the mixing and refining process. (2) Butadiene can improve the elasticity, strength and aging resistance of vulcanized rubber, but the temperature resistance is weak. (3) Isobutylene cannot be vulcanized, and is generally mixed with other ingredients to meet the requirements of different standards. According to the inner rubber, outer rubber and filler used, its process performance can be divided into soft material and hard material. (4) Butyl rubber has good cold resistance, high elasticity for low-temperature molds, high heat resistance, and does not burn.

2. The inner rubber is a synthetic fiber material with white carbon black as a synergist

This kind of synthetic fiber is made of natural butyl rubber. It is a widely used new technology product with the following characteristics: 1) Excellent wear resistance: the wear resistance of synthetic fiber materials with white carbon black as synergist The abrasiveness is much higher than that of synthetic fiber materials with natural butyl rubber as synergist. 2) Better chemical resistance: Because silica is a better catalyst, butyl rubber can be converted into high polymer rubber and carbon fiber (polyester). 3) Excellent heat resistance: it will not dissolve at high temperature. 4) Excellent antistatic properties: it can not only improve the resistance of rubber materials to polarization, friction and radiation of various magnetic field elements (such as electromagnetic waves, ultraviolet light, etc.). ), but also make synthetic fibers (such as polyester) and butyl rubber or other synthetic fibers to establish good heat resistance. 5) Excellent aging resistance: Because silica has a good reinforcing effect on rubber and synthetic fibers, it is widely used, especially in outdoor places. 6) Excellent impact toughness: its strength is higher than that of natural butyl rubber and synthetic fibers.

3. The outer viscose is made of chemical fiber material.

Chemical fiber materials include cotton fibers, etc. Because the chemical fiber material has good elasticity and high strength, natural wool and industrial steel wire rubber hose can be used for natural and synthetic rubber. (1) Synthetic fibers: including various polyester and polyolefin resins. (2) Synthetic rubber: including the main products of polysulfide rubber, polyamide rubber and spandex. (3) Natural rubber: Contains filaments and short fibers, which can be used in the production of short fiber hoses. (4) Man-made synthetic rubber: chlorinated polyethylene, polypropylene, polyester main products and mixed rubber materials of natural rubber.
