The application of tire reclaimed rubber in the cloth cloth conveying hose

The cloth cloth hose is mainly used to transport water and other neutral liquids. Traditional cloth cloth hoses are mostly made of natural rubber and styrene butadiene rubber. In recent years, with the continuous advancement of domestic waste tire recycling projects, there are more and more tire reclaimed rubber on the market, and more recirculated rubber hoses have begun to use tire reclaimed rubber to reduce costs. So in actual production, how much tire reclaimed rubber can be used as the raw material of the cloth cloth hose? Is the amount of tire reclaimed rubber in the different parts of the cloth water delivery hose the same?

The cloth water conveying hose is mainly composed of inner layer rubber, rubbing rubber and outer rubber layer. Different parts have different performance requirements for rubber compounds.

1. The application of tire reclaimed rubber in the inner layer rubber of the cloth water transmission hose

The inner layer of the rubber hose is the first working surface of the hose. It directly contacts the conveying medium. Its main function is to support the pipe body and protect other parts of the hose. It has certain requirements for the medium resistance, hardness, stiffness and processing deformation of the rubber material. . The main purpose of the cloth cloth conveying hose is to transport water, and it does not have high requirements on the oil resistance and acid and alkali resistance of the rubber compound. When natural rubber and styrene-butadiene rubber are used as the main raw materials to prepare the inner layer of the water delivery hose, rubber product manufacturers can increase the amount of tire reclaimed rubber 2LLYY430 in an appropriate amount. In theory, 100 parts of raw rubber (the total amount of natural rubber and styrene-butadiene rubber) can be added About 100-150 parts of tire recycled rubber, the specific dosage is determined according to the actual performance requirements of the hose and the tire recycled rubber index.

2. The application of tire reclaimed rubber in the outer rubber of the cloth cloth water delivery hose

The outer layer of the rubber hose is the second working surface of the hose. Its role is to protect the skeleton material and the pipe body and directly contact with the external environment. It is generally resistant to the wear resistance, tear resistance and aging resistance of the rubber (such as (Light resistance, ozone resistance, weather resistance) and other performance requirements are higher, and rubber product manufacturers can use natural rubber / styrene-butadiene rubber / recycled rubber at a ratio of 1/1/1. In actual production, 100 parts of raw rubber (the total amount of natural rubber and styrene butadiene rubber) can be added to 40-60 parts of tire reclaimed rubber to reduce the production cost of the cloth water transmission hose.

3. The application of tire reclaimed rubber in the rubber layer of the cloth cloth water delivery hose

The cloth rubber hose wiper is a cloth layer glue connecting the skeleton layer and the inner and outer rubber layers. It has high requirements for the fluidity of the rubber compound, the permeability of the rubber compound to the fabric, the adhesion, the fatigue resistance and the tensile strength. When natural rubber and styrene-butadiene rubber are used as the main raw materials to prepare the cloth water transfer hose wiping layer, a certain proportion of tire reclaimed rubber can be added to prepare a water transport hose wiping good performance. In theory, 100 parts of raw rubber (the total amount of natural rubber and styrene butadiene rubber) can be added to about 20-50 parts of tire reclaimed rubber.

When using tire reclaimed rubber to reduce the production cost of water transmission hoses with different cloths, the amount of tire reclaimed rubber in different rubber layers is different, and the types and dosages of compounding agents are also different. I will share with you the layers of cloth rubber hoses containing tire reclaimed rubber Recipe design skills.
