The ethylene propylene diene monomer used for preparing the water delivery hose has good tensile strength, good elongation at break and rebound resilience and can bear heavy loads and resist flex cracking.
Description
Technical field
The invention belongs to polymeric material field, and in particular to a kind of ethylene propylene diene rubber for preparing delivery hose.
Technical background
Rubber hose, refers to wire braided hose, and it is typically made up of inner glue layer, layer of steel wire braiding layer and outer glue-line.
Suitable for delivering hydraulic fluid, such as alcohol, fuel oil, lubricating oil, emulsion etc..Mutually distinguish with hard tube,（Rubber）Flexible pipe maximum
It is characterized in that flexible.Compare civilian（Rubber）Flexible pipe, industrial operations environment is more complicated, more severe, equipment is wanted to delivery pipe
Ask also harsher, therefore industry（Rubber）Flexible pipe has from design, to choose production, transport or even the final storage of material
Strict codes and standards.Varied according to the design of applying working condition and the difference flexible pipe of performance requirement, industry（Rubber）It is soft
The optional scope of size of pipe is wider, and P-T region is vast, and chemical-resistance is higher.Industry（Rubber）Flexible pipe application is contained
Each industrial production manufacture and the field of circulation are covered, has been the physics and electrochemical conditions for adapting to every profession and trade operation, generally industry（Rubber
Glue）Flexible pipe has very strict execution standard on the chemical raw material and technique of inside and outside colloid.Such as：Delivery hose is mainly used in
The aspects such as the cleaning of irrigation, gardening, building, fire-fighting, equipment and tank car, agricultural fertilizer, excrement, trade effluent draining.
EPDM ethylene propylene diene rubbers, heat-resisting, resistance to steam, the line of resistance to ozone-ultraviolet and chemical substance.Second the third glue EPDM is by ethene
And copolymerization of propylene is formed, therefore heat resistance, resistance to ag(e)ing, ozone resistance, stability are very outstanding, but cannot sulphur add
Sulphur.To solve this problem, import on EP main chains have the 3rd composition of double-strand on a small quantity and can add sulphur EPDM, generally use temperature
Spend for -50 ~ 150 DEG C.To the polar solvent such as splendid advantage of the repellence such as alcohol, ketone：The good anti-time property of tool and ozone resistants, have splendid
Water-resistance and anti-chemicals, can have good impermeability to gas using alcohols and ketone, high temperature resistant steam.Shortcoming：Three
First EP rubbers is low due to lacking active group, cohesive energy in molecular structure, adds sizing material and is easy to bloom, from stickiness and mutual viscosity
It is very poor, it is not recommended that for food applications or to be exposed among fragrant hydrogen.For this purpose, we set about from the formula of product, rubber is soft
The formula design of pipe will be according to the performance of rubber hose, structure, purposes, auxiliary agent and the phase between the compatibility of resin, each analog assistant
Mutually affect and cooperative effect, and the characteristics of former, the forming factors of comprehensive each side, carry out resin model and various add
The selection of adding assistant.In order to meet high request of the market to rubber hose, developing a kind of various performances is preferably used for
Prepare the ethylene propylene diene rubber of delivery hose.
The content of the invention
To achieve these goals, the invention provides a kind of ethylene propylene diene rubber for preparing delivery hose.
The purpose of the present invention is achieved through the following technical solutions：
A kind of ethylene propylene diene rubber for preparing delivery hose, is prepared by the raw materials in：EPDM160-165 parts,
