Description
Technical field
The present invention relates to EPDM rubber technical field of paddling, more particularly to one kind is paddled environmentally friendly EPDM rubber material and its system
Preparation Method.
Background technology
Carbon black is the important reinforcing agent and filler of rubber, it is possible to increase the mechanical performance of rubber, global carbon black are total
More than the 60% of amount is used for rubber industry, is to be only second to rubber in rubber industry to occupy deputy important source material.Carbon black is to rubber
The humidification of glue depends primarily on the property of carbon black, such as the surface chemical property of particle size, the morphology of the aggregate and particle
Deng carbon black particle is thinner, structural higher, and enhancing effect is better.
Ethylene propylene diene rubber (EPDM) is a kind of excellent water-fast, chemicals-resistant, ozone proof Multifunctional elastic body, often quilt
For in rugged environment, often paddling or sewage treatment area is used as encapsulant.Because water quality deterioration is increasingly severe,
Contain the materials such as substantial amounts of organic matter, chlorine residue, heavy metal in water.《Rubber reference》Published on the 6th phases of volume 44 in 2014
" mechanism of degradation of the EPT rubber packing pad in chloride urban water " describes the chlorine residue in water once text and can not tied
The free carbon black adsorption and enrichment on EPDM molecules is closed, causes EPDM rubber to be degraded, cl concn is higher, and degraded is more serious, in addition,
The heavy metal of free carbon black absorption accumulation can also reduce its service life, influence valve performance to the oxidation of promotion rubber.
The content of the invention
The defects of present invention is in order to make up prior art, there is provided one kind is paddled environmentally friendly EPDM rubber material and its preparation side
Method.
The present invention is achieved by the following technical solutions：
One kind is paddled environmentally friendly EPDM rubber material, includes each component of following parts by weight：
Ethylene propylene diene rubber 100-150, salt loading carbon black 110-165, paraffin oil 15-20, zinc oxide 5-10, stearic acid 1-
2nd, flow promortor L-24 2-3, activating agent PEG4000 2-3.5, inner pattern releasing agent applicable KL-3Q1-2, sulphur S-80 1.2-1.8, promotion
Agent DM 0.8-1.2, accelerator CBS 1.5-2.5, accelerator TT 0.3-0.5, accelerator ZDBC-75 1-1.5, accelerator
DPTT-70 0.6-1.1。
Described ethylene propylene diene rubber preferably 4045 ethylene propylene diene rubbers.
Described salt loading carbon black is preferably after salting liquid saturated process according still further to 1:The N550 charcoals of the ratio mixing of (1-5)
Black and N770 carbon blacks.
Described salting liquid be mass percent concentration be 1-5% AR magnesium chloride solution, Klorvess Liquid,
One kind in sodium chloride solution, liquor zinci chloridi.
A kind of preparation method of described environmentally friendly EPDM rubber material of paddling, comprises the following steps：
(1) prepared by salt loading carbon black：With salting liquid immersion carbon black processing 5-12h, processing terminate after with deionized water repeatedly
Cleaning, removes chlorion completely, and then material is handled through drying, sieving, standby；
(2)：Raw material is got ready by proportioning, and ethylene propylene diene rubber is first added into the mixer mixing that rotating speed is 10-15 revs/min
3-5 minutes, banbury rotating speed is then set as 15-20 revs/min, then zinc oxide, stearic acid, accelerator CBS, flowing are helped
Agent L-24 is added, and is kneaded 1-2 minutes, and banbury rotating speed then is set as into 20-30 revs/min, then by salt loading carbon black, paraffin
Oil, activating agent PEG4000, accelerator ZDBC-75, which are added, is kneaded 3-5 minutes in banbury, add leftover materials after being kneaded, send
Enter to mill and turn refining 3-6 times, film is obtained after cooling, after film temperature is down to below 40 DEG C stacking produce.
The present invention, as technological improvement point, is carried out from the adhesive force for improving carbon black and rubber particles using salting liquid to carbon black
Salt loading processing, the carbon black impurity content after processing is lower, and agglomeration is greatly improved, structural higher, and activity is more
Height, it is stronger with the adsorption capacity of rubber particles, the amount for the carbon black that dissociates in rubbery system is effectively reduced, so as to prevent rubber material
Expect accumulation in environment of paddling to the bad ion of environment and accelerated ageing, and the carbon black enhancing effect after salt loading processing is also more
Add protrusion；In addition, in process of production by controlling the speed of banbury to reach the melting effect being more uniformly distributed, obtained film
Intensity is high, and surface is smooth, and plastic emitting is fast, and surface goes out excellent anti-aging and sealing property, service life and peace in equipment of paddling
Full property is improved.
