Abstract
A high-pressure and high-tem. resistant synthetic rubber is prepared from ethylene-propylene-diene rubber, sulfur, DCP, zinc oxide, stearic acid, antiwear carbon black, spray carbon black, RD, and paraffin through proportioning and multi-step milling. It can be used as sealing material with the advantages of high-temp (up to 225 deg.C) and high-pressure (up to 13.5 MPa) resistance, low cost, high sealing effect and long service life.
Description
The present invention relates to a kind of a plurality of fields such as mine, metallurgy, petrochemical complex, medicine, light textile, food, papermaking, boats and ships and central heating that are widely used in, the high temperature high voltage resistant synthetic rubber that be applicable to cooling, heating, condensation, concentrate, operating modes such as sterilization and waste heat recovery needs the invention still further relates to its manufacture method.
At present, be widely used in the High Temperature High Pressure occasion at China's ethylene-propylene-non-conjugated diene rubber, but because there are defective in its prescription and manufacturing process, so generally can only be high temperature resistant 130 ℃, high pressure resistant 1.3MPa; Put down in writing according to data, external similar rubber also can only be high temperature resistant 200 ℃, so that the use occasion of ethylene-propylene-non-conjugated diene rubber is restricted, can not be used for the High Temperature High Pressure occasion, make sealing element, all need to dispose heat sink at a lot of High Temperature High Pressure applications ethylene-propylene-non-conjugated diene rubbers, as the plate-type heat exchanger rubber sheet gasketing, owing to do not reach high temperature resistant requirement, can't bear the superheated vapour more than 200 ℃, just must install a cooling setter additional.
The objective of the invention is to provide a kind of and high temperature resistantly reach 225 ℃, high pressure resistant Ethylene Propylene Terpolymer high temperature high voltage resistant synthetic rubber and the manufacture method thereof that reaches 13.5MPa.
Ethylene Propylene Terpolymer high temperature high voltage resistant synthetic rubber of the present invention is to be made by the raw material and the weight proportion of following component:
(4045) 100 parts of terpolymer EP rubbers
0.5 part in sulphur
3.5 parts of DCP
5 parts in zinc oxide
1 part of stearic acid
30 parts of high wear-resistant carbon blacks
50 parts of spray carbon blacks
1.5 parts of anti-aging agent RDs
8 parts of Valelinum Liquidums
2 parts of SL-1 processing aids
Making the elastomeric manufacture method of Ethylene Propylene Terpolymer high temperature high voltage resistant of the present invention with above-mentioned materials of weight proportions is:
1, preceding roll temperature is controlled at 50 ℃-60 ℃, back roll temperature is controlled at 60 ℃-70 ℃; High wear-resistant carbon black and spray carbon black mix, and be as mixed carbon black, standby;
2, the terpolymer EP rubber top roll with formula ratio rolls logical 5-8 time, and the time is 4 minutes;
3, put thick pressing bag roller, the time is 3 minutes;
4, continue roll extrusion, be sequentially added into half mixed carbon black, the Valelinum Liquidum of formula ratio and the anti-aging agent RD of formula ratio of formula ratio simultaneously, roll extrusion 5 minutes:
5, be sequentially added into the SL-1 processing aid and the sulphur of the zinc oxide of formula ratio, remaining carbon black, formula ratio, roll extrusion 5 minutes;
6, the DCP and the stearic acid that add formula ratio continue roll extrusion 5 minutes, descend sheet then, promptly get Ethylene Propylene Terpolymer high temperature high voltage resistant synthetic rubber.
Ethylene Propylene Terpolymer high temperature high voltage resistant synthetic rubber of the present invention, through test of many times, and detect through Tieling Research Design Inst. of Rubber Industry, Liaoning Prov., every index all reaches State Standard of the People's Republic of China (GB7759-87), particularly high temperature resistant one has reached domestic highest level, the rubber tensile strength is 13.5MPa behind the 225 ℃ * 240h of superheated vapour, behind the 100 ℃ * 24h of air, the compression set 14.3% of rubber, this rubber is applicable to various high-temperature sealing materials, has high temperature high voltage resistant, long service life, effective, low cost and other advantages.
The present invention is provided by following examples: get
(4045) 100 jin of terpolymer EP rubbers
0.5 jin in sulphur
3.5 jin of DCP
5 jin in zinc oxide
1 jin of stearic acid
30 jin of high wear-resistant carbon blacks
50 jin of spray carbon blacks
1.5 jin of anti-aging agent RDs
8 jin of Valelinum Liquidums
2 jin of SL-1 processing aids
1, preceding roll temperature is controlled at 50 ℃-60 ℃, back roll temperature is controlled at 60 ℃-70 ℃; 30 jin of high wear-resistant carbon blacks and spray carbon black mix for 50 jin, and be as mixed carbon black, standby;
2,100 jin terpolymer EP rubber top roll is rolled logical 5-8 time, the time is 4 minutes;
3, put thick pressing bag roller, the time is 3 minutes;
4, continue roll extrusion, be sequentially added into 40 jin mixed carbon black, 8 jin of Valelinum Liquidums and 1.5 jin of anti-aging agent RDs simultaneously, roll extrusion 5 minutes;
5, add 5 jin of zinc oxide, 40 jin of carbon blacks, 2 jin of SL-1 processing aids and 0.5 jin of sulphur, roll extrusion 5 minutes in order successively;
6, add 3.5 jin of DCP and stearic acid, continue roll extrusion 5 minutes, descend sheet then, promptly get Ethylene Propylene Terpolymer high temperature high voltage resistant synthetic rubber.
This rubber can be used for multiple High Temperature High Pressure occasions such as interchanger gasket seal.
