After ethylene-propylene rubber(EPR) is broken through 40000 yuan of (ton valency, down with) high pointes in late Febuary, 2011, go up as ethylene-propylene rubber(EPR) market such as the blowout, connect and create all-time high, this kind situation short-term is difficult to change, and the ethylene-propylene rubber(EPR) After-market is expected to continue high.
Along with rapid development of economy, China increases the ethylene-propylene rubber(EPR) demand year by year, and breach continues to increase, and this year, disparities between supply and demand were particularly outstanding.The supply of goods of present foreign producer has reduced 15%～20% compared with last year.Ethylene-propylene rubber(EPR) price one rises and rises again, but because mostly this glue kind is import, and the output in domestic share is few, can't left and right sides product price, the high price situation is difficult to improve.Domestic ethylene-propylene rubber(EPR) market will be main to shake high.
CN 101093736A discloses a kind of mine cable insulation paste, and it contains EPDM, vulcanizing agent, promotor, anti-aging agent, weighting agent etc.The mine cable rubber insulation glue for preparing not only can satisfy the standard-required of cable, but also has the characteristics of environmental protection simultaneously.But,, influenced its commercialization because the EPDM cost is higher.
CN 101704975A discloses a kind of mine cable insulated hull.This cable is used insulation rubber; This cable rubber is made by following raw materials according, and each raw material calculates according to mass percent: terpolymer EP rubber 39.14%, zinc oxide 3.52%, anti-aging agent RD 0.97%, paraffin 1.96%, Triple Pressed Stearic Acid 0.39%, silane coupling A-1720.78%, superfine talcum powder 15.66^%, calcium powder 11.74% etc.This cable compound micromicro is satisfying the use standard, but its basic rubber all adopts terpolymer EP rubber, causes its cost to raise, and has influenced its commercialization.
Lasting high along with the EPDM price; Cause adopting EPDM to rise as the cost of mine cable rubber insulation glue; Seriously influenced the commercialized development of EPDM mine cable rubber insulation glue; Limited the use of EPDM greatly as mine cable rubber insulation glue, study a kind of can satisfy the mine cable request for utilization simultaneously lower-cost mine cable rubber insulation glue seem very important.
Summary of the invention
To the deficiency of prior art, the object of the present invention is to provide a kind of mine cable rubber insulation glue, be issued to the purpose that reduces cost in the prerequisite of the use standard that satisfies mine cable.
In order to achieve the above object, the present invention adopts chlorinatedpolyethylene to mix with EPDM, and add additive such as vulcanizing agent plasticate, mixing, and then prepare excellent performance and lower-cost mine cable rubber insulation glue.
Mine cable rubber insulation glue of the present invention, each component of its raw material is by weight ratio:
Wherein, the mass ratio of terpolymer EP rubber and chlorinatedpolyethylene is 3: 1.
As preferred version, mine cable rubber insulation glue of the present invention, each component of its raw material is by weight ratio:
Wherein, the mass ratio of terpolymer EP rubber and chlorinatedpolyethylene is 3: 1.
EPDM of the present invention is the rubber that the copolymerization through ethene, propylene and non-conjugated diene hydrocarbon obtains, and belongs to polyolefine family, has good vulcanization characteristics.In ethylene-propylene copolymer, pass through again the copolymerization alkadiene and import unsaturated link(age), thus can be through the vulcanizing agent sulfuration.Alkadiene is not special to be limited, and can use for example 5-ethylidene-2-norbornene, 1,4-hexadiene, Dicyclopentadiene (DCPD) etc.The present invention selects for use and is applicable to that line cable industry the 3rd monomer is the 3722P terpolymer EP rubber of ENB (5-ethylidene-2-norbornene) type.Because the molecular structure of ethylene-propylene rubber(EPR) is nonpolar saturated superpolymer, so pure second third cross-linked rubber has perfect electrical insulation capability.EPDM has remarkable anti-O
3Aging resistance.The weather resistance of EPDM is excellent, can be under the harsh climate condition as long term operation under severe cold and hot, Exposure to Sunlight and rainy, drying and the moist envrionment conditions.It is more excellent to contain anti-sunlight of sooty cross-linked rubber and UV resistant performance.
Chlorinatedpolyethylene (CPE), structural formula are [CH
2-CHCl-CH
2-CH
2]
nCPE is made through the chlorination replacement by high density polyethylene(HDPE) (HDPE).In rubber industry, CPE can be used as high-performance, high-quality specialty elastomer, also can wait other blend rubber to use with ethylene-propylene rubber(EPR) (EPR), butyl rubber (IIR), paracril (NBR), chlorosuphonated-polyethylene (CSM).
