Description

A kind of binder composition and a kind of organosilane crosslinked polyolefin elastic-body insulating materials and its Preparation method
Technical field
The invention belongs to insulating materials field, and in particular to a kind of binder composition, further relate to a kind of crosslinked with silicane polyene Olefin elastomer insulating materials, and this organosilane crosslinked polyolefin elastic-body insulating materials preparation method.
Background technology
Electrical equipment cable be from the distributor point of power system electric energy be transferred directly to various electrical equipments, utensil electricity Source connection line electric wire, various works, agriculture, industrial and mining enterprises are used equip in electric hookup wire and control signal electricity Line cable.Such product uses widest in area, kind to combine the characteristic and use environment bar of equipment used at most and mostly Part determines the properity of product.
The conventional insulating materials of electrical equipment cable is EP rubbers (EPDM), because EPDM has the weatherability, resistance to of brilliance The performances such as ozone, electrical insulating property, low compression set, high intensity and high elongation rate, therefore EPDM is in ship cable, locomotive It is used widely in the fields such as cable, cable for wind power generation, mine cable, cables of nuclear power.
However, processing EPDM needs to squeeze rubber equipment, this is different from extrusion apparatus needed for common cable production.Present EPDM's Crosslinking process needs continuous vulcanization equipment, and this enterprise for allowing for producing electrical equipment cable needs expensive company's sulphur equipment.One A little medium and small cable enterprises are due to powerless buying even sulphur equipment, so as to cannot be introduced into electrical equipment field of cables.Connect sulphur equipment simultaneously Due to needing HTHP, substantial amounts of electric power can be consumed, this also significantly increases the burden of enterprise.Due to EPDM cross-linking process Need by even sulphur equipment, heating pressure process in, need to have cable pass through even sulphur equipment so that above hundreds of meters of cable without Method is used, and causes to waste.Such characteristic is also determined simultaneously is adapted to together using the EPDM electrical equipment cables for doing insulating materials Specification is continuously produced, if production nonstandard product, can also greatly improve cost.In addition, high temperature vulcanized process can produce it is substantial amounts of Toxic and harmful gas, pollutes environment, and also the health of staff can be caused to seriously endanger.
Chinese patent CN101245169 discloses a kind of water cooking preventing low-smoke non-halogen flame-proof silicone hydride crosslinked polyolefin composition, However, using it for the production of electric wire, the mechanical performance and specific insulation shown is all substantially not enough.In addition, Japanese Patent JP2012255077A discloses a kind of manufacture method of electric wire formed body, including：Process I, by (a) polythylene resin, (b) block copolymer of polypropylene-based resin, (c) aromatic vinyl base class compound and conjugated diene compound etc., (g) silicon Alkane coupling agent etc. carries out melting mixing to manufacture (A) crosslinked with silicane fire retardant polyolefin；Process II：It is poly- by what is selected in (a)~(c) Compound and (i) silanol condensation catalyst carry out melting mixing to manufacture (B) silane alcohol catalyst resin combination；And process III：Above-mentioned (A) and (B) are mixed, the melt-shaping on conductor is crosslinked in presence of water.The Japan Patent is adopted With the method for silane cross-linked polyolefin, the machinery of the material of acquisition still has much room for improvement.
Polyolefin elastomer (Polyolefin elastomer) (POE) is DOW chemical companies of the U.S. using metallocene to urge The thermoplastic elastomer (TPE) with narrow molecular weight distribution and the distribution of uniform short-chain branch of agent.This elastomer it is main Performance is protruded very much, has exceeded conventional elastomers in very many performance indications.POE molecular structures and ethylene propylene diene rubber (EPDM) it is similar, therefore POE can also have the excellent properties such as ageing-resistant, resistance to ozone, resistant to chemical media, by handing over POE Connection, the heat resisting temperature of material is enhanced, and permanent deformation reduces, and the main Mechanical such as tensile strength, tearing strength has very big The raising of degree.
