Description

The TPV elastomer material that a kind of electrical property improves
Technical field
The present invention relates to a kind of TPV elastomer material.
Background technology
TPV is the abbreviation of Thermoplastic Vulcanization, and Chinese is thermoplastic dynamic vulcanized elastomerics or thermoplastic dynamic perduren, is that the rubber particle of solid cure is dispersed in the middle mutually a kind of elastomer material formed of continuous plastics.TPV has physicals and the functional character that is similar to thermoset rubber at normal temperatures, the characteristic that at high temperature has the melt-flow of thermoplastics and process repeatedly, have advantages such as forming process convenience, material reusable edible, high comprehensive performance, now be widely used in fields such as automotive industry, building materials, electronic apparatus, health care and consumer appliance.
Continuous expansion along with the TPV Application Areas, its performance demands is improved easily, the research of relevant functional modification is also progressively carried out, as improves anti-UV performance, improves the fire-retardant fireproof performance, reduces proportion and carry out foaming modification, improve the surface and constantly developed with product innovations such as the adhesive property of metal, anlistatig TPV.
The antistatic modified method of relevant TPV is to add graphitized carbon black in material, owing to adopt the antistatic material of graphitized carbon black preparation to have significantly " exceed and ooze mechanism ", addition is generally bigger, and have only when its addition surpasses threshold value and form conductive network in material, antistatic effect just can embody.People such as the Tian Hongchi of Beijing University of Chemical Technology have studied the conductivity of graphitized carbon black/TPV matrix material, the result shows: along with the graphitized carbon black consumption increases, the volume specific resistance of material reduces, the graphitized carbon black consumption during less than 10 parts the volume specific resistance of material bigger, the volume specific resistance that the graphitized carbon black consumption reaches matrix material after 15 parts is reduced to 10 3And tend towards stability.The EPDM/PP blending ratio has bigger influence to conductivity, and the EPDM/PP blending ratio increases to 50/50 from 30/70, and the volume specific resistance of matrix material reduces; The EPDM/PP blending ratio is greater than after 50/50, and along with blending ratio increases, the volume specific resistance of matrix material is increase tendency.People such as Tian Hongchi find that carbon black/TPV matrix material has the conduction strangeness: the existence of crosslinked rubber phase had both produced repelling effect to the graphitized carbon black particle, produced blocking effect again; The former is favourable to the formation of conductive network, and the latter antithesis.When low rubber phase content is low, increase with rubber phase content, composite material resistance is on a declining curve; When rubber content is higher, increase with rubber phase content, the resistance of matrix material raises.The people such as Tao Yang of the liter of Shanghai day have studied the antistatic TPV of graphitized carbon black modification, added 3~5% graphitized carbon black, and adopted the dispersion agent of polyethylene wax as graphitized carbon black, purpose is to improve sooty and disperses, improve the homogeneity and the stability of surface resistivity, surface resistivity only reaches 10 10, can only satisfy anlistatig requirement.The people such as Tang Zhuo of the liter of Shanghai day adopt the graphitized carbon black 4~8% of high structure, add polyethylene wax simultaneously is dispersion agent, and the surface resistivity of material is reduced to 10 2, but this invention is for not studying than the antistatic effect of few additive (as being lower than 2%).In addition,, separate out easily when addition is too high, may cause some beyond thought puzzlements for the follow-up use of product because polyethylene wax and polyacrylic consistency are relatively poor.Practice and theory all show: rubber is had bigger reinforcement effect owing to carbon black, carbon black can cause the negative effects such as processing flowability decline, elongation at break reduction of material than high filler loading capacity the time.Therefore, reduce the antistatic modifier consumption, avoid low-molecular-weight component to separate out, can reach simultaneously the antistatic or conductive effect of ideal be this area development in future direction.
