Technical field
Silicon rubber/polyurethane comixing thermoplastic elastomer the present invention relates to a kind of dynamic vulcanization and preparation method thereof.
Technical background
Dynamic vulcanization is by thermoplastic (including thermoplastic elastomer and thermoplastic), vulcanizable rubber and vulcanization
The agent melt blending in the presence of certain temperature and shearing force together, rubber in this process, be cut into little particle (point
Dephasing) it is distributed in thermoplastic (continuous phase), while rubber grain completes crosslinking, form thermoplastic elastomer (TPV).It is this
Material has preferable performance, and relatively low processing cost simultaneously.This preparation method is obtained in that high-crosslinking-degree rubber phase.
Therefore the mechanical strength and oil resistivity of TPV are higher.Coran of Monsanto companies in the U.S. etc. (existing name Solutia Inc.) is opened
The TPV (US4130535) of PP/EPDM is sent, and this elastomer was transformed into commodity first in 1980
“Santoprene”。
This material has excellent processability, the high resiliency of rubber, good adaptability, economy and low stain
And the favor in market is obtained, the occasion of present nearly all application rubber can be replaced using Santoprene.But,
Santoprene heat resistances are relatively low, and in some requirement extremely oil resistants, the very high environment of some heatproofs requirement limits this
The application of material.
Urethane thermoplastic elastomer (TPU) is polymerized by isocyanates (monomer) with hydroxy compounds, with good
Oil resistivity, wearability, toughness, resistance to ag(e)ing and cohesive.Adaptation wide temperature range can be obtained with different material.But it
Resistance to ag(e)ing and heat resistance are poor.TPU can be blended with multiple material, the excellent high molecule alloy material of forming properties.Use
Blend, can be not only molded with methods such as extrusion, injections, and more easier to process than TPU.
Silicon rubber refers to that main chain is alternately made up of silicon and oxygen atom, and generally two rubbers of organic group are connected with silicon atom
Glue.Silicon rubber is characterized in significantly height temperature stability, and under the hot environment more than 200 DEG C, silicon rubber remains to keep certain
Pliability, resilience and case hardness, and mechanical property is without significant change.The Weatherproof ageing-resistant performance of silicon rubber is also dashed forward very much
Go out.But the mechanical strength of silicon rubber is poor, only there is medium oil resistant, solvent resistance.Therefore, by dynamic vulcanization method system
Standby silicon rubber/TPU thermoplastic elastomers, will make the advantage of both materials complementary, obtain the thermoplastic elastomer of not only high temperature resistant but also oil resistant.
