MBS resin is in particle design concept based on the synthesis of
functional polymer material, is through the emulsion graft
polymerization of ternary polymer, on the microstructure of the
typical core-shell structure, the core of the particle is a
slightly crosslinked with low shear touch styrene-butadiene rubber
core, mainly improve the impact toughness of the polymer. The shell
is a hard shell formed by the grafting of styrene and methyl
methacrylate. The main function of MMA in the shell layer is to
improve its compatibility with PVC so that MBS can be distributed
evenly in PVC body. St is mainly to improve the refractive index of
MBS resin to make the MBS have the refractive index similar to PVC,
so MBS resin is a typical particle dispersive toughening modifier.
It is semi-compatible with PVC, that is, it has good interface
compatibility with PVC resin, and keeps the particle shape intact
in the PVC/MBS system. When MBS is added in a small amount, it has
a good dispersibility in PVC, which is not a dispersed type of "sea
- island" structure, which can not be used to transmit shock
energy, and the material toughening effect is not good. With the
addition of MBS resin, dispersed particles gradually coalesced to
form island structure. When materials by external shocks, rubber
core is the concentration of MBS resin, make its produce
deformation, and inducing crazing and shear zone around, through
the silver lines and disperse the shear zone and absorb the impact
energy and formed the material transition from brittle fracture to
ductile fracture, toughening and to achieve.
