Description
Technical Field
The invention belongs to the field of high molecular compounds, and relates to a synthetic method of MBS resin.
Background
The MBS resin is a terpolymer prepared by emulsion graft polymerization, is a novel high molecular material synthesized under the concept of particle design, and has a typical core-shell structure on a submicroscopic structure. The core of the material is a rubber phase spherical core with the diameter of 50-300 nm, and the rubber phase spherical core can change the shape and absorb and disperse impact energy when being impacted by external force; the shell grafted by styrene and MMA is arranged outside, and because the solubility parameters are similar, the shell part plays a role of an interface adhesive between PVC and rubber phase particles, a homogeneous phase can be formed in the processing and mixing process, and the rubber phase is dispersed in a PVC continuous medium in a particle state. Therefore, the toughness of the PVC can be improved by more than several times by adding a small amount of MBS into the PVC.
In the prior art, only methyl methacrylate, styrene-butadiene latex and other raw materials are added when MBS resin is synthesized, so that the chromaticity, haze and impact strength of PVC have obvious defects.
